I noticed that the mini at times has quite poor battery life. for me, the main offender, according to battery usage in settings, was "Phone Idle". I do not know exactly what is causing this, so if any of you know, let me know Anyways, i noticed that in wifi-settings, if u press the option key, and tapp advanced, the Wifi was set to be enabled even when the screen was off. This can be changed to improve battery life. What helped the most on my battery life was an app called Juice Defender. There you can set that APN and Wifi should be disabled during the night, when the screen is off, and many other conditions. For me, theese things together, made my battery life go from half a day to 2-3 days battery life. Anyone have good battery life without this? Anyone with sync enabled?
