0 Since Apple released the iphone14 series mobile phones on September 8, many people should have been amazed by the system-level innovation of Apple , "Lingdong Island", this way of reducing the visual obstacles caused by the hole-punching screen through the combination of software and hardware is refreshing, and the attention of the ios16 system has also increased.
This is not, it's coming. In the early morning of September 13, Apple successively pushed ios15.7 and ios16.0 system updates to iPhone users. Many people don’t know how to upgrade, they are just afraid that the phone will become hot and the battery life will be poor after the upgrade. I believe that after reading the editor’s introduction below, you should know the correct upgrade posture.
Editor's own iphone 13 pro max has been upgraded from ios15.4.1 to ios16.0. It has been used for a day with heavy use, no obvious fever, and the battery life is long. It will not lose power all night when the battery is full. Compared with the old system, ios16 is much better, and the operation is very smooth. I have never encountered any bugs that cannot be opened on WeChat. It feels very good to use.

Correct upgrade of ios16 steps (13 steps)
Since ios15.7 is a regular security level upgrade, I will not introduce it here. Just directly upgrade OTA (click on the phone to "Settings" - "General" - "Software Update").
ios16 is a large version. If you upgrade across large versions, you must connect your phone to the computer and enter recovery mode to flash the machine. You must not upgrade through OTA. Although the OTA upgrade is already very mature, it is still far from flashing the recovery mode. For example, you already have a two-story house, and now you want a three-story house. Then you have only two choices. One is to add a layer on the original basis, and the other is to directly push down the original two layers and rebuild the three layers. Now you should understand why I highly recommend that you restore mode and refresh the system.
Next I will introduce to you how to use recovery mode to brush ios16.0 in . The whole process is more than 30 minutes. Please reserve time

patiently wait for icloud background to synchronize cloud text messages, address books, and photo information to the phone. If you find that it is not synchronized, open "Settings" - "icloud" to see if the corresponding synchronization switch is turned on.
summary
cross-large version system upgrade does not recommend OTA upgrade, OTA upgrade, and OTA upgrade is not recommended. If you are a user of iphone12 or above, it is recommended that you swipe ios16.0. If you are a different series of phones, it is recommended that you keep the existing system or upgrade to ios15.7. But if you happen to have one piece on hand or are about to own a piece of apple watch and plan to upgrade to watchos9, then you have no choice (for example, only ios16 has the fitness function), and directly upgrade ios16.0.
