Slow iPhone? Apple’s iOS updates Aren’t to Blame

Apple’s updates to its iOS operating system do not cause its phones to slow down over time, according to new research that debunks claims the company intentionally slows down iPhones with software updates. According to data from more than 100,000 devices running iOS, Apple’s system updates do not cause phones to slow down. The research from Futuremark shows Apple has in fact kept most of its iPhone processors running at similar speeds to when they were first released.

While the release of new iPhone updates, such as iOS 11, often cause users to speculate their devices have slowed down, the researchers found that devices running iOS 9, 10 and 11 operated at consistent speeds. Across the iPhone series, from the 5s to 7 Plus, Apple has maintained a consistent level of speed even after new iOS updates, Futuremark’s test that measured the performance of internal processors showed.

“Rather than intentionally degrading the performance of older models, Apple actually does a good job of supporting its older devices,” said Futuremark.

The researchers added that a number of factors could affect the perception of speed. Updates can add features that use more processing power. New apps developed for the latest iPhones may not perform as quickly on an older device. This means, while the processing speed remains the same, the actual power needed to complete tasks could increase.

There have, however, been claims that the most recent iOS 11 update has had a negative effect on battery life for some iPhones.  Analysis from mobile security company Wandera found the average battery decay for an iPhone running iOS 10 under constant use is 240 minutes. For devices that have upgraded to iOS 11, the decay time is just 96 minutes. However, recent patches to iOS 11 appear to have limited the battery drain.

Wandera analysed the battery decay of 50,000 iPhones and iPads on its network that were used moderately to heavily. It compared the average battery drain over three days and estimated the average.
