How can two phones have the same battery size and one of them have double the life??

No issues here I just have a question that doesn't seem to be answered anywhere. How can the ASUS zenfone 4 max have the same batter size 5000 mAh as the ASUS Zenfone 3s. Yet have basically double the battery life?? Is there something i'm missing here?? Does it have something to do with the power saving features?? I want to get a phone with exceptional battery life because I'm tired of charging mine so often because of my heave usage on a daily basis. ASUS seems like the way to go. However I'd prefer to get the 3s because it's smaller. Normally I go for the sweet spot of a 5 inch screen. Even 5.2" is fairly large for me but i'm willing to put up with it. 5.5" like the 4 max is just too much but for the double the battery life man maybe I'll just suck it up. Unless there is a way to bridge that gap.


Here is where I'm getting my info from:
