Apple has faced a lot of criticism and even lawsuits over the alleged software update charges that slowed down performance of older iPhone models. While the Cupertino based tech giant has confessed the allegations and offered a remedy by replacing the iPhone battery even it gets passed the capacity teat at a reduced price.

The question arises whether Apple will succeed in regaining the trust of its customers? We are not quite sure but we consider the step was taken in good faith as the older batteries degrade over time; not getting along with the high demands of the iPhone’s processor. Apple just started slowing down processors via software updates in order to prevent unexpected shutdowns; though without consumers’ consent.

How to Check iPhone’s Performance

We have come across an app where iPhone users can check on their own whether their device is performing utmost or getting slow. The app we’re talking about is available on iOS app store named Lirium Device Info Lite. The app measures the speed of iPhone’s main chip and displays a lot of other information on the iPhone’s internal activity.

Once installed on your iPhone, go to the top left menu of the app’s home screen and tap ‘This Device’ > ‘CPU’. Check the ‘CPU Actual Clock’ and compare it with the ‘CPU Maximum Clock’. If both figures appear to be the same, your iPhone is performing at its best and isn’t throttled by Apple.


For your info, the original clock speeds for processor chips associated with iPhone 6 and iPhone 7 are listed below for easy comparison with the actual clock speed of your iPhone’s chip:

  • iPhone 6 and 6 Plus: 1.4GHz
  • iPhone 6S and 6S Plus: 1.84GHz
  • iPhone SE: 1.84GHz
  • iPhone 7 and 7 Plus: 2.34GHz

Just reminding you that if your older iPhone is running on the older version of iOS, it is likely that it hasn’t been throttled at all as the throttling feature was introduced in iOS 10.2.1 almost a year ago.

However, Apple insists on battery replacement for $29 even if your iPhone passes the chip performance test.
