Older iPhone will take a hit in performance: Apple confirms
Techies over Reddit noticed Apple was slowing down older iPhone models with low battery capacities. Many users over time have been reporting the loss in performance when they updated older iPhones. It appears that now we have proof that Apple was diminishing processor speeds with declining battery capacities of iPhones over time.
GeekBench found out over time Apple is throttling performance
John Poole, a developer at GeekBench mapped performance over time for iPhone 6S and iPhone 7 and found out that Apple rolled out iOS 10.2.1 and iOS 11.2.0 to introduce throttling to older devices. Apple seems to be solving random shutdown issues on their devices with these updates.
Another Reddit user reported that replacing their batteries has returned performance and clock speeds back to normal.
So it's true Apple intentionally slow down old iPhones. Proof: My iPhone 6 was bought 3years ago and recently got really slow. APP 'CPU DasherX' shows iPhone CPU is under clocked running at 600MHz. After a iPhone battery replacement. CPU speed resumed to factory setting 1400MHz. pic.twitter.com/pML3y0Jkp2

This information is alarming for all Apple users who prefer to buy a new device rather than replacing their batteries when their iPhone start to randomly shut down.
When asked to comment on the matter by The Verge Apple said,
Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. 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.
Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.

What Apple is saying that there are secretly slowing down older devices with depleting batteries to rectify the issue of unexpected shutdowns. As the older batteries aren’t capable of handling peak performance with efficiency. Running iPhones with older device runs the risk of damaging its internal components.
