I recently bought an “Asus TUF Gamming F15 FX506HF” laptop and when was doing the research before I bought it, from the info I gathered I expected at least 4 hours according to what I regularly do.

however, what I actually get (on battery safer mode) is max 1.5h-2h, just watching YouTube on Chrome

NOTE: I am sure I do not have any heavy background processes or something as the OS is still completely fresh and I also removed all the bloatware and unneeded garbage.

​

So, is this normal and is what I should’ve expected or there is something wrong and I must return it while I still can?
