Desktop Safari doesn&#x27;t have a &#x27;power saving mode&#x27; and it consumer less power than Chrome. Apparently MS Edge is the same (I don&#x27;t use Windows so I can&#x27;t know). These browsers don&#x27;t have user-visible tradeoffs, they&#x27;re just more power efficient.<p>Or is this just a case of Chrome being really really unoptimised and power hungry?
