Any/All observable changes please.

Note: The K4 is the glued together model, difficult to open, next to impossible to get old battery out without destroying something.
It's just charging with orange led indicator without getting green (I left it for night).
Also I found that in Fastboot mode it getting charge faster, so after night charging on wall cherger, I left it connected to USB and after couple of hours it becomes green.
Now I'm trying fully discharge the battery with LED light on my Kindle case. It lights pretty long, so I'm really doubt that problem in battery.

Update: when it completly discharge, device showing on screen standart picture about empty battery and to connect to electricity.

Update 2: we already opened back cover and get to the battery Yes, we loose two of four plastic latches.
