Errattic Battery Meter

[patvet10]

Hello all, just jailbroke today with Spirit on my 3GS 3.13. My battery will show an amount like 89 then jump up to 98. What is going on here? If I shut it off it will go back down then jump right back up.

I have exact same problem aswel

Well I did a restore, still having this battery problem. I never had it before I installed the spirit jailbreak. So I don't know what is going on. I can't believe that no-one else has this problem. Should I do a restore and take it back to apple?

I had the same issue on 3.1.2 i revirginized my iPhone and all was well again. I did the spirit hack when it came out on 3.1.3, and I'm experiencing the same erratic battery life, also to not I have noticed a significant drain in all around battery life with just winterboard installed.

does it only happen with 3gs 3.1.3?

Well I am on 3.13 so I have no idea what is going on here. I let the battery drain all the way to dead, and I am recharging now. I will keep you guys posted. It still seems like I am having the erratic battery readings.

i have had this on 3.1.2 and seen a few reports similar.
Lasted about a day and then was totally fine, which was basically the only 'fix' i could find online.
My advice is just to leave it for a while before committing to a full restore, and the hassle that can bring.

I do not believe this is related to jailbreaks.

My 3.1.3/3GS does this quite frequently. It's usually minor, like after a full charge I'll unplug and it'll quickly drop to 99 or 98% - then if I restart my phone it says 100%.

Then I've also had the jump ups like you describe. Almost like the battery took a quick reading, then went back for more details.

Other times my phone would get warm and start draining battery quickly - I'd restart and it would show like 3% then jump to 22% or the like.

Could be a faulty battery sensor, or something with how the 3GS works, or even a software bug.
