Is there any way, whilst charged, to fully power these devices off without them continuing to drain the battery?

You can fully power off by holding the power button for 5 seconds. That reduces battery drain but not tested how much. @jpsmilli

I know you like your Roam Ken and certainly get more life out of it than most/any but 1-2% drain per day on a powered off li-ion device is way higher than normal (and most seem to get more drain than that).

If I fully power off my tablet it will be on 99 or 100% a week later. Always.

Funnily enough I just bought a battery ‘boost' thing for the car as it struggled to start sometimes through lack of use.  They claim it should be on 70% after 12 months.

Unfortunately I’m away from Home for a family Birthday party tomorrow night and my Roam is not fully charged at the moment, but what I will do next week, when I get chance @sjw is I will charge my Roam to 100% take a screen-grab showing the time/date and power it off and will switch it back-on 24 hours later and take another screen-grab showing its battery loss - you’ll just have to take my word that I haven’t charged it in-between. My experience when I first had the Roam and did that test was I was losing on average 2% per day  …and I have no reason to lie about the battery-loss I saw in those tests.

The self discharge rates are mentioned in this Wikipedia article and this of course is dependent on environment temperature…

i will just leave my powered off Roam on a table in the Dining Room, but you’ll just have to wait till I get a chance to be at home to do this.
