I am beginning to suspect a design error in specific hardware models. There are too many people with battery drain issues to ignore. At the same time many people seem to have no problem.
Have you tried to revert back to an older firmware version? That could make a difference... I will try it when I find some spare time.
No I haven't tried an older firmware version. Wouldn't that require flashing the phone? Although, my phone has been back to Nokia roughly 3-4 times now, and each time it comes back with a different firmware. I've had the system board replaced, lcd assembly replaced, battery replaced and something else I believe.
You'd think after all these repairs I'd have a phone that actually works correctly...
