Tests at google labs found that the feature extended battery life by two hours with 37 tags open (1 active ,36 backstage).
However, in the case of active video tags, the endurance improvement is not particularly great. For example, the playing oil pipe only lasts for more than 30 minutes.
According to Google, these features can be used not only for desktop, but also for mobile devices. Previously, Microsoft and apple always liked to compare the battery life to highlight the advantages of their browser over chrome, which may be reversed in the future.
