I have a major problem. My iPhone has been loosing battery life for a solid 2 years since I bought it but now it started shutting off at around 20% then today it was 30%. Some times it just shuts off while I'm using it and other times I'll just look and it will be dead. Then when I power it on it shuts off again before it boots up then it says to plug it in and won't turn on till I plug it in. When it turns on it says a little less percent than what it said when it just turned off. It happens all the time. I can't reset the battery gauge cause I can't get it to zero. I have a 3GS running 4.3.3. It is jailbroken. Any info on how to fix this or atleast fix until november when My contract is up and can just get the new iPhone?
Thanks
