Serious battery issue.

[Cometolon]

Hi folks,

got my Xperia U 3 days ago, out of the box I used it till the battery was dead and charged it fully and did that process again.

Now yesterday I had 50% charge and it went from that to 0 in no time and turned of. Today it happened again.

Can someone help me please?

Thanks in advance.

charge your phone 100% -> press and hold volume up and power -> use it as you normally would, do NOT charge it at all

once you get to 10%

settings -> about phone -> battery use

take screenshots of the battery graph and the list of apps and services

tap on each item on the list and take screenshots or write down everything and post it here

remember that the more you sync the faster your battery will drain, also if you are using taskillers, battery apps or antivirus they will create a lot of issues and drain your battery faster

Come to think of it, the battery indicator doesn't come to 10%, it goes from about 50% to switching off...

there's something wrong, repair it with SUS or PCC
