MBP 16" 2021 only charge iPhone 13 Pro at 500 mA

Hi

I have both 14" and 16" model.
I noticed that it only charges my iPhone 13 Pro at 500 mA, instead of 2,400 mA (or higher) as it usually does on my iMac.

The MBPs are plugged in, and I'm using original USB-C to Lightning cable.
And the weirdest part is that it charge my iPhone 7 at 1,500 mA with the same cable, which is understandable since iPhone 7 only support 12W charging.

Anyone experiencing the same?
