iPad Air 4 Charging speed & time

I have observed that my iPad Air 4 has been charging at a very slow rate after the iPadOS 15.2 update. After trying all the force restart and soft reset things, I noted down the time taken to charge it from 10% to 100%. Below is the log. It takes roughly around 2.25 hrs to fully charge itself. Could someone with iPad Air 4 confirm if it’s as expected or there is any issue?
