    Guys

    Can anyone help with this please? I got an S2 a few months ago from T-mobile and it was running on gingerbread, battery life was good, would last two days on standby if i didnt use it much. Then suddenly one day it started draining battery really quickly. I went away on holiday and took my phone with me and didnt have a charger so it turned itself off with zero battery for a few days. Came home, charged it up and it was still draining battery like nobodys business. I thought i'd try ande get to the bottom of it and i was removing apps, checking for viruses, turning data connections off etc. I even resorted to factory resetting the phone, it didnt work though.

    Eventually I upgraded the OS to ICS 4 via samsung kies as part of the ICS rollout, but battery was still being drained and I wasnt getting the 2 days I used to get on standby. I downloaded better battery stats to better understand the root cause of the battery drain. Below is the results, the phone is in deep sleep most of the time but still drains so much battery. have a look at the below stats, 35% battery drain in 6hrs 37 mins. is that normal? According to these stats battery would only last a total of 1134 mins or 18 hours. far from the 2 days i was previously getting.

    Any ideas why it is doing this?

    Try removing your battery for at least 30 seconds. That helped me when I was having batttery issues.

    If you still continue to have issues, you can always go back to Gingerbread using Atmazzz's guide. http://androidforums.com/samsung-ga...ide-how-revert-gingerbread-ics-go-ics-gb.html

    Then either stay on Gingerbread or trying upgrading again to ICS but use Odin instead of Samsung's kies software. I've heard that helps some people with battery issues.

    Edit: Actually it looks like you have the international version of the Galaxy S2, in which case, the guide I linked will not work. Try looking on this forum for a solution http://androidforums.com/samsung-galaxy-s2-international/
