@jaffathecake Okay, I know it's a weekend and we should all have our weekend brains on... BUT... If you were to do a blog on @FIAFormulaE teams website's, is there a way to measure the energy usage of a page?

This is a really good idea. I'm not sure how to measure it though.
@slightlylate do we have a way to capture something like number of CPU cycles across all threads? That wouldn't include GPU, but it feels close.1 reply 0 retweets 1 like -
It’s been difficult for me to find anything. I’ve been aware that the XCode gives iOS devs energy usage debugging tools, as it ties into the “do no harm” mantra of App Store submission. But there’s very little on web experiences.

It’s worth thinking about as PWA adoption is on the rise, particuarly in developing markets. We’ve always associated a fast experience with a good experience, but but a dead battery is no experience.

We can get thread active times from tracing w/o deep system instrumentation. On desktop, Intel's CPU counters are a decent starting point, e.g. under VTune: https://software.intel.com/en-us/vtune

Chromium has tended to measure end-to-end power use with specialised hardware rigs, including the BattOr: http://cseweb.ucsd.edu/~schulman/battor.html …

These used to be in our continuous perf infra and might still be. If they are, you might be able to schedule test runs on them.
