Damn: Apple Admits They Slow Down Older iPhones Because Of Battery Issues!
Apple has confirmed that it does indeed slow down older iPhones, a feature introduced last year to protect against problems caused by batteries. The feature was implemented on the iPhone 6, 6S and SE last year during a software update, and on the iPhone 7 as of December with the release of iOS 11.2. The feature is planned to be rolled out to newer devices in the future.
