My Lumia 920 can charge itself even if it runs out of battery and turns off automatically. Plugging the charger cable will first make the phone boot to the AT&T screen and the black charging-icon-only screen. About 5 secs later, it will reboot and show the start screen with charging icons at top right corner.

However, today I was watching video with a Netflix-like software until the battery is empty. When I plug in the charging cable, the phone stuck at the charging-icon-only screen with one red bar showing in the battery. It won't boot to the start screen again! Anyone has had the same problem?

Yes, Basically what has happened is that the battery does not have enough charge quite yet and will not boot the OS until the battery has enough charge... Plug it in and let it sit.. This is normal and even WP7 devices did this if the battery gets "too low".
Plug it in and let it sit.. After awhile when the battery reaches enough charge it should boot.
Good Luck.

What you said is absolutely right. After 20-min wait, it now can boot to the start screen.

I believe that the OS has to have a minimum charge in the battery to boot .. Once the battery is ran that low it takes a few minutes to charge before it will reboot. Glad it's now working for you.
Take Care,

Mine did the same thing but instead of booting after a bit it just gives me a little red bar a plug flashes then it goes to a quetion mark. I have had it on the charger for 4 hours. Any help?

The same thing is happening to me right now, do I need to do anything? Have you found out how to turn it on then?
