Recently, many users who upgraded to iOS 13.2 must be troubled by the fact that WeChat is frequently killed by the system when it runs in the background. After a few days, the WeChat team finally got good news. On November 2, WeChat said that Find the solution, the emergency joint test is being completed, and the repair will be completed as soon as possible.

After switching from other applications to WeChat, I often need to wait for the application to reload. Many users initially pointed to WeChat. The guess is that WeChat has a bug. Some developers have analyzed the system log and found that WeChat frequently calls wakeup in the background. The average wake-up of more than 300 times per second is considered to be abusing the wake-up mechanism and lead to being killed.

However, this time may be a WeChat. In fact, it’s not just WeChat that is killed by the background. Whether it’s YouTube, Instagram or Apple’s own Safari, it’s hard to escape in iOS 13.2, even if it’s The application switching interval will only be killed in a few seconds, and foreign users are equally complained.

A developer named Marco Arment wrote aloud on Twitter:

A big new bug in iOS 13.2:

Background downloads are often suspended and never run;

The app was killed in the background, and iOS doesn’t actually provide multitasking at all;

Continues the practice of iO13 breaking the long-standing basic functionality.

Arment indicates that this issue already exists in the iOS 13.2 beta. During the period, users continue to report problems to Apple. As a result, the bugs in the official version have not been resolved, but have been intensified, and Apple has not heard user feedback.

Arment’s Tucao received a lot of responses, and the famous Apple blogger John Gruber wrote:

The app was quickly killed after it entered the background. I was killed, opened YouTube in Safari, switched to another app, and then back to Safari, the video was reloaded and played from scratch.

After picking up a phone call, half of the emails are gone, the mail can’t be collected in the background, the game progress is lost, and the music player with the long-running background mode is also escaping. The practice of iOS 13.2 crazy killing the background has caused a lot of It is a disastrous consequence that makes users miserable.

It’s worth noting that this is not the case with the old iPhone. It also exists in the new iPhone 11 series. Even the iPad Pro with up to 6G of memory can’t handle multitasking… It looks more like The memory processing mechanism has a bug. WeChat also suggested that users should not upgrade iOS 13.2 at the beginning.

It’s unclear whether this is an issue with iOS 13, or only related to the latest iOS 13.2. The Verge Guessing this problem with a new generation of iPhones may be due to the large memory footprint of the new camera system, especially the iPhone 11 Pro, which requires more camera processing and is equipped with an additional camera.

In short, it’s hard to tell where the problem is. If it’s a system bug, Apple should fix it in a subsequent update. This is not the most buggy iOS version in history, but it may be the most disappointing to users.
