Apple's customized battery tech excels at Wi-Fi surfing test
A UK-based electronics testing and recommendation magazine and website, Which, has rated the tablet battery life of various sized tablets -- and found that the iPad and iPad mini ran away with the competition, besting its rivals by very significant scores. While scores were closer between the iPad 2 and the better 10-inch tablets, the Retina fourth-gen iPad model's score was well over 50 percent better than the combined average of the competitor tablets, with all screens set at equal brightness.
Lion still 'king' of battery life among released versions
First, the bad news: three sets of separately-conducted independent tests have confirmed what many users suspected -- the initial release of Mountain Lion contained a bug that severely decreased battery life in the latest MacBook models compared to previous releases. The good news is that those same tests show that the not-yet-released 10.8.2 update, currently in beta testing, may fix the issues -- and possibly provide slightly better battery life than has been previously seen in any OS version tested, going back to Snow Leopard.
Case to more than double existing battery capacity
Mophie is gearing up to release its first battery case for a non-iOS handset. The Juice Pack for Samsung Galaxy S III is claimed to add more than 100 percent to the existing battery life of the Android smartphone, according to Engadget. This could potentially see the handset run for over 21 hours, double that of the 10 hours 20 minutes when used for 3G calls during tests.
Carat checks for power hogs, bugs to improve battery life
Carat, a new app for iOS (Free, iTunes) and Android (Free, Google Play), has been designed to give users a personalized set of recommendations on their app usage to help extend their battery life. Developed by a team of UC Berkeley researchers, the free app collects data in the background and requires a few days of collection before it can offer recommendations. The anonymous crowd sourced data is sent back to UC Berkeley servers where complex algorithms are applied and a userís results compared with others before the recommendations are offered.
Users have to manually watch for power hogs
Google co-founder Larry Page, speaking at the company's I/O developer conference, suggested that there is "something wrong" if an Android handset cannot get through a full day without recharging the battery. The executive was responding to a question regarding the company's plans to address battery life issues on the mobile platform.
Devs claim 3 hours of Flash video playback
Following a video preview of Flash running on a Nexus One, Adobe has rebuffed claims that the software slashes battery life. Several bloggers, including Daring Fireball's John Gruber, observed that the battery charge indicator dropped from the 50 percent level down to 25 percent during the eight minute video. The preview was edited, however, making it unclear how long the team actually used the phone during filming.
iPhone battery criticized
Strategy Analytics has released research that shows battery life as the iPhone's most dissatisfying feature. The buyer analysis firm concluded that the most common owner of an iPhone falls into the 25-44 age group, with a $50,000+ income -- they are also likely employed full-time and over 80-percent own an iPod as well.
iPhone leads 3G batteries
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. PC World investigated several 3G smartphone handsets, showing that the iPhone 3G bests the Instinct, the HTC Touch Dual, and the LG EnV with 5h 38m, the only three others which featured over five hours of talk time.
iPhone praise and concerns
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. Among the acclaimed technologists were Walt Mossberg of the Wall Street Journal, David Pogue of the New York Times, and USA Today's Edward Baig. The three writers noted that the different pricing structure and 3G battery life were two small strikes against the new device, but ultimately considered the upgrade to be a boon.
MacBook Air battery life
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.
Zune Battery Issue
Owners of both the original Zune 30 and the new Zune 80 have discovered that the latest firmware is refusing to properly enter its sleep mode, say multiple reports from Microsoft's official forums. 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.
