What are the advantages and disadvantages of upgrading to iOS15.3?

Happy Chinese New Year! I believe everyone has received the update notification for iOS 15.3. I have also collected a lot of user feedback and am ready to talk to you about whether upgrading to iOS 15.3 is good or not.

The first point is the battery life issue, which should be a problem for most Apple users.

This is a battery usage chart reported by users. It can be seen from the chart that the battery life has been improved to a certain extent. However, after all, Apple's old-age version is always the next one, so this cannot avoid the psychological reaction of users. It is still recommended to upgrade to the new model.

1. The storage settings and App Store software details no longer spin in circles. These two issues may be the best optimized issues in this version.
2. There is no big difference in fluency compared to other versions. There is no visible difference
3. For those who want to unlock the mask, you can update and transition. After all, 15.4 has the function of unlocking the mask.

Finally, I would like to summarize that iOS 15.3 is still very friendly to new models. The battery life of new models has been improved to a certain extent (not noticeable in old models), but some XR users and XS Max users feel that it is much smoother than before. It is recommended that new models be updated, and old models can stay with the previous version that they feel is smoother.
