Nokia Lumia 800: delightful smartphone but with a few irritations. If you have one, I recommend that you do not let the battery fully discharge – a challenge since the battery life is not the greatest – since if you do, you may have problems turning the phone on again.
I am not sure what proportion of Lumias are affected, but what happens is this. The battery runs out and the phone turns itself off as you would expect. You plug it into the charger, but even after several hours it appears to remain uncharged and will not turn on. The problem is discussed in this thread: Lumia 800 won’t power on or charge.
This has happened with my review Lumia. In my case, the phone vibrated when plugged into the charger and the charging screen appeared, with a red line showing an empty battery, and there it stayed.
So what is the fix? I have had the problem a couple of times, and each time it eventually fixed itself, though it is hard to pinpoint the exact fix. Things people have tried:
- Unplugging and reconnecting the charger to the phone
- Attaching the phone to a PC, then to a charger
- Reset the charging cycle by holding down the power button, while charging, for 8 seconds or so
- Warming the device to create a small charge in the battery, then starting to charge it
One theory is the battery discharges so deeply that there is not enough power to detect the charger, therefore it never charges. Kind-of too smart for its own good.
If the phone had a removable battery, I would suggest removing and replacing it, an old trick to revive a frozen phone. Should your Lumia not be covered by a warranty, you could try disassembly in order to do this.
The best hope is that a further firmware update will fix the problem.
