    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 ...

    We've talked about it in the past and I'm sure we'll talk about it long into the future: battery life. Today we're going to tackle the subject from another direction. Rather than talk about what you and I can do to try and extend how long our batteries last, let's talk about what manufacturers and OEMs are doing to try and maximize battery life in phones and tablets they make. Make Bigger Batteries Let's face it, we've got two competing specifications here: who can make the thinnest phone, and who has the larger capacity battery. Usually the one who leads in one spec trails in the other. ...

    Last week on the Android Guy Weekly we talked about how batteries are holding our devices back. Our CPUs, GPUs, RAM, screens, and wireless radios are getting more power-hungry, but our batteries aren't making the same technological leaps as the other components. The comments on that episode we very informative and helpful, but a single thread began to stand out from the others: What can I do to make my battery last longer. What was more interesting that the comments were geared more to the lifespan of the battery, not the run-time per charge. We'll tackle that in today's episode of The ...
