Hi all, I was doing a Surface Book 2 battery replacement. First time doing any actual hardware repair work on a Surface....

So I finally got an iPhone 6 Plus, I opened it up to check it out. During the disassembly I found a few QC issues, one...

Maybe, but the accuracy is not guaranteed since it is not possible to calibrate 3D Touch without Apple's tools.

It is for grounding and RF shielding, the performance will degrade a little bit, but in areas with decent cell coverage, the degradation is minimal.

Screen dimming is part of the overheat protection, it is overheating or at least it thinks it is.

I believe this is a manufacturing defect, the black paint behind the glass has been scuffed off maybe by production fixture. A tiny amount of paint scuffing off may allow light reflected across the front glass to leak out the edges. Ask Apple if they would offer exchange or repair. It is possible that they will refuse citing this is just a cosmetic issue. If Apple won't fix it for free, in my opinion this tiny defect is not worth fixing, since you'll need to replace the whole display, maybe just paint it over using a black sharpie.

If there is water damage without destroying the sensor chip and the security chip, it is very possible to repair. Just clean the board, find and replace whatever components shorted and corroded.

Buy AppleCare+, you can still buy it within 60 days of device purchase, I don't think it is possible to exceed 60 days for this device yet. It costs 89 euros and each whole device insurance claim is 99 euros. This saves you 200 euros and gives you 100% factory quality repair. Or wait for the Apple's self-service repair to come to Europe. It will guarantee 100% factory quality repair for the screen, you don't have to worry about Touch ID or True Tone. Then go outside to repair the back glass for cheap. Both solutions costs way less than Apple's current quote and gives you total or almost total factory quality repairs, you just need to make perfect timing for the offer availability.

Yeah it's the cable. It doesn't really matter exactly which part is broken as you'll need to replace the whole display assembly anyway.

You need to pair the Touch ID button to the new board, which only Apple can do.

What do you mean by "fix"? To fix something, it needs to be broken first.

Soldering will be required, so this is at least a level 3 repair.

The 8897 is for wifi and the 8782u is for controller. It has NO Bluetooth feature, Xbox One wireless controller is based on custom wifi protocol.

Is this the same bottom cover as the AirPort 802.11ac?

This is freely replaceable, no special lockdown present.

To be honest I don’t this is “almost impossible to replace. It is literally right in the center once your take off the screen.

Also it doesn’t seem to cause the device to brick either. Most of the time you get inaccurate clock whenever you unplug the computer from power and that’s it.

Probably not for redundancy, but for capacity.

CR2032 is too thick for this model, so they used 2 CR2016s instead, more or less the same thing.

Those are likely to be hardware debug leftovers, or devkit leftovers. Extra hardware features are needed for game developer kits, like a CMOS battery, extra buttons and displays for example.

Xs has 4 antennas, while the XR only has 2.

Easy, you are supposed to desolder the battery and the dock flex first, remove the logic board then access the battery.

Look at the CPU heat spreader, it is much thicker than previous models, is it possible that this is some kind of mini flat heat pipe?

Yeah it is just a case ventilation fan, it doesn’t blow any heatsinks directly. Although with the very low TDP of the processor, a case fan with radiator type heat sink should do the job.
