However, another cheeky feature Google talked up was something called smart - or “delta” – app updates, and it looks like they’ve finally hit Google Play.
What the heck are delta updates? Well, what usually happens is, see, when you update an Android app on Google Play, it downloads the whole thing all over again.
However, with Google Play’s delta updates, only the difference in APKs is downloaded, potentially saving many MBs of mobile data.
Google hasn’t officially said anything about the feature being rolled out, however the guys at Android Police have posted a couple of videos seemingly showing delta updates in action.
A series of Android apps are updated, and the progress bar only goes as far as, say, 40-50% before apparently completing. Great stuff.
The Policemen also note that the recent Instagram update, for example, weighs in at 13MB, but only around 3MB is downloaded with the new delta stuff. Excellent.
