What's the difference between ios 10.0.2 and i0S 10.3.3?

First of all, compare the boot speed: running iOS 112.1is faster than running IOS 10.3.3, but the difference is only within1second.

Turn on the SMS function, and you can see ios 1 1.2. 1. Come on.

When the camera is turned on and the iPhone5 has entered the interface, the iPhone5S still stays in the camera loading interface.

Coincidentally, this morning, Apple pushed the iOS 10.3.3 version of the system to many models including the iPhone6s. As mentioned above, I really hesitated when I received the update reminder. The specific reason is not only worried about the runtime jam, but also worried about the serious power consumption and the serious shortage of battery power.

Finally, I couldn't help but want to know the new iteration of iPhone6s. However, it should be noted that the upgrade process takes a long time, prompting everyone to keep enough power if they want to update.
