Something similar happened to me just now. HD7 with Mango on it.
The battery level indicator was low, so I connected it to my laptop. The battery indicator changed as if it was charging, but the battery charge level remained at 0% (I can see this in settings - battery saver). When i disconnected the phone, the "Clitically low battery" message appeared. I tried pluging-it into the power outlet, but the same thing was happening. It didnt seem to charge the battery.
Then I removed the battery for a few seconds, put it back in and turned on the phone. The battery level is now 51% and it's charging.
So even though WP7 didnt know, the battery was charging. But the OS kept saying that the battery is empty.
Should I worry?
