I'm having a strange problem with my phone where it won't charge when the screen is turned off. I've been monitoring the charging status with a battery stats logging app, and the charging current drops 0 whenever the screen goes off and then jumps back to normal values when the screen is turned back on. The phone doesn't seem to charge while completely turned off either.
I have tried multiple chargers and cables. The most powerful charger I have access to at the moment is only 1.5a, I hope to try a 2a tablet charger when I get the chance. I have also tried factory resetting the phone as well as switching from CM10.1 to Omnirom, neither of which affected the charging.
Has anyone had similar issues in the past? I find it very strange since a complete wipe and changing roms had no effect, which suggests a hardware problem. However, I don't understand why the charging would stop only when the screen is turned off, that doesn't seem like a hardware issue to me.

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
Has anyone heard of these problems before? The first one is that the back and menu buttons don't work. They don't even light up when its turned on. Second problems is the battery doesn't charge well, I will put it on charge when its turned off and it won't get to the charging animation and for example when its on and shows its charging I pull out the cable and its still showing as charging. Also the percentage of battery left was all over the place sometimes. I turned the phone off, when I turned it back on about (without the charging cable in) it went to the charging screen, so turned off again and on again, this time it started up fine but when got to the home screen its still showing as charging with no cable attached. When I got the phone the battery was completely flat, so he must have had some trouble charging it too (he supplied me with a black 1a charger rather than the white 2a charger they normally come with)
I got this phone off eBay so I am sending it back, it had a new screen put on it apparently they didn't wire up the back and menu button? as for what's causing the charging problem? I noticed there were interference type lines when I used the touchscreen when it was charging. I was able to charge the battery in this phone in my other working S4. There was a OTA rom update but that didn't fix any of the problems, I'm guessing they are hardware problems and not much I can do about them other than send it back?
Solved. The surgery went fine, actually just unplug/replug the battery
and now tablet is charging fine, but only when on. If I turn it off and plug the power cable
I have the onscreen b&w animation of a charging battery but not even 1% increase over the night.
Might consider finding a replacement sooner or later.

Hi every body
My nexus behaves strangely regarding battery charging, I've tried different cables/chargers same result. I've emptied cache, no result.
Actually here's where I am: When the nexus is plugged with original cable+charger, Battery Monitor says plugged, discharging.
The flow shows a negative mA value. I tried charging the tablet while it's turned off, full night.
Sometimes I managed to get a full charge, sometimes only 5% increase during the whole night.
The usb port seems ok, I can plug it on a computer, copy files both ways, speed is ok. But still no charging.
I've read lots of forum posts concerning battery problems with nexus7, my understanding is that I'm facing
a hardware problem, not software. I have to open it and clean/check the link beetween usb port and the battery charging circuit.
Is there something else I can try before trying surgery?
thx
Hi does anyone else have an issue while charging the phone where the display keeps turning on every 10 seconds and then turns itself off?

No. It sounds like a third party app is causing that.
To check, boot into safe mode and try again.
That happens with one of my wireless chargers. I guess when hits 100% then drops and back to 100% Not sure if your using wireless or not.
I was not on a wireless charger, on the other hand I was on my old HTC changer that I have on another room. Was not doing it from what I noticed with the Samsung charger.
*** tried a different HTC charger and it seems to have stopped turning on, wonder if that HTC charger is throwing out different power

Or maybe it's got a short in it. My car charger was doing this on and off this morning. And I can tell the wires going into the base are going bad.

Yes I have this issue! I just bought this phone a week ago. I've been using the fast charger included with it. Every time I charge with the fast charger, no matter if the phone is on or off, the display will turn on and off every 10 seconds or so like it keeps getting disconnected/reconnected from charging. I tried charging my phone with a regular phone charger and the display no longer turns on and off. What's going on?

Yes, been having this issue as well (happened before I rooted). Only happens when I use my old HTC chargers, doesn't happen with the included Samsung fast charger, or a 3rd party wireless charger. Have tried turning off fast charging in Settings, disabling the Stay Awake when charging option, and charging in Safe Mode - makes no difference. Would be great to know what causes it!
Yes I'm having same issue! Only when I use my old HTC charger! Any other one it doesn't do this! Would love to know a resolution!
Its the older chargers, like the HTC, not having sufficient current for the S7s bigger battery.
Probable solution
I had the same issue with my S7. A week after buying it the display kept lighting up randomly during charging. I switched chargers to an older Huawei and the issue went away. Last week the issue came back. I tried blocking apps but it did not work. What worked for me was clearing the USB cache. Settings > Apps > Show system apps > Enabled > Search for USBsettings > Storage > Clear data and cache. PS - This also works if the phone wont charge due to moisture detection.
I had the same issue with my Samsung S7 Edge while charging using one of my dual monitor's USB Port. I just switched to another USB Port and it stopped doing it.
Weshp, thanks for your very specific answer. It seemed like it was working (my phone stayed off for a longer pause), but after about a minute, it started coming on and off again and when I check, there's data in the USBsettings again. If you have any other ideas, I'd love to know.
My Galaxy S7 has been doing this on and off for a long time. I suspect the cause is overheating because the battery is charging too fast. The lower power chargers won't charge as fast so they won't heat up the battery. If I'm wrong, I'd sure like to know how to fix it.
I can't find the path to clearing the cache so I haven't tried that.
Yesterday, my S8 said that there was moisture in the charge port. I look in there and saw that there was something in there, I tried to blow it out several times but managed wipe it out with a handkercheif. After that I swiped the notification and it didn't come back again.
At night time, I plugged my phone to the charger to see that after the phone's screen went off, it stopped charging to come back again when the phone screen turned on. It kept repeating this cycle. But when I unlocked the phone it continued to charge until the phone's screen turned off.
I changed the charger, it charged even when the screen was off. Also, it worked when I tried to use a powerbank. But when I used the packed in charger, it kept repeating the cycle.
Thinking that it might be a bug, I restarted the phone to see it's fixed.
I closed the phone to switch it on this morning. But before I switched it on I plugged the charger to see that it gave the "Drop" icon meaning that there is moisture in the port. Then I switched the phone on. The problem came back! It didn't charge when the phone's screen was off. After I tried to charge it with another charger, I plugged the original charger back. It worked even when the screen was off.
To be sure there wasn't anything stuck in the portI closed the phone, filled the port with water, waited untill its dry and plugged the charger. I stopped giving me the "Drop" icon and started charging the phone.
After that, I turned on the phone and plugged the charger. The problem was fixed!
But "was" fixed... After a while, the problem still persists.
If you can say what might be causing this, thank you!
I think, the problem cause is Fast Charge 2.0
Now I opened the Advanced Battery Options to disable the fast charging, but it turns out that is was already disabled! But wait, it says that its "Fast Charging". To enable it, I unpluged the USB-C. It enabled itself! After plugging the cable back, the problem is solved. At least for the time being.
Some interesting stuff is going on with this phone XD
I got similar problem. After connecting charger phone says fast charging blablabla and after 5 seconds charging is stopped and then after 1 second it charging again but with no fast charging. I've tyied few diferent chargers and cables also i've cleaned usb c port wiith isopropyl alcohole with no luck. Fast charging missing. Restart and switching on/off fast charging performed few times - no luck. Must be a bug in system... any ideas folks??
well i dont have does issues with my s8... but it did once happen that phone didnt want to fast charge but after repluging the cable issue was solved...i would advice u to take ur device to waranty service cuz solving problems on ur own is not acceptable and ur device shouldnt have those issues.
