as an owner of a Legion Pro 5i equipped with 275hx and 5070ti. This laptop is a amazing gaming machine, but the battery life is hot garbage. When unplug, it became a stuttering mess, Even running VSCode would have frequent stutters (SSH to another machine). It would last about 3 hours with dGPU disabled, and 1 hours with dGPU driving the display. (Which is my main problem really, cuz everytime advanced optimus switched the display it would enable HDR, and I hate HDR (im not gonna get into why), and I use 170w power adapter in the office (300w at home) and it would disable the dGPU unless I select the dGPU mode, so it forced me to use dGPU mode all the time. (Restarting to switch the mode would be a hustle (restarting apps, stuff)) So in my everyday usages it would last me 1 hour or less.

In laptop, you need low thermal, not performance, intel did it better with low thermal in same performance.
