We’re finding this to be a trend amongst the smaller multiple-camera devices, and it makes sense-the info needs to go to the same place to be processed.
All three cameras are connected together via one ribbon cable. We had to call forth the use of a heat gun and a plastic opening tool in order to gain access to the upper display screws. Whereas older versions of the DS had four rubber screw covers on the front display bezel, Nintendo opted for a sleeker approach for their new system by adhering a front panel to the bezel to hide the screws. The digitizer on the bottom display is much thicker than those found on most cellphones, most likely due to the fact that the touch display is used with a stylus, rather than a fingertip. 
The IR controller IC is manufactured by NXP and has the markings: S750 0803 TSD031C Nobody is really certain what the infrared port on the 3DS will do just yet, but we’re thinking it’s for some 3DS to 3DS line-of-sight communication.We found an interesting little feature of the 3DS by accident while blowing away some dust with canned air: external mics on the 3DS pick up the characteristic noise of wind blowing by the device and spin the live icons in the background of each menu as if they were in a tornado.

According to them, a full charge takes 3.5 hours.
With the short battery life in mind, Nintendo ships the 3DS with a charging cradle for convenient charging. The battery life is most likely diminished by the reported faster processor, dual LCD elements in the top display (to control the parallax effect), and more hardware intensive programs. Even when playing original DS games, the 3DS lasts only 5-8 hours on a single charge. The 3.7V, 1300mAh, 5Wh Li-Ion battery provides a measly 3-5 hours of battery life. This makes for a cleaner look, but also means that replacing the battery will take a little longer. Unlike previous DS consoles, the entire back cover of the 3DS comes off as one piece rather than having a small door to access the battery. To him the screen looked different, but not 3D. The 3D view *should* work for most people, but one iFixit employee (out of about 10 that tried it) had trouble viewing it. That device used slightly different means to achieve a similar 3D effect. Nintendo is no stranger to 3D gaming, considering its past experience with the ridiculously cool and underrated Virtual Boy. When it is viewed from the recommended distance, the image appears to be 3D. A layer in the top LCD responds to adjustments in the 3D slider and changes the image slightly between each of the viewer’s eyes. The 3DS’ top display produces 3D images through the use of parallax. We decided that threading the upper display and camera cables through the tiny hinge tube is something that Nintendo undoubtedly accomplishes with robotic machinery, and should not be attempted by human souls unless they’re willing to potentially destroy their device. Even with our super-careful hands, we still managed to break a couple of the ribbon cables. To continue the disassembly, we had to separate the hinges and do a bunch of cringe-inducing threading of ribbon cables through the 3DS’ hollow hinges. But then we tried to access and remove the top display, and the disassembly went awry from there. Everything was coming apart just hunky dory: we removed all the Phillips screws and easily disconnected all the components on the bottom half. The Nintendo 3DS received a 5 out of 10 repairability score, mainly for the extreme difficulty in accessing the top half of the unit. Exactly how much did that 3D screen change things internally, we wondered… And then we snapped out of it, got a Phillips #00 screwdriver, and wondered no more. We wanted to give our 3D friend a thorough shakedown-it seemed fitting, given that its older brethren graced our teardown pages in the past. 
Hot off a plane from Japan comes no other than our very own Nintendo 3DS unit.
