In setting up a new lab, a group of research students at Purdue University were inspired to come up with a way to put the huge amount of packing peanuts they were receiving to good use. At the suggestion of Professor Vilas Pol, the researchers developed a potential new eco-friendly application for rendering the packaging waste into lithium-ion battery anodes.Lithium-ion batteries have two electrodes, a cathode and an anode. The anode harnesses the lithium ions (which are contained in an electrolyte solution) during recharging. Today most lithium-ion battery anodes are made of graphite, however... Read more...
When Nvidia unveiled its new GeForce 800M mobile family a few weeks ago, it talked about a new set of improvements and innovations coming to laptops with through the GeForce Experience program. In the future, applications would have the option to dramatically improve battery life by limiting in-game frame rates as well. Nvidia claims that its upcoming profiles will do more than simply limit a game's frame rate, but it identified that option as one of the most useful ways to squeeze better battery life out of a system while gaming. We decided to test the idea and see just how much of a difference... Read more...
Apple iPhone 4 and 4S owners haven't much time to celebrate the release of iOS 6, which introduces a bazillion new features, along with a nifty panoramic picture mode. Unfortunately, for some users, all the goodness of iOS 6 has come at the expense of battery life. Yep, here we go again. It seems like shortened battery life is always an issue with an Apple product at any given time, and in this particular case, iPhone 4 and 4S owners have taken their complaints to the Cupertino company's support forum. "Some is massively eating battery life in 6.0. I have a 4S, and I had great battery life. 8AM-5PM... Read more...
Intel has selected Integrated Device Technology (IDT) to develop an integrated transmitter and receiver chipset for the company's Wireless Charging Technology (WCT) based on magnetic resonance technology, it was announced today.  In other words, WCT is one step closer to becoming a reality, which is exciting news whether you're hardcore geek or just a fan of gadgets. Yes, there are wireless charging platforms out there, but as Intel's Dan Snyder explains in his blog post, WCT isn't limited to inductive charging. You won't need to plop your smartphone or other gear on a special charging mat,... Read more...
When Apple rolled out Mac OS X 10.8 Mountain Lion, the company claimed the operating system introduced over 200 new features to the Mac platform, but reduced battery life wasn't supposed to be one of them. Nevertheless, a large number of users have taken to Apple's support forum to complain about major dips in battery life after installing Mountain Lion. "I upgraded to Mountain Lion and now my battery life is about half of what it was before upgrading," the opening post reads. Others quickly chimed in with the same complaint. One Mac user said he used to "easily" get a full day of use on his 13-inch... Read more...
Developers have access to a new beta version of iOS 5 -- version 5.0.1 -- that's supposed to fix battery life issues reportedly plaguing some iPhone and iPod touch users who installed Apple's latest and greatest mobile OS. iPhone 4S owners have been particularly vocal in voicing concerns that their shiny new smartphone is giving up the ghost well before their previous iPhone device used to, even though their usage habits are the same (we haven't run into this issue ourselves). What gives? According to the release notes, Apple discovered and fixed a bug affecting battery life. What exactly that... Read more...
You know, processing speed seems to be skyrocketing, but is anyone stopping to think about the impact on battery life? When it comes to notebooks and mobile phones, speed is clearly king, but only if that speed doesn't totally murder one's battery life. Some of the newer LTE phones can barely last an entire day with average use, and that's upsetting some folks at the University of Michigan. Big Blue scientists have developed a new subconscious mode for smartphones and other WiFi-enabled mobile devices could extend battery life by as much as 54 percent for users on the busiest networks. University... Read more...
At the end of February, Nintendo will finally launch its 3DS handheld console in Japan, followed by a worldwide release in March. As those release dates near, Nintendo has begun serving up additional details about its 3D-capable gaming device, including battery life. According to Nintendo's recently updated product page, you can expect just 3 hours and 30 minutes of run time in 3D mode. If you're playing regular DS titles in 2D mode, things are a little better with 5 to 8 hours of rated run time, but both of these figures are approximate values and will vary "depending on the brightness of the...

Is the battery revolution upon us? Based on all the broken promises we've seen of revolutionary advancements over the past decade, we're guessing not, but we're certainly hopeful that EcoloCap Solutions is onto something. We've said for years now that battery life needs to improve in a big way on notebooks, and PC makers just need to be more honest about real-world figures from the start. But really, we just need better batteries overall--batteries that last longer and cost less. EcoloCap has just received preliminary results of the independent tests of it Nano Lithium Battery conducted by Exponent,... Read more...
If you upgraded your old notebook to Windows 7, you may have seen a new message surrounding the battery life meter that never appeared in Vista or XP. Many users began to think that Win7 was incorrectly reporting that their battery needed replacing, and the noise got so loud that Microsoft had no choice but to investigate on their end.The message that users were seeing alerted them that they should "Consider Replacing Your Battery," and many felt that their battery was perfectly fine before upgrading to Windows 7. Of course, it's hard for anyone to swallow the fact that their battery may in fact... Read more...
Battery life has been a huge issue around these parts. Particularly when it comes to notebooks, it always feels like manufacturers are giving us rough life estimates that are nowhere near accurate when compared to real-world figures. From R/C cars to notebooks to cars, there's no question that batteries are necessary in the world of technology, but they're also amongst the most annoying aspects due to their inability to stay charged for a remarkably long time and their tendency to degrade over time. Not to mention they're bad for the planet, expensive and unreliable. Batteries may be the perfect... Read more...
It's a topic we cover often because it's near and dear to our hearts. It's battery life, and it's finally starting to get the attention that is has long deserved in the industry. We've seen article after article point out that battery life claims on laptops are flawed in one way or another, and AMD's own Pat Moorhead is stepping forward this week with some facts and figures to back that up. For whatever reason, AMD has taken a strong, vocal stance against shoddy battery life claims. They've had it with PC manufacturers pumping out notebook after notebook with crazy claims, ones that they can't... Read more...
Back in the day, it was somewhat unusual for a company to issue revamped versions of popular machines. Instead, they'd simply pop out another model so it was quite clear that an update had taken place. These days, consumers seem to "get" that technology changes frequently, and that models are updated from time to time with new hardware.Such is the case with MSI's drop-dead gorgeous X-Slim X340. The ultraportable's name hasn't changed, its design is the same and even that attitude is still in place, but a newer edition definitely brings a few twists to the table. As of now, MSI is offering the X340... Read more...
Battery life has taken on a life of its own here at HotHardware, and considering that many iPhone 3GS users are bickering about shorter-than-expected lifespans, this app couldn't arrive at a better time. Showcased now in Apple's App Store, 'Battery Go!" measures and displays the remaining battery life on one's iPhone or iPod touch right down to the minute.Developed by CollegeKidApp.com, the software also has four large icons that display how long you could surf the web, chat on the phone, listen to tunes or watch video with your remaining life. A novel addition, for sure. The program costs just... Read more...
