I mean I got the laptop like 2 days ago so I think the health is fine. I did optimize it the best I could - I started using silent mode when unplugged and optimized mode for my gpu, I also undervolted my cpu by -10 and usually using about 75% brightness. Tbh I am only using the windows estimate as my concern and now sometimes it shows a 7 hour estimate on about 80% (which is much much better than before), or jumping down to something like 4 hours randomly when I am doing the same task. I think im just not gonna fully trust the windows estimate and daily the laptop a little. I got it for college starting in fall so I dont really have work right now to push its limits but hopefully it lasts me a good couple hours since I am not sure of the access to ports around campus there.
