Google has officially rolled out Chrome 57 to iOS, Android, Mac, Windows, and Linux operating systems. The update is claimed to bring in a couple of upgrades and also enhance the overall browsing experience.

Google Chrome 57 update officially introduces background tab throttling. Software engineer and power saver Alexander Timin shared to Fone Arena, "We've found that this throttling mechanism leads to 25% fewer busy background tabs. In the long-term, the idea is for background tabs to be fully suspended and instead rely on new APIs for service workers to do work in the background."

With that being said, the overall impact of throttling results 25% fewer busy background tabs, resulting in an improvement in power efficiency and ideally, longer battery life for laptops or other mobile devices.

Gadgets 360 reports that the throttling feature will 'limit average CPU load to 1% of a core if an application uses too much CPU in the background'. It also detects background tabs that are playing music or maintaining a real-time connection, and leave them running as per usual.

Google Chrome 57 update also brings some welcome convenience to users on iOS, with Safari-esque 'reading list' functionality coming to Chrome. Under the "Share" menu, the rumored "Read Later" feature where the saved pages can be accessed without an Internet connection as they will be saved in the device.

This feature also split saved items into "Unread" and "Pages You've Read" sections for easy reference. To use it, click the "Share" icon on any page you want to save and then click "Read Later" to add it to your Reading List.

For devices with less RAM, this will boost performance in general. With tons of tabs open, it stands to reason that if those tabs get performance throttled, more system resources can be given to the task at hand. 

Google Chrome 57 is also rolled out in Android while the iOS version numbered as 57.0.2987.100.
