The device doesn't boot without a charger and turn off when heavy use.
The device was functioning properly since it turned off suddenly, now it boots at HTC logo then turned off and doesn't boot completely until I plug it with the charger or any power source.
I noticed that if i enabled the power extreme save mode and unplug the charger it keeps running, until I disable the power save mode and launch a (heavy to CPU) app such as Facebook it turns off again..
So is this could a battery failure or a system issue?
Many thanks in advance.
