Last night Apple released the official version of iOS 15.3.1 push, the second more this week! Friends who have upgraded the iOS 15.4 beta version cannot downgrade through the mobile phone, and can only update this system by computer flashing. It is not recommended that some of the data caches that are downgraded will be different, which will cause instability and minor problems.
iOS 15.3.1
Compared to iOS15.3, the Geekbench5 score of iOS15.3.1 changes as follows:
- Single core: +3
- Multi-core: -4
- Metal： -2
Performance has hardly changed, and according to Apple, this update mainly solves the problem of braille displays stopping responding! Also released are iPadOS 15.3.1, watchOS 8.4.2, macOS Monterey 12.2.1!
The last time I posted a Bluetooth bug that caused the standby battery life to run out, I knew that I was going to release macOS 12.2.1, and finally it was here. This update resolves an issue where Bluetooth causes macBook battery consumption to be abnormal! This problem has finally been solved in such a long time since macOS 12.1 - macOS 12.2.1.
Battery life
I will update later, battery testing and usage experience, stay tuned.
