iPhone 4S teardown reveals few changes – slightly larger battery, new vibration motor

Thu, Oct 13, 2011


iFixit got their hands on an iPhone 4S and wasted no time in tearing Apple’s next-gen smartphone apart. There’s really all not that much new from the iPhone 4 but here are a few notes of interest.

Though checking in at 1GHz, Apple’s A5 processor is underclocked to help conserve battery life. Further, the worldmode Qualcomm chip which enables one device to work on both CDMA and GSM networks is a Qualcomm MDM6610. Further, and as had been reported earlier, iFixit confirms that the iPhone 4S only comes with 512MB of RAM.

Battery wise, the 4S provides the most amount of talk time out of any iPhone Apple has ever released – 8 hours to be exact. This is thanks to a slightly larger battery with extra .05 WHrs.

One final tidbit, Apple updated the vibration motor i the iPhone 4S to the one used in the CDMA iPhone 4 on Verizon meaning that it opted for a linear oscillating vibrator which iFixit claims isĀ “quieter, softer, and all-around less annoying than its counter-weighted predecessor.”
