My Nokia Lumia 800 has a question mark on its battery.
I have upgraded to the latest version 1600.2483.8106.11500
And this did not fix the problem.
On the battery status screen via the diagnostics screen . all the values are just 0.
The upgraded has not fixed my battery problem.
NOKIA please help.... what should we do
It seems the only solution is to bring your Lumia into a Nokia Care Point for a substitution.
I hope Nokia speeds up the shipments of this new Lumias, because they didn't offer me a substitution phone
