IOS 15.7 performance
1. Endurance performance
The battery life performance of iOS 15.6 is not satisfactory. The power consumption of 5-6 hours of standby every night is about 5-6%. The previous factory system consumed about 2% of power every night. The power consumption of upgrading to iOS 15.7 is only 3%, which is almost the same as that of the factory system. After the 3-hour battery life test, the remaining power of iOS 15.6 is 41%. The remaining power of the same 3-hour battery life test upgraded to iOS 15.7 is 48%. The battery life is improved to a certain extent.
2. Signal performance
In iOS 15.6, when I went to some business districts with large traffic, the signal immediately only had 1-2 grids, and the network speed was significantly reduced. In the special scenarios such as upgrading to iOS 15.7 business districts with large traffic, the signal could be kept at 2-3 grids, and the network speed was much better than before.
3. Fluency performance
There are still some frames stuck in iOS 15.6, mainly due to multi task switching, Taobao and other apps sliding frames, and upgrading to iOS 15.7. The situation of frames stuck in iOS 15.6 is obviously improved. The sliding in Taobao and other apps is very smooth. In addition, the game loading speed is faster than iOS 15.5.
4. Heating
In the daily use of iOS 15.6, there will be a certain amount of heat. In the game, the heat is a little hot. Upgrading to iOS 15.7 for daily use does not cause much heat. Even playing games, the heat is lower than the previous system version. The game frame number can always be maintained at a high frame number.
You must have known which models of IOS 15.7 are not worth updating. For example, the models released by Apple three or five years ago suggest that you should not think about updating the system, otherwise they may become bricks. Although the old system has few functions, it is better than stable flow.
