The iPhone 6s and iPhone 6s Plus are out, for at least some folks, and the techies over at iFixIt have already begun tearing the new handsets down to see whats under the hood. What have they found? Theyve discovered a slightly smaller battery in each device to accomodate the Taptic Engine module for the new 3D Touch technology. Lets take a closer look.
The first teardown iFixIt published was of the iPhone 6s. The video below shows the full process, andyou can click here if it doesnt load. Under a detailed inspection, we can see that the iPhone 6s is a hair larger than the iPhone 6, measuring 0.1 millimeter longer and 0.2 millimeter deeper than its predecessor. The iPhone 6s has also added a bit of weight, coming in at 143 grams compared to the previous generations 129 grams.
The Taptic Engine, according to the teardown experts, takes up a large portion of space below the battery, which they believe is why the power cell is slightly smaller. The battery in last years iPhone 6 had a capacity of 1,810 mAh, but the iPhone 6s sees just 1,715 mAh of charge.

Now, on to the iPhone 6s Plus. Once again, iFixIt reveals that the device is marginally larger than its predecessor, and weighs 20 grams more. Whats interesting is that the Taptic Engine in the iPhone 6s Plus is smaller than the one found in the iPhone 6s. This may be because Apple did not want to shave too much life from the battery in the larger handset. In fact, the difference is 165 mAh, a bit more than the change between the iPhone 6 battery and that of the iPhone 6s.

I love watching teardown videos, and Im sure many of you do, too. While we dont really recommend servicing your iPhone yourself, its good to see that Apple is only using the Pentalobe screws to secure the case; most of the internal fasteners are of the Phillips variety.
