The iPhone 12 and iPhone 12 mini are Apple’s less expensive offerings, with the regular model sporting a 6.1-inch display, while the smallest of them all getting treated to a 5.4-inch panel. Smartphones with bigger displays inherently feature a bigger battery and by translation, will deliver better endurance compared to the more compact devices. While it’s true that the iPhone 12 is superior to the iPhone 12 mini when it comes to battery life, the difference isn’t pronounced if you take a look at these stats.

The iPhone 12 mini looks incredibly small compared to the 6.1-inch iPhone 12 but according to Apple, customers won’t see those size differences when it comes to real-world battery stats. For example, one area where the company normally compares its two devices is video playback time, and the non-streaming test shows the iPhone 12 only garnered two additional hours compared to the smaller model.
