Ultra S21 extremely slow wireless charging

[anon(400316)]

I had the S20 Plus previously and fast wireless charging would work normal with my Samsung wireless charger. I recently purchased the S21 Ultra and the wireless charging is way slower on the same Samsung wireless charger. For example, my S21 Ultra last night went from 15% to 52% over a period of 8 hours, where the S20 would've been at 100% in half that time. Is this a known issue with the S21's, or do I need to take my phone in for service?

are you using the same charger as the s20? If you have a case, take it off and see if it is faster.

Is your device displaying "Fast Charging" when on the charger?

If a Samsung charger it shouldn't be affected, but who knows especially if it may be an older charger. Key is to see "Fast Charging" displayed.
