All Those Open Browser Tabs Really Are Killing Your Laptop's Battery

By Gizmodo on at

There's a tonne of info on the web. You're never going to read it all, but you want to, so your browser has fistfuls of open tabs waiting for that rainy day when you'll want to read a two-month-old article that's no longer relevant to anything. But have you ever wondered what all those tabs are doing to your battery life? Wired's Rhett Allain did, so he measured it for Firefox, Chrome and Safari.

The bottom line is this: on Allain's MacBook Pro, 100 tabs decreased battery life by one hour, while (hypothetically) 24,000 tabs would drain the battery completely in just one minute. The full article has great graphs and some imposing-looking formulas, and you should really open a new tab and read the whole thing. [Wired via Tested]
