Ok, this is interesting.

Per Engadget, an updated model of the US$399 iPad 2 is floating around at retail, and it might improve battery life by as much as 16 percent.

The site is reporting that the lower-cost version of the iPad 2 introduced in March has quietly introduced a new 32nm A5 processor, and that could translate to improved battery life for budget-minded buyers.

The discovery was made by AnandTech, who did an extensive review on the upgraded model, which bears the “iPad2,4” model. Instead of the 45nm process used for the A5 processor used in the original iPad 2 last year, the newer US$399 model features “special A5 chips manufactured using Samsung’s 32nm chip-making process.”



In testing, the website discovered that the 32nm iPad2,4 model boasted improved battery life of 15.8 percent, including a video playback test that lasted 15.7 hours — far better than the original iPad 2 model at 13.3 hours and even the new iPad with its larger battery, which ran for a mere 11.15 hours.

Unforunately, there’s no way to tell which iPad 2 you’re buying until you’ve opened the box and checked the system information.

“This particular iPad 2,4 sample came from Best Buy, and several attempts to find one elsewhere came up short. All indications seem to point to the iPad 2,4 being relatively rare, which makes sense considering what’s inside it,” stated the AnandTech article.

So, it’s sort of a golden ticket that’s out there.

Rumor: Apple’s next-gen iPhone to be thinner, incorporate 4-inch screen, utilize metal backing and new dock connector

There’s got to be some element of truth here…

Per iLounge, Apple’s next-gen iPhone will be slightly taller to accommodate a 4-inch screen with a new aspect ratio, will feature a redesigned dock connector, and will also have a new metal panel on the back side, a new report claims.

The latest rumors about Apple’s sixth-generation iPhone stated that the new iPhone will be about 10 millimeters taller, giving it dimensions of 125 millimeters tall, 5.8 millimeters wide and 7.4 millimeters thick. That’s about 2 millimeters thinner than the current iPhone 4S, with essentially the same width as the current model.

Because the new iPhone will allegedly be the same width, that would mean that new applications would need to be designed to work with the handset. The taller screen would have more pixels at the top and bottom, giving it a different aspect ratio.

“According to our source, Apple will make one major change to the rear casing, adding a metal panel to the central back of the new iPhone,” the report said. “This panel will be flat, not curved, and metal, not ceramic.”

Author Jeremy Horwitz also added that the new iPhone is expected to be partially made from Gorilla Glass 2, which offers identical strength to the original Gorilla Glass with a thinner design. At just 0.8 millimeters thick, Gorilla Glass 2 can withstand 121 pounds of pressure.

Finally, the report also claimed that the next iPhone will have a new, smaller dock connector that will be “a little larger” than the bottom speaker and microphone ports on the existing iPhone 4S. The new port was described as “a pill shape,” and is believed to have just 16 pins, compared to the current 30-pin dock connector.

“It will be used in all upcoming devices, including an update to the iPod touch that’s expected this year, and will almost certainly feature a similarly updated screen and CPU,” the report said.

In March, iLounge reported that Apple was working on a new case for the iPad that would protect not only the front screen, as the current magnetic Smart Case does, but also the aluminum back panel of the device. The site credited a “repeatedly reliable source,” but such a case has not yet been released.

The rumors come on the heels of a new component claimed to be the SIM card tray for Apple’s next-generation iPhone. A home button also purported to be from a prototype Apple handset also appeared, but no components thus far have given any concrete indication that the next iPhone’s design will be a radical departure from the look of the iPhone 4 and iPhone 4S.

Still, there has been rampant speculation that Apple’s next iPhone will have a redesigned exterior. Rumors of unibody enclosures, larger screens and thinner form factors have all cropped up in recent months.

Early prototyping of the next iPhone is believed to be underway ahead of a launch anticipated this fall, one year after the debut of the iPhone 4S. In March it was said that Apple was reviewing potential components for the new iPhone.

Rumors surrounding the next iPhone have picked up steam in recent weeks, as one report said the handset will feature Qualcomm’s “MDM9615″ LTE 4G chip for high-speed wireless connectivity. Reports have also claimed that the next iPhone will adopt in-cell touch panel technology, which will allow Apple to make the next iPhone thinner by 0.44 millimeters, or fit in a larger battery.

This falls into the “If You’re Feeling Brave” category, but it could work nicely.

Per The Verge, MacBook Pro user Evan Rodgers took a CCTV battery, a third party MacBook car charger, and some soldering tools to create a do-it-yourself external MacBook battery.

Watch the video, see what you make of it and if you have the parts on hand, you can avoid a fairly costly trip to the Apple Store for a replacement MacBook Pro battery and add about two to three hours of on-the-fly usage:



Apple insists iPad 3 battery functions as designed, disputes charging analysis claims

Posted by:

Category: iPad, News

This may be someone’s fault, but Apple insists everything’s hunky dory.

Concerns about the iPad’s battery arose last week when an analysis was publicized claiming that the new iPad “prematurely” reports that it is fully charged by two hours. Dr. Raymond Soneira of DisplayMate claimed that the iPad actually finished its charging cycle some two hours after it reports a full charge.

That’s by design, Apple’s Michael Tchao said to All Things D on Tuesday. All iOS devices, including the new iPad, will display that they are 100 percent charged just before the device reaches a fully charged state. The device will then continue charging, then discharge a bit, and recharge once again — a cycle that will continue until the device is unplugged.

“That circuitry is designed so you can keep your device plugged in as long as you would like,” Tchao said. “it’s a great feature that’s always been in iOS.”

Apple’s battery percentage display is simplified so that users are not confused by the constant cycle of charging and discharging while a device is plugged in. But Apple’s approach allows all of its iOS devices to maximize their potential battery life.

Apple has boasted that the new iPad offers the same 10-hour battery life as its predecessor, even with the inclusion of a new quad-core graphics processor and 3.1-million pixel Retina Display. The new high-speed 4G LTE model also offers 9 hours of battery life when using a wireless network.

In particular, the Verizon model of the new 4G LTE iPad can serve as a mobile hotspot for more than 24 hours when sharing a high-speed data connection with external devices over Wi-Fi. That’s upwards of five times longer than most standalone 4G LTE hotspots.

Third-generation iPad may be displaying inaccurate battery readings, researcher finds

A firmware update is never a bad thing.

Per AppleInsider, findings that have surfaced from a follow-up test by DisplayMate President Dr. Raymond Soneira, who conducted an in-depth analysis of the new iPad’s Retina Display earlier this week, and claims that a mathematical charge rate model may be the cause of false on-screen battery indicator readings reported on the iPad 3.

Soneira’s findings have not been corroborated and thus may not reflect all third-generation iPads, though it seems that the problem is not hardware related and instead has to do with the device’s programmed charge rate.

In his investigation, Soneira found that the iPad continued to draw 10 watts of electricity for two hours after indicating 100% charge, then began to reduce power for an additional ten minutes until a precipitous decline in power draw signaled the termination of the charging cycle.

Soneira offers this explanation:
“The charge indicator on all mobile devices is based on a mathematical model of the charge rates, discharge rates, and recent discharge history of the battery. It uses this information to estimate how much running time is left. It’s actually rather difficult to do because most batteries degrade slowly as they discharge and then tend to surprise with a precipitous decline near the end.”

He goes on to say that there may be a fault in the battery charge mathematical model in the new iPad as the indicator should not read 100% until it’s power draw switches from 10 watts to a trickle charge of about 1 watt.

It is unclear whether the iPad’s battery level indicator shows an inaccurate level throughout the entire charging process or if the issue is limited to the final stages directly before the power management chip initiates a trickle charge.

While Apple boasts that in spite of its power hungry components like the high-resolution Retina Display and A5X processor, the third-generation iPad’s battery life is similar to that of the iPad 2. These claims are no doubt based on a fully charged unit, and the newly-discovered indicator issue could confuse some customers into thinking their device is not performing up to advertised standards.

Colorado woman’s iPhone 4 allegedly combusts while charging, exact causes unknown

On the down side, an Apple iPhone 4 in Colorado apparently caught fire.

Still…SOMETHING had to catch fire.

Per Mashable, a Colorado woman alleges that her iPhone 4 caught fire while charging overnight and wants Apple to warn customers of the device’s possible combustion issues.

The woman, who spoke under the condition of anonymity, said she released her story in order to spread public awareness over the reported issue, claiming that Apple has been reticent to acknowledge the alleged incident.

The unnamed source claims that she awoke in the early morning during a recent trip to the east coast to find her year-old white iPhone 4 making “sizzling” and “popping” noises. After an unspecified amount of time there was “not quite an explosion, but an immense crackling,” and smoke plumed from the device creating “an awful, putrid smell, almost like you were ingesting plastic of some kind.”

Inspection of the provided pictures yields no clues as to which components were heated to the point of creating smoke, though it a bulging battery is clearly seen to have expanded enough to force apart the iPhone’s casing.

According to the report, the iPhone was connected via an Apple-branded charger to a power outlet that was later inspected and found to be working normally.

The woman goes on to say that when she asked Apple to be upgraded to a replacement iPhone 4S, the company furnished her with another iPhone 4.

“I would have liked to have seen them say they understand this might not be something that affects everyone,” the Colorado woman said. “But, because it happened here, [they should] put up a precautionary statement to make people aware that if their battery becomes too hot to be wary.”

The alleged incident is reportedly the first of its kind in the U.S., though there has been at least one similar instance in Australia involving the iPhone 4.

This is not the first time Apple has seen problems with overheating batteries as it extended a replacement program for its first-generation iPod nano in 2011 due to a defect that caused the device’s battery to overheat. The Cupertino, Calif., company first acknowledged the problem in a 2008 press release that stemmed from an investigation by the Japanese government.

There have been no reports of severe overheating issues with the iPhone 4S or any other products in Apple’s current lineup.

iPad 3 RAM doubled to 1GB, battery life to remain about the same

The third-generation iPad may look fairly identical to its predecessor, but it’s what’s inside that counts.

Though the new A5X chip in Apple’s third-generation iPad features the same dual-core CPU found in its predecessor, the system-on-a-chip is still believed to double the onboard RAM to 1 gigabyte.

Although Apple has never announced the amount of RAM built into any iPad or iPhone, preferring to focus less on technical specifications and more on the abilities of a devicea source who spoke with The Verge said the new A5X processor found in the latest iPad will, in fact, feature a gigabyte of RAM.

This amount doubles the 512MB of RAM found on the iPad 2 and says something about the iPad 3′s new battery, as RAM limitations in previous chips were said to be driven by battery life concerns. Last October, Microsoft explained that RAM is constantly consuming power, so the more memory that is included with a system, the less battery life it gets.

Reports first surfaced ahead of Apple’s iPad unveiling that Apple would increase the RAM in its custom processor. The information was derived from alleged iPad debug photos that leaked last month.

The new A5X processor features a dual-core CPU, the same as the A5. But its performance has been boosted by a new quad-core graphics processor that Apple says is twice as fast as the Nvidia Tegra 3 while offering four times the performance.

If you’re going to snag an iPad 3, it never hurts to have it under warranty.

Per MacNN, in tandem with announcing a third-generation iPad, Apple has also brought its AppleCare+ warranty option to the tablet. By default an iPad is only given a limited one-year warranty, with 90 days of free support. Paying US$99 extends coverage up to two years, and allows for two incidents of accidental damage, although in each instance a US$49 service fee still applies.

The plan covers not just an iPad but its battery, power adapter, and USB cable, as well as any AirPort or Time Capsule device bought during coverage or two years before. AppleCare+ must, however, be applied no later than 30 days after buying an iPad. The warranty package was initially offered only to iPhone 4S buyers.
