This is the heart of the issue, which is difficult for people to understand.
Just because you have to swap the battery two or three times throughout the day on your Galaxy Nexus doesn't mean you'll have to do that with a modern phone. Compared to modern flagships, the Galaxy Nexus has awful battery life- it's a fact.
I also owned an S3 and never had to charge during the day unless I was doing some heavy usage. 90% of days I had no need to charge until I went to bed.
Both the Galaxy Nexus and the S3 have removable batteries, but I've never once swapped batteries. I prefer to just carry an external 10,000mAh charger, because I can use it for multiple devices, it's small, and overall just highly convenient.
Honestly, I have not swapped batteries on a daily basis since I owned a Nexus One.
