>>105895853I never said anything about battery life. Modern computer/devices have such OP CPUs that users won't notice AVIF/JPEG-XL raping all the CPU cores for 0.1 seconds to decode an image. The problem is older CPUs won't be able to do this and anything that takes longer than human reaction time isn't good.
I've tested this myself on some old thinkpads and as expected the fucking thing will freeze up for like a whole second while the AVIF/JPEG XL image is decoded and that's annoying as fuck.
