iOS16.2 version number has been out for many days like the RC version, and the fluctuation fluctuates significantly after the official version. The smoothness has returned to normal today! The battery life is still significantly lower than the previous versions of iOS16. Let’s take a look. The
test uses Geekbench battery life stress test, and the test items do not include factors such as baseband and Wi-Fi. It is closer to the use scenarios of medium and high load under stand-alone games and Wi-Fi. Everyone has different usage habits, so it is for reference only!

iPhone13 A15 and A14 iPhone12 are still quite obvious, and it has dropped from the peak level of the battery life close to iOS15 to the average line of the iOS15.
This update of iPhone11 and iPhoneXr has slightly improved, but the improvement is not large.
iPhone 8, as the oldest model supported by iOS16, has slightly reduced battery life, but there is not much room for decline. The older the model, the lower the priority of optimization. I suspect A11 has not done any optimization at all!
If game users accidentally upgrade iOS16, they can now downgrade iOS15.6RC version through online flash and then OTA to iOS15.7.2 official version!
