Lumia 925 description. Interface and navigation. Functionality

After the announcement, which took place on May 14 in London, we can say with complete confidence that Nokia has finally finally moved into its own alternative universe. In this universe the operating system Windows Phone brought to perfection, and competitors cannot keep up with it. Wasn't here Apple presentations iPhone 5 with a high-quality camera, HTC One in a metal case and Zoe, which provides a set of fresh tools for processing images received from a smartphone, and sales have not started Samsung Galaxy S4 with an excellent 12 MP camera module. In the Nokia universe, the concept of a top-end smartphone no longer means maximum characteristics, it is important to call it a flagship - and the job is done, and the most popular image service here is Hipstamatic, and no one has heard of Instagram.

Nokia smartphone Lumia 925 is a direct continuation of last year's Finnish flagship, Lumia 920, announced in September. It is important to note that the 925 is not the next generation of Lumia, but only a cosmetic update to the line, and Nokia will still have a real flagship in 2013, but, as you can see, the company decided to organize a separate event for a simple update. Is this related to the fact that Nokia Lumia Is 925 really so interesting and important that it needed to be given maximum attention? Hardly. Perhaps the release of the real flagship is being postponed and Nokia understands that it will only be able to show it by winter, and a lull of a year and a half since the announcement of the Lumia 920 in September 2013 would look very strange, and therefore with the presentation of the Lumia 925 the company is simply creating an intermediate point until the release of the real flagship to occupy the minds of those waiting. I don’t know whether this is true or not, but it’s hard for me to come up with any other explanation for this presentation.


By majority Nokia settings Lumia 925 is an exact copy Nokia Lumia 920 - the same display in diagonal and resolution, the same platform, camera module. But there are also differences, both in characteristics and in software and housing, let's talk about them.

  • First, the Nokia Lumia 925 has an aluminum frame, that is, the edges and ends, and the lid is made of plastic, while the 920 is entirely made of plastic (polycarbonate)
  • Second, although the 925 is almost identical in width and height to the 920, new smartphone noticeably thinner (8.5 mm versus 10.7) and, more importantly, much lighter (139 grams versus 185). As you know, the Nokia Lumia 920 weighed like a cast iron vat, so the weight reduction of more than 40 grams in the new product is clear progress
  • Third, the Nokia Lumia 925 has a Smart Camera mode (later it will appear in other models in the series). WITH using Smart Camera can take up to 10 frames and then edit them using one of several effects: Best Shot, Action Shot and Motion Focus.
  • Fourth, the Nokia Lumia 925 (and then Windows Phone 8 in general, probably) will have the Hipstamatic application, an analogue of the popular Instagram service (it itself is still not available for WP8)

Now about the sad stuff.

  • Unlike the Nokia Lumia 920, which had 32 GB of internal memory, the 925 has only 16 GB without expandability
  • Unlike the Lumia 920, which had wireless charging, the Lumia 925 does not have it, and in order for this feature to appear, you will need to install a special additional plastic panel on the back of the device
  • The Nokia Lumia 925 uses an AMOLED screen, for some this is a plus (rich and very contrasting picture), but for others, on the contrary, it is a minus (rich and very contrasting picture, burning out the eyes)

As a result, after getting to know the Nokia Lumia 925 more closely, we will see not an update of the previous model, but a slightly modified version of it: less flash memory, no wireless charging, but the body has become lighter and is made partly of aluminum, and new opportunities have appeared for working with pictures from the camera. True, all this is already available in top smartphones from HTC and Samsung, if we talk about the camera and effects for pictures. As for the mention of Hipstamatic, this Nokia tradition of talking at presentations about the appearance of another program for Windows Phone 8 is no longer funny. Doesn’t anyone there understand that it’s just stupid to so openly admit the weakness of the chosen system? It’s better to just remain silent than to celebrate the emergence of just one of the analogues (!) of the popular Instagram service for the platform being used.

Global sales of Nokia Lumia 925 will begin in June at a price of 479 euros (the actual price tag including taxes will be higher), in Russia the device will be launched approximately in the third quarter, there is no information on the price yet. What else can I say? A separate presentation of the smartphone seems like a strange decision; there is not much new in it compared to last year’s Nokia Lumia 920. It is not clear why they would release an update with less memory and without wireless charging, which Nokia itself has been so zealously advertising all this time. In the end, it seems that we will all now be looking for some logical explanations for the actions of Nokia’s management, although in reality there are simply no such explanations. The company itself has not known for a long time what they are doing and why, and this whole circus with the Lumia line is clearly confirmed by a random photo from the last presentation of Nokia Lumia 925.


Vice President Jo Harlow spent part of the presentation of the Nokia Lumia 925 in a basketball uniform, so we can well expect that at the next Nokia presentation Stephen Elop will perform in sweatpants and an Adidas tracksuit.

The latest Gartner report only confirms that Nokia is far from its best form. Thus, over the past year, the company has dropped from 8th place in smartphone sales to 10th, while the share of smartphones in the total number of mobile phones sold is only growing. Some are hoping for the company's next flagship with a new camera, while others are still waiting for Nokia to switch to the Android platform. The majority, as statistics show, simply buy a smartphone from Samsung, HTC or another manufacturer, sending their latest handset with the Nokia logo to the trash bin or to the shelf as a souvenir.

Level 0 cache (L0)

Some processors have L0 (level 0) cache, which is faster to access than L1, L2, L3, etc. The advantage of having such memory is not only higher performance, but also reduced power consumption.

4 kB + 4 kB (kilobytes)
Level 1 cache (L1)

Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and works much faster than both system memory and other cache levels. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2.

16 kB + 16 kB (kilobytes)
Level 2 cache (L2)

L2 (level 2) cache is slower than L1 cache, but in return it has a higher capacity, allowing it to cache more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or in RAM memory.

1024 kB (kilobytes)

Nokia Lumia 925:: Review:: Design and Features

The device turned out to be very recognizable in appearance - as far as this is in principle possible today, in an era of very similar-looking gadgets that are barely distinguishable from each other. Aluminum frame frame, display with smoothed glass edges, “erotically” protruding camera module :) A thin and light smartphone fits comfortably in any hand despite its considerable dimensions.

Metal is partially used in the decoration of the device - the perimeter frame is made from it. Back cover remains plastic and is not removable.

The front panel, completely covered with glass with beautifully and conveniently “filled” edges, hides the front camera and sensors (on top), as well as three control buttons (on the bottom). The control buttons are illuminated in white, but are clearly visible even when the backlight is turned off due to reflection of external light.

The back cover contains a slightly protruding (by a millimeter) camera module and an LED flash, as well as a speaker perforation and three contacts intended for a protective case with a built-in receiving antenna of the proprietary wireless charging system.

The right side is full of buttons - the volume rocker is on top, the unlock button is in the middle (it fits comfortably under the thumb), and the camera button is at the bottom. The left side is completely empty.

The top edge contains a slot for a micro-SIM card that can be opened with a paperclip (which, pleasantly, extends but does not fall out completely!), a USB connector, and a headphone jack. The bottom edge is empty.

Nokia Lumia 925:: Review:: System/User Interface

Moving from bottom to top unlocks the screen.

The desktop consists of “live” tiles with updated information.

The size of the tiles, their color, as well as the background color change - this limits the personalization of the interface:

There are two “desktops” - “main” and “secondary”. They change with a horizontal slide across the screen. The “main” one contains large tiles of frequently used applications, while the “secondary” one contains small “non-living” shortcuts for all programs installed on the smartphone.

Applications

Nokia Lumia 925:: Review:: Main functions

Mail. The mail application allows you to attach only a photo to a letter - all other files can be sent via email only from the appropriate programs. An office document from an office application, an MP3 file from an audio player, etc.

Calendar/Planner

Alarm

Calculator

Gallery. The possibilities for photo editing are very limited, but in fact there is exactly what you need without unnecessary functions that few people use. For example, the “Fix” button with one touch evens out the brightness, turning the photo into an almost HDR photo!

Audio player. The player is like a player. There are no proprietary features, such as a built-in music recognizer, but the sound is not bad and you can use it. Although, if you're not used to it, it's annoying that the equalizer adjustments can only be accessed from the settings menu, but not from the menu of the player itself... There's also a lack of album cover swapping, which is why the music library interface looks dull.

Radio

Video player. Traditionally simple, but this is the kind of simplicity that is “worse than theft” :) If the lack of settings is easy to come to terms with, then the lack of codecs to support formats other than MP4 is bad! Movies will have to be converted before downloading (if you have them in AVI or MKV), and there is no sensible alternative player in the “market” yet...

Children's room. Branded "Windows" built-in service for restricting access to applications and content - by turning it on, you can safely give the phone to a child without fear that he will open adult applications, access the Internet or delete some data. “Children’s” changes the phone interface to a simplified one, with icons of pre-marked allowed programs, without settings, etc.

Nokia Lumia 925:: Review:: Display

The display in Lumia 925 is 4.5-inch, made according to AMOLED technology, with a resolution of 768x1280 pixels. On top of the screen is covered with tempered Gorilla Glass with features recognizable from other flagships. Nokia models rounded edges. The display matrix is ​​very juicy (I would like to say - “juicy in a Samsung way”!), with impeccable viewing angles, and high brightness. The display demonstrates excellent behavior in the sun thanks to the proprietary ClearBlack polarizing layer and electronic system image correction, which works when the brightness level is set to automatic adjustment. In this case, the system itself changes the color scheme and other parameters, achieving the best display.

The image on the screen can be adjusted to your own preferences manually by changing the gamma:

The most interesting features of the screen are the ability to operate with gloves (activated by selecting high sensitivity in the settings of the “Display + Sensor” section), as well as the constant backlighting of the clock and notifications in standby mode, used for the first time on Windows Phone devices, plus the ability to “wake up” the device with a double tap screen. This extremely convenient (allowing you to easily find your phone in a dark room!) function was previously implemented on smartphones such as N8, N9, E7, and 808, but it has not been seen on Windows phones before, just as it has not been seen, by the way, anywhere else , except for devices of the Finnish manufacturer. The key to its operation is the AMOLED screen, in which you can highlight several dozen pixels without wasting energy, without activating the rest and without turning on the battery-consuming backlight, as you would have to do when implementing this in a TFT screen.

Nokia Lumia 925:: Review:: Memory

The phone's memory is its weakest point, for which the 925 has already been given a lot of "presentation". The device has 16 built-in gigabytes (actually 15) and does not have an extension for the card... And it does not even support connecting USB drives via OTG! By today's standards, this is very strange, and will oblige the owner to seriously think about downloading various types of content, promptly change watched movies and boring music with new ones, and also often upload photos to a home computer or at least to the Microsoft SkyDrive service... I do not deny the prospects and amenities cloud storage, but in many cases their use seems unnecessary and a multi-step “workaround”, while uploading files to the internal memory array is straightforward, simple and one-step.

Nokia Lumia 925:: Review:: Camera

The Lumia 925 has an 8.7-megapixel matrix with an optical stabilization system, which showed itself superbly in the Lumia 925. The number of lenses in the 925’s lens has been increased to six, but in general the camera is not a fundamental departure from its predecessor. It is also good - well, maybe “a little better” :) I think there is no point in changing the 920 to 925 for those who have their first smartphone.

Lumia 925 camera specs:

Matrix – 8.7 megapixels
Matrix size: 1/3 inch
Lens - Carl Zeiss Tessar
Number of lenses – 6
Focal length - 26 mm (35 mm equivalent)
Aperture - f/2.0
Shutter – electronic
Focus point – any

For comparison, the Nokia N8 is a well-deserved oldie with excellent photography quality to this day:

Characteristics Nokia cameras N8:

Matrix – 12 megapixels
Matrix size - 1/1.8 inches
Lens - Carl Zeiss Tessar
Number of lenses – 5
Focal length - 28 mm (35 mm equivalent)
Aperture – f/2.8
Shutter - mechanical
Focus point - center only

What can we say from these numbers and characteristics? Clear dynamics of simultaneous growth of all characteristics in the style of Soviet aviators “higher, and higher, and higher!” (c) - no. Compared to the 920, even the favorite tool of marketers - the number of megapixels - has not increased... There are still 8.7 of them.

At the same time, as is known, the quality of shooting is simultaneously influenced by several parameters. One of them is the physical size of the pixel, which depends on the number of megapixels that make up the matrix and its dimensions. The larger the pixel, the larger its area and the amount of light it receives, which means the higher its light sensitivity and the less noise it generates. Lumia 925 and N8 have different sensor sizes and number of pixels (not in favor of 925 - and quite significantly!), and the size of a single pixel in N8 is also larger - about 1.2 times. At the same time, such a lens parameter as the aperture number is better on the Lumia 925 - 1.4 times larger - and it, like the pixel size, determines the amount of light falling on the matrix. Some parameters are partially compensated by others. But optical stabilization in the 925 is a truly real and impressive achievement of recent times, in which Nokia is certainly a leader in relation to both competitors and its own very successful camera phones of past years. Optical stabilization significantly improves the quality of shooting at twilight without a flash, when the latter illuminates the foreground, leaving the background in the dark.

Continuing to quickly compare the specifications, let’s mention the mechanical shutter of the N8 versus the electronic shutter of the 925. This, it must be said, is not a very critical rivalry, since the advantages of “mechanics” are more relevant in the presence of a fast xenon flash, which is not present in the 925. And in general, the confrontation between xenon and LED today does not look so acute in principle, since the power of LED flashes has increased, but xenon flashes have not increased, being limited by the acceptable thickness of phones. The minimum macro shooting distance of the 925 is better - but two centimeters of difference (8 and 10) hardly changes anything. In terms of shooting speed, the N8 lags far behind the 925 (the interval between shots is about 2 seconds and there is no burst mode at all), but now we are moving from the properties of the camera, as such, to the processor platform, which in the N8 is very outdated in modern times...

How can we summarize the conversation about the Lumia 925 camera?

If you look at the shooting quality of such modern leading camera phones as HTC One X, Samsung Galaxy S4 or Sony Xperia Z, then, in my opinion, they are all comparable to the Lumia 925, showing slightly better or slightly worse results in certain conditions, but at the same time confidently standing in the same ranks. Sony Xperia Z has better reaction to backlight, Samsung Galaxy S4 has better focusing and shooting speed, Lumia 925 behaves better in low light conditions. At the same time, a number of shooting factors, such as a slight change in the camera angle, all other things being equal, can turn the leadership of one device in favor of another, therefore, as usual, there is no unconditional flagship.

Nokia Lumia 925:: Review:: Performance and Power

The power and performance of the device are similar to the Lumia 920 - it has the same processor (1.5 GHz Qualcomm MSM8960), the same video accelerator (Adreno 225), the same gigabyte of RAM. This is not a record-breaking platform by Android standards, but for the highly optimized and undemanding hardware operating system, WP8 really doesn’t need anything else yet - on this hardware, the smartphone copes with any tasks, while remaining quite economical.

To assess energy efficiency, I conduct a test traditional for my reviews: I charge the battery to 100%, reboot the device to clear the memory of clogging programs, turn off all wireless interfaces except cellular communication, I set the screen brightness and volume to maximum. I start a regular movie in AVI format, lasting 1 hour 23 minutes and weighing 1.45 GB. After finishing the movie, look at the remaining battery charge:

90% is an excellent result. It’s a rare “android phone” that manages to do this – and even then, only if it has a special powerful battery. For comparison, the results of other WP smartphones with similar characteristics on the same test:

Nokia Lumia 920 – 80%
Samsung Ativ S – 85%

Nokia Lumia 925:: Review:: Windows Phone 8

The Windows Phone 8 operating system still raises questions and complaints among many, despite the fact that the range of smartphones on it is significantly inferior to Android, and not everyone who is “angry” has dealt with it. Therefore, a review of each new gadget can be safely provided with a mini educational program for those who are not in the know, as well as an “injection of logic” for those who like to “throw it at the fan” or start an “OS squabble”. Honestly, doing this all the time is extremely tedious, but occasionally it’s probably worth it :) Let’s go over the main strategic differences between the two systems (Android vs WP8), which are often opposed to each other, and not in favor of the latter.

The WP8 interface in the form of two screens with columns of icons, and Android with its 5-7 interchangeable desktops, do not have any advantages over each other - they are simply implemented differently and getting used to one or the other is a matter of a couple of days. The only caveat is that on Android the appearance of the interface can be changed quite flexibly, but on WP8 the personalization options are limited. This is the case, but the severity of the “problem” is usually exaggerated - sometimes even seasoned geeks, in the excitement of “system-fucking,” pretend to be schoolgirls suffering from the inability to stick a bow or other trinket in the desired place….

- "Absence" file system in WP8 - a somewhat unusual moment for many. In Android you can look at the list of files on your phone, create new folders and organize content, but here this will not work - the content does not lie in memory “as is”, but is tied to the corresponding programs. Video and audio “live” in the player, texts in the reader or Office, pictures in the viewer, etc. And even by mail, files of various types can be sent not from the mail application, but from the corresponding applications: MP3 - from the player, DOC or EXCEL - from Office, etc. From a “traditional” point of view, this can be considered as a disadvantage, but in reality it’s just a feature and doesn’t cause any problems.

CPU race. In this, as many mistakenly think, WP8 loses, because not a single brand has yet presented a quad-core smartphone on the Microsoft operating system. However, the performance of the systems is not comparable - WP8 is significantly better optimized and at this stage does not need 4 or more core “stones” at all.

App store. For now it's real weakness WP8. Take, for example, video playback - the native player “eats” only MPEG-4 and requires preliminary conversion of “avishek” and “emkavashek”, and there is only one alternative - YXplayer, which is not free and, what is worse, is crude... Another one a real example is video recording programs. There are 5-6 of them in the Marketplace, both paid and commercial (Road Vision, Road Tracks, MyDVR, CVR, etc.), but none of them work in the background - that is, use video recording and navigation at the same time ( which, you see, is completely natural for a driver!), is impossible... The absence of many popular games on Android and iOS is also worth noting - for example, one of my friends did not buy a WP-phone only because it was impossible to play his favorite Metro Surfer on it... Well etc. and so on…. The somewhat slow development of the application store cannot be blamed on Nokia, of course. But if at an early stage of eco development Windows systems Phone, it was customary to pay more attention to hardware, but now, when in WP-lines from different manufacturers powerful flagships with excellent displays, processors and cameras began to appear, the lag of the application store began to focus more attention on itself...

The proprietary advantages of WP8 - they partly compensate for the disadvantages, as is usually the case in our world of imperfect things :) These (advantages) of WP backgrounds traditionally and deservedly include HERE - free pre-installed navigation around the world, flawlessly working support for office files, ease of learning the operating system. All this does not make the system worse or better than android or iOS - for everyone, their personal preferences in certain details become decisive. But, I repeat, it is completely incorrect and groundless to put WP8 on some lower level in relation to its competitors - they all stand next to each other quite confidently.

Nokia Lumia 925:: Review:: Conclusions

The device leaves a highly positive impression – especially for those who are already accustomed to counting great camera in a smartphone is the norm, and not an “auxiliary-optional” element. The ergonomics are top notch, the performance is impeccable, the display is gorgeous, and LTE will provide the fastest mobile Internet speeds to date. On the technical side, there are only complaints about the amount of memory - however, the complaints are serious: still, 16 GB without the possibility of expansion for an expensive flagship device for almost 25,000 rubles is ridiculous... It’s also strange to see the absence of wireless charging with a charging case in the background for a penny in cost very high price of the phone. Few people bother buying additional accessories, and this seems to be a serious marketing miscalculation - wireless charging, this spectacular potential advantage over competitors, is practically not realized, fading into the background and getting lost...

Regarding the price of the device, it is still advisable to suggest being patient and not getting excited. The same Lumia 920 fell in price over six months just to a moderately tolerable price - from 25,000 rubles to 20,000. There is no reason to believe that the price of the 925 will not “settle down” in the same way.


General characteristics

Type

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

Modern smartphones can use not only regular SIM cards, but also their more compact versions micro SIM And nano SIM. An eSIM is a SIM card integrated into the phone. It takes up virtually no space and does not require a separate tray for installation. eSIM is not yet supported in Russia. Glossary of terms for the category Mobile phones

Almost all modern smartphones have Wi-Fi and USB interfaces. Bluetooth and IRDA are a little less common. Wi-Fi is used to connect to the Internet. USB is used to connect your phone to a computer. Bluetooth is also found in many phones. It is used to connect wireless headphones, to connect the phone to wireless speakers, as well as for transferring files. A smartphone equipped with an IRDA interface can be used as universal remote control remote control. Glossary of terms for the category Mobile phones

Memory and processor

CPU

Modern phones and smartphones usually use special processors - SoC (System on Chip, system on a chip), which, in addition to the processor itself, houses the graphics core, memory controller, input/output device controller, etc. Therefore, the processor largely determines the set of functions and device performance. Glossary of terms for the category Mobile phones

Qualcomm MSM8960, 1500 MHz Number of processor cores 2 Video processor Adreno 225 Built-in memory capacity 16 GB RAM capacity 1 GB

Unfortunately, while the Lumia 925 was reaching our test laboratory, two more new flagship devices were released, and the Finnish company itself came under the ownership of Microsoft. But in light of the price reduction for the dethroned flagship, interest in the device will only increase, and a review will certainly not be out of place.

Let me remind you that the Lumia 925 is almost the same 920 model, but without such disadvantages as a large body thickness and a decent weight of the device. It is worth saying that for a weight reduction of 45 grams and a 2 mm thinner body, the older model lost wireless charging and received half as much built-in memory.

For Lumia 925 Nokia has released special cases with built-in charger Qi standard, when used, the thickness and weight of the smartphone again turns into a Lumia 920.

  • Incredibly beautiful clip for removing a SIM card
The fashion for installing slots for SIM cards in smartphones, from which it is impossible to remove the card with the help of human hands alone, and installed by Apple, was picked up by Nokia back in 2008. Apparently, the company decided not to change traditions and installed a slot that can only be opened using a paper clip. Overall, the Apple engineer who originally came up with this can only wish to rot in hell.

The standard Nokia WH-208 headset is equipped with a set of rubber bands for different ears and actually sounds quite good. When buying a smartphone, you don’t have to spend money on good headphones.

Appearance and ease of use

The design of the Lumia 925 has become decidedly cooler than that of its predecessor, the 920 model, especially since it uses such pleasantly cool aluminum and matte polycarbonate.


To the delight of hipsters, we can add that on the white or gray prolycarbonate lid you can draw excellent drawings with colored pencils, and then wipe them off with a damp cloth. Despite the average screen size, the smartphone is quite wide and does not fit very comfortably in the hand.
The left and bottom edges of the device are completely free of any connectors or buttons.


The SIM card slot, additional microphone, headphone jack and microUSB cable are located on the top edge, and the volume rocker, lock and camera buttons are located on the right edge. All the buttons stick out quite strongly from the body and, quite often, there are false activations of the camera button when using the smartphone with the right hand.

The front of the smartphone is protected by Gorilla Glass 2. Under the display there is a standard Windows Phone set of touch buttons. Unlike the 920 model, here they are located more compactly with less space from the bottom edge of the device and the bottom edge of the screen. But this creates some problems when using a smartphone as a camera, because the touch buttons fall just under the palm of the right hand and during shooting they are sometimes accidentally pressed.

On the back of the smartphone there is an 8.7 MP camera with LED flash, an external speaker and contacts for connecting a case with built-in wireless charging.

Screen

Nokia Lumia 925 is equipped with a 4.5-inch AMOLED screen with a resolution of 768 by 1280 pixels. The brightness and color rendition of the picture are simply excellent, and given the possibility system settings warmth and richness of colors, the display will appeal to absolutely everyone. The black color on any AMOLED screen is truly black, and thanks to the good anti-glare coating, the screen is perfectly readable in bright sunny weather. At medium viewing angles, the picture begins to turn slightly blue, but this is not a technical flaw, but an effect created by the anti-reflective coating.

Multi-touch is capable of accepting up to 10 simultaneous touches and works even if your hands are wearing gloves.

System

The smartphone runs Windows Phone 8. As a customization from the manufacturer, there are exclusive applications HERE Suite, HERE Maps, HERE Drive+, HERE City Lens, Smart Camera, Nokia Panorama and Nokia Cinemagraph. In fact, the apps fill the Marketplace's gaps in the absence of apps like Google Maps or Instagram, here their role is played by HERE Maps and Nokia Cinemagraph, respectively.
The Smart Camera and Nokia Panorama applications perform their tasks perfectly; in the first case, they allow you to take excellent pictures in motion, and in the second, beautiful panoramas.


In terms of applications and games for Windows Phone, almost nothing has changed recently. Users still suffer from the lack of seemingly familiar applications such as Opera, Chrome, Instagram or Google Maps. If users on Android and iOS are already tired of playing Real Racing 3, then on WP 8 they will have to be content with only the second part of the game for now.

Performance

Nokia Lumia 925 runs on dual-core Qualcomm processor Snapdragon S4 Krait (MSM8960) with a clock frequency of 1.5 GHz and Adreno 225 graphics accelerator.

There are simply no games yet that can fully unleash the potential of the Windows Phone processor, so all games run on maximum settings graphics and with maximum FPS.
1 GB of RAM allows you to keep several open applications and work comfortably by switching between them.

Test results in various benchmarks:

  • Antutu Benchmark: 11231
  • Sunspider: 900 ms
  • MultiBench 2: 17.795 / 24.626 / 02.528 / 37.804
  • WP Bench: 225.25
  • Phone Mark: 940

Battery

The smartphone's battery has a capacity of 2000 mAh and is not removable. Since the methodology for testing the autonomy of Windows Phone smartphones in our laboratory has not yet been fully developed, we will present test results from the GSMArena portal.

In web surfing mode, the smartphone holds a battery charge for 5 hours, and in video viewing mode - 5 hours 48 minutes. For a smartphone with a 2000 mAh battery, the result is very modest. With Push notifications enabled, average load of phone calls and mobile internet, you will have to look for a charging outlet in the second half of the working day.

Camera

Nokia's passion for creating good cameras for smartphones is making itself felt. Perhaps one of the best cameras is installed here, equipped with certified optics from Carl Zeiss and PureView technology. The color balance in the photo is excellent and even in poor lighting the amount of noise is very moderate. Stabilization when shooting video is also excellent.

Communications and sensors

Lumia 925 supports work in mobile networks GSM 900/1800/1900, 3G and LTE (700, 800, 900, 1800, 2100, 2600 MHz).
Job Wi-Fi module caused some problems. Any Wi-Fi hotspot can work on one of 13 communication channels, this is done so that with a large number wireless networks in a small area, the signal from all points did not overlap, and they did not interfere with each other’s work. But, the Lumia 925 Wi-Fi receiver, for technical reasons, simply cannot see channels above 10, which is what happened in our case. Accordingly, you may simply be left without access to public networks operating on channels 11, 12 and 13, or you will be forced to configure your home router accordingly. In practice, Alexander Bobylev and I encountered this for the first time and were very surprised.

Bluetooth 3.0 operation wireless headsets did not raise any questions. NFC module worked normally.

Bottom line

Nokia has done an excellent job of correcting the mistakes made with the release of the Lumia 920 and released an excellent successor in the form of the Lumia 925. The use of aluminum and polycarbonate in the manufacture of the body has become good decision, and the smartphone received a very fashionable design. Nokia has always paid a lot of attention to the cameras that it installs on its devices, and the 925 was no exception. A wide range of photo applications and a good camera will allow you to take interesting and unusual pictures.

Unfortunately, with a fairly capacious battery, the device has very average battery life. It is also worth noting enough high heat devices during prolonged use, and this is observed not only when playing heavy 3D games, but also when normal viewing Internet.

There are a sufficient number of Windows Phone 8 lovers, as well as haters, so I will not attribute this to the pros or cons of the smartphone itself. Users decide for themselves which system they want to use.

Device price: 19,000 rub. / 4400 UAH.

Alternatives

HTC Windows Phone 8x- 13,000 rub. / 3000 UAH

Windows Phone 8x has the same hardware and the same performance as the Lumia 925. The smartphone's camera takes significantly lower quality photos. The device screen is only 0.2 inches smaller and is made using Super technology LCD 2, not AMOLED. The body of the device is made entirely of plastic, but has an equally attractive design. But it’s worth noting that HTC Windows Phone 8x costs almost 6,000 rubles. cheaper than Lumia 925.

Apple iPhone 5C 16Gb- 23,000 rub. / 4900 UAH.

Of course, it would be a little wrong to compare the performance of devices running on completely different platforms, but specifications smartphones are almost the same. The smartphone runs iOS, for which there are several times more applications. The iPhone 5C is a little inferior in terms of image quality, has a plastic body and costs 4,000 rubles. expensive.

Samsung Galaxy S4 mini Duos - 12,000 rub. / 3800 UAH.

Again, a smartphone that runs not on Windows Phone, but on Android. Galaxy S4 mini has a slightly more powerful processor and 512 MB more RAM. In addition, the smartphone has the ability to install maps microSD memory and support for two SIM cards. Both smartphones are equipped with AMOLED screens. The body is completely plastic, and the camera here is worse than on the Lumia 925, but the smartphone costs 7,000 rubles. cheaper.

The device is provided by Nokia.
