Our droid phones just downloaded a huge update a few weeks ago. That is the only thing that has changed on my phone in the last month, and all of a sudden my battery started dying really quick (within a few hours). I thought maybe I needed a new battery, but that didn't solve the problem. I've been trying to figure out why it's dying so fast, and have determined it is because the ANDROID OS is using too much battery, it is only at around 2 or 4 % on everyone elses droid phone that I know, and mine has started running between 80 and 95%. I know this is the problem because just yesterday it all of a sudden went down to 2% and the phone lasted all day and all night without dying. Then today it spiked back up above 80% and died within 2 hours. I can not figure out why it's doing this, like I said I haven't changed anything except that new update to the phone. I've been trying everything I can find online thats suggested like killing everything that is running, using task killers, I uninstalled my email and tons of programs, so far nothing has helped. Has anyone else had this problem? I would like to try anything and everything before doing the factory reset, which I'm not convinced yet will solve the problem, it might but it will be a pain to set everything up again, I'd like to know what the problem is in the first place! grr..
