Apple’s launch of iOS 13 brings a dark mode to attract a lot of users to upgrade, but this version is also puzzling due to more bugs. In particular, Apple is now releasing a new official version to bring new features while fixing some known issues, but there can be no new problems in every version. The fact is that the current iOS system also has strange problems frequently. It seems that Apple keeps changing quickly and does not have good control over the quality of the version.
Killing the background apps means that when the application is switched to the background, the system directly ends its operation, and when the system ends its operation, it will actively release the memory resources occupied by the application. Normally, when a user sets an application to allow background refresh, switching to the background at least for a short period of time is not completely terminated by the system.
However, Apple’s latest release of iOS 13.2 version of the killing background apps is extremely serious, whether it is a third-party application or Apple’s own application are frequently killed. For example, a user sets the Microsoft Outlook settings to allow background refreshing, then uses compose emails, during which time they switch to other apps to view new messages. Just switching to the background for a few seconds, the Microsoft Outlook process is ended, and the emails and even drafts that the user just wrote are not saved.
At present, many developers have indicated on Twitter that the frequent killing background problem of iOS 13.2 version is likely to be related to the aggressive memory strategy implemented by Apple. As far as the device is concerned, the new camera problem of the iPhone 11 series requires a lot of memory resources to support, especially when the PRO takes photos and needs memory resource processing calculation.
I’ve noticed this since the first 13.2 betas, and Overcast users keep reporting it as well: background apps seem to be getting killed MUCH more aggressively than before.
(Especially on the iPhone 11 if you use the camera, presumably because it needs so much RAM for processing.) https://t.co/Qscmsj1OGY

Therefore, the aggressive memory management strategy implemented by Apple on these devices will frequently kill other processes and free up memory resources to improve the performance of the camera system. Of course, developers think that this radical memory management strategy may be flawed.
