Laptop battery life itself has “gotten better, but not tremendously so,” said Baker. The use of more energy-efficient components, such as a solid-state drive vs. a hard drive, in laptops, for example, helps.

Last fall, HP said its HP EliteBook 6930p achieved a 24-hour battery life on a single charge, and Dell unveiled several new models that have a 2710p battery run time of 19 hours.

MIT Professor Gerbrand Ceder and graduate student Byoungwoo Kang are working with the material in lithium-ion batteries so that the time it takes to recharge such batteries would be seconds instead of hours.

In an interview with Alan Boyle,  Kang said the technology being developed would be well-suited for the bigger DM3 battery used in plug-in hybrid electric vehicles, but may also work with smaller products, such as laptops and cell phones.

Samsung’s 8-megapixel Pixon camera phone, due out this month in Europe, will also come with an LED flash, 16x zoom and autofocus. There’s no word on pricing yet, but phones with higher-capability cameras are pricey, often starting at $300 and up.

“Can you take a photo with a camera phone that takes as good a picture as a digital camera? That’s starting to be the case if you limit yourself to certain really high-end camera phones 4710s battery ,” said Avi Greengart, Current Analysis research director for mobile devices.

Most consumers don’t go on three-day business trips, and if the laptop’s moving, it’s often just moving from one room to the next,” he said. “It doesn’t move that far and is always near a plug.”

Chamberlain notes that laptops with non-removable  HSTNN-OB89 batteries are not only “sleek, skinny, smooth,” but are also “more impervious to dust, moisture and other factors if you’re going to use them in tough environments like outdoors, or in vehicles.”
