Tablet is always "charging" even when unplugged

Hello, all.
I have a friend with a Nexus 7 2013 (WiFi) that she recently purchased refurbished. After some issues with the charger that they originally sent with the device, she finally got it charged and now it always says that it's "charging" even when it's unplugged. She tried doing a factory reset, but even after going through all that, it still says that it's charging regardless of whether it's plugged in or not. I also recommended she try letting it drain totally to zero and then charge it again to see if it was something it could be tricked into forgetting. I also went into the stock recovery and cleared the cache, to no avail. It is fully updated to Lollipop 5.0.2 with a locked bootloader and stock recovery and seems to be in good physical condition. If anyone has any suggestions I would really appreciate it.

Curious if something could be goofed up with the wireless charging coil.
When you go into the Battery screen (two finger swipe down from the notification shade, tap the battery icon) what does it say at the top? If the battery icon shows charging, it should list how it is charging in the battery screen, AC, USB (I think) or wireless.
Another suggestion might be to unlock the bootloader and flash the factory images direct from Google. I know you said that a factory reset was done, but I'm guessing it was done "onboard" without a PC. Reflashing the entire image could help clear up any cobwebs.
Unlocking the bootloader will induce a factory reset, but if one was already done, it seems like your friend would be OK with trying it again.

@fury683 I tried checking the battery stats for which charging type it believed it had and it says "over USB" so I guess it thinks it's plugged into a computer (probably due to the low (lol) amperage). I'll talk to her and see what she thinks about unlocking the bootloader and flashing the factory image, but she bought it from Amazon so I think, unless someone else can think of anything to try, I'm going to recommend she tries to get it replaced because Amazon's CS is awesome. Thanks for the pointers. If she doesn't have any luck with Amazon, I'll proceed from there.

If a return/exchange is possible, I'd go that route. As for unlocking the bootloader, it can be relocked when you're done flashing the factory image. However once it is locked, unlocking it again will require another factory reset.
Having it unlocked allows for flashing of other ROMs and recovery, as well as easy rooting. If that isn't needed and the user is OK with waiting for OTAs (the 5.0.2 one seems to be taking quite a while for some users), relocking it would be fine.

Did anyone figure out this issue? My nexus 7 started with this exact problem this week. Always shows charging (usb). It will never fully charge, via wall charger or wireless.

I had a 2013 Nexus 7 and it did this when I took it out of the box. It seemed to be a hardware issue. I was able to warranty it with Google. Sorry this is probably not helpful to you since the warranty period is probably over, but at least it probably brings conclusion to your issue.

I was luckily still under warranty, hopefully the issue will be resolved.

My Nexus 7 2012 has the same thing. I tried to replace the USB port, but got no luck. I tried to remove the battery wires too. I think this might be a issue with bootloader. When I plug it on my PC, nothing happens.

[Q] Help!!!!! Screen going on and off idk what to do!!!

first of all thank you for taking the time to read through this.
Yesterday I woke up and reached over to check my LG G3. I had left it charging overnight as I usually do and while the phone was still plugged in and I tried to go through my notifications, the screen flickered and went off. I was puzzled cause the phone was fully charged and the screen has no cracks and barely any scratches. I was trying to restart it and the LED light started flashing as I heard a notification sound.... I proceeded to take out the battery hoping thatd help out and nothing.
I thought my LCD took a **** on me but I tried to restart the phone once more about an hour later and then the LG logo came on shinny as ever. Then the AT&T logo, I thought all was well but then the screen flickered again and went off. A few moments later I started to hear more notification sounds and I saw the LED light start blinking.... everything in the phone works except the screen.
I changed my sim card to an old blackberry knock off so I wouldnt be cut off from the world while I went to work and when I came home I tried to play with it once more and the phone started working normally! As I was playing with it I raised the brightness and the screen started to flicker again but did not shut off. I immediately brought down the brightness and the phone seemed to work normally I then tried to open the camera and the screen went off completely same happened when I tried to refresh an app. What could this be? the battery? currently I the screen doesnt stay on for more than 10 seconds and does not work at all when plugged in to charge
Also in the last couple of weeks I was experiencing overheating but I assumed it was because of the rise in temperatures and the fact I spend most of my day outside and Im constantly using my phone. I am also guilty of using my phone while charging.
Any input you may have is going to be helpful. I need to figure this out as I use my phone to work more efficiently.
Thank you in advance!

I am having the same issue. I'm going to contact LG about this on Monday.

got answer ?

Yeah, they changed the entire display and said that the error could come from a defect battery. So i bought a new one and hoped for the best.
I still had the error today. I will try installing another rom so I can be sure it isn't the software.
Or else LG will be getting it again.

Well, they got it again... Twice. They changed the LCD panel and the mainboard. It seems that the latter fixed it. I got it back on Saturday and haven't had any problems since then.
Fingers crossed

I forgot about this post but I used my warranty last year and got a new phone or refurbished. They didn't tell me. Here I am a year later with the new phone and the same problem came back. The only thing that seems to work is baking the main board at 350 for 10 minutes and letting it cool down in the oven for 30 yet the problem comes back. After a week or so. I'm convinced the overheating of the phone is he culprit

Reboot after unplugging from charger.

I just got a warranty replacement from Google (original 5x fingerprint scanner just quit working) and I just noticed that if I pull it off the charger it'll reboot right away. I flashed the May update when I received it but I haven't seen anyone else mention the issue so I'm assuming it's not that. And I apologize...I haven't really had time to try any of the typical troubleshooting steps like reflashing the update or a factory reset (in-laws are in town). Has anyone else had this issue before?
Edit: I'll add that it's got to be plugged in for 5 min or more. Any less and it acts normal.
Edit2: aaaaand never mind...it's back.

SM-P605 cannot charge

Greetings, I have a bit of an issue with my tablet and it's most likely a hardware one.
About two days ago I had my tablet completely discharged and I put it on the charger. I saw the battery and lightning screen and left it for about a day.
Then yesterday I wanted to watch a movie on it and so I reached for it and all it had was a black screen. I thought that it must have charged up completely, so I pulled it out of the charger and started it up.
It then went as far as the Samsung logo and 20-30 seconds afterwards it shut down. I thought that maybe my ROM became faulty or smth and tried to boot into TWRP. Same thing.
Booting into the Bootloader worked but at one point the screen started rapidly changing its brightness. And it again turned off after a couple of seconds.
I tried this several times, connecting it to the wall charger or my laptop but every time it turned on for only a couple of seconds and now it has completely died off. No matter with which cable, charger or power source I try to charge it, it doesn't light up at all. Power button and combinations with volume buttons don't do anything.
A bit of info about the device: It's about 2 years old running the latest LineageOS. Roughly 1 year ago it suffered a drop and the screen got cracked. I ended up buying a spare screen from China and gave it to a hardware specialist to install it. (Samsung doesn't really have representatives near me, so that was the easiest option) Ever since then the speakers have always been a lot quieter and worse-quality but everything else worked fine.
I believe that somehow the charging circuit fried itself and now the battery has died off. Is that even possible? I haven't charged it with any unknown wall chargers or anything that could fry it. Can someone please help me fix this problem since I have no idea where to start?
Thanks in advance...

You might want take a look to this topic of mine. Not exactly the same problem but the resolution might apply to yours as well.

Thanks for the suggestion, but your tablet can at least boot. Mine can't, which is the issue and it doesn't charge at all when off.

That's why I pointed you to open it and resettle all the cables, as I did. The problem is different but the solution might be the same...

nexus 5x dead

My mother's nexus 5x has just died.
no fastboot no recovery nothing.
I have tried to charge it, but after more than an hour connected to the charger still nothing.
I checked that this charger works on my nexus 5x so it's not the problem.
I also tried to connect it to a computer, but the computer detected nothing.
the phone had 7.1.2 stock (either april or may security update I don't remember which one).
Anyone has an idea why it happened or how to fix this?
Thanks,
Orma

Wow, my 5X just died this morning. Wonder if it isn't just a coincidence or maybe some update like to the Fi app or something messed it up. So I'll post in case others have also had the same thing happen. The Fi app was last updated May 8, so that's not it. But maybe there was some other app or something updated that caused problems. Some of the core apps were recently updated and my phone tried to update some behind the scenes type app, but it didn't work. So I tried manually and it did work. Maybe I shouldn't have done that. Can't remember which app, but checking on my Google playstore apps, maybe it was Google Connectivity Services.
Mine was fully charged and I was using it while still connected to the charger after waking up in the morning. It just went black suddenly. I tried holding power button to shut it down, but it never made any vibration as if it was force shutting off. Power button and volume down button didn't work to shut down or boot either. The computer recognized it the first time I plugged it in showing Qualcomm HS-USB QDLoader 9008 has completed setup. But after that it would show as device unrecognized.
The only way I got anything to look like it was starting ok was by disconnecting the battery for a while. Then it started booting and then the screen just went black again. I unhooked the battery again for a while, reassembled, and plugged the phone in and the battery charging screen showed up, but then went black again without showing the filling up graphics.
So it seems to momentarily kinda act ok, but then soon goes black. Disconnecting the battery seems to reset it to a state where it can try again.
The battery read as 4.16 volts, so seems to be fully charged as I thought it was. I'm going to try doing the battery disconnect again, but I'm thinking this thing is done.

This may not just be a random thing. Several people on Google forums have the same sounding issue from yesterday or today.

By disconnecting the battery and then reassembling, I was able to get to the recovery menu. I chose Restart Bootloader, and after a few moments, go a screen showing the android character laying on the ground with a triangle with an exclamation point and "No Command" text at the bottom.
Holding power button and volume down got it to go back to the menu.
So I tried Recovery and it showed Google in white letters, then went black. Trying Start does the same thing.

This problem is common in the Nexus 5x, I advice you to check the warranty

if I open the phone to disconnect the battery will it void the warranty?
any one has any idea on why it happened?
my nexus 5x is totally fine
edit: I tried again to turn it on, but this time the notification light turned red, so i tried to connect it to the charger again and it seems to be alive now,
that's really weird but it turned on with 1% meaning that for some reason when I charged it yesterday it wasn't really charging

Sounds like you got lucky.
As far as I could see, there is nothing inside the phone that would indicate that you had opened it up. There's no glue, except under the battery, and maybe under the motherboard. But you don't need to lift those to disconnect the battery connector. However, it does require prying the back off and then unscrewing 10 screws. Then lifting off two pieces with stuff like the fingerprint sensor and speaker attached to them. If you make any dings in the plastic back cover while prying, they could see that. And the screws have lock tite on the threads so take some care to remove. I think I slightly stripped the top of one. So if someone really looked, they could see that. But otherwise, except for leaving fingerprints on parts or debris or whatever in there, I don't think they'd notice. I highly doubt they'd have someone go check for other than obvious signs of prying the back off. I'm 2 months past warranty so it was a non-issue for me.
Following someone's advice on the Google forum, I cooled the phone down in an ice bath (in a bag of course) and was able to get it to boot to recovery and even installed the OTA via adb. It then booted to the point of the 4 colorful circles and died again. After putting it in the freezer, it then returned to acting somewhat normal, as in it showed the battery charging graphic while off. The battery is about 1/2 full. But then I booted and it would get pretty far into the 4 circles spinning, then boot looped. So mine is bootlooping and I'm going to see if I can get Google to step up even though it is 2 months past warranty since I bought it from them. The Google people say to contact them with the bootloop problem. I hope they are quietly replacing them since this this appears to result from the last OS update for many people.
That other person was able to boot it and pull their pictures off it. But looks like mine is down for the count. I luckily had backed up pictures and most of my other stuff recently before I went on a trip. And I uploaded pictures while on the trip and pulled pictures off the phone right after the trip. But I've lost some info that I hadn't copied off the phone.

I'm 2 months out of warranty, so I hope Google does something since I bought it from them and they seem to be providing some relief since this seems to be due to the most recent OS update. Or at least some of the people in their forums seem to imply they'll do something.

Well here you go. Explanation was at XDA all along. There's a class action lawsuit against LG for using solder that didn't withstand the level of heat or heating and cooling cycles. Started with the G4, but in April the 5X and other phones were added to the class action. So I guess I could try touching up solder points and get my phone maybe to start up, or try for warranty repair since they seem to have extended the warranty because of this lawsuit.

One guy at bottom of this thread has screen capture and says his 18 month old 5X shows as covered by warranty in their system.

Same here.
Nexus died after some freezes. After 7-10 failed boots it suddenly booted, just to freeze again after 1 or 2 minutes.
Tried every button combo with and without power plugged, no luck at all, just a dead brick with no signs of life at all.
Device was perfectly working till yesterday. No issues at all
Latest purenexus version. Everything was fine.
Don't get it.
Only thing what came to my mind was that we have been to the beach the day before. Had the phone in the backpack, but it went still really hot since the sun was strong.
But hey. Have been to definitiv hotter places last year in Croatia.
I thought i try the revive Motherboard in oven trick, since this oven thing already worked once for my laptop graphic chip which died also from overheating.
Put the MB in the oven for 12min at 200C.
No luck. Dead brick.
Any ideas?
Thanks for reading!

When my Nexus 5x died, LG replaced the motherboard and then everything was even much better than before.

LG has agreed to extend warranties on a case by case basis after they were sued. One lawsuit was dropped as a result, but the other remains. So they may be more willing than usual to fix it without proof of purchase, but only way to know is to call them.

If you can't get any warranty help, then you can try the heatgun method. This seems to basically melt the solder again so that it'll work. If you're lucky, you get the one or few connections that are messed up.
Using a heatgun, I got mine from completely dead to where it performed normally for 9 hours. I thought I was back in business until it rebooted. Then it lasted a bit before rebooting, and every time would get shorter and shorter before rebooting. Now it is bootlooping at startup, but still alive. So I can adb the OTA back on there, clear cache and factory reset. And it charges. But it just bootloops.

By they way, I tried a hairdryer for 30 seconds and it did boot to where I could unlock it, then it froze. The hairdryer just doesn't get hot enough to melt solder and only just heats things up to where there might be a temporary restoration of whatever connection or solder is broken. So I tried about 2 minutes and I could boot and swipe one screen left before it died. The heatgun took 1 minute 30 seconds to get it to where it would boot and work. I'm not going to go at it again since I have a chance at just getting a warranty swap if they extend it since I'm 2 months past the year coverage.
