After previous test I put device with empty battery to charger and it
happens also when connected to charger (over wi-fi).
Once with wlan power settings 100mw and later also when reduced to 10mw.

Then I closed wlan and connected via bluetooth and no errors on charger.
Then disconnected charger and no error again on battery (grey icon with
1 stripe again).
Then did again still ins same shell via ssh over bluetooth but also
connected to WLAN (but left it idle). And it happened again !
Then just disconnected WLAN and run again is same shell and it was OK again.
So it really seems related to wi-fi.
