iOS15.1.1 official version: It turns out that the poor signal is not our fault

iOS 15.1.1 push: fix call disconnection

At present, Apple has officially pushed the official version of iOS15.1.1, but many Apple fans said that the latest system is the official version of iOS15.1, and they have not received any push, which makes them very confused.

Yes, iOS 15.1.1 is an untested version, nor is it a unified push version. It is an additional patch for the official version of iOS 15.1. iOS 15.1.1 is only pushed to iPhone 12 and iPhone 13 series. Old users of iPhone 11 and earlier will not receive push notifications, so you don’t have to worry about it.

The biggest difference between iOS15.1.1 and iOS15.1 is that the call drop problem has been fixed. For some reason, Apple seems to be a little rusty in adjusting Qualcomm's 5G baseband.

Many people may not know this situation because they haven't bought a new iPhone. Although I rarely make calls, I have also encountered call disconnections. Let me explain the specific manifestations of call disconnections in detail.

In addition, when making a call, there is a certain probability that a pop-up window will appear indicating that the call failed. This problem has caused me a lot of trouble. Once, when I was discussing something important with a friend, the call was suddenly disconnected. I could only explain again and again that the signal of the Apple phone was not good, and the scene was very embarrassing.

But I always thought it was because of the poor mobile phone signal and low coverage of community base stations, and I didn't think about the system. After all, it's rare to find a mobile phone that can't even make calls stably these days.

In short, if you have an iPhone 12 or iPhone 13, it is recommended to upgrade directly to iOS 15.1.1 to improve the stability of daily calls. Have you ever encountered a bug that causes call disconnections? Welcome to discuss it together.

Here is an appeal, don't blame Intel anymore, because iPhone 12 and iPhone 13 are both Qualcomm 5G basebands, the same as the Android camp. They are all Qualcomm 5G basebands, but Apple is an exception. This is obviously either a flaw in the algorithm or a problem with the body structure design.

Finally, let’s make a summary

Apart from this, there is no functional difference between iOS15.1.1 and iOS15.1, and the fluency has not been improved. The only change is the fix for the call disconnection problem. Judging from the current user reputation, no more bugs have been added, so you can upgrade with confidence.

Old users don’t need to worry, as iOS15.2 has been updated to beta3 and beta4 is expected to be released next week. Testing is nearing completion and it will be officially launched after known issues are fixed.

In short, if you have an iPhone 12 or iPhone 13, it is recommended to upgrade directly to iOS 15.1.1 to improve the stability of daily calls. Have you ever encountered a bug that causes disconnections?
