Testfreaks.com recently posted 10 ways that you can save the juice in your iPhone battery. Several of these tips may seem obvious, but you would be surprised by all of the iPhone users who have shortened-battery-life complaints without taking a few easy measures.
On to the tips:
1 Turn down screen brightness
2 Adjust for less frequent e-mail checks
3 Turn off WiFi
4 Enable auto-lock for the screen
5 Turn off the equalizer
6 Buy an external battery
7 Use a mobile battery charger
8 Disable vibration alerts
9 Disable Bluetooth
10 Update the phone frequently
As of yesterday I have instituted all 10 tips. I'll report back with my findings.
It can also be noted, that when one uses their iPhone more frequently the phones battery becomes calibrated to the individuals usage pattern, in turn providing better battery life.
