Have you tried a battery pull?

 

That doesn't sound normal. From 0%, the phone needs to charge to about 10 to 15% before it can power up again. This shouldn't take no more than 10 minutes to charge though if plugged into the wall. The only time (for me) when it charges slowly is via USB into the computer which barely charges the phone but at least keeps it from draining. Since you are plugged into the wall, I'd just pull the battery and see if that works.

 

Try taking the battery out for a couple min. Then put it all back together and plug in in the wall charger (usb won't work) for 20 min and see if it turns back on. My brothers droid did the same thing and he had to use a wall charger because the usb wouldn't charge it (for whatever reason)

 

try plugging it into your USB on your computer - had something similar happen with an mp3 player one time. it wouldn't charge via the wall charger, but as soon as I plugged it into the USB, voila!

 

That worked for me. I just had the same thing happen and this resolved it...back to normal.

 

I may have misread while going through the posts in this thread, so I apologize if I'm repeating a question and/or suggestion.

Janitor, have you tried taking out the battery and plugging the phone into a wall outlet? Try powering on the phone via direct charger feed, without the battery present. If you can turn it on fully without issues, with the battery out, then you know it's the battery and not the phone. If the phone comes on, place the battery back into the phone with it still powered on and see what happens. If the phone still won't come on while plugged in with the battery removed, then it's most likely a problem with the phone and not the battery.

Whatever you do, try to at least get it back on and at the homescreen so you can un-root the device if you end up needing to. Verizon will actually probably not notice that you're device is rooted if you end up having to take it back, but it's definitely a good idea to erase all traces of a root when taking it back, if you can. Better to be safe than sorry.

 

I'm having the same problem. Wife was playing a game yesterday for 3 or 4 hours with screen at 100% and got a 15% battery warning, but I had to wait for her to finish (20 minutes) before plugging it in. Using her mot charger (different phone, but worked before), it quickly charged to 40%, but seemed to stay at 40% for some time before I unplugged it to go for a 2 hour walk with the gps on to track our route.

Received 15% warning sound before arriving home and quickly plugged it in again, but phone never charged. Pulled the battery and replaced and still would not charge. Saw 15%, then 10%, then the battery low prompt kept coming up like once a second so shut the phone down and let it charge all night. This morning, never saw more than the moto logo when trying to power it up.

Plugged into the usb on the computer now, no tone, Windows doesn't show it plugged in and can't power up the phone. Did have a green LED light on the phone for a bit, but playing with the power button to try to boot turned that off and it's like a brick now.

I suspect I'll have to see if Verizon is open today (I'm out of town). Had an extended battery on BO using the coupon code. If they're going to give me a replacement battery, I'd rather it go toward the extended battery, but not too keen on paying $50.

I wonder what happens if I borrow a coworker's X battery long enough to power up the phone and while connected to a charger or usb, hot swap with my batteries, if it'll charge then? I've only seen a 15% warning once and didn't have trouble like this.

 

Just tied starting the phone w/o battery and got to the lock screen and received a warning about battery not found and it powered off. I tried a second time, thinking I would insert the battery during the red droid animation, but it wouldn't come up at all.

 

I swung by Verizon before leaving for home and the tech said I had a bad usb connector and ordered me a replace phone. I'm hoping I can get a good enough connection to charge up my battery (or swap with a co-worker) long enough to remove personal info and settings. Should have a replacement X on Wednesday.

I see I have 10% on my charge already so apparently my cables at home are better quality than the ones on my trip.
