Recently swapped from Android to the Lumia 920 so i know little or nothing about the OS.

Issue: Phone battery dies over night, in the morning when i plug it into charge for 15-20 mins the phone does not turn on/ shows no battery indicator/ no signs of life.

So i have to resort to doing a softreset everymorning in order for the phone to turn on. Originally i thought this was a faulty handset. However it might simply be a battery saver gimmick wherby the phone has to be charged for a longer period of time before it can turn on  or show any sign of life, after being fully drained..

I would appreciate it if anyone could advise me as to if this is normal for Lumia 920's ? or do i need a replacement handset

As with any device with a lithium ion/polymer battery, it is not reccomended to fully drain the battery regularly. Best thing to do is to charge the phone the night before to avoid this happening.

Thanks for the response!

I've been doing some research & my issue sounds similar to this old Lumia 800 problem:

"We heard about a software update designed to knock the problem on the head way back in november and in December the Finnish phonesmith admitted there was a problem, caused by a software bug.

The issue appeared to be that some Lumia 800s weren't charging fully. We've also experienced a different battery-related problem on our test unit, where the phone refused to recharge or turn on after the battery died."

The last part is exactly the problem, I've had other phones with those batterys none of which has this issue. I would assume this is a software problem although i have not seen anyone else report the same problem yet, might just have a defective device.

I've always been wary of letting Li-ion batteries run completely flat because they are known to remain in that state. The lowest I'll let my battery get is around the 5% mark.

 Incidentally, I've had my 920 since the 5th of November and it's battery has stabilised at around two days of usage after a full charge. I have it timed to roughly needing a charge at approximately 8pm every other evening.

Olny time I accidentally let the battery run flat on the Lumia920, I left it charge till it was full. Plus they phone will restart itself once the charge reaches a certain level. Try leaving it charge longer next time and see.

Incidentally I have this issue with my HTC Sensation Android. It's to do with the battery voltage dropping below a critical level below which the battery will refuse charge. Once this happens the battery can only be charged with special chargers or can usually be coaxed into recharging by using a high powered charger with regular disconnects and reconnects. The phones software is supposed to shut down the phone before this happens but the critical voltage is not exact. This is why it is not recommended to empty the battery regularly.

Just in case you are wondering, I just bought my Nokia lumia on the 15th of November, and had to do 2 soft resets, becuase I let it die out in my bag. So yes, I do face the same issues, and I think it should be returned to Nokia and changed.
