I finally got Cyanogenmod 7 on my phone yesterday, and one of the main reasons I spent all day fighting with my phone was to improve my phone's battery life. This morning the phone was all charged up, I took it off the charger for a couple hours. I send a few texts and run to the grocery store, as I'm walking in, I get the 15% battery warning. What the hell! I thought this thing was charged! Then I get back from the store 15 minutes later, take the screen shot below, and plug it in. Suddenly it says that the phone is a 60%? I have no clue what is going on with my phone or why. Also, I need to know some ways to save my battery life. I set my Facebook to only update once an hour, email every 30 minutes (maybe an hour, I forget), set the automatic brightness. I need my phone and I bought a car charger for it, but I shouldn't have to worry every time I leave the apartment that my phone's going to just randomly die on me. So what do you guys think? Any suggestions on how to fix this?
