If you have wondered if your iPhone is running slower than it should, here is how to check if your iPhone is being slowed by Apple. First a little background. iPhone users with older devices (iPhone 6 and 6 Plus and iPhone 6s and 6s Plus) were noticing that their devices seemed to be running slower than normal. This happened when they updated to the most recent iOS software. After some investigation and questions by the public, Apple made it known that they had intentionally slowed some older devices. This was done in order to avoid software crashes. As iPhone batteries age (as is the case with any Lithium-ion Batter) they lose some of their charge capacity over time and are not able to handle the demand for power in the newer software.

In response to this issue, Apple has announced that they will reduce the cost for battery replacements for certain iPhones to $29 for a limited time – through the end of 2018 (iPhone models that qualify are: iPhone SE, iPhone 6 and 6 Plus, iPhone 6s and 6s Plus, iPhone 7 and 7 Plus, iPhone 8 and iPhone 8 Plus, iPhone X). To read more about this battery replacement program, see this support page from Apple: iPhone Battery Replacement Program.

Now that we have gotten the background of this issue, here are the 5 simple steps to check if your iPhone is being slowed by Apple:

1. Download either the Lirum Device Info Lite (Free) or Lirum Device Info ($2.99) app from the App Store
2. Open the App and tap on the menu in the top left corner (the 3 lines icon)
3. From that menu, tap on “This Device”
4. Then, Tap on “CPU”
5. Finally, scroll down and compare the numbers between “CPU Actual Clock” and “CPU Maximum Clock”. If these numbers are different, than your iPhone is being slowed by the software and may qualify for a battery replacement. If the numbers are the same, then your iPhone is not being slowed by the software.

Here is a visual walk through of how to see if your iPhone is running slower than it should:

First, open the app and tap on the menu in the upper left corner.

Next, tap on “This Device”

Then, tap on “CPU” to see details specific to the processor on your iPhone.

Finally, scroll down and compare the “CPU Actual Clock” and the “CPU Maximum Clock.” If these numbers are different, then your iPhone’s speed is being slowed down by the system software installed on it.

My iPhone has a newer battery and is not being slowed by Apple because the CPU numbers are the same.

That’s it. Now you know how to check if your iPhone is being slowed by Apple. Be sure to take advantage of the battery upgrade program while it is being offered for $29 if your device is running slower than you think it should.
