Help Battery question and something else

[kissofthehell]

First of all im using Xperia Play if that matters. Yesterday around 2 am i left my phone on table near my bed with alarm turned on. 5-6 hours later i find my phone off and battery at 0% when i left it it was 85-90% not sure. I asked my friend with xperia phone too (not play) and he said he had that thing once too. I think this is 2nd time happening to me. Its not like every day.. more like every 1-2 weeks or something like that.

Another question: How to root my phone and can i brick it like failing hacking psp ?

Hello and welcome to Android Forums.

It could be that the alarm kept going off and nobody was there to turn it off so the battery ran out. Yes, if you don't root your phone correctly then you will brick it and rooting it will also void the warranty. Always do your homework and research rooting before attempting it. Each phone has it's own way of rooting it and any other root method for another device will not work with yours. Please think about it and do your homework before rooting your phone I would hate for you to brick it.

Its impossible to be the alarm because it was set for 7am and i woke up around 7:30.. even on my other crappy phone 90% battery would run that fast out just from ringing 30 minutes

If the alarm is left running for an extended period of time this will drain the battery fairly fast as the display is also lit up for this period of time in most cases.
