iPad Navigation - App Shut Down to Save Power and Speed Up Processing Time

[BlowingOldBoots]

I have been using Navionics, Memory Maps and AngleNav as backup navigation Apps to my plotter. I am trying them out before deciding which one to keep. However, I discovered that they stay active when closed. Initially, this was noticed through the location services icon being switched on all the time, when one particular App was used, and the only way to stop it was to power down the iPad or quit location services for that App. I contacted the developer why they didn’t have a “Quit” option, when the other Apps did.

I was advised that Apple don’t allow Apps to shut down and when Quit is used they remain open. I expressed my opinion that power consumption is impacted, as the Apps continue to use location services e.g. GPS tracking. Likely they do a lot more analytics in the background as well. The developer kindly researched how to identify all open Apps and shut down.

To reduce power consumption and free up memory to allow faster App processing, do this:-

1. On the Home Screen, place your finger at the bottom of the screen and swipe up fast, pause, remove finger.
2. The app icons on the screen should shrink if done properly.
3. When the finger is removed all the open Apps appear as tiles.
4. With your finger, touch the App tile and flip it over the top edge of the screen and it completely shuts down.

This is for iPad 10 Operating System 17.5.1

I was not aware of this feature. You should be aware of it so that power saving and processor speed is optimized when navigating with your choice of navigation App. It is similar on the iPhone. Basically it is possible for many Apps to be live and consuming energy, processor memory space, GPS data and cellular band width. This could impact performance.

Below is a convenient YouTube video showing this feature.
