negative wireless charging? - Samsung Galaxy S8 Questions and Answers

My wireless charging stopped working randomly yesterday.
I did a factory reset and the phone now recognizes the charger, and says "fast wireless charging"
The only problem it is draining the battery. The battery does get warm.
Samsung told me to mail it back to them, but is this a software issue ?
I'm fully stock att version 950U
Thanks

Have you tried a different charger and cable? If so and you've done a factory reset, then it sounds like a hardware issue

Have you tried turning it off and on again?

Display keeps turning on while charging

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?
Bill
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.

Wireless Charging issue after latest security update

Has there been anyone else experiencing an issue with the wireless charger since the last security update.
Now instead of charging the phone like it did before, it just holds it at the level it is at.
Anyone know why this is happening now, and how to fix so it charges?
Thanks.
You have gone to the menu item fast wireless charging?
Same Issue

Any Updates?
Hey, do the downgrade to PE1 with full wip, and put 100%, your working fast charging. Good luck. To me it helped.
I'm on PH7 and wireless charging works fine for me.
Wireless charging has never been an issue for me with any update. Might be purely coincidental, but you can also try a factory reset incase a setting or system file got skewed.
Have you checked the charger with another phone, or another charger with your Edge. It's possible the charger coincidentally failed at the same time.
My USB fast charging doesn't work. Wireless charging works faster than USB with different fast chargers. I have tried 6 of them and still not getting fast USB charging anymore. It is checked to fast charge also. All happened after the PJ3 update.,
Have you tried different cables, too? If the original charger and cable don't fast charge your phone, it's probably time for warranty service.

S5 Wireless Charger stopping at 70%

Hi all,
I just picked up a generic wireless charger and a Cheotech charging pad and having a weird problem. The phone refuses to charge past 70% on the wireless charger. It does charge to 100% plugged in.
I'm using the latest 6.01 stock Samsung rom. I want to think this is a software thing as it refuses to go past 70% on or off. I have tried clearing the cache but nothing. Any possible easy fixes?

Battery not charging when on/Charging super slow

Hey guys I have a sprint variant and my phone does not charge (USB) when it is switched on wireless charging works but very slow and the phone gets super hot while charging wirelessly. Phone takes around 8 hours to charge
When i switch off the phone phone does charge via USB however it is very slow and with the wireless fast charger it gets very hot. Will a factory reset/wipe solve the issue?
Hard to know for sure. If it's a software issue, then yes a reset should solve it. But if it's a hardware failure, no.
Before doing a factory reset, you might try booting into recovery and clearing cache. I wouldn't expect that to work, but it's easy to do and won't hurt anything.

Newest April Security Firmware Update Broke Fast Charge

Hello everyone,
After a long discussion with Samsung and absolutely no help I have ended up here. I recently updated my firmware on my Galaxy S8 Unlocked SM- G950U(Sprint Network) to the latest build G950USQU2CRC5. After this update I can no longer charge my phone and have fast charging. This is with original cable and charger as well as other cables and QC 3.0 compatible charger. Interesting enough when I plug into my QC 3.0 power brick it tells me that the phone is pulling 5v 1.5amps (7.5w) when it normally says 9v 2amps (18w). Also, only my QC 3.0 compatible car charger will make it fast charge . WTF is going on? I have already gone through settings, soft reset and also cleared cache. Nothing seems to fix this problem. I also get (Slow Charging ) notification at times. Does anyone know a workaround or a fix? Is anyone else experiencing this same issue? I have called and alerted Samsung of this issue. Please help if you can.

I seem to be having the same issues won't charge at all with the Samsung fast charger but it will charge in the car and my USB outlet and a Chromecast charger. Updated this morning to the latest firmware, also unlocked gs8

Okay so what I have found out is even with the cable and a few setting changes it will occasionally say it is fast charging however it never pulls more than 5v which defeats the purpose of quick charge.
Disgusted...
Same here; disgusted with the entire issue... Pay good money, longtime loyal customer, trust now eroded... Even went through reformatting the phone, did not help; waste of time... Thinking of switching to iPhone...
It's the cable and/or power brick. Also we're still on march secuirity, Sammy ain't that fast.
I have the same problem, when I upgraded from android 7 to 9, I lost the fast charge, I'm trying to find a solution.
the usb port says it is wet.
when the cell phone is turned off it is constantly informing that it is wet and the phone is trembling.
when it is on, it charges, however in a normal way, without the fast charge
solved.
