But if you are struggling to keep up with the growing number of apps in task switcher then there is a useful SBSettings toggle that has recently been released that helps you free up available memory in one go.
SBSettings also allows developers to create custom toggles that can be installed from Cydia so that users can access them quickly from SBSettings.
rono23 has created a custom toggle for SBSettings called Remove Background SBSettings, which allows you to remove all the apps in task switcher, thus releasing the memory used up by the apps.
I would suggest using the toggle when you feel that the performance of your iPhone has degraded as RemoveBG ends up also killing apps like iPod, VoIP apps that you would ideally like to run in the background.
You can follow these instructions to install Remove Background SBSettings toggle on your jailbroken iPhone:
Install SBSettings on your iPhone if you haven’t installed it already. You checkout this post for more details.
Launch Cydia from your jailbroken iPhone homescreen.
Tap on the Search tab and search for Remove Background.
Tap on Remove Background SBSettings to install it on your iPhone.
You should now see the RemoveBG toggle in the SBSettings menu when you swipe your finger on iPhone's status bar.
Tapping on the RemoveBG toggle will remove the apps from task switcher by killing the processes.
The toggle would have been even more useful if I could tell it, which apps to skip while removing the apps running in the background.
As always, let us know if you found this toggle useful in the comments below.
