from the if-it's-broke,-fix-it dept.
iFixit has posted a detailed teardown of the new iPhone 5. While the casing still uses Apple's proprietary pentalobe fasteners, the good news is that Apple has made the screen much easier to remove. Once the fasteners have been removed, the screen will lift out easily through the use of a suction cup. The screens are by far the most common parts of iPhones to break, and this change turns a complicated 38-step procedure that takes about 45 minutes at minimum into a quick, 5-10 minute job. The teardown also shows the iPhone 5 battery to be very similar to the iPhone 4S's, suggesting that the improvements to battery life come from other hardware and software changes. We get a look at the new A6 processor running the phone, which is a custom design based on ARMv7. iFixit also looks at the Lightning connector assembly; unfortunately, it includes the loudspeaker, bottom microphone, Wi-Fi antenna, and headphone jack as well, so fixing any one of those parts individually will be difficult. Whatever you think of Apple's decision to move to Lightning instead of micro-USB, it seems their switch away from the 30-pin connecter was necessitated by size constraints.
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
