Lenovo S750 - a smartphone with IP67 protection class

Lenovo S750 - Lenovo's new smartphone with IP67 protection class.
IP67 protection class is as follows:

• Dust cannot get into the device. Full contact protection
• Short dive to a depth of 1m. Permanent work in immersed mode is not expected.

Today, we will test the phone not only with synthetic tests, but also check the water resistance of the phone in practice.

The first in the line of IP67 smartphones from Lenovo was the A660 model. Lenovo A660 and Lenovo S750 unites only IP67 protection class, the other characteristics have become much more interesting.
The S750 has become larger - 4.5 inches, the screen is made using IPS technology and has a resolution of 960x540 pixels. The platform has also changed - now it is a 4-core Mediatek 6589 chip, the amount of RAM has increased to 1Gb.

► Appearance and equipment

The smartphone comes in a proprietary Lenovo box:

')
Apart from the phone, only the charger and the USB cable are included:


The phone looks bright because of the orange insert on the side.


Which indicates that the phone is not afraid of water:


Bright orange color is not only for the sake of beauty, but also has a practical meaning - the phone is easy to find in the grass or in the snow.
The size of the phone is noticeably larger than the 4-inch A660


The back panel is made of corrugated plastic:

The screws on the perimeter are only decorative.

The smartphone lies in a hand conveniently:


The truth is a little lacking emphasis on the side faces, as it was in the Lenovo A660, for a more confident grip.

(top - Lenovo A660, bottom - Lenovo S750)

In front are 3 touch buttons with backlighting: “Menu”, “Home” and “Back”.


Headphone input and microUSB port are on top and hidden under a protective cover:


The volume buttons are on the left:


The speaker is on the bottom left:

A small protrusion does not allow to completely close the speaker by putting the phone on the table. The sound is loud, without wheezing at maximum volume.

Rear 8MP camera with flash:


Remove the back panel:


2 SIM card slots for work in GSM and WCDMA networks and MicroSD memory card slot:

The work of SIM cards is organized in the "waiting" mode, when calls can receive both cards, but if you talk one by one, then the second one will not be active.

2000mAh battery:

► Screen

The Lenovo S750 is equipped with a 4.5 inch IPS screen with a resolution of 960x540 pixels. It is covered with protective glass GorillaGlass 2.
The color rendition of the screen is good, but the maximum brightness on a sunny day seems insufficient.



The viewing angles are good, with a slight tint of blue with a strong horizontal deflection.

► Software and performance

The Lenovo S750 is pre-installed Android 4.2.1. At the moment there is no fully Russified firmware, there are only assemblies with partial Russification.


The smartphone is built on a Mediatek 6589 chip, which consists of a 4-core Cortex-A7 processor with a frequency of up to 1.2GHz and a PowerVR SGX544 GPU.
The RAM is 1 GB, constant - 4 GB.
The results in synthetic tests are very similar to the results of other models on the MT6589.
Antutu Benchmark 3.4 - about 14000 points, Quadrant - 3976 points


Vellamo with a stable high result in the HTML 5 processing test:


The test of the graphics subsystem Nenamark2 dials 48.8 fps:


The performance of the chip is enough for arcade games:


And 3D:

► GPS and Wifi

GPS cold start took about 2 minutes, active satellites 6 and the signal level is good:

I am glad that many of the latest models of the MT6589 have a built-in compass that will help you navigate the direction on the map.

Wifi accepts well, both near the router, and through the obstacle in the form of 2 walls:

► Camera

The resolution of the rear camera is 8Mp. And the pictures are pleasantly surprised: normal color and white balance in automatic mode.

► work time

The battery capacity is 2000 mAh. Let's look at the results of the synthetic test Antutu Tester:

680 points - a very mediocre result.

In practice, the battery consumption graph is as follows:


In details:

(in the program for some unknown reason about 40 first minutes of the on screen were lost)
The activity on the graph above is approximately the following: 4 hours of games, 2 hours of active surfing on Wifi, the rest of the time Wifi is simply turned on.
Perhaps the problem of such a fast battery consumption lies in poorly optimized firmware.

► IP67

Protection against ingress of water into the inside provides a rubber gasket located around the battery and slots for SIM cards.

Also protection serves excellent build quality, without gaps and gaps.
We turn to the most interesting: water resistance test.
Normal dive and call taking:

Underwater video shooting:


When immersed in fresh water, you may accidentally press the screen. Also under water touch screen does not respond to pressing. Accordingly, if you want to remove something under water, then the camera must be turned on in advance.
The phone successfully survived a dozen doubles. It was scary only for the first time, and then it even started to like it.

► Pros and cons

2 sim cards
Safety glass Gorilla Glass 2 on the screen
IP67 protection against dust and water
Excellent build quality
Good rear 8MP camera
Short battery life

Lenovo got a very worthy continuation of the line of phones with protection class IP67. Safety glass Gorilla Glass 2, excellent build quality and a modern hardware platform for 2 SIM cards will definitely come in handy for people leading an active lifestyle.

► Price

The price of Lenovo S750 in China is $ 210-215 including free shipping to any country in the world.
