The upgraded iPhone XR is in daily use, with iOS 157.1 In comparison, there is no obvious difference between winning and losing.
With iOS 157.1 Compared to the slight decrease in battery life. Especially when the battery level is presented in digital form, the number of speed drops makes people's hearts beat (battery health 79%).
The upgraded device is better than iOS 157.At 1 o'clock, the fever has increased, and it seems that the temperature is not as well controlled as before.
In terms of network connectivity, iOS 167.2 Excellent performance, improving the previous network connection problems in areas such as the subway, making the Internet experience smoother.
In terms of background management, the new system has more proper control over applications, and will not easily kill background applications, although it is only a small improvement, but for the iPhone XR with 3GB of RAM, it is already a valuable progress.
For those of you who are yearning for the new features of iOS 16 and are worried about the performance degradation, my advice is: if you are willing to accept a little bit of battery life and heat issues, then the upgrade is a worthwhile adventure. After upgrading, don't forget to reboot the new system to wake up completely. If you encounter other problems, please leave a message in the comment area.
