Another Nokia Lumia 800 battery update coming in two weeks

Nokia said on Twitter Wednesday that a second software update will roll out to Lumia 800 devices over the next two weeks. It is largely expected that the update will help fix the poor battery life that has plagued some, but not all, Lumia 800 users. Nokia has already addressed the battery issue, which limits the capacity of the battery, and has even recommended that those with the problem send their devices in for replacement phones. More →

Samsung promises all-day battery life from new smartphones in 2012

Samsung promises all-day battery life from new smartphones in 2012

Samsung understands that battery life is a big problem when it comes to smartphones. The company is looking to fix that, however, promising that all Samsung smartphones coming out this year will last all day on a single charge with average to moderately heavy use. “When you wake up to when you go to bed, we don’t want you feeling anxiety about your battery life,” Samsung VP of product innovation Kevin Packingham said in an interview with CNET. Motorola recently announced the DROID RAZR MAXX, a variant of the DROID RAZR featuring a massive 3,300 mAh battery. Samsung will also move to larger batteries, though the company plans to focus on optimizing different aspects of the phone as well, according to Packingham. The changes will come from the way a phone acts when searching for Wi-Fi, to the way it connects to 4G LTE networks. Packingham acknowledged that Samsung “wasn’t quite there yet,” in regards to the company’s first 4G LTE smartphone, the DROID Charge. Despite these upcoming improvements, Packingham noted that power users will always face problems with battery life.

Next-gen iPad may feature double the battery capacity of iPad 2

Apple will launch a new high-end iPad model in early 2012 featuring a battery that includes more than twice the capacity of the current iPad 2 battery. Citing anonymous sources from within Apple’s supply chain, DigiTimes recently reported that Apple’s upcoming next-generation flagship iPad will feature a new 14,000 mAh battery, as will a new mid-range iPad model. The new power pack will feature more than twice the capacity of the 6,500 mAh battery currently used in Apple’s iPad 2. DigiTimes also reported late Wednesday that Apple’s 2012 iPad lineup will include three models: a low-end iPad 2, likely available at a discount compared to current pricing, a mid-range next-generation iPad and a high-end model. The new mid-range and high-end models will also reportedly feature an upgraded 2,048 x 1,536-pixel displays with dual-LED backlighting. More →

Nokia to issue Lumia 800 battery fix early next year

Nokia’s European support team has issued an official statement to those who have a Lumia 800 with poor battery life. “We immediately started to investigate these reports and can now confirm that while the battery itself is fine, a software problem on certain variants is limiting the phone’s ability to access the full battery capacity,” a Nokia representative wrote on the support forums Monday. Michael explained that the battery life issues are only the result of a software flaw and, as such, Lumia 800 owners can expect a software patch that fixes the problem early next year. Lumia 800 users who do not want to wait that long can contact Nokia and request a replacement handset. Hit the break for Nokia’s explanation of how to find out whether or not your Lumia 800 is affected by the bug. More →

Batteries that charge 10x faster and last 10x longer just 5-years out, scientists say

Batteries that charge 10x faster and last 10x longer just 5-years out, scientists say

Fat battery pack accessories may soon be a thing of the past. Scientists at Northwestern University are tweaking lithium-ion batteries to last 10 times longer and charge 10 times faster than the battery technology used today, BBC reported recently. Better yet, the new tech could be on the market in just 5 years. Oddly enough, it appears that poking “millions of minuscule holes” that are just 20-40 nanometers wide, and changing the movement and density of lithium ion cells, helps to add battery life and speed up the charging process. A prototype phone battery in Northwestern’s labs can be fully charged in just 15 minutes and it lasts an entire week on a single charge, BBC said. Dr. Harold Kung, the lead scientist on the project, explained that the speed and density of lithium ions can be changed using different materials during the battery’s manufacturing process. “Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today,” Dr. Kung said. Unfortunately, battery life begins to decline quickly after about 150 charges with the technology in its current state.  More →

Apple seeds iOS 5.0.1 beta to end users to test battery life improvements

Apple has already released two beta versions of its iOS 5.0.1 software to developers, but now it is beginning to seed the software update to several end users through AppleSeed as well. The update is expected to offer improvements to the Siri voice engine and should address issues many users have been having with battery life. Participants who choose to test the new iOS build will not be able to revert to an earlier version after upgrading, but they will be able to upgrade to the final patch when Apple releases it in the next few weeks.

iPhone 4S battery drain could be result of time zone bug

iPhone 4S battery drain could be result of time zone bug

We have seen a number of reports suggesting that the Apple iPhone 4S has a software bug that has resulted in poor battery life. iDownloadBlog says that adjusting the time zone settings on the iPhone might help alleviate the issue. Reportedly, a bug within iOS 5 forces the phone’s location tracking feature to remain active far more than it should, which in turn drains the phone’s battery too quickly. Users can manually turn off the automatic time zone setting by navigating to Settings > General > Date & Time and toggling “Set Automatically” to “Off.” Other users, however, have suggested that the time zone function has nothing to do with the poor battery life, which has left some people fighting to squeeze more than just a few hours of battery life from their iPhone. Apple has yet to release an official patch to address those with poor battery performance, but we suggest adjusting your time zone settings to see if that helps in the meantime. In our independent tests, we’ve found that disabling the setting does improve battery life to some degree, though none of our units were as bad as many users are reporting even with the setting enabled.

iFixit reveals inner workings of iPhone 4S in new teardown

The crew at iFixit has given the iPhone 4S its proper tear-down, revealing the phone’s inner workings and hardware. iFixit noticed that the battery offers an extra 0.5 WHrs over the one found in the iPhone 4, which is likely the reason Apple is able to advertise an additional 1-hour of 3G talk time on the iPhone 4S compared to its predecessor. The phone is equipped with a Qualcomm RTR8605 radio, an Avago ACPM-7181 power amplifier and of course a dual-core 1GHz Apple A5 processor, which has been downclocked to 800MHz. Be sure to hit the jump for a few more images of the iPhone 4S teardown. Deliveries of Apple’s new smartphone begin on Friday, and in the meantime be sure to check out our hands-on with the iPhone 4S. More →

Details on new battery suggest thinner, lighter iPad 3 design

Details on new battery suggest thinner, lighter iPad 3 design

Apple has secured Simplo Technology Co. and Dynapack International Technology Corp. to supply battery packs for the vendor’s upcoming iPad 3 tablet, Taiwan Economic News reported on Tuesday. According to the report, the new batteries will be thinner and lighter than the modules used in Apple’s current iPad 2 models, and Apple’s cost for the power packs will apparently jump by between 20% and 30% as a result. The report also states that Apple’s new iPad 3 batteries will feature a longer service life than the previous-generation packs used in the iPad 2. A thinner, lighter battery could mean Apple is conserving space for a new beefier Retina Display, or it could mean Apple is slimming down the iPad 3 case from the iPad 2’s already-svelte 0.34-inch-thick profile. Apple is expected to launch the iPad 3 early next year. More →

Apple laptops can be hacked to self-destruct; flaw to be detailed by hacker next month

Apple laptops can be hacked to self-destruct; flaw to be detailed by hacker next month

How’s this for an undocumented feature? Apple’s newer MacBook, MacBook Air and MacBook Pro notebooks have a security flaw that can allow hackers to remotely prevent the batteries from charging. Better yet, hackers can exploit the same flaw and remotely cause batteries to explode. Apple laptops’ new “smart” battery technology is intended to provide added control over power management, and it does just that. Unfortunately, it also gives hackers added control because the microcontroller chip that ships in recent Apple laptops can be accessed remotely using a default password shared by each and every notebook. Charlie Miller, the security expert who discovered the vulnerability, plans to showcase the flaw next month at the Black Hat security conference. There, Miller will show that he is able to access the battery controller remotely and cause it to refuse a charge, or even heat up until it catches fire and explodes. “These batteries just aren’t designed with the idea that people will mess with them,” Miller told Forbes last week. “What I’m showing is that it’s possible to use them to do something really bad.” Thankfully, the security expert also intends to showcase a fix for the flaw, which Apple will hopefully implement as soon as possible.

BlackBerry PlayBook battery life may have been weakened by recent OS update

BlackBerry PlayBook battery life may have been weakened by recent OS update

According to a report from CIO, BlackBerry users who installed RIM’s latest update for the tablet’s QNX operating system are now experiencing weakened battery life. The recent 1.0.3 software update introduced BlackBerry Messenger (BBM) and video chat to the device, but it also appears to have had a substantial impact on battery life, possibly reducing it by 11% or more. RIM addressed the issue by suggesting that users accept the new license agreement for video chat, which may drain the battery if left unchecked, and the company also suggested that users fully charge and discharge the PlayBook battery several times in order to restore full function. Many users report that neither proposed solution has has an impact on the weakened battery life, however. More →
