For Lenovo, 2014 was a very productive year. The lineup has been expanded to include both budget devices and powerful smartphones. One of the new products presented was the S660 model.

Design

The Lenovo S660 phone is a fairly compact device. The size of the device is slightly smaller than usual due to the 4.7-inch screen. A slight reduction in the diagonal made it possible to make a gadget that is comfortable to use. The user can operate the device even with one hand.

The material of the case has undergone fundamental changes. In Lenovo S660, plastic has been replaced by aluminum. This solution significantly increased the smartphone's resistance to scratches and dents. Of course, if you want to, it’s not difficult to damage the device, but metal saves you from accidental injuries.

Such an interesting case material also has its drawbacks. The surface of the smartphone collects fingerprints incredibly quickly. Naturally, wiping your phone is not difficult, but it is unpleasant.

Due to the metal, the device looks solid and quite stylish. Although there are no significant changes in appearance, there is definitely some zest in the device.

The front side houses the display, sensors, camera, speaker, touch buttons and logo. On the right side there is a volume control and a power button. The back side has a logo, main camera, speaker, flash and microphone. The top end became a shelter for the headphone jack, and the bottom was reserved for USB.

In general, the device has an interesting appearance. The build quality is not satisfactory, and the durability of the device is excellent. Quite a suitable design for an entertainment smartphone.

Display

The C660 was equipped with a screen of only 4.7 inches. Quite a strange decision for a company that equips even budget devices with a large size. Low resolution will also be an unpleasant fact. The Lenovo S660 smartphone has only 960 by 540 pixels. This is an incredibly low specification and is more suitable for phones with four inches. Accordingly, the pixels are visible even to the naked eye.

The IPS matrix of the smartphone brightens up the situation somewhat. The screen on the Lenovo S660 is quite bright, which ensures high-quality work in the sun. There are also manual and automatic display settings. In addition to brightness, the device boasts a high viewing angle.

Despite the entertaining direction of the series, this representative did not have the best screen parameters. In terms of characteristics, even budget representatives of category “A” beat the C660.

That's what the manufacturer took care of protecting the display. The device is equipped with glass. There is no need to worry about scratches and damage to the screen.

Camera

The Lenovo S660 received the usual 8 megapixels for inexpensive models. The camera, which is acceptable for a budget employee, looks rather strange in a more expensive series. The resolution of 3264 by 2448 also worsens the impression. All characteristics indicate average image quality, but things are much worse.

In fact, the device takes photos that are more likely to be expected from a five-megapixel camera. The device lacks sharpness, but there is too much noise. Setting up the Lenovo C660 will not solve the problem either. The user will have to forget about night photos, since the pictures turn out incredibly bad.

A similar situation happened with video recording. The filming takes place in HD quality, but the result is disappointing. The video camera has the same problems as the photo camera.

The poor implementation of the main camera does not give hope for the front camera. The phone has a peephole of only 0.3 megapixels and is only suitable for video calls. You shouldn't expect more from the front camera.

Filling

The strongest point of the Lenovo S660 is its hardware. The company equipped the phone with the MTK processor common to the Chinese. Naturally, Snapdragon would be a better choice for an advanced model, but the Chinese took the path of saving. The processor has four cores, each of which operates at a frequency of 1.3 GHz.

Although there is no doubt about the performance of the filling, similar parameters are present in many of the company’s state employees. There is a feeling that the “S660” is not in its series.

The smartphone has a gigabyte of RAM. This amount of memory is quite enough to maximize the potential of the device. The combined efforts of the RAM and processor allow the C660 to easily solve a lot of problems.

Another parameter will not particularly please owners of the Lenovo S660. We are talking about 8 GB of native memory. Unfortunately, the user will only be able to use 6 GB. The remaining memory is allocated for Android. You can increase the memory with a 32 GB card.

Battery

Since the device belongs to the “S” entertainment series, the battery is installed accordingly. The battery capacity is 3000 maH, which is quite enough for long-term operation.

Active use of the gadget will drain the charge in about 6-7 hours. Quite good for functionality. Adjusting the screen brightness and disabling unnecessary processes will significantly increase the operating time.

The smartphone does not suffer from a lack of battery capacity; this is facilitated by the economical filling. Most of the charge will be spent solely on the display.

System

The device runs under the now outdated Android 4.2.2. The system has the design of the company Vibe UI with installed applications. Some programs will come in handy. If the question arises of how to take a screenshot on Lenovo S660, additional applications will help.

There are also more modern versions of the system for the C660. You can update Android using either FOTA or

Sound

You can't expect any special frills from the speaker. The sound for a device running on Android is quite acceptable and does not cause negativity. The included headset is not good for almost anything. The user will be forced to change headphones to get high-quality sound.

Connection

The device works with 2G and 3G, and the connection quality is quite high. The device also supports 2 SIM cards. Unfortunately, when making calls, one of the cards is disabled, since the smartphone only has one radio module.

The phone supports Wi-Fi, Bluetooth and GPS functions. Unfortunately, the phone does not have OTG.

Price

You can become the owner of a “C660” for approximately 9 thousand rubles. Considering the characteristics of the device, the price is definitely too high. Some representatives from the “A” series have brighter parameters and lower cost.

Negative reviews

The most painful place of the device is its display, and many people note this. Conspicuous pixels definitely do not improve the user's mood. Despite the IPS matrix, the more important characteristics are not encouraging.

A weak camera is another drawback of the phone that buyers point out. Even under ideal conditions and great efforts of the owner, the picture can turn out bad. The reason for this, naturally, is the low resolution and 8 megapixel cameras. Solutions such as setting up the Lenovo S660 will not bring much results.

An out-of-date version of the system is also not a pleasant thing. The need for an update confuses a lot of users. Without experience in firmware, it will be difficult to update the device.

Positive reviews

The advantage of the C660 is its productive hardware. The phone is really powerful and can handle even demanding games, gamers appreciate it. The problem will occur in 3D applications, but reducing the quality will solve the problem.

It is worth paying tribute to the stunning appearance. In addition to the fact that the phone is well-built, the device has a stylish design that is appreciated by the owners.

The autonomy of the device is the main feature of the series. The capacitive battery allows you not to worry about the state of charge.

Bottom line

The smartphone turned out to be not the most successful. In a detailed comparison, the S660 device is inferior even to some Lenovo budget phones in terms of characteristics and cost. A bunch of shortcomings, as well as an inflated price, do not create much attractiveness.

The hero of today's review, the Lenovo S660 smartphone, has many similarities with other company smartphones. Technical characteristics and equipment are reminiscent of the model, and the large battery and the use of metal body elements are reminiscent of the P780 and models. At the same time, we can say with complete confidence that it has its own “face” and will not get lost in the close ranks of Lenovo smartphones. We won’t bore you, but we’ll just tell you what we liked and didn’t like about this device.

Equipment

In it you will find: a smartphone, a charger unit with an output current of 1.5 A, a cable, a simple headset, the necessary minimum documentation and a case. Let's look at it in more detail.

What we have here is a typical cover-cover for the back of a smartphone, the main feature of which is a cutout in the back, into which a metal plate covered in rubber is inserted. The metal is springy and bends in a semicircle, which allows you to use the case as a stand, fixing your smartphone in a horizontal or vertical position. A similar case comes with the Lenovo S650, only this time the manufacturer used dark blue matte plastic.

Design and ergonomics

From the front, the Lenovo S660 looks like any other mid-size smartphone. Accessories for Lenovo smartphones display a logo and touch keys with a characteristic pattern and backlighting that lights up when touched. Other elements here include a thin speaker grille, a window for proximity and light sensors, a camera lens, and an indicator for missed events. When viewed from the right angle, it shines too brightly, but when the smartphone is lying on the table at a short distance from you, its blinking is simply quite noticeable.

The smartphone is framed by a strip of plastic interspersed with sparkles. Physical control keys are located on the right: volume and lock keys. The volume button this time really resembles a rocker - its middle is slightly sunken, and the edges are raised, it can be easily felt blindly, and is convenient to use. The power key, on the contrary, is slightly rounded towards the body, which does not significantly worsen its ergonomics. Audio and interface connectors are located on the left side of the top and bottom edges, respectively.

The back cover is made of a single piece of metal, a glossy logo is engraved on it, and there are slots for the camera, flash, second microphone and ringing speaker grille. Under the cover there is a removable battery and slots for a memory card and two Mini-SIMs, located one above the other. Replacing them will require removing the battery.

A collapsible body with metal elements is not the easiest design task. However, among the smartphones of the last five years, we can recall several examples of its successful solution - for example, Samsung Wave, Wave 3 and Captivate had different, but quite successful and reliable cover designs. Lenovo decided to go their own way and designed the cover similarly to plastic ones - it is a plate with small latches around the perimeter. Plastic is more flexible, so these covers can be easily removed and replaced. With the Lenovo S660, everything is more complicated: to remove the cover correctly, you need to pry it off with your fingernail, then swipe it right and left, gradually releasing the latches. Intuitively, you just want to pull the cover towards you, which can easily damage the plastic grooves. Of course, removal instructions are in the documentation, which no one reads, and on the inside of the cover, but a sticker on the body would also be nice. Because of all of the above, the cover does not sit very tightly in its place, there are no sealing stickers on it, it bends a little towards the battery and has some play at the bottom. All this is invisible in the case, but because of it, not the thinnest smartphone becomes even thicker.

Perhaps the strange cover is the main disadvantage of the device’s design. Otherwise, it fits comfortably in the hand, the metal and weight feel quite pleasant in the hand.

Operating system and shell

One of the advantages of using skins as pure Android is the same user experience. In Fly smartphones you can always see “pure” Android, in Samsung and LG – TouchWiz and Optimus UI shells, which have almost the same appearance and functionality on devices of different price categories. At Lenovo, until recently, everything was exactly the same. But in the S660, about 30% of the shell consists of the Lenovo launcher, the rest is pure “robot”. Many of the usual Lenovo applications, such as the energy manager, are missing. Thus, the lock screen, notification line, camera and settings menu are standard, and the desktop on which all installed applications are located is from Lenovo.

The desktops retain the usual functionality: support for themes, customization of animation, circular paging and support for gestures (for example, by swiping down on the desktop, you can open the notification line, up - a list of recently running applications).

This list can be presented in two forms: if you hold the “Menu” key for a long time, a standard list for the operating system opens, if you use a gesture, a stripped-down version from the Lenovo shell opens.

All this beauty, literally “stretched” on Android 4.2.2, is perceived too negatively and raises questions, especially when you know that Lenovo Launcher (or Vibe OS) is a beautiful and functional shell, especially since hardware similar to Lenovo is already on the market An S650 that makes everything look the part. We can only hope that this misunderstanding will be corrected in the latest firmware.

Hardware platform

The “heart” of the smartphone is the MediaTek MT6582 SoC - four Cortex-A7 cores operating at 1.3 GHz, plus a Mali-400 MP2 GPU. The amount of RAM is 1 GB, of which about 700 MB remain free, internal memory is 8 GB, of which 5.59 GB is allocated for user data. You can install a memory card and use it as your default storage.

The platform's capabilities are sufficient for smoothly scrolling through desktops, for most modern games, and for playing high-definition videos. In everyday life, there are no problems with performance; it is at a normal level, typical for most smartphones in the mid-price segment.

The operation of the Wi-Fi and GPS modules is satisfactory; they are sufficiently sensitive and work quickly.

Multimedia functions are implemented in the smartphone at an average level. The set of test videos traditionally does not play AC3 sound and for some reason there was no picture in the ParallelUniverse.avi video, including in the omnivorous MX Video Player. When playing music on headphones, the sound quality is good, slightly above the average level of devices based on MediaTek chipsets, and the volume is high.

Playing video files:

Telephone functionality is implemented at the proper level - the volume of the ringing and conversational speakers is sufficient in most situations, the vibration alert is average in strength and is not always felt. You can record conversations from the line using standard means; the speakerphone works fine. The operation of two SIM cards is implemented as standard - you can set the parameters of their operation in the settings, and then quickly change them using the switches in the notification shade. You cannot assign separate ringtones and messages to different cards.

The smartphone is powered by a 3000 mAh battery. This is noticeably less than that of the record holders - their batteries have a capacity of 4 Amperes and higher, but more than the average 2000-2500 mAh for devices with a screen diagonal of up to five inches. In Antutu Tester, Lenovo S660 shows a decent result at 760 points, but in other tests of autonomy the results are slightly less than expected.

In standby mode, the smartphone practically does not discharge. You can expect it to last about two days under medium load and about three days under light load.

In reading mode, all wireless communications are disabled, including data transmission on the mobile network, and the display brightness is set to 200 cd/m2. When listening to music, automatic data synchronization and data transfer worked. The sound volume in the headphones is at 12 out of 15 possible levels. All music files are in MP3 format, bitrate 320 Kbps. Navigation includes getting directions in the Google Navigation app. The brightness is set to 200 cd/m2, all data communication modules are disabled. When playing a video, data transfer is active on the mobile network, the display brightness is set to 200 cd/m2, the sound volume in the headphones is at level 12 out of a possible 15. The video file format is MKV, resolution 1024x432 pixels, frame rate 24. Playing video from Youtube was accompanied not only by work in Wi-Fi networks, but also active data transmission. The display brightness is set to 200 cd/m2, the sound volume in the headphones is set to 12 out of 15 possible levels.

Display

The Lenovo S660 has a 4.7-inch diagonal IPS matrix with a resolution of 960x540 pixels, there is no air gap. The minimum screen brightness is 9.6 cd/m2, 25% brightness corresponds to 120.4 cd/m2, 40% - 200 cd/m2, 50% - 234.6 cd/m2, 75% - 351.1 cd/m2, 100% - 460.7 cd/m2. Contrast – 1:606. In terms of brightness adjustment range, the screen looks quite decent. Checking the quality of the factory calibration showed that the matrix used is of good quality; its color temperature is raised to 7500 K.

In real life, the screen looks good - the picture is bright and smooth, pleasing to the eye, viewing angles are high, it is easy to read in the sun, and it is comfortable to work with the smartphone in the dark. The only noticeable drawback is the lack of an oleophobic coating, which is why the glass quickly becomes covered with fingerprints, which are difficult to remove.

Cameras

The smartphone has two cameras – the main one with a resolution of 8 megapixels with autofocus and flash, and the front one with a resolution of 0.3 megapixels.

The main camera is capable of taking good pictures in natural light, but noticeably suffers when there is little light. FullHD video is of average quality, but the front camera is present purely nominally; cameras of similar quality are found in most budget smartphones costing 1,500 hryvnia.

Results

As a result, the Lenovo S660 turned out to be a smartphone not without its shortcomings. The relatively critical ones are the design of the cover and the quality of the front camera, and the rest, we hope, will be eliminated in more recent firmware. At the same time, the smartphone performed quite well in everyday use and is a pleasure to use. The very fact of having a metal cover, a good screen and a high-capacity battery is captivating; in this case, the overpayment looks reasonable. If the Lenovo S650 is more of a women's smartphone, it can already be seen in the hands of many girls, then the Lenovo S660 is well suited for a man who needs a strict-looking smartphone with a screen diagonal of less than five inches to solve simple tasks.

Good day to all Trashbox readers. Today I got my hands on the Lenovo S660 smartphone. At the moment, this Chinese company ranks first among the largest manufacturers of personal computers in the world. But Lenovo doesn't live by PCs alone. The company produces laptops, netbooks, monitors, video cards, various PC accessories, bags and cases, and finally mobile phones. Plus, the products are accompanied by proprietary software. Equally important, quantity matches quality. But let’s not get distracted, because we have in our hands a dual-SIM smartphone Lenovo S660, which is waiting for its review.

So you can put the device on the table and watch a movie in peace.

The headphones aren't the worst. The first week, before purchasing a normal headset, they can serve.

Appearance and ease of use

The design is standard. Looks almost the same as all Lenovo devices. The smartphone comes in only one color - titanium.

Screen size – 4.7 inches. The phone has quite compact dimensions, which allows it to fit well in the hand, and if you use a standard case, it even sits tightly in your hand ;-).

The front panel is made of plastic, but there is an aluminum edging around it, which typically protrudes above the screen by 1.5 millimeters, which protects the screen from scratches when the smartphone is lying face down. Of course, for additional protection it would not hurt to buy a protective film.

Colorless touch function buttons are located below the screen. They have a backlight, which often turns on after you find the one you need. The buttons are far enough away from the side edges to prevent accidental activation when using the device.

The earpiece is located above the screen, to the right of it is the front 0.3 MP camera, and to the left are proximity and light sensors.

On the top edge of the device there is a 3.5 mm jack for connecting a headset, and on the bottom there is a microUSB port. At the bottom of the phone on the edge you can see a small hole for a conversational microphone.

The volume rocker and lock button are located on the right side of the device. The location is quite convenient, the buttons lie right under your fingers.

The back panel is metal. There is a speaker at the bottom of the rear panel. At the top there is an LED flash and an 8 MP camera. Below the camera and flash is the Lenovo logo.

If you open the back cover, you can see a 3000 mAh battery, two slots for installing SIM cards and a slot for a microSD memory card. By the way, the SIM card slots are located one below the other.

Screen

The color rendition is decent. At maximum viewing angles, colors do not fade or change shade. On a bright sunny day you can use your smartphone, the maximum brightness level allows. The minimum brightness level is also fairly well balanced. Auto brightness adjustment is smooth and adequate.

The smartphone does not have an oleophobic coating, so fingerprints will accumulate abundantly on the screen. Multi-touch works well, responds clearly and quickly, and recognizes up to five simultaneous presses.

System

For inexperienced users, this will be very unusual, because such an interface cannot be found except on Xiaomi. There are also proprietary applications: Lenovo SHAREit, Lenovo SECUREit, Lenovo SYNCit, Lenovo Weather. Weather, synchronization with the computer, antivirus - nothing original.

The firmware is OTA-updateable, so you can easily update via Wi-Fi with the click of a button. The settings section is slightly changed in appearance, but has the most standard set of functions.

Performance

The smartphone accepted the usual toys for our tests, Real Racing 3 and Dead Trigger 2, with maximum quality settings without slowdowns or lack of FPS. Taking into account the average screen resolution (540x960), the power reserve is enough to easily cope with any games in the next one and a half to two years.

Test results in various benchmarks:

• Antutu Benchmark 5.1: 20544
• Quadrant 2.1.1: 5529
• RL Benchmark SQL 1.3: 29.468 sec
• BenchmarkPi 1.11: 326 ms
• Linpack 1.2.8: 240.609 MFlops

Autonomy

In our proprietary test, the smartphone holds a charge in Wi-Fi surfing mode for 9 hours and 46 minutes. The result is very acceptable; with active use, the battery charge will surely last for 2 days.

Camera

During its existence in the mobile device market, Lenovo has established itself as a manufacturer of high-quality and inexpensive devices that perform well in everyday work conditions. Today, the company’s line of budget smartphones has a sufficient number of solutions for various fields of activity and despite the fact that The models are mostly similar to each other, each smartphone is unique in its own way. Lenovo S660, whose release date is February 2014, fully corresponds to this description.

Specifications

Options and packaging

The box in which the device is supplied is nothing special - an ordinary box made of hard cardboard, familiar to other phones in the series. But about the configuration it’s worth saying a little more.

The Lenovo S660 comes with the following:

• smartphone;
• Charger;
• in-ear headphones with microphone;
• instructions and other documentation;
• case for the back cover.

Lenovo S660 standard package

Will be useful

The case is a rather original design solution that combines a neat appearance and good ergonomics, expanding the range of capabilities of the smartphone during long-term use. The main feature of this accessory, which distinguishes it from other “bumpers”, is a cutout in the back, from which emerges a bendable plate made of metal and silicone. It serves as a stand and with its help the gadget can be fixed in the required position on any hard surface, which makes it possible to simplify some tasks - for example, watching a movie or shooting video from a certain angle.

Appearance and design

Externally, this gadget is not much different from other Lenovo smartphones, as well as from most devices in the budget segment.

On the front panel, in addition to the 4.7-inch display, there is the company logo, earpiece, front camera, various sensors and indicators; Below the screen are branded touch keys.

The back, made of high-quality aluminum, looks quite solid. This decision, however, had a negative impact on the convenience and safety of disassembling the phone - if it is necessary to replace the SIM card or battery, the user will have to, as they say, “sweat.” The problem can be solved by studying the instructions for use, in which you can find a detailed description of the procedure if you need to remove the back cover.

At the back there is a camera module, an LED flash and a Lenovo logo recessed into the body, as well as a main speaker and a microphone for noise reduction.

The smartphone adheres to Lenovo's signature minimalistic style

The top, bottom and side edges of the smartphone are reserved for the main controls and connectors. The lock key and volume rocker are located on the right side, the headphone jack is on the top, and the Micro-USB port is on the left side of the bottom.

note

Display

This smartphone has only one color option – Titanium. This is even good, because in silver the metal part looks the most impressive and presentable. The Lenovo S660 display is made using standard technology.

Its diagonal is 4.7 inches, resolution – QHD.

Having become familiar to the entire budget segment of the mobile device market, however, in this case it is distinguished by high quality color reproduction and a balanced, albeit slightly high, color temperature.

In actual use, the smartphone screen holds up well, regardless of weather conditions and lighting. In the sun it does not fade or fade, and in the dark at the minimum brightness level it does not hurt the eyes. There is no oleophobic coating here - fingerprints and stains will certainly remain on the screen, but this problem can be solved simply - just stick a protective glass on the screen or regularly wipe it with a special napkin.

Software

Unlike many manufacturers that produce their own shells as a software addition to the software, Lenovo decided to go its own way. Thus, the Lenovo S660 smartphone was initially installed with Android version 4.2, which was later updated to Android 4.4 KitKat. The proprietary shell – LenovoUI – is a kind of launcher with useful additions.

Will be useful

Basically, the functionality of the device is limited to the capabilities of the “dry” version of the operating system from Google, since the shell itself can perform only a third of all the functions of the system. This solution is very controversial, but it has its advantages - low power consumption and low demands on the phone’s hardware.

Some of the programs are proprietary, that is, from Lenovo itself, the other part are universal from third-party developers

Installed applications available out of the box are the same social network clients and branded ones from Google - from the browser and Gmail to Google+ and Google Play.

Sound

The main speaker of the Lenovo S660, as experience has shown, does not fully cope with its task. Its main drawback is the low maximum volume level, which prevents you from hearing an incoming call in noisy places.

The sound quality also leaves much to be desired - when listening to soundtracks at maximum volume without a headset, wheezing and tapping can be heard, which seriously spoils the overall impression of the smartphone's audio capabilities.

Lenovo S660 is capable of providing high-quality music listening

The top, bottom and side edges of the smartphone are reserved for the main controls and connectors. The lock key and volume rocker are located on the right side, the headphone jack is on the top, and the Micro-USB port is on the left side of the bottom.

When you connect good headphones, the situation improves. The ratio of low and high frequencies is at a relatively normal level; in extreme cases, you can use the equalizer to adjust; The vocals are not very pronounced, but the overall picture is quite good.

Compared to other devices running on similar chipsets, the Lenovo S660 performed quite well.

The “engine” of the Lenovo S660 is the quad-core MediaTek MT6582. Working in tandem with the Mali-400 graphics accelerator, the processor shows good results in terms of performance compared to other budget devices of that generation.

Today, of course, these indicators will seem small, but the smartphone copes with the main tasks flawlessly. Games of the GTA:SA level don’t even need to be installed, but with less resource-intensive ones things are much better - the same Temple Run or Skater Boy will run without problems.

Lenovo S660 will cope flawlessly with the basic tasks of a smartphone

It is important to know

Considering the low frequencies at which the processor cores operate, the phone's heat generation and battery consumption are moderate.
