Tmo S3 on ATT - battery drain?

[vince2398]

I am using a TMO S3 unlocked on ATT using the HSPA+ APN but seems like the battery is draining fast, is anyone else also doing this where they can provide a fix or know why the battery is acting like this? Thanks in advance.

Check battery use. May be it has battery problem :-S

Could be many things.. Poor coverage, rogue app, bad flash, bad download.. We would need more information in order to help narrow it down. Download GSam battery monitor to find out what is draining your battery first, then post screenshots of the list along with battery settings, such as screen time, etc.

Thanks for the tips. However, things are normal when I am on wifi and not connected to mobile network. Also, this doesn't happen on an ATT phone in the same area. So I was suspecting it's APN settings?
