2. Cancel the low battery tone
After the upgrade of IOS 12.2, the iphone canceled the voice reminder when the power is lower than 20%, and only kept the prompt box.
3. Support the latest AirPods2
The upgrade of IOS 12.2 provides support for the latest devices, such as AirPods2. If you don't upgrade, there may be problems such as pop-up animation not being displayed, mute probability of one ear, delayed typing sound and so on.
What problems may occur after the upgrade?
1, fluency problem
IOS 12.2 adopts Apple's latest Swift5.0 kernel programming language, which reduces the size of the APP, reduces the space occupied by the system and third-party apps by more than 20%, improves the switching speed of the app, and improves the smoothness of the system operation to some extent.
2. Endurance problem
Some netizens reported that after upgrading to the latest IOS 12.2, the battery life decreased and the battery was not durable. The decline in endurance may be caused by two reasons. First, the OTA upgrade method will lead to unstable system operation and increased power consumption, and the iTunes upgrade method will be much better. Second: the battery health is below 80%, so the battery life will be greatly reduced. It is recommended to replace the mobile phone battery.
In short, for iphone X, it is very necessary to upgrade IOS 12.2, which will not cause fluency and battery life problems. After the upgrade, support for Liu Haiping has been improved, including support for telecom VoLTE and the latest Apple peripherals.
