I have an iPhone 3GS and recently did a clean restore to 3.1.3 and jail broke with Spirit. After that I restored my back up settings to get my contacts and etc back and the battery life is ridiculous now and I never had this bad battery life when I was on 3.1.2 with Blackra1n. I really dont know why its this bad. I left at 5 pm with 94% battery and by 2-3 hours I was on 40-45% without using it at all, maybe unlocked it a few times to play gpsPhone for a few minutes, but thats about it. Any ideas to whats wrong?
