Now my phone won't charge

Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?

Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.

Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.

Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)

Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...

im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).

Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.

I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.

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] AC charging grinds phone to halt and prevents charging

I'm running:
GEN2
Rooted
ClockworkMod
Swedish Spring Android 2.2 with Gingerbread theme and circle battery
Suddenly after a few weeks of everything working fine, AC charging stopped working. USB charging still works perfectly, and when I plug the phone in it says it is AC charging, but the charge level barely changes - it can be plugged in for 12 hours and not gain or lose any charge. Also, sometimes but not always, the phone becomes very very slow, and sometimes the screen won't unlock - I have to unplug it, unlock, then plug it in again.
I've tried different chargers and cables and combinations thereof, I've tried turning USB charging off or on in Extra Settings, I've tried debug mode on USB or not, hardware acceleration on or off, I've tried charging with the phone off or on, screen on or off, I've tried charging it for 48 hours, the charge level never moves.
This is the closest thread I can find on the issue but it is a mix of problems, and they never find a reliable diagnosis or solution:
http://android.modaco.com/topic/336...rs-stopped-working-but-usb-charging-works-ok/
I don't care if it charges slowly, I'm thinking of trying to mod a USB cable to force it into USB charging mode. Anyone know how?
I far prefer this to re-installing because whenever I connect my phone to my laptop it immediately bluescreens, (despite a fresh Win7 reinstall), and I am lost on my gf's Mac.
These posts describe how to do the opposite (force AC mode) on HTCs:

Thanks enormously for any tips

Since I lost my charger and had to use a generic micro-USB charger, I have the same problem. USB charge works fine.
May be a problem with the USB cable, have you tried using another one?
(I'm on Ginger Stir Fry, but I don't think it is ROM dependent. )

Thanks for the thoughts. I've tried different cables and chargers and combinations thereof to no avail, hence suspecting something software and looking to mod a cable to force USB mode.
Please anyone know what PINs indicate laptop USB rather than AC USB?
How does my phone know to go into the (disfunctional) AC mode?
Thanks

I think D+ and D- pins (2 and 3) are connected. You would have to mod the charger. Or just use generic USB charger, like those from dealextreme...

[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

[Q] Nexus 7 only charges when connected to a PC, not a USB wall outlet

Seems a bit odd but my Nexus 7 (1st Gen) will not charge when connected to a USB wall outlet. But it has no issues charging when connected to a desktop/laptop.
The following I have tried:
- I have rebooted, shutdown, booted into the boot loader and shutdown/rebooted from it into the OS
- I have tried several USB wall power adapter range in amps output from 0.7 to 2.0.
----Also tried 4 different USB cables with the USB wall power adapter.
-Enabled/disabled developer mode along with USB debugging mode
-Tried charging the unit when it is OFF and ON, only charges when connected to a USB port on a desktop/laptop
-Removed the back cover to see if the USB port could be loose, looks and feels securely in place
Not sure if it could be a software issue, unit is running 4.3 build number JWR66Y. I am hoping to avoid resetting the unit but if I have to I will.
Thoughts anyone?

Is your device rooted? If yes, then try to change the ROM (make a nandroid first).

maybe this shud work for u , it worked for me

I would say if your rooted and cutomed and all that try a different kernel before a whole new rom. Kangaroo kernel first page of dev page is good.

Mine gets stuck sometimes. I installed battery monitor widget to see the actual current flow when charging. Even though it shows ac connected the graph can remain flat with no charge. Replugging the cord a few times gets it going. A charge only USB cord might help, but I've gotten the best amperage with the included cable so far.
