The iPhone 12 mini is here, and Apple is copping some flack for the device's underwhelming battery life. The 5.4-inch iPhone has a 2,227 mAh battery, so it should come as no surprise to see it barely lasting a full working day between charges.

battery seems fine; more worried about those uncomfortable sharp edges when you hold the phone and an old model 5G modem which drains the battery...
Sharp edges were the norm till iphone 5s (and first SE). Nobody said they were uncomfortable... especially on small phones
It's all about perspective. As an upgrade to my 7 the battery life is actually improved not worsened.
