I did a yet last night to see what helps. I love this phone and always on. Usually got any where from 6-8 hours on one charge. So after reading a few posts and watching a few videos I tried some bat saving tips. Just 2 really. I got rid of my bat percentage widget and I manually put the brightness down to 20%. I started the test with 90% and am now at 40% and its been on for 15 hours with 3.5 hours awake.
Edit: not in 4g area
