During I/O 2012, Google announced a new feature that would launch in the Play Store known as smart app updating. While it isn’t anything monumental, it is a nice feature implemented by Google that represents pragmatic thinking by the Android team in what the user and carriers want.
The update is reportedly live in the Play Store as it occurred with the recent 3.8.15 Google Play Store update. Basically, whenever an app receives an update, your smartphone will only download the portion of the app that actually changed. For example, if you have a 20MB app, but only 5MB of it actually changed, the new system will only push out the 5MB that changed. Why download another 15MB when you don’t have to? Over the long run, this will save users time and data that can be spent doing other things.
In case you aren’t running the latest version of the Play Store, you will be happy to learn that the update is retroactive, meaning other versions of the Play Store can also perform smart updates.
