The latest update of Google Chrome makes the browser more efficient and saves MacBook battery life when surfing the web or watching YouTube videos.
The browser was tested on a MacBook Pro 13 (M2, 2022) and allows seventeen hours of web surfing and eighteen hours of YouTube viewing. Google didn’t release battery life numbers before the update. The Verge tested the same MacBook and managed to drain the battery in 16 hours and 30 minutes by performing various everyday tasks.
Older MacBooks also benefit from longer battery life thanks to the new Chrome update. Google Chrome software developer François Doray has confirmed that the same optimizations will be made to Windows, Linux and Android devices in upcoming updates.
What exactly has changed?
The biggest change is that Google has refined the garbage collection and memory compression of recently created iFrames. This reduces energy consumption without affecting the use of long-term memory.
In addition, JavaScript timers have been optimized to start a device’s CPU less often and to completely remove stale timers. Chrome has also been optimized to ignore unnecessary style, layout, grid and GPU steps on websites.
Aside from the longer battery life, most of these changes aren’t immediately apparent to the user.
Addition to the energy saving mode
Earlier this month, Google released a new power saving mode for Chrome. This mode extends your laptop’s battery life by limiting unnecessary background activities such as visual effects on websites.
The search giant claims that enabling this power-saving mode can give you an extra 30 minutes of browsing time. This claim is based on tests with the MacBook Pro 13 (M2, 2022). That’s not a huge battery saver, but it could be just that extra time you need when trying to get something important done before your laptop dies.
