You're looking at an inadequate metric--the real question is what is the battery capacity on the 12.9 compared with the MacBook.
So the 12.9 iPad battery (largest iPad battery) has a capacity of 36.71 watt-hours.
The latest 13" MacBook Pro has a capacity of 58.2 watt-hours.
So the MBP has 50% more battery capacity. If the energy consumption drops to iPad levels, you're looking at 15 hours, as opposed to 10 hours. It might be even better than that if the CPU is passively cooled, eliminated the need for a heatsink and fan. That could allow the batter to be bigger.
Conversely, you could make the battery smaller and thus make the MBP smaller, while keeping the same 10 hour battery life.....

Where is the "amazing battery life" going to come from? 2020 10.2" iPad and 12.9" iPad Pro are rated at 10 hours. This is pretty much identical to the 11" and 13" MBA models.
