The Hidden Resource Drain
Google Chrome is essentially an operating system running within your operating system. Many Chrome extensions and Web Apps (like chat clients or notification services) require constant network access to function correctly. To facilitate this, Chrome has a feature that allows these specific background apps to continue running even after you have clicked the red “X” and completely closed all visible Chrome browser windows. While this ensures you still get chat notifications, it means Chrome’s background processes are silently consuming your computer’s RAM, CPU cycles, and battery life, which can severely impact the performance of demanding foreground applications like video games or rendering software.
Completely Terminating Chrome
To ensure all resources are freed up when you close the browser and stop Google Chrome from automatically running background apps and extensions, you must explicitly disable the background persistence setting.
Open Google Chrome. Click the three vertical dots in the top-right corner and select Settings. In the left-hand navigation sidebar, click on System (you may need to expand an “Advanced” section to see this on older versions). Look at the very top of the main panel for a toggle switch labelled Continue running background apps when Google Chrome is closed. By default, this is turned on. Click the toggle to switch it to the Off position (the switch will turn grey). From now on, when you close your last open Chrome window, the browser will forcefully terminate every single one of its background processes, completely freeing up your system’s memory.
