How to reduce data usage with Chrome for iOS
Google wants to help you cut back on the amount of data your iOS device uses while browsing the Web using Chrome.
Google recently updated Chrome for iOS with the typical bug fixes and a couple of new features. One of the new features is the ability to cut back on the amount of data used by your iOS device.
The feature reroutes non-SSL or Incognito Web browsing through Google's servers to compress the pages, resulting in less data being transmitted to and from your iDevice.
In order to use the new feature, and hopefully cut down on data consumption by Chrome, you'll need to launch the current version of the app and navigate to the Settings page.
Once in the settings section, find the Bandwidth option and select it, followed by selecting Reduce Data Usage. Move the switch to the on position to enable data compression.
Going forward you can find the statistics of how much data you have saved over the last month when browsing the Web using Chrome. Unfortunately, there's no way to see if the data saved was on Wi-Fi (which doesn't really matter at the end of the day) or while using a wireless data connection (tiered data plans; need I say more?).
This option was disabled by default on both of my devices, but if you'd rather not route any of your Web browsing traffic through Google's servers, you can follow these same steps to ensure it's turned off on your device.
