There are many Windows based pc getting basically the same as the M1 in battery life.
I disagree look at this video by Linus. Before you say it's an "Apple Centric channel", Linus Tech Tips does not lick Apple's ass.
The MacBook Pro M1 got 22 hrs in the video playback test. Video starts at battery test.
Honestly the MacBooks should win the list. All the laptops above it lack Retina display and they only last a few minutes longer.
Top laptops of this year.
For work or play, here are the laptops with the best battery life

Last year's Latitude 7400 2-in-1 was already excellent, so why mess with a good thing? The Latitude 9410 2-in-1 doesn't bring anything new from a visual standpoint, but some users might appreciate the newer Comet Lake-U CPU options and Wi-Fi 6 connectivity.

The number 4 is
4. Apple MacBook Pro (13-inch, M1, 2020)
16:32
SPECIFICATIONS
Display: 13.3-inch, 2560-by-1600p
CPU: Apple M1 CPU
Weight: 3 pounds
battery size: 58mah
The MBP M1 laptop has a 2560-by-1600p display and not a measly 1080p and has the smallest battery size 58mah compared to the laptops mentions above.
What if the M1 MBP had a 1080p and a 78mah battery? it would have MUCH higher battery life compared to the laptops above.

Ahhhh the ole move the goal posts defence.
Nope all I am stating are facts. The laptops in list that are top 3 have 1080p displays and have a MUCH bigger battery capacity than M1 MBP 13" which has a 2560-by-1600p display and a 58mah battery.
If the 16" MBP had the M1 and with it's 99mah battery it would easily have the best battery life of any laptop even with a 3072‑by‑1920 display.
The M1 is built on TSMC's 5nm node currently that is most efficient node available. After that it is the AMD 5000 series and AMD CPUs are built on the 7nm node.
Also keep in mind macOS Big Sur does not have low power mode. Later this year macOS 12 will be getting low power mode and that will also increase the M1 MBP battery life
