@messayisto I tried, but it didnt work

@donieck I have reinstalled it via ubports-installer (RC channel). There is some kind of problem with the DEV channel build. Recovery works - hold power button, after the screen is restarted, release power button and hold volume up button until warning about unlocked bootloader appears, then release volume up button and wait for recovery.

@arubislander I has read it. I removed the config files of dekko2 in upstart .cashe, but it didn't work. I change the upgrade channel for develop, and battery time is 24 hours after charging. Thank you very much for help

@donieck do it in two steps?
