The problem was flagged by a number of Apple users worldwide, even those using the fancy new iPhone 11 line-up.
But, fortunately, the Cupertino giant has paid heed to those complaints, releasing a patch for the glitch.
Here's how you can install it.
Frequent killing of background apps
According to several grievances shared by Apple customers,iOS 13 has been killing apps in the background much quicker than usual.
The issue, they said, triggers automatically and shutters an app within a few seconds of switching to another memory-intensive program, say like the Camera, Spotify, or iMessage.
It appears indirectly related to how the iPhone manages memory while multi-tasking.
The bug removes in-app progress
While the issue doesn't sound big, it's been creating a lot of problems by wiping users' progress in apps.
Essentially, if you are in the middle of a task on one app, say like writing an email or watching a video, and then switch to another, the first app loses all the progress you have made.
So, you'd have to start all over again!
Thankfully, Apple has released a patch
As complaints flooded online forums, Apple was quick to issue a patch for the bug with its latest incremental software release - iOS and iPadOS 13.2.2.
Once you install this update, the multi-tasking issue would be fixed and background apps won't close even if you stay on another app for more than a few seconds.
How to install this update?
To install the latest iOS update, plug your device to the charger, head over to the settings of your device and tap on General.
Next, tap on 'Software Update' and hit the 'Download and install'.
The update will then be downloaded, post which you will get the option to install it immediately, later at midnight, or get reminded about it later.
iOS 13.2.2 also fixes other bugs
Along with this, iOS 13.2.2 will also fix other minor bugs, including the issue that resulted in temporary loss of "mobile signal after a call" or the one "where mobile data may temporarily not be available."
