I’ve got a new phone & battery, haven’t seen any drain with the power off.
Satisfied Pinephone & Pinebook Pro owner.
Thank you PineTeam for your outstanding work!
I am now starting to suspect this is a software issue. For the most part I have been using UBPort's Ubuntu Touch as it seems most things on the phone seem to work best with it, however no updates in over a month.
I do have an image of the Manjaro with Plasma. I booted it up yesterday around 3PM local time and did some updates. I played around with it for a while, then tossed it to the side, forgetting to plug it back in for charging, as with Ubuntu Touch the battery would be dead in about four hours.
I grab the phone this morning, and now over 18 hours later, the battery charge is quite high. By the time I tossed the phone to the side it was about 83%, and now showing 74%.
Another data point, I just turned my Pinephone on after being turned off for nearly a week with the battery installed and after booting up the battery is at 96%. The battery was at just about 100% when I'd turned it off but I'm sure the boot process consumes a bit.
