There’s been a lot of talk surrounding the Samsung Galaxy S26 Ultra’s battery size. Some rumors claimed the S26 Ultra’s battery will be larger than the Galaxy S25 Ultra’s, which is 5,000 mAh, while others said it will be the same. Now, a new leak from China claims the Galaxy S26 Ultra will pack a slightly larger battery. According to the source, the Samsung Galaxy S26 Ultra will pack a 5,200 mAh battery. That’s hardly an upgrade, but it’s a step in the right d...

As an auditor of battery manufacturers around the world, University of Maryland mechanical engineer Michael Pecht frequently finds himself touring spotless production floors. They’re akin to “the cleanest hospital that you could imagine–it’s semiconductor-type cleanliness,” he says. But he’s also seen the opposite, and plenty of it. Pecht estimates he’s audited dozens of battery factories where he found employees watering plants next to a production line or smoking cigarettes where...

If you’re anything like me, you probably have a pile of aging external batteries. Up through this year, I’ve had countless 10,000mAh bricks — the classic “big battery” size through most of the 2010s — along with a handful of smaller cells designed to offer something a little more pocketable and portable.

Since the launch of the iPhone Air and Apple’s MagSafe battery pack, I’ve been trying to find which MagSafe battery is the best for most people. So I got on Amazon, ordered a bunch of them, and I’ve been testing each one on an iPhone 17. There are five batteries in the competition, all at various price points and marketed as a 5,000mAh battery size. I’m also including the Apple MagSafe battery, but it’s only built with a 3,133mAh battery. These are the challengers: UGreen Magnetic –...

Image: Michael Crider/Foundry I had my eye on the Asus Zenbook A14 from the moment I first saw it at a promotional event, thanks to its super-light build, unique finish, and insane battery life. But I wasn’t in love with the $1,000 price when it finally arrived at Best Buy. I waited for it to hit $600 before I pulled the trigger—that’s my laptop in the photo right up there. Today, you can get the same laptop for even less at just $549.99. You can read all about the Zenbook A14 in PCWorld�...
