weka Posted November 26, 2014 Share Posted November 26, 2014 Looking to upgrade the battery on my Samsung S3 from 2100mAh to the 3500 mAh which requires a new, larger back cover. Has anyone had any problems doing this? I imagine you can get leather phone "wallets"/cases to accomodate the new enlarged back? Would be interested to hear if this battery upgrade a good thing to do, and if people have had success with such an upgrade thanks Link to comment Share on other sites More sharing options...
NamKAheng Posted November 26, 2014 Share Posted November 26, 2014 I know that Seidio is selling the 3500 mAh battery with extended back cover. Link to comment Share on other sites More sharing options...
weka Posted November 26, 2014 Author Share Posted November 26, 2014 I know that Seidio is selling the 3500 mAh battery with extended back cover. Yeah I've heard of them too, seem good. I spotted this website that looks convenient: http://www.promobilez.co.th/accessories/battery/samsung-galaxy-batteries?p=2 Link to comment Share on other sites More sharing options...
scubascuba3 Posted November 26, 2014 Share Posted November 26, 2014 I stuck with the normal size s3 battery, I have 2 spares, I carry one with me. I also turn data off now when I'm not using the phone, this is the major reason for the battery draining quickly Link to comment Share on other sites More sharing options...
