Battery life for various OS & UI

[ryo]

Running PostmarketOS-Phosh (Edge), consistently seeing drain rates under 2%/Hr now.  Think the worst of the excess battery drain problems are soon to be behind us on all the well maintained distros.  Now the fight begins to make it more useful without killing the battery.  Lacking a bigLittle CPU design is going to make that challenging.

yeah, I have about 2% drain per hour on suspend. I can keep the phone in my pocket all day and it will have charge at night time.

drain while being used is an issue, if I use Firefox, for instance, to play the daily crossword on vox.com, I see 10% or more drain per hour, and I can easily drain the battery in a couple of hours checking Facebook

Conspiracy theory outlets are often filled with multiple ads per page, (forced) auto play videos, and other battery eating stuff.
And the overly bloated web designs which are difficult to navigate these days we're calling "modern" aren't doing much good to battery life either.
Neither are web browsers these days that got to the point of using more RAM than a video game just to be able to render these overly bloated websites.
Yes, it's perfectly possible to make modern looking websites that are lightweight, but for some reason nobody wants to make them anymore.

And Fakebook is designed to be a survelliance service that people are willingly using it, survelliance eats battery (in comparison, a standard degoogled Android phone can survive at least twice as long as Google Android on the same phone).

So I can very understand why battery drains on these sites quicker than on suspend (or maybe other websites that are relatively lightweight).
