The iPhone 12 and 12 Pro are already out and about in certain time zones, cue the first reviews, camera or battery tests, and, yes, teardowns. 

You now don't have to hope that iFixit will be able to fly someone into locked-down Australia to get your iPhone 12 and 12 Pro disassembly on tape before the US wakes up, as the vast confines of the Chinese tech blogosphere already did it.

Now that the iPhone 12 innards are displayed for all to see, the sheer amount of work that went into designing the new MagSafe charging coil/accessory magnet is clearly visible, and we also get to learn the exact battery size that Apple has put inside, as well as the 5G modem type. 

Here's what we find inside the iPhone 12/Pro after the first teardown:

  • 2815mAh battery
  • Qualcomm X55 5G modem
  • MagSafe charging coil
  • Thinner 6.1" OLED display panel
  • Smaller Taptic Engine vibration motor

Yesterday, we found the iPhone 12, mini, Pro and Max battery capacities listed in an Apple database, and the disassembly now confirms our calculations that the pack's listed 10.78Wh translate as exactly 2815mAh at the 3.83V voltage threshold. 

That's a bit less than 10% decrease in capacity from the iPhone 11, yet Apple cites absolutely the same battery life for the iPhone 12 based on decreased overall power consumption from the newer components.
