I created a new thread on this since.

I've been doing power consumption tests on my iPhone 11 and my Pixel 7
Pro to see the difference in power consumption using different browsers
displaying the same content.

The spreadsheet is here:
<https://docs.google.com/spreadsheets/d/1JYAlRUquCeEOUj8iKVZXvLi5Hf1p8tDKtOHVj_b8VKk/>

Each phone was charged to 100% then the same content was run on each
browser. I measured the energy consumption using a USB-C
voltage/current/watt/watt-hour meter. Prior to running the content on
the browser I did a baseline test to see what the power consumption was
with no apps open and the screen at 100% brightness with a full screen
of icons. Then I opened a browser and ran the content.

In a nutshell:

For iOS, Safari used significantly less energy than Chrome or Firefox,
and moderately less energy than Opera.

For Android, Chrome used significantly less energy than Firefox or Opera.

This was not to compare Android versus iPhone power consumption since
clearly these are two devices that are very different in terms of
processor and display.

I may also do the test a different way, running each browser for x
number of minutes to see how much battery is used up. This will be a
good sanity check on the power-meter test results.

your claimed methodology *can't* measure energy consumption for
specific apps.
