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

I have an untouched, unbranded Defy on 2.21 which works fine until I connect it to a usb lead for charging whereupon the touch screen stops responding and usually remains like this for about 30 seconds after I have unplugged the usb cable.
Until this morning when I had had it connected overnight to a cradle by the bed and could not turn the alarm off. I ended up pulling the battery, but at least I was awake by then, I suppose.
My question is: is this a common problem, and if so is there a cure?
And a supplementary one: would a custom ROM, CM7 or Miui, solve the problem?
Any help greatfully received!
my defy behaves exactly the oposite way. When connecting with USB cable I am able to ude the phone properly, everything works fine all applications' responsiveness are great. However, when charging the battery using the power cable, the phone starting hanging on every application. Everything starts getting slow and a simple touch takes 5 or 6 seconds to retrieve any action from the phone.
I dont know if this a common behavior for the defy neither if has any fix for that, i got used to it so i always charge my phone when it is off.
I have this issue too, but a little different. When I use a different charger than the original one, the screen is stuck, but I think, it is charging. When I use the standard charger, it works perfektly. I can't explain why.
By the way: I'm using CM7 with the nightly from yesterday
i am also using CM7, but the beta 6 version. I will try this test. I have two different charges, one original and another not, i will see if it behaves the same way you are saying. i will post my results soon.

same here..
Possibility of charger voltages rating differences giving out the output here I guess.
The original charger has been calibrated with just enough voltages/current to supply the phone during charging whilst the non-original charger doesn't have the exact voltage/current needed by the phone during charging thus giving the phone all sort of problems. One may see the non-original charger has label the right rating as per the original label but that doesn't give any warranty it work exactly like the original charger.
I recomend to use only original charger to avoid any damages may occur to the phone.
If one using original charger and still having phone behaving strangely. It may be caused by the phone itself(hardware issue) or the original charger(manufacturing defect) which by this mean you're one of the unlucky owner.... get a replacement ASAP..
I'm not sure about running firmware as such Eclair, Froyo or custom rom would do anything about charging side effect here.
I thought, that an intelligent power management only takes as much current as it needs. My adapter has 2 outputs (max 500mA, max 1000mA). I would expect the phone to work with any of these. When I plug in my navigation unit it works perfectly.
I'll take the adapter with me and try it with the original Defy of a friend. If it works with his phone its a software issue if not I'll have to look out for an alternative charging my phone in the car.
i deeply tested last night, charging with the original charges let the phone 100% useable without any lags while the usb charger kept me having lags and keeping the phone without any good responsiveness. No more usb chargers anymore
same here, original charger (btw, that is ALSO a USB charger...) works, but aftermarket charger, screen no (or little) response.
when connect to pc, works so-so.

don't expect every gadgets will work on any universal charger. The exact rating counts on a delicate devices specially on touch screen product. Grounding too must be equally the same from the charger to the phone which would result non side effect on using while charger is connected. Avoid using local based charger if possible as it could save your phone from damaging. Buy original if you really need it.

this happen to me too sometimes, but not all the time
I apologize if this is a dumb question, but I'm not exactly an electrical engineer. I was looking at buying one of these for my room: http://www.thinkgeek.com/gadgets/travelpower/e81a/ and it says it outputs at 2 amps. i notice the stock Samsung charger is 1 amp. Will I be doing any harm to my phone by using the wall outlet vs. my stock charger? Or will it detect it as a USB charger, charging it at a slower rate?
Ya it'll be fine, it says UP TO 2.1amps.
Also it says it charges all mobile phones that accept USB power.
yes it will work. I have a few of these installed in my house. Your device will only pull the amount of amps that it needs. The voltage is what you have to look out for...
it will work, but it is not up to the 2011 nec code as it doesn't have tamper resistant shutters, I would recommend this instead.
http://www.amazon.com/Cooper-Wiring-Devices-TR7740W-K-Combination/dp/B007NC5GI4
It works the same, is up to the latest electrical code, is cheaper and will work with a standard wallplate.
Thanks for the input everyone, I think i'm gonna spring for one (may not be the Thinkgeek one though, as the one cade80 posted and a few other's I've found are cheaper) at some point, just to cut some clutter from my bedroom a bit.

Although you lose 1 standard plug, the big plus is being able to use normal faceplates with it.

Be aware, this Cooper one is only 0.7A ... it won't charge an iPad 3 and is slower to charge then the OEM Samsung charger.

Good eye on that, depending on your needs this may outweigh the being up to current electrical codes.
most third party charger will not charge you samsung smartphone at full power.
to charge at full power you must shortcut middle pins.
"will not charge" - not correct, your phone reduce it
So I went ahead and decided to not spring for the ThinkGeek Charger, and instead bought one of these: http://www.lowes.com/pd_369050-6337...&pl=1¤tURL=/pl__0__s?Ntt=usb&facetInfo= and just put it in a standard plug to test it to make sure it worked. Well I plugged it in and the first thing I noticed was the GNex was taking a while to recognize the plug. Finally it started Charging (USB Though) which was OK with me. Well last night I plugged it in via my Samsung Charger to a standard power strip because I hadn't gotten around to installing the RCA plate yet. Well I woke up this morning and it was on like 50% power and wasn't charging. So I was like WTF. So I brought it into work with me this morning, and now when I plug the stock Samsung charger with the stock samsung cable into the wall, no charge. I tried plugging it in to my computer, and it eventually makes connection with the computer (it's not instant like It used to be) and Android File Transfer starts, but says it can't connect to the phone. Then it charges for a few minutes, up about 1%, then stops charging. So my question is, when I plugged in my phone to the RCA charger last night, did it fry my phone? Or is my charge cable maybe bad now? I haven't tried another cable yet (everyone at work is an iPhone user and doesn't have a Micro-USB cable lying around) but I'm going to try that and hope it works. If it's not the cable, is it possible that the phone itself got damaged? If so, how could I go about removing root and wiping it to take it into the VZW store for replacement without USB to the computer?
Another new development. I plugged it into a Windows Box (I was using a Mac) and when I plug it in, it says "This Device can perform faster" and talks about plugging it into a USB 2.0 port. I'm using a 2009 Macbook Pro, it has USB 2.0. It won't mount the disk either. So i'm really beginning to wonder if the USB cable is fried.
Turns out it was a bad USB cable. Went to Best Buy and bought a generic cable and it now charges and hooks up to the computer just fine. My ADB doesn't seem to be working though for some reason, on Mac or PC...
Ok, everything is working now. ADB wasn't working because of a conflict with EasyTether on my Mac. Thanks everyone for the suggestions but I've decided to just stick with what I have now (power strip) and not deal with it.

May I recommend you return the Best Buy cable and go to monoprice.com?
I bought five cables from them that are 6 foot long. They work terrific and are higher quality looking than what you get from Best Buy.
When I plug in my power adapter to charge the tablet more often now I get the Slow Charging notification that says battery is charging slowly due to low electric current of TA/USB connection. Any one else seeing this? I am using the stock charger supplied with the tablet. I have tried this on several AC outlets in several different locations. It does not seen to affect the ability to charge the tablet it just charges it a little slower.

Thanks for the reply. I am starting to think my power adapter is not putting out the correct current it should be. I will try using a different 2A charger and see how it goes.

You might also try a different cord!
You may try to install "battery monitor widget", it will tell you charging in USB mode or AC mode.
I also find the stock LG charger slow charging, the widget shows I'm only charging at around 1100mA max. While the charger itself label said Output 1.8A max. I can't reach this level yet.
If I charge with a stock nexus 7 charger (which is 2A rated), it'll get worse...just reach around 800mA max.
I'm still not sure what's wrong with the charger or the tablet itself...
I can say that the cable that came with the gpad does charge faster than a thinner cable I had. Both were tested plugged into the stock LG charger.
Sent from my LG-V500 using XDA Premium HD app
When I pulled my g pad out of the box and saw the stock charger was below 2A I put it back in the box. I charge my tablet with the 2A charger that my note 2 uses.
I've seen this problem intermittently with the stock LG charger and today it seems to have become a permanent fault. Swapping to my Note 3 charger things are back to normal once more. Swapping back and forth repeatedly the LG charger triggers the warning and the Note charger is fine. It looks like the LG charger is a bit rubbish. I'll press for a warranty replacement.
I have noticed mine recharges really slowly as well. Using the stock charger, and the battery app previously mentioned, it gives me about 1.1A from the stock charger. Using my Vita charger rated at 1.5A I get about 1.4 into the G Pad. It seems their charger just stinks.
I sent them a support query to see if they will replace it without hassle, if they want me to send it back I'll just buy something else instead.
Edit: Heard back from LG, they want me to send the whole thing back to them or return it to Newegg. Not sure why they won't just ship me a replacement charger, it would be much cheaper for them in the long run.

Further investigation revealed the original cable to be at fault, as it would not make a data connection with either of my laptops. Another cable from my old Galaxy Note worked perfectly. Even so there is still a question mark about the charger as well. Today I spoke to an LG support rep who promised to send a new charger and cable. They should arrive within five working days. I had read of mixed opinions on LG's support, but so far it all seems encouraging.
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!
Semper Fi
So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.
It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass
Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.
Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).
So how the story ends? We're you able to solve the problem?
I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer
Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-
I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
