How to find out that the battery has been changed

If you want to check that the battery replacement (Premium Pack) has been done, it is very simple:

If you ordered a model lower than iPhone 8:

Go to Settings=> Battery=> Battery status: the battery will display a status of 100 or 99%.

If you ordered a model equal to or greater than iPhone X:

You have iOS 13 or lower: go to Settings=> Battery=> Battery status: the battery will display a status of 100 or 99%.

You have iOS 14 or higher and a model greater than or equal to iPhone X:

Unfortunately Apple has disabled the battery status screen if the battery has been changed outside the Apple Store (which is the case for your phone). You will therefore see a message showing "repair" and then a message explaining that the iPhone can not give the battery health because the battery was changed outside the Apple Store. No problem, you will be able to check the battery health in other ways.

There is a lot of software available to check the battery level. We recommend the 3utool software, available on Mac and PC at the following link https://www.3u.com/. iTunes must already be installed on your computer.
