Modern smartphones surprise with their performance and capabilities. However, sometimes a time-tested model, which cannot be classified as a novelty, is quite enough to comfortably perform the necessary tasks. It is such a gadget whose characteristics we will consider in more detail.
Equipment
The smartphone is packed by the manufacturer in a cardboard box, on which there is practically no information. Most likely, this is the expression of Lenovo's minimalist style, emphasizing that this device is still the "younger brother" of the flagship smartphone at the time, Lenovo Vibe X.
For most buyers, it may be important that in addition to the charger, USB cable and documents, the manufacturer took care of the availability of starter kit wired headset. Although it looks simple and frankly cheap, the sound is quite pleasant and will appeal to most unassuming music lovers.
Appearance
The smartphone received a 4.7-inch display, but at the same time it looks quite large. This is due to the wide bezels around the screen, which cannot be definitely called a minus, but some users may not like them. Despite such dimensions, the gadget lies pleasantly in the hand and does not slip out of it.
The body is completely made of plastic, in places matte, and in some places with a metallized coating. The color of the case is light, pleasant, and with the right lighting, the effect of a golden sheen is also created. The device is assembled with high quality, there are no backlashes and squeaks. In general, the smartphone gives the impression of a well-thought-out model, albeit from the budget segment. Many Lenovo smartphones can boast of this feature, the prices for which remain in the range of 7-8 thousand rubles.
The back cover is removable; under it there are slots for SIM and memory cards. The Lenovo S650 battery is removable, which has become a rarity in most smartphones lately.
According to some reviews, the wear resistance of the body elements is quite high, and even with inaccurate use, the gadget will not lose its attractive appearance soon. The display provides protection against fingerprints, which could appear during operation and interfere with the comfortable viewing of photos and videos.
Display
We touched on the topic of coverage a bit, but now let's talk about the matrix. It, perhaps, can be safely called the weak side of this device, since it has a low resolution for a modern device, namely 960x540 pixels. With such parameters with a diagonal of 4.7 inches, pixelation becomes noticeable even with the naked eye, which is why the picture gets an unpleasant torn "ladder" structure, and the Lenovo C650's screen becomes more a minus than a plus.
Otherwise, the display performed well. Good color rendition, without emphasizing any particular color, rather large viewing angles, a sufficient margin of brightness for using the device even in sunny weather - all this can partially compensate low resolution display.
The sensor received the ability to perceive up to 5 touches at the same time, which is an ordinary indicator for state employees. But at the same time, there are no errors or sticking at all, so it can be confidently called good and of high quality.
"Iron" characteristics
The main processor is the SoC platform known to most budget models 2014-2015 years. It is a single-chip chip with a processor with four cores capable of developing frequencies up to 1.3 GHz and a Mali-450MP2 video accelerator. The crystal is made according to the 28 nanometer process technology, which provides a fairly low power consumption and low heating of the device when working with resource-intensive processes.
The processor works in conjunction with RAM volume of 1 GB. This is a little by modern standards, but quite enough for comfortable work with two to three lightweight applications at the same time. In order to unload the RAM to the maximum, the system is optimized by the manufacturer, as a result of which about 500 MB is always available to the user, the rest of the volume is occupied by system applications. It is worth noting that in some Lenovo models with the same amount of RAM, a problem arises during operation, since only a fifth of the RAM remains available to the user. Here "Lenovo S650", the characteristics of which often do not differ from problem models, undoubtedly wins.
The Antutu benchmark test shows a result of 17,000 rating points, which is comparable to such flagships of previous years as Htc one X and Samsung Galaxy S3, although Lenovo C650's characteristics seem less significant at first glance.
Smartphone communication capabilities
At present, a smartphone without 4G support is sometimes considered too outdated, but do not forget that the higher the communication standard, the greater the battery consumption. This model lacks support for 4G, but the mode of all frequencies and 3G standards is fully implemented, including HSUPA and HSDPA.
SIM cards are standard sized and do not need to be cut or changed to start using your smartphone. When making calls, according to tradition, one of them becomes inactive, since the device is equipped with only one radio module.
In addition to the cellular network radio module, the Lenovo C650 phone is equipped with Bluetooth 4.0 generation modules, as well as Wi-Fi with support for b / g / n protocols. If necessary, a smartphone can be turned into a portable Wi-Fi router in several stages. Check with your operator in advance if additional funds will be charged for this, as some companies have recently introduced a similar practice.
A smartphone is not complete without a GPS module. The signal strength of the satellites is quite reliable even in cloudy weather. When tested, in most cases it took about 1 minute, while the hot one took less than half a minute, or even a few seconds.
Memory
The internal non-volatile memory of the smartphone is not particularly pleasing with its size. It is a built-in 8 GB flash drive. Of this, about 3 GB are occupied system files... In total, a little less than 5 GB of disk space is available to the user out of the box.
To expand it, you can use microSD memory cards up to 32 GB, preferably class 10, in order to ensure maximum performance. According to reviews of users who tried to use memory cards of a larger volume, the smartphone simply refuses to see them, so when buying, you should rely on the manufacturer's stated limits. However, comparing prices for Lenovo smartphones, this model wins in terms of price / quality ratio, and you should think - perhaps this amount of memory will be quite enough.
Battery
The standard battery supplied with the smartphone received a rather ordinary volume of 2000 mAh. This is a small indicator in the modern world of battery-demanding gadgets, but for its modest characteristics this battery is more than enough.
The smartphone comes with Charger, capable of delivering power up to 1 A. At these rates, it takes about 2 hours to fully charge the battery.
According to reviews, one charge is quite enough for active use of the smartphone all day, this is noticed by users commenting on the Lenovo S650 w3bsit3-dns.com topic. However, at the same time, it will have to be connected to the power supply every night, which means that the battery charging / discharging cycles will be used up in about 2.5 years.
Main and front cameras
The Lenovo S650 w3bsit3-dns.com smartphone was developed at a time when software image interpolation was not yet in vogue, so the claimed photo resolution corresponds to the resolution of the camera matrix. For the main camera, it is 8 megapixels, while with the front camera, the situation is more sad - its indicator is only 0.3 megapixels, so you can forget about selfies. Considering the model the cameras are quite acceptable for its price segment.
The camera is quite decent for its level, in good lighting the pictures are rich and clear. However, using automatic tuning parameters when shooting, watch the result. Sometimes software makes mistakes with the choice of the mode, as a result of which the colors may be distorted, and highlights appear in the photo, or, conversely, too dark areas.
Front-camera can be used only for conversations using video messengers, but no more. You should not take pictures with her: you definitely cannot call them high-quality.
Smartphone setup
After taking it out of the box, the smartphone needs to be set up. In this, this model is no different from other Android devices. She has a set of service applications from Google on board, so it is recommended that you immediately get yourself account for comfortable use of a smartphone and data synchronization. The rest of the Lenovo C650 setting is intuitive. The smartphone has hints regarding the functions of the interface.
conclusions
The smartphone is solid and pleasant to use. It is suitable for those for whom communication is in the first place, and not entertainment. Of the minuses, we can only note the overheating of the processor under very long, heavy loads, not provided for this hardware, the weak display resolution, and the version of Android that is already beginning to become outdated. If this is unimportant to you, you can safely buy this model- otherwise it will not let you down. In addition, if necessary, repairing Lenovo C650 is quite cheap due to low prices for components, so an accidentally broken display will not be a tragedy.
Remembering the smartphones with which we met in 2013, we can safely say that it passed under the sign of MediaTek chipsets. Thanks to the MT6572 and MT6589, many manufacturers have created successful solutions with an excellent price / performance ratio. The Lenovo S650 smartphone appeared on our market at the end of 2013, it can be classified as a next generation device, because it is built on the new MediaTek MT6582 platform. The model boasts not only updated hardware, but also new software. Let's get to know him better and find out what the innovations are.
Contents of delivery
Lenovo S650 comes in a cardboard box with a manufacturer-specific design. In it you will find: a smartphone, a charger with an output current of 1 A, a USB cable, a simple in-ear headset, a functional stand case and a minimum of related documentation.
Design and ergonomics
The Lenovo S650 case is completely made of plastic. The central part of the front panel is occupied by a screen with rather wide frames, under which the touch keys "Menu", "Home" and "Back" are located. Above it - the manufacturer's logo, front camera and earpiece mesh, in the left corner of which is hidden a light indicator. Long hold "Menu" calls up the list of the last running applications, "Home" - launches the Google Now assistant. On the rounded sidewalls, there are two separate volume buttons (on the right), a microphone hole with an interface connector (below), a power button and a mini-jack (on top). The listed elements are located on a thin glossy frame that expands towards the bottom of the case and extends over the back of the smartphone. The main camera lens and LED cover can be seen here. After removing the cover and taking out the battery, we get access to two slots for Mini-SIM-cards and a memory card.
Various types of plastic are used - the sides and buttons are glossy and slightly slippery, the lid is more matte, with small perpendicular notches. When bright artificial lighting pearlescent blotches are visible, shimmering in the light. In addition to the black and silver variant we reviewed, the Lenovo S650 is available in white.
The build of the smartphone is not bad. Under strong squeezing, the case does not creak, but it lacks rigidity - it lends itself to slight bending, which can cause the lower lid latches to come off. At 138x8.8x69.8mm, it weighs just 126 grams and feels lighter than you'd expect. The small thickness and rounded edges allow the Lenovo S650 to fit comfortably in the hand, but the physical buttons spoil the ergonomics. They are thin, protrude slightly above the body, relatively tight, with a short stroke and, moreover, are made of the same plastic as the sidewalls. People with small palms will find it difficult to reach the power key, which is located in the center of the upper edge, and the included case further reduces the convenience of using the volume keys. This could completely spoil the impression of the ergonomics of the smartphone, if not for some tweaks. Firstly, in the settings, you can activate the ability to turn on the screen with the volume keys, and secondly, you can lock the screen by shaking the smartphone strongly in your hands.
The complete case provides not only protection, but also additional functionality. The base of glossy mother-of-pearl plastic protects the ends and rises above the surface of the screen, preventing it from touching the table surface. The rubber insert on the back contains a metal plate so it can be bent. In this position, the cover acts as a stand.
Screen
The Lenovo S650 has a 4.7-inch IPS display with a resolution of 960 by 540 pixels. Its minimum brightness is 60 cd / m2, average - 249 cd / m2, maximum - 484 cd / m2. The minimum brightness is too high, it can be reduced by using third-party applications, for example, Lux Lite. The maximum brightness level ensures good readability outdoors in sunny weather. Judging by the photographs of the display on the street, we can conclude that it is not an OGS screen, although the air gap is extremely small.
Automatic brightness control exposes a sufficiently high brightness in all lighting conditions. During normal use, there are no complaints about the screen, it looks quite high quality. Lively, saturated colors, oleophobic coating, thanks to which the finger glides perfectly on the glass, and the screen itself practically does not collect fingerprints. The disadvantages include only not the highest resolution by modern standards. In a smartphone of the end of 2013, with such a diagonal, I would like to see a full HD screen. However, even at qHD resolution, the picture does not look grainy.
Factory Calibration Check Confirms Decent Display Quality on Lenovo S650
Interface
Lenovo S650 runs an operating room Android systems version 4.2.2. As in previous smartphones, the company uses its own graphical shell, which changes the appearance of the system beyond recognition. In Lenovo P780, S820, S920, which we got acquainted with earlier, Lenovo Launcher of the second version was installed, in S650 - the third. Adding one to ordinal number version, the shell has acquired new functionality.
The key feature is that support for themes remains in place. In the "Theme Center" you can choose one of several predefined themes that change the appearance of the icons standard applications, wallpaper, lock screen, start-up animation and color scheme of some built-in applications. Each of these parameters can be customized individually by assembling your own theme from the "pieces".
There are settings for changing the animation of paging desktops, enabling cyclic scrolling, the ability to back up settings. There is also support for gestures. They are less "advanced" than in third-party launchers such as Nova, allowing you to bring up the notification bar or list latest applications in one motion.
As before, the settings menu is divided into three tabs.
But these are all little things. The main change is that the shell has abandoned the usual application menu. Now all installed programs immediately go to the desktops, of which there can be up to 18, and it is proposed to sort them by folders.
The notification shade contains a row of ten scrollable shortcuts for rapid change parameters, the second tab contains 15 such switches. You can change their order at your own discretion. A simple press on them leads to a state change or mode switch, holding it takes you to the corresponding settings menu. You can activate minimizing the panel after clicking on the switch.
Some of the functionality is familiar from solutions from other manufacturers. Regarding the design of folders, animation of their opening and the appearance of the menu of recent applications - they repeat the solutions MIUI firmware... In the menu of the last running applications, you can clear the RAM by closing the running programs. By pulling the application icon down in its left corner a "lock" will appear - this means that it will work even after clearing the RAM, by moving the icon up you will close the application.
Interaction with the shell is as follows. To create a folder, you need to drag the icon of one application to another. Going into a folder, you can "pull" a shortcut from it, the folder will exist as long as there is at least one program in it. A pinch to the center brings up a menu with desktop windows. Here you can change their number, swap them and assign the main screen. Swiping up from the bottom of the screen, a list of widgets appears, from where they can be brought to the desired desktop.
In general, Lenovo's new skin has become more functional, while the number of possible settings has decreased. She looks more beautiful and complete. Although many of the "chips" are familiar from other shells and third-party firmware, it can be argued that the best solutions were copied.
It should be noted that initially the smartphone contains a large number of preinstalled apps Yandex, clients to access social networks... Some of them duplicate the functionality of Google programs. Fortunately, most of them can be removed. There is also Lenovo apps: SHAREit - to share various content with friends, SECUREit antivirus, SYNCit - to create cloud backups contacts, programs.
Calls and multimedia
Support for two SIM-cards is implemented on the basis of one radio module - during a conversation on one card, the second is disabled. The settings provide the ability to set separate ringtones and notifications for them, as well as default parameters - with which of them it is preferable to send SMS, make calls, transfer data. Most similar smartphones when you open the "Messages" and "Calls" application, a switch appears in the status bar that allows you to quickly change the selected SIM card before performing an action. In the case of Lenovo S650, the notification is also present, but it takes you to the appropriate settings item. Therefore, if you use both cards equally often, it is better to select the "Always ask" item in the settings from which card to call or send messages - in this case, the corresponding applications will have two call and SMS buttons.
The hardware part, which is responsible for voice communications, is implemented averagely. The ringing loudspeaker is moderately loud, but its sound is absolutely flat, the vibration alert is weak, it is easy to miss it. The quality of the microphone and earpiece is average. During testing, several times there were complaints about poor audibility when talking in a noisy environment. The loudspeaker volume is enough for a conversation in a quiet environment, if it is noisy around, then the interlocutor is practically inaudible.
Multimedia capabilities are implemented at the proper level. The smartphone plays Full HD video at 60 frames / s, but the built-in player has not yet learned how to play AC3 audio tracks. Music playback quality is at good level... Lack of noise, high volume and generally pleasant sound will not disappoint music lovers.

Performance and memory
Lenovo S650 is based on SoC MediaTek MT6582. Like previous solutions, it is manufactured using the 28 nm process technology, includes four Cortex-A7 cores operating at 1.3 GHz and a dual-core GPU Mali-400 MP2. The amount of RAM is 1 GB, built-in - 8 GB (5.62 GB available), there is a slot for memory cards.
There are no performance issues. Scrolling desktops and animations are smooth, applications launch quickly. Heavy games are in progress, for example, Real Racing 3 sets the maximum graphics settings, the frame rate is sufficient for a comfortable game. The only nitpick is the amount of RAM. With a small set installed programs after downloading the smartphone, about 400 MB are free, while working with several applications, about 150 MB remain free. Obviously, a custom shell requires a few more resources than a standard one. When working with heavy applications, it is sometimes unloaded from memory. It turns out that 1 GB is enough "end-to-end", and the extra 500 MB would definitely not hurt.
The work of GPS and Wi-Fi is not satisfactory. A “cold start” takes less than a minute, the subsequent search for satellites is much faster. The speed of data exchange via Wi-Fi is maximum.
Camera
The smartphone has two cameras: a front one with a resolution of 0.3 megapixels and a main one with 8 megapixels with autofocus. The front camera does not shine with the quality of the picture and will provide a picture acceptable for communication in Skype, you should not expect more from it. The main one demonstrates a consistently good quality of photo and video, both when shooting indoors and when shooting outdoors. Pictures are obtained with natural color reproduction and relatively detailed. V normal mode the camera shoots at an average speed, but creating HDR photos will require 3-4 seconds of waiting and a static scene, since moving objects are blurred.
Sample photos taken with Lenovo S650 smartphone
An example of a Full HD video captured by a Lenovo S650 smartphone
The camera app is a highly simplified "Supercamera" that we saw in the Lenovo P780. The general interface is similar, but as soon as you go into the settings, you will see the standard for most Chinese smartphones menu.
Autonomy
The Lenovo S650 is powered by a removable 2000 mAh battery. In standby mode, the smartphone is discharged slightly, like most other models based on MediaTek chipsets. But as soon as you turn on the screen and start doing something, the charge begins to melt before our eyes. In the author's typical mode of use, with all communication modules turned on, with a small number of calls, reading Twitter feed and articles throughout the day, synchronizing one Google account, and listening to music for an hour or two, the charge is enough for a daylight work - filmed at 8 am from charging, the smartphone will show about 20% of the charge by night and will ask for a power outlet. Already, many smartphones of different price categories able to hold out in this mode for two days.
You can improve the big picture a little bit by using the Power Manager app. In it you can create power profiles, configure the operation of all communication modules, display, background applications, etc. By independently adjusting the power consumption and sacrificing the full-fledged operation of the smartphone, you can “squeeze out” two days of work, but it is better to count on a day of work, and if you actively use various functions, you will need to charge before you get home.

Outcomes
Lenovo S650 can be called one of the most controversial smartphones from the company that we have had to meet recently. On the one hand, it has a relatively unique design and its own face, but you don't feel the "thing" in your hand. The poor location of the power key smooths out the ability to lock the screen by shaking the smartphone and turning it on with the volume buttons. The high-quality bright screen is accompanied by mediocre autonomy and a quiet earpiece. A beautiful and functional shell is able to fall in love with this smartphone, but what to do with the rest of the shortcomings? Roughly speaking, for every bold "plus" here you can find several cons. In such a situation, the price of a smartphone plays an important role. At the time of this writing, large online stores sell the model for 2,499 hryvnia, and many small ones ask for it from 1800 hryvnia with a "store guarantee", which is a typical picture for Lenovo smartphones. Where and on what terms to buy the S650 is everyone's personal business, but do not forget about the existence of solutions from other brands, which will surely allow you to get a less controversial experience.
Notify when on sale
The lenovo s650 smartphone does not act as a "poor" version of the android device. This is quite an advanced device designed for comfortable use. Buyers were invited to evaluate not only the attractive appearance and good performance, but also find something more interesting in it. Although, the model also has certain disadvantages. What are the main features of a smartphone presented by a world-famous manufacturer?
External data
The phone case is made entirely of plastic. In the center of the front panel there is a display, which has a fairly wide frame with touch buttons located under it. In the upper part, as usual, there is a company logo, a front camera module and an earpiece.
The side faces accommodate two separate buttons, the task of which is to adjust the volume. There is also a microphone hole, a power button.
It is easy to find the main camera on the back panel. Removing the cover opens access to the battery and two SIM card slots. The build of the phone is good. If you squeeze the device, its body does not emit squeaks and other extraneous sounds. True, there is a little lack of rigidity, as a result of which the latches located at the bottom sometimes move away. One cannot fail to note one more important feature. The back panel of the smartphone is laser processed, so it is pleasant to the touch and creates comfort when using the device. In addition, it is also additional protection from fingerprints and scratches, which preserves the attractive appearance of the device.
Equipment
The box in which the lenovo s650 smartphone is shipped contains the device itself, a battery, a charger, a microUSB cable, documentation and headphones. It is quite such a standard set, but it is worth noting that some Lenovo models cannot boast of such a set.

Camera
The main camera module, which the lenovo s650 phone has, is 8 megapixels, it is equipped with autofocus. It is quite enough for creating high-quality images. With the main camera, you can shoot outdoors or indoors. The photos are acceptable, the color rendition is good. But to create HDR images, you have to wait a few seconds, otherwise the objects will be blurry. The front camera has only 0.3 megapixels, from which it is easy to conclude that it does not shine with image quality. But it is able to provide a decent picture when making calls via Skype.
Display
The screen with a diagonal of 4.7 inches is able to provide acceptable readability in bright sunny weather, subject to maximum brightness. If necessary, its level can be reduced. The air gap is small, as evidenced by photographs taken when shooting outdoors. In general, the display is pretty standard, it does not stand out in any way from many other models presented by Lenovo.
In terms of performance, there are no problems. Scrolling through desktops and animations is quick and fluid. Applications start quickly, without delays. It is even possible to run some heavy games. The disadvantage is the amount of memory. If you set all required programs, the user will have about 400 MB, and if simultaneously work with several applications, even less - only 150 MB. Thus, the amount of memory provided "end-to-end". If the manufacturer had provided an additional 500 MB, they certainly would not have been superfluous.
Autonomous work
The lenovo s650 smartphone is equipped with a removable 200 mAh battery. When the phone is in standby mode, its charge decreases slowly, similar to other modifications created on the MediaTek chipsets. However, when you turn on the screen, as well as manipulate the device, the charge literally melts before our eyes. If you use the phone in a normal user mode, which is suitable for a modern person, the device will last only one day. Even if in the morning the smartphone is only removed from the socket with a full charge, literally by the evening it will ask to be returned. This is a serious drawback, especially considering that most modern devices can already hold out for two days in a similar mode.
What is the conclusion from all of the above? The Lenovo s650 phone is one of the most controversial models. If you consider its features from the one hand, it has a unique design. Despite this, the real "thing" does not feel in the hand. Of course, the placement of the buttons is unfortunate, but this unpleasant moment is smoothed out by the ability to lock the screen by simply shaking the phone. A high-quality screen is an advantage, but the overall impression is overshadowed by a rather mediocre battery life and a quiet speaker designed for talking.
Of course, an attractive appearance is able to fall in love with oneself at first sight, but it is difficult to argue with other shortcomings. In general, each advantage is opposed by several disadvantages, and quite significant ones. The cost of the phone is also of great importance. It is pretty decent, despite the flaws in the device. Should you buy this model? No one will give an answer to this question, since buying a smartphone is everyone's personal business.
