My 3GS battery isn't holding well. Not sure if it is a program draining it or if the battery is just too old. I've had it since the 3GS came out. Could this battery just be past it's lifespan? Maybe I'll toss a replacement in since they aren't too expensive.

It's been 2 1/2 years since the 3GS came out, of course the battery isn't going to perform as normally. Replace the battery and everything will be good.

I went from 4.3.X to 5.0.1 to 4.3.5 last week. I didn't like 5.0.1... Too many things I like didn't work right. So I went back. Battery life before 5.0.1 wasn't great, but now it's horrible. Went to bed at 91% woke up at 85%... was in sleep mode the entire time. With minimal usage today it's at 35% now.

Any notorious jailbreak apps that really kill battery life?
