A battery case is just like a standard protective case which also provides your phone with the charge when it needs it besides protecting it. iPhone users most widely use battery cases because iPhone’s battery life is too short on a single charge (because of small battery sizes) and the charging time is too long.
Battery cases are much better alternatives for power banks because using and carrying power banks is a tedious job due to their sizes, weights and the wires attached to them for usage. Previously, Apple did not produce battery cases itself, although it did certify third-party battery cases as Made For iPhone (MFi) products.
However, upon seeing the success of battery cases for iPhones, Apple did not want to lag behind, so they started manufacturing their battery cases under the name of Apple’s smart battery cases. Now, what makes their battery cases quick is their compatibility with the iOS.
The iPhone can detect the charging in the battery case and views it on the home screen of the iPhone instead of the LED indicators on the battery case itself (like other battery cases that are not iOS compatible). Not only this, but you can also connect your iPhone to iTunes and sync it even when the smart case is intact.
