ive had it for a month and a half and now its doing this, plug in the charger to the tablet and nothing. ive tried with different outlets aswell ive checked my power adapter to see if its one of the effected ones but mine was a pre assembled one. ive also restarted the tablet with no luck. time to call asus?
Do you have another device that charges by usb, that you could plug in to see if it sees anything for power? Not sure on the usb pinout for our chargers, but if someone knows, you could use a voltmeter to probe it and see if it has any output.
k got it charging now, hooked it up to my pc with the usb cord to see if the cord or the socket is shot, still connected to my pc....but it reinstalled device drivers as if i never used it on my pc. i turned usb debugging on then off, then i unplugged it and put the cable back into the power adapter and its charging
this is concerning, seems like a usb driver issue that effects the port not sure if i should call asus and do something about it
Sorry to bring this up but I started noticing this today too. I've had mine for about a month and everything's been fine. I noticed that the battery was in the 30s so I plugged it in via the a/c adapter and neither my battery widget nor the system battery icon change to the "charging state". I shut the device off to see if it would charge quicker and left it off for what must have been an hour and the battery has only increased by about 7%. I'm timing it now to see how long it takes.
This happened to me this morning. I couldn't get the tablet or the dock to charge. The dock was at 3% and the tablet at around 75%. Neither would charge either singly or together. I tried using a normal 5v USB charger for a few minutes, but without success. Then I fiddled with the charger and uncoupled the 3 pin UK adaptor. It then started charging. I'm not sure if it was coincidence or not, but at the moment it's working.
B50K tablet and B50K dock.
I have a B50 also running the newest firmware via Revolver 1.1.1, I just booted up my TF after an hour of it being off and connected to the A/C outlet to see how much it had charged. It increased 2% in the past 70 minutes. Something's Fishy here.
did u guys try method of hookin to your pc, then turn on usb debugging.
i havnt had any issues recharging since this thread was made
I connected it to the computer a few times and USB Debugging was already on, I just turned it off and I'll try and connect it again but I'm currently backing up stuff with CWM.
Edit: I just cycled USB Debugging a few times while it was connected to my PC. XP (virtualized through Arch Linux) recognized it each time, but still no change in the charging status. I'm going to unroot and go back to the stock 3.1 to see if it's a software or hardware problem.
Edit: seems to be a hardware problem considering I reflashed it back to stock (unrooted) and it's still doing it. Awesome.
Same problem here. All of a sudden I didn't see any status from the dock battery (dual battery widget). Tablet charges just fine, but the dock won't charge. even left it connected to charger overnight but the dock led just keeps blinking orange (/red). I'm afraid the dock will have to go RMA.
Just got an email back from Asus and they told me to fill out an RMA. It'd be nice if I got one out of the B70 batch as a return
edit: sadly, that didn't fix it. I re-rooted, let the battery drain down until it turned off and wouldn't turn back on, then let it charge for 2 hours. I turned it back on and the battery was at 5%

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.
I am trying to figure out why my DroidX will not charge fully all of the sudden. I plugged it in yesterday to a wall charger for about 2 hours when the battery was at 50%, can back after 2hrs, and it was still at 50% even though it showed the charging icon the whole time. I rebooted it, and plggeed it into my computer's USB port, and set the USB option to "Charge only". Came back this morning, after it sat there for 6 hours and same thing - it is just maintaining the current battery level, but not charging it higher.
I have only owned it for a week, and the only change between now and when it was charging properly was that I installed a wireless tethering app, however, that runs on demand, and it has not been open or running. WiFi and GPS are also completely turned off.
Anyone else experienced this? I assume unless I keep it plugged in 24/7 now, it will eventually die all the way down!!
p.s. - I also tried letting it charge while it was completely powered off, but same thing. Shows that it is charging but just maintains current level.

this is not normal ,while in the wall charger it should charge all the way and the same on usb but just slower ,if this problem persist i would bring it to VZW and get a knew batt or phone or both since you have only had it a week
It may not be the phone or the battery. It's probably a faulty DC adapter which is not delivering the proper amperage. I just had this problem with my Slingbox. It would light up but the lights looked dim and I couldn't connect to it. A new adapter fixed it.
(Edit) I just reread your post and noticed you are charging it on your PC's USB port. Try the wall charger or another PC. Some PCs don't put out enough juice to charge.

This is somewhat true. The phone should charge with less power regardless of the source. You notice this most on say a USB hard drive and this is why you have y cables sometimes on the drives that take more power. Does the computer you happen to be charging it on happen to be a Laptop?
FYI - I charge from a desktop PC that has a 1000W corsair powersupply and hig end motherboard.
With that asie though, I was able to get the charging back - works fine after I did a hard reset. Most everything was backed up via Google, so all I had to do was rearrange my icons on home screen and change a few android settings.
I still have all the same apps, so I do not know what caused it. Whatever, it is fine now, but if it happens again I will take it in - I do not want to have to hard reset every few weeks. (I have the $6 a month full protection plan, even if I lose it, it gets replaced)
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.
Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.
is this the only time it happened?
It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.
Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers
did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.
This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...
Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)
it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...
Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.
Are you using stock kernel?

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...
come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.
Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246
So this issue happened out of no where after my phone died to zero last night. I tried charging it back up but all I could get out of it was the grey charging battery but it would only stay on for 1-2 seconds shut down and reboot. Let it charging for an hour and got to about 1-2% and it would die as soon as it booted up. Factory restored to OA6 and still see the same issue. This is also the odd thing... I was able to connect it to my computer and use Oden to do the restore! After lots of troubleshooting, trying 4 chargers, I realized wireless charging still works fine. Charged it up 100% over night and wireless charging is still working fine and phone is working fine. Still cannot get USB to be recognized while on either by computer or from USB charger. With a full battery, phone off, and USB plugged in phone still flashes the grey battery icon and reboots constantly.
Only thing I can think of is I had it in my pocket after spin class for a little and moisture might have gotten in the port?
Any ideas what happened here?
Update: I ended up just buying the Nexus 6P since I'm about due for a new phone anyways.
Well just figured I would pass this along. Was bored before and looked at diagrams to fix the USB board and saw this little port in the back you can access really easy. Decided to open that up and press the connection down a little tighter (the USB board is separate from the main board). USB didn't work before doing this, then pressed it tighter plugged USB in again and it worked.
