I can confirm that various Dell XPS 15 models and Microsoft Surface Book 2 and 3 models are just not usable without the power plug for my software development (and very rare gaming) needs. I also need the power plug for a simple thing like a Microsoft Teams meeting that last longer than one hour.
Compare that to my MacBook Air M1 which runs for a full day easily. Also, standby works.
With Dell I learned it's better to always shut down.
