I'll preface this post by saying I'm a very heavy mobile user as I have 3 push email accounts, get a ton of text/whatsapp messages and use my phone for reading RSS feeds and browsing the web throughout each day. That being said, I'm quite surprised at how poor the battery life is on my new Galaxy S2. I've tried calibrating the battery by running it all the way down and charging it to 100% twice but I'm still having the same results. I'm coming from an iPhone 4 which had a pretty good battery life and got me through most days but if I'm not near a charger, my GS2 will be dead by around 3pm. Is there anything I can do to increase battery life (without making my screen brightness close to nothing)? Any other tips I should know about? Thanks.
