iFixit is currently performing a teardown of the new iPhone 4S.
Highlights: ● an extra .05 WHrs in the battery over the iPhone 4! ● Qualcomm MDM6610 chipset
iPhone 4S Repairability Score: 6 out of 10 (10 is easiest to repair). Very little has changed from the iPhone 4 in terms of repairability. ● The iPhone 4S is still held together primarily with screws and limited adhesive. ● The rear panel and battery are both easy to remove and replace (provided you have the right kit and/or correct screwdriver). ● Apple is again using Pentalobe screws to secure the rear panel and keep people out ● The LCD and glass -- a carryover from the previous generation -- are fused together, making cracked glass repair more costly. ● Lots of smaller components are soldered to one ribbon cable, increasing the cost of repairing just one component.
