Wont quick charge/fast charge not working

Phone is not rooted or anything, fast charging just stopped working out of nowhere no idea how to fix it so i tried resetting phone, and that didn't work either i have no idea whats wrong?
I have the 4gb model and using the charging that came with it along with other qualcom quick charge chargers and none of them work

Not to point out the obvious, but quick charge only works for a certain battery percentage. It is 0% to 50%, I think? After that it reverts to normal charging.

Same problem
I have the same problem on my Asus Zenfone 2 (2GB version). It used to quick charge perfectly fine with a Samsung adaptive charger but now it's only charging normally (5V 1.1A). I tried different cables with no joy.
I bought a USB device that connects between the charger and the USB cable to check the voltages on D+ and D-. Apparently the phone is asking for 12V instead 9V (0.66V on both D+ and D- instead 3.3V on D+ and 0.66V on D-).
I can only guess this is a software issue from an update?
I ordered an external battery pack from Aukey that offers Quick Charge 2.0. This one can offer 12V too. If that works I'll come back with an update.

No, my phone will show quick charge at any battery percentage. It doesn't come out of quick charge until fully charged.

Post a photo of your screen showing that you're still on quick charge after 70-80%?
I know it stops at a certain point. When I check my phone after a 45 minutes or so of charging when its nearly full, I don't see the quick charge icon anymore nor does it say "Quick Charging", only "Charging".

Well, obviously I don't know what I"m talking about. I thought the "+" in the battery indicator meant it was on quick charge.
When plugged into my quick charger (I have two different ones by different manufacturers) it always shows the "+" in the battery indicator.
I don't know how to tell it's in quick charge mode except by the message on the lock screen. And you are right, it goes from "quick charging" to "charging" about the power level you indicated. Hadn't really noticed before. Now I'm a little smarter

I also have the + sign from 1% to 99% using original charger.
It does get less hot after 70% im sure quick charge slow down or off at this point

same here..

Same here - sometimes the quick charges works (from 0%-80%), sometimes it stops at 20% and I notice too late the phone has not been fully charged All this with the Asus original quick charger ...
Normal charging works always, not a single problem ..
I guess this is a software issue ...

not really, my zenfone 2 used to fast charge even at 82% and charge to 100% after 10 mins, but now it's at 49% and says fast charging but the completion time shows 3 hours until full. I dunno why

I've been having similar issues in recent months, but I'm thinking the USB cable may be worn out - usually when it shows it is charging in regular mode, if I unplug the cable and put back in the + appears. Also a couple of times it has claimed I am using an unsupported charger (it is the same ASUS fast charger out of box..), which is also resolved by unplugging and replugging things.
However if the phone won't fast charge, won't detect OTG drives and PC can't detect the phone then a part of the chipset is probably toast.

anyone have a slow charging ?

im running ARHD 12.0 [Android 5.1] and facing 340ma charging, around 3-4 hr until full
anyone have the same problem ?
before i use this rom (running stock rom) i also have this problem.

I feel like it takes the phone a little to "set up." When I first got the phone it took forever to charge, now it does it fine within 2-3 hours. I plug it in and I see it charges decently fast. When I first got the phone it was really bad at charging though, I really was about to send it back.

Make sure you use a genuine charger. htc or samsung chargers seem to work fine.
An under powered charger will cause the phone to whinge incessantly about low charging power, refuse to swutch off the screen and waste power like its going out of fashion.
Htc logic.. Something not to be desired..
Sent from a stolen (and crap) HTC M9

Old thread I know but most relevant I could quickly find.
Using standard charger included with M9 I could charge from 0 to full in about an hour and a half to 2 hours maximum. Lately, it now is taking 9 to 13 hours with the same charger and cable. Have swapped out cable, no improvement.
On stock, no root, TMO, firmware 2.11.531.19. Charging with unit off, in recovery or bootloader makes no difference.
Any ideas?

Turn the device off and charge it. If it charges in the correct amount of time then you can assume you charger is good but the phone is demanding too much power.

I had problems with charging recently. Very obvious fluctuations in charging and not charging to 100%. The problem was lint in the micro USB. Search YouTube videos on how to safely clean them. It has to be worth trying.

Depends, I've had bum adapters before. Had the same issue with my old Note 3 using it's included adapter. I switched to a different one I had (an LG one) and it charged fine afterwards.

My issues were solved by the marshmallow update.

Strange charge issue anyone had this happen yet?

Not sure if was just a bug, but last night I put my phone on charge before bed and battery was at 25% I woke up in the morning to my suprise battery was only at 27%, I unplugged USB and re-plugged in again and it charged like normal.

Well, I had the same issue when I woke up this morning except in my case, the power brick has died completely and I am trying to determine if the battery has as well...
It does say it's charging on the lock screen when I connect it to a computer but in 10 minutes I haven't seen the percentage go up
FYI I have charged the device overnight only 9 times since I got it, GREAT JOB HTC !

Did you have ultra battery saving mode enabled to turn on automatically? Last time I had this enabled my phone wouldn't charge on a stock rom and stock charger. It only happened in 24 hour span, and there were times during that time when I plugged it in and wouldn't charge. I was on the latest update and after I disabled ultra battery saving mode I never had any charging problems

Nope all berry saving modes was off. It charged fine last night from 40%
I going to try run battery down today and see. Very strange

I can hear some noise coming from the charger while it's working louder than the M9's charger and a sound whenever I disconnect the charging cable from the port, like if something was a little loose. Are those normal things?

I recently had this issue too on a totally stock Verizon phone. Phone wouldn't charge until a reboot.
Sent from my HTC6545LVW using Tapatalk

I assume you guys are all using stock charger and cable to charge? I think QC 3.0 can be picky about the cable used. Haven't had any issues with the 10, but previous phone was a lumia 950xl. It was only QC 2.0, I used a third party cable with it, had a lot of bother, then used stock cable and everything worked perfectly.

I had this happening once and the issue was for some reason the cable wasn't plugged to the wall adapter properly. I removed it and plugged it and it started working. I don't think it's something to get worried about.
Not sure about the noise though

That's normal. It's a switching-mode power supply (SMPS for short) and there's some coil whining in there. Quite literally business as usual.

Not sure if there has been any update on this, but I'm experiencing the same issue as well. I have a stock charger + stock cable as well as two Anker chargers (both QC3, one wall and one car charger) and I use iOrange-E cables (56k ohm) with the Ankers. I only have this problem with the stock cable and stock charger, the 3rd party chargers haven't had any issues yet. I will plug the phone in for the night and a majority of the time (it's happened 5 or so times in the past week) it will charge for about 10 minutes or less before it just stops charging. It acts like it's been unplugged entirely. I have to unplug and replug the charger to the wall a couple of times before it will start charging again. It will again only charge for a short period of time before it stops and repeats this. Since it's only happening with the one charger I'm left to believe that maybe the charger is just faulty. Anyone else still having this problem or has come to the same conclusion?

Yes!!! I've had this issue with the stock charger as well... very weird. Just doesn't charge and have to unplug it multiple times to get it to work
I also have an anker wall and car charger along with an anker cable... they work fine
Verizon stock phone... hasn't happened since ota

Well I just experienced the same I guess ..
The cable is still okay if I plug into a different charging head/block it charges but it does not with the original head... Its weird... Not even after restarts and so

Started having the issue a few days ago. Phone will not charge until I plug it in and then reboot it. Doesn't matter what cable, charger, etc... I use, and yes I have tried them all. Stock, anker, qc 3 certified, non certified, doesn't matter. It behaves the same no matter what. Even went back to stock rom and same issue. Tried a couple of different kernels too.

This now the only way my phone will charge. I have probably ordered 3 sets of QC 3 certified chargers(car and wall), the stock one that came with the phone, probably 20 different cables, even some being micro USB with adapters, flashed all the way back to stock unrooted, wiped sd card, formatted data, tried several different kernals and roms. The only thing I have not done is go back S-On for completely out of the box stock, just dont feel it would make a difference at this point. Did yours simply just start working again dottat?

Android 10 Charging issue

Hey, so i just received the android 10 update. I was already running the android 10 beta for some time now. After the update, my wall charger (Tronsmart, type C with PD) stopped working. I was able to rapid charge my pixel with the same charger earlier, but now it simply stopped charging. I used 3 different type C to type C cables with that power brick, but pixel doesnt get charged whatsoever. I tried using some cables that i had lying around, which are not really the top of the line kind of things but still usually get the job done. These are usb C to A cables that I have used previously with my pixel. However, after the update, the phone shuts down within a couple of minutes, if i connect any of those cables. I searched around and some people have had the same issue after android 9 beta update. Using an old toothbrush, i gently cleaned the charging port, but nothing changed. Right now, i am finally able to charge phone with my PC using an old type C to A cable that shipped with my old HTC 10. However, my computer says usb device not recognized and as you`d expect, its charging pretty slowly. I even tried resetting the phone but the problem
Any ideas as to what might have caused this? Any help in this regard is greatly appreciated.
TIA

My wife noticed the same thing on her 3a since the update

I also experienced the same problem since i upgraded to android 10. Been roaming google for possible solution, found nothing so far except rolling back to android 9 or wait for an update to fix this bug.
I charges my phone with a usb a to c cable using a power delivery compatible brick (18w, 3A), it is able to fast charge my pixel.

I had to RMA my first phone due to this issue. If you google search pixel 2 xl charging issues you'll find many people who have run into this issue. All of them pretty much end with "RMA phone".
It started out my third-party charger would reboot my phone the moment it was plugged in. My original charger stopped charging the phone soon after.
My computer would only sometimes (1 out of 15 - 20 tries) read my phone so I could unroot it. All of the other times it would pop up as unrecognized.

This is typically due to a hardware issue (loose/damaged port circuitry because of bad quality components or soldering). It gets worst and worst 'til nothing works and phone reboots when you connect the cable... and RMA is the only solution.
IMHO, mainstream usb-c operating amperage is too hard on the ports, specially due to heating. I would prefer to have a not so fast charging technology that would not damage the phones. And yes, this happens on many usb-c phones, not only Pixels.
But hey, maybe you have a different problem related to software

My phone is powering down sometimes,when i plug the charging cable.This happend after android Q update.

Rotating the USB-C cable helps. One orientation (no charging / or slow charging at best) the other orientation rapid charging.

Sadly it appears a number of our phones appear to be having charge port issues as they age...
Sent from my Pixel 2 XL using XDA Labs

Not sure if it's because I recently flashed the latest 10 factory image (2 days ago) but my device charges on all the cables, chargers and on the PC as it did prior to flashing the 10 factory image, I even get the charging rapidly notification...
Did this happen immediately to those who are experiencing it? Or did it happen after some time on 10?

Well, glad I came across this thread. I've been having troubles with charging in the last few days also.
TL;DR: Starting this past Sunday, my chargers would report "charging slowly" and not really charge the phone, whether in normal mode, safe mode, or off. Updated to 10 on release day. They all magically started working last night.
Story version: Woke up Sunday and pulled my Pixel 2 XL off the charger to find it at the same percentage battery was when I plugged it in. When I plugged it back in, it reported charging slowly. It's plugged into an Anker USB C to A, and the Anker IQ two port charger. My Wife's PIxel 2 was plugged into the other port, with another of the same cable. It was charging fine. I unplugged hers and plugged mine in, reported charging slowly. I grabbed my Anker battery pack, and used the included USB C to A cable that I've used before, got "charging slowly." I rebooted the phone and got the same results. I powered it down and left it charging, same results. I tried safe mode, same thing. All these chargers/cables/battery packs work perfectly fine on my Wife's Pixel 2.
I was in the car and tried my cable/adapter in there. That one worked. I have a CableMatters 2.0 amp lighter adapter and an Anker braided USB C to A cable. I brought the cable and phone in the house, and tried the cable with my existing Anker 2 port wall charger and it worked. Weird why it would work for my Wife's but not mine, but oh well, at least I could charge the phone. Later on, I took the car cable and connected to the battery pack, charging slowly. I brought it back to the Anker wall charger, charging slowly. Tried my laptop and PC USB 3.0 ports, charging slowly. I brought the car cable and the house cable back to the car, and both cables worked just fine in the car. So, at this point, it doesn't appear to be a cable issue, but something intermittent with my chargers.
I dug up a Monoprice USB A charger I had, that has a 2.0 amp port. Tried that last night, and every cable I have charged normally with it. Just to further test, I then took the cables back to the Anker wall charger, and it worked also. To make it more frustrating, the Anker battery pack also started playing nicely and charging. I feel like it's a software issue with the phone, but I have no viable proof of it. I upgraded to 10 on launch day and have had no issues since. The only other thing I did was install Accubattery after I had an idea to try and monitor charging rates.

I did the October 2019 update and noticed this morning zero charging over night. I use an Anker multi-port brick with 2-ports fast charging. Thanks for the Accubattery idea. It shows 1 Amp charging off the 2.4 amp port. I may have to roll back the October update if I can.
I have noticed over the last few months that the screen uses a huge amount of battery. I can see the percentage drop as I scroll through the news.

Guysss I found the solution ! I had the same problem but this easy fix helped me ! Hope it's gonna work for you.
First you have to drain your battery to 1 or 2 %
Second step, hard reboot your phone (long press lock for 10 s)
As it's without battery it won't reboot but it will show the low battery sign.
Plug in your fast charger and it will show the sign that it's charging, wait a few seconds, boot your phone without unplugging the cable. And that's it. It should work.
I can't believe in so happy it got fixed for me I was suffering for two weeks after the update and no response from Google. The firs time in long time I see 70%>>>
---------- Post added at 11:07 PM ---------- Previous post was at 10:48 PM ----------
Update : if you don't want to wait for your battery to drain, you can do this instead.
Long press volume down and power for 10 sec.
It will take a screen shot (normal) but wait for the 10 sec.
You will have a menu, choose using the volume up and down to navigate "power off" ( by default it will be power on).
Plug your fast charger and it should start charging

ive tried doing the second option and i never get a menu, it just straight up reboots.
my problem seems to be similar to those stated here before. i cant use my original charger that came with my pixel.
i can use the usb c port on this (https://www.amazon.com/gp/product/B0778JNN4B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) with any of the cables i have. none of the cables will allow me to use the original charge brick anymore. i can use the only usb c -> a cable that i have. (its the standard one that comes with the nintendo switch pro controller) i even tested with the nintendo switch dock cable and it seems to work fine. i am outside of warranty so i cant have google fix it any longer(literally started issues 20 days after my warranty ended...). im gonna try draining it down till it dies and try my original charger again to see if it will do it but i was wondering if anyone else has come up with any other solutions to this problem. im thinking about reflashing it to see if that will do it and if that doesnt maybe go to a custom rom to test that even just wondering if anyone else has tried these options so i can have an idea if its gonna possibly work for me or not

hi man.
So weird you couldn't get that menu, try holding for 20 seconds instead of 10 seconds. It should work keep doing it until the phone goes off completely.
Trust me I did it again and it worked. Every time fast charging stops working I do this trick and it works.

idk, i have tried holding it even past the point of it turning off and still no menu, but i finally got it to die completely and it still didnt seem to be working on the chargers i was having issues with, after going for a ride in my car and using AA oddly enough it seems to be working fine, no idea.

Try holding the UP volume button and power.
Mine just started doing this, I left it plugged into the plane the whole trip flying overseas. (Probably shouldn't have done that)

Fast Charger no more after update

Hi,
I wanted to know if someone else has a fix for not fast changing after the last update.
The fast change option is activated, I tried different cables, different chargers and still no fast charging.
If anyone can help....
Thanks

No problems with fast and superfast charging of my N975F after last upgrade to 6DTJ4...

No such problem here. You may try another fast charger or another USB3 cable (if possible). Usually the cable is the problem or low wattage from the power socket. Not the charger or the phone.

I've had same issues since last update, including moisture detection warnings whilst phone is plugged in. Some complaints of this on Samsung Members Forums as well. Mine is + 5G UK variant so not sure if you have same variant?

Clear system cache on boot menu.
If it was a major update ie 9 to 10, reload.
If an OS is running fast and stable, I leave it alone. I've seen updates that trashed a phone once too often.
I at least wait until it has a proven tract record.
