if i turn my phone off and plug it into usb port the usb charging light will come on but the phone will not charge
i have tried this 2 nights in a row now

but it will charge fine if it is powered on

anyone else ?
 
Why are you turning the device off? USB won't charge if the battery is already too low.
 
Plug it into usb on your desktop or laptop, when menu opens, what mode are you in? PC,charge only,USB mass storage?

well when i plugged it in it was on and at 40% charging fine
not sure how it turned off that is how i charge it every night and have not had any problems before
 
The phone needs to be on to charge...

If it's dead and you use an AC charger, it will turn on when it has enough charge.
If it's dead and you use USB it will NOT charge.
 
I just powered my phone OFF waited one minute and plugged into wall charger. Got M logo then giant green battery with percentage displayed and it said charging. When I unplugged it I booted into cwm.

USB does not provide enough power to charge the battery if the battery is in a low or dead state. You need to use an AC Charger.
 
I was curious so after I took my kids to school I powered my phone OFF and in charge only mode plugged it into desktop usb. Phone woke up and booted all the way to lock screen. Fyi. I know it doesn't solve your problem, just sayin.

If you can charge it from the wall, charge it to 100%. Unplg charger right away, boot into cwm and wipe battery stats. Go to applications and clear cache and data in you battery manager. Then see if it will charge on usb after it runs down a bit.

When you plugged it in to usb at 40%,on and charging, what type of a load was on it. Do you have it running overclocked while charging? Cause that usb, as the other poster has duly noted, don't put out a lot o juice. I've read posts where people have run batteries down on usb tryin to charge a pumped up phone. Not making any accusations...just trying to help pin it down.
