Hi guys! I have a USB problem that's been haunting me for over two months now and I still don't have a solution.
After the repair center refused to replace my broken micro-USB connector under warranty because of alleged water damage, I decided to do it myself and ordered a new connector on eBay. Once it arrived I was discouraged to carry out such a repair myself by my uncle, who is quite experienced with micro electronics, and that he would do it for me.
I gave the phone and the new connector to him last Saturday and he had done the repair by Sunday evening. I went to his home to pick it up and found it charged to a full 100%. However, when I came home and after some usage wanted to plug it in again for the night, I could not get it to charge from my home charger.
I've tried the following:
-LG wall plug with LG usb cable (came with the optimus pro that I'm using as a temporary phone)
-Dedicated aftermarket 220V to micro-usb charger (good quality, not the cheap chinese kind)
-NS original USB cable connected to computer
-NS original USB cable connected to LG wall plug (different that the first mentioned wall plug)
So far the first two were unsuccessful and the latter tow only work if I pull cable to the right, while the phone is off. I have not been able to charge while on. An expectable reaction would be to buy a new charger because probably all my chargers and cables are broken, but the strange thing is that they work perfectly on the charm. The phone can not be the source of the problem either, becauee it was charging fine at my uncles place.
What possibility am I not seeing here people? What am I missing?

So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks
Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.
If you are in the US Office Depot sells the charger and USB cable for $30.
strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.
Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.
Sent from my HTC Sensation 4G using XDA App
Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.
Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.
I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.
Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .
Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.
I purchased an original HTC car charger a few months ago. yesterday I noticed that it wasnt charging my phone anymore. The tree letters "HTC" did light up so it had power. I tried another USB cable and it did charge again, so probably I have a broken wire somewhere.
I bought the original HTC because I heard rumours of phones not being charged while using a lot of resources. It actually did charge but couldnt keep up with the power demand.
Can anyone conform this or can I use any universal USB cable?
Hello
I am not sure how to properly explain this but hopefully someone understands what is going on.
My Nexus S (i9020a) doesn't charge properly. The original Micro USB cable that came with my phone frayed and no longer works so I went and picked up a third party one for $20. For some reason my phone will only either charge on an angle or upside down with this charge cable.
(It isn't the cable its self it works perfectly on everything else Micro USB wise)
I do find it weird that I originally thought it was the USB port on the phone that was dying so I cracked it open and there seemed to be no sign of destruction on the board so I put it back together. I then plugged it into my Nexus 7 Asus wall charger with the Asus cable and the phone charges properly no angles or upside down.
Any suggestions besides buying a $24 charger from Google?
Things I have tried:
1: Different wall chargers
(Nexus S wall charger + 3rd party M-USB):crying:
(Original Galaxy Tab 7.0 Wall charger + 3rd party M-USB):crying:
(Asus Nexus 7 wall charger + Asus M-USB):good:
2:Cracking the phone open to check the usb port on the board.
Phone: Nexus S i9020a
Carrier: Telus
Rooted: No
Version: 4.1.1
PS: Let me know if you need anymore information.
The thumbnail below is what I mean by Charge on an angle.
I doubt opening your phone will show you if the usb port is broken, unless you opened it previously. The most likely problem is that your USB port is worn out, dirty, etc and it's having trouble making contact with the cable ('charging at an angle' is usually caused by this). My recommendation is to try to clean it. First power off your phone, then try sticking something that can scrape the little metal pads in the usb port. Be careful that you don't bend or snap anything inside or outside the phone, so be very gentle.
Another possible reason, which is a problem I've run into myself, is that the charger you're using just doesn't work with the phone. My Nexus S doesn't charge when I connect it to a generic USB charger in my car, nor does it charge with most wall chargers and the original Wall charger that came with my phone was DOA. The only way for me to charge my phone is at my computer or with some wall chargers that, I guess, output more amps (I'm noob when it comes to electrical stuff! ). If it doesn't charge in one USB port, try connecting to another one and/or switching cables.
If it doesn't charge at your computer, then it's probably dirty.

Thanks for input.
I don't think the plug is worn out since it works perfectly with my Nexus 7 charger. I did look into the bottom of the phone and it does look a little dirty so that could be a small part of the issue but that doesn't explain why it it would work perfectly with one charger and not another. It does sound like it could be just the wall chargers I am using are not as good as the Nexus 7 charger (When I use the nexus 7 cable and charger the cable seems to fit alot better and it very firm when it is plugged in where when I plug in my 3rd party cable it is loose and feels like it is going to fall out. I might just buy the extra asus charge set from google since I know its a 100% work rate. was just hoping I wouldn't have had to spend that on just a wall chargers. >...<
Hello everyone,
Since a google search did not reveal other people having the same problem, decided to ask around here.
Purchased the Moto G a few days ago and only had to charge it once since then. Really happy with the phone as value for money is amazing.
This morning I used it with Navigation and when I got the 14% left of battery notification, connected my old car charger which worked fine with every device until now. To my surprise, the phone did not show any signs of charging and battery kept on discharging.
Got home, tried the cable that came in the box and same results. Connected the phone to a USB port on my PC and it charges. Tested my old phone with car charger and that works just as I knew it would.
Obviously, there's nothing wrong with the car charger which has an output rated at 5V and 500mA (same as USB port).
Asked moto support about this issue and they advised to turn off the phone for at least 5 minutes and try charger again. This time, when connecting the phone, it just turned on as I had left it turned off and after boot still no signs of charging.
The moto support website states that it should work with pretty much any charger.
Any advice besides from testing other car chargers?

Is it Motorola branded or some other brand?

motorola branded. Around 6€ if I remember correctly
I found an odd youtube clip from an aussie on the road complaining that none of the chergers he kept buying were working, what he eventually did was short out the green and white points in the charger as they apparently are left dead or have resistors on them but you could do the same by splicing a regular cable and twisting the green and white wires to the phone.
tried it earlier and it seems to work, so am adapting a cheapo usb wired charger first then will tinker with some cables.
My Moto G charges on every wall charger except Kobo's, the only 2A one. My generic auto charger has 1A and 2A sockets which both work. I suspect your auto charger is out of spec, 5V +/- 0.25V (USB 1/2). My Walkman didn't like my desktop ports, and support says custom computers may not work.
Wikipedia has a good section on Power (7) in the USB article. Forum won't let me post the link!
sure I have replied to one version of this anyway although a bit late this does come up first in a google.
so the issue is the phone has its floating point thingy locked so it it doesn't work with most in and out chargers even the posh ones only provide power.
so taking a hint from a crazy aussie who was butchering chargers I took a different approach and butchered cables.
the principle is the same the white and green wires in cable or the white and green terminals in the charger need to be bridged or joined together. if you feel the wires are a bit thin to cut into or you like me break them a lot then you can use a USB extension cable and splice that instead.
I chopped off the end off a data cable and patched one directly into a standard micro usb charger where I'd broken the tip and it works a treat as indeed do the other mods.
much easier than hacking the phone IMO.
So not that long ago I picked up a Belkin car charger while waiting for my Google model to come in. I actually never got around to using it and just took it out the box today.
The cable I bought was a "Belkin Car Charger 12W USB-A input + 15W USB-C" from Target.
Anyways to the point. Today I figured I could use the usb-a to usb-c for tethering to my desktop. I hooked it up, ran fine for a little while, then my PC crashed (straight off) with no warning. Powered it back up and got the same thing a few times. I went around changing drives, swapping Psu's, and even swapped Mobo + cpu until I found a combination of hardware that should work.
And it did work, until I plugged my Belkin c to a cable back up for tethering. Again, after 6 or 7 minutes, the PC went straight off. At this point I came to the conclusion that something must be shorted inside the cable. SOMEHOW I managed to find the receipt and swap it for a new one, same model. Guess what? SAME PROBLEM. I still didn't believe it was the cable, so I swapped cables and everything was fine, and even asked a friend to test the cable. When the friend tested it with his type c drive, he immediately got a blue screen (iqrl not less or equal) as soon as the drivers loaded.
Tldr; Two Belkin cables had similar problems and are crashing pc's
the product you're referencing doesn't come with a USB-C cable, at least not one that can be used as a data cable
