The problem with arguing about battery life this way is that it's highly dependent on usage patterns.
For example I would be surprised if there is any laptop, which is sufficiently fast for my usage, and it's battery life is more than 2-3 hours top. Heck, I have several laptops and all of them dies in one-one and a half hours. But of course, I never optimized for battery life, so who knows. So in my case, all of them are lying equally. I don't even check battery life for 15 years now. It's a useless metric for me, because all of them are shit.
But of course for people who don't need to use VMs, run several "micro"services at once, have constant internet transfer and have 5+ Intellij project open at the same time which caching several millions LOC, while gazillion web pages are open, maybe there is a difference, for me it doesn't matter whether it's one or one and a half hours.
You should try a MacBook Pro someday. It would still last all day with that workload. I had an XPS at work and it would last 1.5 hrs. My Apple laptop with the same workload lasts 6-8 hours easily. I never undocked the dell because of the performance issues. I undock the mac all the time because I can trust it to last.
Nothing too crazy I don't think. A bunch of standard Electron applications, a browser, a terminal - that's pretty much it. Sometimes Dockers, but I always kill it when I'm done.
