"Last year's new iPhone underwent a complete revision, while this year's iPhone maintained a similar appearance to last year, which is like we are experiencing a tick / tock update cycle; The following is what we know:
A12 bionic processor of six core new generation neural network engine
458ppi ultra retina HD display with 5.8 inch (resolution 2436x1125) and 6.5 inch (resolution 2688x1242) with true tone, wide color gamut and 3D touch
Rear mounted dual 12MP cameras (wide-angle + telephoto combination), with aperture of ƒ/ 1.8 and ƒ/ 2.4, equipped with OIS optical anti shake, 7mp original depth front camera, ƒ/ 2.2 aperture, support 1080p video recording and face ID function
64GB storage capacity (256gb or 512gb optional)
Support Gigabit LTE network (non 5g network) and 802.11a/b/g/n/ac wi ‑ fi, MIMO, Bluetooth 5.0 and NFC
Stronger dustproof and waterproof ability, reaching IP68 level
We won't judge the new product only by the appearance of gorilla glass, but on the surface, it hasn't changed much from the previous generation of iPhone X
···Like the new gold and this enlarged size
Fortunately, creative electron can let us know where there are traps inside before disassembly（ High tech equipment from creative electron still uses x-rays) we can preview the internal structure in advance
Here are all our x product lines
We note that compared with the previous generation, this generation of products has an additional antenna strip on the left side of the microphone, which may be related to Gigabit LTE, but it really seems to make a difference
Our disassembly engineers work with both knives and abide by the disassembly specifications at the same time
Not shown: the second right hand of our disassembly engineer
Apple may be thinking about how to change the naming of products. Fortunately, it doesn't want to change the disassembly of products
Our iiopener is softening the adhesive of two mobile phones and removing the screen with suction cups and crowbars
Although we are worried that Apple may use more adhesives to make the product reach the waterproof grade of IP68, at present, we do not use more adhesives than the previous generation of IP67 products
In the face of dismantling two equipment at the same time, our manpower is slightly insufficient. Therefore, we invited famous local muscle players in Australia to help us disassemble
Facts have proved that the lack of manpower can indeed slow down the disassembly speed, but under our disassembly tutorial, even kangaroos can disassemble
With the removal of the screen, we see some differences between XS and XS max
The taptic engine in XS Max has been redesigned - larger mobile phone, stronger vibration?
At the same time, XS Max has a larger logic board, and the display controller has been moved to the lower part
The XS battery looks more strange and is a newer product. In contrast, the XS Max battery is the same as the previous design
In order to find measures to improve the waterproof level, we turned to the largest opening on the fuselage - SIM card slot
Although the shape is slightly different, the gasket is no different from the previous generation. In other words, if we were in China, there might be a new possibility here
With the first step of removing the parts, we can finally face the most important part of the S-Series iPhone - the motherboard!
After seeing this sandwich shaped motherboard, we have no difficulty in disassembling this sandwich shaped PCB motherboard (XS on the left and XS Max on the right)

It's time to talk about the camera. The s year usually brings the function upgrade of the camera, and apple does mention its new sensor many times
32% increase in sensor size at wide-angle end
The pixel size has also been updated, which brings better low light photography performance and contributes to the new "smart HDR"
Only time can tell us whether larger pixels can help it beat the pixel 2 camera that impressed us last year
One thing Apple didn't tell you about the new camera: with the sensor size expanding by 32%, the camera is more prominent. The protective shell of iPhone x should no longer be used on iPhone XS
After dissecting the brain and eyes, let's look at the parts that provide energy
XS encapsulates a 10.13wh battery (2659mah, 3.81v) and weighs 39.5g, which is slightly degraded compared with last year's iPhone X
This reduction in capacity is accompanied by a new battery design. Instead of splicing the two batteries into an L-shape into the machine, apple redesigned a single cell battery
The XS Max battery is the largest, providing 12.08 wh energy (3179 MAH, 3.80v) and 46.6g in weight, but it is not a single cell battery
This capacity is between S9 and S9 +, which is much smaller than note 9
Let's take a closer look at Apple's battery:
12 inch MacBook since 2015 Since announcing the use of trapezoidal batteries, Apple has increasingly sought to make full use of every space in its device chassis.
These patents show the solutions they have found to solve thorny problems such as thermal expansion, using different layer sizes and accurately folding and cutting electrode plates into complex shapes to adapt to these shapes.
Interestingly, this single cell is better at using space, but it has less power storage than x.
The extra corners and edges of a single battery in the XS will be vulnerable to external pressure - it will be interesting to see the performance of this new battery when aging.
Last year's revolutionary design soon became a new standard - XS and XS Max are equipped with sensor arrays for Apple's fancy face ID Technology.
It's time to get rid of the noisy crowd! The taptic engine and speakers appear in one component, but can be easily replaced separately.
XS Max has a more powerful feedback unit, but both taptic engines and iPhone 7 plus use the same Design of.
Speaking of this, the headphone speaker assembly almost exactly matches XS and XS max, and Max has only a little more additional speaker volume.
When we scraped the back of the phone, we found some interesting display chips and a pile of cables embedded in them.
It seems that the glass on the back still maintains a sandwich structure on the protrusion and frame of the camera, and there are many small welds.
Despite many improvements, the glass on the back remains the same structure as the iPhone 8 / iPhone x, which means that the whole backplane needs to be replaced for any small crack.
We have completed the disassembly of the two machines at the same time.
We suspect that this marks the beginning of a new era of iPhone Battery design - this carefully designed single battery idea only appears on the small XS, but we may see it again soon. IPhone XR, are you ready?
Thank you very much for your home in Sydney, Australia Circuitwise, and our best brother Creative Electron And the X-ray cameras they provide.
Oh, plus: it's time to give an overall repairable score.
