I noticed this as of yesterday. My Nexus One is plugged in to the wall charger right now, but it randomly stops charging. The light at the top disappears and the phone shows that it is not charging. Give it a few seconds, and it starts charging again. Sometimes it will charge for 30 minutes without a problem, other times it starts and stops every few minutes. I've tried messing with the cable, but it doesn't affect whether or not it charges. I plan on switching batteries with my brother to see if that has a change. I'll also try a different cable soon. I've already rebooted the device, no change. If you go to the battery usage chart, it shows huge gaps in the green charging area..
Rooted, running geo411m stock rom, Android 2.3.3, stock kernel, stock HBOOT.
Any ideas? I hope the charging circuitry isn't failing. Took like 5 hours to charge, now the phone is at 95% battery.
I would try to wipe the battery stats from recovery see if that makes any difference then maybe try full wipe 1 to 5 times and maybe a clean install or even just change ROMs and check if it's the same.
alright I'll give those a try. I just don't know what could have caused it to happen. been on this rom for months, no change in setup. just randomly started. seems like a software issue to me (hopefully not hardware). even right now as I'm using it, it's plugged in but not charging.. 81%, no charge light.

Your charger or cable are most likely the culprit. When the charger doesn't provide enough current - the phone stops charging, and sometimes chargers fail.

I will also try that. I'll switch chargers with my brother tomorrow.

It was the charger! My brother has an official HTC one he bought off eBay (looks like this), whereas I have the one that came with the N1. His charged my phone fine. My charger was still screwing up with his phone. I'm just going to buy the HTC one now. Thanks for you suggestion!

Call HTC, even if you're out of warranty. They have been exceptional in providing replacements for broken accessories. I had somehow cracked the lens in the battery door, and when I called to ask where I can buy a new back cover they simply asked for my address and told me I could expect one the next day. Worst thing that could happen is they say "no".
I was searching an answer but found myself. The issue is something happen to system because of unstable voltage then keeps turning off charging.
I've added agni control kernel and activated ignore unstable charging power and voila!
I know this is an old thread but can you tell me - if you can remember (!) - how did you acticate "ignore unstable charging power"? I have the AGNI kernel for my Xiaomi Redmi Note 5 but no idea where the settings are! I've heard of an app but where it is I don't know.

How did you activate that feature? Where are the kernel settings?
phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted
l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery
Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

I tried - original cable with original charger 6hr
- original cable with apple charger 2hr
- different cable with original charger 1.30hr
- different cable with apple charger 2hr
(Used different fast chargers too, same results)
I tried a smart switch recovery. Same conclusion which makes me think its a hardware issue

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..

Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.
I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)
I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?
So... any solutions?
Hello Team, any one have got issues with MI MAX2 , as one day it switched off while playing mindcraft game , battery went low, now even if I charge with multiple devices, their is no charging light or if if you hold power button it wont power on. No Mi Logo...
Tried volume up/down combination , tried to connect all the connector's , still same issue..
One thing noticed while charging , the adapter wont heat up , nor any component on the mobile like battery , which was happening in normal working condition
Tried EDL (Emergency Download) , no response on PC device manager.
Please suggest....

I would recommend a very long charging session ( over night ) because if battery switches off caused of low power, it is very slow in recharge.

Any one is having the details for charging circuit on Main board , how to test ?
Same problem here, you got any luck?
Happened 2nd time, first time I connected it to xiaomi power bank and it started charging, but this time no luck with that method
(it could be that it was pure luck/coincidence)

I am unable to find the power IC part number as PCB is bonded with metal cover, I need to remove and check further , I did checked other component with millimeter its fine and getting normal battery voltage, I tried new battery and charging PCB, no luck , no power light on mobile or charger is heating, hence suspecting power IC failure , trying to source it to replace it my self.

I solved my problem...it was software...it seems it (wrongly) detected that battery is totally empty, and entered some kind of "refresh battery" mode.
I used USB voltage/current meter and noticed that it didn't charge at all for 2h (0A), then went through 3 phases: 0.46/0.32/0.13A, and after about 48h
I was able to power it on. Can't tell exactly how long each phase lasted, as I wasn't checking all time

Hey everyone, how y'all doing?
I've got this problem for 2 months now where the charging has been super slow and no idea why. I am using the official charger and cable that came with the phone, I used my wife's s20's charger with same result and a third party charger with 3 different cables with similar results. Accubattery recorded that my phone's battery health is at 86% (3460mah) should I change it and lose my water/splash proof?
Oh yes I have flashed a few different ROMs (currently using Dr Ketan) with the same results except for evolution ROM, with the aosp ROM I was able to charge my phone from 14 percent to 100 in 90 minutes which is kinda weird...
Any advice would really help thank you

Get yourself one of those 2$ USB doctors. It will tell you how much power the phone is taking in. i.e. Fast charge should be 9 volts at about .8 amps and slow charge 5 volts at 1.5+ Amps.
Make sure your port is clean and moisture levels are low i.e should be below 80%.
I had this problem once when moisture was over 80%. It then went away. But at that time the phone will warn you about the extra moisture. It will say Moisture detected in USB port Fast Charging disabled.
The second time this happened was after the update to android 10. Had slow charging and overheating and audio acting up but that went away after re-setting the phone a few times and clearing cache.
The latest update to Android 10 seems to be causing a lot of issues with Display, Audio and overheating / slow charging. My audio chip finally stopped working. And the phone is now with Samsung.
My 2 cents if you see overheating and slow charging. Stop using the phone while its still working and take it to Samsung. Because if you continue to use it something will fail. And Samsung will want to give you a big fat bill to change it.

Thanks for the advice and I'll see to it. It's just yeah it seems like after android 10 things have been degraded
So apparently turning off fast charging in options gives me a faster charge time. With fast charge on it takes from 7% to 100% in 3 and a half hours and with fast charge off it takes 2 hours only.... Maybe my fast charging "chip" / "module" is broke?

Unless you see something in there I do not advise poking around inside.
I suspect your problem is that the Samsung USB cable packed up. And your trying with all kinds of cables and chargers. Go to a Samsung Store and ask them to check with a Samsung Cable and Charger.
I went thru this circus a few months back.
The only solution is to get a Samsung Charger with a Samsung Cable.
Then make sure fast charge is on. For wireless and wired charging. Wipe your cache and you should be ok.
I have seen way too many damaged USB ports from people trying to clean it. When there was nothing in there to start with. Use compressed air. If you see something in there.
So my note 9 (snapdragon) is never using fast charging and even if i manage to get it to give me fast charging it gives 1 hour 39 minutes to charge and takes 3 hours, when i charge by cable charging with disabling the fast charging setting it charges in 2 hours 10 minutes while it is cable charging not giving me fast, with the setting enabled it charges in 1 hour 59 minutes.
One side of the type-c never gives fast charging and the other side writes fast charging for 4-5 seconds then switch to cable charging and rarely doesn't switch but the charging time is 3 hours as i mentioned.
I tried everything possible other than trying to flash another software it is with the stock but unlocked.
I cleaned the socket, used 10 different chargers with different cables, wiped cache and tried safe mode and more.
Sorry for making it a long post but this problem is driving me crazy and i want to know can it be software issue not hardware because the phone is used for 2 months and the socket can't be cleaner, and if i flash the stock rom again will it be locked by T-mobile and i would need to unlock it again?
Thanks alot.
First of all, try to change the cable that 98% of the time is the problem when having these types of issues . Then consider the fact that the battery's temp influences the time needed for charging so if it's hot, software will decrease power in charging so that will give a longer time to charge. Even using the phone while charging or leaving apps in background will extend time for charging.
I have posted this so many times.
Samsung uses cheap USBc connectors that short out. Once you lose FC the only way to get it back is so get a new USBc installed by Samsung or a third party. This happened to me about 4 months after I got phone. I never fixed but I will never buy Sammy again. Its not your cables, its not the power cube, its the connector on the actual phone.

In every case, better Sammy's phone USB c connector then iPhones phone lightning connector because after a year you can't even charge the phone at all for having intermittent false contacts when you plug in the cable for the phones connector going bad....

It's possible the the USB C connection is faulty, it's also possible it's a faulty charger cable or even a faulty charger .
Eliminate one by one, buy a good USB C cable to check if that cures the problem, it often does.
Whilst as Tokedup says it may be the usb socket in the phone as according to his post he didn't fix the problem it's not possible to conclusively determine the cause.
It's unlikely to be caused by software, but high ambient or high battery temperature will lead to charge rate reduction
Maybe try an app like accubattery, this will show the charge rate in mA.
With a genuine charger and cable fast charge will reach a maximum of 2800mA

The problem is the phone isn't fast charging at all.
I believe it's the phone socket actually.

I already tried alot of cables and chargers so i am sure it's not one of them and now i am nearly certain it's the socket since you said it's unlikely to be a software issue, but i really wanted to know what could've caused it because i am sure i didn't do anything wrong.
I have been monitoring accubattery for a month now everytime i charge the phone. The mA is always between 800-1200mA and the phone takes nearly 2 hours to charge.
Thanks alot mate
just to be sure that it is not software related, remove all the battery optimization related 3rd party apps. clear cache and test the phone with stock usb cable and charger that came with the phone. what i had experience is that my note 9 SM-960F is sencitive to charger. if i use a third party fast charger or cable, it give me some sort of trouble like overheating or slow charging. so make sure you are using stock charger and cable that came with phone.

Why not get a Samsung wireless quick-charger and try it?
A wireless charger will not be faster than cable charge but I would get one so you don't wear out that port to where it doesn't interface with a computer if needed in the future. Btw all my new phones thats the first thing I turn off is fast charging it degrades battery more over time.

When I purchased my note 9 I did a post somewhere where I said the weakest link in this phone is the Charging port. And so right from the first week I got a wireless charging pad.
Also during the rainy season I keeps saying there is moisture in the port. Basiclly god help you if you live in a place with high humidity.
Like you this is the last Samsung Note I will buy in this life. My Audio packed up after the update. I suspect the over heating caused this. And their support is outsourced in India so they don't give a hoot about your issues.
To the OP.
Try a wireless charger if that fast charges Then you know its a port issue. If that also does not fast charge then its a chip / board issue.
I predict all note 9 users are going to see more and more problems as the over heating causes components to start to fail.
You can get a new USB port with flex cable for like 4$ on ali express go for it.
