I noticed this a few days ago and thought it was a one time thing... well, it wasn't. Whenever I get the low battery indicator on my 3GS, the percentage is WAY off. As in... it just told me I had 93878896% left. It definitely should have said 20%. I haven't compared them to see if they all have the same crazy percentage listed, but I was wondering if anyone else had this issue. Any ideas on what it is? BTW, I'm jailbroken via purplera1n.
