I faced an unusual battery issue with my iPhone 3G yesterday. I recently installed iPhone 4.0 on it, unlocked and jailbroke it too.

iOS4.0 has a feature (iOS3.0 also had it) wherein we can see the % battery remaining.

Yesterday, when my iPhone started showing me 8% battery remaining, I plugged it to power to recharge it and as soon as I did that, this device started showing me 72%. I was surprised to see that. Just to check, I removed the recharger and now the battery % settled for 63.

I don’t know why it happened and if it is some bug with the OS.

I don’t find it a reliable way to know the % battery remaining.

Any other way to keep eye on it??
