[Q] GSM Galaxy Nexus charges while off, but sometimes doesn't charge when on

I just started to have charging issues a few days ago. I have not changed my charging equipment and don't think it's hardware. I have tried a variety of wall chargers and cables - some Samsung and some not.
Here are a few facts (as far as I can tell, from testing).
USB connection (I almost never charge this way, but it's helpful in the car.)
- Charges fine connect to USB/Wall charger when phone is power down (completely off).
- Leave it connected to wall charger and boot and then it no is no longer charging (after it was charging fine while off).
- I did get it to charge after booting it a number of times. I don't know what triggered it.
- I made sure to hold the device steady while booting to make sure I didn't change the cable contacts
Desktop Dock (This is how I usually charge - in the dock while I sleep)
- Charges fine in dock when phone is power down (completely off).
- Sometimes starts charging and engages Daydream when put in the desktop dock
- If it doesn't charge in the dock, a reboot usual starts it charging/Daydream again
This sure sounds like a software problem to me, since it charges fine in both scenarios when it is powered off. Any ideas about any software or device settings that may block charging after boot? Any other ideas on what is happening?
Device particulars:
Galaxy Nexus i9250 purchased from Google Play US
Android 4.2.2
Rooted using Nexus Root Toolkit (from Wugfresh)

Thanks. I have cleaned the port out and moved the pins toward the screen. it doesn't seem to have helped.

[SOLVED] SM-P605 (kitkat) battery charging problem

It is solved! Some 3rd-party usb chargers have same issue.
Samsung standard charger works very well.
I have a Galaxy Note 10.1 2014 edition (Hongkong, TGY).
Yesterday I updated my device to 4.4.2 (P605ZSUCNE3_P605OZSCNE3_TGY) with Odin.
Upgrading was OK, everything works fine except a battery charging problem.
When device connects to a usb charger, the battery stops charging after 1-2 minutes although not 100%.
I tried something but nothing helps.
- Changing charger/cable to another
- Factory reset (Recovery mode)
- Flashing P605XXUCNE2_P605OXACNE2_NEE (Nordic) Firmware
- Power off mode charging -> It works. This is the only way to make device 100% that I found.

I've got the same issue following the 4.4.2 update, all my third party charges that worked fine before the update no longer work. Battery management software show the device getting the same mA of current to the battery but the device is not charging (it says that it is!).
Original charger does work but is not a valid solution for me, why are the non-oem chargers not working all of a sudden and how do I get them to work again?

I'm having the same problem, trying to fix with some charger mods (shorting data pins of USB) or fast charge kernel. The kernel hack did not work yet, but shorting the d+ and d+ pins of usb cable on device end works. (although I could achive max 1.5mah)

According to this
http://www.androidpolice.com/2014/0...t-on-the-note-3-but-there-is-a-root-solution/
Samsung denies any intentional blocking and a connection between KitKat and third party accessories.
I tried my third party chargers and they too didn't work. Charging stopped when the screen turned off. However, my Motorola and HTC chargers do work. Maybe the third party tings have inconsisten voltage output or something like that.

I had the new Tab s 10.5 and some of my usb chargers would not work. I found a deal way to good to pass up so I returned the Tab s and THOUGHT I was getting a Note 10.1 2014 wifi. Yet lol I didnt I got a 605 which is AWESOME ..I just always wanted the SnapDragon chip. It was a tad over $400 32gb NEW.
Anyway so I turn it on set it up and it was downloading 4.4 already I wanted to stay with 4.3 after reading around here. Yet so far it works flawless. All my usb chargers work. I can be doing ANYTHING and it keeps charging. Like I said the Tab s I could ONLY use Samsungs.

In my case Android 4.4 for P605 is way better than 4.3. Great battery live, great performance, no or very small lags. But I had initial release of 4.3 ROM which was never updated.

I have a third party charger and it goes well. It is Chinese no marks.

If it is just shorting the data pins, then it will charge. But you will be limited to 1500mah.

I think it needs an Apple compatible charger. Only the Apple standard supports charging over Usb 2 at 2A, for the Ipad.
The Anker 5 port 8A charger is fantastic.

No, I did that mistake and bought a dual port 4a charger. Samsung somehow detects Apple charger and stops charging when screen turns off. I had to make an adapter for shorting data pins, like this, I can at least charge with 1.5a

while i was on vacation my p605 starts having the same problem. It is just loading while the screen is on. After getting black/off it takes a few more seconds till charging stops. This problem is accompanied by the symptom that the tablet won't be recognized by the pc anymore. It is just loading ('til the screen gets black). i have no idea what to do. i am not sure, if the different voltage on vacation could be a reason. based on the fact that i can't get it back to stock, i guess i can not get it repaired by warranty (or is there any way to get it stock? unfortunately mobile odin is not supported). i would be glad about some good hints and thank you in advance

Your cable or charger might have a problem or you may be using a different charger than original one.

Hi everyone,
I've found a bit different issue - my P605 (LTE) does not want to be charged when plugged into USB port (so, no charger is being used).
I tried both using laptop and stationary PC
//ok, nevermind. I've just found somewhere else, that it has been always like that (not noticed that before)

Exact same problem here - charging stops as soon as the screen lock kicks in, even with the original Samsung charger. Brought the tablet back to the tmobile store and had them connect to another Samsung charger - still happens.
Has anyone found a fix for this short of shorting the harger pins?

I don't follow my own advice, and never had this problem. But charge with the original cable where the two GND pins are connected. In most cables one of them is open.
My old Garmin Street Pilot with mini usb used the second GND pin to determine whether to remain operational and charge, or go into pc connectivity mode and do nothing else.

I have the same problem . After upgrading to Kit kat just a few days ago it would stop charging moments after the screen turns off. No matter what cable or charger

This happens to me only when I'm not using original 5.3v charger and original cable. Check your cable and charger. (although I think it works with 5v Samsung charger of my note 3 as well)

My last charger had 4.9v with no load, and certainly lower with a 2A load. No Problems. But if a charger is badly stabilized, it may drop too much, and the Note is very demanding, with twice the current of a typical phone.
I had a DIY adapter to charge my old Nokia stuff via USB. The Nokia chargers have a 5v spec, but one provided 6v, another 7v. And USB voltage seemed too low, there was sort of sporadic charge, with the connection dropping after a short time. But all connections were fine, must have been a voltage thang.
So i still have to keep a Nokia charger ready, only to charge my Nokia BT headset.

Galaxy Note 10.1 2014 Edition Charging Fail
Has anyone discovered a fix for this:
When I plug in my tablet...Samsung Galaxy Note 2014 Edition...Using any plug (I have tried factory charger, and multiple alternatives including Ipad Charging adapters) when the screen is on the charging occurs, but When the screen closes about 2 seconds later the screen turns back on the way it does when charge is complete, only its still at same battery level as before! I have tried closing all apps and still the same, Used Task Manager to close all apps and clear the RAM and still nothing, Gone into app manager and closed running processes and still the same results! I am operating KitKat (OS since purchase) and the only actual way to charge it is to leave a plug in all day with the screen On, or shut off the Tablet!
Is there a fix for this or what?
Its bad enough that I cant find a good bluetooth keyboard that is compatible with this tablet! Im on the verge of trading it in and going Apple! Someone please help...Keep me from turning to Apple!
Is there a fix for this even if it requires manually adjusting chargers or the tablet itself (the internal components)?
thank you all for your help!

[Q] Nexus 7 won’t charge

Hi I bought my Nexus 7 2013 used in February. It came with a 3rd party charger and usb cable. It’s worked fine since I got it and it use to charge fine. I would use different usb cables and they would all work. Within the past 2 weeks or so it has become increasingly hard to charge it. Also this started happening on the stock 4.4.4 rom with root enabled. Today I installed a custom chroma 5.1.1 rom just to see if anything changed but it’s the same result it doesn't charge. The chroma rom says it has the Franco Kernel. Not really sure what that means but the stock rom's kernal wasn't changed.
I've left it off and connected charging to the AC for hours and would turn it on and it would have not raised at all in battery charge percentage. When it’s on and I can better see the percentage in this battery app I have installed I noticed if I jiggle the cable at all it will disconnect and connect again. So it might not be making good contact. It does this with every usb cable I have tried on it. However when I don’t move it and have it charging in sleep mode it does see it as connected and it says charging in the battery monitor widget app when I wake it, but it doesn't charge stays at the same percentage or lowers.
There is sometimes where I get lucky and it starts charging but it’s becoming increasingly tougher to get that to happen. I haven’t had any luck since last night messing around with it with different cables. I've even tried charging it on my PC but it’s the same result. It says charging but it doesn't charge. However if I do connect it to the PC I can view the files on the Nexus 7 fine as long as I don’t move the Nexus 7 much. I've also tried the AC adapter on my phone to see if it works and it works fine and charges. I've tried a kindle fire 9w charger on the Nexus 7 and that doesn't charge either.
Any idea what’s the problem? If I buy the official AC charger do you think it would work? Am I better off buying a Qi wifi charger? I rather not waste money on the AC charger if there is a good possibility of it not working.

Hi,
I seem to have the same problem recently. I am running on 20150519 CM12.1 nightly right now but this problem started to occur about 2 weeks ago i.e. with an older nightly version running...
It really feels like the USB connector is broken. I have to move it the same way headphones jack has to be moved when it is broken. Have you tried more different chargers? I did but no solution.... Now I got it luckily charged to 90% and I am making a quick backup.
Do you have still warranty? I technically do but would need to get back to stock and lock the bootloader back.
I found threads on how to get back to stock via USB connection but is it possible to lock the bootloader without being able to connect USB to computer?

No unfortunately I have no warranty since its a used item. I tried the 3rd party cheap charger, amazon kindle fire charger and my phone charger on it they all don't charge. I think you can replace the USB board on it but that would require opening it up and doing the repairs yourself. I think I will just get a Qi charger and see if that works. I kinda don't want to spend money on that just to find out its my battery that doesn't work. I am not sure what the problem is since I can connect the nexus 7 to my PC and it will see it and its files fine. So I know the USB port works at least a little bit.

It's a sub-board (usb-sim-touch module) issue. I would reccommend using a wireless charger as a quick fix since the wireless charger module is located on the motherboard itself so you should be good.
I may have a few sub-boards for the 2013 lying around but i'm not sure if they're 100% okay - as in calibrated, tested and fully functional. Also, i'd need to know if yours has LTE or not.

I have a Nexus 7 2013 32gb wifi edition. Thanks for the info. I put in an order for one of those wireless chargers.

perhaps you did that already, but from experience i must say that in 9 out of 10 cases it's the cable and 8 out of 10 cables are mediocre as compared to how it could be. no why i say that ist because i tested something between 50 and 60 cables during the last 2 years because i had similar issues and bought a special ampere and voltmeter with with the correct usb ports to measure the flow, same device, same power source, thus as empiric as possible result most cables charged between 0.9 and 1.1 A while about 10% were half of that and only few charged at 1.5A while 3 charged at between 1.9 and 2.1A. understand me right, same device, same charger, sam place all same condition, in car, on motorbike, on wall plugs. only significant difference were the cables. so check those first before taking more costly path which then only remain workarounds.
BTW amongst the bad ones were many that came out of the box with the devices and from different oems but many samsung original cables.
what i did i painted the ends of each cable with red for bad, yellow for ok, green for good and the outstanding ones already had a color, it were the stock cables from the oneplus one which had the best charging rate. good luck

USB C just charging on one end when turned on

Hi everyone,
Something really strange happened to me last week (or at least I started noticing it last week)
First, when my HTC10 was turned on, it didn't recognize the charger at all, I tried different chargers and cables and the result was the same. If I turned off the phone it worked perfectly. I wiped the cache and tried again with the same result. I booted in safe mode and got the same result.
I hard reset my phone and loaded all my apps again and now the USB C just works when I plug it in a certain way when turned on(one of the two possible ways, impossible for me to know which of them). When turned off it works perfectly.
Does anyone has experienced this? I think maybe it's related with one app, since when turned off it works with no problem.
UPDATE:
I just hard reset my phone again and loaded NO apps but still the same behavior: when turned off USB C can charge the phone no matter which way I plug it, but when turned on it doesn't.

Power phone up with it plugged in. Does it charge then? I get that problem often. I've narrowed my problem down to when I start my car with phone connected on charge (using car charger). Won't charge after that till I restart phone. I'm assuming it gets over or under voltage and safety circuit kicks in until restart. In your case it might be a charger or cable problem (or combination of both).

I think the problem was the cable I was using, after a while it started doing some crazy stuff like saying that I was not using a powerful enough charger. After I changed it everything is working like a charm

I'm experiencing similar problems, but this happened to me after my phone totally discharged, i repost my experience:
Hi guys! i'm occuring in a big problem, i was wondering if anyone of you had this experience with this or others phones, two days ago my htc 10 was totally without battery and died, so i put it on charge, but nothing happens, no led on, if i try to power on, no signs of life, unable to make it boot, even after hours of charge, i noticed that the phone anche the charger were cold, instead of hot like it should.... but after hours, even without led indicator on, i trying to recover it, with surprise, it was hot, i tryed to power on, no signs, i tryed combination of power button and volume buttons and it booted into dowload mode, and after a millisecond it re-died, and booted normally with 65% battery. BTW from that point the phone is unable to charge if i plug the cable into it, nothing happens, but if i put the cable, when is off, it charges even after boot, i tryed to recalibrate battery but nothing happens....
today, one day later, it seems the things are getting better, i'am able to charge it without having to put the phone off, but i always got the message that the charge is slow.

Clean the connector on the phone, make sure it's nice and shiny.
Give the cables a buff up, reboot your phone.
Allow it to boot, connect the official HTC charger in the wall.
Connect the official htc USB c cable into the charger and unlock your phone.
Connect the cable to your phone.
If that doesn't work, try a different wall socket.
Are you on stock? Have you altered any voltages? Any quick charge mods?

If you can reverse the modifications you've done to it I'd be tempted to say take it back to htc and get it sorted. Shouldn't be like that. Personally that's what I'd do.

Phone won't charge with original charger

Hi, I've been having this problem with my pixel 2 xl that won't recognize any usb-c to usb-c cables. It will only recognize a usb-c to usb-a cable but will keep restarting the moment I plug it in. I've tried many things like restarting, trying to charge while it is turned off, booting into safe mode, and even updating to the Android Q beta (hoped they would've fixed it then), but nothing seems to work. I'm confident that it's a software issue since there would be random glitches where the original charger would actually work, but every other time it doesn't.

Also, I'm actually considering switching to a custom software. I'm thinking since the software is the issue, maybe it might help to fix it. Has anyone ever experienced this issue as well?

That's the very first thing I did. It's not an issue with the port since it works perfectly with a Usb-c to usb-a cable. Just it doesn't fast charge and it constantly reboots with it.

I'm having the exact same prob. I've cleaned my port, tried it in safe mode, and did several resets (soft and hard). I spoke with Google and they offered an exchange since it's under warranty but my glass is cracked so that voids it out until I get it fixed. They said it would restart afterwards? I'm stuck trying to figure out if I want to fix it and do a swap, try different firmware or just get a different phone all together??

I'm having the same issue. Started this week.

Your testing methodology is flawed. The restart loop occurs at the P2XL splash screen, which means control of the device is still in the hands of the bootloader. Since the bootloader is outside of Android, Android cannot be the culprit. As a result, neither safe mode nor Android Q would resolve the problem.
Have you attempted moving your data off the device's internal storage and reinstalling a stock ROM using the included flash-all bat with the -w flag present? While we have determined that Android itself isn't the culprit, Google's ROM images also install bootloaders and basebands, either of which could be the source of your issue.
Once a stock ROM from Google is installed, test your device. If the restart loop occurs, then your issue is NOT software, but hardware. So then you'll have to test the hardware. Find a charger from a different device and, using a USB-A to USB-C cable attempt to charge the phone. If the restart loop does not occur with this combination, then you know the P2XL charger is faulty. Otherwise, the charging circuit in the P2XL has malfunctioned and thus service will be required.

Are you all on Android q beta or is this happening to stock non rooted too? I'm on q

FYI, I had this same problem a few months ago and it turned out this is a relatively common hardware issue on Pixel 2 XL.
It usually starts by occasional failures to charge (original charger), then it becomes more frequent, then you can't charge and find that the only option is an usb-c/usb-A cable (less power involved). Finally every time you plug a cable it restarts the phone.
Did all possible known troubleshooting, cleaned the port, engaged Google remote support, ...
At the end, the conclusion is that sometimes the port gets loose and related wiring becomes unstable.
To fix it, I had to send the phone for a port replacement.
Working fine since then.

I had a similar issue after the July update. If I plugged the original charger and cable in the phone turned off. The only way I could charge it was to use a USB-A to USB-C cable with a slow charger (non QC) and the phone had to be off. Did RMA with Google after doing safe boot, reset and other things. They noted the security update as reason so maybe that's the problem?

I have the problem since pie and even though Google accepted to RMA the device at first they then declined to do it because I didn't have the the purchase id of the device.

I'm doing the rma while I can. The more I read about it, the more I think it's due to the faulty fast charging. It might be damaging the charging port and causing these problems. What I find strange is that some other users also started having these problems a week ago like I did.

Port overheating may be causing it to become loose. That's my impression due to what happened to me.

Mine started working again. Weird

I just did RMA because of this... The new (refurbished) device is working now....
I edited the post because when I first tested my charger wasn't plugged in and I though that the new device had the same issue... ....:silly:
In any case do RMA..... Before this happened my pixel only charged with one side of the cable connector (any cable) then it magically got fixed and after two weeks it didn't charge with originals chargers (only when it was turned off)... Definitely was something hardware related...
