Popular apps are getting bigger and taking up more space when you install them on your iPhone
How much each of the top ten most popular iOS apps have grown in file size since 2013
Sure, the amount of native storage on your iPhone has risen sharply over the years. According to a report from Sensor Tower, the minimum storage available on an iPhone has doubled from the 16GB on 2013's Apple iPhone 5s to the 32GB on last year's Apple iPhone 7. But the truth is that Apple is not keeping up with the huge increase in the file size increases on popular apps. This is why many users of the iPhone are often looking for apps to remove in order to create space for new downloads.
To help with this issue, iOS 11 will send out recommendations to users suggesting that rarely used apps be offloaded. This would remove a core app while keeping data and settings in case you want to quickly load the app again.
