Hi,

I used to have battery issue after upgrading my 3G from fw 2.2.1 to Fw 3.0. Battery would be down to 30% by lunch time. My settings then was PUSH mail ON, Location Services ON, Bluetooth ON, IM+ after exit stays online with push notification on for another hour. It was rather frustrating and I find that I have to charge it up before I leave the office.

Now with these changes made

1. PUSH mail OFF, I now configure fetch mail every 15 minutes
2. Location Services OFF
3. Bluetooth - ON
4. IM+ goes offline after exit with home button.
5. Push notification OFF
6. Brightness 40%
7. 3G on all the time
8. Wifi OFF
9. ALMOST LEFT THIS OUT. I disable MMS and this seems to make a lot of different.


I find that with these changes made, with moderate usage I still have 30 - 40% of battery at night and I charge my iPhone every night with the charger on my bed side table as it is my alarm clock. So everyday I have a fresh 100% battery when I leave the house . And I just purchase a FastMac Truepower IV as a backup charger that I keep in my bag, this Truepower iV has 3100maH and a nice flash

This is how I solve my Battery issue on my 3G FW 3.0
