Lately my battery has been... frankly... shit. It doesn't last 3 hours, and it has odd behaviour. While I'm texting, actively using data, and having the screen on, the battery is normal life, while it's asleep in my pocket, it's worse than actively using 3G, GPS, Max Brightness, BLuetooth, and the speaker. I used to be able to be actively using it all day, then one day, I update to Kaosfroyo v38, and my battery went down the drain. Please help me fix this.
