I was having a serious battery drain issue and restored Iphone w/o jailbreaking. Had many apps and din't want to start taking out one by one so I started from scratch. For a week I used the phone stock and the battery performance was excellent but I missed the functionality of what I had previously. All I have installed now is the following, App List, Ask to Call, Big Boss Icon, Bug Fix Duplicate Icons, Bug Fix, Stuck Pages, Cydia Installer, Cydia Translations, DePersisit Wifi, Infinifolders, Mobile Substrate and Substrate Safe Mode Some of these seem to have been downloaded with the Cydia install. Would any of these cause battery drain?
