Hello everyone, first post on this forum!

I have an Xperia T3 model, I love it, but I have questions about the battery longevity.

If I do a factory data reset, the battery last for weeks, sometimes more than three weeks if I don’t get too many calls, but as soon as I charge it, it won’t last more than a day!

I followed the manual, I’ve updated the software and waited a week, same problem, the battery goes down really fast, but as soon as I do a reset, the battery last for weeks.

I tried to turn everything off, data, Wi-Fi, I’ve uninstalled apps I don’t need, nothing works!

Any help or suggestion would be greatly appreciated.
