Here is a trick for all motorola xt912, xt907 i have check on both working.
Go to setting >about phone>status battery status shows not charging now
just plug your usb cable in pc take micro usb side in your mouth and make it wet (its not a joke) and insert in phone port you will see status change to charging (AC) . Its working for me about two ago and i am sill charging my phone via this method.

So I went out and bought a 2nd USB cable to leave at work to charge my phone. But for some reason the USB cable I bought doesn't charge the phone...instead it drains the battery..??? The light is on and the icon shows it is charging when I have the USB cable connected and I can even mount the SDcard with it. But the battery percentage slowly goes down. The USB cable that came with the phone works fine without any issues.
Is there something special about the stock USB cable? Do I have to buy a certain type of cable to make charging work?
I bought another two cables, even used a Motorola USB cable but never noticed that... it never happened to me.
My guess is:
Fact:
- charging through the pc USB port is so slow, to get full charge you need 6-8 hours compared to 1.5-2 hours through the wall..
Scenario:
You are using your phone or running heavy application while charging it so it drains more battery than charging ..
Just a guess.

1. My phone never charges when the phone is completely off. It seems to only charge when in Android. Is this normal?
2. How do you enter that rapid battery recharge service mode from the boot menu's? The mode I'm referring to is when the phone has not booted Android but all it's doing is recharging the battery with the screen off. If you press the power button, the screen turns on for a second showing you the battery level.

I decided to try a USB wall charger and it's now showing that image of a battery.
Do you ever see that battery image when you plug the phone into a PC USB Port? My PC has decent powered ports (almost 1000ma) but it just won't charge the phone when powered off. But charges when in Android.
I basically only flashed a retail ROM and updated the Radio.
Something to check into is the USB cable that you are using...swap it out with another one.
Speaking from experience with a different Android (DInc), I know I have plugged it into some cables that provide just power via USB (no data) and then I am guessing there is the possibility that there are some that provide data and no power.
The USB cable is perfectly fine, I tried another cable anyway and the same thing happened.
I tried three PC's including a Desktop with decent USB ports, none of them charge the phone while turned off. I tried two USB Wall Adapters and both can power the phone while off.
So it seems that if the USB Port cannot supply more than say 1.5Amp or 2Amps (basically all PC USB Ports), it won't go into battery charge mode.
I am having a strange issue on my Xperia S I would like to know if this is impacting other people. I am running Build 6.0.A.3.67 (FR) and when I charge my phone through the USB Hub (externally powered) it will actually begin discharging instead of charging in certain circumstances.
Here is how it can be reproduced:
1) Plug phone into USB Hub with PC (W7x64) in Standby mode - Phone will show as being charged by AC and battery will charge without issue.
2) Wake PC out of Standby - This will cause the Phone to switch from being charged in AC mode to USB mode but phone seems to continue to charge.
3) Put PC in Standby mode again - Phone will stop charging and will actually begin to discharge at a very fast rate 5% / hour.
To check actual charging status (charging AC/USB or discharging) go to Settings -> About Phone -> Status
To get the phone to go back to AC charging status it is necessary to unplug the USB cable from the phone and re-insert it and it will go back to charging in AC mode. It seems there is something in the phone software or kernel that blocks going from USB mode back to AC mode without unplugging the USB cable.
I have tried 2 powered USB hubs (D-Link and Dr. Bott) and same issue with both. I have tried 2 different USB cables and tested the same steps using my HTC Desire and Flyer and issue only occurs on the Xperia S. 1 difference is the 2 HTC devices always show USB charging mode and never AC but they continue charging without issue as PC goes from Standy to Actve to Standby again.
Can someone else please try to see if their phone also behaves the same way when following the steps above? Does anyone have any suggestions on how to fix? My only option currently is to charge only with an AC charger and not with the USB cable connected to my PC USB hub or I can wake up with my phone dead in the morning.
Thank you for any advice (sorry for the long post)
Hi, i cant charge my photon and pc does not recognizes it. I tried red wire and black wire to charge the battery it worked for battery charged about 50 percent but again when i plug charger it does not charge and also no usb conn. Pls help me
Hi, please stick with me a minute!
I was gifted (elderly, but usually savvy aunt) an early droid razr after battery fail (and verizon replacement to a newer phone).
I was given an XT912, with 98.72.16.XT912.Verizon.en.US installed.
Also: cable marked: Motorola Data Cable SKN6428A 12150-0403532 and
double usb wart, folding prongs: SPN5689A 11268-C6-0821306-13D1 DC4050US0305.
It would only run when I pinned an USB cable directly to the battery terminals.
Battery would not charge, so I ordered another.
Now, new battery is in, and it will run from battery (still open back).
Wall wart/cable shows NO indication it is charging - white LED blinks on insertion (often starts), and that is it - no other lights, no charge icon, no charge text (Battery applied voltage does not change.).
USB to to computer shows no lights, DOES show charge icon, DOES show charge text (I can see battery applied voltage go up a bit with meter).
Is this all normal?
Is it the right cable for wall and USB use? Was there only 1 in OE box?
(I'm very suspicious because this cable/wart WILL charge my N7, but not this droid razr.)
Is there a special cable for wall wart? Pinout?
(I tried re-flashing existing OE rom, same results.)
THANKS ANY AND ALL!
OK, I flashed a couple of more times, and now I get a steady white light on wall/usb insertion, still no charge icon, no charge text.
Is there supposed to a (while off) charging screen? After short push?
