The first thing some people want to do with a brand new gadget is tear it open.
The good folks at iFixit and Chipworks did just that with the 4-inch iPhone SE, which went on sale today. They found the petite device looks like the iPhone 5S on the outside but packs the guts of the bigger iPhone 6S on the inside.
"Kinda like Taco Bell, same ingredients, new menu item," iFixit wrote in a teardown posted Thursday. "We're excited to see the perfect union of existing Apple tech in a new body."
As promised, the new phone has the same speedy A9 processor found in the iPhone 6S and 6S Plus. It also has the same RAM module, NFC chip and inertial sensor as the 6S, the teardowns show, as well as several of the same components -- like its Qualcomm modem and transceiver -- as the even earlier iPhone 6.
The display on the iPhone SE is nearly identical to the iPhone 5S. The tech gurus at iFixit were even able to plug a 5S display into the new phone and turn it on.
The iPhone SE also has a 1624 mAh battery, which is slightly more powerful than the iPhone 5S battery but less than the iPhone 6S. Apple says the SE battery offers up to 14 hours of talk time and will last for 10 days on standby.
