It's been a few moments since it's been available for purchase, and as is customary, the iPhone 13 Pro has been torn down to its smallest parts, courtesy of iFixit.

Despite the new device being very similar to last year's iPhone 12 Pro on the outside, there have been some important changes inside, with Apple's engineers squeezing every possible millimetre of space to crammore tech into the phone.

The most important change is the battery. Apple claims the new iPhone 13 Pro has significantly better battery life than the iPhone 12 Pro, and it's visible in the physical size and the capacity of the battery. According to iFixit, the new, L-shaped battery in the iPhone 13 Pro has a 11.97 Wh capacity, compared to the 10.78 Wh battery in the iPhone 12 Pro.

Other things have been rearranged or combined to save space; for example, the Face ID's flood illuminator and dot projector have been merged into a single module, which is why Apple was able to make the notch on the iPhone 13 Pro some 20 percent narrower than on the iPhone 12 Pro.
