This one is simple – the more browser tabs you have open, the more work your device is doing. The effect is more noticeable on a computer than a phone or tablet, as forgotten tabs mount and the fans start to kick in (always a sign of heavy-duty processor activity), but even mobile devices tend to spend energy and memory keeping Web pages ready to view. To increase battery life and decrease stress on other components, kill old tabs.
