K4 K4 discharge in few hours when on screensaver
Hello everyone.
I have a problem with K4 Black. At the beggining I would like to add that I tried Kubrick with all options selected (reformat user store etc.) but it didn't solve my problem.
Kindle is working fine until it goes to sleep. When screen server turn on (no ads) I can immediately turn it off, but if I wait few minutes - the power button doesn't wake it. I can only restart device holding power button for about 20 sec.
If I leave it on screen saver - battery discharge from full to empty in 3 or 4 hours.
As I mensioned - Kubrick didn't help.
I turned off screen saver (;debugOn ~disableScreensaver). Without screen saver it looks ok - battery keeps it's charge.
It looks like something is happening few minutes after going to sleep - I can't wake it and it discharge very fast.
Did you hear about such behaviour? Do you have any sugestions how can I fix it?
Thanks in advance
