After four tests, the official version of iOS 15.1 is fully pushed, bringing three good news

I still remember that when iOS14 was first released, many problems were also exposed. It was not until the official version of iOS14.1 that most of the bugs were fixed - such as disordered home screen icons and incompatibility of third-party apps. The same is true for iOS15. The initial version has a lot of low-level errors.

The bugs that have been exposed so far include but are not limited to: inability to post videos on Moments, frequent need to re-login to Alibaba apps, weather display errors, resource library freezes, Apple Watch cannot be unlocked by face unlock, error prompt that storage space is full, no switch for macro mode, prompt that SIM card is not installed, etc.

The point is that these problems are common and cover most models. I believe that Apple fans have more or less discovered them after upgrading to iOS 15. I can only say that in the future, when encountering a major iOS version update, ordinary users should not upgrade within a month and wait for the next official version.

As we all know, Apple released the first beta version of iOS15.1 in the early morning of September 22. After 34 days of testing, there were a total of 4 beta versions. The official version of iOS15.1 was finally pushed on October 26. The author also upgraded iPhone 11 to the official version of iOS15.1 as soon as possible, and shared 3 good news with you.

1. There is no “negative optimization” in performance

Before upgrading the system, I ran Geekbench 5 when the system was still iOS15.0.2, and the scores were 1331 for single-core and 3074 for multi-core. After upgrading to the official version of iOS15.1, I tested it again, and the scores were 1330 for single-core and 3107 for multi-core, which was a slight improvement. To be honest, after experiencing the shadow of iOS14.5, running the score after upgrading the iOS system has become my conditioned reflex.

From the running points, we can see that the performance strategy of the official version of iOS15.1 is more aggressive, and the fluency should be better. From my personal experience, after updating the official version of iOS15.1, the battery life and heating of iPhone 11 are basically normal, and there is basically no "negative optimization", so Apple fans can upgrade with confidence.

However, it should be noted that iOS15.1 has recalibrated the battery algorithm for iPhone 12 models. After updating iOS15.1, iPhone 12 owners may see short-term fluctuations in battery health - just be aware of this.

2. Most of the BUGs have been fixed, except for these 3

In the official version of iOS 15.1, most of the bugs have been completely fixed. I have been using iOS 15.1 for most of the day and have only found 3 bugs - but they are all minor problems that do not affect normal use.

First, the Chinese localization of the shortcut commands in iOS15.1 is not thorough enough, and when running automatically, the prompts become English; second, after updating the system, the iPhone 12 Pro model will still display "SIM card not installed"; third, there is a freeze when swiping up on the iPhone XS series to call out multitasking.

Apart from these three bugs, there are no other problems. To be honest, the "SIM card not installed" bug has been around since the iOS 15 beta, and Apple has never optimized it. Many Apple fans joked that Apple deliberately leaves some small problems with every iOS update, which is a disguised way of forcing you to continue updating the system.

3. Fulfilling the promise of the press conference, 2 new features have been implemented

At the iOS 15 launch event, Apple announced two new features: SharePlay and ProRes. These two new features have been implemented in the official version of iOS 15.1. Let’s briefly introduce them.

Support for SharePlay is the biggest change in iOS15.1. This feature allows "real-time screen sharing" in FaceTime (Apple's own video chat tool), which is equivalent to remote screen projection. With SharePlay, you can watch movies and listen to music together.

According to the disclosure of netizen zzcookie, it can even allow friends to directly cast the screen, watch you play games, and see every detail of the operation clearly - this thing is indeed a magic tool for long-distance relationships.

As for ProRes, it is a new video encoding format. Its advantage is that it retains more original information and can be directly played back and edited without converting the format, so the performance required is lower and the production efficiency is higher.

In other words, with support for ProRes, the iPhone 13 can have real professional video productivity - of course, this feature is too far away for ordinary consumers.

Final summary

In short, there is no "negative optimization" in this update of iOS15.1 official version. The bugs are basically fixed, and two new features are added. Whether it is stability or playability, they are further improved. If you are the owner of an iPhone 11 or above, it is highly recommended to update to iOS15.1 official version.

Finally, let’s do a small survey: Have you updated the official version of iOS 15.1? How is your current experience?
