If your Android smartphone running on Ice Cream Sandwich (Android 4.0 or above), here is how to enable “inverted screen rendering” to save battery life. It turns webpages black and white.
Remember, it only works with the stock Android browser. Run your Stock browser and tap your phone’s “Settings” menu. Under “Accessibility”, enable the option “Inverted Rendering”. All your webpages will now have black background with white text (black and white), which makes your screen use less power. Also, it helps you save your eye and gives more accessible web browsing experience as well.
