After updating to Nougat, Fast Charge works intermittently. Kinda. - Sprint Samsung Galaxy S6

Greetings all, I've been a longtime reader of xda, but never a poster. As this is my first post. After upgrading to Nougat I now have issues with fast charging. 98% of the time when I plug in my charger, it will switch between fast charging and charging in one second intervals with vibration. If it does decide to "fast charge", it will charge at regular speed while displaying fast charge. HOWEVER, It fast charges as normal with the phone powered off. I tried new high quality micro usb's and trying different fast charging samsung adapters, and doing a factory data reset. I have tried toggling fast charging in settings too. It seems to be software related. I am assuming there aren't any custom Nougat roms yet, as I cant find them here. Has anyone heard or experienced this, and have any tricks to try? Thanks in advance!

I've been having issues after installing Nougat where occasionally it will go from charging to not charging back and forth about five to ten times intermittently, though I have noticed some issues with fast charging as well.

@grandomegabosses That is exactly the issue I am having. When it does finally settle down it will tell me ridiculous amount of time to complete full charge, like 1.5 hours when I'm already at 20%. If you see the same, try charging with phone off... It should be WAY faster... Thank for your reply.

I had issues a few times where my phone was really hot after being on the charger for an hour or so just to find out that it only charged up 10% or 15% more than it was when I put it on the charger. This happened to me once with it powered off...my phone only charged to 79% when it should have had plenty of time to reach full. Powering off the phone before charging seems to help 99% of the time. Hoping my S6 gets updated again, or they'll forget about us and it'll catch on fire one day. Sad we still can't get updates from directly from Google compiled in a cloud based server @ Samsung with appropriate kernel and have a flashable package of Samsung Apps and interfaces, that could be downloaded from your Samsung account and verified by Knox. We'd be on Android Oreo already if it were setup that way...

Okay, so I did have this issue, but I've easily solved the issue by flashing stock via Odin. Nand erase all, I did an efs clear just because. Also, checked the phone bootloader update. But after that, everything worked perfect.

Charging Problems Please Help Have Had This Problem for Months and Still Do!!!

I have had this problem for about 2 months now, and it seems like everything I do, never fixes the problem. When I was rooted, I was having fun tweaking, flashing roms, and mods, but then one day my battery percentage was low so I plug my phone in the charger with the stock charger and cable that came with my GS3. I wait, 5 minutes goes by and I check my GS3 again, and it has the same exact battery percentage it had when I was going to plug it in to charge. Never even increased one single bit. So I thought to myself, that's strange. I wait another 5 minutes, and it only goes up by 1 percent. I was thinking to myself what the *beep*! Now I left it that night to charge, and I wake up... HOORAY! 100% fully charged! I take it out of the charger and BOOM! it drains all the way down, to a low percentage, which I'm pretty sure was the same percentage I had when I went to charge it last night. Now I was pissed man, phew, I got so mad! I read all over XDA and Android forums, and it seems like I'm not the only person who has this problem. There was one thread with like 10 pages and counting. There were answers like, "just wipe battery stats", I wiped battery stats, the problem still persists. It still takes a very long time to charge and, once I immediately take it out of my charger it drains, to a very low percentage. So then people were saying "it's the cable, just use a different cable" I use a cable from a Pantech charger and I wait. It charged my GS3 just like the way it is supposed too. I'm thinking to myself, great it's back to normal charging state! Then another day I plug it in the Pantech charger and my GS3 doesn't even recognize, that it is charging, no lightning symbol on the battery pic thing on the status bar. I wait and there has been no increase, but actually a decrease of battery. Again I was like what the *beep*! So I use various different chargers and my GS3 doesn't even recognize any of them that they are charging, EXCEPT for the stock Samsung charger that came with the GS3 which takes a very long time to charge and once it's fully charged and I take it out, it immediately drains to a low percentage. So I switched batteries with a friend of mine who had a high percentage, and I booted into CWM, and I wiped data/factory reset I wiped dalvik cache, and cache partition, and I reflashed my ROM. No fix. Same Problem. So I try many different ROMS, and every ROM I try. No fix. Same Problem. Even the very stable ones which supposedly have not many problems. I thought unrooting and going back to stock firmware would work. That's exactly what I did and... No fix. Same Problem. I downgraded to ICS and... No Fix. Same Problem. I have tried everything that people on XDA and other forums have said would fix the problem, and the problem is still there and it seems like it's not going anywhere.
SORRY FOR THIS LONG THREAD.
PLEASE PRIVATE MESSAGE ME ANYTHING THAT WOULD FIX THE PROBLEMS OR ANSWER IN THIS THREAD.
ANY HELP IS GREATLY APPRECIATED!

[Q] Z1c issue

Hello everyone. newbie here.
My sony Z1c seems to have developed a bug/issue. 2 days ago my phone was on charge, green led at the top was on and my battery showed at 100%. I unplugged the device jumped into bed, set my alarms as usual. I then woke up 2 hours later then i should of to find my z1c was dead. Nothing was running in the background etc so instantly knew something was up. Tried charging my phone at work via usb>pc and it kept saying my phone is losing charge quicker then its charging (never seen this message before) . I could turn the phone on but the battery level stayed at 2%, as soon as it was unplugged from the pc it would instantly die.
When i got home i done a few "reset" searches and come across the hold volume up and power at the same time until phone vibrates method. This now seems to allow my phone to charge normally again and the battery goes past 2%. However again today my phone went dead overnight. So the issue is still there, im just able to charge the device again.
I dont appear to have anything running in the background
havent done any firmware,software,app updates in the last couple of days (again that im aware off, unless they forced any)
also noticed the phone gets extremely hot at periods for unknown reasons?
Anyone here able to help or advice? is this a faulty battery, software,firmware issue etc? any fixes
d5503
running 4.4.4
14.4.a.0.108
Thanks in advance
Have you tried a different charger? Charge it using wall charger with supplied cable. I don't think firmware is draining your battery. Possible that u r caught up with a faulty battery if u don't have any issues with charger.
My advice "Head to Sony Service Centre asap".
Have you 'ever' installed any custom ROM on this phone then reflashed/restored something later after accquired? It could be the underlying system's battery state is different than the current running OS' one. Try calibrating the battery a couple of times to see if that make any difference.
Hello. Thank you for the replies.
The phone charges correctly via mains and usb(laptop,ps4 etc) since i done that power+volume up reset. Pretty sure my leads and plug are fine. i could try different usb leads though. the charge level is certainly showing me 100% charge
I have never used any ROM's or Roots. i dont know fully what they are. I used to have a jailbroken iphone so it sounds similar. Id be prepared to do down any of them routes if it fixes my phone
Everything updated has been official releases. I dont appear to of updated anything recently though so i cant put it down to a system update or new app update. - something might have glitched somewhere i dunno
Charged the phone during my first post and again it says its gone to 100% after a couple of hours. unplugged the charger. restarted the phone and checked nothing that hasnt been on for the last 3 months hasnt turnt on and all seems fine there. So just left it in standby
checked it 10minutes later to see charge levels. am down to 87%
using gsm battery app it says 68.9% app usage, when i click that
android system 53%
kernel (andoid os) 19.5%
then i have a list of other stuff running all be 2%
them 2 shouldnt be that high should they?
then when i go default settings>power> batt usage
android system 37%
googleplay service 21% (doesnt appear to be updating/syncing anything. should all be off. never used syncing)
screen 14%
android OS 5%
cell standby 5%
the rest of the list are 2's and 1's
phone was cool when charging, since rebooting the device and unplugging it, its now getting hot??? would of expected it to be the other way around!!!
Might want to give it a go of this:
userguide.sonymobile.com/referrer.php?region=global-en&product=xperia-z1-compact#!Resetting-your-device dot html
Sorry, newbie can't post URL yet:crying:
Hi again, Jcw i done a full factory result and everything now appears to be fine now. Phone has been on for 3hours standby and on 98% battery, It would have been dead by now and extremely hot at the back. Now running alot cooler. Thanks for the advice.
Have no idea what happened. Something was seriously draining the battery though. Glad its fixed. Thanks again

Battery Issues

Okay I've had my galaxy S3 for some years now. Randomly I started to have a problem with my battery. It started dying faster and faster. After that a new problem popped up where it would only charge up to a certain point, around 35-50% and then stop. Now i did try many things and i feel like theres is nothing left to try. Im not sure if this is a software or hardware issue as i couldnt figure out the problem. I have tried changer the wall adapter, usb cable, and batteries (all official samsung ones). I even got an external battery charger and charged the batteries there and put them back in my phone. What i noticed is even a full charge on the external battery charger would show as a 35-50% same as when it charges and stops charging through usb. The magic number i noticed is 37% for all batteries, chargers, cables. Slowly this started changing and now it no longer charges properly at all. when plugged into the charger the battery drains completely to 0% on charger and if left overnight will jump to 100%. this 100% doesnt last long however and the cycle continues. Sometimes the phone will die and i plug it to charge and it will be at the 35-50% spot. The only thing i wasnt able to do was test with another s3 as everyone i know is S4 and higher. Any help would be appreciated as upgrading is not an option right now financially.

Need more information. ROM/TouchWiz version, have you tried wiping? clean install? etc.
When the problem first started i was on a custom rom but this was a while back so i dont remember the actual name of the rom. I was running that rom for months brfore the problem started so i doubt it was a rom issue. After dealing with the battery issue for a while i started to get annoyed. So i unrooted and reflashed stock firmware hoping it would help but it didnt. I ran stock for a while. After that i decided to try flashing a custom rom again to see if it would help. Currently im running TMS3KK 3.1 TW 4.4.2 and the problem is still there. I have tried factory resets, wiping everything and even battery calibration apps but nothing seems to help. My battery indicator can go from 100% to 12% just by unplugging the charger. Sometimes my phone would die and den turn back on with like 40% or so. Really can tfigure this out i feel like it might be a hardware issue. Also is *#0228# command useful?
Bump
I have the same problem. Try using rubbing alcohol and toothbrush to clean out the USB port. Also take a look at this link to remove corrosion from the port.
http://www.instructables.com/id/How-to-fix-a-slow-charging-android-smartphone-enh/?ALLSTEPS
I dont think its a port issue as an external battery charger doesnt seem to fix the problem either. Problem seems to be with the phone not reading the right percentage.
I used Kies 3 to reload the firmware to KOT49H.T999VVLUFNH2. Battery is more stable now.
Yea i tried flashing back to stock as well but unfortunately didnt help me.

[Q] After update to 1.40.401.8 very slow charging

After the latest update my M9 charges very slow. It takes 6 hours or even more than that, even with the Rapid Charger 2.0
If I reboot my device before before I charge it, then it charges normally, in under 2 hours.
Any solutions?
I am trying to fing out where the problem is, and I suspect GSAM Battery Monitor Pro and maybe an app called Screen Adjuster that might somehow interfere.
I have an unbranded device and it runs the official firmware.
Is anybody else having the same issue?
Have you tried wiping the cache and recalibrating the battery by holding both volume buttons and power button at the same time for over a minute?
No, I haven't. Are there any other issues I should expect if I recalibrate the battery?
Have the same issue .. S-OFF, ARHD 8.1, Firmware 1.40.401.8
No solution yet :/
So it must be the new firmware. This is really bad. I have cleared the cache but I don't really see the point of recalibration. If I restart my device before charging, it always charges after the reboot normally...
I disabled GSAM yesterday and the screen adjuster app, but the problem remains. I wonder, is there anybody out there running the new firmware without this issue?
Same issue here. Stock non-rooted ROM, stock firmware, S-Off, unlocked BL.
Had also the same issue with 1.40.401.5, thought it would be fixed in the official update (1.40.401.8). It appears it's not... Bad news when an update supposed to solve issues brings new ones...
With 1.40,my charging is way quicker with a quick charge 2.0 adapter. GSam battery monitor reports higher ampere and a battery change ~80%/h now (from empty to 85% as usual). Before this, battery change stalled quickly but now it's stable.
Did you factory reset your device after the update?
Same problem here.
No factory reset after the update. Should I? Or is there another way?
I did a factory reset when I first noticed problem with slow charging. At first it seemed to work and it charged normal speed but now its back to slow.
My M9 will only charge when i turn it off, plug it in the ac. If its on, even though the indicator says its charging, it doesnt, help.
The update was supposed to improve (quick) charging... Instead it made it worse ;(
I'm curious if there is anyone who does not have this problem...

With the original charger?
Mine charges a bit faster with the quick charger, but only after a full reboot. And only once, after disconnecting the charger it reverts back to verrry slow charging when connected again.
I've the same issue. All stock, latest firmware.
Unless i reboot the device, it takes 8 hours to charge. If i reboot it before plug in, it takes about 2 hours.
Something is wrong were...
Same problem here but it is intermittent. I plugged my phone in earlier and it charged 10% in 1.5h on a 2A charger. So annoying!!!!
This is a big issue for me since I cannot rely on my M9 to get me through the day without having a charger with me. I am going to stop using my M9 till the problem gets solved somehow. Sorry HTC but this is a big issue for me and despite the fact that I love HTC products, I cannot ignore this issue. Back to my iPhone...
I agree on the Factory Reset, I do it every time I take a OTA update. It's jus my practices as it solved issues in the past and I kinda stick to it...

no its a real bug, regardless of the charger, when it appears only a reboot solves it
anyway the 5.1 / 2.x update is close but yea bug like that will cause serious hurt

Phone not charging or stopping charging

As the titles states, my phone doens't want to charge the first time I plug it to the original charger. It can stay for hours without charging 1%. I have to reboot and then it'll charge fine. I called google support and they told me it will be fixed in the next updates. Anyone else is having those problems? I just return it if it's just me.
I've had weirdness with charging for sure. Seemingly mostly with the charger that came with it. Mine will say "5 minutes until charged," but I'll be at like 86%. If I unplug and let it settle for a second, it will go back to 84% or whatever, then seems fine when I plug it back in again.
I've been using this Magqi charging dock and magnetic pad and it's been hit or miss. Sometimes just fine, other times won't charge at all. Wife is having the same problem. We both have a Pixel 2 XL.

ok it happened to me before (you clicked something by mistake )
just go to settings -system- developer options -select usb configuration- charging
if this doesn't work
maybe it is something else
I didn't turn on nothing by mistake, it's just not charging. I did a factory reset and seems to work fine until now ( charged just one time ). I'll update the thread if it happens again. I think something was messed up during the November update. I hope it's just a software bug because it's really annoying to reboot the phone Everytime
It happened again after factory reset. It's quite annoying
I've had mine 4 days and it happened to me the first time this morning.
To fix it I turned the phone off, started charging whilst off and then turned back on. Luckily it was back to charging correctly.
I today I now have the slow charging issue (on the supplied charger)
I ran the battery down fully last night and put it on charge at 2 am.
When I left for work at 6:30 am the battery had only charged to 67%, that's 4.5 hours.
Given all the other posts concerning this subject it does not seem uncommon
Yeah just got my phone last night and its happening for me too. Will charge for a minute or two then stops. Going to try the charge while off deal mentioned above and see what happens.
It's quite annoying for me... I hope Google is going to fix this soon. Seems like a software bug
Here is what happens with me.
I have the stock charger with a 6.5' Cable Creations C to C cable.
Any charges that happen with my battery lower than 30%, I have to constantly watch it to make sure it's charging.
If not, I have to unplug and replug. This happens several times between 0-30%
After 30, it seems to pick up fine..
Edit: Forgot to mention, when below 30%, it stops charging because, I take the power off it and all the sudden, it loses 2-3%
Sent from my Pixel 2 XL
Not sure I've seen a situation where the supplied charger didn't charge the phone at all like some have mentioned, but it definitely seems a lot slower than the charging time for the Pixel XL. It's offset in a big way by the much improved battery life I guess, but it certainly doesn't feel like quick charge, at least by 2017 standards.
However when I use the charger that came with my Pixel C, It charges noticeably quicker. I know the Pixel C never sold in huge numbers, and I haven't run any comparison tests here, but has anyone else that owns one noticed better performance with its charger compared to the one that was bundled with their Pixel 2 XL?

Tried Nexus 5x stock charger and it didnt do anything. Not sure whats wrong with our chargers, my Pixel 2 XL always goes to 98%max maybe 99%. Another weird thing that happend. I decided to fully discharge my phone until it shut off for the first cycle(first day I got it to calibrate battery). When I plugged the OEM charger in it showed the symbol that it doesnt have enough power to turn on(needs to charge to 5% or whatever it is), waited 1 hr, 2 hrs same thing. Unplugged, plugged back in, hard reset, bootloader and nothing. Same symbol. Only way to get it back charging was to use a cheap USB A to C cable I got from walmart, plug that into my Nexus 6 charger base and it finally started charging...??? WTF
Same issue
Looks like this is an issue with the November security patch.
Same thing has happened to me on my Pixel 2 XL and i have three different official Type C wall chargers from google (6p, XL (1st gen) and they will not work, however it will work with the quick charge connector in my car (Type A to Type C).
Reviewing the internet other people have the same issue and all seem post November update. I did a factory reset etc to troubleshoot with no luck.
Only thing i have yet to attempt is enroll for the android beta program and force update to 8.1 to see if it resolves the issue.
i live in Dubai and i don't have official support from google nor am i able to contact them, if some one could kindly post an update if they have tried contacting google and got a confirmation that its a S/W issue.
Bump.
Sooo, I woke up last night and saw a message on my phone that said something like, your device is corrupt, etc. Now my phone will not charge... The phone seems fine otherwise, everything seems to work, no more errors or anything, but, two stock pixel 2 chargers and neither charge the phone. However, if I plug it into a computer, it charges. Anyone have any idea of what is going on? I've rebooted, cleared cache from apps (not from twrp though), nothing seems to help.
About my phone: April update, unlocked, rooted stock. The only things I'm running are substratum with the swift dark theme, pixel launcher mods for Virus icon pack, viper audio mod, adaway, greenify, things like that. Nothing major with the exception of the theme. I even disabled/uninstalled the theme and rebooted. The problem is still there. Unless I get this fixed ASAP, I guess I'm calling Google for a replacement...
Please help!

Almost sounds like a hardware/port issue. About the only 2 things I could suggest is...1. Fastboot the factory image again with the -w flag removed. 2. Factory reset, which, as you know, bites because you have to set everything up again.

Ugh, I thought I might need to try one of those. I'll see what fastbooting the image does. Thanks!
Your description exactly matches my issue with a week old Pixel 2. It won't charge using OEM charger below 30% battery. I have to reset the phone, sometimes reboot works but not all the time. Even safe mode won't work done times. It's frustrating.

I'm having charging issues that started when I installed Android P. At times when the phone is plugged in either to wall charger or car charger it indicates it's charging but actually isn't. Only solution I found was to reboot. I should note this only an Android P issue for me, Oreo didn't exhibit this problem. Battery percentage doesn't matter, it could be at 25% or 95% so I'm thinking my issue is just a P beta bug.
Anyone got a solution to this issue?
