Hi there, lately I have noticed my iPhone 4S (on 5.0.1) battery has been dying a lot quicker. I can barely get out 2~ hours of usage and 8~ hours standby. I am jailbroken and here are my packages: Activator biteSMS BytaFont CyDelete FolderEnhancer gpSPhone iFile OmniStat for NotificationCenter OpenSSH PasswordPilot ProTube Pull To Refresh Safari SBSettings Springtomize 2 WeeFlashlight for NotificationCenter WeeKillBackground for NotificationCenter WiFiFoFum Winterboard I have 4 email accounts set up on my phone, 3 are set to fetch every 15 mins. and one is set at push. I have iCloud setup for Daily Backup and to sync Reminders, Calendars, Mail, etc. I have tried to remove all my Mail accounts and re-add them but there was no difference. I have iMessage activated. In terms of Push Notifications, I have one app that sends me them frequently: ScoreMobile, it sends alerts of sports teams I follow when something important happens. Previously I was able to have ScoreMobile push on 24/7 and my battery would be perfectly fine. In terms of charging, I usually let the phone die before I charge it and I charge it to 100%, sometimes I charge it overnight for around 8 hours. Does anyone have any tips for me?
