The iPhone 4 battery is supposedly 20% better than the 3GS and I still canít go one full day without having to plug my iPhone in. I realized that Iím not the only one having this battery issue so I figured Iíd post a few tips to maximize the iPhone battery life.

1. Make sure you kill those apps that are running in the background for nothing

2. Turn off wifi if youíre not using it (Settings > Wi-Fi and set Wi-Fi to Off)

3. Turn off 3G if you donít need it (Settings > General > Network and set Enable 3G to Off)

4. Turn off Push Notifications (Settings > Notifications and set Notifications to Off)

5. Turn off Bluetooth (Settings > General > Bluetooth and set Bluetooth to Off)
6. Turn off Push Email (Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off)

7. Fetch new data manually (Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually)

8. Go through a full charge cycle each month (charge the battery to 100% and completely run it down)

9. Turn off vibrate

10. Auto-adjust Brightness (Settings > Brightness and set Auto-Brightness to On)

Optional: turn your iPhone 4 off (just kidding )
