first charge - how do i know it's charged?

i haven't yet switched the phone on, and am charging the batter - when i first connected it i saw a little charging battery icon (black and white) but now that's gone.
with no notification led, how do i know when it's charged? i want to play
you will see a white battery with little bars moving
when it's full it will be stopped
that's when the phone is in OFF mode
and obviously if it's powered on, then you can see it in the status bar
interesting, the phone is off, and i see a blank screen now. i saw battery with white bars moving, but not now :/
EDIT: Ohhh! I have to press the power button to see them now! See, the manual doesn't say that, and I didn't want to switch on until a full charge!

[Q] Battery with Loading Circle

I flashed the latest SlimBean 2.5 and turned my phone off. Now when I try to turn it on, I get an empty batter with a little loading circle on it, then the phone turns right off. If I take the battery out altogether I still can't turn on the phone. If I put the battery back in, the empty battery with the loading circle comes up on the screen for a half second, then the phone goes black and doesn't respond to anything at all (up/down + home + power, power, etc.)...
I really hope I didn't destroy my phone...any ideas?

Annoying Battery Status After Unplug

Every single time I unplug my phone from a charging cable a large text box at the bottom of the screen comes on to tell me what percentage the battery is on. Like I KNOW already its in my notification bar.
Does anyone know how to disable this?

Replaced battery, now it doesn't recognize any level

Phone is Moto X 1st gen that had the original battery and was slowly dying so I bought a replacement off Amazon and swapped it out. Now it doesn't recognize any charge level to the device. I've tried a couple of those battery recalibration apps off the App Store but no luck with that (though one of them tested the battery integrity and confirmed it's not a dud). When I swapped out the old battery it was at like 18% or something so upon putting the new one in and rebooting it stuck with that 18%. I read that you could retrain it by letting it drain completely then charging full so that's what I tried next, now it reads zero.
Here's the behavior I see:
Power off device, plugged in to charger. If you push power button it will display a battery icon with a question mark in the middle
Hold down power button in this state and it still doesn't start up but the battery icon switches to the standard lightning bolt 'charging' icon but reads 0%. This number doesn't change.
Hold down power button again and it boots successfully but battery meter reads 0% - charging (actually one of the recalibrate apps I ran set it to 4% so now it says that)
How do I fix this?
