And asking for confirmation on battery observation.
I use 2 Jollas, one only for private calls (~5 daily), screen almost always switched off, wifi/bt off.
On 1.1.7.x it lastet max. 4days, now with unchanged usage pattern i charged it twice since 1.1.9. early adopters update of that device 9 days ago, and still power left. (Battery log activated on second charge, out of interest to confirm 5 days first charge duration)

EDIT, battery is a new polarcell replacement
