Each year, Apple releases a new generation of iPhone, which will arouse worldwide cheers. This year's iPhone 6s is no exception. Mainland China is fortunate enough to once again become the starting area. Today is just the day of delivery. Apple fans should receive the first iPhone 6s/6s plus. Today we will take a look at the internal changes of the iPhone 6s. How does the new 3D Touch and Taptic Engine feedback motors fit into this small body? Please follow our steps to continue to look at the iPhone 6s. Disassemble details. (Source: ifixit, translation: 91 demolition)
From the outside, the iPhone 6s and the iPhone 6 last year can be said to be exactly the same, but the configuration has been upgraded a lot to see:
Apple A9 processor and M9 assist processor
Available with 16, 64 or 128 GB ROM
4.7 inch 1334 x 750 pixel (326 PPI) retina screen, 3D Touch
The front camera is 500W, and the rear camera has a 1.22 micron but pixel-sized 1200W iSight camera that supports 4K video recording.
Harder 7000 Series Aluminum Alloy Housing, Lon-X Glass
802.11a/b/g/n/ac Wi-F, Multiple Input Multiple Output, Bluetooth 4.2, NFC, 23-band LTE
New Taptic Engine Feedback Motor
Compared with the iPhone 6 (left), there are subtle differences. The back panel iPhone logo has more "S" letters, 11% more weight, and a 0.2mm increase in thickness, which is due to the addition of 3D Touch.
Before dismantling, come to X-ray perspective.
Use a screwdriver to remove the two screws on the bottom of the iPhone 6s.
Use the suction cup tool to separate the front and rear panels.
Compared with the iPhone 6 (left), you can see that the iPhone 6s has a slightly smaller battery, and a new Taptic Engine feedback motor is added underneath the battery. The number of cables connecting the screen and the motherboard is changed from four to three.
Like previous iPhones, the battery cable is still covered by a metal shield, and the metal shield can be removed by unscrewing the screws.
Remove the cable with a crowbar.
The screen cable is also covered by a metal shield. Remove the shield and use a crowbar to remove the cable.
Although 3D touch was added, the screen of the iPhone 6s was reduced from four to three. The glue of the new iPhone is really strong, and we see a rubber strip on the edge of the screen.
The weight of the monitor is as high as 60 grams, which is the main reason for the increased weight of the iPhone 6s. We compare the screen with the iPhone 6 (left). The display components of the two are very similar except that the style of the metal shield differs slightly from the design of the cable.
Remove the shield bracket at the top of the screen. The speakers and front camera are below.
Although the front camera was upgraded from 120W to 500W, the appearance is still very similar.
Remove the speaker. Then we can dismantle the screen. Here we are about to unveil the mystery of 3D Touch.
Remove the screen's metal shield.
There is a chip on the back of the screen that we have not seen before. We think this is the control chip of 3D Touch. The model number is 343S00014. The naming method is similar to Apple's other chips, but the supplier of this chip is not yet known.
Remove the Home button.
In contrast to previous generations, the new generation of Touch ID (right) Apple claims to be faster and more accurate, but we did not find much difference in the appearance of the new Home button.
By observing the X-ray perspective, we can see Apple's latest Taptic Engine feedback motor.
Continue to dismantle, this is the Taptic Engine feedback motor that appears on the iPhone for the first time.
The Taptic Engine feedback motor is similar to the ForceTouch trackpad on the Macbook. The Taptic Engine feedback motor can provide you with a real press feedback experience.
Use tweezers to gently peel open the battery cable.
Remove the adhesive from the bottom of the battery.
Take out the battery.
Compared with the previous generation, the battery capacity was reduced by 95mAh, and the volume was reduced. This is also a compromise to make room for the Taptic Engine feedback motor.
This is Apple's new 1200W iSight rear camera.
The new camera has dramatically increased the number of pixels, which is the first time that Apple has increased the number of pixels after the iPhone 4S uses the 800w camera.
Remove the hex screw that secures the antenna cable from the red circle, and the three screws that secure the antenna element.
Use tweezers to gently clamp the antenna element.
It was found that the antenna element used the same model as the previous generation.
Take out the motherboard.
Take a look at what chips are on the motherboard:
Red: Apple A9 APL0898 SoC with Samsung LPDDR4 RAM
Orange: Qualcomm MDM9635M LTE Cat.6 chip
Yellow: Should be Mason MP67B six-axis gyroscope and acceleration sensor integrated chip
Green: Bosch 3P7 LA triaxial acceleration sensor
Light blue: superior TQF6405 power amplifier
Dark blue: Sijia SKY77812 power amplifier
Purple: Avago ACPM-8030 power amplifier
In addition there is a chip called 57A6CVI.
It is rumored that the area of ​​the A9 chip is 15% lower than that of the A8, but according to our measurement, the appearance size of the A9 is 14.5×15 mm, while the appearance size of the A8 is 13.5×14.5 mm, but we cannot determine the size of the chip area. Apple may have Integrate other chips in A9.
Chips on the back of the motherboard are more:
Red: Toshiba THGBX5G7D2KLFXG 16 GB 19nm NAND Flash
Orange: Universal 339S00043 Wi-Fi
Yellow: NXP NFC 66V10
Green: Apple Dialog 338S00120 PMIC Power Management IC
Light Blue: Apple Cirrus Logic 338S00105 Audio IC
Deep Blue: Qualcomm PMD9635 PMIC Power Management IC
Purple: Sijia SKY77357 Power Amplifier
There are more chips:
Red: Murata 240 front-end module
Orange: RF Micro Devices RF5150 Antenna Switch
Yellow: NXP 1610A3
Green: Apple Cirrus Logic 338S1285 Audio IC
Light blue: Texas Instruments 65730 AOP NFC booster IC
Dark blue: Qualcomm WTR 3925 wireless transceiver chip
Remove the last part in the backshell: speakers.
Take a closer look at the speakers. The 6S speakers are similar to those on the iPhone 6, but they are slightly different and may have been modified to match the Taptic Engine feedback motors.
It is now known to be highly integrated by removing small boards and cables.
It should be noted that the iPhone 6s has two microphones at the bottom.
The opposite side of the small plate has a large area of ​​contact.
Remove the screw that holds the power button.
Use the tweezers to slowly move in and find that there are fewer spacers than the previous generation.
After our dismantling is complete, we will complete a family portrait. iFixit scored 7 points for the maintenance of the iPhone 6s (10 is the easiest to repair), this score is still good, the overall structure is similar to the previous generation, maintenance is not difficult.
