My J7 Pro won't charge by wall charging but when i connect it to my PC, it charges. PC lets my phone recharge but it won't read my phone, even using ADB or connecting through Odin. Tried multiple charger.

problem with charging

hey..
i've got a strange problem...
sometimes i try to charge my x1 via usb cable (outlet). and sometimes via usb cable (notebook, desktop pc etc...)
sometimes first alternative does not charge my x1 and sometimes the second!?
thats really strange and i dont understand why?!
im confused... last night i charge it via outlet and nothing happens...
(
I have had the same trouble. Seems to be something with the USB cable. I have one cable with a blue led in and that cable does not charge the phone. The light on the phone stays on and the batti monitor says charging, but it's draining the battery. A second cable is even more strange, it starts charging for 1-2 minutes, then the phone stops charging and says I have a missing sim.... reboot the phone and it works great again. Bot this cable have been tested with the original SE USB charger and my iPhone USB charger. Same thing with both adapters.
What's even more strange is that both USB cables work great with my Qtek 9100 and my 2,5" USB drives.
When I connected the original USB cable to one of the adapters and the phone it's charging normaly. I realy don't know why this is so...

Trickle Charge

So, i've tried charging my phone via computer twice now and every morning i do, i wake up with an all but dead device. While it says it's charging, it doesn't seem to do anything more than simply keep the device at minimal operational levels of energy. Anyone else experiencing this???
older computers and charging through a hub will cause this.
with my focus, it takes about 3 hours to charge fully using the computer or about 2 hour to charge using the included charger.
This happened to me last night
I have now had my phone 6 days. Each night, I have charged it by plugging into my computers USB port, so that I can sync that days podcasts. On each night, it has fully charged by the time I wake up in the morning.
This morning, I unplug the phone from the USB cable, and I notice that I only have one bar on the battery meter. I checked the USB cable where it plugs into the computer, and it appeared OK. I unplugged the USB cable from the computer, attached it to the wall plug adapter, and plugged it into the wall outlet. After about an hour, it looks like it has charged a bar or so.
So, maybe I just didn't insert the plug very well. Maybe. Crap.
Most PCs turn off the USB port during sleep. If that happens, your phone battery will be drained by the PC instead of charging.
Newer laptops now carry USB ports that will not turn off during sleep or off for the purpose of charging.

Perhaps, or it is not your fault and simply a bad cable.

Won't charge from computer?

Anyone else notice that it won't charge from a computer? (well monitor) With my Aria i ran a USB cable from my monitor at work to the phone. the monitor wasn't connected (USB) to the computer, and it would just work as a charger. Doesn't seem to work with the atrix. anyone else able to confirm?
more info. does in fact charge when connected to a computer. but due to security reasons the company does not want phones connected to the companies. That is why i was using the monitor. Going to have to look into why it doesn't work this way for this phone. or just buy a longer cable and use the wall plug.
Mines actually not charging when connected to my laptop, wall is fine. The phone recognizes that it has a usb connected, but it doesn't charge and battery state still reads as discharging.
Also wondering if this is an issue for anyone else
Mine charged extremely slow from my PC and my laptop, the wall charger does it much faster.
USB ports on a computer don't usually provide enough voltage to charge a phone as fast as they normally do when plugged into the wall. My motherboard actually has a piece of software that supposedly enables phones to charge faster when connected to a USB port, but i have yet to try such a feature.
I've had my Atrix plugged into my computer for roughly 3 hours now, and so far it's gone from 30% to 60%.
I wouldn't be the least bit concerned if it was charging slowly, it was actually lower after unplugging than it was when I plugged in, and no charge symbols appeared. But if I plugged it in the computer saw it and soon as I unplugged the message popped up saying low battery please reconnect charger, and when reconnected it went away.
But there was no charge symbol and under battery status it said discharging.
Now I just unplugged from wall charger (worked fine first time) and plugged back into laptop, its charging fine so hopefully it was a one time thing.
Ah, so thata what it is; I have had mine on here for a while now and im still at 60.
Rooted/ROM Captivate
Rooted Atrix
When i first plugged mine into my desktop computer, it wouldn't charge at all. I then installed that motosoftware that came with the phone and after it finished the phone started to charge, but very very slowly.
Every computer ive tried works fine.
But when i plug it into a wall charger(not one that came with atrix) it starts freaking out lol. "unplug to save energy!!" flash on & off 3/second...atrix charger works fine tho...lame
You need the driver off the motorola site to charge the phone from your computer.
Yea, computers work, monitors don't. I'm guessing that the USB hubs in monitors don't have enough juice, even though they did for my Aria.

[Q] USB charging issue

When i charge my phone from a wall charger it charges perfectly all the way up to 100%. However if i charge it using my pc from its usb port using a usb cable it usually charges upto only 14% and then gets stuck at it, charging is also very slow compared to charging with the wall charger and i do also sometimes get random reboots when charging it with my pc using usb. So how do i fix this issue as i do not currently own a wall charger of my own and have to borrow it from my cousin
Problem solved
so i figured out what the problem was and now it's charging all the way upto a 100%.
instead of plugging the usb cable using a usb extension or on my casing's USB port i plugged it directly into the USB 2.0 port at the back of my mother board and it started charging normally again . no random reboots etc. So please close the thread

[Verizon] Phone now only charges when plugged into a Samsung wall charger

Well this is odd, happened overnight too suddenly.
The phone now only takes a change when it's plugged into a Samsung wall charger. I have no idea what could have happened, I woke up like I normally do, phone happened to be off. Plugged it into my normal cable which is in a hardwired USB wall outlet. Wouldn't start charging, the lightning bolt didn't go away. Tried different cables, nothing. Tried different USB wall outlets, nothing. Finally dug out a white Samsung white USB wall charger, plugged it into the same wall outlet the USB charger is built into, used the same cable that was plugged into the wall, and it started fast charging. I have never even seen fast charging before this. Tried different cables with the wall charger, they all work.
Things that no longer work also include plugging the cables into my USB ports on my laptop. The same white usb cable that worked with the Samsung wall charger wont charge on the laptop. Actually, now that I am trying it the laptop / phone doesnt even detect a data connection anymore. The lightning bolt on the phone shows that its plugged into some kind of source but I am watching the battery drain.
So what the heck could be going on? Samsung charger works perfectly and the phone charges back up but anything other than the Samsung charger does nothing
