iFixit has reportedly tore down the iPhone 4s to reveal its insides which are rather interesting! A day before iPhone 4S’s official launch in the stores, iFixit managed to obtain the device and was able to strip it to its parts!
iFixit reports that the device differs little from the CDMA-compatible iPhone released earlier this year, but there are still a few tweaks and changes on the inside. The battery in the iPhone 4S has 0.05 watt-hours of extra juice inside compared to the iPhone 4. This improvement of the battery allowed for the device’s improved 3G talk time. The device also had an updated Qualcomm MDM6610 dual-mode baseband for the CDMA. iPhone 4 used an MDM6600 and the GSM model which used an earlier Infineon chip.
The iPhone 4S also uses the improved vibrator motor found in the CDMA iPhone. The touchscreen panel uses the same connecting points as the older GSM iPhone 4 instead of those of the newer CDMA model. The A5 package contains two 2Gb dies—in other words, 512MB. Also the markings on Apple’s A5 processor also confirm a detail that had been in question—namely, the amount of RAM included in the package. While the iPad 2 contained 512MB—the same as the iPhone 4—some rumors suggested an A5-equipped next-gen iPhone would have 1GB of RAM.
However looks like the RAM was left untouched at 512MB. iFixit awards the device a 6 out of 10 score for repairability, the same as previous iPhone 4 models.
