For those who need to see the percentage, how about just checking the top bar for the battery %? Just swipe down, take note and swipe back up/lock screen
Yep, that's exactly what I've been doing, since moving from 8.1.
It's not a bad way to do it, but it's one more swipe, after unlocking, or whatever. I wish MS would fix whatever the issue is with having a tile update; 15 minutes would be great, anything for at-a-glance-percentage.
I finally uninstalled my "Battery" app, which had been so dependable, on .318, since it was often saying things like 47%, when it was 100% for several hours, and sometimes 99%, when it was down say at 38%. Yes, I had it background enabled, just like on 8.1, but it never seemed to get a time-slice, unless I opened, or maybe once or twice a day, otherwise. Sometimes it would sit, same number, all day long.
I think it's all my math/CS/physics background, something like "it's somewhere between 1/2-maybe-3/4" bugs me. It's good for a fast glance, but annoying otherwise, IMHO ;-]
