hello,
I have a problem, been playing with lollipop lately, worked fine till I experienced my first sudden switch off and now the phone won't start until it's connected to the usb charger or the dock, once I unplug it it goes off instantly or after a few seconds and can't boot properly (it tries and switch off after a few secs...)
I tried to flash other roms and factory reset , nothing changes...
(i had an issue with the phone being drained entirely and tried to boot several times)

what is strange is that when I'm in recovery it won't stop that way.

what do you think?

I have the same problem!
I am running C6603, Unlocked bootloader, Twrp latest, and cyanogenmod 11 4.4.4

Does anyone know of any kind of solution to this so called " battery bug"?

Sometimes when I use nandroid app to boot into recovery, then reboot to system from twrp (while connected to charger), after adroid has booted I can then only disconnect charger and the phone will stay on for 10min or more if not used. Accessing camera app phone dies immediatly... Seems like as soon as the phone requires more power from the battery the phone dies instantly...

I also used a battery drain app after following reboot steps above and tried running the app while phone was disconnected from charger... As soon as i choose vibrate, cpu or blutooth phone restarts imediatly. While only selecting brightness option phone will stay on for 1 - 5 mins before going off.

Hopefully someone has found a solution or work around... Fingers crossed..!

Oh and one more thing....

While in twrp touch recovery i can use the phone while disconnected from charger.
Only when i try doing a backup in twrp (more power usage required once again) the phone dies.

Hope this helps?
