Opera Power Saving Mode will save your laptop’s battery by up to 50%

Opera has made battery saving possible, thanks to optimisations like reducing activity from background tabs, adapting page-redrawing frequency and tuning video-playback parameters.
Opera has introduced a power saving mode for its browser, which it claims can extend the laptop battery life by up to 50 per cent. Opera says having many tabs open often results in rapid battery drain that reduces a laptop’s performance. Opera 39 has been rolled out starting today in the developer stream.
