iPhone 12 mini real-world battery life?

Hi everyone! I'm thinking of upgrading from my iPhone 7 to the iPhone 12 mini. Reviewers claim that the 12 mini's battery is worse than expected when using 5G, but I can't find any data for battery life on wifi. If anyone here is using a 12 mini on wifi, how many hours of battery life do you get?

I'm a heavy user of social media, but only on wifi, so I want something small with a sufficient battery life for all-day scrolling. Thanks!
