Just in case you didn’t know it yet the Nokia Lumia 800 battery situation is a real mess and the latest firmware update made things worse in some cases. As you probably already know I have two Lumia 800s and both of them received the much awaited update recently unfortunately one of them (branded TIM-IT) isn’t really working as it should now. As you can see in the picture above the OS is unable to get a correct reading of the current battery status and the same thing applies to the Nokia Diagnostics app (picture after the break). My second device (branded SFR-FR) updated without a hitch and seems to be working fine though.
Rolling back to the pre-update state fixed the issue so the problem is definitely caused by the 1600.2479.7740.11451 firmware on this particular handset (the 7440 OS update doesn’t cause the issue as it only happens after the new firmware is applied). Unfortunately for me after going back and forth between the newest version and the restore point the Zune software has magically decided to erase my backup so I’m now stuck with the latest software on the device and this annoying bug. It seems that I’m not the only one experiencing this issue though so I’m posting this hoping that Nokia will take notice and fix it a soon as possible. If you have the same problem please post in the comments below.
