Have you perform a clear update/repair? which means everything will be deleted?

Latest available software: 6.2.B.1.96

Release started: 2013-08-26

The last update was released almost 2 years ago, there won't be any further updates, your phone it's more than 3 years old, it'll be wise to reinstall the latest update, if that doesn't work then the issue could be a hardware issue, perhaps you need a new battery.

Thanks very much I wil reinstall the update

[victor5]

But sorry to bother you again how can I go about reinstalling the update?

It'll be wise for you to check the XDA forum as you could flash a Custom ROM
