Before froyo, I could go entire day using phone and data, about 15 hours and only use about 33% of battery. After froyo, first day at about 9 hours battery was down to 33% left. I thought I had installed a new app that was misbehaving. I did a factory wipe, and only installed pre-froyo apps. Next day went the whole day and battery was down only 15%. Thought it was fixed until today. Hardly used phone (only one call for about 2 min. and no data usage on my part) and battery was down to 5% left at end of day. ATK is showing less apps running now than before froyo, and I have to keep killing ATT hot spot, and Daily Briefing. I can kill them and they start back up right away. Also the Android task manager shows nothing under active apps, even when I start multiple apps. This is unacceptable. I left LG because of a P.O.S. windows phone I had that they would never update and bought this phone because all of my appliances I have are Samsung and they are wonderful. I love the form factor of the Captivate, but can't believe it took this long just to get an update that when released is already OUT OF DATE. Then to add insult to injury this OUT OF DATE update if FUBAR. At this rate, maybe Samsung will go the way of Palm. I can't stand Apple and their products but will give them credit on their update of the iPhone and the stability (left me get the taste of vomit out of my mouth). Samsung, FIX YOUR SOFTWARE.
