OS v2.2 Battery indicator always shows full until device dies.

After I upgraded to version 2.2 of the OS on my iPhone 3G, my battery indicator is always showing 100% charge. After a full day of normal usage, the iPhone just died with a dead battery. I didn't even get the usual warning when the battery was at 20%.

Has anyone else experienced this problem?

MacBook Pro, Mac OS X (10.5.5), iPhone 3G OS

That problem has been around for a while. If you now give it a full charge, you will (most likely) have solved the problem. It sort of fixes itself most of the time simply by running the phone down all the way, then recharging all the way.

It calibrates the charge measuring circuit.

Post back if it persists.
