ios15.7.5 system is good.

Apple version 15.7 is a system that improves defects. After updating to 15.7, it will greatly improve all aspects of the mobile phone. The first impression of iPhone 13 after upgrading to the official version of iOS 15.7 is that the smoothness has been improved. When comparing the smoothness of screen sliding with iPhone 13PM, the difference in look and feel is very small. The speed of opening APP is significantly improved compared to iOS 15.6.

When iPhone 13 was in iOS 15.6, it consumed 2% of the power on standby for 5 hours every night. After upgrading to the official version of iOS 15.7, it consumed 1% of the power on standby for 5 hours. It went out with 100% power at 8 a.m. As of 3 p.m., the remaining power of iOS 15.6 is 69%. The official version of iOS 15.7 has 75% remaining power from leaving home with a full charge at 8 a.m. to 3 p.m. The battery life improvement is indeed amazing.

Notes on Apple’s system update

Before performing a system update, we need to check whether the phone’s storage space is sufficient. System updates require a certain amount of storage space. If there is insufficient storage space, the update may fail. We can free up storage space by cleaning up useless files or uninstalling infrequently used applications.

Before updating the Apple mobile phone system, you need to pay attention to backing up important data, checking storage space, maintaining network stability, and paying attention to battery power. When doing system updates, we need to keep the network stable. If the network is unstable, it may cause the update to fail or an error to occur while downloading the update file.
