When I plug in my RN3 Pro Prime I get no indication that it is charging and it gets very, very hot. It was charging okay a couple of minutes ago and now it isn't. When I plug it into my computer it gives me a USB device malfunctioned. Help?
Perhaps you have a defective device.

i lost the original cable so ive been using a mini to micro usb adapter for an old cable i had for my g1 which hss worked perfectly.
thought i had broke the sockey on thr phone. had a tmobile shop check it with there cable. it was fine. so boyght a microusb cable.
everything seemed fine. charge light. usb drive worked internet tether. but then the phone ran out of battety while usb tethering. it always stays at 100% before.
with the battery low it woukf rrstart every minute whole plugged into original chargrr.
its charging but very slowly. 15% in 2 hours. checked battery pins. seems fine. i dkd manage to get 37% charge in 30 monutes once irh the phone off.
the phone doesnt even get warm while plugged in. it used to get pretty warm when cuargibg.
tried hard reset. trief reflashig rom. it knows wall charger is in. says charging orange charge light.. but it charges sooo slow...
im stuck. is this a repair jobk
Just got home and tried the new cable in my home PC. ive already lost 1% battery in the space of a few miutes usb tethering....
make sure you have the "don't charge the phone while connected via usb" unchecked. Other than that, sounds like a hardware problem.
i cant find that setting, only do not charge when the phone is on., which is off. Ive just noticed something else. the brightness setting for AC power effects the brigthness when connected to usb. I dont think it knows the difference between ac and usb anymore.

when you plug it into the wall, do you get the menu for: Activesync, Disk Drive, Internet Sharing? If so, then this is true. Really sounds like a hardware issue. I would take it back in and see if they can replace the port.
nope, when i plug it into the wall, no menu. it does seem to know the difference between usb and power. as using the option "when phone is on, do not charge when the pohone is connected to pc" has no effect with the wall charger.
I tried a different wall charger. I have a travel charger which is only rated at 500ma instead of 1amp and it charges the same. I was able to get 100% overnight. woke up after 8 hours to see the green light on, it stays at 100% with the wall charger as long as you leave it alone.
back into the computer, tethering and im loosing battery as if it wasnt connected.
Looks like ill have to dig out my insurance as its not a warranty repair (and also the water damage stickers are red, due to it being dropped in the toilete 3 months ago)
hmmm interesting. phone has been in charger overnight and was at 100% when i got up, pluigged into pc for usb tethering, despite battery dropping the green light is still on.
Ive done some searches on usb micro cables and came across people having problems with some data cables with charging, as some cables cannot cope with the large current required, but they mentioned that there phone would say this and i have seen that on my phone before with my front usb ports on my computer.
Im gonna order a microusb adabter as i have 2 high qualiity usb-mini usb cables from a G1 (which was usbed with an adapter with no problems) and 1 from a tmobile mda varia, same cable.
This has now been solved. After closer examination of the USB mini to micro adapter, it apeared that the 2 outside pins (which are for charging) had been flattened. Looking at the adapter, you could only see the 3 middle pins, but with a torch you could see that the oiutside pins were compelty flat. from droping the phone its oviously twisted the connector resultinin in flatting those pins.
I went back to tesco and bought the same USB kit which comes with a mini USB cable and several converters to fit different phones.
AFter hooking up the cable and micro usb adapter to my PC, my phone was within minutes showing increase in battery charge. After a few hours with usb tethering enabled and watching videos online im up 2-%.
The cable i bought for £7.99 which is micro usb though doesnt mention any HTC phones (mostly nokia) will connect perfectly for data transfer and the phone appears to say its charging. It looses power suggesting insuficient charge current. Maybe its the rom im using disables thsi warning as i have seen this before when i connected my phone to the front usb ports, but it works fine with the back.
So, it seems i have not damaged anything apart from the usb adapter i was using.
All is well, and im charging at a fast rate with USB while tethering.
Please close this trhead as it is resolved.
Final update. After several days i have been usb tethering and charging absolutly fine. Using 1amp charger charges fast!
Even from a dead battery can plug into usb and have the phone bootup.

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.

I've had my leMax2 for just over a month now, as of yesterday I noticed that the phone was not holding charge. If I unplug & re plug, it will start to charge again, then after I while, it either stops charging or is very slow. Not been able to charge over 30%
Fast/normal charge makes no difference.
Has anyone had this problem?
I've ordered new USB C cables, hoping that's the fault.
Weird, I connected s9+ to computer and tried to copy files, but it said no files on your device
So i tried multiple times reinsert usb plug. Suddenly device not recognized. Suddenly it stopped charging too. Went to shop and they tried wireless charging, but said ''no response, negative charge''
Im on android p and had 5% battery left, backed up some stuff by copying to external sd and then i wanted to look for enable wireless charging options but no battery left....
If i connect via usb lightning icon appears then black, no charge, sometimes water warning
What could be the problem
Once find that usb on the phone end gets really hot while plug into my laptop. Glad to realize it and pull it right away. Maybe yours is too late and broken the charging port. I suggest go to Samsung repair.
Ok so I started having a weird charging issue with my Xperia Z2, a few months ago when I plugged the phone in to charge and noticed it was constantly showing it was charging and disconnecting non stop (basically this here Xperia Z2 charging disconnect)... first thought was maybe my usb cable (original Sony cable) was buggered but nope, plugged in my Xperia Z5 on the same cable and it charged fine, so I tried my magnetic charger on the Z2 and nothing, no charge at all. Eventually when the phone died completely then I was able to get it to charge but not without some issue, when plugging in it would still do the same thing, charge and disconnect constantly, it would take unplugging the cable and plugging it in again a few times till the phone would eventually charge and even though the charge would show 100%, when I turn the phone on, the battery percentage would vary anywhere between 80%-95% and it would discharge very fast.
I figured it may have been my battery as I have been using the phone with an expanded battery since like 2020 and thought maybe thats it for the battery. Eventually got around to getting a new battery this weekend and the phone still does the same thing but its a bit different now, connecting it with my Sony cable still did the same thing when connected to the wall charger, charge and disconnect constantly. Then I thought maybe it could be a software issue so I connected my phone to my PC using a different usb cable to copy some stuff to my PC before resetting the phone to see if that helps...connected it and it was charging...so I take my Sony cable and connect it to the PC with that and it was charging...unplugged the cable from the PC and plugged it into the wall charger and it was charging and disconnecting again. Plugged it into the PC again and started charging. Tried the other usb cable with the wall charger and it did the same constant charging and disconnecting. I know the wall charger is working fine as I am charging other phones on it too with no problems.
I try a third usb cable on the wall charger, this is a real cheap low amp cable, my Z2 starts charging with it almost normally, painfully slow but it was charging. Now I say almost normally because when it charges to around 90% then it starts doing the constant charge and disconnect again. Also the battery doesn't discharge as fast as it was doing before but still a bit fast.
I want to try flashing a new rom, stock and custom to see if any of those might work.
Would any one have any idea of the issue or experienced anything similar and was able to fix it? Any help any one
In the past I had a similar problem, try to clean the Usb port on phone and try again.
Kindly regards
I remember reading something about the live kernel being involved in charging. It makes sense for this to break charging while completely empty. To charge at full speed you need the kernel to be running, but to get the kernel running you need power, the trickle charge you get without a kernel isn't enough to keep up with the boot process, so you end up in a loop of no power. I have not tested if another kernel fixes it, but it is currently broken on my device.
