How to check if Apple is slowing down your iPhone

Apple recently admitted that it has been throttling the performance of certain iPhones with older batteries to prevent unexpected shutdowns.

For those curious, it turns out that it's not too difficult to see if your iPhone has been affected.

The reason behind the performance throttling actually makes sense: As older batteries degrade over time, they can't 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 dialed down the speeds of iPhone processors in units with overly degraded batteries.

Still, it's no secret that the company should have been more transparent about the practice. When owners of older iPhone experience slow performance, the usual course of action is to buy a new iPhone. But had they known that their iPhone's slowing performance was due to an aging battery, perhaps those users could have opted for a battery replacement, which is much cheaper than buying a new iPhone.

Here's how to see for yourself if your older iPhone's performance has been throttled:
