On Tuesday, the ultimate nerds over at iFixIt published a full teardown gallery of Apple’s new white unibody MacBook laptop that is in turn replacing the low-end US$999 white polycarbonate MacBook notebook.

Some of the major changes include:

- Polycarbonate unibody construction.

- Display featuring LED backlighting.

- A multi-touch glass trackpad.

- Integrated battery.

- No more FireWire or IR port.

- No external battery indicator.

- No Mini-DVI port, replaced by a Mini DisplayPort.

iFixit has highlighted several interesting aspects of the new design:

-The new battery is only 5 more watt-hours than the previous version’s yet it adds two hours of run time, meaning the machine is markedly more efficient.

-The battery is actually lighter than the older model.

-Unlike the earlier model, AirPort and Bluetooth share the same board, and all three antenna cables route into the display, meaning a possible improvement in Bluetooth range.

-The MacBook has exactly the same GPU and CPU as the baseline 13″ MacBook Pro.

Since a picture’s worth quite a few words, take a gander at the video:

Apple Inc. on Tuesday announced an updated, unibody version to its low end MacBook notebook. The new model, available immediately, is still covered in white polycarbonate but features the same unibody construction and bright LED-backlit screens as Apple’s other laptops, as well as the same glass multi-touch trackpad found in the MacBook Pro line.

According to Macworld, the new 13.3″ MacBook still retails for US$999, but is powered by a 2.26GHz processor. It also features 2GB of 1066MHz RAM, a NVIDIA GeForce 9400M graphics chip, and a 250GB hard drive.

The new notebook weighs in at 4.7 pounds compared to 5 pounds for the old design and now features a non-swappable battery. Apple says that will boost battery life for the MacBook to seven hours, up from five hours in the previous model; it also means users will have to pay US$129 for replacement batteries from Apple. As a result of the battery change, the bottom of the laptop has no feet—instead, the entire bottom surface is rubberized, save for eight screws.

The redesigned MacBook case introduces at least one other change from the previous model—the FireWire 400 port is gone and Apple’s MacBook Pro offerings are now the only Apple portables with FireWire ports.

Albeit Apple is not openly acknowledging the issue, it’s taking the “shy kid” approach to reaching a solution. Per iPhone Blog, Apple is apparently seeking feedback from iPhone users over claims that the recent iPhone 3.1 Software Update is draining batteries.

Short battery life has been a concern since the introduction of the iPhone 3GS amongst many users, despite Apple promising improved performance at June’s Worldwide Developers Conference.

Apple said the iPhone 3GS would deliver 9 hours of use on Wi-Fi, 10 hours of video playback and 30 hours of music on a single charge, about a 30% upgrade to the iPhone 3G.

However, a recent teardown by iFixit noted that the iPhone 3GS’s battery was just 6% more powerful than the battery in its predecessor.

Recently, the company has contacted a number of users on Apple’s discussion boards who have posted negative comments asking for feedback. A list of 11 questions – covering e-mail, push notifications, Wi-fi, Bluetooth and application use – is being sent out reports The iPhone Blog.

The note also contains an attachment which, when double-clicked, installs what looks like an unsigned profile, which apparently enables Battery Life Logging on the iPhone.

Once enabled, the iPhone will sync power logs back via iTunes, and they ask that those logs be sent back to Apple reports the The iPhone Blog.

The blog notes this isn’t the first time Apple, via AppleCare, has contacted iPhone users after posts on the company’s discussion boards.

It is not known what percentage of iPhone owners might be experiencing the problem.

Yesterday, accessory provider NewerTech announced the release of its Intelligent Battery Charging Station, a peripheral designed to charge and condition the batteries used by Apple’s 13″ and 15″ unibody MacBook and MacBook Pro notebooks.

The unit features two bays (one that charges while the other charges and conditions) and NewerTech claims that by conditioning the battery, you can get longer runtimes and better lifetimes from your laptop batteries. The charger retails for US$150 before shipping and handling.

iPhone 3GS Users Noticing Poor Battery Life on Handset

In spite of Apple’s claims that the iPhone 3GS boasts “longer battery life”, some users are complaining that the new handset actually has less battery life than the previous model.

Per The Apple Core and a recent iFixIt teardown, the company noticed the the 3GS battery is 6% larger than the iPhone 3G battery, leading many to suspect that iPhone OS 3.0 may be the culprit.

ComputerWorld followed up on this by noting that users have been reporting worse battery life on all iPhones since the day the iPhone OS 3.0 was released:

“After updating to [iPhone] 3.0 the battery life is very short. It consumes 5%-10% an hour,” claimed an original iPhone user identified as “ukfasthands” in a message posted on Apple’s support forum June 17.

If you’re afflicted you’ll most likely have to wait until Apple releases iPhone OS 3.1, or if we’re lucky, some battery improvement could come with the security update that’s been promised for the end of July. In the mean time, try implementing some of the following iPhone battery savings tips, including:

1. Minimize use of location services
2. Turn off push notifications
3. Fetch new data less frequently
4. Turn off push mail
5. Auto-check fewer email accounts
6. Minimize use of third-party applications
7. Turn off Wi-Fi
8. Turn off Bluetooth
9. Use Airplane Mode in low- or no-coverage areas
10. Adjust brightness
11. Turn off EQ
12. Turn off 3G

Mac OS X 10.6 (Snow Leopard) to Offer Warning for Near-Dead Notebook Batteries

While the immediate charge on a Mac notebook’s battery has been available for years, Mac OS X 10.6 (Snow Leopard) users will be able to see when their batteries are nearing the end of their useful lifespans.

According to AppleInsider, the Mac OS X 10.6 build offered to Worldwide Developers Conference sports a feature in which clicking the battery icon in the menu bar now shows a new, one-word “battery condition” summary in addition to the energy for the current charge and the power source.

When the battery has been used often enough that it ‘s losing capacity, the icon is overlaid with an exclamation mark warning and the battery condition changes to “poor” — both signs that the pack is due to be replaced. While not every condition is known, Snow Leopard presumably reports varying degrees of battery status when the pack has only been moderately used or is like new.

Though Apple has yet to document the reasons behind the change, the most logical explanation is simply that the company’s decision to seal in most notebook batteries makes it more important to have an early notice that a battery is near failing.

Apple has lately been paying closer attention to battery life on all its devices and with iPhone OS 3.0 will add a numerical percentage to the iPhone’s previously icon-only battery indicator.

With only hours to go before Phil Schiller’s keynote address at the 2009 Worldwide Developers Conference, a couple of interesting details have emerged.
According to Daring Fireball, the third-generation iPhone is code-named “iPhone 3GS.” The code name could tie into the Apple IIGS, which shipped in 1986.
The other interesting rumor is that battery life on the new iPhone is 15-20% longer than the iPhone 3G. This will have to be seen and tested, but would prove to be an extremely welcome change if true.
If you have any ideas as to what to expect from the keynote, let us know.

Scientists Look Towards Ferroelectric Transistors for Instant-On Notebook Technologies

Researchers have apparently developed a technology that could allow notebooks to wake up instantly from shut-down states without draining battery life, as is commonly seen today.
According to Macworld UK, researchers have built ferroelectric material (which is usually found on smartcards) onto silicon, which could allow certain transistors to retain information after power is shut off. Scientists from Pennsylvania State University, Cornell University and Northwestern University are involved in the project.
The new findings could save users time by instantly booting laptops to an active and ready state when shut down.
“It would be instant-on, meaning as soon as the power comes back on, your computer would be in exactly the same state it was when you turned it off and ready for action,” said Darrell Schlom, principal investigator and professor at the department of materials science and engineering at Pennsylvania State University.
Quick-boot capabilities are enabled in Notebooks and most mobile devices, though many are unable to recreate shutdown states. As a result, notebooks usually never reboot back to their shutdown state, unless they are in sleep mode, which drains battery power. In essence, ferroelectric materials could wake up laptops from sleep mode, but without drawing any battery power.
The research could pave the way for a new generation of lower-power, higher-speed memory devices, Schlom said. For notebook users, it could reduce the time to load an OS from storage devices like hard drives. The ferroelectric material could also retain data in case power is lost.
The research itself revolves around building ferroelectric transistors, which are capable of retaining data in any electric state, onto hybrid transistors.
The researchers took strontium titanate, a variant of the ferroelectric material used in smartcards, and deposited it on silicon, putting it in a state where it could retain information even when power is off. The new findings cut the intervening layers that made it difficult to put the material on silicon.
Typically when power is turned off, voltages disappear from transistors, which have to be recreated when power is turned on. To recreate them, the relevant information is loaded from nonvolatile storage mediums like hard drives, which takes time. The ferroelectric transistors retain magnetization when the electric field is turned off, allowing it to retain data.
The technology will load operating systems differently from existing memory technologies like DRAM and storage technologies like hard drives and solid-state drives, Schlom said. Ferroelectric transistors conceptually differ in the way data is loaded and retained, Schlom said.
Benefits of ferroelectric transistors were first realized in 1955 by scientists at Bell Labs, Schlom said. Though the recent findings are a major step ahead, additional research is needed to build an actual ferroelectric transistor to make instant-on computing a reality, Schlom said.
He couldn’t provide a timeline for when such transistors would be built.
The researchers also include scientists from the National Institute of Standards and Technology, Motorola and Intel. The research is funded by the National Science Foundation and the US government.
