With the controversy surrounding the news that Apple was slowing down older phone models, there's now a way to 

see if your iPhone is working at full speed or if it's being throttled. All you'll need is an app.

Apple recently admitted that it has been throttling the performance of certain iPhones with older batteries to prevent unexpected shutdowns. The explanation they gave was that older batteries degrade over time, and therefore cannot cope with the high demands of the iPhone's processor. To prevent unexpected shutdowns that sometimes occur when processors don't get enough power, the company slowed down the speeds of iPhone processors in units with overly degraded batteries. Make sense? In other words, what a user experiencing slower processing with any of the older models is supposed to do is to replace the batteries and not be forced to buy a newer iPhone model. Well, that's by the way.

To check the status of your iPhone against optimum speed benchmarks of the company and determine if your iPhone needs a battery replacement, here's what to do;

NOTE: This is not to endorse 100% the report of battery apps as they are simply not reliable in reporting the health of your older iPhone's battery. The best is to get it checked by a service technician or any of Apple's stores.

1. Download 'Lirum Device Info Lite' app that tells you the speed of your iPhone's main chip.


Other Apps exist too which provides this information. For instance, CPU-Z works well for Android. I haven't tried it on an iPhone.

2.  In the Lirum Info Lite app, check the speed of your iPhone's main chip speed.

From the Lirum app's home screen, tap the options button on the top left (three horizontal lines) > tap "This Device" > tap "CPU" > and check the "CPU Actual Clock" against the "CPU Maximum Clock." If both numbers are the same, then your iPhone isn't being throttled.

Here are the original "clock speeds" benchmarks – the measure of speed for a processor chip for the iPhone 6 onwards:

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


If you have an older iPhone running an older version of iOS, it may not be throttled. For the iPhone 6, 6s, and SE, Apple's performance throttling feature was introduced in iOS 10.2.1. If you have one of those iPhones but an older version of iOS, your performance won't be throttled.

For the iPhone 7 generation, Apple's throttling feature was introduced in iOS 11.2. If you have an iPhone 7 generation model with an earlier version of iOS, then your performance won't be throttled.

Apple recommends that you get a battery replacement when your iPhone's battery can only retain 80% of its original capacity.
