![]() ![]() ![]() To gain a more accurate understanding of the latter result, we compare the bandwidth consumption of version 1.5.9 and version 1.5.120 when loading Alexa’s top 1,000 websites. This is an artifact of Brave’s auto-play which behaves differently between the old and the new codebase. The majority of the bandwidth savings measured for version 1.5.120 are associated with the load of which reduces its bandwidth footprint from an average of 19MB (version 1.5.9) to 13.5MB (version 1.5.120). Note that these savings are additional to the savings that Brave already realizes with respect to the major browser vendors. The below results show a significant performance boost provided by our new codebase: 3% CPU savings, 5% battery savings, and a staggering 18% bandwidth savings. Each bar shows the average out of 5 runs along with error-bars reporting the standard deviation. The figures below directly compare the two Brave versions with respect to CPU, energy, and data consumption. We present results obtained from a Samsung Galaxy J3 (OS: Android 9.0, CPU: quad-core 1.4 GHz Cortex-A53, Memory: 2GB LPDDR3, Battery: 2,600mAh) on a fast WiFi network in North America. Further, we simulate simple user browsing behavior on each page by scrolling up and down multiple times. In this test, we instruct each browser version to load sequentially the top 10 news websites. In the following, we focus on the results obtained when comparing brave-core-android (version 1.5.120) with the last version available from the previous codebase (version 1.5.9). This is realized atop of Batterylab,, a distributed platform for battery measurements we have realized in collaboration with Imperial College of London and Northwestern University. That is, each new version of Brave is tested against its predecessor to guarantee no performance regression. īecause browser performance is paramount at Brave, we have developed the first solution for CI battery testing (and more) on mobile devices. In addition, these savings make Brave for Android outperform DuckDuckGo, Vivaldi, and Firefox Preview as well, which were recently ranked as top performing browsers by Greenspector. These savings are additional to the savings that Brave already realized when compared with major browser vendors (30%-50% bandwidth and battery reduction compared to Chrome, Firefox, and Opera). ![]() This new version is a seamless transition for Brave users as the user interface remains the same, but it does provide performance enhancements such as battery savings (5%), as well as CPU and data savings (3%), compared to the previous version (1.5.9). ![]() For example, this unified codebase will enable support for extensions in Android in the future. The new release is based on the same Chromium code repository as our Brave desktop release, and will allow for easier implementations of features and fixes across desktop and mobile thanks to a unified codebase. The new Brave app for Android (version 1.5.120) is now available for download on the Play Store and has been completely rebuilt over the past few months.

Results from the experimental evaluation in this blogpost were produced by Dr. Brave now has 13.5 million monthly active users and 4.3 million daily active users ![]()
