Dang. This is making me question if I made the right move going with the Pro. That’s really not that big of a difference in battery life.
Not wanting to make you feel worse - hopefully it doesn't apply to you - but for those people thinking the same who are in a country where the Pro models still have a physical SIM slot the difference in battery life might be even less. As far as I could see the article didn't explicitly state what version of the Pros it tested but given that sites like Tom's Guide tend to consider the USA one of their bigger markets I'm guessing that it's the US versions that they tested and I would expect the Pro and Pro Max with physical SIM slots to post worse results than we see here.
With these differences in battery specs now for the physical SIM variant vs the eSIM-only variant of the same models I really do think that anyone posting battery life test results on models that have those two variants really should explicitly state what variant is being tested - or ideally test both variants so that we can see more data on the differences.
