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.

Hi everyone. I own a GS3 that has been running flawlessly for about 3 weeks but since last 2 days it has developed a problem whereby it only charges via the laptop USB port and not the wall charger. I have tried factory reset, flashed two different custom ROMs based on two different firmwares, pulled battery many times, etc etc, to no avail.
the phone starts charging from wall charger, but after a few minutes, charging stops. I have used the original Samsung charger, my old HTC charger, with a combination of many different USB cables and the result is always the same. The USB port appears to be undamaged
ny suggestion to fix the problem?
Android 4.0.4
I9300BWLH1
Kernel SIYAH S3 V1.5.2
Well from what i can see the problem doesnt lie in the data cable. So maybe it the wall plug section. Or maybe the the socket itself maybe be faulty.
Problem doesnt seem to be in the phone itself so nothing to worrry about too much.
Maybe buy a travel charger to see if that helps.
Also high recommended that you do check the plug socket to see if anything else charges in there.
Might be worth charging in a different plug socket.
Hope this helps

the data cable IS OK !!
How about the plug socket. Have you tried to plug something else into the same plus socket to make that it still charges for example plugging your laptop into that same plug socket that your phone was to see if the laptop charges.

the result is the same.

Well I thought my phone was broke last week...
It wouldn't charge so I tried my old HTC charger and that wouldn't charge it either but it would via usb to laptop. So I purchased a new wire and that worked, I then tested my HTC charger on my HTC Desire HD and that still worked.
So the SGS3 doesn't seem to charge using a HTC cable unless connected to a computer. Try purchasing a new genuine usb cable
Alternatively, you could wipe battery stats in CWM (in advanced menu) and see if that fixes it

I had the same trouble, only 3 weeks after I bought my SGS3.
I did go to Samsung repair center, and they change the motherboard (under warranty).
2 Month before, same trouble with my SGS2, unfortunatly no warranty.
Samsung ask me for (around) 300$ for motherboard, and I did not do.
I've removed batterie and charge with external battery charger .... and forget it a while.
When I try it later, it was working fine ! What was my surprise !
I can charge it again with charger.... two days after "same player shoot again" : impossible to charge ... then work again :silly: !
I'm having this issue too. There is a whole thread of people having charging issues, and I assumed my problem was the same, however upon further inspection it charges via PC USB cable. That said, this may be the issue with the others in that thread.
My phone definitely seemed to charge by powerpoint when I first got it, but has since stopped.
Charging by PC is a pain, as I use my phone as an alarm, and my PC is in another room.
edit: the lightning icon comes up when I plug it into the wall charger, it just gets no charge. Is this the same as everyone else?
Hi
I have about 6 months old Galaxy S2.
Since yesterday I've been having trouble getting it to charge. Connecting a charger while the phone is on or trying to connect it to the PC doesn't do anything. I've tried different cables and charges (ones that used to work until yesterday).
The only thing that gets it to charge is if I remove the battery, connect the charger, insert the battery. After it runs on its charging fine.
Do you think its a software or hardware issue? Anyone had similar one?
Thanks
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.
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.
