The Note 4 seems to have charging problems.
What I see is this: on stock rom, stock marshmallow, the phone charges very slowly. As others noticed, this means that when using the phone for car navigation, I have to lower the brightness so that the charge goes up and not down when connected to a 2.1A charger.
Now the interesting things: same phone, with different ROM, seems to charge faster. I also have a Note 3, and that phone doesn't have these problems.
Many say that it depends on the charger, on the cable, etc. That is true. It does depend on charger and cable. I tried many chargers and many cables. However, same chargers and cables don't have such a big problem with a different ROM, and don't have the problem with the Note 3. I tried both with fast charging turned off and on.
I feel this is some problem with the kernel. So, I wanted to ask if anyone knows what kernel doesn't have the slow charging issue, and can be used with stock, 6.0.1, or if the problem can be solved in some other way.
thanks!
Just an update. I switched to kernel BeastMode r56.8 RAGE, and charging is much better.

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
I really do not know where to begin or even explain the issue I am currently facing. I do know that it is extremely irritating and completely destroys any faith I have in future OnePlus products. I have been with Android since the beginning and never had I have an issue with any phone. Here's the issue: currently I am using stock 4.1.6 rom, but earlier (as in the last 5 hours) I was using the latest update (OB11). At first I figured the issue was related to the latest firmware, so I switched between roms then quickly realized it couldn't be a rom, so I continued to try different firmwares: OB8, OB9, OB10, OB4.1.6, and OB11. The issue I am having is very hard to detail unless you are actually looking at the phone itself, but I keep getting a blinking red notification light when the phone is plugged into the stock power supply unit (aka - receptable dash charging block). I have tried using a car charger with the same results, but less frequent. I believe the issue may actually be the block itself. However, I have tried plugging up directly to a laptop and still get weird results. The phone will connect to the laptop, but will not charge or sometimes you'll see the lighting bolt, but the phone itself will not go into a charging mood. Now i have read that the batteries supplied with the phone are somewhat crappy. Im asking to see if anyone out there has had issues when trying to charge their phone. I have also noticed that the phone no longer says fast charging or dash charging. I honestly can not remember what it says. It doesn't seem to charge quick at all. It makes no sense to me. I'm pretty sure it's not a software issue as I have literally tried every current rom available.
Could it be damage to the USB connector on the phone? Sounds as if the data + and/or - cable doesn't connect which makes it impossible for the phone to check wither the charger is a dash charger or not causing the red blinking, I dunno but maybe. I suppose you've tried also with another cable as you did try another charger.
It was the charging block. My dog had pissed on the damn charger, which shorted out the circuitry. Right now I'm using an iPhone charging block with original USB-C cord. There is no dash charging, but I don't have any other issues with blinking red light.

I recently bought 2 new Nexus 6's and am having issues with the stock charger phone charging status disconnecting and reconnecting about every half second till I unplug it. The first thing I did was upgrade the phones to 7.1.1, other than that the phones are both stock, non-rooted, etc.
Things I've tried:
Stock devices: phone #1 with charger #1, phone #1 with charger #2, phone #2 with charger #2, phone #2 with charger #1. (Fail)
Various known working cables with stock charger and phone combinations. (Fail)
Different outlets. (Fail)
Different chargers. (Success) All of my other chargers are old school and do not have turbo charging capabilities.
I am wondering if maybe this is a software issue? Did one of the updates break turbo charger support? I didn't test the charger before upgrading to 7.1.1.
I am also wondering if maybe this is just how turbo chargers work? Maybe they turn on and off quickly (Pulse Width Modulation style) to keep the battery cooler or something?
I have also read of people who get notifications saying they're phone entered a turbo charging state. I see no such notifications. Not 100% sure if Nexus 6 usually shows a notification for that.
Any suggestions would be appreciated. Thanks for the read.
TLDR: Charger issue???!#[email protected]#$TERGAVADFG
Anyone? Even a response saying "yes this happens with mine" or "no this doesn't happen with mine"?
Could be "normal" for all I know.
I have never heard of this. Certainly doesn't happen I my phone. I would suspect the USB cable first.
It's been several years since I've run stock. I can't remember if the turbo information is shown anywhere but in the battery stats. On the pure nexus ROM, it's on the lock screen.
Oddly enough my phone did this very thing. Same as yours, brand new and stock charger. I actually had a few other chargers and they all worked normally albeit very slow.
One day I decided to give the stock charger a shot and wouldn't you know it would charge for two seconds then not charge for two seconds while plugged in. Your results may be different but if I left the phone on the charger after about 3 minutes the phone would start to charge normally. Might be worth a shot if you haven't already tried leaving it plugged in for any length of time.
@n0ts0smart, the time you tried the turbo charger and it stuttered then started working, was your phone battery mostly run down?

I was wondering the same thing I think you are. This issue does seem to be related to turbo charging mode. Tested the battery issue when the phone was at 90% and it charged just fine.
This issue only seems to come up when "turbo charging".
Okay. I have tried 3 sets of 2 "new" phones (second set was reconditioned). So 6 phones, chargers, and cable combinations. Always seem to have the problem. It happens when the battery is "very low" I don't know at what percentage it starts happening. I strongly suspect "Turbo 2" charging mode. Stock rom updated as much as possible also tried Nitrogen os (android 7.1.2).
No matter what I try this problem persists. Yet I can't find a single mention of it online anywhere.
Decided I'd create a video to show it in action. Current rom is [ROM] ► [7.1.2] ► [shamu] ► Nitrogen OS N ► OMS (Substratum) ► (17.Aug.2017).

So I recently picked up a T813 to replaced my Nexus 7 (2013), I've had a few weeks now, and as with all my devices I slow charge it. This tablet generally took ~30 hours or so to charge at 0.35-0.45 amps, but I didn't think anything of it. This week I went on a trip and plugged it into a charger that can output anywhere from 0.8 to 1.8 amps depending on the port you are using (all the current ratings I'm listing are what I've measured, not what the devices are rated). My tablet said "Charging" at first, but then once it hit 75% all it would say is "Charging Slowly" no matter what. Now that's all it will say. Sometimes after a restart it will say "Charging" briefly, but then it goes back to "Charging slowly". The charger I was trying to use was an Anker product, so not a complete "no-name" charger.
I did some more checking and it appears my tablet has an upper charge limit of 1.5 amps using even the factory charger which is rated 2.0 amps. That same factory charger plugged into my Nexus 5X outputs 1.88 amps. Anything less than 1.5 amps, my tablet behaves as the rest of the devices. If I plug the tablet into a power source that current is limited to 0.5 amp, using the same cable, using an Honor 5X, and the Tab S2, both draw the ~0.5 amp.
Now the "Charging" and "Charging Slowly" messages were on Lineage, however since I have returned home, I and done all the subsequent testing, I have used Odin to return completely back to the factory Samsung software. Right now I have some videos playing to run the battery down, and am planning to trying to charge the battery all the way up using the factory charger to see how long it takes. If it also takes 30 hours, I'm going to assume it has to be a hardware problem?
Anyone else have any ideas?
My T813 arrived with Nougat on it. The only Odin firmware I could find that would successfully flash was a Marshmallow so I let videos play overnight (which did actually play overnight surprisingly!) to fully drain the battery. This morning I started charging the battery with the OEM charger, and from fully dead to 100% it took roughly 4.5 hours. So I would say this is normal from what I've read. I would say this rules out any hardware issue.
My next test will be to find a flashable Nougat OEM image as it doesn't want to update itself. Then see how it performs then. I'm starting to wonder if Samsung changed something in the firmware to make it charge slower on purpose just to prevent any "Note" like issues from happening? Finally then I'll have to also go back to Lineage, as I don't plan on using it at all with the stock software, as it's quite unbearable. There's a reason I only buy devices that Lineage is available for.
So after updating to Nougat, and letting it update, then fully draining the battery again, which again took overnight, it seems to charge even faster. This time from 0-100% taking just under 4 hours using the OEM charger, at roughly 3 hours 45 minutes.
I'll put Lineage back on it tonight, however this definitely calms my concern that I had a hardware issue. It's definitely fine. I'll see what kind of charge time I get with Lineage.
It charges with ~1600mah
I've had slow charging issue twice. I sent it in the first time and Samsung sent me a slow charger (not fast charger) to use. Worked fine for about 10 months. Once I update to Nougat, my charging became slow again.
Seems like many people have slow charging issues with this tablet. I have the Verizon tab s2 9.7

Yeah this is what I've noticed. This seems to be about the upper boundary. Despite being shipped with a 2 amp charger. I did reinstall Linage, and it charges fine with the OEM charger, so it's not a bug on their end, or a hardware problem for me. With LOS and the OEM charge it's still ~4 hours to charge with is what I would expect roughly based on my other tests, even though LOS still reports charging slowly.
I think my problem early with the 30+ hours of charge time was related to the hub I was charging with. I have been having issues where I would wake up and my phone wouldn't be charged at all. Most nights it would though, so I figured my cable was starting to go bad. Swapped the cable and same issue. Measured the current on the ports, and it was far below what it should be on a USB port, the charge ports were getting 0.18-0.2 amps, the regular ports were 0.2-0.3 amps (not sure why the regular ports were getting more). Then I noticed the power adapter was not plugged in all the way into the wall. After plugging it in all the way the current on those ports returned to normal. This honestly doesn't make any sense to me, so it maybe time to replace that hub. Either way, I know the problem is not the tablet, which calms my fears about it, since it was the new piece of hardware.
Please help me get fast charging back. Like 3 months back, my phone suddenly stopped charging fast and since then its charging super slow. Like if I use it while charging it actually discharge. While switched off it takes 4+ hrs to fully charge.
I have replaced battery, usb assembly, charger, cable everything but to no avail. Now I think its a software issue. Maybe some kernel, firmware I screwed. I have tried Syberia, Xiaomi EU, Rev OS roms as well.
Ampere app never goes beyond 300 mah reading, whatever charge cable combination I try. Please throw if insights.
Thanks a lot
