[Q] Nexus 7 charges randomly and isn't consistent - Nexus 7 Q&A, Help & Troubleshooting

Hi guys, hope your well.
Been having this problem for the past month and its killing me since I use the Nexus 7 as an ebook tablet to study. For some reason it now charges when it feels like it. Times when i connect to charge on a wall outlet, it does absolutely nothing. I tried other wall outlets, I tried connecting to the pc and it wont detect it as a drive either. Some days it will decide to charge, other days it wont. I tested the battery on a android app to check its life, and it stated that its healthy.
At one point I had to remove the entire back cover for it to catch a charge. I even tried the "bootloader and restart" tutorial, no good. The Audio jack works perfectly fine as well, never had any issues with that.
Its really weird and I would like to fix this as soon as possible. Really appreciate your help guys. Please advise

Looks like there's a problem with the charging(USB) port of the tab.

Fix?

Car charger problems

I use TomTom on my Touch HD with a car charger.
The first charger I used was fine but since I lost it I cannot find a charger that works properly... At first I thought I was just using faulty charger's but as I have now tried 3 different ones I am beggining to wonder if the problem is with my HD!
The funny thing is that on both the main screen and in TomTom it is showing the status as 'charging'... even the light on the top of the phone is lit to show it is charging but the battery level is still going down all the time!
The only thing I can think of is that maybe the chargers I am using now are not as powerful as the first one I used? Or are all car chargers standard?
Either that or my HD is broken!
Can anyone please help me find a solution?
Ps. The phone still charges fine through both a wall plug socket and a USB connected to a PC.
The car charger I use I bought for my old Tytn 2 (original HTC one), works great for the HD and Diamond, even when the battery was at about 20% left on the HD, TomTom 7 running, screen brightness max, the battery was almost fully charged within an 1hr.
Think it's rated at 1amp, you might want to check the power rating on yours, anything under 1amp and it's really going struggle to charge while using it.
Unfortunately its not printed on any of my chargers what amp they are... I actually thought they were all the same amp but if some are more powerful than others this could be my problem.
What does concern me however is that even when the HD is switched off it is still not charging (even though the light at the top of the phone shows it should be!)
There are plenty of tools around (HTC's battery.exe, acbpowermonitor, battlog, powerguard, etc...) that can show you charge/discharge current. If your car charger gives you less than the unit is consuming, battery will not be able to charge.

I had this problem and found it was because I was charging through the usb socket on the stereo which always worked on Polaris but not with Blackstone. If I charge from the cig lighter socket it works good.

link the charger to the main battery under the bonet and you will recieve a quicker phone charge, usually a full battery charge will take 24 hours, link it up to your main battery and a full charge will be done ina matter of minutes, its genius

First I used my original HTCTyTn carcharger by trial. But he has not
enough power to charge and run TomTom at the same time!
So, i bought this new one (more powerfull) for the Touch HD.

I bought a cheap and cheerful universal usb charger from tesco's for a couple quid. Works great and no problems with power whilst running TomTom
Hi, first post here and rather than start a similar thread so soon, i thought it best to post here.
Is it possible for car chargers to over-charge the device? I bought a cheap and cheerful car charger off ebay but was a bit concerned some of them are listed as having overcharge protection and this one wasn't. Wouldn't normally be bothered but its a £550 handset!
Cheers!

My Note stopped charging! Advice please?

Anybody ever hear of this?
Started intermittently charge/stop charging.. Then just stopped.
Rebooted? Nothing.
I have an extra battery...tried that....same thing!
Finally I wiped everything and it charged again...all night (thank God... I was at 15%)
BUT....checked just a bit ago and it was intemittently charging and stopping again...now I'm back to no charging. WTF....lol.
Only other info I can offer is the that at times I've used a second nonNote android charger (meant for my hotspot device...that does output to 1.2 but I don't think that would do anything..I used it on my Galaxy 2 Touch for months.
If anyone can give any insights I'd greatly appreciate.
I cannot charge my Note at all rights now.
Have you tried a different charger and/or USB cable?
Regards,
Dave
Thanks...yeah 2 different chargers. USB...you mean charging via PC right? You know i haven't tried it believe it or not!
I'm sure i could wipe everything again and it'd work again..but...big pain!
Right now I have to wall charge the battery itself.
Hey OP, any updates on this??
After I flashed Abyss 2.5 on top of Cassie's V3 on my Note a few days ago it started doing the charge/stop status and I could ONLY charge it while off and even sometimes it was awakening it self up!! And finally it gave up to no charge at all.
As from yesterday is officially "dead" since no recovery/download mode can be entered because of low battery. "Download" mode say's too low battery and it can't download.
Hey guys I really need some help on this. NO external battery chargers are available to try and no one I know has another Note to ask to charge my battery..
What do you thing? Faulty hardware/micro-usb port or something? I'm NOT blaming anyone since it's not a widespread issue but this DID happened ONLY after flashing Abyss 2.5 from CF KKA.
Thank you for your help guys in advance. Please let's try and resurrect my NOTE!
P.S: Also I forgot to add that immediately after flashing Abyss 2.5 I lost USB functionality in any way while power on.
I also tried:
3-4 different wall sockets.
2 different working cables. Original and one SE brand. Both working on other devices.
Tried removing battery MANY times.. left from 20sec to 1-5minutes etc(despair yeah).
PLEASE any info/help would be GREATLY appreciated..

And risk of having my 2year warranty thrown because of root or custom rom which they can blame for my problem? I think otherwise.
When I manage to charge the battery I might put everything back to stock and take it for a check if the problems continue.
Btw, you response: "...Instead of asking people here..." got me thinking a bit.. It should made you think a bit too.. Why?
Because 95% of your problems can be solve from online research. Relatively speaking of course. The ONLY times I couldn't fix something by my self(speaking for electronics, but can be applied on many other different occasions) was because of soldering needs which then I have a certified friend with good soldering skills and he does the job for me..
Example: One Acer 7736Z I was repairing had a blown/dead power ic chip. I ordered it, my friend soldered it since I never messed with soldering and all good. Done.
Another example: I have a Sammy 59D550. I had some problems.. Should I every time that I have a problem find a car to transfer it to the repair center/shop or do some research online which in the end I fixed my problem with a simple firmware update..? I prefer the latter.
Please excuse the comment, I meant it in a more generalized way, not directly to you, but that "...Instead of asking people here..." got me a bit going. No offense meant.

A little update on my "situation".. Phone is charging and ALL thanks to ephestione. Also I followed the video below and did exactly on my note and it's charging as we speak..
http://www.youtube.com/watch?v=9pYcgmLhUcQ
Procedure: As it might help future visitors.
I cut a mini usb since as I have many spare.
Attached only the red(positive)/black(negative) wires to the phone's corresponding battery pin.
Forced the battery in to secure a good grip between them.
Connected the other normal USB end plug to my Note's original Samsung USD charger.
Phone is successfully charging for now.
I believe what I did was wipe all and reflash, ...and all was well.
I have found my Note and SGS2 to be pretty sensitive to chargers. What do you mean outputs to 1.2? You need it to output at least 800mah, probably 1000mah. I would expect the Note to draw more power than the SGS2 but I'm not sure. I bought a Rocket Fish (good quality usually) charger from Best Buy. It didn't even say on the box but output only 600mah and the phone acted just like you are saying.
One charger I bought from Walmart, if I plug it in the TOUCH SCREEN STOPS WORKING!! Crazy!
I have had good luck with blackberry chargers. Make sure the USB cable you use is good also. I have had some that worked great with other phones and not with Galaxy phones, even some that worked great with my SGS2 don't work so good with my Note.
wipe battery stats
i reckon you hard reset and stick to OEM batteries, and buy an external charger on ebay!
I am also having a charging problem but it is because any charger that I plug in is loose in the phone and only having it in the right position works. I have tried many different chargers but my port on the phone is just too loose. How do I get it to a Samsung repair shop? I called samsung and they told me they only fix phones that are ment for the US and my phone is an international version.

Unfortunately, Samsung does not service international note in the states. They do not train as their product is not officially sold.

So am I just out of luck getting my charging port fixed?
My note did the same thing. I took some compressed air and sprayed the micro usb charge port with it a few times. Worked like a charm. Remember if any of the pins don't make contact then it wont charge.
Know this might sound goofy but same thing happen to me.
2 things that im pretty sure in some combo, was the issue
1. USB port got dirt/debris
2. The kernel I was running. Im 99% sure this was the issue all along. I was running abyss or something like that.

Nexus 4 charging issue and wireless charging

So I've had my Nexus 4 for a couple months now and I've taken really good care of it. It's pretty mint. But today it refuses to charge and I have a phone interview for a job on Thursday and I really need this little guy to work. I have CM 10.1 and thought maybe it could be related to that in some way. Maybe it's just kinda glicthy right now? But the last time I was using the phone it died and I put it on the charger and an hour later it wouldn't turn on. I've tried 3 different chargers and none of them give me the little battery charging image or light up my LED notification light. Any troubleshooting ideas? If not, can anyone recommend a cheap wireless charger that works very well? Thanks for your help in advance, I really need to get my phone working immediately.

try your stock charger. Just leave it there for 10 minutes or so then try turning it on again.

what other chargers do you have at your disposal? Ideally you should use one with a rating of minimum of 1 amp. The stock charger is rated at 1.2 amps. For your case, if the 1 amp charger doesn't work, try a 1.5 or 2 amp charger for 30 minutes or so. See if that works.
Did you drop your phone or hit it against something?

[Q] fast charging issues!!!!!

soo my issue is the fast charging.
first few days it was fast charging everything worked fine after that it stoped fast charging. when i plug it in it dosent show "fast charge connected" insted it shows " usb ".... so i thought something wrong with the cable so i changed it.... so i changed just the cable not the plug works fine. my first thought is that the cable is broken or something,
1. can that be true that the cable is not proper build?
2. does it affect anything that i charge my phone with an older cable?
Just double check under settings, power settings, fast charging is still checked. Once I accidently uncheked it.

no no the fast charging is checked.... like i said with the cable that came with the phone fast charging is not working...... other cables yes everythings normal
That's odd because the cable has nothing to do with it. Maybe your stock cable has been damaged.
I don't know it's confusing to me too. because the first two days it was working great after that It's not fast charging . maybe my cable was bad made!! but fast charging is working with another cable l have from my old s3 !

Also does it affect something on my battery that im using an old cable for fast charging???
Sent from my SM-N910F using XDA Free mobile app
How do you know of fast charging is working? Thought the screen had to be off?
Yes the cable will affect fast charging. Fast charging only works with cables of certain gauge (thickness). You must have damaged your cable, or it was already damaged before you got it. Don't worry this has no effect on the battery, no degradation.

ok so the cable could have been already damaged...... the thing is when i fast charge it with the other cable it charges the same time as the cable that came with the phone.... i also noticed that i get the same battery life also...... sooooo i there must be no harm at all right????
rapid charging multiple issues
My Note 4 did the same thing: 1st charge worked great, then it started showing connected to the RC, but unable to charge and flashing LED. Sometimes it still charges okay (not rapid) and sometimes really crawls. The "not able to charge" plops up every few minutes. Word was that there was a chord issue with the OEM and that they were fixed, but replacing the ones that were shipped already with a problem. That didn't fix my issue. The new word is that it's a device issue in some cases. For me, it does appear to be the device since I've done a FDR and tested multiple chargers, chords, OEM and carrier options. Contacting Samsung today as a DOA device. I'll let you know what happens. :fingers-crossed:

If you are hooking it up to a computer to charge, you will not get fast charging. It has to be plugged in with the power plug only to get a fast charge.

I got a replacement device by warranty and it's charging exactly as it should. All of my cables and plugs are working.
Wow...it's fast...faster than expected even! I'm loving the new Note, now! Just one of those things that happens sometimes.
Good luck with getting yours working. I should think it would be covered by the warranty.
Happy holidays to you and yours!
replacement
How long did it take to get a replacement? Had my phone for almost a month now and its very on /off with the charging. When i first got it it showed fast charger connected and got 50% charge as advertised in half an hour. Now it will, if im lucky charge maybe 10% in an hour. Just now, went to bed with 13%. 5hrs later it got to 32%. Havent tried a different cable and plug combo yet.

Another thing to check, make sure the standard usb end is snug in the charging adapter. Mine wasn't fast charging, but it was slow charging (I think - showed lightening bolt in battery icon) and then I pushed the usb into the fast charging wall adapter a little more and it resolved the issue
Hey, I was wondering if you're still experiencing this problem; I have the same model number & have the same problem.

I've had my Note since December last. It was fast charging just fine for about a month then I noticed it became sporadic, then it went to slow charge after that, then stopped charging altogether.
I changed the cable and it started to fast charge again for about a month and the same thing happened. It just deteriorated over time until it stopped charging.. So this is what I've been doing since. I'm on my third cable now. I've been wondering if the higher voltage etc, that enables the fast charge feature breaks the cable down. Just a thought:confused.
I had the same issue when I just got my note 4 a few months back. It turn out to be the charger that is causing the problem. I went to the service centre (in Singapore), the reception told me it is a common problem with the charger. Had it changed and the problem solved.
fast charge
So my problem was that the first days fast charging was working then I deside to desable the fast charge and now I can't enable I need help

Battery doesn't charge until 100%

Hi!
I recently bougth a 1+5, I decided to charge it, but after one hour I see that the battery hasn't charged fully(only until 84%), I waited for minutes and I realized that the phone didn't recognize the charging mode.
I have charged many times but it only charge until 82-85% and I have to complete the 100% via USB.
Does anybody has the same problem and if it has, how could you solved it?
Thanks!

Yikes. Sounds like a bad charging brick or a bad OP5.
Have you tried using different chargers and cables?
Next option would to be to try another factory reset, re install Oxygen, or try a custom ROM of your choice. (I recommend Pure Fusion).
If you really like Oxygen, and you can't fix it, you should probably try to contact OP support about it.

Thanks, I sent an email to OnePlus support.
Same problem, OP5 bought from gearbest. it seems a defective charger (SHENZHEN HUNTKEY model).
I can't post any links but search on the official Oneplus Forum with "dash charging stop after 83-85%"
After opening a case, GearBest refunded me 30 USD.
Yes, lots of people got this problem and the cause is a bad charger. Try to charge the phone with regular charger and it probably go to 100%. If not it could be a phone problem. I got 2 dash chargers and one of them is doing that.
If you can complete the charge to 100% via USB, that tells me it's more likely a defective charging brick/cable rather than the device itself. OP support should provide a replacement for something like that.
I have exact same problem with dash charger and when i switch to any other charger it charges all the way to 100%. So i contact Honorbuy (where i bought the phone) and they will send me another dash charger.
