Fast charging

Is there a set of rules that it follows before fast charging works? I'm not sure if it's that or my phone or charger is bad..
Seem like I can only get it working 30% of the time. I would have to unplug and plug in multiple times before the notification pops up saying fast charging.
I tried multi USB cables and pushed it all the way in the charger.

I haven't managed to look at kernel source yet (not yet released), but maybe charge type is not only dependant on charging source type, but current battery level. ie top off charging. Just guessing for the moment............

I have the same issue. The quick charging notification never pops up the first time. If I unplug the cable and plug it back in, then it's fine. I'm using the wall plug and cable provided by Samsung.

Don't know. I've only charged my phone 2x, but fast charging popped up both times.

Actually no, I bought the T-Mobile version. I doubt it matters but it's the 64gb model. It sucks that you exchanged yours and have the same issue.

I picked up the AT&T model yesterday. Plugged into my car charger, 2amp, works fine. Got home and plugged in before bed with samsung supplied charger, showed fast charging. Passed out and woke up to 40% battery this morning. Turns out it will connect fast charge (ONLY if i use the supplied brick AND cable), but cuts out after about 5 mins! If i use the 9v brick with a random cable, it will just say cable charging, but seems to be decently speedy and won't stop charging. Seeing how crawldit replaced his and has the same issue leads me to think Samsung really was hoping people would get the wireless pad. Hopefully its a minor software update/patch needed. Phone is a freakin winner on all other aspects. Battery life appears to be better than the note 4 even with a slightly lower mah.

Definitely a software issue IMHO, from the sound of it. Also, on my VZW 32gig I do not have this issue. Every time I plug it in (to the supplied charger) it fast-charged. Cant say if it gives the message every time though, but I know it fast-charges because its never on that charger more than 15-30 minutes and the charge jumps massively. But even on a normal charger it still charges fairly quickly.

Well... turns out my brick was bad, used the one from my Note 4 with the new note 5 cable and it works like a charm. I'd recommend checking out a new brick.

Glad you got it figured out. Mine works fine now as well. I don't know if everything was overly stiff from being brand new, but after a day or two the fast charge pops up the first time every time now.

Fast charge problems

Hey guys anyone experiencing problems with fast charging not working, tried using the moto fast charge cable and charger and still nothing. Seems. Like after the Roger update it only works like 20 percent of the time

I have the same problem after I updated my note 5. I'm just waiting for Google to push another update to fix their f*#$ up.

Yes, works most of the time (90% of the time). Using all equipment that came with phone. Fast charging hasn't worked probably 4 times over the past month. Will unplug/plug back in a few times then magically starts working.

no issues on Rogers here

So I went to the AT&T place to see what the problem was. The guy there switched the wall adapter that went with my charger to a newer one of the same model, and my fast charging capabilities came back. The fix was simple. The problem was in my Travel Adapter.

I do not know if that will help you but to be sure if fast charging is working or not, you need to plug it in and turn it off. Then, you should have 3 green LED lights flashing. If only one is flashing, then it is normal charge. If 3 are flashing, then this is the fast charging.

Fast Charging not working

Hi all,
I've looked through several threads before making this one, but couldn't find a solution to my problem. I've got a Tmobile 32GB Note 5 that never had any problems with fast charging and as of today, it no longer fast charges. I've got several OEM fast charger adapters/cables along with the fast wireless charger and none of them are fast charging my phone. I've cleared the cache partition, done a factory reset and nothing seems to be working. I've also made sure that the option to fast charge are turned on in the battery section and no dice. It used to display a toggle to fast wireless charge in the battery settings as well, but that option doesn't appear anymore.
One other interesting thing is that whenever I'd connect the cable I'd get the USB message which never appeared before. Even when I did restarts, the USB message would always appear in the notification despite no USB cable being plugged in.
I'm very frustrated about this as I've been trying to work what's causing this problem and I've tried most tips/solutions, but having no luck.
Any help would be appreciated and thank you.

hi,
Firstly, i dont think i could give you a positive
answer to your issue, but maybe some pointers
to consider.....?
Ok, Secondly i found that fast charging does not
always have a positive effect on your battery. eg battery life
Even more frustrating when your battery is sealed
and if you want to ever change the battery , you have to pay Samsung /service provider to do the job.!
Thirdly, i had similar issues(like you) with fast charging my Note 4 and Note5.
My Note5 also suddenly stopped fast charging and
would only "cable charge " (re Notifications bar)
I tried all sorts of settings combination, nothing worked. Like you i became frustrated because I could not sortt issue out.
A few months afterwards i swapped my usb power cord around and used my old Note 4 usb cord... suddenly fast charging, was back?
(Why i dont know, as i did try out different combinations.... then.)
Ever since i started to take note/ (info) of the effects on battery fast charging. eg Forum members experience and remarks, my own personal experiences Web articles//opinions etc.
Came to conclusions fast charging , will /could shorten you phone battery life eventually? Not good.
I think even Samsung realizes it (my opinion)
So now i have my fast charging back, i mostly cable charge.!
Good luck

note 5 - USB not recognised and it never fast charge

Hello I have a note 5 - SM-N920C on stock M 6.0.1
about two months the phone stop fast charging and doesn't get recognised by the pc
the thing I tried :-
* try different USB cables ( 2 came with the phone - 2 new once )
* factory rest ( twice with wpie chashe )
* change the charger
I wanted to test other stock Roms but I can't get it recognised by odin .
and I have 2 note 5 all the cables work fine on the other one .
​

I seem to have same issue here.

I have the Note 5 from tmo(SM-N920T)
Baseband - N920TUVU2DPD1
Stock - 6.0.1
You have the exact same issues i've had. I also had issues where when i would have the phone plugged in ( to the wall adapter ) and rebooted it, it would think its a media device like a computer where it could share files and stuff... Also take like 5 hours to charge from 20%
Here I'll make this fix SUPER EASY..
1. Download Package Disabler PRO - I dont think it has to be the pro version but i bought it a long time ago
2. Search for 'power'
3. Disable 'com.sec.app.TransmitPowerService''
4. Reboot
I would add screenshots but as i dont have 10 posts im unable to post screenshots or links to the app in the playstore.

The wife's phone started this Saturday after updating. Also, hers beeps and has the charging blue wave as if she plugged the cable in. While actually charging, it disconnects and starts charging constantly.

The beep and blue wave is normal. The charging and no charging sounds like a faulty cord that's not making good connection

The beep and blue wave happens when she is not plugged in. Phone just sitting there not being charged or touched. We thought at first it was a bad cable, but we've tried several. Even does it on the wireless pad. Therefore I'm not sure it's the port. I think it's software related.

Have you tried safe mode?
Just a warning safe mode reset my wall paper and logged me out of some apps.

Did try safe mode and a factory reset. Sprint store I brought it to tried several cables and another factory reset with no luck so they ordered her a replacement. They weren't too interested in figuring it out. In fact, 3 other people came in with various issues and were just given the number to make an insurance claim without even looking at the phone.

I disabled that apk abd it detects all my fast chargers as fast ones. Where it didn't. If i re-enable it it stops workin

might be hardware issue, Try Wireless charger and see if it charges fast. if it charges good with wireless charger then you have to change you CHARGING PORT.

Had the same exact issue on a refurbished unit . Old note didn't do it, but had to exchange it due to adhesive glue coming up in upper left corner. I did multiple resets and finally went with the option of fresh install as not to import back my apps. It hasn't replicated our issue in the last few hours. I am hoping that takes care of it.
Did you by chance get a random gear VR screen prompting you to download the app and what not? I did and read others had the same issue and only way to get this to stop is to download it and then create an account, reboot and viola it solved it.
Stuff is crazy, love the phone but have had more issues with it over even El cheapo phones....

I got similar problem... now after 10 days I just can not go with this.
my youtube problem.
https://youtu.be/payi2IuJhdI
My NOTE 5 is thinking that is charging all the time. It drives me crazy.
With the USB cable it charges 1 time out of 20 and on a random day. I had to charge it via wireless. It wakes up all the time and can not use UBS.
Strange part is, that I can use my USB micro stick with my root and custom ROM. But that is it. No ODIN, no tranfer files.......
Did everything except change the USB port (it is on it's way). ( that will be my last resort)
ANY THOUGHTS.
I have a feeling that water damage was somewhere in there. (been driving with my bike on a rainy day and it looks like it got a little wet in my upper front pocket.

mine recognises fast charge very randomly. before it happened rarely but now it never shows fast charging with the original cable. the only thing that helped me was ordering a third party cable and using the original ac plug. let me know if that helps to any of you guys!

Ugh. N920a mine started this in March after having it maybe 3months. I called att and told them to send me a new one the other day. Unit arrived this morning. My opinion is its a bad USB port. This imho is the weakest link in Samsung devices-- this POS antiquated USB crap.
The thing would cycle CHARGING -- DISCONNECT, over and over. Wiggling the cord would affect the condition. Fast charge happened 1 out of 20 attempts.
I'll let you know how long the new unit lasts-- my most recent purchase is a wireless charger because, as stated this ***t is bound to happen again.

Unbelievable. My phone was totally fu**d. Than I sad I will fix it my self, so I bought the USB board and waited to get it. In the mean time I used it as normally, just wireless charging and that's it.
But after two weeks, the phone was getting a little better, not fixed, but due to custom ROM and a few tweaks, it did not turn on itself all the time.
But after I played quite a few games, (hitman) the phone did heat up all the time, and that my friends FIXed my problem. NOW the phone works as before the moister get to it.
I have my NOTE 5 back, yee.
SO when you have moister problem - play games.

Hey guys,
I had this exact problem - no more fast charging, no USB OTG or recognized by computer after
upgrade to Marshmallow. Tried multiple cords, different computers (Mac, and Windows), etc.
I sent it in for repair to Samsung and they 'fixed' it and are in the process of shipping it back
I put 'fix' in quotes because the repair tracking says it was solved, but I haven't received it back yet to
test. It should be coming in tomorrow.

Quick charge and USB issues have been fixed! IF you're still under warranty, I'd highly recommend sending it in.

Fast charging is gone

Anyone know what I have to do to get fast charging back? I have the option enabled in settings. The cord is good, my wife's phone fast charges just fine with it. I've soft reset the phone, cleared cache, and just about any other option I could find on the web. So weird cuz it was working fine not too long ago but just noticed now that I can't get it to work.

Try cleaning the usb port on your phone. i had the same problem, just cleaned it out with air.

Thanks but been tried that. I work in Audio/video so that was one of the first things I tried.

Are you able to mount the phone as storage on a computer, or able to access a USB with the OTG adapter? The charge port on this phone isn't the most robust and a few people have had problems with then failing.

No issues with any other stuff except fast charging. The phone charges fine but just say fast charging and takes forever. It's so weird cuz in my car my phone would barely charge when hooked up to USB in console, but then soon as I lost fast charging at home it started fast charging in the car. I just don't get it

Well luckily normal charging and USB still works so it's not the worst. At least your battery will last a little longer now?

My advice would be install an app like accubattery
https://play.google.com/store/apps/details?id=com.digibites.accubattery
It will show current when charging.
Fast charging being displayed by Android only seems to indicate fast charging is enabled rather than actually occurring.
I find when fast charging is occurring with standard Samsung charger, but not original cable it will show approximately 2800 mA.
It did seem to be below this rate a few months ago when ambient temperatures were higher and battery temp got above 36 °C
I also bought an unbranded charger cable that has an led that illuminates bright when high current charging and dimmer when charging at lower rates.

Probably defective . I've read issues on here about fast charging no longer working and it had to be repaired by samsung.

Ive had this problem with all my samsung phones since galaxy s8. I dont know why after some months the phone loses the ability to fast charge (it happened to my s8, note 8 and currently note 9)

I finally replaced the usb-c port
I had the issue that fast charging was gone and it charged very slow sometimes. I did many searches and did everything I could do. none changed anything. finally I went to Samsung and they replaced the port.

It was. Now I am a bit skeptical about this USB-C port thing. I take good care of my gears. Especially this one that cost me an arm and a leg. I want to do a survey if all the manufacturers' type-c port is prone to get damaged like this easy!

I would take your device to a Samsung Service Centre and let them take a look at it.
