Hello everyone and happy Halloween! I have myself a Nexus 10 running CROM Kitkat v7.1 with KTManta Kernel 3.4.86, bought used off Amazon. A while ago, there was a power surge, and my tablet didn't charge for about 3 hours. I restarted it many times, and finally, it charged. Ever since then, OTG doesn't work, the port doesn't output power anymore, (tested with known working flash drives and hard drives) and the tablet doesn't recognise it is charging for any amount of time from a few seconds to roughly 5 minutes. If I use the tablet while charging for anything other than light internet browsing, or I turn on auto brightness, it stops charging, then stops responding to touch until the charger is unplugged from the tablet. I'm pretty sure the surge fried something, but what? And why does my poor Nexus act so bizarrely while charging?

Hi,
Happy Halloween for you too . Well, I'm sad to tell you, but it seems like a hardware problem. As you said, the tablet didn't want to charge, neither it is able to output power to the OTG anymore. I believe it is was caused by a current peak during the surge. And that probably messed up with your tablet charging port, messing with it is probably sending bad voltages and current on the battery, which can damage it and cause overheating and such as well.
This was my quick diagnostics. I'm not so sure about it, but everything leads to this idea. I'm pretty sure asking you to reflash stock would be useless. But it's worth a try. If the problem is really hardware, then the solution is pretty obvious, and unfortunately hard. Send it to a Samsung costumer care or buy the pieces and try to solve it by yourself.
I'm sorry for your tablet, and wish you can fix it!

Yeah, I was hoping it wouldn't be a hardware issue, but I'll try stock, and if that doesn't work, I'll have to go and see how much it costs to fix it... Thanks! And Touhou is quite fun!

I cannot help with the OTG. For the charging, are you using the micro USB or charging using a pogo cable? If you are not using a pogo cable, you should buy one and try it.

Hi Anybody!
I have a Nexus 10 - which works normally by the way for the past 2 weeks now.
Unfortunately, today I was playing with a certain solitaire app while the battery is already in RED territory (a few % battery life remaining) while the Nexus 10 is connected to my PC via USB.
Since the USB charge is only 1 Ampere, I am aware that the charging is weaker (or slower) than draining since the screen is on and an app is being used. But my assumption is that the worse thing that could happen is that the tablet just goes dead and should be able to re-charge normally after.
However, my tablet has been connected with a 1-Amp (Galaxy S3 micro USB Charger) for the past 30 minutes and until now the charging logo is not popping. When I press the power button all I see is the Empty Battery Logo (Gray) with a Lightning Logo (black) with no animation (animation - emphasizing that the battery is charging) ... I am currently worried that the tablet went on a full-drain and is now one piece of useless sh*t.
Should I leave it alone for the next hour to see what happens? Because I sense that this is not normal, and by now the battery logo should be showing some animation that it is actually charging.... HEEEEEEEELLLLP
Btw I am using GS3 Charger because the Nexus 10 Charger (2.5Amp) uses a 110 voltage, however we only use 220 volts here at home (non US country).
Someone please advise... thanks!

Are you sure about that? Because my charger will take from 100V-240V.
Try to get an adapter. At least for my Lumia900 I need the original charger to wake it from the dead .

I am definitely sure it's only 110 Volts because I bought the Nexus 10 from the US and it says in the adapter "110"... while the other adapters from the Galaxy Note and S3 Chargers says "110-240" just like yours... so i wouldn't want to risk plugging the Nexus 10 charger adapter to a 220V outlet and risk busting the adapter.. or worse the Nexus 10 tablet.
Currently, I am asking someone to look for that damn forsaken 220-to-110V transformer which I used for the "Play Station 1" a decade ago... just imagine..... how long that was. I hope that transformer still works.... or I'll be damned. as of writing, the symptoms of my tablet still remains the same..... F*CK~!

HELL YEAH! Nexus 10 is now working. The issue is simply that the tablet over drained so drained that it has no power to display the batter logo animating to show it's charging.... Lesson Learned, Patience!
Moderators you may now close this thread.
To Samsung / Google: Please distribute your Pogo Chargers ASAP! Also, a question has been lingering in my head, What if you connect the Pogo Charger and USB Charger at the same time to your Nexus 10? What will happen?
Off topic but phone arena just said that the battery life on the Nexus 10 is way better than the battery life on the ipad 4. Weird, I feel that the Nexus 10 is about the same as my ipad 3 was, maybe slightly better. Twice as good though, definitely not mine. Does anyone have this crazy battery life version?
my nexus7 will not charge until it has completely drained....
I am aware of the current battery problems, but mine is a bit different....
Even after going to bootloader and choosing power off my nexus will sit on charge (wall) overnight and be dead in the morning, even though it was at 30% when plugged in....
The only way to charge it seems to be off my laptop. but even then it takes over a full day to charge.
If i hook up to laptop while runing it basically only slows down the drain but still doesn't charge up....
this is very frustrating, and i'm at my ropes end
would dowgrading to an older rom take care of this issue?

No solution, I'm afraid, I'm chiming in to say that I have also been having problems since the same time. For two days, I have been trying different combos of chargers, cables, and outlets, to see if other equipment is the problem. But all of it works fine with my Nexus 4. Mostly, I am experiencing that the unit says "charging" but the battery level is going down instead of up. I managed to get a full charge overnight by using an external battery that I got just for this type of emergency backup. After use, it is back down. This morning, third cable I tried finally seems to be working, for now. In 40 minutes it went from 63% to 65%. I am somewhat relieved but this situation is not normal.
I'm going to start reading through the forum to try some suggestions. I wasn't paying attention to updates. Has this problem been triggered by a recent update?
I understand some suggestions call for letting the battery discharge entirely. It seems that won't be hard to do. I can leave it plugged in and, as happened with most of the cables I tried, the battery level will go down to zero pretty fast. I'm really annoyed, but very happy right now that I splurged on an external battery.
Have you tried a new charging block... That would more that likely be your culprit.

Check your port for bent pins.

I used three different chargers plus the external battery. Two of the chargers have two inputs (i.e., for Apple and non-Apple products). I have five different charging cords, longest is 6 ft and the others much shorter (two are from Monoprice), and one retractable I usually use in the car. I tried every combination I could think of between chargers, cables, input ports, and several different electrical outlets at two locations.
All the various combos functioned fine with my Nexus 4, the other device I have with me. None of them worked with the Nexus 7. All showed as "charging", but they weren't. In some cases, the numbers were going down quote rapidly. Goes without saying, when you're charging, it shouldn't go from 64% to 59%.
The thing that finally worked - with no hiccups - was the external battery. Since everything worked on the Nexus 4, it's quite apparent the problem is the Nexus 7.
Having said that, by this morning, things inexplicably changed for the better. With the device at around 70%, I connected one of the chargers and it functioned normally. Battery filled up within the normal timeframe. I was using it intermittently while charging, as I often do.
I'm glad it's working and very glad I have the external battery that can fill up both the Nexus 4 and Nexus 7 in a pinch. But I still think there's something wrong with the Nexus 7, and I'm not knowledgeable enough to dare try some of the more technical suggestions. Just the term "shorting out the pins" is enough to warn me that I'm not expert enugh to try anything like that. For now it works, I hope it lasts like that until perhaps I can understand the issues a little better.
I'm having the exact same issue as you guys and it has me stumped. On some days it'll work, others it wouldn't. At first I thought I could fix it by rebooting but last night mine just drained all the way down overnight while charging from around 50% and this morning I wasn't having much luck getting it charged using the 2 stock Nexus 7 wall chargers that I have. I'll try using an external that I got recently and hopefully that'll solve the issue for now at least.
Edit: Some people have had luck reversing the polarity on their charging block. I'll give that a go and report back whether it worked for me or not.
Edit/Update: Yup, flipped my brick around so that the big end sticks off the left side and it's at 32% now from 0% after 2.5 hours. You guys might have some luck with this too.
Nexus 7 fails to charge
We have two Nexus 7 in the house, one 11 months the other 6 months old.* The older one stopped charging just before our holiday last month so we took the other. It stopped charging while we were away.* Fortunately my wife had here Samsung Ace [mains] phone charger with her. This worked every time.*
Once home I checked the two Nexus 7 mains units and 2 Nexus 7 usb cables. No combination would charge either Nexus 7.* The Samsung mains charger would always charge both Nexus 7.
Solution:* Suspicious, I ordered an Asus Nexus 7 cradle while we were away. Any combination of Nexus 7 mains unit and usb cable charges both Nexus 7s on the cradle.
Conclusion: The USB socket on the Nexus 7 cannot take repeated insertion and removal of the cable.
Hope this may help somebody.
Yea I had the EXACT same story as you. I had for got to take my nexus 7 charger on holiday but I had my Samsung galaxy ace (s5830i) charger so I used that. when I came back and pluged In my charger It said that It wasn't charging so I used my brothers nexus 7 charger but still no good. It said that my brothers nexus 7 was charging but not mine and than I figured out what I had damaged... My nexus 7 charging port. I had proved this by comparing the the 2 charges and they where very different... Luckly It was still under warranty so I took it to (I cant tell you that). I looked all innocent and pretended I was new to this stuff and they then tried to charge it but no use so they replaced it with a new one but now I know not to put different chargers in my new nexus 7 and that goes to people out there as well

Ok, so at one point, my Nexus 7 started taking about 9 hours to fully charge using the stock charger and usb cable. I thought my charger was dead so I bought a 2.1 amp amazon basics charger with a 6 foot amazon basics usb cable. It still takes hours to charge. I read online that there was a bug with Android 4.2 and charging. The reason this CANT be a hardware issue, is because it happoned out of the blue. Didn't drop it, didn't jerk the cable or bend it in the inside or anything. So what's going on? Please help!
Thanks in advance!
P.S. It looses charge when charging and watching a YouTube video now. It never used to do that.

as far as I know, it is a known issue with 4.2.2. I don't think upgrading chargers will work, I tried my iPad's still takes forever to charge. For some reason, the original USB cable works better (at least for me).
Did you install custom ROM's with overclocking maybe?
I suspect it is most likely the micro USB or the battery as my Android won't charge anymore. I saw a video on how to fix this but I don't have the part or know where to find it. My device is a Nexus 7 ASUS. If the micro USB isn't the issue than I don't know what is wrong or why my Android won't charge anymore.

Hi, MASF123...
It might not be the Nexus 7 itself, the problem might lie at the charger end.
I had a similar problem several months ago, where my Nexus 7 either wouldn't charge at all, or it would charge erratically, and thus taking hours to fully charge up.
It turned out that the fault was a loose USB socket in the official Nexus 7 charger that originally shipped with my device.
Anyhow, I started to use a spare Amazon Kindle charger that I happened to have lying around, and my Nexus 7 has charged without problems ever since. It's rated slightly lower (1.8 amp's) than the official N7 charger (2.0 amp's), but it gets the job done.
So it might be worth trying another charger, perhaps from another device, before you start tinkering with the Nexus 7 itself.
Hope this helps, and good luck.
Rgrds,
Ged.

No that is not the case because I bought a new USB cord and power supply to make sure before I opened it up. It stopped charging even with the new charger I bought.
My phone is two months old and has ceased to quick-charge. Actually, 90% of the time, it will only charge when powered down. I use the factory charger and cable but get a message that I need to use the original charger and cable. Catch 22?
I bought it at Best Buy so I took it back to them this evening. My charger is fine as is my cable. Best Buy confirmed that my issue is a factory defect and politely sent me on my way. I take care of my phones if nothing more than the fact that I've had to replace micro USB ports in the past. The weird thing is that when it charges powered down, it seems to refresh to full battery very quickly.
Has anyone else had similar issues? If in fact, I do have to deal with ZTE, what has been members experience?
Thank you for letting me vent.

U can test your charger using USB volt amp reader on another phone which supports quick charging.
If charger works as it should then u need to test your phone with multimeter to see how much current it draws while phone is powered off without charger (battery only).
But that means you need to open 2 month old phone which i dont recommend if u have warranty.
Axon 7 draws about 2.66-2.68 amps while in quick charging mode. Volts i forgot but i think it was 6v. I'm not in shop at the moment so i cant know exactly.
But for amps i remembered.
Wallor77, thank you for your reply. My charger is in good working order. In fact, I have several 2.0 and 3.0 chargers. They all work fine on my Samsung Galaxy Note Edge. The Samsung displays "Fast Charger Connected" on the lock screen.
Now my ZTE Axon 7 will not charge while it is powered up. As soon as I turn it off, it charges just fine. This is really annoying!

If your charger and cable are OK, perhaps have you recently installed an application which limits the power. Such methods exists in some antivírus to preserve the health of the battery. It's just an idea.

Same thing there. If it charges normally while power off u need to see how much amps. USB volt amp reader is a good little device. I recommend for everyone to get one. It cost about 15 bucks. From there it's all about elemination process to diagnose proper issue

I second this. But $15?! You can get them for about $5 on aliexpress!
U have USB volt amp reader with both volt units, amp units, time duration and mAh over time charged value. But 15$ was about avarage price listing. I'm sure there is cheaper as well.
UPDATE: 6/2/17
I ended up sending my phone to the ZTE repair center in TX. It took about 3 weeks to get it back. There was no explanation of what was repaired and I received my original phone; not a refurbished one. All I know was that it was covered.

I am in the process of returning my 3rd Axon to ZTE. 2 of them have had this problem. It's definitely known because when I was talking to them and told them what was happening they just kind went "yeah ok" and fast tracked the whole thing. Thank god for this warranty, their quality control is ****e.
anyone noticed that occasionally it stops charging?

Last night, mine started doing this. It goes on and off about every two seconds. What's weird is it only does this with the quick charger. it slow charges when connected to a PC usb just fine. Its not the OEM charger either since my wife's quick charges just fine with the exact same charger.
Guess I'm going to have to call ZTE....
Mine suddenly stopped quick charging - I have 3 different chargers that work fine with other phones except for this one. And chances of all 3 of them going bad at the same time are slim to none. Tested different cables as well, but again same result. It charges with normal speed even when connected to QC3.0. Tried wiping cache. I think it's no different if I turn the phone off. Think it might be time to move on. Had it since December 2016, so I guess it's nearly 2 years old now. Still shame.

Quick update. Swapping batteries (OEM) hasn't helped. I wonder if this is software or hardware related
Let me add to this thread. I'm also not getting quick charge anymore for maybe a month already. Tried different cables, booting to safe mode, etc. There are few instances where i see quick charging but very rarely. I was thinking it's my usb port but I haven't opened my phone yet to verify.
