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?

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]

Charging Issues

Okay.
So like 2 months back, all was very well, my OP2 charged in around 1.5-2 hours. I was using the official OnePlus Charger and OnePlus Type C cable. After like a week the Type C cable stopped charging so i bought a new Type C cable, which worked great and charged my fone quickly. At that time, I used to check the charging with the Ampere App, and it showed normally 1100 mah charging.
Gradually over time, the charging speed started to slow down and then it came to the point when my phone was charging in 4-5 hours. So i again changed the wire, but no use as its the same i.e slow charging. (Checked with Ampere it is constantly showing 500-600 mah)
Since the wire is new and the OnePlus adapter is charging my phone, i do not suspect that the OP charger is at fault.
I am currently on Resurrection Remix 7.8.2. ( But this is also happening when i flashed OOS)
Plus a meagre 2.5 hours Screen On Time and yester overnight it drained 44% in 6 hours.
I have no idea whats going on.
ANY SUGESSTIONS AS TO WHAT I SHOULD DO?

Make sure you're using a good cable. Not some cheap knockoff.

Yeah. Dnt wry. The cable is of good quality and not a knockoff.. any other suggesstions?

Maybe its your battery then

It's all one plus work.
I can confirm this as well. Phone started taking excess charging times. Around 6 hours for 80%. This cannot be a battery issue. Battery degrades linearly. It's surely scam by the scum company one plus providing a time bomb style update to make old one plus 2 unusable. So many reports of op2 slow charging. Same issue reported in a previous post. He also mentioned that turning off phone and charging takes usual 1-2 hours time. Check if that's the case with you as well.

I haven't tried yet changing the ROM but as per other users changing kernel and roms doesn't matter. It will still be slow like hell. The strange part is this all started in may for all. Too fishy to be a coincidence.

I am getting good charging times.

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.

Have you tried to change the charging cable. I had the same issue and changed the charging cable. It worked for me.

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.

Op5 won't charge past 70%

The past couple months I have had some charging issues with my phone. The first few times it just didn't want to recognize the charger or would only slow charge. A couple times cleaning the port helped. Then it seemed like the cord might be the problem so I ordered a new OEM one. The problem has gotten worse and happens the same with the brand new charger.
The last few days it will fast charge to 70% and then stop charging altogether. I can't get it to take any more than 70%. I had the accubattery app which had a feature to stop the charging at a preset value to prevent wear of the battery. I only used this for a little bit and turned it off. Then I uninstalled the app in case a glitch was causing it to keep stopping the charge.
I have a new OEM battery ready to install if the battery is indeed faulty but even starting at 70% I can't kill the phone in a day so I'm not rushing to replace the battery yet. I'm just not sure that is the problem.
The phone is not rooted and is completely stock. It hasn't been wiped or anything since I bought it new over a year ago. Anyone have any ideas?

Update: I powered off the phone when it was refusing to charge at all and it was down to 56 percent. While powered off it charged all the way up to 100% no problem and since doing that it will charge without problems. Seems like this fixed it.

Update: the problem is still there. Still not charging above 70% while turned on. Not sure if the battery is failing or if it's a software issue.

Does anyone know of any other forums people might be discussing issues with the OnePlus 5? This forum is looking quiet these days and/or people aren't having a lot of hardware issues with this phone (hopefully).

The op5 forum isn't quiet. If nobody has an idea or any possible solution for you, you won't receive an answer. Seems you're the only one who has this sort of problem.
If you have warranty, just claim it. That's the easier way. Cause when it's the logic board or parts of it, it can be expensive.

It's already over a year old so no more warranty. I'm just going to try replacing the battery when I get a chance. If that doesn't work I'll try a new charging port (already tried a new charger).

Have you tried using the Ampere app? It does not make any magic, but it can give you and idea of what the problem may be.

Yes I installed it the other day and discovered when I was plugged in above 70% it was actually charging but very slowly. But this isn't always the case because when I first discovered the problem I kept waking up with a phone at 70% that had been plugged in all night.
I'm not sure how long ago this started because I typically try to charge it in the morning after my alarm goes off since dash charging is so fast. Eventually I noticed it never getting above 70% so I plugged it in overnight and still didn't get over 70%.
Accubattery says my battery is now 82% healthy. Despite not being able to charge above 70 I can still get a heavy days usage or a couple easy days. So maybe the lost health in my battery came completely off the top of the displayed percentage of my battery?
Occasionally it seemed like my phone wouldn't charge at all no matter what the percentage so the problem could be worse, but I may also be dealing with a worn out 1 year old charger cable and a new one I got a month ago that is defective because when I couldn't charge at all with the new one the old one charged fine. So I'm still trying to figure this out.
Sent from my ONEPLUS A5000 using Tapatalk

i am facing the same issue, i keep plugging the charger in and out till it works ... don't know why

Now that I've gone back to the original charger it seems to be making it to 100% every time and no longer seems to stop at 70 but if I move the phone a little while plugged in it sometimes stops dash charging and starts slow charging. Before when I heard it stop charging and start charging again randomly while I was in bed (it makes that little sound when dash charging starts) it was sitting on the floor unmoved.
So I think my possibilities are 1) 2 bad chargers
2) 1 bad charger and a bad charging port
3) bad charging port
4) bad battery + 1 or more bad chargers.
Or any other combinations of those problems. I think I'm dealing with 2 issues and that's why I can't figure it out.
