iOS13.5 performance test: Do 5 old iPhones run faster after upgrading?

Apple has officially launched the official version of iOS13.5, which is the biggest upgrade of the iOS system in recent months. Google has also cooperated with Apple for the first time to track the information of the new coronavirus, and users can unlock their phones even when wearing masks. So has the running speed of iOS13.5 been improved? We will test it as soon as possible, comparing the speed of 5 old models including iPhoneSE, iPhone6S, iPhone7, iPhone8, and iPhoneXR before and after the upgrade, to see what the results are?

iPhone SE:

First, let's take a look at the performance of iPhone SE after upgrading to iOS 13.5. Compared with iOS 13.4.1, it is in an absolute leading position in the boot speed test. Although the iPhone SE is a model from 4 years ago, the boot speed still gives people a big surprise.

In the system software test, the speed of iOS 13.4.1 and 13.5 running on iPhone SE is almost the same. Even when running software such as maps and browsers with high performance requirements, there is almost no difference.

When running third-party applications, the iPhone SE did not show any particular advantage, and most software speed tests were almost tied. When running the small game Subway Surfers, iOS 13.4.1 was actually slightly faster than iOS 13.5, which was a surprising result.

iPhone 6S:

The performance of iPhone 6S is a bit disappointing. After upgrading to iOS 13.5, it not only has no advantage in boot speed, but it lags behind. This performance is actually worse than that of iPhone SE.

The iPhone 6S is not only that painful, after upgrading to iOS 13.5, whether running system software or third-party software, the speed is slower than iOS 13.4.1. After seeing such a bad performance, I dare not upgrade. You know, there are many iPhone 6S users, and after the final upgrade, the performance is like this, which is really speechless.

iPhone 7:

The performance of iPhone 7 is different from the previous two models. After turning on, the startup speed of iOS 13.5 is almost the same as that of iOS 13.4.1. Even if the camera is slowed down, the speed difference between the two systems cannot be observed.

In terms of running speed, iOS 13.5 and 13.4.1 are similar in speed, whether running third-party software or system software. From startup to completion of loading, no matter how large or small the performance requirements are, they are all completed synchronously. After reading this, I feel that whether you upgrade or not, you can't feel whether the speed is improved.

iPhone 8:

Let's take a look at the performance of iPhone 8 after upgrading to iOS 13.5. There is still a slight surprise in the boot-up time. It is not only ahead of iOS 13.4.1, but also the gap is about 2 seconds. This is also the model with the largest lead among several models.

In actual tests, there is no difference between iOS13.5 and iOS13.4.1 in system software speed tests, but you can feel that there are some changes in third-party software speed tests. When opening software such as Subway Surfers, Twitter, and Facebook, iOS13.5 is almost always in the lead. It performs much better than the previous models.

iPhoneXR:

Let's take a look at the performance of the last iPhoneXR. The result is still disappointing. There is no difference in the boot speed between iOS13.5 and iOS13.4.1, and it is impossible to feel the advantages of iOS13.5.

In terms of speed test, iOS13.5 did not take advantage of the system software speed. On the contrary, it was slightly faster than iOS13.4.1 when running Temple Run, YouTube and other software. Such speed advantage can only be felt through slow motion playback.

Summary: From the upgrade process of the above five old iPhones, only the iPhone 8 has improved in terms of running speed, while the speed of some models has not only not improved, but has even been slightly degraded. It seems that this time iOS13.5 has not made much improvement in performance and cannot improve the running speed of all models.
