Leaked Photo Of iPhone 5/iPhone 4S Logic Board With A5 Chip, Battery?

iPhone 5

PhoneArena has published a photo, which they claim is the logic board for iPhone 4S or iPhone 5. The photo first appeared on the microblogging site Weibo.

The photo clearly reveals Apple’s A5 chip, which currently powers iPad 2 and widely expected to power iPhone 5.

We had seen leaked photos of iPhone 4S/iPhone 5 logic board couple of weeks back, but at that time the the chip was missing. As you can see below, the photo also reveals the battery pack. Interestingly, the specifications of the battery in this photo seems to be little different from the one we have see earlier. MacRumors explains:

Earlier photos had shown the battery offering 3.7 V and 5.3 Whr, for a charge capacity of about 1430 mAh. For comparison, the current iPhone 4 battery checks in at 3.7 V and 5.25 Whr, offering 1420 mAh of charge. 

This new photo appears to have the charge of 1430 mAh stamped directly on it, but curiously seems to list the voltage at 4.2 V. It is unclear exactly why the battery seems to be reporting a different voltage, and thus a different energy close to 6 Whr to reach the same 1430 mAh charge seen in earlier photos of the same part.

We just hope this means that Apple’s new iPhone will come with improved battery life.

So far, we’ve heard conflicting reports about next generation iPhone’s form factor. According to some reports, next generation iPhone will be completely redesigned and will look more like iPod Touch 4G rather than iPhone 4. While, some reports claim that fifth generation iPhone will come with improved specifications such as faster processor, 8-megapixel camera etc. just like iPhone 3G and iPhone 3GS, but won’t feature an all-new design and will look like iPhone 4.

In fact, according to some reports, Apple will launch two new iPhone models – a cheaper 8GB entry-level iPhone model, which looks like iPhone 4 that has been unofficially dubbed iPhone 4S and a redesigned iPhone 5.

While we expect iPhone 5 to be powered by Apple’s faster dual-core A5 chip, it would come as a surprise if the cheaper iPhone 4S model will also be powered by the A5 chip.

Purported iPhone 5 / iPhone 4S Logic Board Reveals Faster Dual-Core A5 Processor?

August 26th, 2011 08:57 admin View Comments

After the purported iPhone 4S casing leak, images of the next generation iPhone’s logic board have hit the web.

There isn’t any sort of surety over whether the board belongs to the iPhone 5 or the low cost iPhone 4S, but it is definitely different from the logic board on the iPhone 4.

The GSM iPhone 4 and CDMA iPhone 4 themselves have different logic board designs, and the leaked part bears some resemblance to the latter version. The inclusion of a SIM card slot on the leaked logic board and its similarity to the CDMA logic board could possibly mean a dual-mode CDMA-GSM iPhone that supports both GSM and CDMA networks as some rumors have suggested.

Another big takeaway from the leaked images is the possibility of the next iPhone running on Apple’s faster A5 system-on-chip, which currently powers iPad 2. This of course isn’t really surprising, the A4 chip first made its appearance on the iPad and later made its way to the iPhone 4.

The evidence that points to the A5 chip is the rectangular area meant for housing the processor found on the leaked logic board as compared to iPhone 4′s square enclosure. The A5, as revealed in iPad 2 teardowns is rectangular in shape while the A4 is square.

Ever since Apple launched iPad 2 with the A5 processor, it has been widely speculated that iPhone 5 will sport an A5 chip, in fact, according to one of the rumors, iPhone 5 has been delayed due to A5 chip overheating issue.

The dual-core 1GHz A5 system-on-chip is twice as fast as A4 and offers 9 times faster graphics, which means everything works better – apps load faster, smoother multitasking, improved gaming experience, better FaceTime video calls etc.

We can’t wait to get our hands on the next generation iPhone powered by the A5 chip. What about you?

Bringing Old Arcade Machines Into the Internet Age

An anonymous reader writes “To celebrate the opening of their hackerspace, Sprite_tm of SpritesMods hacked an old 1943 arcade machine to record its high scores, as well as post them on Twitter, via a newly added TCP/IP stack. The bus-tapping module he added to the machine lets him read the full contents of the Z80 logic board’s memory, allowing him to store high scores for posterity as well as add an Ethernet interface. The device should work on any Z80-based machine, which makes it easy to add these same capabilities to any old arcade cabinet.”

A Look At Next iPhone’s Internals; No User Removable Battery

April 21st, 2010 04:20 admin View Comments

iPhone 4G internal components

A lot of interesting details have emerged over the past few days with respect to what could be Apple's new iPhone. 

Following up on their coverage, Jason Chen from Gizmodo has now published fresh pictures that give us a better understanding of what lies beneath the casing of the new iPhone.

Here is a look at some interesting details:

Battery: The battery of iPhone 4G is not user replaceable just like the current and older iPhone models. The iPhone casing is secured by a couple of screws, which will prevent users from removing the battery. The battery in the new iPhone could be considerably larger than what was available on iPhone 3GS and occupies over 50% of the space inside the phone.

Logic Board: Compensating for the battery's larger size is the new logic board in iPhone 4G that is much smaller than the one on iPhone 3GS. The new logic board is enclosed within a metal casing and is roughly one-third of its original size. Chen notes that most of the important components, including the iPhone processor, reside inside this metal casing. As a result, not much information is available as yet on these components.

This apart, Chen also observes that the new iPhone could weigh close to 3 grams more than the older version despite it being thinner than iPhone 3GS. This is primarily because of the larger battery in iPhone 4G. While it is possible that Apple works over these minor chinks in design before the official launch. Chen seems to disagree, he says that the intricately assembled components inside the iPhone 4G prototype gives little space for components to be added or removed from the prototype design.

While the images above give us a sneak peek into the minutest of details regarding the upcoming iPhone model, critical information about the new iPhone's processing power, RAM and storage options still remain unanswered. 

With the official launch expected to happen only in the latter half of June, we cannot wait to get our hands on the next generation iPhone. How about you? Tell us in the comments.

MacBook Mod Gives Base Station Chassis New Purpose

December 1st, 2009 12:30 admin View Comments

odysseus31173 writes “A little over a year ago, I began developing for the iPhone and needed a working mac (not a Hackintosh), so I decided to purchase a MacBook logic board to save on cost. I modded a Linksys case to accept the logic board (along with all of the other hardware) and made it function again. The Mac currently runs Leopard and has a working iSight and mic along with fully functional WiFi and bluetooth. The RAM is the standard 1 gig, but the hard drive has been upgraded to 160 gigs. The iSight/mic holes in the front panel are hard to see and this could be used as a nanny cam of sorts.”
