Given my charging issues, I've been paying a bit more attention to the #librem5 #dogwood battery behavior. It seems that turning the device off with the battery still in it, will still drain the battery. If you want to keep a (in my case hard-won) charge you have to pull the battery out too.
At least you can? Removable battery ftw? Nah, this isn't a win. But it helps.
I just left it powered down for 2 hours - lost 9%. Will try again when it’s repaired.
