MW700 battery problem

[pendorchelo]

Hello people,

I would like to know if someone can help me with this problem on my MW700.
Suddenly the alarm of low battery began to sound and the phone turned off (the battery was charged all night and was over 80% at that moment). then everytime i turn it on it resets. It begins with the Gsmart logo, then windows logo and when the today screen appears the low battery alarm sounds again and the phone turns off. i have made a hard reset but this failure persists. the only way to make it work is with the wall charger connected but the battery doesn't charge (it's always at 5%).
I thought it may be the battery.....well, i hear your suggestions.
Thanks!

Max
