Android App update will get shrink upto 65% less

Google addressed the issue earlier this year by switching to a new compression algorithm, which the company says reduced the size of an app update by 47 percent on average.

 Now, the company has made even bigger progress by using an app updating technique called File-by-File patching which makes app updates 65 percent smaller on average compared with the full app.

An update to Google Maps was previously 17.5MB; now, with File-by-File patching applied, only 9.6MB

For a detailed overview of how File-by-File patching works, see Google’s blog post, or go to the project’s Github page.
