Hello folks,
I have a Nexus S running Stock 4.0.4 and it shows charging on the lockscreen along with the charging battery icon even after hours of being disconnected from the wall charger.
If i check under the about phone tab in settings and check under phone status, it shows discharging.
I tried wiping the battery stats and reverted to official stock ROM again after wiping everything completely from adb.
I tried moving to different versions of Android OS, namely 2.3 and 4.1.1, and it shows the same thing.
Sometimes, when i power off and power on the phone, this goes off. But when i connect th phone to the laptop, the mount SD card immediately comes up, but the phones starts charging only after a couple of seconds. And then it still shows as charging even after removing.
It looks to he hardware issue...any ideas???
clean the micro usb port with a tooth brush that should help some i have a ns that does this, it works and charges fine
I had that happen quite a bit a few months back. I haven't had it happen since switching to CM9 though. Pretty sure its just a visual bug. Reboot makes it go away.
Let me try both the things...let me clean it and comletely wipe the phone and install CM9 just to check if it works better..
One more thing....if i remove the battery and connect it after a couple of minutes. Without me powering it on, the screen wakes up and shows the charging animation even if i haven't connected to any charger.
I think you got a defective USB port..mines was like that too before...the only way is to send it back to samsung

Unless its completely different from what happened to me... its NOT defective! Mine has COMPLETELY stopped doing this behavior since being on CM9...
you shouldnt need to send it in, the phone still charges and discharges the same it maybe is some reporting bug or error or something, more than a few nexus s has had this and still work fine

No man.....havent found a solution yet...the phone charges and discharges properly...it just that it doesnt show it properly..
also i think it has something to do with my micro USB port...as when i start the transfer of files from my laptop to phone, it stops for a sec and starts again..
Hello All...i fixed the issue....i guess i was using different microUSB chargers all the time...
i noticed that the metal slab inside the microUSB slot was very close to the bottom...so i took a needle and pushed it properly towards the top...now the metal slab is exactly in the middle...and the charging crazy stopped immediately...
make sure u do it when the phone is off and the battery removed...
i figured where's the harm in doing this as Note 2 is releasing shortly
jokes apart..please bend it slowly towards the top and the issue is resolved.
Hi mate, try another kernel.

I did that...i went to stock gingerbread...then stock ICS and then to stock JB....ofcourse wiping everything through adb along the way....tried CM9 RC2 too..
the thing is even when the phone is switched off...the screen wakes up immediately and shows the charging animation...when its unplugged...
Battery charging animation even after disconnecting the charger (SOLVED)

Thanks...This tricked work for me too on my S2 this morning....I think I did not had the charger removed properly and the animation went crazy... I thought kernel related problem (I had tried TWRP version of Sammy Apolo 4.14 on freshly flashed ROM) and flashed compatible Philz kernel but did not work...I also did a dirty flash of my ROM but to no success....I switched off the phone but even when switched off, the charging animation came and went and when I tried to reboot the phone, I couldn't...So I even tried removing battery for about 5 minutes and placed it back, it finally booted but with animation still going bang bang.... and I then I went crazy...I have read about the toothbrush cleaning trick but before doing so I looked at the usb port but was not much sure what to do.. I thought it had bent a bit but after I saw your post, I immediately took out a needle and bent it slowly in upward direction and that was done ...However, I forgot to take off my battery before doing so but guys, its always safe to take it out to avoid any problems..... :good:
So the moral, please take care while using your usb port....
Tried the following methods=
Cold boot
Switching from PC USB to Asus charger
Switching from other manufacturer's charger to Asus
Freeze the charger(???)
Adaptor charge the tablet in good order, but it doesn't seem to be charging the doc.
The dock is always blinking rapid amber led when plugged in and the adaptor just get really hot.
Guys, any advise? Warranty expired, it gonna hurt my wallet to send in for repair ;(

If you let the dock drain 100% it sometimes encounters problems. If you open up the dock you will see a little switch. Flip it back and forth and it should start charging again

Got the same problem as the OP - Dock not charging and even the dock option is greyed out within the Settings - Interface - Launcher option.
My question is - Is there any software command that would simulate the flipping of the switch using ADB etc? Would not want to open the dock as yet..
It works properly when I attach it to the tablet, only problem is that it doesn't charge...Any pointers would be more than welcome!
Am on 4.1.2, CM10 2012 12 08 Unofficial
Thanks!
Try a cold boot, it fixes lots of these problems. Hold the power and vol down buttons till you see 2 icons on the screen, then release the 2 buttons and let it boot. Try it while docked and it should start charging again.

Yes, already tried that (it says cold booting linux and all..) , I tried it while docked and with the charger in the dock..but still the same orange blinking light..Dual Battery Widget also doesnt detect the dock..though I can type with the keyboard and all that stuff..
Guess you should open it up then, and try to switch trick as I doubt there's an ADB command for a hardware switch inside a "third party device" since it's not part of android but really an extension that probably requires drivers and/or kernel modules outside of stock android. If there is, it's probable it's not documented if it was added by Asus for Asus. While it's opened up inspect the battery for obvious signs of wear/damage. Dual battery widget didn't work for me on some ROMs (can't remember which exactly but only the tablet battery was detected) but recent CM10 should have a separate icon with a dock through the battery icon while docked.
You can try the dumpsys utility from ADB, which prints out battery info so you may find something, but you can't manipulate data at all:
adb shell dumpsys battery
Also, did you try wiping the battery stats in recovery? If you have that option...
And lastly, lots of people are suggesting the freezer trick. To me that would be last resort but it looks like it's working for some people it seems.

Thanks for your detailed analysis and useful suggestions - just reflashed the CM10 8th Dec UNofficial rom y'day only and then recovered all the apps etc..But your idea of wiping out the battery stats didn't cross my mind! Should be there under advance I guess within recovery..(Have touch based 5.9 or something)
I would let the charger plugged into the dock and then try again the cold boot trick to see if that resolves the issue..Else would see if I have the option of wiping battery stats within recovery..
I am currently on vacation and hence donot want to open up the Dock here, freezer trick while harmless but I fail to understand logically how that would help Nevertheless would try it out if the above doesnt work..
Would report on the updates tomorrow (after 12 hours or so.)
The freezer trick is an oldie but a goldie. I used to do it with old hard disks that had certain problems and it worked in some cases, but usually you had an hour or so to salvage the data then it would die for good...
The logic behind it is that cold contracts the parts while heat expands them. So if it's a bad solder or something alike, the cold can temporarily fix it. But as I said, it would be a last resort for me and I'd triple seal it in ziplock bags to make sure no humidity can get in or out.
Let us know how it works out!

I am actually inclined to open up the keyboard and flip the damn switch now!
Also I did try cold booting (as the tablet had charged to 98%) and also wiping out the battery stats, but no change in situation still.
Opened the keyboard, flipped the switch but still no change..Orange light just keeps on blinking approximately every second..
Am at a loss to understand what could be the problem - the dock and tablet were bought in Sep last year and the dock has hardly been used (probably not for more than 20-30 hours in the last 14 months or so..)
Anyway I havenot closed the keyboard completely, would flip the switch again after sometime and see if that changes the charging behaviour in any way!
Anyone who has had success with dock charging issue after flipping the switch?
Update on previous post - Suspecting that it could be a software issue as well, I flashed an old Megatron Rom (based on CM9), and tested the switch again.
Switch off - Only EeePad's battery is shown
Switch On but no charger - Dock's battery is shown (symbol of battery + Keyboard) BUT with a red exclamatory sign, along with the normal EeePad's battery
Switch On and with Charger - Dock's battery is shown (symbol of battery + Keyboard) with charging sign , along with the normal EeePad's battery
So definitely an improvement as compared to CM10!!
Wondering if I should search for a Stock (Rooted ?) Firmware and flash that..Or probably just a firmware for the dock (does that exist?)
I'm pretty sure there is firmware for the dock (I think you see it in the settings while docked) but I don't think it's available, nor does any rom actually change it they just "use" it. For sure the best thing to try would be stock now with dual battery to make sure it works properly. Easy flasher will get you back to stock, provides root and can install different recoveries for you (there's plenty of others but this one seems easiest and worked best for me).
I'm thinking you're right on both accounts: the switch did work and there's a software issue somehow causing this. I've seen stranger things with custom roms. Glad you're making progress!

Thanks a bunch Lethe6 !! I have downloaded the Easy Flasher (V 0.8.3 Stable) and am downloading the Stock Rom from ASUS WebSite (300MB)..Its a slow connection here, so I would be able to report back by tomorrow only..But I am optimistic that Stock Rom should resolve the issue with the charging!!
Thanks once again for providing the links, I would report back tomorrow on the progress!
UPDATE on prev post - Flashed the latest stock from ASUS Website ..It does show the Dock Battery BUT at 0%
And from what I read here, I seem to have run out of lack as apparently there is a design flaw wherein there is no way a dead battery can be revived!!
(I ran out of warranty in September but as I wasn't using the dock really at that time, I didn't bother to look into the issue at that time..)
That really sucks But it must be a particular model because mine has went to 0% numerous times and I've never had that issue before. Did you try the freezer trick? At this point if it's supposedly completely dead, might as well give it a shot. Also some people suggest plugging it into USB for 5-12 hours, the trickle charge may help getting it going again. If the tablet is not 100% charged the dock won't start to charge either, so try just with the dock then try with both. Also check this out, sometimes strange fixes are the best.
You can probably find a refurbished dock for under 100$ during the holidays online, if you really need it.
Out of curiosity which series dock do you have? Mine is a B70 purchased in UK last September..(Tablet is also having a S/N starting with B70 and SBK v2)..
I tried the other fix as well that you mentioned - that is using a different USB charger, to my surprise without the tablet attached, there was no light on the dock. but if I attached the tablet, then orange light was blinking much quicker! So seems like the dock is quite sensitive wrt the current supplied through the USB cable..(Guess all USB chargers have typically 5V output or something?)
On using the original ASUS USB Charger, light blinks slower (with or without the tablet attached)..Have left the charger plugged in again ..in the faint hope that some trickle charge is able to revive the dock's battery!
And no, haven't tried the freezer trick as yet
Would probably contact ASUS UK once I am back in UK..
My "mobile dock" version (you can see it in settings -> about tablet -> mobiledock) is EP101-0213 and my tablet is SBKv2 C30 purchased in Canada 6 months ago.
There's a nice article explaining voltages and amps in relation with phones (which applies to almost any mobile device), however from what I read, the Asus wall charger has a different pinout for USB and feeds the power differently. I'm sure you can find the exact specs here somewhere, I saw people showing how to make your own charger.
But assuming you're right and it's sensitive to the current (Bad design? Cheap parts?) then it's possible that simply replacing the wall charger would solve it. I bought a spare one to leave at work for 8$ on ebay and it works nicely so far!
Just out of curiosity.. did you/can you try to connect it to another power source? Like a different house? I once had a problem with a charger that there was too much noise on the electrical system and the charger couldn't keep a decent current output because of the variations, so the phone would say it was charging but it wasn't; tested later at several locations and it was working. I know it's a long shot but hey at this point...
Thanks! Would have a look at the link you provided..Meanwhile I also came across this link which kind of indicates that using a 12V 1A charger fixes the dead battery! Would probably order the relevant stuff from ebay and see how it pans out! Just crossing my fingers at this point really and have also left the charger plugged in to see if it does trickle some charger into the dock!
After flashing the latest stock rom (instead of CM9 or CM10), I also have same version for my dock ending in 213..
Finally apparently it seems that USB Debugging off/on also seems to affect the dock's battery as per the various other charging related threads on XDA..
Thanks for all your suggestions - you keep me motivated to try out various things and I am learning new things as well !
PS : Forgot to mention that I had already tried a different power outlet (i.e. in UK) and now another one in a totally diff country!
I believe I have a hard brick, but not sure about diagnosis or options. I put my phone on the charger last night, and it was dead this morning. I have been able to get it to boot twice only for it to shut off immediately due to lack of charge. I have plugged the phone into 3 different USB chargers and none of them appear to be charging my phone, however they all work on my Nexus 7. There is no LED on to indicate it is charging as it normally would. I cannot get into recovery or download mode. Any suggestions?
A little background about my specific situation:
I have had my S3 since launch, and have had no issues with it. I have had it rooted since the bootloader was overcome, and have run custom ROMS ever since. Most recently, I have been running CM 11 with the latest nightly being from early Feb. (not sure which date). I have CWM installed, and up til this point, my phone was working fine. I did get occasional random reboots since the latest nightly that I flashed, but the phone remained completely functional.
EDIT: It is not a brick problem, it is a charging issue. I can charge my phone in the car, but not through a wall charger or connected to a pc. When plugging into a pc, it does not register anything at all.

It's possible that your usb port is bad, but try to clean the inner contacts of the port first. You could try to plug into your PC instead of wall charger see if it works. In anycase if it worked with PC, but not wall charger or both, you need to replace the usb board which can be purchase for cheap on Ebay.

Do you know of someone who has an S3? Perhaps try swapping batteries with a charged one from a friend/associate, or test with a spare from a verizon store. At least then you can rule out a charging/USB charge port/battery issue vs something else

I don't know anyone. I am going to try and seek help at the verizon store, but they seem so useless whenever I go, and I think they will be more motivated to sell me a new phone.
Well I got my phone to work. I pulled the battery off and just cleaned out some of the dust that had collected. I assume it was just not getting a good connection. Thanks for the suggestions though

Turns out, it only worked on my car charger. The problem persists outside of my car. I cannot charge either through a wall outlet or on a USB cord connected to a PC. I have tried 2 instances of each all with their own cables. My car charger works fine though.
Anyone experience a similar problem? I am going to try and wipe and flash a new ROM, hoping that will fix it.
Hear me out. I now this has been brought up in various forums, and trust me I have searched them all. I just have not seen anyone speak of the exact scenarios I have experienced. At least not together.
So I have 2 Nexus 5's, a 16GB and a 32GB. My 16GB has no issues at all with the random shutdown\reboot running L up to 5.1. My 32GB however exhibited issues immediately after upgrading to the 5.0.1. During the initial update it barfed and went in to a boot loop, even in Fastboot. I eventually got it back up and running and rolled all the way back to 4.4.4 and then stepped up to each new version up to 5.0.1 then 5.1 once it was official. Still experiencing the shutdowns and reboots under certain circumstances.
I have noticed 3 things that appear to cause the issue:
1st Wi-Fi - With Wi-Fi On it happens repeatedly when entering or leaving a new wireless network. With Wi-Fi Off I can go days without issue.
2nd 3.5mm Audio Cables - Jump in my car, fire it up, plug in to my stereo and poof, it reboots. Possible its just cheap audio cables??
3rd Car Chargers - I have only seen it with car chargers, but if I have it plugged in during a drive it will randomly reboot or power off. If I have it plugged in with the car off, as soon as I turn it (the car) on my phone reboots\shuts off.
Appears to be some impedance change on specific types of load or something. I am no electrical engineer so I could be way off. One thing I have noticed that I know others have as well, is that when a reboot\shutdown happens the battery drains like crazy. But I have also noticed that if it is plugged in to a power source between two back to back episodes that it charges super fast while it is down. I'm talking 25-30% increase in a matter or 2-3 mins.
So with Wi-Fi off, and good headphones plugged in I can go all day listening to music and it works like a charm. Bluetooth does not seem to be an issue, as I have my Moto 360 paired all day too. Running with Wi-Fi off, not plugging in to my car for audio or power I have not had a reboot\shutdown for 3 straight days.
I have seen some say its software, some hardware. Some say factory wipe, clear cache, etc. Send it in and get a new one (this one is out of warranty). Or download official and start from scratch. I've done these, and still it persists. Tried other ROMs as well. Have not gone down the route of different Kernels. Given that Wi-Fi is on one board, power on another I would assume its not hardware. Then again since I have flashed, and reflashed between official and custom ROM's I would say it is. At a loss. Willing to try anything, I really like this phone.
This might be a cracy solution.
As I experienced the same random reboots on 5.1, I worked myself through the usual process: hardreset, reflashing the rom and so on. Even called google for RMA, which got green light as they couldnt find the issue either.
Turned out my new case pressed too hard on the on/off-button, shame on me. Figured it out in time fortunatelly.
If theres no solution for you , send it in directly to LG. They repair it and hopefully the price wont be too high. Good luck!

I use a CruzerLite case, does not cover the power button, and I have had the case on my 16GB as well, so I "believe" this would not be the issue. Then again I might as well try to run it outside the case for a while just to see what happens.
I might have to go down the LG route, really hoping not to though as I have heard the cost is pretty high. Would rather then just save the money for a new device.

My point exactly.
I just changed my battery and after I did that I saw rainbow colored vertical lines when booting up when I tried to change to the old battery the issue persisted, then I charged my phone because I thought maybe because its a new battery it needs that or something and then my phone actually booted up but I saw only a black screen (i knew it booted up because i seen the charging light powered on) it stays black even if i boot to recovery or bootloader, what to do?
Sounds like a hardware problem. Did you check for any loose or broken connections?
It's the ribbon cable for the screen, mic, usb port etc. that goes right over the battery OR the connector of that cable.
Try to replug, or heaten the connector on the mainboard while the cable is NOT plugged in with a heatgun (but ONLY the connector or something will break)
I fixed a mainboard with heaten the connector so it resoldered itself

I have the same issue, too. Problem occurs because of the flex cable which connects almost everything in the phone and it is sold approximately $5 or $6 at eBay or AliExpress. I ordered one in my country and replaced it. Problem solved but when the phone is fully charged, I try to use Instagram or Twitter etc. (which causes to run the phone at high frequences) and phone freezes, reboots itself. I do not know what to do for proper fix.

I've been using this phone since 2014 and from 4.4.4 KitKat to 6.0.1 Marshmallow (and almost all custom roms from 4.4 to 8.1.0). When this problem occured, firstly I tried another rom including the stock roms. Nevertheless, it was not about firmware. Also I tried old flex cable and for 2 weeks it worked again. By the way, screen flickering appeared again and now I replaced the new one and trying to manage this situation
