Also had a sudden death while not using the phone and with around 75% charge left. Tried every tip and trick know to mankind but it kept silent. Then i red about a "new" trick. I will discribe it as best as i can. first hold the volume down key in for about 30 seconds. After that try to hold down the power and volume up key until you feel three short vibrations. Let go of the keys and immediatley plug in the micro usb power. This can work but it didn`t do the trick for me. I did it slightley different. I kept holding down the power and volume key and kept holding it down while at the same time plugging the micro usb in. I got a constant blue led and when i pushed the power button the z3 started to charge. when it was full i hit the power button again and YES! it came alive. I almost had given up hope.

Hi, everyone! I have a problem with my two years old Z3 compact. Few days ago I've noticed that the phone battery drains too fast: full-charged battery dropped to 40% during night at idle state. After few days phone just turned off and I couldn't turn it on. I've replaced the battery with a new one, the phone turned on, but after 5 hours it totaly drained the battery and not turning on again. So looks like the battery isn't the problem. I run out of ideas, does anybody know how to fix this?
