Apple's Watch is designed to be both fashionable and functional.
First iPhone 5s and iPhone 5c Teardowns Show Touch ID Home Button, Nearly Identical Internal Layouts
Unsurprisingly, the internal layouts of the new devices are consistent with that seen in leaked part photos and generally in line with that of the iPhone 5. Battery capacities have increased from 5.45 Whr in the iPhone 5 to 5.92 Whr in the iPhone 5s and 5.73 Whr in the iPhone 5c. That iPhone 5s number is slightly different than what appeared in regulatory documents last week but is consistent with what we saw on a December 2012 prototype, albeit with a newer part number on the battery.
A direct comparison of the logic boards from the three devices also shows how Apple has slightly narrowed the boards on the new devices compared to the iPhone 5, making room for a slightly larger battery.
Other tidbits discovered during the teardown include a metal clip holding in the new cable providing a connection for the Touch ID sensor in the home button, as well as a new coating on the power button believed to be designed to increase durability.
More information from the new iPhones is undoubtedly forthcoming, with the teardown experts at iFixit also drawing upon their own extensive experience to delve into the details on the various components.
