You're actually right. MacBook Air M1: 49.9Wh | MacBook Pro 16" 2019: 100Wh The 16" MacBook Pro is rumored to have double the performance CPU cores, and either double or 4x the GPU cores. So for tasks that are strictly GPU bound, battery life could be about half of the M1 Air. Considering that this is the absolute worst case scenario battery life (assuming of course that they don't make the battery smaller), the new 16" Pro is looking pretty exciting.
