HP Omnibook Ultra Flip 14 Battery Life Just OK, not Surprising?

I bought an HP Omnibook Ultra Flip 14 with Intel Core Ultra 5 226V (16G+512G version). I've heard very positive comments about the power efficiency of the Intel Core Ultra Series 2 and the Omnibook Ultra Flip laptop specifically as well. But I did not find it very impressive since I started to use it myself. Working on Word documents consumes about 10% battery in an hour, which is fine but not surprising. Web browsing using Edge took about 25% battery in two hours, which is okay. A Zoom call using a headphone with the camera on took 20% battery in an hour. I remember it has been like 20% battery per hour for Zoom video calls since my last laptop and the one before that, like 3-5 years ago. So I cannot say I'm very impressed with the battery life of the Omnibook. It's just not bad. Do other Omnibook Ultra Flip users find it similar?

I'm also not sure if it is related to the specific CPU version. Most reviews I found are on 258V or 256V. But this generation of Core Ultra CPUs has a pretty small difference between the lower and higher ends models. Thus, I thought 226V was a valid option. I also don't see how 226V would need more power than the higher-end models.
