What I’m missunderstanding about my vaper?

Hello. I'm pretty new in this world (trying to quit smoking). I have bought recently a Vaporesso Swag PX80. The thing is that if I use the VW mode and I set (p.e.) 45W on a 0.3 resistance, it gives me 3.7 volts. Also, if I set 80W, it also gives me 3.7 volts. The battery is a Sony VTC6 and I checked with a multimeter that it reaches 4.1V. Also, if I use VV mode, the wattage doesn't increases if I change from 3.7V to 4V.

What is happening. Is a security system or something like that? Thanks!…
