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.

Charging issue

Hello everyone. I just want to start off saying that this is NOT a question about USB charging. I know about the trickle charge/lack of voltage stipulations. This is about the factory A/C adapter and USB cord I got with my transformer.
About 80% of the time I plug in my tablet to the A/C adapter, literally nothing happens. The screen doesn't turn on while in sleep mode like normal, the battery in the bottom corner doesn't change to a little lightning bolt, and most disturbingly, my tablet will not charge. The weirdest part is that it connects to the computer through USB no problem. I can move files and such, but no charging. Any ideas?

the charger construction is marginal at best and may need to be wiggled to get a good connection. also the usb connector an be plugged into the charger incorrectly. remember the usb connectot on the supplied cord does not comply s
with the usb spec. Also chev
ch the country ac side adapter ther are also unreliable

My cable went screwy and now it only trickle charges, regardless of what it's plugged into. I've got an RMA for it, but since I have to send them the cable to get a replacement, I'll have a paperweight for a few days at least.
Are you sure yours isn't trickle charging? There wouldn't be a lightning bolt, but I does charge.....very slowly.

Unplug the AC adapter from the wall for about 20 minutes. Plug it back in. Plug in TF.
Charging now?

unplugging it for a while seems to work better than anything. I'm pretty sure there isn't any trickling going on.

You can also try using the charger for your phone if the plug is a USB type. There have been a lot of problems with these charges documented in other threads.

Unplugging it definitely isn't a solution for me. When it first started happening I could do that and after a little while it would start working properly again, but now, it has charged at normal rates in about 3 weeks. I'm going to send it in with the RMA, but I have no idea what the turn-around time is. I'm going to be without any way to charge for that time, which pisses me off just a little bit.

Phone doesnt reliably charge when connected to PC

Anyone else notice the phone randomly doesnt charge when plugging it into the computer?
The battery will say charging, the lock screen will say charging, but the battery screen will say not charging and the graph will show a green charging line but draining battery. Replugging the phone in fixes it. I havent had an issue with the wall charger.
Theres nothing wrong with the USB ports, it charged my other phone fine and it charges this phone when it works.

my N4 charges fast when I plug it to my laptop. I connect it to my USB 3.0 port..

PCs aren't designed to charge phones. It may work for a dumbphone with a 500 mAh battery, but it doesn't have the amperage to charge a smartphone efficiently. The charging adapter that comes with the phone is 1200 mA (milliamps), a computer USB port only provides 500 mA (on USB 2.0). On USB 3.0, it provides 900 mA, so it will charge faster, but not nearly as fast still as the 1.2 amp travel adapter.
On top of this, the phone is constantly using battery power while on, so it is very likely that when the screen is on and you are using the phone plugged into the computer, the phone is drawing power faster than the computer is charging it.

That is not what Im talking about. It says charging everywhere except the battery screen where it says not charging, that is obviously a bug. A computer can power a phone fine anyways, they are made to be powered by a USB port.

I had this problem today. The battery was dying fast (Average for this one) and I had popped it into my stereos USB, The battery didn't show the charging sign.
WTF? So I switched to the "Cigarette lighter port" and with a different cable plugged that in. No go. Held in the power button to simulate a battery pull, Still didnt work.
Turned it off, Went back to work and three hours later getting ready to drive home i plugged it in. The phone was getting warm, But the battery charging sign never popped up. I turned it on and the left side (By the sim card) was getting ultra-hot but betterbatterystats said the battery was only feeling at around 101degrees (Normal for this small sun). A minute later it was highly uncomfortable to hold (Just near the sim card area), I thought the battery was going to catch on fire like those youtube videos.
I power cycled once again, the battery charging sign popped up and I breathed a huge sigh of relief. Seconds later the phone ****ing flipped its wig, It kept making the charger plugged in sound and vibrate every half second. I about had a stroke, Thinking it's going critical. ONE MORE POWER CYCLE, Everything is normal.
My earlier experience seemed similar to yours OP, Let me know if your phone melts your hand off and goes all bi-polar like mine did.

I'm having the same problem. It has nothing to do with a computer not being powerful enough to charge it, especially when they aren't even being used such as overnight. It has charged every other smartphone that I've used. It will say that it is charging on the lockscreen and on the settings pulldown but it will just constantly drain battery. I will put it on the charger before bed and wake up 8 hours later and it says it is at 86% with a steady decline in battery. This only happens when connected to my iMac and not when plugged into a wall outlet.

I wouldn't think USB 3.0 improves the charging speed at all, since the protocol still uses USB 2.0

I just remove all the cables and replace them. It seems to solve it.
Same with the AC adapter. I noticed sometime it would say charging USB when I switched. I just unplug everything and plug it back in and it goes back to normal.
/shrug

I havent noticed it getting warm, it just doesnt charge even though it knows its plugged in and is supposed to be charging. It works after replugging it in.
It also seems to charge abnormally slowly.
I wonder if the issue with the phone not working right with Nokia chargers (constantly disconnects and reconnects) is related to this. It may not have anything to do with the Qi standard because the phone just doesnt charge right period.

[Q] Overnight: Charging to 100%, then discharging while still connected?

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

Charging problems

I just got my Note 3 working thanks to this group. When I first got it, it was without a battery and was locked by PIN. I was able to wipe it to factory conditions, but now it will not charge. It charged right away when I first got a replacement (OEM) battery, but then, I did the system factory reset, and now it will not charge. I am using a USB 3.0 cable and connecting this to my Apple charger I got with my iPhone 6 as I don't have a specific charger that might have come with the Note 3...just a generic USB 3.0 cable and the iPhone 6 charger that the USB cable plugs into. Any thoughts for me to try?

Try plugging the cable into a computer. It might not charge fast but it will let u know if it will charge or not. Iphone charger might not be compatible so battery will not charge.

I have tried using the computer and that is part of my confusion...the phone will indicate it is charging...but it doesn't. I get the same indication whether I am using the computer with USB 3.0 cable, or using various wall charger pods with the same cable. It will show the charging symbol (lightning bolt) or, if turned off, but plugged in, it will show the upflowing green drops rising toward the battery. So, it seems to indicate it is charging, but the charge percentage never increases...only drops.

It's not unheard of for a brand new battery to be defective. If you know someone else with a Note 3...try swapping batteries with then and see if the problem moves with the battery.
There is nothing in a factory refresh that would effect the charging circuit.
