Is it safe to use iPad pro while charging?

Hi! Can I ask what would be considered as heavy works? (Procreate / modeling tools?)

It's okay when you don't do heavy works with your iPad while charging. But if you charge and do heavy works at the same time, your iPad can overheat and this may damage your battery.

It is quite fine to use while charging.

Heavy works like; editing, photoshop, blender, playing high quality games etc.
