Hacker News 上看到 Reddit 上的這則說明:「PSA: iPhone slow? Try replacing your battery!」。

他提到他的 iPhone 6S 很慢,本來以為是 iOS 11 導致的,結果發現他弟弟 (或是哥哥?) 的 iPhone 6 也是跑 iOS 11,但是快很多... 所以他就試著研究,最後決定換電池:

My iPhone 6S has been very slow these past few weeks, and even after updating multiple times, it was still slow. Couldn’t figure out why, but just thought that iOS 11 was still awful to me. Then I used my brother’s iPhone 6 Plus and his was... faster than mine? This is when I knew something was wrong. So, I did some research, and decided to replace my battery.

結果發現換電池後速度就上來了,上面這張是換電池之前,下面那張是換電池之後:

所以是在電力不足的情況下會降速?

iOS 上測試的軟體是 Geekbench 4,而官方也有給參考值 (Geekbench 的),在 iOS Benchmarks - Geekbench Browser 可以參考。如果在吃滿電、重開機,沒有背景的情況下還是很慢的話,有機會是類似的問題?
