i know this has been posted before. but i ordered mine and have not used it yet. but i read all abiout the bump charging so i decidied to try it on my stock battery well guess what....... my stock battery which is usually 90% full after doing a 10 minutes of use and practically dying every night after 13 hrs. well i charged my stock battery, unplugged it powered off and on and bump charged it for another hour. and after 10 hrs i have 80% left. i checked facebook, texted, a few calls, pandora for 30 mins streamed to my car with bluetooth, and bluetooth on the whole time and GPS on for 5 hrs but not using the maps app. is this battery life possible from the stock battery? i ordered the seidio 1750 and its in the mail but i may just send it back if this is what i'm getting off the stock battery.
