Benchmarks and lab tests aren't usually very accurate to actual usage, so it'll be interesting to see how the browser performs in real-life tasks. What's even more impressive is the fact that the Search Giant claims that these battery-related improvements are also available on older MacBook models. Google says that users may enable the Energy Saver mode in Chrome, to get an extra 30 minutes of battery life on the laptop. The model which was used for the test was a MacBook Pro M2 2022 (13-inch model with 8GB RAM), and was running on macOS Ventura 13.2.1. It managed to get 17 hours of browsing time, and 18 hours of YouTube video streaming on a single charge on a MacBook. The report states that Google ran some tests in Chrome 110 (version 1.100) to benchmark the results.

The Verge reports that these optimizations will also come to Chrome on Windows, Linux and Android in future updates. These optimizations were added to Chrome UI too.

Google also reduced the redraws in Chrome by detecting and ignoring unnecessary changes on websites including the style, layout, paint, raster and GPU steps. The data structures that were accessed frequently have been streamlined with optimized access patterns. The new version of Chrome has been optimized to handle JavaScript timers and internal timers, so they fire less often, in order to make the browser more CPU-efficient. The article also goes into detail about how Javascript timers wake up the CPU frequently, and drive the power usage of the program. This helps in reducing the short term memory usage and energy consumption, without affecting the long-term memory usage of the browser. The developers fine-tuned the garbage collection and memory compression for recently created iframes. HTML pages that are loaded/embedded in a page, and discovered some issues with them (see the spike in the screenshot). Google says that its team analyzed the performance of iframes, i.e.
