iPhone Tip: Push & Battery Life

If you're using Google Sync to push changes to your Calendar and Contacts back and forth from your iPhone to the cloud, you may have noticed your battery life is drastically reduced. I estimate I get about half the usual standby time when I'm roaming around with push switched on. It's not so bad when I'm at home and have a WiFi connection.

This may seem obvious, but if you switch off 'Push' in Settings > Fetch New Data or change Settings > Fetch New Data > Advanced > Your Profile Name to 'Manual', it will still sync, but only when you open Contacts or Calendar.

It's almost like having a fresh new battery!

BONUS: A nice side effect is that GSM buzz is reduced because the phone isn't in constant communication with the big G's servers.
