Steve Jobs Speaks: Apple’s iPad Enjoys 10 Hr. Battery Life

Already the subject of much discussion, the battery that will power Apple’s highly anticipated iPad has been once again thrust in the limelight. This time, Apple CEO Steve Jobs himself jumped in on the conversation.

A blogger from the “online authority for government IT professionals”-site GCN (Government Computer News) had recently wondered aloud that 10 hrs. of battery life from Apple’s potentially game-changing iPad may have been a bit of a stretch. He e-mailed Jobs to ensure him that he wasn’t calling him a liar, he was just making the point that marketers have a funny way of padding the stats sometimes.

Two hours later, Jobs responded directly – “[...]yes, we are getting 10 hours in 1.5 pounds. Sent from my iPad”

From the iPad itself, Jobs confirms that its owners will in fact enjoy 10 hrs. of battery life per charge. Not too shabby…

The iPad will begin shipping in the United States on April 3.

Solar Vest Battery Charger: Poor, Yet Eco-Friendly Fashion Statement

Solar power has never looked this bad….If ‘going green’ is something that you’re truly serious about, here’s a great way to prove it. What a better way to demonstrate your commitment to living an eco-friendly life than by wearing it across your chest. With the Solar Vest from Chinavasion, you can do exactly that.

Pretty simple concept, very poor sense of fashion. We would also highly recommend these not be worn in airports or near government buildings as one could get the idea that there may be more than just batteries in the vest.

Solar Vest Battery Charger- All yours for $126

-Solar Vest – Canvas Material
-8,800mAh Capacity
-4 Solar Panels
-Multiple Connectors
-5V, 6V, 9V, 12-20V Output

Forget the Battery, Apple to Replace Entire iPad

“If your iPad requires service due to the battery’s diminished ability to hold an electrical charge, Apple will replace your iPad for a service fee.” -Apple-

In what will be quite an interesting move once the highly anticipated iPad makes its way into the hands of consumers, Apple has announced that once the iPad battery goes, they will replace entire device for a service fee in the form of cost is $105.95 per unit, $99, plus $6.95 shipping. That’s right, for $106 you’ll receive a brand new(or possibly refurbished,) iPad in about seven days or so. However, is that necessarily a good thing?

“You will receive a replacement iPad that will not contain any of your personal data. Before you submit your iPad for service, it is important to sync your iPad with iTunes to back up your contacts, calendars, email account settings, bookmarks, apps, etc. Apple is not responsible for the loss of information when servicing your iPad.”

While receiving an iPad that will almost certainly be in much better condition overall doesn’t sound all that bad, not being able to transfer personal information to your new iPad has certainly raised some eyebrows. iPad owners will either have to back-up all of their information, or risk losing it all once the battery ceases to perform. Will this a fair trade-off for a new device?

Cell Phone Powered by a AAA Battery

In an effort to get cellular phones into more hands throughout their country, the Indian mobile phone company Oliver Telecommunications cellular telephone which is powered by a single “AAA” sized battery. The “FrvrOn,” short for “forever on,” is outfitted outfitted with a rechargeable lithium-ion battery just like most other cellular phones. However by creating a phone that runs on a AAA, people in areas where power isn’t readily available are able to stay connected until nearer to a power source.

“We have electrification all across the country but the power supply is erratic,” said marketing manager Ravi Perti. “With our phone, all one needs to do is pack a few extra cells (batteries) if one is traveling in areas where one expects power supply disruptions.”

Perti says the phone can run for up to three hours on the stock lithium ion battery, and another hour on a single AAA battery. Probably wouldn’t be a bad gadget to have anywhere in the world.

Tricks to Keep Your Device’s Battery Going and Going

If you’re a recent convert to smartphones, you’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phone’s battery lasts.

While a standard cellphone’s charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during January’s Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

The answer was not to desperately search for an electrical outlet to recharge the phone (though I’ve done that) or to consider giving up the phone (done that, too), but rather to figure out a strategy to reduce energy consumption while still having it available for essential tasks. Whether you’re using a laptop or a smartphone, the devices can be tweaked to get the most out of its lithium-ion batteries.

Reconsider Your Network

All things being equal, the C.D.M.A. mobile standard used by Verizon uses more power than a G.S.M. network, principally used by AT&T and T-Mobile. If battery life is critical, you might want to consider G.S.M. as long as its coverage meets your needs.

Dim It

The brighter your screen, the more juice you’re using. If you’re in a dimly lit room, turn down your LCD screen’s brightness. If your device has an autodimming feature that detects the light in a room, use it. Similarly, if you use your smartphone or laptop to play music, lower the volume.

If you have a BlackBerry, the company’s holster will automatically turn off the screen when you insert the phone.

Still Going? Energizer Announces Duo Battery Charger and USB Charger Software Problem

The United States Computer Emergency Response Team (US-CERT) has warned that the software included in the Energizer DUO USB battery charger contains a backdoor that allows unauthorized remote system access.

Energizer DUO is a USB battery charger. Included with the charger is a Windows application that allows the user to view the battery charging status. The installer for the Energizer DUO software places the file UsbCharger.dll in the application’s directory and Arucer.dll in the Windows system32 directory. When the Energizer UsbCharger software executes, it utilizes the UsbCharger.dll component for providing USB communication capabilities. UsbCharger.dll executes Arucer.dll via the Windows rundll32.exe mechanism, and it also configures Arucer.dll to execute automatically when Windows starts by creating an entry in the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key..

The issue lies with Arucer.dll, which US-CERT says is a backdoor that allows unauthorized remote system access via accepting connections on 7777/tcp. The backdoor could potentially allow an attacker to remotely control a system, including the ability to list directories, send and receive files, and execute programs. The backdoor operates with the privileges of the logged-on user.

Energizer has discontinued sale of the product, as well as taken down the site where the software could be downloaded.

A Glimpse of the Future? Nokia Developing Self-Charging Cell Phone Battery

While many are turning to solar power as an alternative source of energy, it appears that Nokia has it eyes set on the development of kinetic energy as a potential game-changer for cellular phone batteries. The Finnish mobile device manufacturer has filed a patent in the US for the Piezoelectric Kinetic Energy Harvester, which is a cell phone battery that’s “contained within a first frame that is coupled to a second frame by one or more piezoelectric elements.” The concept involves a battery mounted in a larger frame and isolated from it by piezoelectric element. From this, enough kinetic energy is said to be harvested to “at least partially recharge the device battery.”

“A battery for an electronic device is contained within a first frame that is coupled to a second frame by one or more piezoelectric elements. The second frame is coupled to a device chassis by one or more additional piezoelectric elements. In response to translation and/or rotation of the electronic device, portions of forces induced by the battery mass are transferred to the piezoelectric elements. Electrical energy output by these piezoelectric elements is received in a power controller and can be applied to the battery. Additional device components can also be contained within the first frame so as to increase the total mass that induces forces applied to the piezoelectric elements.”

While the thought of self-perpetuated batteries in mobile phones is quite intriguing, it may be a while before we see the fruits of Nokia’s patent. Still, when considering some of the other cell phone battery patents that have been filed in recent years, the time and resources being put toward developing alternative sources of energy in the mobile phone world will eventually result in a much more eco-friendly product than those currently available.

Dell Inspiron 15 (1564): Powerful and Affordable

I like a lot of Dell’s newer laptops, and I had hoped to like the company’s newly Core i5-enhanced Inspiron 15 (1564 variant). This model has a lush widescreen and isn’t too big, and the glossy shell looks nearly as good as the Apple aesthetic it apes. At about $934 (as of March 9, 2010) when it isn’t on sale, the 1564 is a reasonably priced all-purpose laptop with a substantially more than adequate chunk of silicon at its heart. But it doesn’t give you a lot of ways to get all that power out and onto the screen of your choice, and the keyboard is an uncomfortable mess. Typing this review means that I’m finally, blissfully close to not having to use this keyboard ever again. (Yes!)

The review model I received had the “Ice Blue” finish with the familiar Dell icon in the center. The glossy sections of this machine are fingerprint magnets (no way around that), but they look good. The whole thing measures 15 by 9.8 by 0.8 inches and weighs just under 5.5 pounds. The 15.6-inch widescreen display stretches it out–this is not a laptop you can casually toss into a small bag, but it isn’t a monster either. The left side has USB, VGA, and HDMI ports, plus the ethernet plug. The right edge has the DVD drive, two more USB ports, microphone and headphone ports, and a memory card reader.

Open the laptop, and you’ll find a keyboard that runs the whole length of the machine, a power button, a few status lights, and a touchpad with two buttons. The touchpad is bog standard, responsive and spacious but not quite up to the level of Lenovo’s ThinkPad line. The keyboard is shoved to the left to accommodate an undersize numeric keypad on the right, leaving the whole arrangement cramped and off-center. It’s ghastly to type on, and it gets worse the longer you use it. If you love Dell’s human-interface style, you’re in luck. If you love interfaces designed for human comfort, you’re…less in luck.

Our test model had a Core i5 520M processor clocked at 2.4GHz, 4GB of DDR3-1066 RAM, a 350GB hard drive, and the ATI Mobility Radeon HD 4330 discrete graphics chip. All that power was reflected in an impressive WorldBench 6 score of 105, well above the average range for the all-purpose category. As for video game performance, the 1564 is no gaming rig, but it has more than enough power for a user who’s willing to stay within some reasonable resolution and effects limits. The native resolution of the screen is 1366 by 768, and modern games are playable at that level. You pay for performance in battery life, however: Though I expect most models in the category to reach about 4.5 hours of battery life, the 1564 usually manages about 3.5 hours.

A more serious concern than the amount of power is what you can–or, rather, can’t–do with it. The system’s three USB outs aren’t bad, but with this impressive CPU and discrete GPU, where’s my FireWire, my eSATA, or even my Express Card slot? The 1564 certainly has more than enough power to chew through regular laptop work without flinching. It has just enough oomph to be a capable portable video-editing machine, too. But Dell has provided no good way to get all that content in and out.

Beyond that issue, the screen wouldn’t be my first choice for doing color-sensitive work like video or graphics editing. It has no perfect viewing angle, blacks come across as muddy pools, and the screen is too glossy. The audio is about as mediocre as the display, producing hollow-sounding tunes and issuing a lot of crackling. The speakers can kick out plenty of volume, but Dell clearly opted for quantity, not quality, of sound.

Dell’s built-in software is strongest in the Dell Support Center and Webcam Central apps. The former is a hub for information about your machine, while the latter makes it easy for even the most technophobic computer user to take embarrassing images and videos of themselves. On the other hand, the Dell Dock is still just a semifunctional combination of the Start button’s features and a Mac dock, and Dell DataSafe is merely a constantly running pitch for online storage.

I really wanted to like the Dell Inspiron 15 (1564), but mostly I find myself apologizing for it. Users who love the ergonomically unpleasant keyboard configuration can get a lot of power out of the rig for a reasonable price. But I’d lean toward a more powerful piece of laptop hardware for full commitment to the desktop replacement route, or a slightly less capable machine with better battery life for anyone who is committed to using their system on the go. Maybe the next Dell laptop will be the one I love.

Windows 7 Battery Doubts Remain

A day after Microsoft said it could find no evidence that its Windows 7 operating system drains laptop batteries at an unusually fast rate or issues false alarms about impending failure, users continued to insist there’s an issue.

Find out how to increase availability while reducing data center energy consumption

“I have the battery problem everyone else has been talking about,” wrote “Patel33″, in a bulletin board post to a Microsoft support forum. The user said he and his wife have Toshiba laptops that are identical except for the fact that his runs Windows 7 and his wife has Vista.”Guess what, in two weeks of use my battery is dying and the energy report shows only 15% chargeable. Wife’s is completely fine,” said Patel33.

“Same problem with mine,” wrote forum member “Lagunexxx”, who said the battery on his Asus notebook PC died “within a few days” of his installing Windows 7. Numerous other posts voiced similar problems.

The ongoing reports of Windows 7 battery issues prompted a Microsoft rep to jump into the forum on Wednesday. “For others posting to this thread with battery issues, please contact our support.microsoft.com Customer Support so that we can gather insight into the specific details of what you are seeing,” wrote a support rep named Chris.

The new reports come just a day after Microsoft Windows group president Steven Sinofsky used a blog post to insist Windows 7 does not create battery problems.

“At this time we have no reason to believe there is any issue related to Windows 7 in this context,” said Sinofsky, in a post Tuesday.

“To the very best of the collective ecosystem knowledge, Windows 7 is correctly warning batteries that are in fact failing and Windows 7 is neither incorrectly reporting on battery status nor in any way whatsoever causing batteries to reach this state,” said Sinofsky.

Sinofsky said it’s normal for laptop power cells to start to lose their ability to hold a charge after about a year, and said users who are experiencing trouble should purchase a new battery.

Goldman Sachs Looking to Follow Google, Facebook with Battery-Powered Servers

Following the lead of companies such as Google and Facebook is never a bad idea. No slouch in its own right, the global investment banking and securities firm Goldman Sachs is looking to do just that as it seriously contemplates moving to custom web servers outfitted with on-board batteries.

“I think the trend you’re going to see is servers with batteries,” said Goldman Sachs vice president David Schirmacher. “That’s one of the areas we’ve been focusing on. Everyone knows what Google has done with their custom servers. That’s not pushing into the mainstream manufacturing market. We have some teams working on this.”

In a recent post by Data Center Knowledge, the brief history custom-fitting servers with batteries shows why this system is so beneficial for corporations that feature and rely on large data center operations. Facebook, for instance, says it expects using on-board batteries with its servers to reduce the energy loss during power distribution from the current 35 percent to about 15 percent, while Google, which uses a 12 volt battery in its design, reports exceptional energy efficiency data for their data centers.

“The use of an on-board battery on web servers allows data center operators to create a more efficient power path through the facility. In most data centers, a large centralized UPS system stands between the utility power grid and the servers. When there is a grid outage, the UPS taps a large bank of batteries (or in some cases, a flywheel) for “ride-through” power until the generator can be started. The AC power from the grid is converted into DC power to charge the batteries, and then converted back to AC for the equipment, with each conversion resulting in small power losses.” -Data Center Knowledge-

While it remains to be seen if this is a trend that others will follow, this type of server/battery combination has already seen results so significant that others who rely on large data centers will eventually need to consider this type of set-up. If it’s good enough for Google, Facebook, and Goldman Sachs….
