Your phone’s power usage can reveal where you’ve been

When you think of smartphone location tracking, both legitimate or otherwise, and you will most likely think of technologies that directly relate to locations, like GPS, WiFi, or even Bluetooth. But a group of researchers from Standford University and Israeli defense group Rafael are proving even something so innocent sounding like your phone's battery consumption can be used to track your movements. The good news is that it's not exactly as easy or as informational as those more dedicated sensors. At least not yet.

Keep Android apps in check, save your battery life

Keep Android apps in check, save your battery life

Last time we shared how you can significantly prolong your iPhone 6's battery life without gimmicks or accessories. It all boils down to corralling your apps and keeping them under your control, never letting them do stuff without your consent, like access data or incessantly trying to grab your attention. You can do the same for your Android smartphone, with almost exactly the same steps, of course in different places. And we're going to show you how, plus some other steps you might have to take on Android.

Brio Family-safe Smart Power Outlet hands-on

Brio Family-safe Smart Power Outlet hands-on

Successfully funded through Kickstarted on the 18th of December and already ready to show off here in January at CES 2015, that's the Brio smart electrical outlet. What you're seeing here is a replacement for your old outlets, taking up no more power - and in most cases LESS power - than you've used before. This plug-in system activates only when a real cord requiring power is plugged in, removing the danger of a human shock in the process. No more zaps for little Billy - not even with a fork.

I’m getting two-day battery life from my iPhone — Here’s how

I’m getting two-day battery life from my iPhone — Here’s how

If Santa brought you an iPhone for Christmas, you’re likely still in love with your new iDevice. Of all the knocks on any iPhone, battery life is among the most notable, with the small-ish battery of an iPhone tending to need a charge daily. In my experience, though, the iPhone 6 can last quite a bit longer than your work day and commute home. I’ve even been able to take it on weekend jaunts without needing to plug it in. Here’s how.

Ocean current energy system in the works by Toshiba and IHI

Ocean current energy system in the works by Toshiba and IHI

The teams as IHI Corporation and Toshiba Corporation have begun work on an ocean energy power generation system. They've been selected by Japan's New Energy and Industrial Technology Development Organization (NEDO) as co-researchers in their new system for "Research and Development ("R&D") of Ocean Energy Technology - Demonstration Research of Ocean Energy Power Generation". The team have been working on research and development since 2011 on a Next-Generation Ocean Energy Power Generation (Underwater Floating Type Ocean Current Turbine System) - demonstration research is coming up next.

Sweat-powered smartphones tapped with digital tattoos

Sweat-powered smartphones tapped with digital tattoos

In a turn of events very similar to what we’re experiencing with the VivaLnk Moto X digital tattoo collection, researchers in California have found themselves working with a temporary tattoo which allow human sweat to generate power. This device uses temporary tattoo sticky paper with a flexible lactate sensor imprinted upon it. From there, it’s time to sweat.

Raspberry Pi Model B+ has more slots, less power demand

Raspberry Pi Model B+ has more slots, less power demand

The Raspberry Pi Model B is getting another facelift and no, this isn't a Raspberry Pi 2, and all that is implied by that major name change. Instead, the B+, as the name would suggest, is a very incremental improvement over the existing Model B, giving makers and hackers more connectivity options but retaining the same core and keeping compatiblity with the existing software and peripherals.

Intel Labs paper to reveal details of energy efficient graphics chip

Intel may still have a throne over at the PC world, but in the mobile land it still has to conquer its own territory. Part of Intel's problems lie with a graphics processor that is unfit for mobile devices, but the chip maker might already have a solution ready for some real-world testing.

Boosted batteries teased from Li-Ion visualization research

Boosted batteries teased from Li-Ion visualization research

Longer lasting, higher capacity, and cheaper rechargeable batteries could be in the pipeline as scientists finally figure out exactly what's going on inside, potentially opening the door to increased electric car range and smartphones that spend less time plugged in. The microscopic imaging techniques, developed by researchers at the US Department of Energy's Pacific Northwest National Laboratory, are expected to make it possible to examine what's happening within a live lithium-ion battery, particularly around areas of chemistry which so far power research has struggled to understand and refine for longer-lasting gadgets.

Powerslayer smart charger aims to eliminate wasted energy, hits Kickstarter goal

Powerslayer smart charger aims to eliminate wasted energy, hits Kickstarter goal

Devices that need charged on a regular basis, such as smartphones and tablets, are apt to be left plugged in for long periods of time, even if the battery itself has reached it full charge. Though charged, there is still an energy draw that is taking place, which results in wasted power, and, though not much on an individual scale, it adds up when multipled by millions of gadgets. That is where the Powerslayer comes in.

NASA shelves fuel-efficient tech, effectively slashes outer planet exploration

NASA shelves fuel-efficient tech, effectively slashes outer planet exploration

NASA this weekend all but abandoned a money-saving technology due to a lack of money. You read that correctly. The space agency's budget woes are so suffocating that it can't even get the funding to develop ways to make missions more efficient. In this case, the efficiency would have been massive: the Advanced Stirling Radioisotope Generator (ASRG)--the program that just effectively got the ax--would have let many space missions require just one-fourth the fuel they currently need.
