Strange USB charging issue - XPERIA X10 Q&A, Help & Troubleshooting

So I went out and bought a 2nd USB cable to leave at work to charge my phone. But for some reason the USB cable I bought doesn't charge the phone...instead it drains the battery..??? The light is on and the icon shows it is charging when I have the USB cable connected and I can even mount the SDcard with it. But the battery percentage slowly goes down. The USB cable that came with the phone works fine without any issues.
Is there something special about the stock USB cable? Do I have to buy a certain type of cable to make charging work?

I bought another two cables, even used a Motorola USB cable but never noticed that... it never happened to me.
My guess is:
Fact:
- charging through the pc USB port is so slow, to get full charge you need 6-8 hours compared to 1.5-2 hours through the wall..
Scenario:
You are using your phone or running heavy application while charging it so it drains more battery than charging ..
Just a guess.

[Q] dropped phone. slow charging!

the other day my phone feel of the couch while pluggd into the pc. it stopped chargibg and woukd not connext to pc.
i lost the original cable so ive been using a mini to micro usb adapter for an old cable i had for my g1 which hss worked perfectly.
thought i had broke the sockey on thr phone. had a tmobile shop check it with there cable. it was fine. so boyght a microusb cable.
everything seemed fine. charge light. usb drive worked internet tether. but then the phone ran out of battety while usb tethering. it always stays at 100% before.
with the battery low it woukf rrstart every minute whole plugged into original chargrr.
its charging but very slowly. 15% in 2 hours. checked battery pins. seems fine. i dkd manage to get 37% charge in 30 monutes once irh the phone off.
the phone doesnt even get warm while plugged in. it used to get pretty warm when cuargibg.
tried hard reset. trief reflashig rom. it knows wall charger is in. says charging orange charge light.. but it charges sooo slow...
im stuck. is this a repair jobk
Just got home and tried the new cable in my home PC. ive already lost 1% battery in the space of a few miutes usb tethering....
make sure you have the "don't charge the phone while connected via usb" unchecked. Other than that, sounds like a hardware problem.
i cant find that setting, only do not charge when the phone is on., which is off. Ive just noticed something else. the brightness setting for AC power effects the brigthness when connected to usb. I dont think it knows the difference between ac and usb anymore.

when you plug it into the wall, do you get the menu for: Activesync, Disk Drive, Internet Sharing? If so, then this is true. Really sounds like a hardware issue. I would take it back in and see if they can replace the port.
nope, when i plug it into the wall, no menu. it does seem to know the difference between usb and power. as using the option "when phone is on, do not charge when the pohone is connected to pc" has no effect with the wall charger.
I tried a different wall charger. I have a travel charger which is only rated at 500ma instead of 1amp and it charges the same. I was able to get 100% overnight. woke up after 8 hours to see the green light on, it stays at 100% with the wall charger as long as you leave it alone.
back into the computer, tethering and im loosing battery as if it wasnt connected.
Looks like ill have to dig out my insurance as its not a warranty repair (and also the water damage stickers are red, due to it being dropped in the toilete 3 months ago)
hmmm interesting. phone has been in charger overnight and was at 100% when i got up, pluigged into pc for usb tethering, despite battery dropping the green light is still on.
Ive done some searches on usb micro cables and came across people having problems with some data cables with charging, as some cables cannot cope with the large current required, but they mentioned that there phone would say this and i have seen that on my phone before with my front usb ports on my computer.
Im gonna order a microusb adabter as i have 2 high qualiity usb-mini usb cables from a G1 (which was usbed with an adapter with no problems) and 1 from a tmobile mda varia, same cable.
This has now been solved. After closer examination of the USB mini to micro adapter, it apeared that the 2 outside pins (which are for charging) had been flattened. Looking at the adapter, you could only see the 3 middle pins, but with a torch you could see that the oiutside pins were compelty flat. from droping the phone its oviously twisted the connector resultinin in flatting those pins.
I went back to tesco and bought the same USB kit which comes with a mini USB cable and several converters to fit different phones.
AFter hooking up the cable and micro usb adapter to my PC, my phone was within minutes showing increase in battery charge. After a few hours with usb tethering enabled and watching videos online im up 2-%.
The cable i bought for £7.99 which is micro usb though doesnt mention any HTC phones (mostly nokia) will connect perfectly for data transfer and the phone appears to say its charging. It looses power suggesting insuficient charge current. Maybe its the rom im using disables thsi warning as i have seen this before when i connected my phone to the front usb ports, but it works fine with the back.
So, it seems i have not damaged anything apart from the usb adapter i was using.
All is well, and im charging at a fast rate with USB while tethering.
Please close this trhead as it is resolved.
Final update. After several days i have been usb tethering and charging absolutly fine. Using 1amp charger charges fast!
Even from a dead battery can plug into usb and have the phone bootup.

[SOLVED] Atrix will not power on, green light flashes, plugged in and.... nothing!

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?

[Q] Not charging? :S

Hmmm, this is a weird one guys.
I can charge my X10 only if it is plugged in to the USB port via the computer. However, when it is plugged directly into the power socket, it does not charge. Now, I've tried two different chargers, and both work when charging another device (my iPod Touch).
I don't understand. The cord can't be broken, since it works when charging from my computer? Yet, the charger (the thing that plugs into the wall) can't be broken either, since another charger didn't work and also both have the ability to charge my iPod.
What's up? :S
Thanks in advance.
NOTE: Even when charging while off works on the computer, just not when it's plugged in (and I am not using a custom kernel either). I doubt the ROM matters (since it still has the above problem while charging when off), but even so, I'm using v061 of Wolfbreak's 6.1.3 ROM.
Bump bump, bump it up!
Do you use the original SE in-wall charger? If not, thats the problem, if yes I recomend to test with a different wall charger (eg. from another device)
May be the cable it faulty? Because the PC charging uses a less amount of Volts (to my knowledge) and the charging while connected to PC is very slow. Did you try with any other Official cable?
It could possibly be your cable as mine broke a few weeks back (Same Problem), I just replaced the cable now its fine
Guys :-/
Went out and bought a new cable, and still not charging from the power Only from the slower laptop USB port :'(
I think it may be the X10 itself..
I am still suffering from this problem And sometimes when it's connected to the PC and displays 'charging', it instead discharges

Yep your usb port is broken, mine did exactly the same thing. You will have to send it to fonebiz in rockdale, nsw. I just got my phone back, took 6 weeks to repair!

Rockdale? 6 weeks?! Not going that far. :-/ I can live with just charging from the PC at the moment.
Thanks though Sad news indeed
Is is still under warranty? It will eventually stop charging from the PC too. I was waiting for parts to arrive so maybe they have them in stock now. That was 6 weeks from melbourne and back.
Going through the same thing in the US. I was told repair would be 5-7 days, but I'm sure I'm looking longer. If it comes back within the time frame they gave me I will be pleasantly surprised. I hope you're still under warranty and do your self the favor and send it in or soon you will have a very expensive paper weight. Good Luck!
I went through the exaxt same thing. It stopped charging from the wall but could only charge from computer but eventually stopped charging altogether.
Did you try taking out the battery and plugging in with the original se microusb cabe to the wall. After 5 min. put the battery in. First time didnt work for me but then i took out the battery again and put it back in immediately and then it turned on.
try getting a usb-to-wall charger, and plugging your computer usb cable into wall.

Out of curiosity, how long before each of your X10's stopped charging altogether? :S
Because, for me, it's been longer than two months and throughout that time I've managed to keep charging it via the computer.
Thanks.

I've 3 usb-to- chargers here:
From a MP20 phone, generic charger that can't charge my phone and also can't charge most of other devices, output power and voltage are low.
From an old Ipaq(not ipad) it does charge my x10 for some reason takes longer than the original, it says on it 1000mA and 5V, I don't remember the real amp and voltage on it.
And the original one, always charge really fast(2 hours for a full 0 to 100% when the phone is ON)
Conclusion, buy and original charger if you not using one, which seems to be the case.
OR, update your baseband if possible, as battery issues are normally related to baseband are normally the cause of this errors.
To make sure you can always try to do a SEUS repair.

Sorry to say this, but your are wrong man.
My charger says 5.0V which is exact the same voltage as any USB ports(exception for some internal USB ports used commonly for bluetooth and other low consumption devices that use 3.0 to 3.3V).
The difference is mainly on the amount of power amp it can supply, the original usb cable + wall charger provides 700mA, while in the PC USB 2.0 ports provide 500mA, 1.0 USB provide 100mA and 1.1 I don't remember now, generic usb wall chargers say sometimes they provide 500mA but they mostly provide 30l0mA and sometimes they do not provide on 5.0V they oscillate between 4.6 to 5.2V a good usb port have to provide 4.95V to 5.1V any difference from this may even burn a phone if higher and not charge or reduce a battery life if too lower.
Everytime a battery is not charged up the end of 100% they battery life gets a bit reduce as next time even if you leave it to charge up to 100% it won't really be at 100%, this can only be seen by measuring the battery voltage after the charge, fully charge it must reach up to 4.7V
on the battery or something like this.

If the cable is too thin(like 1.0 usb cables they can't handle 500mA if connected to an already extended usb port it may not get recognized and also not even charge.
Laptops usb ports may not allow 500mA it different for every laptop, some work, some doesn't and others your have to set that on bios.

Always when connected to the PC it should say charging, if it did say discharging at some point then there was something wrong.
But charging on the pc is very slow and not good.

[Q] Please Help w/ charging..

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.

Charging problems, SGS3 micro usb cable different pinout?

Hi everybody!
I'm having some problems when charging my device. I've noticed that when I use the stock charger with the stock micro USB data cable, the phone stops charging and it just charges the battery in 1% to 5% after I plugged it on the wall, and the charging led remains on. So I've left the phone plugged into the charger for 2 hours and nothing happens, the device remains cool and the charger remains cool either.
I tested the following scenaries and the results are pretty weird:
a) I tried using the stock SGS3's charger with my Nokia CA-101 data cable, and the phone charges successfully in about 2.5 hours from 0-100%.
b) I used the stock SGS3's charger and the stock data cable, and charged my old Xperia X10 mini pro and successfully charged 0-100% in about 1 hour.
c) I tried charging my SGS3 with it's stock data cable from USB port and It seems to charge very slowly: 20% per hour.
I don't like using different accesories to charge my phone, because I read somewhere that Samsung uses diferent usb pin arrangement because of the Device ID pin.
So my questions are:
What is happening with the phone/battery/charger/usb cable? They seem working well separately but not together.
Does the samsung micro usb data cable uses different pin arrangement than standad micro usb data cable? or Can I keep using my Nokia CA-101 micro usb data cable?
Any ideas?
Thanks in advance.

Hi everybody!
I'm having some problems when charging my device. I've noticed that when I use the stock charger with the stock micro USB data cable, the phone stops charging and it just charges the battery in 1% to 5% after I plugged it on the wall, and the charging led remains on. So I've left the phone plugged into the charger for 2 hours and nothing happens, the device remains cool and the charger remains cool either.

Hi.
I have the Samsung Galaxy S3 it is a remarkably simple phone to disassemble and I'm thankful for that since...
I also had 6 different chargers and cables that would not charge the phone reliably, I took it to Sprint and of course they plugged it in and it charged ok when left alone not moved in any way. Well the charging for me was very intermittent and some cables not at all. It was as if the plug was inserted and removed and inserted over and over again, typical problem if the solder of some connection on the PCB is broken or high resistance for some reason.
I removed the PCB from the phone and examined it to find a micro USB mounted to the PCB with 6 + 5 additional conductors, the 6 that were in the middle of the connector I believe connect directly to the conductors of the USB cable. The other 5, 2 on one side and 3 on the other of the main 6 were broken solder joints on 2 of them. I have a really fine tip solder iron and a microscope which helps but is not totally necessary to re-wet the solder on each pin of the connector. Now my phone works like brand new!!!
I have at least 33 years experience with soldering, so this operation may not be for everyone.
Good luck,
Dude I wish I had the confidence to attempt something like that, well done you

Have you ever done simple mathematic & calcs based on the current output?
You have 2100mAh battery in SGS3, right? And you have STOCK charger. Output = 1A=1000mA => full charge (assuming 100% charging efficacy) would be 2.1hrs. Therefore, 2.5 hrs result from not 100% charging efficacy - simple.
Now, you have USB port in your laptop/computer. From USB 2.0 spec, its output is rated at 500mA => full charge would be more than 4hours.
The difference is result of not 100% efficacy of charging, but this, I assume, you can calculate by yourself (to give you a direction: how much data is spent from a phone to power the screen and to supplot media connection with computer, while charging via USB?)
Sorry that I had to give you some basic calcs from primary school, but... this is what you asked for.
