The chart shows that on iOS 10.2, the performance benchmarks of most iPhone 6s devices are similar. However, the iPhone 6s score distribution of iOS 10.2. 1 presents multiple peaks, with the largest peak near the average value and several smaller peaks near the lower score.
In other words, after the release of 5438+1iOS 10.2. 1 in June last year, the performance of some iPhone 6s devices was affected.
Apple said in a statement that improvements have been made in iOS 10.2. 1 to reduce the number of users who encounter unexpected iPhone shutdown events. Uneven power supply of old batteries leads to emergency shutdown. Apple has adjusted the power management system on the iPhone 6s device, but the company has never disclosed specific improvement measures. However, the recent discussion on Reddit triggered netizens' speculation that Apple was deliberately slowing down the speed of the old iPhone, so as to maximize the power efficiency and stability when the battery capacity was reduced, and reduce voltage-related unexpected shutdown events. Geekbench chart and John himself believe this speculation. He said: "The difference between iOS 10.2 and 10.2. 1 is too great. When the battery condition dropped to a certain extent, Apple introduced measures to limit the performance of equipment. " The chart shows that the number of iPhone 6s devices with low scores on iOS 1 1.2 is more obvious, which may be because the battery capacity of many devices may have been severely exhausted about one year after the release of 6s, and Apple has taken measures to reduce performance.
Interestingly, iPhone 7 may also be affected. The chart shows that the distribution of Geekbench scores of devices on iOS 10.2, iOS 1 and iOS1.1.2 is almost the same. However, with the appearance of iOS 1 1.2, the rating of iPhone 7 began to decline like that of iPhone 6s of iOS10.
This means that Apple may deliberately reduce the performance of the old iPhone in order to maximize the power efficiency and stability when the battery capacity drops, but Apple has not publicly acknowledged this.
It is normal that lithium-ion batteries will naturally lose some charging and discharging ability after several years of use. IPhone 6s has been used for a long time since it was released in September 20 15, and some users may consider replacing the battery once.
