Smartphone, laptop battery life to see 10X increase

Smartphone and laptop batteries could soon see a ten-fold increase in both the charging speed as well as battery life. Researchers at Northwestern University have developed a lithium-ion electrode that enables conventional lithium-ion batteries to get ten times more capacity and would still run five times as efficient as current batteries after 150 charging cycles or about a year of use.

iPhone 4S iOS 5.0.1 battery fix falls short

iPhone 4S iOS 5.0.1 battery fix falls short

Apple's iOS 5.0.1 update looks to have been a smooth first test of the company's new OTA distribution system, but feedback on whether it has addressed widespread battery problems is less positive. Apple Support Forums are awash with owners complaining that the issue - where an iPhone running iOS 5 sees faster than expected battery drain - remains or, in some cases, has apparently been made worse with the new patch.

iPhone 4S battery issue points to Setting Time Zone switch

iPhone 4S battery issue points to Setting Time Zone switch

If you're one of the masses of iPhone users that've upgraded to the iPhone 4S in the past few weeks, you may well have been experiencing some battery issues - today we may well have the answer as to why. As we've seen this past week, quite a few people have had what they've described as less than stellar battery life with their iPhone 4S, and this weekend we've not only been handed a possible solution, we've tested it for ourselves, and what do you know, it appears very much to work: just switch your Setting Time Zone switch to off!

Apple contacting customers regarding iPhone 4S battery issues

Apple engineers have been contacting customers directly in an attempt to diagnose and resolve the battery issues that have been plaguing many new iPhone 4S owners. Apple Support Communities forum has a growing thread of users experiencing shorter battery life than expected on the iPhone 4S. The thread has now reached over 100,000 views and more than 1,300 replies all recounting similar experiences with the new Apple device.

Galaxy S II NFC capabilities inside, dormant for now

Galaxy S II NFC capabilities inside, dormant for now

If you've got either an AT&T or a T-Mobile Samsung Galaxy S II and were hoping to work with Google Wallet in the near future, you might well be in luck. Have a look under your battery cover and you'll find the three sweetest words a mobile payments seeker can ever read: Near Field Communication. It's not been highly publicized yet because plans aren't publicly solid, but take a closer look in at least one public press release and you'll see it, clear as day: NFC enabled.

Samsung Series 7 CHRONOS notebook PC Hands-on [Video]

Samsung Series 7 CHRONOS notebook PC Hands-on [Video]

A lovely set of laptops is what Samsung is presenting next here at this year's Pepcom Holiday Spectacular 2011, the Samsung Notebook Series 7 CHRONOS. This laptop comes in two sizes, one of them a 14-inch profile, the other a 15-inch profile, both of them with bigger displays than you've ever seen before in such a small set of chassis. What we get to see here isn't so much about the insides - things like the Battery Life Plus tech which keeps 80% of the cell's original capacity in a normal life cycle (this providing up to 15,000 charging cycles), instead our presenter from Samsung shows off the uniqueness in the display technology and the coolness of the chassis - well done since we've already also got an IFA 2011 look of one of the two of these notebooks in some nice photo detail as well.

Lithium Jelly Batteries are safer, thinner, and cheaper than conventional lithium batteries

Lithium Jelly Batteries are safer, thinner, and cheaper than conventional lithium batteries

Researchers from the University of Leeds have announced that they have devised a new type of battery that is safer, thinner, and cheaper to build than current lithium batteries. The new battery uses a jelly to replace the volatile liquid electrolytes used in current lithium batteries. That means that if the battery is punctured, the electrolyte will not leak.

New sensor tech uses vibrations to charge its battery

New sensor tech uses vibrations to charge its battery

I have long said that one of the technologies with the most promise to change our world is battery tech. The batteries that last longer and charge faster are key elements to improve everything from smartphones to cars. A company called MicroGen Systems has been developing cool battery tech for small, low power sensors that generates power for its on-board battery by harnessing vibrations. These batteries are ideal for low power sensors like the ones in late model cars that power the TMPS system that monitors tire pressures.

Cornell and MicroGen car sensors and instruments harvest power from road vibrations

Cornell and MicroGen car sensors and instruments harvest power from road vibrations

On a normal vehicle with a combustion engine, the power needed to operate the various instruments inside the car is not that big of a deal since you have power as long as the fuel holds out. On an EV or hybrid the less drain on the battery, the longer the driving distance so in these vehicles shedding all the power drain possible from the batteries is a big deal.
