In the majority of users' cognition, replacing battery can improve the performance of mobile phone is ridiculous, but recently, this kind of thing is really happening on iPhone users. According to foreign netizens, the performance of iPhone 6 and iPhone 6S mobile phones has been weakened after upgrading iOS 11, but the performance has doubled again after changing batteries.
Therefore, foreign research institutions Primate Labs days ago specifically on this matter are discussed. They found several iPhone 6, iPhone 6S and iPhone 7, and asked them to run iOS 10.2, iOS 10.2.1 and iOS 11.2 system respectively, and then observed their performance.
As can be seen from the graph, the performance performance of the above devices running Geekbench 4 is quite different under different systems: the performance of the devices in iOS 10.2 system has not changed much, and the performance has begun to decrease after iOS 10.2.1. Among them, the performance of iPhone 7 on the iOS 11.2 showed a significant decline. Is the apple intentional?
It is reported that under the new system, apple deliberately reduces the performance of the old iPhone, so as to maximize energy efficiency and stability, rather than misunderstand the "plot to force the old user to change the new machine". This explains why the performance of iPhone 6S and iPhone 7 devices will improve after the replacement of the new batteries.
