What is a normal battery life of a 3 Cell 41 Wh

HP Recommended
HP Laptop 15-ef0888ca
Microsoft Windows 10 (64-bit)

I just bought a HP Laptop 15-ef0888ca, AMD Ryzen 5 3450U APU, Radeon Graphics, 8 GB Sodimm DDR4 SDRAM, with a 3 cell 41 Wh battery. I basically use my laptop to play Facebook games and seem to only get 3 hours of battery life per charge. Is this normal, when the advertisement said that the laptop should be good for about 8.5 hours of use. Any information/direction would be greatly appreciated.

That is normal, you can work this out roughly: Machine probably consumes 13W to 15W to drive CPU, Screen (the biggest burner), other parts such as RAM, HDD .... with a 41Wh battery you can see it can only run for around 3hrs
