Sprint Samsung Galaxy S4 Gains HD Voice Icon, Security Enhancements

It was nearly a month ago that Sprint announced the nationwide availability of HD Voice, and since that time, a number of handsets have received the requisite software necessary to take advantage.

A notable omission from many upgrades, however, has been any kind of HD Voice indicator, which makes it rather difficult to tell in what areas the feature is available.

Fortunately, manufacturers have been adding iconography retroactively, most recently Samsung for the Galaxy S4(more…)

Stanford Researchers Develop New Battery Tech That Could Massively Increase Capacity

While virtually every component that makes up a smartphone has advanced by leaps and bounds over the past few years, power tech has largely stagnated - the G3 may pack a mind-bogglingly high-resolution screen, but its maximum battery capacity represents the limit of viability, at least without sacrificing thinness.

Thankfully, scientists at  Stanford recently achieved what some are calling the “holy grail” of battery design: a stable lithium anode. The anode, if further refined, could lead to cheaper and more efficient battery designs for every electronic that relies on lithium batteries.  (more…)

Qualcomm is Ready to Bring You LTE Direct, Battery-Friendly Contextual Awareness

Lots of apps nowadays – from Google Now, to Foursquare, to Keep – rely on locational awareness (more commonly referred to as “geofencing”) to serve contextually sensitive information, such as the number of nearby restaurants and friends. That’s all good and fine, but those features typically rely on a combination of GPS, WiFi, and Bluetooth signals to function, which means using them requires sacrificing power.

Qualcomm thinks it may have a solution in LTE Direct. The technology, a device-to-device discovery service, piggybacks on LTE spectrum to help smartphones and tablets – thousands of devices at a range of around 500 meters, to be precise – to exchange information.  (more…)
