What have you been driving it hard with?
When I first got it and set it up, I had it downloading my entire iCloud data (photos, multiple email accounts, etc) while also downloading Xcode, Scrivener, Affinity Designer, Omnigraffle, etc.
I built and ran some of my personal Xcode projects, including one that does multi image slicing/transforms.
I opened a complex affinity designer artboard and worked on it for 20 minutes.
I did some real work, researching a topic I’m writing about, using google scholar to find dozens of articles, downloaded the PDFs, dropped them into my scrivener project and wrote about 3000 words in my research, including some number crunching in excel.
In short, real-world usage, not benchmarks, and certainly nothing to do with video editing.
It’s worth noting that that same amount of work (Xcode builds, affinity designer, 40+ Safari tabs open, some on google apps) would have had my intel 2017 MBP’s fans spinning hard and the chassis uncomfortably hot.
On my M2 Air, the laptop was resting on my bare legs the whole time and barely warmer than my skin.
