My Motorola RAZR V3 has suddenly stopped charging. It displays an 'Unable to Charge' message on the home screen or the battery icon just disappears completely! However, when I plug the mini-USB charger into it the the phone lights up so it does recognise something is plugged in. I know it isn't the battery as I've checked this and tried swapping with another V3 and it works fine and the other phone's battery makes no difference to my phone. When the battery icon and 'Unable to Charge' message is displayed I've noticed a new icon appears next to the battery one at the top right-hand corner of the home screen. I don't recognise it but it looks like a phone with a straight vertical line either side with 2 chevrons (^ but facing inwards) about 1/4 way from top & bottom of each line. Otherwise the phone works perfectly!!!
- I HAD THE SAME PROBLEM WITH THE "UNABLE TO CHARGE." THE PROBLEM WITH MINE WAS THE FOUR PRONGS THAT THE BATTERY CONNECTS TO IN THE PHONE. ONE OF MY PRONGS WERE STUCK IN THE DOWN POSITION AS IF THE BATTERY WERE THERE. ALL I DID WAS USE A KNIFE AND POPPED IT BACK IN THE OUT POSITION. THEN I TRYED TO CHARGE MY PHONE AND IT WORKED PERFECTLY.
- Had the same problems, my phone said unable to charge and invalid battery and I took a baby wipe and cleaned the pronges in the phone and the battey and then took a tiny screw driver from a class repair kit and popped the prongs in the phone up in even position and the phone started charging, I havent checked it yet to see if there is anymore problems going on because I have it on the charger now but hopfully it will work ok..
- I just came here with the same problem.However, when I plugged in the charger after removing the battery, it did nothing. So I tried to gently clean the battery terminals, and put it back in the phone. It started charging right away. I used a tiny bit of optical glass wash to clean the terminals, and a very soft cloth. Hope this works for you!
- I personally found, after having tried cleaning the contacts for the connection from battery to the phone, making sure that the contacts were making contact, blowing out the back of the phone, and all else, that the solution was as simple as using the actual Motorola charger. Doesn't make a lot of sense to me, but I found the charger, plugged it in, and I got 'battery charging'. Thanks everyone!!
- it is hardware problem it will be helping if you have multimeter an check its batery conector whether its second pin to gnd is gronded or not if it is grounded then there 5 pin chip contaning bridge of diode replace it
- I had this problem after my phone had gotten wet. I had polished all of the contact points with a straight pin, but still was "unable to charge". After reading about using glass cleaner above, I decided to try the tape head cleaner and swabs I use for cleaning my camcorder. Instant success!
