I'd say 2% total battery drain over the course of 8 hours, or 1/4% per hour is GREAT compared to the 2% per hour I believe I saw when I first got my Hi12 and tested a couple times. Because of what I considered high drain when I tested, I've always shut mine down. If that's possible, it seems to indicate only about 25-30maH per hour drain! Now, I'd call that pretty darned reasonable for keeping 4GB of RAM refreshed, which should be the principle drain! 6% a day vs. 48% a day would mean quite a lot. It would then certainly be feasible to leave the tablet in sleep mode for a few days between charges, and possible a little better for the battery long term as I tend to charge mine nearly every time I use it, most often letting it charge while using it.
It would seem that I need to test again to see if any improvement has been made through Win 10 updates. OTOH, I suppose it could have something to do with your fresh install as well. It'd be great if you could figure out if it was a particular driver or settings/combination that allowed you to achieve that low a drain. I'll try to test soon. As always, Motobot, you give us something to strive for! If I don't get decent results it might even be worth a "Nuke and Pave" and re-install with Moto's Update when I find time to do it...
Moto, is there a clear, simple set of directions available for anyone to follow to get and install the update with your compiled install file? Or a further updated version? Link?
