Samsung is currently working to recall all the Galaxy Note7 devices it sold in the last month because of the well-known risk of battery failure. Knowing if your Note7 is affected right now is easy—if you have a Note 7, it's recalled. In the future, you might not know for certain when you see a Note7. Samsung's online IMEI check tool is now available to verify if a device is recalled or not. Read More
The MIT researchers-turned-entrepreneurs at a company called SolidEnergy have something you've probably heard before but also something you haven't. A battery breakthrough that will drastically increase your future phone's battery life? We've heard that before. New battery tech that is ready for production within a year? That's new. Read More
The benefit of replaceable batteries is that you can replace them. This effectively doubles your device's battery life. I know. Mind blown.
Batteries can be pricey. Like other forms of phone accessories, you may want to wait for a sale before picking one up.
Oh look, what have we here? Read More
You may have heard the name "Anker" a few times, but haven't really paid attention to what they make. Today is your chance to get acquainted because just about everything Anker makes is on sale via Amazon's gold box deal. There are external batteries, cables, car chargers, earbuds—allthethings.jpg, basically. Read More
LG is sticking to its guns when it comes to offering removable batteries in its phones, but the way it's going about that with the G5 is unusual. All the leaks we've seen thus far show a seemingly unibody device, but now we have a better idea how the battery slides in from a post on Weibo. A user there has posted a picture of the battery and what appears to be the cap from the bottom of the phone. This might be part of LG's rumored "Magic Slot" system.
With gigantic screens and the extra internal space that goes along with them, Samsung's plus-sized flagship phones already offer large batteries: 3000mAh for both the Galaxy Note 5 and the Galaxy S6 Edge Plus. But for some that just isn't enough, and that's where third-party battery supplier ZeroLemon shines. Both phones have sealed battery compartments, but the usual work-around is to build a giant battery into an even more giant phone case. So it is with ZeroLemon's latest offerings: enormous 8500mAh battery-cases for both devices.
The math works out to almost 3X battery life on a fully-charged case, plus the runtime of the phone's internal battery, though the electrical inefficiency of the external battery system probably means it won't last quite that long. Read More
At the 56th Battery Symposium in Japan, Huawei showed off its next generation of quick charging batteries. Huh? Yes, there's a Battery Symposium in Japan, and yes, there have been fifty-five of them in the past. Stay focused here.
Huawei says its new lithium-ion batteries can achieve charging speeds ten times faster than normal batteries. Read More
Are you looking for a ludicrous amount of external battery power? Then look no further than Woot.com today. The electronics section of the site is offering a two-for-one deal on a Limefuel 15000mAh external battery pack for $39.99. That's an almost ludicrous 30,000 milliamp-hours, approximately ten complete recharges of even huge phones like the Nexus 6. Also I guess you could keep one and give the other to someone else. Weirdo.
These particular batteries are pretty standard: they feature two charging ports each, 1 amp and 2.1 amps, plus an LED flashlight and a tiny LCD readout for viewing the battery level. Read More
Square batteries are fine for square things, but the latest craze is round watches, which means lots of wasted space on the inside. That's a bummer when we're already struggling to keep watches running for more than a day. However, LG Chem says it has leveraged new manufacturing techniques to produce hexagonal batteries that can cram as much as 25% more power into a watch.
An external USB-powered battery is not a complex piece of electronics. Generally it has energy input, energy output via a couple of standard USB ports, maybe a few LED lights for measuring the charge, and perhaps a flashlight if the manufacturer is feeling creative. But today's Amazon Gold Box deal includes a battery that can actually start your car. How's that for flexibility? The Anker gadget (an economical brand name we've come to trust) is going for $59.99, $100 off the retail price.
Technically I suppose this is a car starter that can also charge your gadgets via two USB ports (1 and 2.1 amps, if you're wondering). Read More
