In addition to paying Apple a reported $1 billion for search traffic, Google has further boosted its efforts to drive iOS users to its search engine by improving its Chrome for iOS app.
The default Safari mobile browser for iOS doesn't take into account the cost of cellular data or the frustration of slow access networks. Android users trying to stay under the limits of their data plans have had an option that iOS users will now get with the Chrome for iOS update.
According to Google's blog post, 100 million Chrome for Android users turned on Data Saver mode, saving a total of 100 terabytes per day. At $10 per gigabyte, Chrome for Android users project to save $1 million per day and $365 million per year. Data Saver mode also speeds up browsing on slower Wi-Fi networks.
How it works
Google has distributed web proxy servers throughout the internet between Chrome users and website destinations. Google's web proxy compresses data sent from websites to the mobile user. It captures the user's requested browsing destination, submits the destination URL to the website, and then captures and compresses the webpage returned before relaying it to the user. That's a mouthful, more easily explained by the diagram below.
How to enable Data Saver mode in Chrome for iOS
Google claims a 50% reduction in the amount of data used in Chrome browsing sessions. iOS users who want faster browsing that consumes less of their limited mobile data plans should download the Chrome browser M48 from the Apple App store.
