Slow charging problem

Hello all,
Since yesterday I have this very strange slow charging problem.
Yesterday I charged for a little bit my Mate7 from a car charger. The charger works and the cable also, used it to change my note3, note4, oneplus one and never gave me any problems.
I charged it for 10-15 minutes from a car charger which for a fact I know that it's working properly. This morning the battery was 8%.....I'm changing it for 4 hours and the battery is only at 55%?
Anyone else had this problem? Any ideas on what's going on?
Please help

Root charge again

Why should I root it in order to charge it as before?

Are you able to solve the issue. I am also facing same issue. I have changed charger , factory reset the phone but still its charging at extremely slow rate.

Same problem here. Has anyone a solution for the slow charging? I just charged for over an hour and it went from 22% to 25%. Original charger and cable.

Exactly same problem .
I have changed the firmware to official lolipop 5.1.1 but there is no difference.
Start charging at midnight and at 7 h am, 40% battery!
The phone is charging but if I must charge for 24 hours , this is a big problem.

This problem is only on Lolipop or same on Kitket?

I don't know but i am in lolipop

i think it is only Lolipop problem,i have the same broblem ,but not every time to slow charge.

Buy yourself USB power monitor on ebay or amazon (they arent expensive) to see how much Amps is getting through. I had three different cables and only one of them charged with 1.7A. The other .085A or 0.99A.

Please check if your data cable works when you connect your mate 7 to pc? By it I means if your device is deted as media device or it only charges ?

This problem used to happen with me .. look
the problem isn't actually the charger itself, it's the USB cable. It needs to be a genuine USB cable that came with some phone, I use a samsung one that came with a note 3. borrow one or get it, or get a full charger.
those USB types work
- HTC , Samsung , Huawei
But first, You need to get a samsung charger 5V >> 2A " you just say to the seller, Samsung fast charge capable charger"

my Huawei y6 is now slow charge from 50 to 100 it take around 3 hrs . i use the original charger.what could be the reason ? And how to solve this ?

Wireless charging issues

Sometimes my Note8 does not charge on my Samsung fast wireless charger. No, this is not a position issue.. Sometimes, it just doesn't charge. The solid bluelight of the wireless charger although turns on. The only way for me to wireless charge again in this state is for me to reboot the phone.
Anyone else run onto this? Very annoying and it happens at random times.

I am surprised no one ran into this issue. The only thing I can think of that would cause this is some service I disabled.

I have the same issue and unfortunately have not figured it out. Mine will charge for about 10 seconds then will start blinking, I am using the dock fast charger from before the note 8 though not the newest one.

I had the same issue when trying to use the older wireless charging stand. I think it's a power issue because I tried an older iPad charging block (one of the bigger ones that has higher wattage or voltage or whatever) and it charged fine on the older stand. It didn't say it was fast charging but it did charge faster than average. I think I'll just stick to the newer charging base I got from the Note 8 promotion.

I had the same issue. I realized the case that i was using was the issue. Had to take it off to use the wireless charging.

I noticed the same thing recently. The wierd thing is, I also have the old original flat slow wireless charger and I use tha every night with a case, it just won't work on the fast dock one. Only without the case, or I think if i lay it sideways it works.

If it is not the case...
This issue has to do with power supply. Try different cables or wall plugs. I have had this issue in the past it could be sending too much or too little voltage. It blinks like that and turns off to protect your device from getting damaged.
I actually had to use an older wall plug to get my older wireless charging pad to work. The quick charge wall plug was pushing too much voltage.

if I remove the case it works perfectly. With the case its the 10 second deal; However, I took your advice and switched out the charging brick to another samsung fast charger ( all i have to test with at the moment) and it looks like it may work. I will see if I have a better one at home but it may just be with the case its having to emit more power like you mentioned. not sure but ill try that out for now.

I have three different but the same Samsung fast charger and I have issues on all three but at random times.. When it is not working, I just reboot my phone while on the charger and it starts charging again when Phone comes back up. I just dont get it.

Looks like a common issue where the old wireless charger (pre S8 ones) had problems. My fast wireless charger had no issues with the S7, just the Note 8.

Many users are facing this problem. While searching the web I found one user giving the best solution for this problem at Samsung community, He says that he has the same issue if the phone is standing straight up. However, when he put it on its side he never seems to have the problem.

Yeah. I saw that but its still not working correctly for me.

Anyone notice that it only charges when the screen is OFF?

I have this issue sometimes randomly on the new flat fast charger. Does this with my wifes S8 as well. My older standing type fastcharger that I got for my Note 5 works flawlessly. I feel like it's the flat fastcharger base itself.

Ummm... now this crazy phone is charging FLAWLESSLY. And I havent changed a thing...

Galaxy S8+ 'Slow Charging'

Evening All
So the last few weeks my S8 has been charging really slow.. it doesn't actually say 'Slow Charging', it still pops up with Fast Charging when plugged in (original charger with no damage).
It used to charge from pretty much dead to full in about an hour or so but now it's completely different. When I plug it in from about 20% it says around 2 hours to fully charged with fast charge.
Anyone else had this issue? My charger seems fine, always treated it well etc. My carrier (EE) has told me to contact Samsung but I just thought this would be worth a shot first.
Thanks
Steve

Even original cable charger works both ways, one side its slow charger and other side is fast. Try to change charger sides in the phone.

I am experiencing the exact same problem with my s8 plus. Its just been the past few weeks. I've tried switching out the cable and the AC adapter and nothing. I think I read somewhere that a recent update killed fast charging on some s8 plus models so I'm hoping that If it is a software issue it will be fixed when they roll out the next update. Otherwise I don't know what to do.

My guess is your comment is an attempt at humour, alternatively you are misinformed.

Dash Car Charger with OnePlus7Pro

Anybody tried using your dash car charger with the OP7Pro ?
I recently bought 1 and tried charging.. it shows rapidly charging and a lightning icon appeared just for 1 second and turned back to normal charging.
Then it randomly turned into that state for a split second and then change back to normal charging icon again.. any idea what's going on ?

Got mine on release day and it has been working perfectly. Have you tried with the cable the phone came with? possibly a faulty cable. If it still doesn't work, then the charging unit might need replaced.

Is your car charger Dash or Warp type ?
Cable and Dash Charger both new for me.

I have the warp version. Sorry didn't read close enough to see you were using the dash version. In any case, i would reach out to oneplus about it. Most likely a back charger and just some bad luck.

yea, i'll try to get it changed mayb... but the incompatibility issue might be there too tho.

I have the dash charger from the op5 and issued it on my op6 and I couldn't justify the $50 for it and put the $50 towards the 12gb instead of the 8gb version.
With that said, I get the same speeds that I had with the dash car charger that I got with the op5 and op6. It shows rapid charging not Warp charging. That is now than fast enough when I'm there car, especially since the battery life is better than my op6 was.

thanks for sharing.
so your Dash Car Charger works as Rapid Charging for your OP7Pro?

Will have to test my 7 Pro with the Dash Car Charger tonight. Will report back.

Yeah it shows rapid charging ok my lock screen
---------- Post added at 03:12 PM ---------- Previous post was at 03:09 PM ----------
I can be using maps while driving and still be charging fairly quickly. It isn't quite a fast as the op6 did, but that was a 3300mah battery and the 7 pro is 4000mah so that's to be expected.

Hmm is your 7pro on the 9.5.8 update ?
Weird.. cz mine shows rapidly charging for just a split sec and then change back to just normal charging. Maybe a faulty unit.. but I found 2 other person facing similar issue in another post ?

Yep, I updated to 9.5.8 the same day it was posted. I just flashed the full OTA with local upgrade and kept root and TWRP.
Also, I think I read somewhere that said OnePlus said they will charge as fast as the charger is rated for but the earlier phones can't charge at warp speeds obviously. So a Dash charger will charge the OP5 and OP6 at rapid charging and the 7 Pro should as well but using warp charger it would only charge at Rapid for the OP5 and OP6 (what the phone will allow as well). I'm curious if anyone can map the charging voltages and see whats what? Maybe yours is bugged and IS rapid charging or mine is bugged at not rapid charging even though it says. Either way All I know is it does charge fairly quickly even when I'm using maps while charging using the Dash car charger.

Works fine for me OP7 Pro 8/256 and Dash Car Charger (bought when I had OP3)

Alright thanks

I have the same problem. Dash charge will flick on for a second then flick off for about 20 seconds. Repeat this over and over during the charge. The funny thing is, occasionally it will actually start to Dash charge and stay on until fully charged but that happens only once in a while.

yeah some forum members said theirs worked... btw we came to a conclusion that its more of a software problem, tested anew dash car charger and also a new phone.. same result. confirmed that my dash car charger and my phone aren't faulty.
but today in the morning, when my phone was at 90%, i plugged in the dash charger, it shows rapidly charging after 10s of plugging in.. and stays there., charges faster than normal ( at dash speed )
normally when its only charging at the normal speed, from 50%, the indicator shows 1hour 30min til battery is full
mind check your phone battery level when it rapidly charges constantly?

I'm gonna have to check on my OnePlus charger. I'll report back if there is an issue.

My old oneplus wireless is working fine, but using an even older oneplus charger with just the cable doesn't charge at all....
