Fast charging is gone

[TokedUp]

Anyone know what I have to do to get fast charging back? I have the option enabled in settings. The cord is good, my wife's phone fast charges just fine with it. I've soft reset the phone, cleared cache, and just about any other option I could find on the web. So weird cuz it was working fine not too long ago but just noticed now that I can't get it to work.

Try cleaning the usb port on your phone. i had the same problem, just cleaned it out with air.

Thanks but been tried that. I work in Audio/video so that was one of the first things I tried.

Are you able to mount the phone as storage on a computer, or able to access a USB with the OTG adapter? The charge port on this phone isn't the most robust and a few people have had problems with then failing.

No issues with any other stuff except fast charging. The phone charges fine but just say fast charging and takes forever. It's so weird cuz in my car my phone would barely charge when hooked up to USB in console, but then soon as I lost fast charging at home it started fast charging in the car. I just don't get it

Well luckily normal charging and USB still works so it's not the worst. At least your battery will last a little longer now?

My advice would be install an app like accubattery

https://play.google.com/store/apps/details?id=com.digibites.accubattery

It will show current when charging.

Fast charging being displayed by Android only seems to indicate fast charging is enabled rather than actually occurring.

I find when fast charging is occurring with standard Samsung charger, but not original cable it will show approximately 2800 mA.

It did seem to be below this rate a few months ago when ambient temperatures were higher and battery temp got above 36 °C

I also bought an unbranded charger cable that has an led that illuminates bright when high current charging and dimmer when charging at lower rates.

Probably defective . I've read issues on here about fast charging no longer working and it had to be repaired by samsung.

Ive had this problem with all my samsung phones since galaxy s8. I dont know why after some months the phone loses the ability to fast charge (it happened to my s8, note 8 and currently note 9)

I finally replaced the usb-c port

I had the issue that fast charging was gone and it charged very slow sometimes. I did many searches and did everything I could do. none changed anything. finally I went to Samsung and they replaced the port.

It was. Now I am a bit skeptical about this USB-C port thing. I take good care of my gears. Especially this one that cost me an arm and a leg. I want to do a survey if all the manufacturers' type-c port is prone to get damaged like this easy!

I would take your device to a Samsung Service Centre and let them take a look at it.
