Apple's latest flagship smartphone is due in stores tomorrow morning, and naturally, iFixit has put one of the shipping units under a screwdriver before launch. We can't say we're surprised: these folks have sort of made a habit of it. The iPhone 5s teardown is currently marked as "in progress," but the disassembly artists have already found the device slightly more difficult to take apart than its predecessor, due to the Touch ID sensor's short connector cable. The new iPhone's 1560mAh battery (a modest upgrade from the iPhone 5's 1440mAh) is also held down by a ton of glue. The team expresses some concerns over the CMOS Touch ID sensor's sapphire crystal cover, cautioning that its accuracy could degrade over time if it isn't adequately protected. At the time of this writing, the 5s is still coming apart, and iFixit is adding more detail by the minute. Hop on over to the source link below to see the tear down in progress, or check back here later for an update with the company's final word.
