Inverted rendering

We know we just suggested installing the Chrome browser, but if you find the stock browser more to your taste, here's a tip that could save you some battery life and eye fatigue. From the browser's Settings page, tap "Accessibility," then hit "Inverted rendering." That options  switches the colors so black becomes white and vice versa -- in theory, that makes the screen darker overall so the battery isn't working to pump out so much light. It's easy on the eyes, too, especially when you're reading at night. Once you've inverted the rendering you can drag the contrast slider up and down to get things looking just right.
