Fast charging issue

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!

The o2 shop swapped my charger and usb cable and its all good now [emoji3]

Faulty charger?

Ok I just receive my Axon 7 Wednesday. After draining, I charged it with included charger and cable. Quick charge is working but it keeps on disconnect/connect cycle for every 5-15 secs. It's annoying as hell since screen goes on and off with sound! I tried it charging it thru pc and it works fine. Also, the charger have a buzzing sound (coil whine). It sounds like its going to explode so I never tried to charge it more than 10 minutes on 2 tries. Luckily, my sister note 7 quick charge works fine with it. So, is the included charger faulty? Should I contact zte for this?

I would contact ZTE - my charger is quiet. You sure the buzzing sound waqsn't from your sister's note 7?

Same issue here, except oddly it only starts to connect/disconnect from the included charger if I try to turn the screen on while it's charging. Once I put it back in standby it stops. For now i'm using an older non-Quickcharge Samsung charger and it never happens with that one. I'm within my exchange period though, considering exchanging the whole thing rather than taking a chance that it isn't the charger and then ending up with a refurb from ZTE because my 15 days is up to exchange in store.
It also makes some sound, but it's very quiet.

I'm having exactly the same issue. I bought one, had this problem, exchanged for another, same problem. Also, I've tried a couple of different chargers and cables and it's always the same. I've noted that if I charge while it's off, there's absolutely no issue, so it makes me believe that it's just a software bug.

hi,is that A2017U or A2017G?

This started happening to me. Except I can't charge neither with the included charger or my s7 edge charger. Going to have to send it to ZTE. Anyone gone through the exchange? Just got the phone 4 days ago

Just got mine a few days ago. With any charger and cable, ZTE or otherwise, it's taking 15 hours to charge from 0. Have to jiggle the cable to keep it connected. ZTE tells me bad charge port or battery. Won't enter Quick Charge. Shame it has to go back. Nice phone otherwise.

Do you get QC from the computer. I tried plugging into USB 3 port on mine. Still estimated 10 hours from 40%. :crying:

The charger come with phone do not charge my phone. the led come ON, sait it is charging but it stays 0% for hours.
I try to charge with my old quick charge 2, It go from 0 to 77% in 7 hours.

Sounds like bad battery. I'd reach out to Le Eco for replacement.

FYI it is really hard on your battery if you continually drain it significantly (< 20% or so). I used to do the same as you, but read several articles showing how it reduces the life of the battery. Now I usually charge around 30%. Once a month I'll let it go to 0 to make sure that it is calibrated.
You should stop draining it completely.
I can find the links discussing this if you don't believe me.

Hi,
I went to my friend house and used his LG G5 charger quick charger 3. It work great. Passing from 75% to 100% in 30min. So, I guess it was my Original wall charger that has issue.
Thank a lot for you guys help.
and @slgooding, thank I will that info in mind

The leeco cable is not good at all so maybe the problem is the cable

The LeEco charger that came with my LP3 also died after using it for a couple of months. I ended up just getting another QC charger from amazon. Hopefully this is not an indication of the reliability of the phone itself.

I bought these USB-C cables (5-pack) from Amazon, they are really sturdy.
https://www.amazon.com/AUKEY-USB-C-.../B01B634WNK/ref=sr_1_1?ie=UTF8&qid=1488118508
It has a long one good for wall charger, a very short one good for PC connection, and the middle ones for car, office, etc.

Hope this is just one of those bad ones, not the quality of the phone, I gave up my One Plus 3T for this one because of the price and and this phone is like a beast=)

21s update maybe?
After 21s update mine stop charging normally. Only after I reboot the cellphone it charge again. Same with different chargers and this happen immediately after the update. In 20s was working normally.

I tried with a couple aukey chargers with QC 3.0 and no way to make it work. My temporal solution is reboot, by the way I send all my founds to LeEco, I'm waiting for a official statement.

Same problem here, after latest system update the phone will not charge when plugged into USB. A reboot will allow it to charge. Anyone having this problem should report it with the Feedback app to hopefully get exposure, this is pretty big deal on stock.

Hi,
In my case, I confirm that the problem came from cable.

2 month old ZTE AXON 7 won't quick charge anymore.

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.

One Plus 2 battery drain

Hello,
I am using One Plus 2 for a few years already. Lately I started suffering because of battery drain and long time charging. Problem is quite serious because while charging and using phone battery % is getting down. It takes whole night to charge it to 100% and in the midday I have 20% left.
I tried to use different chargers and cables. Didn't help.
Today I changed battery to new one. Didn't help.
Wiped out unofficial rom, installed official stock one. No addtional apps installed. Didn't help.
I am charging it with charge monitor app and while on AC charging I get very unstable charging graph. I need to turn off screen and leave phone untouched to charge it.
https: //zapodaj.net/21c02b80b986a.png.html
Where else to look for a reason?

Usually LTE connection drain the battery. Try disable it and try for few hours.

I tried to charge it with airplane mode. Didn't help neither.

Hi
Did you resolve your issue? I have same situation but I think that happened after when I do update Oxygen, now charger my battery is really slow and drain battery really quick. I can just leave, not touched my OP2 for all day and the battery after 8hrs got 30%. I buy original battery and still nothing change for better.

Another problem is with a cable because original cables for OP2 can't buy anywhere right now, the company OnePlus has stopped production this cable for this device so I buy original cable Dash Charger from site oneplus.net

Three possibilities (at least):
* The charger is not working
* The cable is not working
* The battery is failing
Solutions for the first two are more obvious than the last one. Pick up a new or working used charger/cable. But the battery is a little dicier. And frankly, it is also more likely the cause for this than a bad cable or charger (esp. charger). But re the battery... No direct sales from Oneplus are available except via an official Oneplus repair job, which requires you sending your phone to them and them replacing the battery. Obnoxious, eh?!
The unofficial route? This is frowned on by many here, but not me. Buy a cheap ebay battery for the oneplus 2. Look for one that at least promises the battery's power matches the phone's specs. I bought one for $12 from an American seller (because I wanted a bit more accountability if it didn't work). They do work. They also take a while to start reporting their voltages and charges correctly, and must be charged / discharged completely a few times before things start getting accurate.
That's no official answer... just one guy's experience. Hope it helps.
