Ender-3 S1 Pro printbed can't reach 110 degrees

Hello all,
Is it common that the bed gives lower temperature than what you set it to?
I measure with an IR meter and the bed is usually about 10 degrees lower than my setting.
Tried ASA the other day and set the bed to 110 degrees, but max temp I measured was about 93 degrees.
However this was not in an enclosure, but surely the bed should get warmer anyway, right?

Does anyone know the best settings in Manual PID Settings?
I’ve done the Auto PID for the bed, but that made no difference.
Or anything else that can be the cause?

Thanks in advance!

Printer is more or less stock and only about a month in my possession, bought new.
