Meet the most important tech company you’ve probably never heard of.

Never trust gadget-makers’ claims about battery life. They usually employ weasel words (a machine that alleges to last “up to” six hours between recharges is technically delivering if it runs out of juice in 45 minutes). And they’re racked with fine-print caveats (the battery can last all week if you dim the display to the point of illegibility). That said, you can relax your skepticism just a bit for the new crop of notebook computers coming out this year. Apple’s new 13-inch MacBook Air promises 12 hours between charges—well, “up to” 12 hours, but based on many reviewers’ tests, including my own, it handily manages a full day without a plug. Lots of new Windows-based laptops are offering similarly amazing stats, and I bet many will meet their claims, too. All of a sudden, your days of fighting fellow café patrons for the last available outlet are over.

Why are laptops batteries getting so much better? The nominal reason is the new Intel processor Haswell—the dramatic result of Intel’s yearslong effort to alter its core assumptions about the future of technology. For much of its life, Intel optimized its processors for speed—every year, the chip giant released new ones that were the fastest ever, because it guessed that computers could never get too powerful. For three decades, that bet was correct. Every time Intel’s chips got faster, software makers came up with new uses for them: better games, audio and video editing, faster Web servers. It seemed likely that our thirst for computing power would never be quenched.

But over the past few years, Intel’s assumptions began to unravel. As computers got fast enough for most ordinary uses, speed was no longer a draw—if all you wanted to do was check your email and surf the Web, why would you buy a monster PC? Instead of faster computers, the world began fixating on cameras, music players, smartphones, tablets, e-readers, and tiny wearable machines. These devices weren’t computationally powerful, but they were small, light, thin, and offered great battery life. Intel’s fast, battery-hogging chips just couldn’t work in them.

Instead, almost out of the blue, a rival chipmaker came along to fill the void. It wasn’t Apple, Google, Samsung, or any other familiar tech giant. It was ARM, a small British firm that is the most important tech company you’ve probably never heard of. ARM’s chips sit at the heart of almost every tech innovation in the past decade, from the digital camera to the iPod to the iPad to the Kindle to every smartphone worthy of the name. And it’s only due to competition with ARM that Intel created Haswell. When your laptop goes a full day without a charge, you can thank ARM.

If you’ve never heard of ARM, it’s partly because of its stealthiness: None of the products that use ARM’s technology are stamped with its brand. What’s more, compared to the biggest names in tech, ARM is almost comically tiny. In 2012, Intel and Google each made $11 billion in profit. Microsoft made $17 billion, Samsung  made $21 billion, and Apple made $41 billion. ARM? In 2012, it made $400 million—less than 1 percent of Apple’s take. (The name, by the way, is pronounced “arm,” not “A-R-M.” The acronym once stood for Advanced RISC Machines—RISC being an acronym for a certain chip-design philosophy—but in 1998, the company decided to drop the double acronym. Now, like KFC, ARM officially stands for nothing.)

Despite its Lilliputian scale, ARM’s processors are in everything. The company claims a 90 percent market share in mobile devices. Ninty percent! You almost certainly own at least one ARM-powered thing, and probably closer to a dozen. There’s an ARM in your phone, your tablet, your car, your camera, your printer, your TV, and your cable box. In 2012, manufacturers shipped 9 billion ARM-powered devices; by 2017, the company predicts that number will rise to 41 billion every year.
