Apple Allegedly Fixing Aging Battery Issues By Slowing Down Your iPhone 6 Or iPhone 6S

A Reddit post over the weekend has drawn a flurry of interest. A user named TeckFire owns an iPhone 6s, and he reported that a battery replacement significantly increased the device's performance running iOS 11. This led to speculation that Apple intentionally slows down older phones to retain a full day's charge if the battery has degraded over time.

The user did a GeekBench run, before he replaced battery, he got single-core 1466, multi-core 2512. After he changed this battery, running score jumps to single-core of 2526, multi-core 4456 results. The difference is very obvious. Therefore, he believes that Apple slows down phones when the battery gets too low, so you still have a full days charge.

TeckFire also mentioned the iPhone 6s shutdown problem that happened a year ago, Apple deliberately launched a free battery replacement program, and later through iOS 10.2.1 to address this issue. He suspects that Apple is lowering the maximum clock speeds of the device associated with the voltage through a system update, so the device no longer consumes too much power and causes a shutdown

The reason why iPhone 7 and later devices don't slow down is that the A10 Fusion and the A11 Bionic each have an independent "low-power" core (only one-fifth power of the high-performance core). Only high-load computing tasks will use high-performance core.

TeckFire recommends that you can use CpuDasherX this free app to check your iPhone 6s CPU speed. 1848Mhz is the factory value, if less than that value means the iOS reduced the CPU clock speed in exchange for battery life. So if you don't want to buy the iPhone X, how about considering changing batteries for your old devices.
