RepairLabs reviews that it has received an image of what is claimed to the interior of the back shell of the iPad 3, comparing the portion to the similar version found on the iPad 2. The iPad 3 edition demonstrates a few small changes compared to the iPad 2, with one of the most notable being an apparently narrower logic panel that could make room for an extended battery.
A. You can see here that the mounts for the logic panel are very unique, which indicates the logic board shape will be different permitting for . . .
B. Extra battery. The width of where the sense board rests on the iPad 2 looks much larger than that of the iPad 3. We have long heard that the iPad 3 was planning to provide extended battery life, and this back housing seems to support that.
The review also points out minor differences to the destinations where the iPad’s back camera and LCD screen mount to the back casing. While those changes obviously do not offer any evidence of enhancements for the components independently, they do recommend that Apple has at least improved their designs from the current iPad.
The image does not show the behind of the rear shell that would be noticeable on the constructed device, nor does it show an edge view that would allow for a depth comparison to the iPad 2. The images source does claim, however, that there is no apparent difference in width between the two rear shells.
Rumors did not agree on whether the iPad 3 will wider, slimmer, or the same width as the iPad 2, with some indicating that the final result depends on what type of display technology and backlight system Apple has resolved on for the device. The iPad 3 is said to be gaining a high-resolution “Retina” screen that could need new solutions for powering and lighting the display.
Other rumors have stated that the device will run utilize a quad-core processor on Apple’s next-generation “A6” system on a processor and that support for LTE mobile connectivity will be involved in some models.
