July 14 - 7:35pm EDT   While Apple CEO Steve Jobs' concerns about 3G's impact on the iPhone's battery life were valid, the iPhone 3G still maintains a longer-running battery life than other popular competing mobile devices, including the new Samsung Instinct.

July 9 - 12:30am EDT   The iPhone 3G's official launch on June 11th is just over two days away, and several industry heavyweights have already offered their opinions on Apple's next generation device, offering mostly praise, peppered with a few criticisms.

February 7 - 6:55pm EST   The MacBook Air's touted five-hour battery life is an almost acceptable measure of the ultraportable's abilities, while enthusiast site Mac on Air has performed a full take-apart of the laptop. According to tests performed by AnandTech, the MacBook Air is capable of running for four and a quarter hours with normal web browsing, while playing MP3s in the background. The test was conducted by browsing 20 web pages, spending 20 seconds per page, and looping music in the background. This test was designed to emulate standard usage, as one would experience taking notes in class or using the Air during their daily commute. [full story]

While the handhelds are supposed to enter a low-power mode when idle to preserve battery life when not in use, many are finding that the players continue to operate at near full power. In many situations this almost completely saps the battery when left overnight, users complain. Only models with a hard drive are affected, as Zune 4 and 8 devices (including Electronista's review unit) enter sleep mode properly. [full story]
