Yes! Apple is slowing down performance of iPhones with aged batteries

A user expects degraded battery capacity with older batteries but it affects processor performance as well for iPhones. Yes, Apple is slowing down processor performance of iPhones with aged batteries and company itself confirms it. A discussion started by an iPhone 6s user through Reddit post that his iPhone became slow for few weeks and tried troubleshooting for the device but nothing works. Finally replacing older battery with newer one fixed the problem for the user.

Discussion draws attention of team of GeekBench and they decided to dwell deeper into the issue. GeekBench researched into the issue by measuring Kernel density GeekBench 4 score for iPhone 6s and iPhone 7 running different iOS. Results clearly states that Apple is deliberately slowing down performance of iPhones with older batteries. Here are the various graphs that are plotted after the research

GeekBench found out that, general problem is performance of phones gets worsen with increasing age of the battery installed. Second problem, it was not an issue till previous iOS versions, it has been introduced with iOS 10.2.1 through a software update. As in the start of the year, users were experiencing sudden shut down of their iPhones when battery reaches 40-percent of its capacity. Apple acknowledged the problem of iPhones shut down and released a software update to fix the same. Here, company applied the changes of processor performance slow down with aged batteries but it went unnoticed. Apple also applied same changes to iOS 11.2.0 for iPhone 7 as well.

As the discussion and research sparked controversy, Apple strongly accept that it had made changes to iOS and slow down of performance with older battery is itself initiated by the company. They explained the proper reason for that by saying – to prevent unexpected shutdown of iPhones which is caused due to trouble supplying the peak current that the processor demands. According to an e-mail sent by Apple to reuters

“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 condition. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.”

This might not be an specific issue to iPhones only because Li-ion batteries degrades in terms of capacity by the time and find it difficult to supply peak currents that is required by the processors to function smoothly. When this current is supplied in spikes, there are chances that it can affect the internal electronics of the smartphone resulting into damage of high price valued processor of the device.

Battery replacement can boost your iPhone performance

All iPhone 6s and iPhone 7 users can fix the problem by replacing old battery with newer one. However, original new battery costs around Rs.5,000 which is indeed a hefty price for just a phone battery.
