Apple recently admitted about throttling the performance of older iPhones. Here’s how to check if Apple is slowing down your iPhone.

Old iPhone users have always believed that Apple deliberately slows down their devices to force them to upgrade to a newer model. In the past, we have also come across battery issues with iPhone 6s where users reported of unexpected shutdowns, and phones not turning on. Recently, Apple admitted that it had been secretly throttling the speeds of iPhones with older batteries to avoid unexpected shutdowns.

Apple offered a public apology for the same and also announced a discounted battery replacement program. Under this program, the replacement battery cost has been cut down from Rs 6,500 to Rs 2,000, plus taxes. Apple has also promised that it will issue an iOS software update with new features that will also offer information about the iPhone’s battery health.

As older batteries degrade over time, they can’t cope up with the processor’s high demands, thus causing unexpected shutdowns. However, Apple in its letter said, “it will never do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades.” So, how to find if Apple your iPhone has been throttled?

Users can head over to App Store and download the ‘Lirum Device Info’ app. It is a paid version priced at $2.99 (approximately Rs 190), but there is also a lite version of the app that is free, and can serve the purpose well.

After you download the app, open the app and it will ask you for permission to send notifications. You can either allow or deny, the permissions. Next, on the home screen, tap on the hamburger menu on the left, followed by ‘this device’ and then tap on CPU. Here, you will see chipset details such as the model, cores and the manufacturing process.

Comparing clock readings

You will see two more options – CPU Actual Clock (the current clock speed of your device) and CPU Maximum Clock (the maximum clock speed). As Business Insider points out – if both numbers are the same, it means your iPhone is running at its peak performance. However, if both numbers are different, it means the performance of your iPhone is throttled.

Apple iPhone 5s

We tried the app on an iPhone 5s running iOS 11.1.2 and we noticed that the peak speed is 1.4GHz, but the actual clock speed of the device CPU is slightly lowered to 1.3GHz. Well, a difference of 100MHz in clock speed won’t cause a drastic impact, but it has been throttled for sure.

Apple iPhone 6, iPhone 6s, iPhone SE

Apple introduced performance throttling feature for the iPhone 6, 6s, and SE in iOS 10.2.1. If you have one of these phones, and running iOS version 10.2 or below, the performance won’t be throttled. Similarly, for iPhone SE, the throttling was introduced in iOS 11.2.

The peak speed for iPhone 6 and 6 Plus is 1.4GHz, for iPhone 6s, 6s Plus and SE, it is 1.84GHz, whereas for iPhone 7 and 7 Plus, it is 2.34GHz. So, if have any of these iPhones and the app shows actual speed less than the one mentioned here, performance may have been throttled.
