I had something weird happen today.....I charged my battery yesterday and this morning was at 80%. Went to work checked email, still at 80%. Talked to my wife for about 5 min. then it said 5%. I was thinking how the hell can I lose 75% in a matter of a few minutes. I charged to 100% and now it's 7 hrs later and at 80%. Very weird I hope I dont see it do that again!
