Hey everyone,
Before my Transformer arrived at my door-step...I started reading around a bit more about spare chargers and such - and came across a few threads that people had had trouble charging their TF101 because the AC Adaptor was fried/dead/whatever.
I own the B60 version and all seemed to be going well until late today. I plugged in my charger as per usual...and no charging icon. I did a few plug ins/outs and swapping the polarity of the plug to no avail. I also tried an iPad 10W charger and that did nothing; proving to me that only the supplied charger or a 12V molex rail can charge the thing.
I then thought of any changes I had done to my TF101 over the course of the last 24 hours. I remembered. I had installed Clemsyn's kernel v9 on the Revolver 2.5 ROM. So...I thought about reverting to Netformer 1.6 kernel I was using before.
After flashing, it started to charge again. (Note: I did reboot the TF101 a few times before this to see if it was a Honeycomb issue).
This is a theory anyway....if the chargers are failing on stock ROMs and kernels...well that's ASUS' fault.
Hoped I helped anyone.
i don't know about this. I got a b60 also. The charger didn't work the first night I got the transformer. Stock rrom stock everything. I played around with the charger and it worked again. Now sometimes it works, sometimes it doesn't. Im on custom rom now and its still the same.

I was completely stock when my charger just stopped charging both the dock and the tablet. A few days later it started charging only the tablet and only doing that occasionally. It never did charge the dock again. It was the impetus I needed to finally RMA everything back to Asus for which I am waiting its return. It seems to me that this charger just can not be trusted and that is a big problem with a proprietary charger!

How many chargers have you owned, and how many of them have died? If it's a sample size of one, it's pretty-much meaningless. You only hear complaints from people who have a problem, after all.
Personally, I've used three chargers (mine, my wife's, my fathers) with three tablets and three docks, and none have had problems as yet (several months).
I have a B4O TF (fantastic BTW) and my charger died ...stock rom etc.
sent to asus...week later they still can't find my RMA (and I thought Dells customer service was bad)
I had already bought a charger for spare so I can wait
I bought a 5mm DC Female Barrel to USB Female cable - EBAY $2.99 and I'm always looking at chargers for it when I see one... Bought a I home 120V AC to 15VDC adapter at goodwill this weekend for 1.99 total cost of my new charger (others gonna stay in the drawer) 5 bucks and some change
find the Barrel to usb connector link and info about it in DevCake's thread here

i had the same problem with my charger month back when i got my pad. i called asus. it is a known problem. they sent me a new /replcemnt part for the charger. no hassles . ive been fine since
I experienced this same thing last night. I had flashed to Clemsyn's kernel Elite v12a kernel. I did a reboot however and charging resumed. I was having a hard time connecting to the computer as well. Perhaps, the kernel or settings still thought that the Transformer was connected to a PC because it will not charge from a PC unless the screen is off. There must be some script that is being interfered with here. Your theory may have some traction.
I was rooted when mine decided it didn't want to charge anymore, I had only had it for 5 weeks. I unrooted and even back to stock it still didn't want to charge. I sent it back to them and they fixed it after a week. Everything's been good so far.
My charger was working intermittently and I was near the point of returning the TF w/ dock or buying another charger. Then I tried running the charger thru a car power converter in my car and it seems that did the trick. Now it charges everytime, its worth the try.

okay so im not the only person here. my charger just stop charging yesterder. never rooted, always stock rom. i did factory reset, and still no good. now it only charges very slow, no charging icon showed. the cable is good, i can still connect to laptop.
The real question is: Is it the pad or the adapter? Because if it's the pad, that sucks big-time, if it's the adapter it is irritating but not a real problem, you could charge it via USB on your laptop/PC
I finally contacted Asus regarding to the faulty charger. And they told me to return the whole thing to the my retailer, because im still within the 30 day return period.

Charging via a PC is very limited. It will be very slow if it works at all. The charger provides higher voltage (15 vs 5) and higher current (1.2 vs. 0.5 amps). The charger and pad also expect the current on non standard pins association with USB 3 connectors.

Gotta be the adapter. I tried everything to get it working again, I noticed that when the screen was off, and I plugged it in, nothing would happen. But If I plugged it in to a smaller charge adapter, it would show the screen (as if something were connected), but not charge. So I tried my friends charger and it instantly started charging. However, After I charged it, I went back to my old charger, and it worked again. WEIRD! I have a backup adapter now just in case it happens again. Same thing happen in the past, It wouldnt charge (and I didnt have my friends), so I let it die, and charged it with my smaller adapter (which took like 1-2 hours to get 7%). Then I plugged it in again to my old adapter, and it charged it. It's almost like the charger reads it as full, and wont allow it to charge anymore. Then when some other adapter start charging, then it realizes it does need battery. No idea. Just my 2 cents.
Clemson Blades v.17 fixed it for me
Charging required a reboot after a certain amount of uptime. But, I also use Battery Monitor Widget's circle battery status icon. What was wierd is that sometimes the ASUS battery icon wouldn't show charging, but the circle battery status icon would.
Anyway, everything works for me now with Clemson Blades v.17. He specifically added in usb forced charging with v.17.
I saw the same problem with both ac adapter and computer's usb, but it was fine for a while after reboot but would stop working again after a while.

If anyone did a search, you would know that this is a common problem.
The trick is to unplug it for 5 or so minutes and it'll work again. Also, the writing on the plug should be facing up.
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 !

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
Hi guys,
I recently brought a new Note 4 two weeks ago and its awesome, but 2 times this week now I've stuck the phone on charge to get a boost & the fast charge facility has not kicked in.. meaning its only charged about 20% in 30minutes.
If I restart the Note it seems to correct itself but it is a bit frustrating that the phone is less than a month old and 1 of its main selling points isn't working properly.
I have got a sm-n910f running Lollipop 5.0.1
My phones not rooted and I usually clear open apps before sticking the phone on charge.
Fast charge is toggled on. Can anyone give me any suggestions to what might fix this?
I put this query into the battery thread this morning but didnt get a response, so apologies for clogging up the forum but I am hopeful that some genius on Xda can give me some help here [emoji3]
Thanks for your help
Fast chargin is working only till 50% If you are more than 50, then it is charging with normal speed.
Thanks @Matin.salat I know this. When put my phone on charge at 15% and went to check it 20-25 minutes later it had only crept up 9% to 24%
do you get the "adaptive fast charger" (or something like that) notification when you plug it in? are you using the supplied cable? power only cables do not work with quick charge; needs to be data+power.
AFAIK Fast Adaptive charging only works if you have the specific adapter (charging block) that is capable of it. Are you using the original charger that came with the Note 4?
Below is a link to the part on samsung's website;

Yep using the correct charger and usb cable that comes with it. I chucked my phone on charge at 14% at 17:45 today. Went to grab my phone at 20:00 and its only at 43% charged.
I'll be taking it back and replacing it tomorrow or sunday.. I must have a faulty handset!!!

Hey.. I am using a SM-M910C. I had a similar problem just like you. My device is just 4 months old. Fast Charging used to work properly until a week back suddenly I noticed that it wasnt charging fast. Just like you mentioned, it was charging extremely slow. I checked everything to find out whether the problem was with the phone, power brick or cable. I borrowed my friends cable and tried it on and voila it was working fine. It was showing fast charger connected in notifications. So then I remember that, I had used the same charger and cable to charge my Power Bank before that. And I clearly remember the cable being hot at the time when I removed it. So figured that the cable got burnt off or something. Because the cable needs to have a particular resistance in order to support fast charging. Went and bought a new authentic cable and now fast charging is working as it used to. Never gonna charge the power bank with it anymore.
Hope this helps. Cheers!

fast charging not working
Hi we have similar issues, my Note 4 is almost for months old in my hands and I have no issues with fast charger before..it was just happened after I updated my Android version to 5.1.1 lollipop..and now this happened I started charge my phone at 6:47 pm and finished 9:15 do you think its normal ? sounds stange ! normally before Its finished just only 90 minutes..hope some one can help my problem and fix it.. thank you
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.
Does this phone require a specific cable and or power block/car charger to charge? Im using my regular stuff that I use on my s8 pixel 2 xl and at first it said slow charging. Now it doesn't charge at all. I tried using a portable battery pack still nothing. Works fine on my pixel 2 xl. Not sure if it's defective or requires a specific charge like the oneplus 5 did.
Well this is weird after trying to reboot it got stuck in shuting down screen so I had to hard reset and now it charges.
No special charger needed. I use a Pixel charger and a Samsung Fast charger, and they both work fine.

I have the same problem (white Sprint unit) with car charger fast charging works with other phones but not with ph1 and for couple of hours couldn't charge at all only after reboot start to charge again
Mine sometimes bounces back from rapid to show charge but I'm sure it's always rapid charging. Regardless of what state of charging is showing, my drive home from work always almost tops up my phone to 100%.
I just charged mine over night and it's at 92 percent when I checked it read slow charging 5 hours till full. I unplugged it plugged it back in same thing slow charging this is weird.

I owned this phone 3 times and they all did the same thing. Its the reason why I returned the first 2. It would work for a month with no issues and then I will have a issue for a day or a week and then it goes back to normal. I normally use a 3rd party charger that I never had a issue with. It might be it doesn't play well with other chargers. Reminds me of the Amazon Fire phone, it did the same thing. It charges fine with the original charger but acts up when you charge it with a 3rd party charger.

I use the charger for my Huawei Mate 9 at work, and the PH-1 at home. The mate 9 works for rapid charge just fine.
