When it came to light that Apple was throttling processor speed for older iPhone models, the fallout was ugly. Apple explained that the throttling was meant to prevent iPhone models 6 through 7 Plus from shutting down when their batteries couldn't keep up with the demands of their processors. Apple also lowered replacement battery prices to $29 to assist customers in getting their iPhones back up to speed. Now, with iOS 11.3, Apple is letting go of the automatic throttling plan and allowing iPhone users the ability to decide for themselves whether they'd like to slow processor speeds when their iPhone's batteries aren't able to keep up. Let's learn more about the throttle setting on your iPhone, actually called the applied performance management feature, and where to disable this setting if you choose.
