Chrome Experimental Feature Will Throttle Javascript-Timer Wakeups on Backgrounded Tabs

Slashdot reader techtsp writes: Starting with October's release of Chrome 86, the web browser will offer a way to limit JavaScript timer wake ups in background web pages to one wake up per minute, restricting the execution of certain background tasksfor example, checking if the scroll position changed, reporting logs, and analyzing interactions with ads. Google plans to achieve this courtesy of a new experimental feature called "Throttle Javascript timers in background." Google recently experimented with a prototype that limits Javascript timer wake ups to one per minute. In this experiment, Google opened 36 random tabs in the background while the foreground tab was about:blank. At the end of the experiment, Google found that throttling Javascript timers extends the battery life by almost 2 hours (28 percent) for a user with up to 36 background tabs, and when the foreground tab is about:blank... Chrome will provide developers with a message in the DevTools console when a Javascript timer is delayed by more than 5 seconds.Read more of this story at Slashdot.
