No changes are made (even if some options reduce the consumption of energy or resources: data saving mode, dark theme, etc. Once the application is downloaded and installed, we run our measurements on the basic and original settings of the application. We can also look at the memory impact of consulting Wikipedia (the basic consumption of the browser is subtracted here). Probably a bug but it is annoying because elements still occupy the memory and processing operations can also exist: processing operations are confirmed on Firefox and Mint with the rate of CPU consumed by the browser process which remains high. Firefox remains however with 1, GB as well as Chrome and Mint with around 100MB. When the browser is closed, almost all browsers are no longer in memory. We can note that Firefox Focus, Mint, Duck Duck go, Opera Mini and Qwant overall consume little memory. If the browser offloads the memory for the non-active tabs, then the consumption will be lower. The management of tabs will also play a role. This is due to the consumption of navigation engines to analyze and store items. Then, with navigation, the memory consumed increases significantly. On the other hand, we see that Edge and Ecosia have a strong increase in memory. If we leave the browser inactive, the memory consumption of most browsers remains fairly stable. This total energy consumption can be evaluated and analyzed in 2 ways: the energy consumption of pure navigation and the energy consumption related to the functionality of the browser.Īt the launch of browsers, we have a median memory usage of 413MB. Note that the most popular browsers: Edge, Firefox, Chrome, and Samsung, are quite poorly classified. On the side of the most energy-hungry browsers, we find Mint and Opera Mini. Ecosia loses its leading position on this indicator and finds itself in the middle of the ranking.
The version evaluated in 2020 was one of the first versions and it seems that Firefox teams have been working on optimizing the power consumption of their browser since. The average power consumption is 49mAh (as a reminder, the 2020 ranking average was 47mAh or -4.2%).įirefox Focus is the best solution in terms of energy consumption in our comparison.
