 Newbie here: I installed stable and rc-proposed around 2/1/2017 (sorry, can't get ••••••my phone to give me the version), and I notice the battery loses charge very rapidly, even if I "power down". I put that in quotes because after power down I can still see the backlight glowing away. Any ideas?

 Yes it seems to be a problem that is yet to be solved that others have. There is a bug reported here: https://bugs.launchpad.net/ubports-android/+bug/1610707
