Help in choosing a phone for the army.?

Question

Mobile devices

Good days. Now I am serving and I need the help of people who understand smartphones. You need a budget phone with good autonomy, as well as the presence of 4g and preferably fast charging. Something like zte blade a6, only cheaper. Thousand for 8.
There is no way to surf the Internet in search of.
Very often we are in the fields where there is nothing to do, and in order to kill time, it is necessary that the hardware does not suffer much against the background of the battery.

Answer 1

Look at the money that you are willing to spend on the device.
I would also buy an external battery (powerbank).

Answer 2

And what, smartphones in the army are not already nailed to the "Honor Board"?

Answer 3

There was a series of Philips Xenium smartphones and phones with a long lifespan. For example, W6610 can live on a charge for weeks. But the phone is morally obsolete for a long time. If you look at more modern models, then you can look towards Xiaomi Redmi 3X or 4X, where X means a reinforced battery.
