Aren't the savings more in the type of application? For example, driving users to addictive content makes them use their phone more. Also, Bitcoin comes to mind.
To me, the amount of electricity used is a similar issue to RAM. Just because we have computers with more RAM does NOT mean programs NEED to use that RAM. So many applications right now that don’t need as much memory as they are using but, whether it be lazy or poorly planned code or any other excuse, they guzzle it up like they are the only application running on your device.
I’m all for figuring out what’s the most efficient option while also ensuring it’s an effective one as well. If you kept a knife in its sheath to keep it nice, but never take it out to use it, then it’s not servicing its purpose as a tool (ignoring ornamental ones). However, no matter how cool it might seem, you really don’t need a samurai sword to pear apples.
