If one thing browsers are known to consume, is lot of processor power resulting in battery consumption. Chrome is a classic example, in my experience, which whenever used on my Macbook Air, drains the battery pretty fast.
Lately Opera has made some real push to improve their browser experience, and the recent feature just nails it. In the experimental build of Opera, the company has introduced a battery saving mode which automatically triggers when the laptop is not connected to any power outlet. The company claims that this mode saves 50% savings in battery life compared to its earlier version, and Google’s Chrome.
SVP of Engineering, Krystian Kolondra, made this announcement stating :
It’s extremely frustrating to run out of battery on your computer, whether you are out traveling, watching videos, or you have just left your charger behind. Our new power saving mode will nudge you when the laptop starts to consume battery, and, when enabled, it can increase the battery life by as much as 50%.
How does this work? No brainer there, but Opera could be the first company to get this mode on browser unless it has been natively implemented in other operating system. Opera reduces background activity in taps which are out of focus, adaptive page-redrawing frequency, and turning video playback parameters. The company has implemented feature such that frequently opened websites are more responsive.
When using it for the first time, you will have to manually enabled the power saving mode which will trigger when your batter gets low, and then follow on.
