"slow" , "cable", "fast" charging - Samsung Galaxy Note 8 Questions and Answers

I have the note 8 for 1.3 years (battery Has been replaced 2 mount ago).
Few months ago I started to charging the phone with fast charging off and the notification was "cable charging" and on the lock screen "charging: XX%".
But today for the first time, when I plugged in the charger I got message "“slow charging: Make sure charger is properly connected. Use charger that came with the device.”, and the notification was "slow charging". I wanted to make sure I didn't "lost" fast charge so I turned on fast charge, plug in the charger and fast charge was on. now I turn off fast charging, and I get "cable charging". There is any way to control "slow" and "cable" charge with Samsung charger? because I don't think there is a difference between "cable" and "fast" charging.
someone know what can be the reason it happened suddenly?

Try booting your device into Recovery Mode and wiping the Cache Partition. That should resolve your issue.

Cable might have gone bad. That's the only time I ever got that message. I replaced the cable only, now everything is charging properly again.

thanks I'll try if it happen again.

Cannot charge with wall outlet

Recently my X1 cannot be charged with USB cable through wall outlet & even car charger , but able to charge with USB cable through PC.
Anyone do encounter the same problem?
Well that's a strange one - how long was it connected to the wall?
Without getting into the discussion about volts and amps provided, and amps drawn by the phone, any method should charge.
In terms of speed, I would think the wall would charge fastest (see above), and the USB slowest.
Did the phone show on the top bar, the charging icon when attached to the wall? Or after a period of time there was no increment in the % charge showing??
If the battery was down to 0%, you probably wouldn't see an immediate increase in the % charge. The % charge is orientative, especially at both ends of the scale.

I do agree with you. Charging with wall outlet is faster. Therefore, normally I'm charging my X1 with wall outlet, unless in office, will use PC USB.
Top bar never show charging icon, but once I charge it with PC USB, the charging icon show up immediately.
It seems like no power for the USB when connected to the wall outlet. I've tested with battery removed, plugged in USB cable connected to wall outlet, there is no charging illumination light. I cannot power on it.
I tried to recall, it happened after I used a USB charger for my MP3 player. The next day, when I tried to charge with car charger. To my surprise, the USB connection notification showed up (I do remember, while charging with wall outlet or car charger, it will never prompt me for USB connection).
I don't think, it is the ROM issue. Try a few ROM still having the same problem.
From now, I got to live with PC USB :|
X1 Charging problem
I have same problem. I can not charge via both USB-PC and Wall. In order to charge the phone, I have to switch it off and then charge it.
This happened after I used CHEAP car charger from dealexteme.com
Now everytime I want to charge my phone, I have to switch it off.

let's me try with power off charging with wall outlet
well thats why se said USE only original accessories...you need to change the power ic on the board.

will the SE service centre entertain changing 'power ic'?
make sure your charger have an out put minimum is 1.Ah ,if lest than that it will not work , that is the troublem

I'm using the original SE charger!? I would not think the problem with the charger, but my X1 was screwed by the incompatible MP3 USB charger
Yep same with me, not sure why mine started doing that though, I never got used a cheap charger. Maybe its the rom... I am trying a new one now.

it's not caused by the ROM, I'm very sure. I've installed different ROM. The problem still exist.
I am having a similar problem. When the phone completely discharges , i am unable to charge it with any power adapter or even car charger. I have to initially charge the phone using a PC , then after the power is around 15% , then the phone gets charged with a normal adapter.. any suggestions??
same problem. It happends when the battery is completely discharged.
what I do is use a charger w/ low amp rating (.1) and plug it in for at least 10-20min. Give it some time, it will start charging after a while (indicated by the blinking lights). After that, you can turn it on and charge it normally
I had a similar problem twice.Both times I solved it by replacing the charger.
the same happen to me and i have another issue
my xperia doesnt work as usb mass storage!!!
the solution was buying another charger but..the usb mass storage issue still not working as a flash drive!!

It works with Z1 too. Thanks a lot!
I guess something goes wrong with battery controller

[Q] "Fast Charging" and auto-rotation questions

Just got my S6 Edge from ATT here.
I've been hearing many accelerometer problems and some people say that it has to do with the quick/fast charging thing.
While everything's working with my phone, including the accelerometer and auto-rotation, I would like to just regularly charge my phone
if that makes any sense? (Just to be safe and sure)
Need some clarification I guess:
Is there a way to regularly charge the phone with just the default cable and charger?
Is there a way to disable the fast charging option?
Does it automatically start fast charging with the default wall charger?
Or is it the default usb cable that came in the box that enable the fast charging?
I guess I could just plug it in to my PC's USB slot but I think that would be slower in general than a wall charger.
So if anyone could shed some light on this, I would greatly appreciate it.
(P.S. I have not charged my phone at all since I got it a couple hours ago, waiting for it to drain completely and then charge)

Charging Issue: Charging Slowly from USB, Charging Normal from Wireless Qi

Hi everyone, so my issue I currently have with my Nexus 6 is as follows:
Device Details: Nexus 6, rooted, running CM13, Xposed Framework installed
Charging from USB: shows "charging slowly" message on lockscreen. Ampere shows an average of about 200mA, regardless of type of charger. Tried several QuickCharger adapters and a regular adapter, as well as several different cables to the same result. When connecting to a PC via USB, it shows the same charging power, however my laptop is not recognizing that the device has been plugged in.
Charging Wirelessly: charges normal as it always had, showing a average of about 500-700mA.
The issue occurred suddenly while I was out hiking and attempting to charge via a QuickCharge capable portable battery. The previous day it was charging as it always has.
All signs point to a damaged micro USB port on my Nexus 6, but wondering if there could be any other possible causes. I'm hesitant to try a factory reset to troubleshoot it as a software issue since I have no way of connecting it to my PC to re-root and re-flash CM if that doesn't fix the issue.
If it is the micro USB port as I think, any suggestions on how to remedy this? I'm used to using my device heavily everyday and charging it with a QuickCharger as needed, so this slow charging is a significant issue right now.
Thanks for any help!
your phone charges at differing speeds at differing parts of its charging cycle. and on top of that, charging via usb instead of wall charger will carge your phone at a much slower rate. that said, we also have a "usb fastcharge" option included in many kernels/custom roms. but you also have to know that fastcharge doesnt work with every usb port that you can plug into. it only will work with certain usb ports.

Sorry, I should have been more clear. When I said "Charging via USB" I just mean through the phone's microUSB port. Regardless of whether it was plugged into a wall charger(with or without QuickCharge 2.0) or my laptop or a portable battery, or a QuickCharge car charger, I was getting the same charge rate and message showing "charging slowly", much slower than wireless charge rate which showed the normal "charging" message. The Qualcomm QuickCharge 2.0 using the provided Motorola Supercharger or my QuickCharge 2.0 capable portable battery has always worked great prior to this issue.

ok, because the included "fastcharge" is only for usb charging. but regular charging still depends on where in the charging cycle you were. for example, at 92 itll charge at a much slower rate than at 50. what battery percent where you at when you noticed?

Initially very low, under 15%. Was attempting to charge with a QC2.0 portable battery, but the device was draining quicker than it was charging. When I got home, I attempted the Motorola "Turbocharger" wall charger and got the same rate. So I put it on the wireless charger, and as it charged, I kept testing the wall charger every 20% or so, getting the same slow charge rate.
The bottom line is really that the Wireless Qi charging is functioning properly as it always has, but any "plugged-in" type charging is charging at an extremely slow rate, no matter what type of charger, no matter what % the battery is at.

odd! it could be a software issue or just a derp. have you tried rebooting? im one of the few that i know with a broken usb on my n6. and it charges slower. it used to charge at about 2400mV, now it charges at 800mV max. now that its completely broken, i cant charge it via a usb anymore, now i charge it wirelessly, which is at about 800mV max as well. anyways, try a reboot, or reflashing your software first, before doing anything extreme.

Yea I've tried rebooting like 20 times lol. Also tried doing a CM nightly software update. I'll see if reflashing will do the trick. Any suggestion on reflashing from the device? I've always used Nexus Root Toolkit and did it from my PC.
If that doesn't work, guess I'm stuck with wireless charging too. Thanks for your help!

you can flash cm via twrp recovery on your phone, without a computer. oh, and my work buddies are still in shock that my n6 wirelessly charges.. they both have iphone 6s

quick charge issue.

Hi anyone has problem with quick charge? I noticed that last night that when plugged in its charging in normal mode. I tried to move cable a bit in socket and plug again few times and after few attempts it worked as quick charge. I noticed that my USB plug seems quite loose in charging port.

The charging port (on the phone) is kinda shaky-but-tight fit on my phone too.
As soon as you plug in a charger, You see "Charging"..
And after device sleeps, you give it a few seconds and then you wake it up, it shows "charging rapidly"..
Additionally, I see this charging rapidly message - only when it is in certain battery charge percentage (withing 30-80%)
Which implies, in my opinion - that they have made sure that the device charges rapidly only when it's not working. (for heat issues, maybe)
If that's intended, I guess, that will really help with battery longevity.
Cheers,
Sony.

Ok just checked it and yeah looks like it. Yeah I'm just not worried about the port as it is shaky but yeah fit well. Thanks for help!
I have had an issue since 8.1. Returned phone to Nokia who and back with no fault found but was told to wait for July update or replace charger or cable. Definite issue.

Question about fast charging on the Note 9

Hi...
For a while now I've had a problem with my Note 9 only displaying that it is regular charging when plugged into my fast charger plug and cable. I tried a numbr of troubleshooting steps from restarting, cleaning the port, trying safe mode, buying replacement fast charger and cable, factory settings, rooting but it still only showed as cable charging so I became convinced it was a physical problem with the port. Wireless fast charging continues to work as it should.
I recently installed AccuBattery and when plugged into my fast charger/cable, the charge current completely fills the the green bar to between 1800-2000 mA so now I'm beginning to wonder whether fast charging is working ok, but the phone is reporting it incorrectly.
Does anyone else know what kind of charge current the Note 9 should have when cable fast charging please? Also, just out of curiosity, what should it be when wirelessly fast charging too please?
Thanks for any help...

I started charging at 25%. With screen on I got 2700mah.
I left my phone off for 15 mins and stayed at that 2700mah average.
When I turned my phone screen on, I had 45% but screen on charge dropped to 1000mah.
If you look at the bottom of my screenshot, it explains why you need to turn your screen off to get accurate fast charge Numbers. Your phone might throttle the screen on charge if a certain criteria is met.
Once again. Did you enable it in the settings?
I am eagerly awaiting your response... [emoji3]

Thanks for the reply.
Hmmm the numbers you get do seem to suggest there is an issue with my phone. The screen off speeds are around the same as screen on.
Samsung quoted about £10,000,000 to repair as it's rooted and they have to replace the entire board to satisfy their warranty terms.
May have a go at replacing the charging port myself.
Thanks again :good:

I don't use fast charging, ever. So that's probably why my port still works. I have gotten so much dirt in it and cleaned it out it isn't even funny. So I'm less 6 to believe that fast charging is what ruins the port not debris.
A lot of people who use fast charging have the same issue as you-,it burns out the port.
Honestly, my advice is to love with fast charging over wireless and not spend a billion dollars replacing the port. Wait until it's time to replace the battery in a year or two and do it then. Fast charging over cable only saves you 30-40 minutes. I can charge and do charge my phone normally and it only takes around an hour and 40 minutes.
