Went to sleep last night with my Atrix plugged in as I normally have had all my phones, was playing with it right before I went to sleep and everything worked just fine, woke up this morning and the phone will not power on!
First tried to power it on unplugged and the green light flashed for 2 seconds, and nothing happened. Okay, weird, but I'll go with it. Plugged it in, and the green light stays on now until I press the power button! Once pressed, it flashes off, flashes on for 2 seconds and stays off. Nice. I thought the green light meant it was fully charged - when I woke up this morning, it had no green light on, but it was plugged in just fine all night - grabbed my Jawbone ERA and plugged it in to the charger I had the Atrix connected to and it started charging right away, so I know it works....
Pulled the battery, tried plugging it in and power it on without the battery. Nothing. Tried putting in the battery and plugging it in again to "jump start it" as I had done yesterday when I first got it - apparently you can't just charge the thing when connected to a laptop if the phone is off, it will power on even if you power it off again! Nothing.
What the hell happened in it's sleep? I KNOW rooting it didn't cause sleep death.... This thing doesn't have a custom ROM or any undervoltage adjustments, so why the hell is it acting up??? Damnit, right when I got EVERYTHING set up the way I wanted it too.... can't bring it in to the store and give it up with all my personal stuff on there now, I need this thing to power on to wipe it first!!! I'm leaving it connected to the laptop with the green light on for a while and will see what happens in an hour or so....
EDIT - just searched for and tried to hard reset the phone from this thread, the phone still won't even power on to get to the recovery screen!!!
UPDATE - see below and use the SUPPLIED Moto AC charger or at least one with over 5.0V - NOT a PC and NOT a USB hub!
use the charger that came with the phone. My old HTC ones won't charge the phone for some reason. I bet your battery is just dead.
Did you use the provided charger? I tried plugging my Atrix in to the charger I used for my N1, and found that it did not provide enough current. With the old charger, after the phone died, I had similar symptoms where the green light would flash but phone would not come on. Plugged it in with the Moto provided charger, and 5 minutes later all was good...
I had the same problem. Thought I was gonna have to take it back to the store. I don't know what the problem was but I took the battery out for 5 minutes. Then I plugged it into the wall charger(wouldn't work with PC). I didn't turn it on for 30 min, just left it on the charger. Then I hit the volume rocker and it showed the battery charging symbol which it didn't do before. And then I was able to power it on
Same thing here. I purposely drained my battery on the first use. Plugged the usb cable into the PC and nothing. Same blinking green light with no response. I also thought I'd have to return the phone. Then for S & Gs I plugged it into the wall charger and it came to life. Once I got the battery charged a little bit I plugged it into the PC and it started to charge again. Don't know why, but it worked.
Have been running around the house trying to find valid outlets, and that does indeed appear to be the problem. I found it out the hard way though, should have kept an eye on the thread - used a power outlet instead of a PC USB connection and the screen fired right up! Yes, the phone showed the battery with 0% in it, but at least the screen finally came on!
How I have my phone set up normally is connected to my charging valet on my dresser, connected with a 15 foot USB cable that plugs directly into my desktop. Since the extension is good for just one USB connection, I have that connected to a USB hub and then a MicroUSB cable connects my phone from there. The Captivate, and all the other phones I've ever used, not to mention my Zune and Jawbone ERA, all eat that up and have no issues since the USB hub is powered not by the computer (seven USB cables is just too many for a single PC connection) but by the power outlet in the charging valet. I wonder if the hub is distributing the power requirement for each device and the Atrix needs more than others.
I also figured out that the Moto charger has a 5.1V output on it, as does my Jawbone AC charger. Now I need to start making sure that my each one of my chargers in the cars I own has that same type amount of juice too! You go up 29% in battery capacity and so do the requirements to charge it, huh?
Thanks for all the help, marking this SOLVED....
I used the charger in my bedroom that I've used for the Captivate and others before it and it didn't provide enough juice to charge the Atrix. It quickly switched between charging and not charging. I still had 40% battery showing when I woke up though which was nice. It had been off of charge since 10am yesterday.
Plugged it into an HTC charger and it's fine. The one that didn't work is not a modular charger so the power cord is hard wired to the plug.
Alright, a quick update.... Got the phone charged to 100% while it was off and plugged into the AC outlet with the Moto charger. Put my SIM card back in it - couldn't be without a phone all day! - and fired up the Atrix. Went to Battery Info to see what the status is and while plugged into my USB hub, it says
Battery Status: Discharging
Power plug: USB
....
Battery Voltage: 4124 mV (or 4.124V)

What the hell? Then I went right after that and plugged it into the Moto AC charger, it says:

Why are POWERED USB hubs and PCs not strong enough to charge the phone? I tried ALL my outlets in my vehicles just now and they ALL show full battery status and plugged into AC! Who screwed this up????

Did you download the PC Charging Drivers that Motorola requires you to have in order to charge via PC and USB cable? If not, look here.

Wait, you have to have specific drivers on the PC so that the phone will allow a power cable (let's not even worry about it being a USB cable for a second) to charge the phone properly? I have the Motorola Media Link software installed, and that has a ton of drivers on it, that wasn't enough? MORE drivers are required to charge a cell phone? This is madness!
Sorry about the necromancy, but had this problem myself but it is NOT due to a lack of voltage. Thought I'd actually solve this, the problem is CURRENT.
USB2 ports will only ever supply 500ma which simply isn't enough to charge the atrix when it's dead. USB2 powered hubs won't supply any more than this either to meet the USB2 spec. The fact that the AC adapter works is because they tend to have a higher output current in the region of 1-2 amps (you may notice the phone, or any other device for that matter, charges faster with AC adapters for this reason).
On a similar note, cheap car chargers only output 500ma. I know with my desire I can have it plugged in and it charges, but if I use GPS it actually draws more current than it can charge at resulting in the battery draining (albeit, slowly).
So, make sure you have a higher current AC/Car charger, or alternatively, plug it into a USB3 port to charge as USB3 spec allows 900ma (some mobos output up to 1A) which is enough to charge the Atrix.

Not sure about this..... It's been about a year since I got all my USB3.0 gear, and I was super excited about it because I thought that my phone would charge ridiculously fast because of the added output, but I remember reading that 3.0 uses extra pins and those pins account for the added voltage and bandwidth of the cable - we don't have those extra pins when you step down from 3.0 to 2.0, so we lose the ability to charge devices faster as a result. I don't know if I actually proved that theory, but after I read up enough on it, I thought I just didn't have to with that knowledge..... again, correct me if I'm wrong, I've got a lot of 3.0 gear here!!!

There are indeed extra pins in the USB3 standard but these are to transmit data only. The original USB2 data pins are only there for legacy support and USB3 transmissions use the extra lines. There's still only the 1 VBUS pin which supplies the +5V power. There's also no harm in offering higher current on the connection as a device will only ever draw as much current as it needs until it tops out the supplier, not the other way round
EDIT: Another solution could be to use a splitter cable (common with 2.5" drives)so you can draw from 2 ports, but with a micro connector. I've never actually seen one with USB micro but a quick look on ebay says they do exist

This is the exact same issue that I am facing now. Did you ever manage to find a solution for this problem?
atrix 4g not coming on
Is there any real fix to this issue i have search high and low and all i am seeing people talking about the battery id dead ... i have two battery that is fully charger and the phone still not coming up.
Hi all, sorry that im posting after two years ago but i am facing exactly the same problem, but i plugged it in my USB port, wich i think its a usb2, and i got the screen on but the cellphone did not say charging instead of that was connect your charger, and it was lower than 3% then it turned off. What can it be a solution??
None of the avobe solutions worked?
Which rom/kernel are you using?
I too have this same issue. My Atrix won't come on. I have 2 of the same phone. I tried the charger and cable from both phones. Neither work. When I first plug it it, the green light comes on for a few seconds then it goes out. I even opened the phone and removed the battery. Used a voltage tested and found my battery has 3.7 volts. Thats almost 100% charge. So it not a problem of power. I plugged the phone to my computer and same green light for a few seconds then gone. Won't do anything. No battery display or anything. I even did the simulated battery removal procedure. Didn't work. Is there anything else I can try? Can't get to recovery mode without display unless someone has a fix for that?
So I am eagerly awaiting S-Off and flashing new ROMS/kernels/radios and I started to think about how slow my Rezound seems to charge. I know that the Thunderbolt had some kernels that included fast charge capability. Just think of the extra juice we can get in a short amount of time with FastCharge, UnderVolt/UnderClock, and more precise power management.
Does anyone know if this is in the works for the Rezound?
My Rezound charges up pretty fast, especially compared to my Droid Charge.

if your charging on USB it wont be giving the phone full power, to remedy this get a spare cable and disconnect the data so only the power is working
not sure if it works on the computer, but in my car it definitely worked
yeah definitely do a search for USB AC Charging. You can take those car chargers and wall chargers that don't give you the full 1A and do a quick solder job on them to make them work. I just did it with two of mine and it works great. Battery info now says Charging (AC) instead of charging (USB) and they both pull north of +700mA while charging instead of ~+300mA when on regular USB.
Yeah they called it the charge cause its always on the charger

i did that. opened one up and clipped the green & white data cables. the phone still says "charging usb" though and doesn't seem to charge much faster...
Yea, I have tried every possible method of grounding out the data pins. I currently have my phone connected to a computer power supply I converted to a desktop supply with 4 USB charging ports. It can supply up to 13A if the device needs it. The data pins are all shorted and the housings grounded. The phone still says USB Charging....It does seem to pull more current and does seem to be charging faster.
I know that there is some hardware limit on the charging current, but with an SBC kernel (please someone make one...) I think that this bug will be fixed. I am going to try the Trickle Charge technique from previous HTC phones to get a full 100% charge. I will let you all know how it goes.
Or ...
Fast charging is built in ...
... turn off your phone when charging, and use a 1A charger.
DONE.

So I tested this idea that Fast Charging is "built-in", I used a usb cable that I split connected through an Ammeter to test how much current the phone was drawing from the charger in the one and off state. From my tests I found that my phone, no matter what the state does not draw more than 400mA from the supply. My charger is capable of supplying up to 13A to the four usb ports I installed. I also tested this with the HTC stock charger rated at 1A. This had the same results. I think that there is a hardware/software limit built in.
Just to be clear and justify its place in Dev, this thread is asking if there are any developers out there who are working on an SBC (Superior Battery Charging) Kernel for the Rezound. I fully understand the workings of power supplies (I'm an Electrical Engineer) and am just trying to see if anyone is working on this.
And it still belongs in General. That doesn't justify it. If YOU developed a Kernel, or were posting it, then it could be posted here. Questions, suggestions, complaints, ideas, etc belong in General.
Not sure accurate battery monitor widgets are, but mine has shown upwards of 850mah on charging and over 700 on draw (never saw that on my thunderbolt).
It does seem to slow down as it gets close to full (over 90%), then I never get more than 200mah charge.
Does anybody else have an issue with their X2 when it's plugged in to either the wall or computer of the screen not responding like normal thus rendering the phone completely useless while charging? It doesn't happen every time, but probably 35% of the time which is still more than it should. And it's not just my phone either, my wife's X2 does it as well and all 3 of the X2's I've had have done it on both stock and eclipse.
Just wondering if anyone else has ran into this issue.
Tapped from my Eclipsed X2
I believe the charger is to blame not comlatible. Not every charger is setup with same pins or wattage... if ur mis-matching equipment.

I have noticed this. With mine the keyboard becomes sluggish and the lockscreen is hard to unlock. I have eclipse now and it hasn't done that yet.

I've used my old Crackberry charger along with my usb cord for the cpu, car and wall chargers. Havent had this problem. Strange......
Today it hasn't happened on the same cable at work.
Mine doesn't seem to take issue with any specific charger or cable except for one which is the one that was sent with my wife's phone from verizon, screws both of them up, and it's a moto charger with the same voltage/amperage as the other moto ones, but it has a 9 ft cable.
Tapped from my Eclipsed X2
Interesting it has happened on vz provided chargers. Do theyhave the Moto M on them, or sonething else?
Mine specifically is 5.1V~850mA. Has a USB cable. Has a port we can plug a cable into.
I'd be curious what everyone else has. I wouldn't think it's the cable itself but working in technology, I've seen stranger things.

It could be one of two things, either:
1. you're using a usb cable with a broken data pin.
2. you're using a charger that doesn't output enough current.
the problem lies in a lack of available current in a certain charging state, a "fast charge" if you will. you get either not a high enough sustained supply voltage, or "dirty" power (essentially a little AC in your DC) and that really screws with the capacative touchscreen.
with a bad cable, the phone thinks it's plugged into a charger and not a usb port so it will try to draw up to 850ma from a port that can only feed 500ma if you're lucky.
with a bad charger, or one incapable of supplying the required current, you get "DC ripple" where your voltage fluctuates up to half a volt or more, 60 times every second. generally your phone will get very warm under this condition as well.
so it could be a cable, a charger or a combination of both.
some car chargers are notorious for making dirty power... so are some cars...

Oddly enough I have zero problems with the car chargers, the phones work fine when plugged into them.
Yeah the newest cable is one that is USB and 9 ft long but not moto one that verizon sent with my wife's phone. The moto one that came with mine an the two moto ones I got from Amazon I don't have any issue with but the cables are so stinking short they are a pita to use anyway (2' cables).
I've also noticed that the USB ports on different computers charge at different rates as well. My work computer will barely charge the phone and sometimes can't even maintain the battery level if I'm using it. My laptop at home charges it pretty good but you can't use the phone because you get the screen issue again.
Tapped from my Eclipsed X2
Yeah, I have had this same issue for quite some time and after reading this forum tonight I tried a new charger and BAM, problem fixed! I had thought it was my phone, but it was definitely the charger. The one I was using was the Verizon 9ft charger they send out with replacement phones. Model: B141000. Black with green on the back. Gave my wife my charger that came with the DX2 to take to work and use because I liked this big long cord. So for months now whenever I tried to use the phone while it was charging it lagged so bad I would have to continuously unplug it and plug it back in when I was finished. Needless to say, having a text conversation when battery was almost dead was really annoying...
So when I read this post tonight I went up and grabbed my old Samsung charger from my old Samsung Fascinate and sure enough it worked just fine... No lag what so ever. So I am guessing it is an issue with the DX2 and the generic Verizon charger they send with replacement phones not being compatible...
Furthermore just as a test I just tried the actual 9ft USB cord with the Samsung plug you plug into the outlet and its still working fine... So I assume its the Verizon plug part not putting put enough voltage or something. Pretty happy that I can seemingly still use my 9ft cord! So if you have a spare plug I would say give it a try!
here's a weird one..
when using the wall charger that came w/ my phone, instead of charging the battery its actually draining it, the battery icon says its charging/plugged w/ power but after leaving it plugged in eventually it died out, but if i plug it in my pc it charges w/ no problem..
pls help me or enlighten me as to whats happening...
thanks in advance.
Strange. It should be the other way around. USB 2.0 sockets push 500mah which isnt enough to charge the S while the wall chargers provided are 800/850. Perhaps a dud socket? Try another and if not your charger is fúcked.
yeah, i think its my effin charger, i plugged it in a diff outlet still same, i tried using it to charge my iphone its not working as well. thanks for the help.

For me it discharges faster than it charges. It may charge off yours but typically it'll be very slow or not at all. Some ports push more AFAIK, but the standard is 500max.
I also noticed that, if I have WiFi on, the phone actually discharges when connected to the PC (when used anyway).
I don't know how much current is provided though, never measured it.
If charging through USB is fine then it might be that the charger is shorting the battery + and - through some resistance.
Try another charger and see if it helps , and replace the faulty one. You don't want to break your battery.
On my laptop usb port it will charge just fine. Slower than the normal charger but it does work.
On my desktop pc otoh it drains more than it charges. So there probably is a difference in output on the usb ports.

If you were using "front ports" these are often underpowered compared to ones mounted on the mobo(back of case, or all laptop ones).
I connect my phone via my front ports and it charged just fine actually...
I am behind the computer quite a bit and my phone keeps its battery and charges when attached, even when I'm installing a bunch of apps (I tend to browse the market via my browser and pick up apps as i go) I still don't discharge...
It could be a voltage issue with your ports, but with my frontal ports I notice no problems...but anyways, this isn't about the ports, this is about the OP's charger.
To me, it seems like your charger is faulty.
Hi,
I wrote about a similar issue I was having with the phone discharging when connected to USB.
http://forum.xda-developers.com/showthread.php?t=1573336
From what I could tell in my tests that I did the issue is when the phone is connected to the PC and THEN the PC goes into Standby mode. Even on a powered USB hub the phone charging mechanism does not reset correctly and continue charging but begins discharging.
I would have loved if someone else could have tried to reproduce what I wrote in that thread but no one responded. For me the only solution is to charge directly with the AC power and not through the USB as my PC goes in and out of standby regularly.
Phone charghed with USB will drain batery faster then phone charged with wall charghed.
It was thread in xperia arc about that, the test bring that conlcution.
So i recomend to charge with wall for better batery efecienty.

Good afternoon/evening/morning/whatever,
I was just wondering if anyone has used "fast charge" mode? Or uses it regularly? From my understanding it will charge the battery at rates upto 650 mah while hooked up to USB. (Normally phone only charges at that rate when on wall plug I believe) I know on a normal USB 2.0 port this will result in over-drawing the port and that's bad. However from what I know USB 3.0 support current capabilities upto 900 mah, so it shouldn't be a problem then.
I'm just curious because i had read the other day that someone said it would do damage to the phone, so is there something I'm missing? From my understanding the only damage that would be done, would be to the computer that's being overdrawn. So long as I'm hooked up to a USB 3.0 port shouldn't it be fine?
Thanks!
I did that numerous times with no problem. It should not damage the phone under any case, though it can damage your USB port by overloading it with higher than designed current. Also though as far as I know USB ports on modern motherboards has protection against overloading.
Yeah it can destroy USB ports, but definitely shouldn't harm your phone. I have my USB current that high because my phone thinks it's connected to a USB, when its actually on an A/C charger. Therefore making my phone charge slow....

I had mine on fast charge overnight and forgot to switch it back to normal. Later in the day I plugged my phone in my car and left it for about an hour. When I went to take the phone off the charger it was like holding a lava rock. I'm talking HOT. I turned the phone off and took the battery out for about 15 min and it cooled off. The point of my long boring story is that even for as hot as it got, I don't think it caused any damage to the phone
