[Q] Charging goes on and off, Software to blame?

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

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.

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

T-Mobile D851 LG G3 - Turned off on its own, will not turn on or charge

Hello All,
I have a problem that occurred a few days ago with my LG G3 (apx. 6 months old). My phone has been running fine and out of nowhere, my phone turned off and I couldn't turn it back on. Initially, I thought that the battery may have died because I was using a golf app that utilized gps, but my phone was at a 100% 20 min prior to it turning off. When I got to my car, I plugged it into the charger, but I didn't see the charging light and it still wouldn't turn on. When I got home, I plugged it into the OEM charger for about two hours without any success (the phone felt warm similar to when I charge my phone). I've long pressed the power button, tried the power and lower volume button to hard reboot without any success. I bought this through the t-mobile site like my previous phones through their New2U certified refurbished program which comes with a 90 day warranty (expired).
Has anyone experienced a similar issue and if so, what did you do to correct the issue because T-Mobile referred me to LG so that they can direct me to an authorized retailer. Any assistance would be greatly appreciated.
Note: the phone is in great condition.
Thanks

Have you tried removing the battery, holding down the power button until any residual current is discharged, reinserting the battery, then plugging back in the OEM wall charger?

Any word? Does your pc detect it? Kinda in the same limbo... ?

turning off on its own might be due to overheating

Phone restarts when removed from charger.

Hello, I have a Galaxy Note II sgh-t889. The phone worked perfect until I recently flashed it to Android 6 with cynogen mod. The phone worked fine for a few weeks, now the phone only powers on when connected to a charger. When removed from charged it goes back to the Samsung note II logo screen and won't boot past. I don't think it's a battery issue as I can boot in bios and it shows the battery is %95 full. It will sit on the logo screen until charger is plugged in, then will boot fine to OS. I've factory reset multiple times to no avail. I've read other forums of users who experienced similar issues and have narrowed it down to a possibly corrupt flash. The problem being, when connected to my pc the phone won't boot to home screen, it just sits on the logo screen. (So Odin does not detect the phone) The solution I was told is to flash it back to stock/oem rom. The problem is I can't get it to bboot to home screen when connected to pc, only on wall charger. If someone could please give me some insight, I would be more than grateful. I don't have the money atm to buy a new phone, so my only option is to try and get this fixed. Also I don't have an external sd. Can someone point me in the right direction of what to do ? I'm so stumped and I can't stand having to pack my phone around on the charger all the time...

UCH12

Hello,
Couple of months ago I bought a UCH12 charger and it was working fine with my Z5 Dual Premium.
But since the update to Android 7.0, it stopped working.
I'd plug the charger to the phone and it would vibrate as if it recognized that something was connected but the phone does not show the icon of being in charge and even when I go check the battery usage it says that the phone is not charging.
My phone is not routed. I tried getting help from Sony support, but all of the action tried (reset, long reset, turning on and off, repair, etc...) did not get any results.
Anyone has the same issue ?

have you tried charging ANYTHING else from this charger?
looks like it's dead.

Yep, a Galaxy S7, works like a charm, just hates my cellphone or my cellphone hates it, either way.

try the same chargers while
1. device switched off
2. charging optimization is off
i suspect that charging optimization causing trouble...

1. Same thing
2. I am not sure where to do that, I have check battery optimization but iit only optimize the charge in respect of the apps used. and it did not do anything.
I admit that this is a strange one, has anybody witness the same thing ?
I can always send it for repair (I am still under warranty) but I'd like to use this as last resort (takes some time and forces me to use a crappy phone).

Tried it, no change...
EDIT:
I wonder if this article isn't saying that Google might be messing with Quick Chargers...

Samsung Galaxy A70 charging issues

My Samsung A70 doesn't want to charge at the moment. The last time the charge worked was the previous day. Sometimes it happens to me that my phone suddenly does not charge, in these cases I took it to show it to a phone repair in the city, but when the technician tried to get it to charge it worked, but when I tried it at home no. I also went to the technician again, this time he tried to load it and at first it didn't work, after other attempts he started to load and after trying mine it worked again. I don't think it's the charger that creates problems but the phone, since I tried to charge it with various chargers. What I was also told by the technician is that I have a fast battery charger that my phone can't stand since this charger should be for the Samsung S10, S20 etc... The model is EP-TA800 and searching on google I found that charges at 25W, and still looking at google it says my phone supports 25W. Now I don't understand where the problem is it doesn't want to load again so I try to wait a bit to see if it loads again later. I also noticed one thing, that when I turned it off and then put it on charge (it gave me no sign that it was charging) and then on again, I found that the battery had increased. Could it be that it loads without showing me? Or could it be that my current charger is harming the phone? If you have had similar experiences let me know if there is a solution

It's a common issue on those phones (and on other Samsung devices, I've experienced it too), and to be honest I'm not sure if a repair is even worth it. One common "fix" is to press on the back of the phone, above samsung logo. It usually works, but it's not ideal.

I had random charging issues as well. Had the port changed and still did it. Sat in the drawer for a year and i finally took it somewhere else. They said it was the ribbon that connects the charging port to the board. If that makes any sense. They had one from a junk phone and didnt even charge me for it. Works perfect.
