Ipados 15.6. 1 and 15.7.

1, 15.6. 1 still saves electricity. Usually it is full in the morning, and it is not filled in the middle. In this way, I thought 15.6. 1 had a bad battery life, but I didn't expect it to be the peak.

2. The upgrade of 15.7 still needs to be cautious. The screen will be on for more than five hours at most, and the battery health is consistent. IPadOS is a new operating system developed by Apple, which mainly uses the big screen and stylus of tablet computer, and mainly focuses on split screen and multi-task interaction, and can share tasks with notebook computer.
