iOS 12.1 slows iPhone X and iPhone 8: how to solve the problem

iPhone 8/8 Plus and iPhone X: iOS 12.1 can slow down performance to prevent shutdowns. Here’s how to prevent iOS 12.1 from slowing down iPhone X and iPhone 8

Slower iPhone X and iPhone 8 with iOS 12.1

Here we go again, Apple has done it again.

With the release of iOS 12.1, which was released only a few days ago, Apple has reduced the performance (and therefore slowed down) iPhone X and iPhone 8. 

It’s not a simple assumption, it’s not just a hypothesis, but everything is confirmed by Apple itself through an official statement. The positive note is that those who do not want to slow down or reduce the performance of iPhone X and iPhone 8 with iOS 12.1, can easily solve the problem. And in this article we will see how.

But let’s proceed calmly.

Apple slows down old iPhones through iOS updates

This news is certainly not new.

If you remember, in fact, last year users realized that with the passage of time, their iPhone became increasingly slow.

After some time and after trying to cover it all up, Apple admitted and explained the issue.

Basically, starting from iOS 10.2.1, a control able to prevent sudden shutdown due to a damaged battery has been added to the operating system.

Basically, the iPhone learns to analyze the health of the battery and, if it sees that it is not in perfect health, reduces the working frequency of the processor (slowing down the performance of course) in order to preserve the battery. 

We thought that all this was “past history”, now clarified by Apple and falling into oblivion, but it is not so!

Apple slows iPhone X and iPhone 8 with iOS 12.1

This system that preserves the battery and the life of the hardware, in fact, has also been extended to the iPhone 8, iPhone 8 Plus and iPhone X with the 12.1 version of iOS.

After the release of this update, even the processor of the iPhone X and iPhone 8 can therefore be slowed independently by the smartphone to preserve the battery.

According to Apple: 

“Lithium ion batteries have a limited life. As the battery ages, its ability to provide a sudden increase in power when requested by the iPhone is also reduced. For example, if you start an advanced game or many applications simultaneously, the CPU and GPU send an impulse to the battery that will need to deliver more power. When the battery is new, the operation succeeds without any problem but when the battery has deteriorated, it may fail to provide the required energy, causing the device to shut down. To avoid this problem and protect all the components of the iPhone, Apple integrates a performance management system within iOS that, in some cases.

In a nutshell, therefore, even iPhone X and iPhone 8 become slower after updating to iOS 12.1.

How to avoid the slowdown of iPhone X and iPhone 8?

We come now to the strong and most interesting point of the guide.

If you do not want your iPhone to be slowed down by the iOS operating system, here’s what you need to do to disable this iOS software feature.

Basically, in a few simple steps you will go to prevent the iPhone X and iPhone 8 to reduce the frequency of the processor in case of battery is not super efficient (and since it is quite recent smartphones, I think that the battery status is not so problematic that it has to reduce the speed of the device).

Steps to follow to prevent iOS 12.1 from slowing down iPhone X and iPhone 8 are these:

Go to Settings> Battery> Battery Status

From there deactivates the mode that prevents shutdown (and slows down the performance).

NOTE: this button will only appear on devices that, according to iOS, have a damaged battery. It is therefore not said that your smartphone has been slowed down by iOS 12.1.


We have also concluded for this guide.
