Smartphone Users Wasting Hundreds On Unnecessary Contracts

By | Apple, ATT, Droid, Google, iPhone, Verizon | No Comments

A new study says that smartphone users are overpaying for their service by several hundred dollars each and every year. The study, put together by Billmonitor, notes that people are overspending primarily because they’re on contracts that wildly overshoot their needs. People have a habit of signing up for contracts with far more voice minutes than they use, and it’s primarily for this reason that smartphone users are paying much more than they need to. In other words, double-check your statement to make sure you’re on the right contract.

But it’s not only that smartphone users are paying for more voice minutes than they use. Now that data-heavy services (the usual suspects like Spotify, etc.) are commonplace, smartphone users often go over their monthly data limit. Pass the limit, per per megabyte. It’s a cruel world. The study found that the average smartphone user eats up some 133MB of data per month. That, of course, will only increase as users discover and use more data-heavy apps like the MLB app.

The study also says that people are afraid of “bill shock” (freaking out at the unexpectedly high cost of your monthly bill), hence their tendency to overshoot their contract requirements.

Future iPhones/Pods charged with your heartbeat – experts say

By | Apple, Droid, iPhone, news | No Comments

Apple's colorful iPod Nanos.

“Nanogenerators” powered by your heartbeat could replace conventional batteries in about five years, according to chemists.

In a world dominated by 4G smartphones, touchscreen tablets and portable laptops, finding ways to keep everything charged can be a nightmare and a losing proposition. What if we could power them from anywhere while doing almost nothing at all?

Dr. Zhong Lin Wang and his team of researchers at the Georgia Institute of Technology have developed tiny nanogenerators that use small movements to generate enough power.

At the National Meeting & Exposition of the American Chemical Society, Wang’s team demonstrated the ability of their milestone device, using it to power LCD screens and even transmit a radio signal.

For Wang, his nanogenerators are the solution to our outlet-tethered mobile existence — an idea he made clear at the chemistry conference. “This development represents a milestone toward producing portable electronics that can be powered by body movements without the use of batteries or electrical outlets.”

Wang’s new device is thousands of times more powerful than previous generations. “If we can sustain the rate of improvement, the nanogenerator may find a broad range of other applications that require more power,” he said.

“Our nanogenerators are poised to change lives in the future,” Wang said. “Their potential is only limited by one’s imagination.”

Nanogenerators work using zinc oxide (ZnO) nanowires — “piezoelectric” gizmos that can generate an electric current when strained or flexed. This means that almost any kind of movement – walking, a heartbeat, wind, even rolling tires — can generate electricity.

The next step is to boost the potential power output, Wang said. “Additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering larger electronics, such as an iPod or charging a cell phone.”

“While a few volts may not seem like much, it has grown by leaps and bounds over previous versions.” Wang expects his nanogenerators to be in stores within 5 years.
