We all know that as the years pass by, a phone’s battery capacity gets worse, but did you know that Apple deliberately causes a speed drop in their phones (iPhone 6, iPhone 6S, iPhone 7 with iOS 11.2) performance? Well neither did I, until this issue was brought to light a few weeks ago by a Reddit post. Turns out this is true as Apple had confirmed to TechCrunch that they’ve been slowing down phones with a poor battery capacity since last year to prevent unexpected shutdowns during peak current demands.
As the phone’s battery gets weaker the ability to deliver power more efficiently starts to decline, as a result during times when the battery needs to deliver a lot of power in a short period, the phone will start to shut down in order to protect its electrical component. This is actually a chemical issue rather than an “Apple” issue. And in order to combat this issue, the company has added a battery management system that tracks the effectiveness of the battery, so that when the battery is unable to meet the demands it can just cap the power available or spread power requests over several cycles, hence avoiding an automatic shutdown.
Therefore, iPhone users will experience a reduction in speed when the device is cold, has a low battery charge or has an older battery. This is not necessarily a bad thing, I mean yeah it sucks to have a slower phone but then come on it would be far worse if the phones just unexpectedly switched off from time to time and this certainly is not an attempt by Apple to make you buy a new phone. Some users’ find that replacing the phone’s battery could help out but swapping batteries in Apple phone isn’t exactly easy either.
