It is recommended to update to ios 15.6

Before the upgrade, I tested the endurance test under the system environment of iOS 13.6, simulating a 7-hour full power standby power consumption test in one night. The power consumption of iOS 13.6 is 6%. In addition, after upgrading to iOS 15.6, the standby power consumption in the same scenario is 3-4%. In daily use, I found that the power loss speed of iOS 15.6 is slower than that of iOS 13.6. Some friends may not feel it strongly, In the 3-hour simulated daily moderate use scenario (1 hour of King Glory, 1 hour of Tencent Video, and 1 hour of Tiktok), iOS13.6 consumes 59% of power, and iOS15.6 consumes 51% of power in the same scenario, which is indeed more power saving than iOS13.6.

The above is the specific content about whether to upgrade the iPhone 8 to IOS 15.6. Although the improvement of the battery life is not significant for users who have not changed the battery for five years, it is still worth upgrading for users who care more about the smoothness and signal. After all, the smoothness is the final factor that determines how long you can use it.
