Internet Explorer 8: Best Browser for Your Battery?

What's The Best Browser for Your Battery?
The War of the Web Browsers mostly takes place on one battlefield: speed. And while Google's Chrome is the clear winner on that front, there are other skirmishes -- like those over add-ons and resource usage -- of which Firefox is the clear victor.

Until now the only victories that Internet Explorer could claim were 'Largest Install Base' and 'Most Vulnerable to Hackers.' But tech blog AnandTech decided to pit the browsers against each other based on how quickly they drain your laptop battery. Surprisingly, IE8 wins with the longest Web surfing time.

Why Laptop Batteries Don't Last as Long as Claimed

More Accurate Battery Test for Laptops in Our Future?
Anyone who has shopped for a laptop knows that a manufacturer's estimated battery life is estimated pretty liberally. Usually, the numbers are based on a test called MobileMark 2007, which measures how long a computer's battery lasts under conditions that are, to be polite about it, completely unrealistic. The screen is set to 20-percent brightness, Wi-Fi and any other wireless tech shut off, and all apps are turned off. As the New York Times said, "it turns a computer into a dimly lit clock."

The problem is that nobody simply sits in front of their laptop staring at a blank screen. In fact, most users treat their laptops just like a desktop PC. Most users listen to music, instant message, and browse the Web (all at the same time) with the brightness pumped up to 100-percent. It's no surprise that when manufacturers claim battery life is around six hours, it .

MIT-Developed Batteries Can Charge in Seconds



Some big brains at the Massachusetts Institute of Technology have developed battery technology that could change the way we charge up our cell phones, cameras and other devices, according to the MIT News.

The technology involves a change in the channeling of lithium ions through -- you guessed it -- lithium ion batteries. Created by MIT Professor Gerbrand Ceder and graduate student Byoungwoo Kang, the new battery design allows for lithium ions to speed around the surface of the battery in a way MIT News likens to cars driving around a city's expressway loop. While the new design allows particles to enter the battery's center from numerous exit ramps, conventional chargers have all those ions driving straight up Main Street. This increased efficiency in regards to time and energy allows these smaller, lighter batteries to be recharged in mere seconds, according to Ceder.

Get NiMH Batteries for Your Camera



If your camera takes AA batteries, you should know that regular alkalines die in a fraction of the time that Nickel Metal Hydride (NiMH) types do. For the best possible battery performance, look for a rating of 1850 mAh or higher. And, while you're at it, buy rechargeable versions instead of landfill-clogging disposables.

New Dell Laptop Has 11 Hours of Battery Life

The machine translation is pretty weak, but Dell's 12.1-inch (1,280 x 800 pixel) Latitude XT2 looks to have just made its first tentative steps in a global launch. The video posted after the break comes courtesy of Korean site, AVING, where the convertible tablet was apparently just released. Pinch to zoom and two-fingers swipes... yup, it's in there. 11-hours of battery (6-cell plus battery slice) and DDR3 memory (max of 5GB!) too in a chassis just 2.5-cm (0.98-inches) thick. Click through for the video while we track down the official specifications that already seem to be aligning with the unofficial specs leaked earlier.

Student's Tech Promises 12x the Battery Life In your iPhone, BlackBerry

Feeling the hurt of endlessly dying batteries on your BlackBerry (or iPhone, if that's what you're into)? Atif Shamim, a PhD student at Canada's Carleton University might have the medicine for that pain of yours. He's cleverly hacked such devices, removing all the wires that connect the electrical circuits to the antenna, and developed a module for the connection to operate wirelessly. The result, he estimates, is that his modified devices use almost 12 times less power than they normally do -- which of course means longer battery life. A paper about the device has won an award at the European Wireless Technology Conference, and Shamin has filed for a patent in both the US and Canada. There's no indication of when we might start to see tech like this on actual commercial devices, but we're pretty sure plenty of companies are going to want to get a hold of this technology like, yesterday.

Chinese Mobile Phone Has Two -Year Battery Life

Chinese cell phone with two-year battery life.

Battery life is often the determining factor when we buy consumer electronics products. How does a cell phone with two years of stand-by time sound to you?

A new phone out of China promises just that, giving you two years of stand-by time and two to three days of active talking time -- all without plugging the phone into the charger even once.

You may be thinking this device, Solo Mobi model number ZJ268, would be nothing more than a big battery with a keypad, but the handset actually has Bluetooth support, slots for two SIM cards, keypad AND handwriting input, and MP3 playback capability. The Solo Mobi also has plenty of standard phone applications like calendar, task list, and (of course) a contact list.

The 32800 mAh battery is rated by the manufacturer to operate for 666 days in standby mode, which blows away anything else we've seen on the market.

As best we can tell from the manufacturer Web site, the basic cost of the phone is $128. According to the specifications, it does come with a charger -- but why would you need one?

The good news is that if you can get your hands on one -- either by going to China and buying one or finding it for sale online -- you'll be able to use it with ay T-Mobile or AT&T Wireless SIM card.

Top 11 Ways to Make Your Cell Phone Battery Last Longer

Cell phones have come a long way in terms of features and styling, but the issue of battery life, or having enough of it, remains strong. Yes, you can keep your battery juiced up for days if you don't talk on the phone ever, but what's the use of that?

Luckily, all hope is not lost -- with a quick adjustments here and there, you can extend the battery life of your phone by hours and sometimes even days. We've compiled a list of tips and tricks to keep your phone battery running longer -- take a look, follow a few, and you'll never have to say "sorry, my phone battery died" again.

Turn your cell phone off to save battery life

Turn your cell phone off.

Sure, it might seem obvious, but when was the last time you actually shut off your phone when not using it? Well, do it next time, and you'll see just how much longer your battery lasts. When you're asleep, while you're in a dead cell phone reception area, or, the next time you're at the movies....Next time you find yourself in a theater as the previews start, try turning your phone off instead of putting it on silent. You shouldn't be checking your phone during the movie anyway.

Best Phones For Long Battery Life

Some days, we all just like to talk on the phone a lot. We also sometimes forget to charge our phones before we leave the house. And let's face it, carrying our cell-phone-charger around with us all day (or overnight) is often impractical. So what phones are ideal for the sort of person that often finds themselves in charger-less jams? Take a look at our roundup, in which we picked ten standard phones (i.e., non-smart-phones) that have impressive battery life, both for talk and standby modes.



The latest version of the Motorola V195s has now been updated by T-Mobile to include Yahoo! and AIM messaging, Bluetooth connectivity, and longer-lasting battery life. T-Mobile also includes the convenient My Faves free frequent calling program, so you can use the eight hours of talk time wisely. The phone also has up to 17.5 days of standby time.

Battery and Screen Upgrades for iPhone

iPhone Battery, Screen Get UpgradesIf you're the type who likes to gab for seven or eight hours at a time on your cellie and thought that the iPhone's measly five hours just wouldn't cut it, rejoice, because you're now officially out of excuses for ignoring Apple's latest when it drops in two weeks. Apple has announced that iPhone users can expect eight hours of talk time from a single charge, six hours of Internet surfing, or some combination of the two. That impressively out-paces just about every other smart phone on the market, like the popular Samsung BlackJack, which clocks in at 5.5 hours. However, given that you can buy a BlackJack from AT&T for just $75 right now -- $524 less than Apple's product -- you'd better be buying the iPhone for more than just its battery life.

Fortunately, there's been another announcement: Also upgraded from earlier specs is the iPhone's screen, which instead of plastic will be made of glass -- something rarely seen in a mobile device destined for pockets and purses. The screen is said to be more scratch-resistant than plastic, something scuffed iPod owners will be glad to hear. Whether that screen can handle getting sat upon remains to be seen.
