HTC One X - Horrible Battery Life

view story

http://forum.xda-developers.com – Hi All, Recently switched from an iPhone to HTC One X and I am quite disappointed so far. Does anyone also endure poor battery life with your HTC One X? I am not running much applications in the background either, if I charge my phone to 100%, I go to bed and wake up its 80% without me even touching the phone... and it hardly lasts me half a day without charging. Does anyone have any tips to improve battery life? Oh, and my screen brightness is always at 0-25%... thanks for any help! (HowTos)
