Extremely slow charging - Samsung Galaxy S8 Questions and Answers

so i had my phone for around a month now and fast charging works great until around 4 days ago where the battery percentage does not even go up by 1% while charging and watching videos on youtube and i always have the "slow charging" notification even if i turn on the fast charging feature and plug the cable in correctly.

Are you using the cable and charger it came with?
some cables i got caused the same problem i had when i first got my phone and had to invest in a good set

Are you using ORIGINAL out of box charging adapter and USB cable?
I had this issue with my old HTC One where i was using very cheap 3rd party USB cable from china and my phone was DISCHARGING while it was in use and connected to the adapter at the same time.
If you lost your original USB cable i suggest you to pay 10$ and get some normal cable (i bought ANKER for my old HTC One).

fast charging only works when screen is off.

Charging via USB Charger

I am on the road a lot and don't want to be carrying the HTC charger with me. For my Treo, I had a foldable USB AC adapter (.8A and 5V) to which I plugged in a Sync and Charge cable and it did just fine.
After reading all the comments about there being two ways to charge a Tilt - fast and slow, I decided to test out a retractable USB data cable with my USB AC brick. I set the option in Power to "Not charge the battery when connected to the PC." and plugged it in. Nothing. I then unticked the box and sure enough, it started to charge. As I was at 70% of the charge, I expected this to drag on, but it didn't. It took about 1 hour and was fully charged.
I'm still a bit worried about charging this way - the description of the Lil Sync cable for the Tilt says that while it might work, under certain circumstances it won't if your battery is below 30% of a charge. Has anyone seen this happen? The last thing I want is to go away for a few days and be stuck with a dead batttery.
Do I need to pick up a special cable from ppctechs or boxwave just to charge? Should I just carry the supplied charger?
I always charge my kaiser just using the sync cable and it works fine even from a flat battery. there seems to be absolutely no need to carry an AC adapter around when you can just connect it to a computer to charge.
Thanks Spooki. Just curious - how long does a charge usually take when you charge against a computer's USB?
it seems to take roughly twice as long as a wall charger but i work with PC's all day so doesn't really bother me, much easier than carrying a charger around.

Charger provides 1000 mA, yet phone only takes 500.

Hi,
I bought a wall charger for my N1 today. I was searching for one with 1000 mA output so the phone would charge twice as fast, but after having it on for a long time and seeing that it was only 22% charged, I looked at the battery status and it said "USB". I unplugged it, plugged the stock adapter and it said "AC", and started to charge at the usual speed.
Is there a way to have wall chargers that are NOT the ones provided by HTC charge at a normal speed? thanks!
Interesting... it happens the same thing with an iPhone charger, which have the same output characteristics as the stock charger. I never thought looking at the battery status
FWIW, you can easily see if your phone is charging fast or slow by installing the quick system info app (AC=fast, USB=slow).
I'm using the 1000 mA charger with the USB to micro USB cable that came bundled with the phone. Might it be the cable limiting the power?
I've been trying to figure this out too...
I bought a USB car charger to charge my phone in the car whilst driving.
However even with my phone on standby it still loses power.... I don't know whether it's because I'm using the USB cable or the charger is inferior.
It is rated a 1000mA (the charger).
I bought the HTC car charger from expansys.. bit costly at around £20 for a charger but it works perfectly for me. Drove 4 hours with copilot running, and battery remained perfectly charged
As well as the stock charger, I often use a pikie USB charger with a Nokia micro USB cable... phone reports an AC charger in use.

[Q] Charging issue!

I'm on a road trip now and every time I connect the phone to a charger it switches it self off.
I have tried different cables and chargers. This also happens if I connect it to my Mac.
Is anyone else seeing this?
Thank you
Funny you should post this, today is the first day at work with my DVP and I tried to use a USB cable connected to my pc that charges my HD2 and SE MW600 headset, connected it to the Dell and it turned off just like you say. Probably not enough voltage/amps, I borrowed a BlackBerry charger and that works fine.

I noted this in my "Nit-picky" stuff post. Needs a 1Amp charger.
Same here.
The only charger that worked is the one that came with the DVP.
I tried the 1A iP4 charger, 750 mA of the Kindle, a third party dual 1A (each) charger, 1A car charger, 2.5A iPad charger and finally my computer.
None of these works, but if it has like 50% charge then it charges with any of the above...

No...thats not true....But I have seen several different combinations work.
I have the Nexus 1, one of the Jawbone headsets, the HD2, HD7, DVP, and have access to the Focus and LG devices. All of these use the same type of cable.
The HDx cables, the Focus cable, and the Jawbones cables all work with sync and Charging. The LG cable does not...only works for the LG. Some of the older BB cables will only provide a sync or a charge...but not both.
The different USB charging adapters have different results also.
The DELL and HD7 adapter will work. They will work plugged into a wall or a power strip. The jawbone and HD2 usb adapter will not work plugged into a power strip at home, but, both of them will work plugged directly into a wall.
All the cables I have will work when plugged into a laptop, EXCEPT the LG. Apparently the LG cable I have access to only works with an LG.
Now to be honest, the HD7 shows no such reluctance to charge with any combination. The DVP does. My DVP does NOT require DELL only parts, but it is picky about what it will play with.
-My overnight charger is connected directly to the wall. It is a jawbone wired charger, no adapters or usb. All phones connect and charge ok with this.
-My Work office charger is a HD2 usb adapter with the HD2 charger cable.( which is strange because this one will not work at home plugged into a power strip.)
-My HOme office currently uses the Dell adapter plugged into a power strip with a generic sync cable. I say generic because I don't recall where it comes from...all I know its not the DVP or the HD7, because both of those cables are still wrapped up in the box they came with.
-My car charger is an ATT dual USB charger. It has last years model adapter, plus a USB connection. All my phones and head sets charge off of this combination quite nicely. I also have a Tmobile care charger but have not tested it yet.
There is definitely something different about the DVP and charging. I'm hoping Nicolas Cage will play the lead when this conspiracy is made into a movie.
the DVP will only charge with a 1A+ charger. the ones that come with BT headsets don't feed it enough to charge. USB cable plugged into a laptop USB port is hit or miss. The USB port in my car is 1.5A, charges the DVP really quick. I haven't found the make of the cable an issue, the DVP charges with any I've come across so far, HTC, BB, the cheap extendable cable from an airport, etc. it is picky about amps.
The cable is not the problem. I didn't mean that when I plug different cables it does not charge.
I have a charger hub which I connected many phones to it, HD2, palm pre, nexus one and few more and all of them charge from it. When I connect the DVP it shows its charging but in the morning the phone is dead, no charge at all.
BTW, it does charge from my laptop and desktop.
I charge my phone overnight on my PC and never had this issue

It will charge from the mac from 0... then when its about half charged it charges from any plug and cable combination
Sent from my HTC Vision using XDA App
I can't get mine to charge now at ALL..
Apparently it drained and shut off in my pocket. Went to charge like I normally do.. and NOTHING..
I noticed a weird behavior yesterday when charging it would jump from charging to not charging to charging. While sitting on my table. NO MOVEMENT to the cord or anything.
Tried Dell charger, tried aftermarket one (that I have been using for 2 months), and PC USB no response from the phone at all. Even tried to swap to a battery I know was low but not dead. Still no response from the phone.
The connection looks good.. but I am thinking maybe I am having a problem with the connector in the phone ?
Took my sons battery out (He also has a DVP) and booted my phone. Plugged it in and it started to charge. Then hot swapped batteries while it was plugged in.. let the battery charge up to 25% and now it charges fine again..
FUNNY it won't boot or charge while plugged in with a dead battery.. but will stay on if booted up and you remove the battery in it..

Fast Wireless Charging Works but regular Fast Charging does not.

Like mentioned in the title, my fast wireless charging works, and when I put my phone on the pad it tells me it is fast wireless charging. However, whenever I try to use the cable directly and not wireless charging, it becomes cable charging which is incredibly slow (8-10 hours for 50%).
I have obviously checked all the simple steps. I'm using the adaptive charger, I'm using a good cable, fast charging is turned on in settings. I even tried factory reseting my phone but still no luck.
Is it possible that my charging port is loose? And if so is there any way to fix this?
The other possibility I'm thinking of is that my Europe to America convertor might be bad (I have the international version so I have to use the plug convertor) I recently lost the one that came in the box so I had to buy a new one off amazon. Are there such good things as good and bad convertors or are they all the same. And if it is the convertor, why would the wireless charging work but the cable charging not.
EDIT: I just checked plugging in an S6 to the cable and it says fast charging. Does that mean it is definitely the port on my phone?

May sound odd but have you tried unplugging and replugging the charger in over and over to see if one of those times it pops up as fast charging?
i had this problem with my Note 5 (im in the UK and note 5 was not released here so i had to buy a Russian variant and they sent with 2pin to 3pin adapter)
I don't think i ever had a fix for this other than using a different fast charger without the adapter..
However like you The official note 5 charger with adapter does work to charge my s7e fine though
so our problems seem pretty similar... Maybe buy a new fast charger that doesn't require an adapter and try that?

Slow charge with original charger

Hello,
i'm new here and i'd be glad if someone can help me. So i got my phone a month ago and i noticed that while its charging (with the original charger) and while using it in the same time it almost does not charge at all, still when it's not used it does actually fast charge. As a previous samsung user, i never had this issue with samsung phones (they always fast charged even on heavy use).
That's one problem, the second one is scrolling isn't smooth. Yet my internet speed is 1GB at home although i don't see it related, overall scrolling let's say for example Facebook, snapchat, browser, it gets slow at few times and it ain't smooth like i expected it to be.
My device isn't even rooted so i haven't messed with it anyhow, running usual diagnostics and clearing apps regularly, downloaded just few social media apps so no heavy games on the phone but still i can't figure out if it's just my phone or is it the lg g6 like that.
thank you
1st i wanted to mention maybe the problem is your outlet in house but, yes G6 is charging slower when you use it on your charger.. And when it comes to fast charging to mine it tooks 1h and 40min from 0-100% bit slower than competiton models, but again fast enough.
When it comes on smoothness i am on V10T EU update and the phone has no laggs at all. It did had on past versions. But with this V10T i hadn't had any smoothness issue.. It really is great, and for playing with the phone while charging i wouldn't recommend that. It can really take effect on your battery.
Powered by LG G6
The scrolling lag sounds like there might be something making the phone work hard. Heavy usage would also make it charge more slowly than expected, because some of that power is going to operate the phone rather than into the battery. BUT I don't think it would prevent the "fast charging" text on the display.
It is remarkable how badly-behaved apps can be - I'd remove/disable your apps one at a time and see if one of them is responsible.
Try a fully compliant aftermarket quick charge 3.0 charger, it should charge much faster. Unlike a QC 3.0 charger, the charger bundled with the phone does not include 12V charging mode, so it's not allowing the phone to charge as fast as the phone can handle (the phone is fully quick charge 3.0 compliant and can charge faster than the bundled charger is capable of doing).

Yup, that's true. BUT I have s7 and g6 and both are slowly charging when I'm using them, phone would get too hot if it would fast charge while using it
I appreciate all your replies guys. Thank you.
Although i noted i dont have any heavy apps or heavy usage, the scrolling lag seems like a lag to me because i got used to faster phones before. Or maybe it is the original cable i need to change as you guys said. Anyway thanks again
I also encountered slow charging problems, but it seemed to be the cable, in some position it worked and in some it did not. I've bought an one plus dash cable for about 10 $, red one, and no problems since then. The cable is more thicker and robust, I highly recommend it.
Hi, I've got this problem: sometimes when I plug my G6 to the charger, a popup message comes out saying:
Charging slowly
Try the following if charging is slow:
- make sure to completely remove any water or debris from the USB ports.
- reconnect both ends of the cable.
- use the charger and cable that came with the phone.
Sometimes, instead, the phone starts charging normally with fast charging. If that popup comes out and I try to unplug and plug USB cable a couple of times, the phone starts charging again with fast charge.
Sometimes, when the phone is already charging with fast charge, suddenly the phone stops charging for a couple of seconds and starts again (I notice it because of the popup sound that comes if you plug the phone to USB)
I even tried to clean USB port, swapped the original USB cable with Anker cable but still using the original LG charger.
Of course there is no water in the port, otherwise a moist detector message would appear.
Has anyone experienced this problem? Can I solve buying a new charger? I'm afraid USB port might be broken

I did it recently after I upgraded to Oreo but this was happening even before I did reset the phone.

Yeah i found that funny that LG lied and tried to get by on using the chargers from the failed lg G5 shipped with the G6. They only support 2.0 charging so just use the cord and use another 3.0 block or get a portable 3.0 power pack. They are 20 bucks on amazon. Good ones too.
https://www.amazon.com/Charge-Anker...1528444548&sr=8-3&keywords=anker+powerport++1
can this be a good charger?
I bought an used G6 without charger but I have a Pixel charger model GL0102 and when I plug the phone I cant see the fast charging notification on the screen. It only say charging.
