Hey all. First, here's how I like my phone set up: I never use 3g at home as I'm in a very weak signal area and know it kills my battery constantly hunting for a signal. I rarely use 3g anywhere else either - I don't use push email, instant messaging, twitter, facebook or anything else like it. If I need 3g I'll switch it on. I also don't like my phone 'doing things' I haven't told it to. Now, I fully charged my phone last night. I took it off charge at 00:30hrs and didn't touch it at all until 12:20pm today, yet the battery has dropped to 75%. I checked and it shows Android OS at 94% (with CPU usage of 5h22m46s), cell standby at 3% and phone idle at 2%. I already use Juice Defender Ultimate, and I've installed Better Battery Stats which doesn't show anything in particular that equates to that amount of CPU usage. So, how do I find out what it is that's causing it? Or, do I not worry about it as that's normal for this phone? I don't see how it could be, my iPhone 4 would lose at most 2% battery life if left the same way. Help!
