Chrome developers boast that this mechanic has resulted in 25% less busy background tabs, which translates to less power consumption. Of course, there will be exceptions to this rule, like tabs that are playing audio or those with real-time communications via WebSockets or WebRTC.
Google’s quest to improve Chrome reputation doesn’t end there. The developers have also shared their goals for the next quarters. For example, by the second quarter, all background timers should be suspended on mobile devices after 5 minutes, regardless of CPU usage. By 2018, all background tabs are to be suspended after a few minutes’ delay, unless a web page opts out of that system. Hopefully that won’t be abused so that we won’t end up in this situation again.
