I have looking at this battery thing a little bit seeing if I can eke some more out.
Downloaded the infamous GSAM.
I charged yesterday and left overnight without really using it.
A few text, emails etc.
I did the tip of charging fully and then unlock the screen before removing the cable as there was a suggestion this may cause an issue with wakelock.
I left data, email, notifications on.
I only reduced the volume to vibrate.
I had 2 gmails at 3:38 in the morning and my phone was flashing at 6:50.
I took a few screenshots.
These last one was interesting as it appears to me to show that WITHOUT a good signal, it doesnt use much battery?
