There is actually a major change about the iPhone 15 Pro that is "invisible", which is the redesign of its internal frame structure. In the latest video, the YouTube channel PBKreviews disassembled the Apple iPhone 15 Pro model. Today, PHONEFIX will lead you to explore the internal structure of iPhone 15 Pro.
Design structure
For years, smartphones have either opened from the front or the back. Apple finally solved this problem with the regular iPhone 14 in 2022, enabling the phone to open from the front and back. This huge upgrade allowed us to improve the iPhone's repairability score over previous models.
Apple has redesigned the middle frame structure of the iPhone 15 Pro to make it easier to replace the back glass. If you need to replace the back glass, you only need to heat the back plate, then pry open the glass on the back cover, and disconnect the flexible circuit board from the back of the circuit board. Cables, just replace it with new back glass.
USB-C
Apple has always been widely criticized for planning its own product design route, but convincing Apple to change its direction required tremendous pressure. It was not until the European Parliament mandated a unified interface that it was achieved.
In addition to the obvious compatibility benefits, the new USB-C port can deliver 4.5 watts of power to external devices. Compared with the previous Lightning mobile phone interface that could only output 0.3 watts, this is a 15-fold upgrade.
The A17 system-on-chip (SoC) adds a USB 3 controller, enabling USB 3.2 Gen 2 10 Gbps transfer efficiency. Because non-iPhone 15 Pro models inherit the older A16 Bionic, they only support USB 2 and are limited to the same transfer speeds as previous Lightning-powered devices.
Cell phone battery
The battery capacity of the iPhone 15 Pro is 3274 mAh, which is better than the 3200mA of the previous iPhone 14 Pro, an increase of about 2.3%. According to Apple’s official battery life data, the battery life of the two is the same, and the video playback time can be up to 23 seconds. Hour. Therefore, the actual experience of the increase in battery capacity is probably not strong.
Overall, battery capacity growth is weak. This is certainly not good news, as the A17 Pro is very power-hungry. There have been previous reports that the phone will get hot and continue to heat up, and the battery life will be shortened accordingly.
Brand new titanium case
The largest amount of metal in an iPhone is in the frame, so Apple turned to advanced metallurgy to save weight and gain some marketing points.
An interesting theory about weight reduction is that by taking the weight off the perimeter of the phone, it will feel easier to move around. The technical term for this is moment of inertia, or the force required to rotate the phone about its axis. The technical term for this is moment of inertia, which is the force required to rotate the phone on its axis. With less edge weight, the phone feels more nimble in your hand—like tucking its legs in when rotating. Compared with the actual weight reduction of 9%, the iPhone 15 Pro series will bring a greater "feeling" of being lighter.
Electronic components
Through the teardown, we can confirm that Apple is using Qualcomm's high-end Snapdragon X70 modem. According to Qualcomm, it is powered by artificial intelligence for beam management and antenna tuning.
The Apple A17 Pro six-core application processor comes with a six-core GPU that may sit under SK Hynix DDR5 memory.
Camera
The big camera upgrade this year is a "prism" periscope lens that boosts the iPhone's optical zoom from 2x to 5x. The Samsung Galaxy S23 Ultra technically beats this with 10x zoom, but the way Apple engineers achieved it is particularly interesting.
A physical challenge smartphone camera designers have struggled with is the thickness of the phone's lens system, and using a periscope allows the sensor to be slightly offset from the lens, thus reducing the thickness of the lens module.
