After testing power saving mode  for Windows and Mac, in developer and beta streams, today, Opera Software has made the battery saver feature part of stable channel with the release of Opera 38. The browser company says the feature not only saves battery life and extends your browsing time, but also reduces the laptop temperature by 3 degrees.

If you’re using a laptop, disconnect the power adapter for the Power saver icon to pop up in the Opera address bar, then turn on the mode. Under the hood, Opera saves battery by  doing below tasks.

  • Reduces background tabs activity
  • Wakes CPU less often due to optimal scheduling of JavaScript timers
  • Automatically pauses unused plug-ins
  • Reduces frame rate to 30 frames per second
  • Tuns on video-playback parameters and forces usage of hardware accelerated video codecs
  • Pauses animations of browser themes
