    Did a search but no luck. It always wonders me and I just want to know if it's correct. :confused:

    Are the app update data size in additional of the original app? or it just replaces the original app data size?

    For example, FB app is 10MB (just an example) and we have an update today at the App Store and it's showing 15MB. Is it in additional 15MB or just 5MB (15 minus 10)?

    Can someone please clarify? Thanks.

    Facebook is 57.5 MB (per the Facebook app information in the App Store). The app update is just as it says. If it's 15 MB, it's 15MB.

    Installed I believe Facebook is around 100 MB. Updates are not necessarily something that's on top of that simply by adding the update size to the app size, but they certainly can change the app size in some way.

    I believe it's the overall size of the app. This is why I rarely update large (1GB+) apps. I regularly run my iOS devices with only 400-700MB of free space. Infinity Blade for example may have a minor update (let's say 20MB) but it requires the full 1GB plus some extra room to shift things around, so maybe 1.5GB, in order to update.

    The entire app is downloaded and installed.

    The App Store will attempt to download delta updates (I.e. Smaller size) if possible but it is up to the app developer to make sure it does that.

    You can read a bit more about it here:


    This is incorrect if you're on iOS 6 and above.
