The Thinkpad T14s 2-in-1 with Intel Core Ultra 5 has great battery life: 10+ hours with moderate usage. I also have the Snapdragon T14s which gets about 14 hours, but I'm still waiting to get full Linux support for this two year old laptop.
Note however, since I've been using my Thinkpad 2-in-1 on battery almost everyday for a year, it is somewhat degraded. upower shows
