Slow app when turning on battery saver mode on IOS

I was testing some features on iOS when I noticed that enabling the battery saver mode caused the animations to become very choppy.

I tried this on several Ionic projects, including a blank template with just an ionic-menu to test the animations, but the issue persisted.

Perhaps this is an intentional behavior. If it is, is there a way to work around this and ensure smoother animations despite the battery saver mode being on?
