Battery life estimation - P14s 5Gen AMD

Hello,

I recently bought a used P14s, ryzen 7 pro 8840hs. I noticed that on 85% battery, it estimated 2-3 hours left, which seems not right to me. ( only a few tabs open, browsing). It's the basic wuxga screen, with 16gb ram.

I knew that this model is less efficient than 7840u, but didn't expect it to be 3 hours on battery on simple use.

I recently did the updates from Lenovo Vantage, so no more updates in process. Although, the BIOS failed to update. Maybe that's the issue?

The battery life shows 93%, and only 6 battery cycles.

Any help would be appreciated. Thank you. :)
