Hello everyone, first time poster here, long time lurker. I decided to post here in order to be able to have some help with my Samsung Galaxy S2. I have had the phone for a little over a year now in Canada. I am not exactly sure what the difference between the international version and my version are, but the model on my phone is the GT-19100M. There are just so many different models of the S2 that it becomes a little confusing. So i am currently running the official version of ICS, i have inquired about rooting it for a while now however there are so many version that I just cannot rack my mind over it. I'll start off with the problems. Ever since I updated to ICS a while ago the phone began lagging much more. Now the really serious problem is the battery life. I find that the battery lasts about 4 hours if I am lucky. For my usage here, all I use it for is texting, the occasional call, and a little of facebook/instagram (but try to keep it very little). I find that I cannot use the phone too much because it will overheat and then the battery will drain very fast. I looked around and found an app called juicedefender and installed it and it helped the battery life for a few days but it went back to the same. I find that if I do not carry around my charger and hoping to find an outlet that my phone becomes nothing more than a paperweight. I am currently running stock ICS 4.0.3. And I have the backlight on the screen to the lowest possible, the wifi turned off when i leave home so it does not search for anything, the screen lock timed to the lowest (15seconds). I feel that this phone is just annoying me so much right now that i want to go back to a flip phone that lasted me like 3 days without charging. I understand that its a completely different ball park. If there are any options or help with this I would gladly appreciate it, any input whatsoever because I am very annoyed with this phone that used to be very good when i first got it. Thank you everyone for your time.
