my xperia ion battery issues

[khimmy]

Hello, my xperia ion turns off everytime i launch an application. when I try to reopen it, after a few seconds, it will turn off again. Is it the system or battery? I can't used it well and as what I noticed, xperia ion's software and battery really has a problem . I hope SONY can resolve this problem ....

Check if booting the phone into safe mode may help and run any pre-installed application. If it works its most likely a problem with any of the third party app's you have installed.

Does you Xperia power off by itself with EVERY app you open (even browser and stock apps)?
