iPhone ios 6 Charge Issue

I noticed an issue this morning when I took my phone off charge that it only charged to 99%. The phone has never done this before and was on charge all night. My best assumption is that it is related to the update. Has anyone else noticed this?

So, here’s how things work: Apple does in fact display the iPad (and iPhone and iPod Touch) as 100 percent charged just before a device reaches a completely charged state. At that point, it will continue charging to 100 percent, then discharge a bit and charge back up to 100 percent, repeating that process until the device is unplugged.

Doing so allows devices to maintain an optimum charge, Apple VP Michael Tchao told AllThingsD today.

“That circuitry is designed so you can keep your device plugged in as long as you would like,” Tchao said. “It’s a great feature that’s always been in iOS.”

That story states that during this process that the device will display a 100% charge the whole time (so that it doesn't confuse the consumer) which my phone always has displayed 100%. This morning, however, after being on charge the whole night it didn't register that it was fully charging. 1% isn't a huge deal but it is something odd that has occurred after the upgrade. My biggest concern is that 1% may turn into more than that later.
