Read on... before you just see the post and start flaming.
Been having a helluva trouble with my Galaxy Note II since a month now.
It all started a day in April when I was on a weekend break and my charger just stopped working. Not the charger, but the charger port. I even tried a few other chargers and none of them worked, whereas my charger worked on other phones.
So after the weekend without a phone I come back home and read some posts on XDA about moisture in the USB port. I blow dry the port with the hair dryer and things start working again. After a couple of days of flawless working, again the problem comes up. But it is nothing that a few 'frustrating' 20 minutes of fidgeting will not solve and so goes life.
There have been a few days where it has gotten so annoying that the phone simply wont charge no matter what I do and which angle I place the phone (yoga for phones, anyone?). The phone has even switched off completely at times. Yesterday was one of those days when it simply wouldn't charge.
So again I spend a lot of time on XDA and Google and what makes consensus is that there is moisture in the USB port, or there is something wrong (loose connection) with the USB port and it needs repair.
Few facts before we get to that, and my point about this being a software problem.
1. The charger, when it works, works flawlessly irrespective of whether it is on the table or hanging by the charger from the power outlet. I expect that in case there is a loose connection, the position becomes very delicate.
2. The charger, when it works after moving the wire around for a while, keeps disconnecting occasionally even though it has been placed on a stable table surface and no one is disturbing the table. After some seconds, it connects back automatically and begins charging.
2. The phone works without any problem whatsoever when I plug it into the Samsung car charger - never once do I remember it not working
Now here are my findings from yesterday after I almost broke the phone in frustration.
1. On a whim, I decided to do a factory reset of my device. After fidgeting with the phone for 4-5 hours and it not charging, it magically started charging after the factory reset.
2. After the reset and a 1 hour charge, I updated all the default software on the phone - including 1 samsung update, 1 allshare update, and 1 push service update. Within a few minutes of this update, the charger started showing the 'loose connection' problems again. I also noticed that at times the phone screen would switch on for no reason - for only 2-3 seconds.
3. Again I reset the phone, and force stopped some samsung services and disabled as many samsung services as I could and I could notice consistent charging.
I subsequently installed some apps (not going full out as I want to observe the behaviour) and occasionally the charging stops. I then go into the application manager and shut down some samsung services and more often than not the charging starts working.
After all this circus, I believe there is something wrong with the Samsung services, the phone device drivers, or the MTP service. It does something when it detects a cable being inserted and causes a malfunction of the phone. This is what it looks like to me.
In fact the same problem happens when I plug in the phone to the PC too. The connection keeps breaking and the phone is just not usable from the PC. However the interesting thing is that when the USB / MTP breaks, the charge is still working and the orange light is glowing.
So, finally the XDA relevant question. Can you guys help me find out if it really is a software problem or just some strange co-incidence? Are there any traces that I can pull out to see which app/service is causing the problem? There are many apps/services that I would like to disable, but they are greyed out - is there anything that I can do about them?
Mind you that my phone is not rooted - so all the usually available apps might not work for me. I use the phone as a corporate device and I can't violate rules by rooting the phone.
Any tips, suggestions, ideas, flames?
Hi I'm having the exact same symptoms as you I wondering if you got to the bottom of the problem? Many thanks

My wife has same problem with her note 2 since yesterday. I'll test and share the result.

Are you sure it's not the cable? Because many stock cables tend to be crappy, just try another one if you haven't. It doesn't have to be just loose connection.
Works here fine without issues, so doubt it's software. I rooted mine almost immediately, so can't say much about that though.
Ive tried 3 different cables and every time I plug one in s voice launches lol

Could be a problem with newer Samsung phones and their construction. I have a friend who has a Galaxy S3 (not Note 2) who's gone through FOUR phones so far -- all of them with the same problem of the charging port dying after a while. T-Mobile's insurance company is starting to give him dirty looks, poor guy ...
He gets intermittent charging before the phone stops charging completely. Now his phone is hooked up to the charger constantly while he's at home because of battery issues, so it's possible he's putting excessive strain on the charging port. My thinking is that it's a hardware issue rather than software, but who knows with these things.
mudge
my friend's note 2 having quite similar problem, every time plug in the cable, the phone start charging after some minutes. not the problem of cable, i tested the cable and charger with my phone. Plan to send it to service center.
Sent from my GT-N7100 using xda app-developers app
Exact same problem for N7100 (international version)
I have been facing the exact problem described above. The service center has blamed water logging to be the issue. But seriously doubt it since the port seems to be working fine when it really functions. Also i noticed that when i restart my phone few times it starts to work fine(without me touching the charger cable or the charger itself). I guess its a lot to do with the software than the hardware
note 2 Gt-n7105 bootloops, with charger doesnt boot loop
Hi,
My note 2 seems to work perfectly fine when i connect my charger. But when I disconnect the charger when its full charge it turns off.
When I turn the phone on without the charger it comes on the screen where it shows the "samsung galaxy note 2 gt-n7105" its begins to boot loop.
Can someone please give me some solutions.
Has anyone ever solve this? I have the same on my S4....
I too have the exact problem of phone getting connected and then disconnected automatically in few minutes.
I fixed mine with the same issue
Power usage
Hi,
I first saw this when I was using my sat nav app in the car, I turned off the Performance optimised when plugged in option in favour of a lower power option and the problem went away. As I get more applications on my phone I see this more and more.
Could this be the power usage of the phone? The charge will supply 500ma, if the phone is already using a good portion of that the battery will not charge, so the phone shows the charge intermittently as the phone uses slightly more and slightly less power when the cpu, etc wakes and sleeps. More apps running uses more time on the cpu so more power. And of course as the battery gets older this would display itself more.
Just an idea based on what I've seen...
My Note 5 just started doing this, and only on the car charger using the Adaptive Fast Charge port. Charges for 2 seconds, off for 2 seconds, charges for 2 seconds. Using the normal port it charges fine, just slower. I have the Adaptive Fast Charge adapter at home and in the car, it works fine at home.
usb A3 usb issues
for mine it is intermittently not being recognised in file manager and also charging and then not charging round and round making beeping noises. This started when I dropped it partially in a bowl of oxtail soup. At the time it wouldn't recognise any cable at all. After I cleaned it with a cotton wool bud it was working again for ages but every now and then it wouldn't be explorable in windows. Now its acting up again, very difficult to get it to detect in windows, it starts charging when I plug in the cable but not in file explorer.
It's a real pain because its a samsung a3 which is difficult to open. I think really I will have to get it repaired - opened up and cleaned inside properly or have the usb port replaced.
I've watched many videos about mtp drivers and cleaning and bending the usb port a bit etc etc for many of you I think cleaning the port and/or bending the usb tab a bit would help, good luck.
Stop posting your damn problems so some one can answer it. Jesus look at the posts and see if there is an answer.l cuz you asking makes no difference because u have to scroll to the bottom to see an answer any ways. So just w8. Also ya it's software thing.... Samsung kinda sucks but what the hay I love them anyway even tho thay, including the expencive ones, are crap
I just bought a used SM-T800. I didn't see any immediate issues but I've noticed it has been intermittently powering off or rebooting on it's own. These aren't graceful shutdowns, it powers off immediately, either when I'm using it or I'm not touching it. It can even happen while the battery is supposedly full and the charger is plugged in. This can happen many times in a row, a lot of times during the bootup process. If I leave the cable unplugged I've noticed if it finishes booting the battery can sometimes claim to be almost dead at like 3% when I thought it was 100% full.
I've done a bit of searching and saw a reference to an issue with a cracked interface to the battery. Is there a known issue with this device regarding this? Any detailed links on this? My alternative was to buy and replace the battery. Anyone else having the same issue?

Yes, I've seen that happen with the video glitching but it doesn't happen all the time.
Currently my device won't boot up anymore. Even with the device plugged in, the surge of power it needs to boot up isn't available from the battery.

As was mine a couple weeks ago, i tried everything...rooting flashing re partitioning, you name it, i did it. NOTHING WORKED!!
Until 2 days ago i opened up the back and noticed that the piece where the battery wire connects to the motherboard was loose i simply placed some foil above it and closed it up again( the foil put pressure on the connection which allowed it to carry power across). And now everything works fine, while its not a permanent solution(ill take it to samsung sometime later this month) it does work and now my tab is fully functional. While i dont know your situation this worked for me so maybe it will work for you...Let me know how it goes!!!!!
Dead phone -It would be good to know if this is a widespread issue with Oneplus 3. Symptoms are the phone does not show any signs of activity when it is powered-down and it is put on charge. No screen display or LED. The phone then does not respond when trying to power-up again. It appears dead.
I have had this happen three times. The first time Oneplus replaced the phone. The second time Oneplus support said to connect the phone to a PC USB port with the charger lead, and hold down the power button and volume control together. After 90 seconds or so, the phone did restart.
So when it happened a third time, I knew what to do to restart the phone. But Oneplus seem uninterested in what is causing this problem. I asked them, and their only suggestion is to reset the phone or send it back for repair. Since it has now happened on two Oneplus 3 phones, it is unlikely to be something only to do with my current phone.
If others have had this problem or a any issue with a seemingly dead phone please reply. Then perhaps then Oneplus will take it seriously.
@nottheusualtoday
This is the first post where this issue is reported, AFAIK. So if both your original phone and the replacement are having the identical issue, I think that the problem may be with your setup or the apps that you have.
You can factory reset the phone and run it without installing any other apps or changing any settings and see whether the issue recurs.
Could it be to do with charging & powering down?
I don't want to do a complete reset again. When I got the replacement phone I started afresh and still have had the problem twice. I have seen one other mention of this problem
on XDA. I have looked through all the apps I have installed and
most are very common and unlikely to be the cause. Many other Oneplus 3 users must be using the same apps.
I sometimes have connected the charger while
the phone is in the middle of powering down, and
wonder if this could cause the problem.

I have done this on other phones without any issues but not tried it on OP3.
Charger? Still the same that came with the device?
Trying to replicate
I will try and replicate my hunch about connecting powering
down phone to charger being the cause of the problem.
I don't know what happened, but my true friend is probably deadly ill and she's dying.
My Samsung Galaxy Tab S 10.5 after almost 3.5 years of really hard work, 8h daily of SOT, hard CPU tasks, loading battery two times a day, started to do strange random reboots.
I was installing Blue Filter app, reading big pdf and sending this PDF from Xodo to Voice Aloud reader. Tablet was connected to charger from Moto X Style, which is turbo power charger. I saw first reboot, then other and next. Entered Cwn Twrp, cleaned cache but the problem still existed. Cleaned system, internal storage and tried to flash Iron ROM again. Strange, but tablet couldn't flash Iron ROM 3.2 gauge showed 100%, almost after beginning of installing ROM. I decided to flash 4 elements repair ROM with Odin, but it didn't help. Checked erase NAND, flashed correct pit file.
Strange, but while flashing with Odin, there were no reboots, so downloading mode is working properly. But after install, reboots returned, almost after running system first time.
Maybe it depends on ROM version? I flashed 4 files of 4.4.2 with Odin, while I was on 6.0.1 earlier?
But reboots started on proper ROM.
Also, maybe charger is responsible? Moto X Style 3A charger maybe damaged memory or motherboard of my friend?
Do you think that exchanging the battery may help? My battery when it was loading frequently showed a red cross, it can be that it's damaged, but random reboots never happened to me.
I don't want to buy new device, it's really stupid for me to spend hundreds of dollars every two, there years. I believe that a device should work 5 years or longer. Maybe corporations make devices especially to die after warranty period?
Can you help me to determine what is damaged?
It was my true friend, carrying tons of books with a thin device, reading big pdfs smoothly, making notes tons of paintings, editing photos and taking photos with my Nikon D610 via USB, listening to music with A.r.i.s.e , watching photography tutorials and movies, modern Combat 4 tons of hours, notes, showing portfolio to my clients... Yes I love my small friend, can you help me to rescue it?
You can see the behaviour here
Are the reboots happening even while plugged in or only after unplugging the charging cable?
Also is the percentage reading being sporadic meaning it changes every time it shuts off?
Replacing the battery is fairly cheap and easy on this model.
Here is a guide:

Where to buy a replacement battery:

If for some reason it still has the same issue after replacing battery then the battery connector needs to be looked at under microscope. It may have a loose connection to the board meaning it would need to be resoldered.
Dear Benjamen, thanks for your help. Tab reboots even if it's plugged to charger. The percentage is strange, one time it shows 40%, another time beeps and shows low power warning.
Sometimes it works 5 minutes without reboot, some times boots many times continuously.
Do you think it's battery? No EMMC error or some chip damaged on motherboard?
Download mode Odin worked good, also CWRP worked without reboots.
Maybe internal storage is damaged?
What do you think?
If it is battery I can surely exchange it like you wrote.
You can see the behaviour of tablet on YouTube I've posted above.
Have you tried to reinstall Twrp and a custom rom besides Iron Rom and doing a clean flash? Also I was thinking it might be a corrupted sd card try to remove the sd card and reboot see if that works I had a tablet once that was going bonkers cause the sd card was messed up , it might not be it but could always try it. Also make sure your on the proper boot loader for the rom you are trying to flash iron rom thread actually has a link to all the current boot loaders if i remember correctly. I do own this device and run a custom nougat rom no issues, just shooting out some ideas but you are right this is great device and should last a long time.

Sounds like battery connector has loose soldering. Take it to a reputable repair shop that does soldering and tell them to check the battery connector and see if it needs resoldering. That's how I ended up fixing it with the same symptoms that you had.
Edit: Forgot to tell you but I cant play the YouTube video, maybe the embedded video link is invalid so can you send me the youtube link?
Mine has been doing the exact same thing for a couple of days now.
I'm running LineageOS 14.1.
Random reboots both with the charger connected and disconnected, Battery percentage is around 45% most of the time, but jumps to 0% or 100%.
I've already replaced the battery with a "new" one (about 12 months old, according to the label), but to no avail.
Any ideas? I really like this device and would not want to buy a replacement...

My SM-T800 started doing something strange like this yesterday. As I was watching Youtube and reading a news site in split screen mode, the screen suddenly went blank (it didn't shut down, but went blank at once). Before this happened, I saw a warning that my battery charge was below 15%. After powering on the tablet, my charge was 28%. I opened youtube and a web browser again, and the screen went blank within a minute. After powering on, I decided that I will not be using split screen mode again, but the screen eventually went blank. I monitored the CPU temperature and it didn't seem like it was running too warm (50ish C). I will try re-calibrating the battery (if that's even possible) and even replacing one, but if that doesn't help I guess it's time to move on to something new. Sadly, four years after the T800, nobody made a worthy replacement (the leaked Tab S4 specs look good, but they want to charge laptop prices for that).
PS: It's running the stock rooted (later unrooted) MM 6.0.1 from November 2016 with TWRP.
I re-calibrated battery and the tablet seems to be working fine so far.

Okay first of all very big thank you for your replies
my Galaxy Tab S 1 except strange reboots is also overheating when it has some tasks to do measured temperature on CPU cores is getting around 80 degrees Celsius and is going up and then tablet gets restart so I don't know if it is only the problem with battery maybe it's connected with CPU problems or other electrical problems on MotherBoard.
It's worth to mention, that I've charged the tab with charger from Moto X Style, that is Turbo Charger, with 3A, and the Tab S1 can load with 2A only.

Here's the link to movie with Tab behaviour again, can you see it now?

My tablet used to have a damaged main-board that used to overheat. However, the screen did not go blank when that happened. I actually got some kind of message that said that the tablet is overheating. This was fixed after I replaced the mainboard. You can certainly try it, but these things were not cheap when I did it.
Mine also started doing this last month now it wont power on but resets till the battery is dead.
Did you get it fixed?

I'm seeing random shutdowns with no warning popup on heat but the screen area where the motherboard is sure gets hot. I replaced the battery and same result. I looked at the battery connector and looks OK, seems tight but I didn't check with a magnifying glass. Where did you source your motherboard?
Also how has everyone elese resolved this? I see people citing the problem on this old thread but I'm curioius if you found a resolution.
My redmi note 8 is restarting continuously. Whenever I try to power on the device it is turning off when the MIUI logo lights up. And this will go on a loop like 4-5 times like restarting and then turning off. But when I power on the device when it is plugged in it will work like normal. But when I try to play any sound on it again it will turn off. I can play a video without sound when the device is plugged in but if I try to increase the volume, the device will power ooff again. Can anyone suggest me a method to resolve this issue ?
Battery issue.

It's as the hmd said, battery issue. Get your battery checked asap, because I had the similar issue, and when I replaced my battery I found out the old battery had became too loose like jelly. The servicing guy even said that it was good that I changed the battery then because it could have exploded. So don't delay it and do something about it. Damaged battery can be dangerous.
Sorry to bump up this thread, I've some questions, did you already replace your battery? Currently facing the same issue, and I'm sure its 99.8% battery fault. Unfortunately I can't replace it right away. The question is, do you remember yours charging speed before? I notice my quickcharge doesn't really work, which is good i guess, before my battery getting really bad, I rarely get over 10w anymore, and its just keep dropping, getting stable at 6-7w, right now its only charge at 3.5w. I just want to make sure its only battery/bms problem, not some ICs fault.

that's normal. Your battery's health is not good so I guess it can't handle the fast charging speeds. My phone's charging had also became inconsistent when my battery was damaged. sometimes it was charging very slow and at times very fast.
