How to differentiate your battery from "still-charging" and "full-charged" ? The "electric" logo beside the battery logo are not shining/flashing in iOs 7 beta 6.
So is that consider a bug that apple should've fix but yet to fix?
turning the % on don't show trickle charge
It's probably not a bug. I don't see how it could be.
You are correct and it is an annoyance not knowing when the charge is truly completed.
Even without the % indicator on ... when phone is locked and charging , you press button to come out of sleep, it blinks the current % quickly on lockscreen saying like "87% Charged" . etc ... so you can actually still see if its 100 or not
make no sense as well, when you're at 100% doesn't mean the battery is fully charged.
Just wanted to chime in and say I got 10 hours of battery use and 12 hours of standby on beta 6. I'm pretty sure that's the best I've ever gotten.
