We're all a little curious about why a battery might explode, so let's talk about it. Exploding battery talk is something you can't escape right now, thanks to a problem with the Samsung Galaxy Note 7. It's good discussion to have: the more people talk about it, the less likely it is for a child to get hurt from a battery failure. As much as we hate to see a product we like experience safety...

Naztech Power Bank with Adaptors
With the ever growing number of devices that people are carrying around with them, there is more need than ever for ways to keep said devices charged. Some people, like myself, carry around at least one usb power brick with them so that they can charge their devices throughout the day. This effort is useless if you are somewhere without outlets or if you want to charge on the go. Thankfully...

A new research paper details the efforts of a team at Stanford University who are looking to create a lithium battery that, if successful, could lead to much longer battery life for smartphones and tablets, but it could take several years for that research to yield practical products.

TYLT ENERGI 2K makes sense for iPhone users, not so much for anyone else

TYLT ENERGI 2K Travel Charger
The TYLT ENERGI 2K travel charger, on paper, makes sense. It's got prongs that fold out of the body and straight into a wall charger, so there's no mucking about with USB cables and separate charging warts. Just plug the battery into the wall and charge away. We get that. And if you're an iPhone user, that makes sense. Who wants to carry around a microUSB cable that you might well have no other...

Sweet, sweet science is on its way to finding a cure for how lithium-ion batteries (like the one in your phone) lose their ability to hold a charge over time. Researchers at Lawrence Berkeley, Brookhaven, and Stanford have found a pattern to the erosion that happens at both anode and cathode ends of the battery, when previously it was assumed the erosion was uniform. The salt that forms at the...

Galaxy S5 extra battery kit
Samsung's extra battery kit gives you a second battery for your GS5, a protective case and an external charger If you've got a phone with a removable battery, like the Samsung Galaxy S5, you might as well put it to good use. Sure, you can use an external USB battery pack with just about any mobile device, but that doesn't beat the instant refill you get by swapping out a dead battery for a...

Nexus 5 camera
How does the Nexus 5's battery stand up after a few days of real-world use? Battery life is one of those areas of smartphone performance that’s difficult to quantify. Synthetic tests rarely reflect real-world performance, and it takes time to get a feel for how a new phone stands up. We’ve been using the Nexus 5 as our daily driver for the past few days — just about long enough to get a good...

We've got a new iteration with the HTC One Max, one that includes a built-in battery for a little extra juice. The Power Flip Case serves as case to protect the body of the...

Two new battery technologies to power a future lineup of devices from LG Following up on statements that it has already begun producing 6-inch curved displays, LG is also announcing that it is ready to produce curved batteries. Building up on previous advancements in battery technology that yielded the "stepped battery" in the LG G2, the LG Chem division of the company is now making the move...

LG stepped battery
Two trips to New York City in two weeks — one for Motorola, and another for LG, and one common theme: Why waste space inside the phone when you could fill that void with a little extra battery volume. Enter the "stepped battery," and it's a simple enough idea. Instead of a single, rectangular-shaped battery, you've got one with a small "step" — and little bit of a hump that gives you a little...

We're still a couple of weeks out from LG's New York launch event for its new G2 smartphone, but we already know quite a bit about the device, thanks to LG's teasing and a number of recent leaks. And the latest G2 leak, which came to light through a (now deleted) post on a Korean forum, shows us the the front face and back of the device. The front is a familiar sight — all screen, with virtual...

GoStick II.
We hooked up with the folks from BTI recently in Las Vegas to take a quick look at their GoStick II portable battery. This is one of those "need-it-right-this-second" solutions that'll give you an extra charge in a pinch via microUSB. The GoStick II has a 2,600 mAh capacity, so you'll only get about one extra go with this thing.  The GoStick II is nicely designed. It's about as big as a roll of...

Qualcomm has seemingly out of nowhere released Snapdragon BatteryGuru, an app to help users with devices that have Snapdragon processors make the most out of their batteries. The app has some pretty lofty promises, and with support from the same manufacturer as your processor you'd hope that it would be able to help with battery life a notable amount. So can Snapdragon BatteryGuru solve the...

Mophie Juice Pack for Galaxy S3
A few weeks ago we reviewed the Mophie Juice Pack for the Samsung Galaxy S3. Mophie PR was a little surprised that we came away not all that impressed, given that we've sung the praises of its iPhone Juice Pack. In fact, Mophie was concerned that because we'd purchased our first two units from resellers on Amazon (separate resellers, actually), we might well have received counterfeit Juice Packs...

The Mophie Juice Pack for the Galaxy S3 doubles your phone's battery life - but at quite the cost in this case   I have no qualms about admitting my lust for the iPhone's Mophie Juice Pack battery case. My wife's used one with her iPhone, and it's a great combination of extra juice and protection in a form factor that doesn't kill the overall feel of the phone. We've looked at a couple of...

While that same retailer is still taking pre-orders for the item without an expected shipping date, Amazon Germany has gone one better.  According to the item's listing on Amazon.de, the Samsung Extended Battery Kit will become available on January 5.

Droidax Power Pack for Samsung Galaxy S3.
Here's a quick update on the Droidax Power Pack for the Samsung Galaxy S3 that we reviewed a couple months ago. In our original review, we noted that the case didn't seem to fit properly up top, and so the phone could potentially come loose -- possibly damaging the microUSB plug on the case, or the port on the phone itself. Either way, that was no bueno. Droidax has sent us a redesigned top half...

We'd never turn down more juice, but is 2500 mAh on a 5-inch device really that low? Yesterday we brought you the first photos of HTC and Verizon's 5-inch, 1080p Android smartphone, codenamed "DLX," along with a full list of specifications. By any standard, the DLX is a super-high-end phone, packing a quad-core Snapdragon S4 CPU -- generally considered to be the fastest SoC around -- and the...
