Their tests showed an increase in battery life of 28% with 36 tabs open, with the active page being about:blank to demonstrate just how much juice those background tabs consume. This should also reduce the memory usage of background tabs, though you will still have to deal with the way it treats extensions. Obviously, if you don’t tend to have several dozen tabs open at the same time you will not see the same increase in battery life but if you do have several open it will still help a bit.

Scripts which are delayed by this process will be flagged in the dev console to help you if you do encounter issues.
