    Editor's note: In the gulf between iPhone releases and in the run-up to the next Windows Phone resurrection, the ratio of Android to non-Android phones in our review inventory continues to rise. As a result, this piece is written from a predominantly Android-centric perspective. Everybody wants awesome smartphone battery life. Whether you’re addicted to the latest power-draining augmented reality game or just trying to get through a day of texting and talking, the panic moment is a familiar one: mid-afternoon, no charger in sight, and a pop-up dialog warning you that you’re 15% away ...

    By USB or by wall outlet, our gadgets receive energy and store it in their batteries. Once they're unplugged, they're immediately powering through your day. That is, if they can last as long as you do. And in the case of wearable technology, where battery capacity only goes so far as the technology inside of it and the limited physical footprint, sometimes they don't. With discharge cycles lasting anywhere between 18 hours and seven days, we're not excited with having to deal with what's still widely considered as an accessory to a smartphone rather than a dedicated device in its own ...

    Whether you use a tablet, phablet, or phone, and regardless of what OS powers it or which brand is stamped on its backside, we all have one thing in common: our devices all have batteries that always need recharging. Power bricks come in all shapes and sizes. Some may feature a quick-charging standard, others may be the run-of-the mill chargers that simply get the job done. Regardless, they all require a power outlet - and there never seems to be one of those around when we need it. What we need is a compact, portable, charging station that we can take anywhere, uses power from the ...

    The most advanced mobile hardware in the world, easy-to-use, feature-packed, and compatible with all the top-shelf software you could hope for, isn't going to do any of us any good if it runs down its batteries too quickly. As the wearable market matures, and we squeeze powerful hardware into smaller and smaller form factors, having enough battery capacity to meet demand becomes a rowing problem. Plenty of companies are working hard to advance current battery technologies, and one of the latest firms to get involved is none other than Google. Google's battery efforts started out as it ...

    One thing all of us have in common is the fact that all of our devices will eventually run out of power and need to be charged again. Doing so is a relatively simple process: plug your charging cable into a computer, wall wart, or specialty outlet - then wait. Back in the early days we had relatively small battery capacities and charging our phones didn't take too long. Today we have devices with thousands of mAh capacities that take all night to charge, but typically don't last all day! The solution from Apple and Samsung was to provide some "signaling tricks" which enabled their charges ...

    When it comes to cellular phones, removable batteries are nothing new, even the very earliest phones had a battery that you could remove and replace. Historically, this was more a necessity than a convenience. Until the last few years, battery technology suffered from various limitations that necessitated their ability to be removed and replaced fairly frequently. For their size, energy capacity wasn't all that great. Charge times were slow, and discharge rates were fast. Over the years, these batteries even developed a "memory" that reduced their capacity due to the buildup of tiny ...

    Every time a new smartphone or tablet comes out we ache to see more cores, faster frequencies, better graphics, more RAM, and increased storage space. All this comes at a cost: run time. For years we've been asking for improvements in battery life to better meet the needs of our always-on, media-intensive lifestyles. Why can't battery technology improve at the same pace as other electronics? If the science holds true, we might be poised to see such an advancement thanks to a special formulation of lithium and sulfur. Capacity The batteries in our smartwatches have around 300 mAh capacity ...

    For the better part of the last five years, battery life has been an issue. I've never managed to get the alleged four hours of screen-on time some forum users claim, and I've rarely been able last a full day with just about any non-BlackBerry smartphone. It happens, but it's rare. "It's just the way or how much you use your phones." That's what everyone always tells me, but that's not the problem, I assure you. Just because I'm a "tech blogger" doesn't mean I use my phones endlessly. It's quite the opposite, actually. I have countless devices, all of which get a fairly even spread of use, ...

    CPUs, GPUs, RAM, and even storage space all seem to be headed in the right direction: more! Thickness and weight are headed in the opposite direction: thin and light. What's stuck in the middle? That's right, your battery. Batteries are interesting things. They store energy, exactly how they do that has evolved over time -- albeit slowly. There are many kinds of energy out there: solar energy, kinetic energy, nuclear energy, potential energy, hydro, wind, heat, pressure, rotational, chemical, and more. No, those aren't all the same "kinds" of energy, but it illustrates that the topic is ...

    (Updated 02 April 2014 to add HTC's comments at bottom.) Sometimes, all you need is a phone. Not a digital assistant, not a pocket internet tablet, not a gaming platform. Of course all of those things are nice, and the enhanced features smartphones bring to bear have become essential to millions around the world. But thanks to the realities of battery endurance and processor capabilities, most of today's smartphones offer a variation on the same promise: "From the moment I come off the charger until the moment I lose power, I will be a smartphone. Nothing less." With the unsubtly-named ...

    At a time when batteries keep getting bigger and bigger, you'd think that Apple would lead this trend since the biggest complaint that all iPhone users share, is their hatred for its battery life. The irony is that Apple has only grown the iPhone's battery 12% in the last seven years, when compared to Samsung which has almost tripled it. Apple clearly has a problem to fix, and a new patent sheds some light into where it'll focus on next. The patent is called “Inferring user intent from battery usage level and charging trends” so sadly we're not talking about a new battery, nor a ...

    One of the biggest challenges that wearable-tech manufacturers face is how to power such a small device for a decent period of time. Google Glass isn't the best when it comes to battery life, and so is the Galaxy Gear. Now if there's one device that we've generally praised for its battery life, even though not a wearable is the LG G2, and rumors have it that its technology will power the iWatch. Lots of reports had Apple using solar batteries to power the iWatch, but it turns out that these batteries can only provide one tenth of the battery life that a regular lithium-ion battery can ...

    After you've made your decision and have picked up your very own smartphone, phablet, or tablet, you're going to want to pick up a couple accessories. First off you'll want a case, next you'll want some way to charge it while you're on the go. Cases come in all shapes and sizes, but your recharging options usually require a power outlet of some sort, whether it's in the wall or in your car. What if you could combine the two? That's the idea behind HTC's extended battery case, the HTC Power Flip Case for the HTC One max. The complication with integrated batteries is that they're not ...

    Earlier today Verizon, the biggest mobile service provider in the United States, announced three new smartphones from Google/Motorola under the Droid brand: the Droid Mini, Droid Ultra and Droid Maxx. The latter of which promises to bring massive battery life. Sure, sure, it's got a 10-megapixel, 1080P-capable camera, a 5-inch screen, 2GB RAM, 32GB storage, a 1.7 dual-core CPU running quad-core graphics, wireless charging, and is topped off with LTE. What I'm really interested in is the battery: 3500 mAh, and capable of running 48 hours without being charged. That's massive! Many other ...

    Nobody likes a cheapskate. It's why we have fun derogatory labels like "tightwad" and "skinflint" for those friends of ours who insist on dividing the bar bill by how many mozzarella sticks they actually consumed, rather than by the cost of the plate. Whatever other merits they might have, penny-pinchers just aren't fun to have around. That's no less true in the case of huge multinational corporations than with people. But where a cheap social friend is pretty easy to jettison when he gets annoying, it's a little harder to make up for the shortfalls of dealing with a cheap company. ...

    Sadly, battery life is one of the main concerns when it comes to buying a new gadget. Manufacturers are following, to the letter, a trend which makes our phones and tablets thinner and thinner while sacrificing battery life. It also just so happens that today's devices are extremely powerful with specs we never thought possible five years ago. All of the above seem to leave us with beautiful and thin hardware that often times doesn't make it by the end of the day under heavy usage conditions. If there were smartphones and tablets back in the day, there surely would have been a Murphy law ...

    We all know how important batteries are in our modern electronics. They're also becoming an increasingly vital part of our vehicles. For people in both camps, the latest news from Toyota is disheartening: Li-Ion batteries have a "memory effect". Ni-Cad Batteries When the traditional, land-line telephone evolved from a corded beast into a clunky -- but wireless -- beast, there was much cause for celebration. The battery technology of the day was Ni-Cad (Nickel Cadmium). Batteries based on this technology were used in everything from cordless phones to satellites orbiting the planet. There ...

    We didn't expect to run the Weekly with a skeleton crew two weeks in a row - and it's a good thing we didn't have to. Mere minutes into this week's Tony-and-Michael-only podcast, Taylor Martin arrives to save us from the spectre of a fun, but low-energy, two-man show. In its place: jokes, laughs, and a lot of industry insight you're gonna wanna put your ears on. We talk phone batteries that can jump-start your car, what place Twitter has in music, whether we should be excited about Motorola's X phone or Nokia's aluminum Catwalk, and the strengths and weaknesses of Windows Phone, Facebook ...

    One of the main concerns while using a smartphone (and why not, a tablet) these days is battery life. We're happy when our beloved device makes it through the day so we can charge it once again overnight. However, batteries, as we know them today, might soon be replaced with new "microbatteries", thanks to researchers at the University of Illinois. What are microbatteries? Let the press release do the talking: "the most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start ...

    Let's be honest. Battery life, in general, sucks. "Oh, but Display X is 30 percent more efficient! And Processor X consumes 25 percent less power! And it has a 2,500mAh battery!" I got my smartphone roots from the BlackBerry camp, back when BlackBerry – then-Research In Motion – was running the show. Among at least a dozen other models, I carried a BlackBerry Curve 8330 for nearly three years. Even today, it's one of my favorite phones I've ever owned – not because the display was great, the fixed camera took 3.2-megapixel shots or because it had Wi-Fi. (Yes, Wi-Fi was a feature of ...

    Dear OEMs, we, your loyal customers, have been patient long enough. You've given us some really great smartphones and tablets over the years. Your designs are becoming more practical with every iteration, without shedding their aesthetic beauty. We appreciate that, and thank you. Your batteries, however, have got to change. We recognize that your devices are getting faster and thinner, but we can't use them as long as we should be able to. Face it, a smartphone that only lets you use it for 4 hours isn't very "smart". In fact, it's pretty silly, if you ask us. Of course that's not what ...

    1080p displays. On smartphones. I never thought I'd see the day, but it's here. Call the front desk; I'm checking out. No but, for real: around these parts, the notion of full-HD resolution -1920 x 1080- on a smartphone screen has for months prompted a range of reactions, from skepticism to disbelief to glee. Listeners of the Pocketnow Weekly podcast can sometimes hear that entire range in one sitting: pixel-density enthusiast Brandon Miniman is keen on the absurdly high-density panels, while I often profess not to be able to tell the difference. Anton D. Nagy, Joe Levi, or Jaime ...

    Electricity has always been a thing of wonder, but like most technological advancements, it's had its challenges and even a fight for what standard to adopt. Thomas Edison developed what would become the first commercially available electrical power transmission using direct current (DC). One of the drawbacks of DC is its relatively limited range due to loss as distribution lines stretched further away from the power plants. Eventually power plants were created in neighborhoods and business districts to overcome the loss, but the plants were large, somewhat noisy, and generally ...

    Since I'm somewhat of a penny-pincher I tend to look at all of my purchases from a perspective that's a little different than other people. Let me start off by breaking the bad news to you: smartphones are disposable goods. They aren't intended for you to use for ten years like your washing machine or cook-stove. They're simply not "durable", but that makes things sound a little worse than they actually are. If you want to make your phone last, what do you need to consider before you sign that contract or drop hundreds of dollars on it? Stylistic Considerations The best phone in the ...

    We've heard about flexible displays for quite a while. Most of us have envisioned screens that roll up or fold away. Although that may be possible in the future, it's probably not what we'll see right away. Since the Nexus S, Samsung has been working on curved displays, which they called the "Contour Display". Its younger brother, the Galaxy Nexus, also has a curved screen. That's not entirely true. Though the glass is curved, the "screen" is not, and the backs of the devices are decidedly flat. Samsung's YOUM design replaces the glass sheets used in traditional OLED screens with a ...
