Browser: Chrome should eat less RAM and conserve batteries


Chrome is a powerful browser, but it is also commonly seen as a resource hog, requiring more RAM than other browsers and draining the battery faster. In the Canary Nightly builds of the browser, Google is now testing a new memory saver, and the energy saver is also activated from 20 percent Save 10GB of RAM

The latest release of Chrome for the desktop comes with two different performance modes, with the new memory saver claiming up to 40 percent or 10 GB of RAM less than the previous standard mode. It is therefore not a question of a generally valid optimization of the browser; instead, Chrome simply keeps fewer tabs available in the main memory, which remain open in the background but have to be reloaded when returning to them. The performance of the active tabs should benefit from this, but Google also mentions improvements for complex applications running in parallel, such as video editing software or games.

The memory saver is to be offered for Chrome under Windows, macOS and ChromeOS, but cannot yet be found in the settings in the current stable build M108. However, as Ars Technica reports, there is an option in the Canary Nightly Build settings to keep all tabs active at all times. Google's support section explains where to find Memory Saver and Energy Saver in settings if it's a supported version.

Energy Saver from 20 percent remaining capacity

The Energy Saver can be activated automatically as soon as a notebook reaches the 20 percent remaining capacity mark. To save battery, Chrome limits the background activity of the browser and reduces the visual effects on websites with animations and videos.

Chrome M108 supports passkeys

In the current stable build M108, on the other hand, support for passkeys has managed to replace passwords and, in contrast to them, no longer allow themselves to be compromised or their owners to fall victim to phishing attacks. In addition, the IT world wants to use it to tackle shared, insecure passwords, where losing them means potentially breaking into multiple accounts.

Passkeys are generated on the login device and supported on Chrome M108 on Windows 11, macOS and Android platforms. Passkeys can be managed in the Chrome settings on Windows and macOS. On Android, the passkeys are encrypted and synced via Google Password Manager or other password managers that support passkeys. Saved passkeys can be used on Android via the autofill function for apps and websites. A mobile device with Android or iOS can also be used to log in on the desktop. In the Web-Dev area, Google explains how developers can use passkeys for their websites using the WebAuthn API.
