First off...let may say I was not getting on any first time posters...we are all there at one time. Just the part about not wanting any people not having the issue to post threw me. This being said...I dont keep my brightness at max, but near max. My screen is still always my #1 battery eater and then throw in some Wifi, Phone idle (usually up there as well) and the android os. Right now my display says it is the cause of 42% of my battery usage. This being said...no doubt I am getting an increase of at least 20% and probably more. I will say that I made a post a week or so ago because my battery was draining extremely fast. I deleted a bunch of apps and did a battery pull and have never had the issue again. Hind site would say I should have done the battery pull first and check but oh well. I still believe it was one of the 15 apps I deleted that was doing the damage.
