Hello, I'm a N8000 user. I'm facing a problem with my charging issue where my tab take a long time to charge and it takes 10 hours to get from 0-60 %. FYI, I'm using a custom rom CM 10.2. What is the main cause with the charging issue? Does it related with charging port, battery or charger itself? please help me. I'm stuck now.

Charger maybe, but most on here get a new factory cabel and that takes care of it.

Many similar thread already here & also the solutions.
But let me answer anyway.
Charging problem occurs because of one or more things:
Broken Cable
Broken Charger
Incompatible Cable
Incompatible Charger
Broken Outlet
Broken Charging Port
Broken Battery
To properly charging a N80XX we need a charger & cable that can deliver 2.1A, 5V of electrical current & voltage.
The factory default/initial charger & cable designed to deliver these requirements.
Using custom/cheap cable or cable extension can cause charging problem as it wasn't designed to deliver the required current & voltage.
Most custom cables & chargers on the market designed only to deliver 500mA(0.5A) - 1A, 5V.
Broken cable/charger can also cause it to fail in delivering 2.1A, 5V to the device.
Try another original cable/charger combination to test if one of them or both are broken.
Also try another electrical wall outlet to see if the outlet is the culprit.
For Broken Charging Port, you can change it yourself by buying the spare part & replace the broken one, but it requires high technical skills.
One mistake can cause you to ditch your device.
It's safer if you send it to a qualified/authorized service center or if it's still under warranty you can send it back to samsung.
The last possibility is extremely rare.
Broken Battery symptoms are usually different than your problem symptoms.
If the battery is broken, usually the battery life is shorter than usual and may be won't charge at all or charging time is very short.
But if this is your problem, you can't sent it back to samsung - unless the battery is factory damaged -, as you need to change the internal battery.
Try to find out which one is your real problem & fix it
REMINDER:
2.1A is producing heat so much that hurt your skin if you touch the metal part of the cable heads directly right after a long period of charging.
The heat it produce is much more intense than if you are using 500mA or 1A charger.
Poorly designed custom cable/charger can be melted by the heat & may cause explosion!!
...and.....ALWAYS SEARCH BEFORE ASKING!!
I hope this will help
I'd like to add that I was facing similar problem.
In my case, the problem was a stock charger cable.
It was not "broken" (in the meaning of totally cracked or cut cable) but it seemed that it isn't providing a stable voltage. In result, I was able to load the battery only when not using the device (plus the process was as slow as hell), coz when using it, the consumed power was higher than provided by the charger.
Meanwhile, before the problem occured, I was testing other solutions to be able to make charging cord longer than provided stock, which is only 1m. Those tests included using of the additional 2m USB-USB expansion cable which I was plugging to the plastic charger element from the one side and to the regular charging cable at the second side. Such a combination resulted in similiar results as above - then, it became obvious for me that the tablet consumes or wants to consume so high power that low-quality USB cable can't handle, and - especially if it is 2m long - it's degrading onto his way to the tablet.
Then, I am not sure if n8000, by demanding so much power, is not degrading the cable (even stock one) itself. I must say, that after that, I was using another charger cables (n8000 dedicated, one 2m second one 1.5m, both not original) which started to work significantly worse in even shorter time such as two weeks after first use. I am not a electrician or hardware specialist, I dunno if it is possible to degenerate the usb cable with the voltage such as one needed for charging the tablet, but during my over 10 years of passion within mobile devices, I have killed no more than 2 chargers IN TOTAL. N8000 killed 3 charging cables within 8 months.
For some time, I use another combination - I use a 1,5 long A/C extension cord, with a handy "8" plug at the second end. This fits into the charger "central box" after you dissolve it into two parts. Now, the voltage will not degenerate onto this 1.5m distance, as the cable of that type was designed particularly for 230V transfers, but it will still be perfectly mobile. At the second side of the box, I do not plug back the 1m stock cable (or longer not-official ones), but a cable that the Samsung provided along with an external battery, which is possible to buy here and there... It is about... 20 cm long The purpose of this was to avoid the energy lossess that occured when using longer cables and preserve the maximum possible charging rate. Since then (and about 5 months has passed) I have no further problems with charging, and the battery life seems to be much more better than I supposed it to be after over a year of really extensive usage (the only issue of above solution is that the plastic box in the middle is making really really hot, but it is not a critical problem i suppose, as since 5 months it HASN'T melted, exploded or something )
hay....i have the same problem but this tablet doesnt get charging
i think its not about charger because it gives 5v and 2A after the usb flat but in battery connector i got no current and there is just less than 1V voltage
Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
Hello,
I have a weird issue. Let me explain:
Phone: Nexus 6p
Cable: USB Type-C to Type-C google OEM
Charger 1: Original google OEM
Charger 2: CHOETECH Charger (Link)
Charger 3: Vinsic High Speed Quick Car Charger (Link)
Issue is:
Charger 1: Original Charger works great phone battery lasts like 1 and 1/2 days (one day and a half)
Charger 2: Charges well to 100% no big difference from original one but phone battery always last way less (like barely 1 day, not even 1 full day)
Charger 3: Charges well to 100% takes more time then original one and phone battery always last way less (like barely 1 day, not even 1 full day)
All chargers are used with the OEM cable and the results are observed on a period of more then 4 months. At first I thought is the new cable I used but after try with OEM cable same result, I'm not so sure anymore.
Can anyone explain what is going on? What original charger has that 3rd party chargers does not? Anyone have the same issue?
P.S. This is not about any differences in utilization of the phone when charged with 3rd party chargers. I tested this a very long period of time, this really happens.
I don't have an answer for you but I have noticed that different chargers produce different battery life results. Doesn't make since, but there's definitely a difference between chargers.
Well to prove your point : data. Engineers like data. Plot a data map.
But I haven't noticed this effect. The choetech doesn't charge at a "true" 3 amps like the oem, but very very close. Both of those chargers are very good, from my experience.
Okay I am open to any suggestions, what else could be the cause of this happening?

Not that big!
I would say, it is the perception issue and not the real one: it is hard to believe that 100% charge resulted from different chargers would last with any difference in lab conditions. Thus, I speculate, that the issue comes from different (not sure that apparent) actual usage of the phone.
The chargers don't monitor the charge level, the phone does. The phone can't tell the difference between chargers, other than what charging rates they support.
If you were charging a removable battery where the charger controlled the charge level, I could see this happening.
I'll test more and maybe come back with some results!
CHOETECH Charger has QC 2.0 this is the reason phone battery charges but not right way!
Thanks for help!
As I'm sure is the case for many of you, I have a ton of typical USB chargers around the house, which supply anywhere from 0.8A to 1.5A output. Going with the assumption that I don't care how long it takes to charge, is there any risk with using the USB C-A cable that came with my pixel and plugging into any of those old USB chargers? They should all work, right? Just as different speeds depending on the output current?
I am not an expert, but from my research into the safety of USB-A to USB-C cables, the "risk" will generally come as a result of purchasing a cheap cable that does not have the appropriate (56k) resistor. The cable that came directly from google has the appropriate resistor and is not low quality, so it will be safe to plug into any functioning USB port (either on your computer or a charger).
That being said, if you have a malfunctioning charger, or there is power surge etc., that is an "act of god" and what happens happens
You may actually be better off using these old chargers if they work correctly. The slower you charge your phone, the better it is for the longevity (years) of your battery.
Yeah, that is why I didn't care about charging speed. For plugging it in next to my bed each night, I figure slower is better. However, I just received a mini USB to USB C from Amazon, and used that to plug my pixel in last night to a 1a charger. And while the phone did say charging over USB, it didn't gain any battery overnight and instead continued to discharge until I woke up in the morning. Is anyone else seeing anything like that?
Not trying to be mean or name call but I personally think you all are crazy. Buying a $700 phone and using a cheap charger that could have the risk to break your phone. Especially if you know better. Honestly, spending the $30-$40 from a charger from Google or an approved charger is just smart for the long term and not risk losing $700. Just my 2 cents. I did the same for the car charger.
Sure, I hear your point. But honestly I know that it is better for the battery to charge slower, so I would rather use a low power charger next to my bed each night, and only use the included quick charger when I need a quick top-off.

Have to consider 2 points since there are so many inaccuracies about this subject:
1) Inadequate chargers with insufficient output cause batteries to become overheated, consequently reduce battery charging cycles. Smart batteries are not adversely affected by certified quick chargers.
2) Turbo chargers do not "top off". When a battery gets to around 80%, the appropriate charger begins its slower charging as to not overload it. Once at 100%, charging stops, and the maintenance process begins. As battery level drops to around 97.6%, trickle charging begins.
In sum, a certified, OEM-equivalent quick charger, even with higher output would not damage batteries.
The phone supports most standards however usb c and Qualcomm quick charge are not compatible and you fall back to 5v 3 amp at best. Make sure to fully insert the cable into the phone. It has to click. I've accidently not charged overnight that way.
I've got a bunch of turbo chargers that I've accumulated over the years. Using a non-[manufacturer of current phone] charger has never damaged my phone. I just bought a 10 pack of USB C adapters and popped one on every charger so I can continue using my old ones. No issues yet and I don't anticipate any.

Sure, you can use non-oem chargers. That's not the problem. Issues only potentially arise when the chargers do not provide adequate output, or their "smart" capabilities are not up to specs. I use all kinds of chargers bought at Verizon, Best Buy, etc. I also use Amazon chargers as long as they're not too far off OEM requirements. Also, people don't think about the importance of a good, thick cable.

Many will say no big deal. However, I'd say let's hear it from the horse's mouth. Here's Google engineer Benson Leung https://plus.google.com/+BensonLeung/posts/cEvVQLXhyRX. You be the judge.
Bottom line, to answer your question, no, quick charging methodology used by Samsung and Motorola is not supported by the Pixel. Your phone will charge at a slower rate. Will it damage the phone in the long run? Likely not. Well, I'll let you guys test for me.
Hello,
I have had this tabled for a while and it was always charging extremely slowly but I never took it out of the house so it wasn't a bid deal for me. However I have given it to my mother and she uses it in other ways. Anyways, the note 10.1 is the slowest charging device I have ever seen. It takes probably 48h-72h to charge it completely. I am using the original cable and power brick, I have tried ALL the outlets in my house, I have tried using the computer, I have tried using another cable (probably like 5 different ones) and other bricks (from iPads, my note 5, etc) and nothing is working. I have seen other posts regarding slow charging but none of them solve my problem.
Thank you
Thats is not normal .
I would factory reset and flash a stock rom .
Swap battery or take to a service centre .

"probably"?
You can't troubleshoot perceptions and guesses. How long does it actually take--repeatably--to charge from what percentage to what percentage? (i.e. "Went to bed, battery was at 40%, charged overnight for 7 hours and battery was at 60%.")
There are apps to check charging current (Ampere being one of them).
The fastest charge you can get is with the OEM charger in an outlet, not a PC.
Understand that this is a 7,000mAh battery without any quick charging applied to it.
Additionally, if you are using the device whilst charging it, you aren't really charging it since the drain is about the same as the charge; you'll effectively neither charge nor discharge.
Finally, check for battery-draining apps; you might not have a charging problem but an app-drain problem.

The time varies, but it is between 2 and 3 days to charge from 0, never less.
I do use the OEM charger and cable and an outlet.
I do understand that but 2 days seems a bit of a stretch, don't you think?
I am definitely not using it while charging, because it's impossible. It just doesn't charge fast enough to be able to use it. It drains quicker than it charges.
I highly doubt that, I only have YouTube and Chrome installed on it.
Above 6 hours with stock rom and charger is abnormal .
Usual replies .
One cable
Two charger
Three battery or connections .
Four USB port
Five motherboard .

Yeah, 2 days isn't right. It also shouldn't be discharging faster than charging, especially with the OEM charger.
I leave mine plugged into my PC (only 500mA max current) with the screen on (about medium brightness, mostly black screen, which is most power-friendly for OLED) using LectureNotes all day and it will neither charge nor discharge (technically, it's charging at the same rate it is discharging); the percentage doesn't move.
What does Ampere report?
Do you have another charger you could try? any 5V and at least 2A would work.
Also, ensure your cable isn't intermittently open (a break in the cable, temporarily disconnecting the charger).
If the cable and charger are good, then the battery would be the next likely culprit, followed by the charging circuit.
Finally, ensure heat isn't an issue (is it in a case? remove it).
Mine was messed up but I concluded it was the port and cable. I got a new cable and then replaced the charging port and viola. Charge time went from 8 hours back to the usual 3-4
