Apple admits slowing down older iPhones. But it's not a part of a conspiracy, it's to fix an issue. Geekbench conducted a test and found the age of batteries affecting iPhone 6, 6s, and 7 to be slowing down. Apple had attempted to fix the problem by slowing down CPU usage, a result that came from iPhones unexpectedly shutting down when the battery approached 30 percent of battery life.

Apple explained to Business Insider : "Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components." Additionally, Apple advises when using iPhone, iPad, iPod, and Apple Watch to avoid extreme heat
