Apple has just announced brand new Smart Battery Cases for the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.

It would be wrong to say that the new Smart Battery Case for the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max offer exactly the same thing as last year. For starters, you get a slightly updated design to accommodate the larger rear camera module, but Apple went a mile further to add a dedicated camera button to the case which launches the Camera app when pressed. This works whether the phone is locked or unlocked. Essentially, this case doubles down as a camera grip for photos and videos both, which is pretty clever.
