Liquid E700 Battery Problem

Antonl

Hi everyone,

I am posting this message because I have a problem with the battery of my Liquid E700.
I had buyed my phone in France in september 2014 and today for charging my phone from 15% to 100% it takes less than a hour (with the original charger --> 5V, 2A) and the battery during not very long as at the beginning.

Can somebody tell me how can I saw if it is a problem of calibration or it is the end of the life of my battery (and of my phone, because it's not removable ).
I have realised the test of the battery with "AnTuTu Tester" with Wi-Fi activated and the brightness at 100% and I obatained the score of 4859 points (either 2h50min with screen-on).

I wait for your replies because I need your help, and sorry for my bad English.

you can't do much to calibrate battery, apart:

1) power off your device and charge it until it's at 100%; then power on

2) do a factory reset (you will need to backup all your personal data) - settings/backup & reset - Factory data reset
