So I have a galaxy S20 ultra and having a problem with it charging wireless in my wireless car charger. At first I thought the charger might be defective or uncompatible with the phone. The charger works fine with my wife's S20+ but not the ultra. Also it works fine when I use both my wireless charger at home. The problem is it would charge then pause then charge then pause every 2 second. I tried turning fast wireless charging off and it still didn't change anything. Any help would be greatly appreciated.
Solved! Go to Solution.
Its blocked intentionally. Only Samsung official pad or certified by Samsung pad will be able to do Wireless Fast charging.
Fast wireless charging will only be enabled on devices that have been certified by Samsung and the Wireless Power Consortium. If you are using a non-Samsung wireless fast charger, check with the manufacturer or WPC homepage for the charger's certifications.

Verifying the same issue with a new S20 FE 5g.
Every time I place it on the wireless charger it reads "Fast Charging" for about 2 seconds and goes back to normal speed. I'm using the same brick and USB cable to power the wireless charger that gives my phone a fast charge when plugged in.
The phone fits perfectly. I have tried it with the case off and the case on still no luck. Tomorrow I will try using the wireless charger on the wife car since its the same as mine. See if there any difference.
Gotta get the actual charger for the s20. My newest wireless charger won't keep up with my s20 unless I close down every app and shut it off otherwise its like using a regular charger and says something along the lines of "this phone uses to much energy to wireless charge" in not so many words. You need to wait for the wireless charger to come out for the s20. The processor is using to much to keep up with the low wattage of your wireless charger.
