How does the iPhone/iPod Touch save all of the progress that you make in a game app?

For instance, if you are playing Angry Birds and then you make a lot of progress and get lots of achievements, what happens if you delete the Angry Birds app from the iPhone/iPod Touch, will all the progress you made still be saved or will the progress you made also be deleted.

Whenever you plug your device into your computer with iTunes, it automatically backs up all the information from the device into a saved file on your computer with the device synchronization. Basically, it backs up all app data - game progress, app preferences etc. As long as you know that you've successfully backed-up your device into your computer, game progress will be saved and you can delete the app from your device without worry.

Sorry I don't have any idea about this.

  • Transfer game progress from android to iphone? I had an evo 4g lte and just got the iPhone 6. I know it's stupid but I've had the Kim k game on my evo and it's taken me about two months to get to a certain place in that game and I don't want to lose all of that progress(and sadly, some money). Is it possible to move the game's progress to my laptop and transfer it onto my new phone? With anything really?
  • Lost all of my progress on iPhone game? I have been playing this iphone game Two Dots for a very long time. I just recently got a new phone and when I reinstalled the game, it lost all of my progress. I tried connecting it to Facebook but it only saved my progress up to the 100th level. I was at level 500! I emailed the games support mail telling them my issue. Is there anything they can do about this? Can they somehow get me back to the level I was at?
