The smartphone market revolves around one question: how do you fit all-day access to all of a consumer's favorite applications and services comfortably into one hand? (The tablet market? Two hands.) The rest is commentary.

The electronics that enable faster performance, higher-speed data, better video and gaming, a more vivid and detailed screen, are moving at the speed of Moore's Law. The lithium ion (Li-ion) pouch … Read more

One possible solution to resurrect a dead phone resides in Sony's latest portable CycleEnergy USB charger with a built-in hand crank, due in Japan on June 20 for 8,000 yen ($100).

After Apple's iOS 5.1.1 update was released last week, several users began reporting that their iOS devices had taken a significant battery life hit.

While the issues are not common to most users, it appears as though some iPhone and iPad owners found that the battery life they had come to expect was not apparent after updating to iOS 5.1.1 using Apple's over-the-air updating.

If you find your device is not getting the battery life it once was, a few troubleshooting tips provided by Apple Support Communities user sbaily4 could be of help.

In today's show, we're buying status updates, finding a new route and building a new game addiction:

Would you pay $2 to get your Facebook status message seen by more people? It's something Facebook is testing in New Zealand. (And tell me your two-cents on the issue via Tout!)

If you know anyone living outside the U.S. who wants a tablet, laptop, camera, or smartphone from the States, it's best to send it to them before May 16.

As of next week, the United States Postal Service, or USPS, is banning all international shipments containing lithium ion batteries, which many electronics have (see the full list below).

The most likely reason for the ban is that if lithium ion batteries are fully charged or not correctly stored or packed, they can catch fire or combust -- something obviously best to avoid while shipping. … Read more

That seemingly ordinary iPad 2 that Apple is selling for $399 has actually been modified internally in ways that, in some cases, can yield better battery life, according to a report.

Along with the new third-generation iPad, Apple in March began selling a lower-priced, $399 iPad 2.

And an A5 built on … Read more

You see that battery meter dwindling down to zero. There's a knot in your stomach. You'd pay anything just to squeeze another 10 minutes from your phone.

Your panic is justified. Not only does a dead phone battery cut you off from communication with the outside world, but it strips you of your contact book as well. There was a time when I could remember close to a dozen phone numbers off the top of my head. But today, I can barely remember my wife's number without the aid of my phone.

Fortunately, there are a number … Read more
