iFixit did so as well in the new teardown, starting off by trying to get into the back of the S9+ to look at its rear-facing camera components. After applying heat, the iFixit team got into the smartphone and found its dual-aperture camera system, which the team described as one of the only significant hardware changes this year.
iFixit explained that the S9+ has a rear-facing camera that automatically adjusts its aperture for low light, and at f/1.5 it has the widest aperture of any phone. For normal photos, Samsung's new device still has a "more standard" f/2.4 aperture. In comparison, the iPhone X's dual 12 MP rear cameras include f/1.8 and f/2.4 apertures.
Standard camera lenses use at least five aperture blades to keep the aperture roughly circular throughout many f-stop adjustments. This Galaxy's aperture has just two rotating, ring-like blades for its single adjustment.After some trouble dislodging the rear fingerprint sensor, iFixit moved to focus on the battery within the S9+ and discovered a 3.85V, 3,500 mAh battery. As the iFixit team pointed out, the battery in the S9+ shares the same specs as those found in the S8+ last year, and in the Note7 in 2016. The iPhone X's battery teardown uncovered a 3.81V, 2,716 mAh battery in Apple's smartphone.
Eventually, the team got underneath the S9+ display and compared its front-facing camera components side-by-side with the iPhone X. iFixit noted that Samsung's AR Emoji are "lower-tech" compared to Apple's Animoji, mainly because the S9+ front-facing hardware -- composed of an iris scanner, camera, IR emitter, and proximity sensor -- are "pretty much exactly" the same as the tech from the Galaxy S8+.
Because of this, iFixit pointed out that it might have been a bit too soon for Samsung to debut its own animated emoji characters "without a hardware update to bring it up to speed." To further explain the distance between the technologies, the teardown team described Apple's Animoji as having Kinect-level tracking, while Samsung's emoji are more akin to Snapchat filters.
iFixit gave the Samsung Galaxy S9+ a repairability score of 4 out of 10, explaining that there are a few modular components while noting the chance for breakage if attempting to repair the display and rear glass panel. The iPhone X fared slightly better in its teardown with a 6 out of 10 score. To read more about the Galaxy S9+ and its teardown, visit iFixit's website.
