The release of iOS 15.4 was eagerly anticipated. The support for unlocking the face recognition function even when wearing a mask is the most notable of the new features added this time. Foreign technology experts will test the old iPhoneSE iPhone6S iPhone7 iPhone8 iPhoneXR iPhone11 iPhone12 iPhone13 and other 8 models for running speed results, and the results are not satisfactory, even the latest release of the iPhone13 in the upgrade speed has become slower.

iPhone SE (Second Edition)

Given that this series has been released for generations in the past 6 years, the iPhoneSE released in 2016 still supports iOS15.4 upgrade. And the original iPhoneSE after upgrading to iOS15.4 and iOS15.3.1 for speed testing, the results are for, whether running system software or system software, the results are for iOS15.4 to be slightly slower. Do you still want to upgrade your iPhone SE despite the fact that the old model isn’t as fast as it once was, and now the upgrade is even slower?

However, after testing the A9 processor single-core and multi-core scores, the results of the old iPhone SE upgrade iOS15.4 are slightly higher, both by 4 points. So, why is the running speed slowing down?

iPhone 6S (iPhone SE)

After upgrading to iOS 15.4, the iPhone 6S, a loyal Apple user, ran almost as fast as iOS 15.3.1, with the system software running almost at the same time, whether it was opening photo albums or maps. When opening small software like Oil Tube Subway Runner, it is still slightly faster than iOS15.3.1 when running first-party application software. Such performance is far superior to that of the previous iPhone SE, at least in terms of speed reduction.

When comparing the iPhone 6S processor score to the software running speed, the results are nearly identical. The processor score of the iPhone6S dropped slightly after upgrading to iOS15.4, the single-core score did not drop much, but the multi-core score dropped more than 20 points, which is not surprising?

The iPhone 7 is a smartphone that was released in

The iPhone7’s performance is also crotch after upgrading to iOS15.4; however, in terms of system software testing, it’s almost tied with iOS15.3.1; this result is also similar to the iPhone6S. However, when it comes to running first-party software, it’s almost completely backwards, especially when it comes to opening a small game, the gap is visible to the naked eye, and the running speed is significantly reduced.

The processor score explains why this is the case. The single-core score dropped by 71 points after the iPhone 7 upgrade, while the multi-core score dropped by 64 points. I didn’t expect the performance to drop so drastically after the upgrade; this is an unexpected result, and it’s no surprise that the running speed will suffer as a result.

The performance of the iPhone 8 is far superior to that of previous models, and the system software is as fast as ever. However, iOS15.3.1 is almost always in the backward state when it comes to first-party application software, open foreign social software, whether it’s pictures or text loading. Fortunately, only two software applications have slowed; other first-party apps are still running at top speeds, tied with iOS15.3.1.

The iPhone 8 processor score test results after the upgrade are unsatisfactory; single-core score increased by one point, but multi-core score decreased by more than 200 points, implying that the iPhone 8 will be slower to respond when multi-tasking is opened.

iPhone XR (iPhone XR)

Also disappointing is the iPhone XR, which, after upgrading to iOS 15.4, becomes slow and sluggish when opening third-party apps. When opening the oil tube in the test, you can see that iOS15.3.1 is very fast, whereas iOS15.4 is about 3 seconds slower. I did not expect the upgrade to widen the running speed gap so much.
bestbuy618 bestbuy618

In the processor score test, after upgrading to iOS15.4 on the iPhone XR, both single-core and multi-core scores dropped, suggesting that iOS15.4 caused the model’s overall performance to drop. Can you accept such a result?

iPhone 11 (iPhone X)

The performance of the iPhone 11 is even worse. This is still a two-year-old model, and I was surprised to find that after upgrading to iOS15.4, even some of the system software’s running speed has slowed. The weather and maps software on iOS 15.4 were almost a second slower in a test compared to iOS 15.3.1. The difference is obvious if you use first-party applications.

The test iPhone11 processor score is also speechless; while single-core scores did not suffer significantly from the upgrade to the A13 processor, multi-core scores suffered significantly. The fact that the upgrade to iOS15.4 has resulted in a performance drop is once again highlighted. In addition, wearing a mask to unlock 3D face recognition on the iPhone 11 is not supported.

12th iPhone

When the iPhone 12 was updated to iOS 15.4, it added support for wearing a mask to unlock 3D face recognition, but the running speed dropped slightly. Only this time it’s okay, compared to previous models of the overall decline, iPhone12 is running iOS15.4 only when opening anonymous social software, only half a beat slower than iOS15.3.1, the difference is not very large, only when you slow down the camera can be found.

Even though the operating speed does not slow down, the iPhone 12 test A14 processor scores, single-core and multi-core scores are down, which can’t change the fact that performance is declining.

13th iPhone

When compared to the previous seven iPhone models, the iPhone 13, the most recent model, runs at nearly the same speed as iOS 15.3.1 after upgrading to iOS 15.4. The loading of pictures and text is very smooth in both the system software and the first-party application software. However, there is no overall increase in running speed.
bestbuy618 bestbuy618

Single-core scores on the iPhone 13 are 11 points higher, while multi-core scores are only 1 point higher. Even if the speed test with iOS 15.3.1 is tied, it can’t hide the flaws that iOS 15.4 has exposed.

Users of the iPhone 12 and 13 series may want to upgrade if they want to use a mask to unlock the 3D face recognition feature; after all, only these two series of iPhones support the feature.
