How about Apple 12.3 system?

Apple's 12.3 system is still quite good, and the fluency of the old model has been obviously improved after the update. The 7P I used before was a special card after upgrading to ios 1 1 Simply upgrade with version, and now you can clearly feel that this version of the system is very smooth.

As the third major version update of iOS 12, Apple has brought many optimizations and improved fluency. Many new mobile phone users iPhone? XS、iPhone？ XS？ Max、iPhone？ After updating iOS 12.3, XR's response speed has been improved, and the problem of black screen turning has also been solved, which is really gratifying.

Nevertheless, many people are afraid to update, because everyone thinks that the price of a smooth system is an increase in power consumption. In order to ensure that the battery life of mobile phones does not decline, users are more willing to stick to the old-fashioned system.

The power consumption of iOS 12.3 is indeed higher than that of iOS 12.2, but the difference is not big, only 1-2%, which has little impact on daily use. However, the upgraded system is indeed smoother and more stable, so whether it is a new device or an old device, I suggest you upgrade to the official version of iOS 12.3.
