Apple’s iPhone 3G users are going crazy on the significant drop in battery life. Everyone has observed this after upgrading to the new iPhone 3.1 OS. Before upgrading to OS 3.1, iPhone could be used normally without charging for about 3 days, but now it’s gonna be an every day routine. It would be a nightmare if you are using many applications as you would be forced to recharge it continuously.

What’s going on with iPhone? Defective battery? Defective battery meter? Nobody knows yet as Apple is still investigating all the surge of complaints.

Some quick solutions tried to extend battery life:

• Disable GPS location services
• Use Edge Wifi when available
• Don’t use bluetooth

But the above solution did not help either as battery life dies in less than a 10 hour in a day. This occurs even when there’s no change in usage, push mail, WIFI, brightness and other settings. Battery even drains in sleep or suspend mode and it seems to be warmer than usual. Worst of all is that the battery life drops even faster during phone calls.

Those are some common observation by iPhone 3G users after upgrade to 0S 3.1. Thus, if you have an iPhone, it’s better to wait and see before doing an upgrade to the latest 3.1 OS. You can read more about poor battery performance after iPhone OS 3.1 upgrade and spare yourself from all the trouble.
