Quick charger question - Samsung Galaxy S8 Questions and Answers

I apologise if this has been posted somewhere else, but I haven't seen anything about it. When I plug my phone in, I get a slow charging notification. If I unplug it, it will fast charge the second try. It happens like this every time. Has anyone else experienced this?

I didn't look for it, but when the screen is on, the phone charges at a regular rate, but when screen turns off, then it starts charging fast.

That is interesting. I don't have any of that. I do see fast charging indicated on the lock screen and in the notification shade/panel. I recently started using Samsung's wireless charger which also indicates "fast charging", although it is a bit slower than the cable charging.
Try different outlet, different cable(if available), turn off the phone and try charging and look for how fast it charges, of course it won't tell you if it is fast or regular charge.

Try to blow air into usb-c port, maybe it's just some dirt.

Anyone having charging issues?

A friend of mine just picked up a Droid X today and he's having problems.
First, the charger it came with doesn't appear to charge, there is no charging indicator light.
I attempted to use a number of USB chargers, the first from my HTC Hero, another from an iPad, and a third is a cheap Chinese AC charger with a USB port that I picked up for my EVO.
The only charger that turns on the green light on the top is the cheap Chinese one.
If I plug it into my computer, I can also get the green light to come on, but it doesn't appear to be charging it. When the phone is on using the cheap charger, the phone appears to work, but says on the lock screen to plug the phone in.
Further, the lock screen is not responsive. We let it charge with the phone off for about a half hour with the green light on, the phone boot up and had a little bit of life and the screen did work, then it suddenly turned off and won't boot past the Motorola logo (just flashes for a couple of seconds then disappears.)
So, whats the verdict? Hardware problem or is anyone else experiencing this? The phone did completely die, so I wonder if that caused a problem of some kind.
Do you have a Green light when charging with the phone off? Does the light flash red when it's on and charging?
Thanks for the help!
I plugged it into my home computer and nothing happened vs. being able to charge my computer and nothing. Although the phone was about half way charged before I plugged at work, vs 10-15% at home.
Mine didn't charge while plugged into my netbook, but does charge while plugged into my PC, and definitely charges while plugged into the wall charger.
Update: After using the wall charger and fully charging it, I connected the Droid X to my computer and it now syncs up. Maybe the amount of battery power matters?
I don't think the green blinking LED is a charging indicator. Mine charges without it....but I notice when I was charging it the first time, it was going off when I had an unread text message. Is everyone sure the green LED is supposed to be a charging indicator? Mine's charging right now according to the bar on top when I turn it on while it's plugged into my computer.
I'm having a charging issue with my car charger.
When I plug it in to the car the audio volume drops to almost inaudible and the voice commands don't respond anymore.
This is with all the volume sliders set all the way up.
I have to reboot the phone in order to get it to work again.
I've charged it connected to my PC at home and work and it works fine with those.
Wow, the OP totally describe my problem i had too. I went back to Verizon and got another battery. My first battery wouldn't charge above 50% and the second came with 80% and we tried charging it at the store and it never went higher than 80%.I read on another forum that the charging indicator only reads at every 10% intervals, so that may be the problem. The rep and I at Verizon was watching it to see if it would move up to 81% so we would know it was working(beside the bubbles moving animation) and it didn't and we gave up, I will see what happens when I charge it tonite with the AC plug for the first time.
So the green LED light is not a charging indicator. Apparently, there is no charging indicator at all.
We left the phone off and plugged in with the stock charger, no light, but it did gradually move up.
I did some searching on the Motorola forums and another user ran into the same issue, he said that leaving the phone off and charging it for an extended period of time solved the problem.
I have no idea what the green light meant when it was plugged into my cheap Chinese charger, it must have been nothing.
It wasn't a text message or any other kind of notification since it was on only when the phone was completely off.
Before he left with the phone it was up to 90%. A brief press of the power button brought the phones battery state up, but didn't boot the phone.
Hope this helps anyone else with issues. Just plug it in and let it sit overnight.
I had a similar issue the first day.after overnight charge all seems normal for day two.

The only charging indicator is the lock screen part if you just turn it on it will tell you at what point it is charged.

It will occasionally show 5% intervals when it gets below 20% (I've seen 20, 15, 10, and 5% intervals).
I've noticed my phone doesn't like charging from a computer while the battery is really low. Once it's had a little bit of a boost from the wall charger, it will charge fine off the computer.
I just changed to a new one today.a friend of mine is having the sand issues. As so did i. It seems its not the battery its a short on the ground on some phones. Its pretty awkward but it has only been a handful from a batch of thousands that were released. So were in good money.

Is this good or bad?

When you said charge fast you're referring to wall charge? Car charge? Or usb charge?
Stock X
Hey guys,
Figured I'd swing over here and give this a bump for a buddy of mine. Seein if this may be a slightly common issue.
The situation(for him): All on stock phone NO ROOT
- No charge on wall/home charger. Shows charge indication but does not actually charge whatsoever.
- No charge using PC usb cord to charge.
Again everything is stock and not currently running any app killers or really anything out of the ordinary as I can tell. The only thing he has purchased and is running that I am aware of is Launcher Pro. The issue has been brought to the attention of Verizon which is his carrier and he just received his 4th phone! Honestly thats the only reason I'm posting an inquiry into this hear. A simple google search results shows others with similar issues(posted link at bottom). He has purchased a new battery and wall/home charger along with another USB cord. All 3 phones he has had produced the same issue with all of the charge accessories(4th phone just received so no tests as of yet, but i put money on it doing the same thing). Verizon has been willing to replace every phone so thats not a problem but seriously! Is that the only answer?
any help is appreciated in advance

There are two charging indicators, no lights! One is on the status bar, you'll see a lightning bolt through the battery meter, and on the lock screen it will say charging as well with a %.
Absolutely, yes sir. Both indicators(lightning bolt in battery, and battery charge indicators) light up and show charging. Although once phone is unplugged it will keep whatever the charge level indicates for a random amount of time usually between 1min-15mins then the battery indicator drops immediately and shows an almost dead battery. As in charge shows 80%, unplug and within mins phone shows 10%.
Also:
- There are no other indicators of charging other than those mentioned (as it should be).
- The phone connects to PC just fine for mass storage. Files transfer with no problems.
thanx again!
So... which one is it? First you say no indicators, and now there's indicators but it just doesn't hold charge. is VZW replacing the phone or the battery? sounds like a bad battery to me.
My apologies you are correct *edited post* i meant to say it does show charging as in you see the lightning bolt and everything even the battery icon fills to show a "fuller" battery although that stat drops almost immediately after unplugging.
As in replacements they replace the phone and battery as well. I know its the 3rd phone so far with the same problem.

Weird charging issue

I usually charge my phone using USB while in the office. At home, I'll use the supplied wall AC adapter.
I've noticed that even though I'm using the AC charger, the stock battery display will show Charging (USB), which is not the case. Power cycling the AC charger usually fixes it to show Charging (AC).
Have also noticed that in some instances when it's plugged into the AC charger, the charging status would switch between "charging" and "not charging". Very obvious in the notification battery icon, where I would see the lightning symbol appear and disappear, about every half second.
I think there's an issue with the AC charger, or maybe it's the charging circuit in the phone?
Anyone experienced something like this before?
Cheers

Sounds like a hardware issue. If you want to run the test yourself, you can try swapping the charger with another OEM Nexus 4 charger (don't try to get around this). But I'd contact Google about this if I were you.
Might be the stock charger if thats what your using i had the same prob and sometimes but battery would either stay on the same percent for a while or go down so chanhed the charger and its been working fine ever since i still use the stock box charger i just changed the cord

i had similar issue..when plugged it shows charging/discharging..if charging it will be slow as hell..swap cable all good..
throw away the original cable try a different one..
Thanks. Will give it a shot and see how it goes.
Do you guys think this is a charging issue? Temp is very high but still continues to charge at AC level. I have switched out my power bricks and cable but still have the same result.

It is due to temperature I believe. I have observed this behavior closely for a long time, so I'm almost certain this is the cause. I've seen it on the Galaxy Nexus and the Nexus 7. I can't tell you offhand the exact temperature they stop charging at, but I can tell you it's most likely between 50°-60° Celsius. You've got to let your devices cool off. It may be a pain, but it protects your hardware, so when it stops charging, your phone is saying "Hey partner, you think you could let me cool down for just a second? Is that too much for you or what? What's your problem, you dingdong?"..
... Or something like that. If that's not exactly what it says, it's very close.

Ah I see. Anyways, I have used my cousins nexus 4 and every time the temp goes over 38 degrees, the charge rate drops down to USB. Mainly why I asked haha. Yah its a pain from time to time LOl

Same here. Worked out for me it was a dodgy cable. Using the supplied cable through a laptop, I will also from time to time get the plugged/unplugged notification on the computer, which being audible made me realize how often it was happening.
The supplied charger brick now seems to work flawlessly with a different cable (ie, always says AC, no odd charging/not charging behaviour, etc).
Try that and see how you go.
I guess it's the cable. I've tried using a generic ebay cable and it appears to be working fine now.
What sort of mA values are you getting when using the stock AC charger?
Battery Monitor widget says that the phone's only getting around 500mA when I believe it should be getting more than that. I've enabled the USB fastcharge in the options. and have left everything at default. This is after waking up the phone from standby. Keeping the screen on drops the charge rate to 200mA thereabouts.
No music playing, 3G and connected to a wifi access point.

How do you know fast charging is working?

I have fast charging enabled. I forgot to charge my phone last night and put it on the adaptive fast charger this morning at 0809. It was at 3% when it started. It's 0958, and it's at 22%. The phone has been power on during this time, but it should be faster than this. The setting for fast charging is checked.
Is there an indicator letting you know fast charging is engaged? I thought he gave a notification when fast charging is on. I know it worked once, and I saw one.
That strange
It only take 30 mins to charge 50 percent
Make sure you turn off all service and turn on power saving or shut down your phone
When I plug my note 4 in to charge a notification shows saying fast charge mode enabled (or something along those lines)
And it appears to charge really quick, I can't be exact on time, but my fine was down to 15% last night before I put it on charge, must have been about 15 mins and it was about 35%
Once I think it charged 20% to full in about 50 mins

That's what I thought. I thought I was imagining things when it didn't appear or maybe it only appears upon first use. I even thought maybe using Nova was some how suppressing the message.
Given you response, I thought maybe there is something wrong with the power in the computer room, so I took it to the kitchen. Then, the status message showed saying fast charging is on. Weird. So, I went back to the computer room and plugged it in. Now the message is starting to appear.
I guess the adapter glitched and was stuck in lower power mode. Not sure. Any way. Thanks for confirming the status message. It seems to be working now.
While my charger seems to work fine. I have noticed it wont pull more than 1000 ma at any given time. I was under the impression that when my battery is below 50% i should see fast charging at a rate over 1000 ma? I get 1000 ma off any decent tablet type charger, including over 50%. Yes fast charging is enabled and detected when the phone is connected to the fast charger.
Anyone else seeing this? Using "Galaxy Charging Rate lite" from the app store. Is there a better app that you guys like?
UPDATE: on a 2A 5v charger I will pull down average 1800ma when the screen is off, then it drops down as the screen is off. So, more testing is needed on the fast charger, I think I need a application that will log the ma draw at intervals to see what it pulls during "fast charge mode" with battery < 50% on the samsung charger.
Fast charging mode only works with screen off!
Charging at 9 Volt and around 1000ma
With screen on the fast charging mode goes off an charging goes to normal mode at 5 Volt and up to 1800ma.

I'm sure I read somewhere on XDA it also only works from 0 - 50%.
Going from my own experience, when I plug it in, I definitely see the "fast charging enabled" message appear in my notification bar.
However it's anything but fast. Mine has never charged faster than average speed that I have noticed, but then I rarely dip below 50% if I can help it, so that might be why.
Last night I put it on charge at 1am (at 59%), came back at 01:48 and it was on %93. Is that good? You tell me. It doesn't seem it. Perhaps my expectations are too high.
One thing I was always curious about is would it matter if you use an extension lead as opposed to plugging it directly into the mains. Not sure how much voltage it is able to draw though an extersion lead, but as must of them are supposed to be up to 240 volts, I'm guessing that wouldn't make a difference.

Are you sure, I go from 5% to full in around 80 minutes with device on, is yours faster switched off?
On my Verizon Note 4 phone running Android 5.0.1, if I go to settings/battery, there is a setting for Fast Charging which you can enable if it is not already. Just below that, there is a status message that when the phone is plugged in will tell you what kind of charging you are doing. I just plugged it in with an Adaptive Charging unit and the status said "97% Adaptive Charging" indicating my phone was 97% charged and was charging using the adaptive (fast) charging. When I unplugged it and plugged it back in with a non-adaptive charger, the status changed to say "97% - Charging (AC)" indicating it was charging but not "fast" charging.

If your USB adapter is plugged into an AC outlet or a long AC extension cord that is plugged into the AC outlet it makes no difference. However if you were talking about a USB extension that plugs into the adapter and extend the length of the DC USB cord that will make a major difference.

my galaxy s4 isn't charging right

I plug in my phone, the charging light turns on, then it tells me to use the charger the phone came with - I am - so why does it tell me to use the original charger when I already am!?! And furthermore, it will just randomly stop charging and tell me that my phones battery is empty even though just a few seconds before it was at 50% I turn the phone on and it says that it's at 50% but it had stopped charging and told me that it didn't have ANY battery power, now I have to have my phone on when I charge it to prevent this, but I'm 99% sure that it would charge faster when it's turned off, why is my phone doing this and how can I change it?
P.S. what's better for charging, daydream or sleep mode?

What ROM are you using and have you flashed any custom kernel?
Sometimes you need to calibrate battery statistics in order to give correct charge.
Try a different cable.

Yes. The thin cords are 1 Amperes, while the thick ones are 2 Amperes.
Using a thin cord means it won't give the phone enough power.

Galaxy s8 intermittently not cable charging

Hi!
My girlfriend's new S8 will intermittently not charge overnight. I'd say maybe 5 times since she bought it last month she'll wake up to an almost dead battery, while it's still plugged in. Not sure if there are any messages or anything.
This is using the charger that came with it.
Anyone else experience this?

I don't charge my phones overnight, but haven't seen it with my S8.
There could be a process of a particular app that is using resources and it makes CPU work harder and/or the charger isn't giving enough power to keep things going.
Of course do simple stuff like checking out the cable/charger + try another one if you have, try different outlet....
Before putting it on a charger: Items 1 - 2 do every time you charge the phone - it is very helpful.
1) Clear all recent apps
2) Restart the device(this usually gets rid of any app that are stuck)
3) Also try to charge not overnight by couple of hours before going to bed, so it would be easy to monitor what is happening.

Thanks for the reply, but we'll find it's either slow charging (it actually says slow charging), or it won't even show it's charging/plugged in. I've tried clearing recent apps and restarting.

I had the same issue as you had yesterday
It seems that samsung did some update that checks the amperage current that it charges and if its low or unstable, the phone stops getting charging.
Try use original adapter and short length type c cable like the original, it won't happen.
