Just curious if any one else has notice this bug/issue.. Today when i got home from work i was messing around on my 3GS looking online when i recieved the 20% battery remaining warning. I continued to browse the web and listen to music. A few minuntes later i put the phone to sleep and then woke it again. When it woke from sleep the battery had jumped back to 25%.. Has anyone ran into this before? I have had 2G iPhone for almost two years and never notice that before. Not an big deal or even a problem just curious
