CATerpillar S31 16 GB / 2 GB

A smartphone from the world-famous manufacturer of "adult" special equipment CATerpillar is able to survive falls from a height of 1.8 metres, is not afraid of vibrations, diving under water and operates in a wide temperature range (from -30°С to +55°С).

Always ready

If we start talking about specific designations of CATerpillar S31 security, then the device is assigned an IP68 protection class, and it is also made in accordance with the requirements of the American military standard MIL-STD-810G. The tenacious grip of the smartphone in the hand is facilitated by rubberized body elements with protruding transverse stripes. And mechanical controls help to cope with a mobile gadget with dirty hands or gloves, including subscreen navigation keys. A separate customizable yellow button is placed on the right side of the device — by default, the flashlight function is assigned to it.

Responsiveness

Performance is not the strongest side of the “armored car”: the simplest Snapdragon 210 chip in conjunction with 2 GB of RAM handles well with undemanding everyday tasks, but is completely unsuitable for turning “heavy” applications and running resource-intensive games. For those who need a faster secure device, the manufacturer's lineup includes a CATerpillar S41 smartphone running on a MediaTek Helio P20 chip in tandem with 3 GB of RAM. Both modifications of "SUVs" are running Android 7.0.

Long battery life

The cameras that the smartphone has at its disposal are represented by an 8 MP main photo module and a 2 MP front camera. They do not grab stars from the sky, and the overall result of their work can be described as very mediocre. CATerpillar S31 deserves praise for supporting 3G and 4G networks, as well as for long battery life — taking into account the non-gaming platform, the energy reserves in the 4000 mAh battery are enough for 2-3 full days of gadget operation. The overpriced price tag slightly spoils the overall positive impression of the smartphone, but the ability to work where others cannot completely eliminates this drawback.
