iPhone relieve: Apps in the Background close
The simplest cause would be that too many Apps are running in the Background.
- Press twice on the Home Button.
- To close a window, pull it up and out of the screen.
- Closing the Apps does not help, try a restart. This allows you to clean up the memory of your iPhone.
Storage space, if the Iphone is jerky
Also a restart doesn't help, next step is to check how full the memory of the device.
- Tap in the settings on the "General" and then on "Info".
- Check how much memory is still available. You can find this information under the term "Available".
- Less than 500 MB should be available, it may be the cause for the stuttering. You can delete Apps, music, pictures or other large files to create space.
- Tip: Under "settings - General - use" you can see which files and Apps up the most disk space.
