1️⃣Turn on 【Find My iPhone】
Steps: Settings → Personal Information → Search → Search My iPhone → Choose 3 options
✅Advantages: If your phone is lost, you can log in to the iCloud official website through your computer to lock your phone, and you can send messages to your phone (I once recovered through this function)
2️⃣Turn on [Optimize battery charging]
Steps: Settings→Battery battery health→Optimize battery charging
✅Advantages: It can slow down the charging speed of the mobile phone battery after being charged to 80%, thereby reducing heat generation and protecting battery life. Lithium batteries are not suitable for charging too fast when they are about to be fully charged, so it is necessary to turn on this function! ! ! Increase the life of the phone! ! !
