This week I saw a man talking to his iPhone. Not into it, to it. “No, no, just a little longer,” he pleaded. But from his frustrated sigh, I’m assuming the phone died anyway.

Turn off the “push” option and increase the interval between when the phone checks for new messages. Your best bet for increasing your battery life is to check for messages manually.

Turn Off Everything

Disable Animations
The hotter your laptop feels, the more battery power it is using. One of the biggest power hogs is Flash animation (used to run online videos and animated ads). Disable Flash when not using wall power, and consider using a program that automatically restricts Flash (BashFlash and ClicktoFlash for Macs and Flashblock for PC).
