First look at the real machine first
The first step is to remove the outer casing, and the whole is not bother, and it can be easily set with plastic.
Fortunately, the rear shell of Nexus 5 did not use the adhesive fixed, but used a simple snap-in, it is not difficult to remove it.
Above the battery is NFC patch, next to wireless charging components
I can see the battery after I get the NFC and the wireless charging module.
Start removal screw
Although the battery is fixed, the bond is not particularly firm, and if iFixit smashes a few times, it is easy to pull it with a cripple, and there is no damage to the battery.

Red circle: Don't let your little pet close to the battery
The crow is again played again.
The speaker section only uses several screws to fix, and the screw can be removed directly, and there is no cable to connect.
Despite two outgoing holes, NEXUS 5 is still a standard single speaker design.
The motherboard of Nexus 5 is located on a small board at the bottom of the fuselage in a two-stage design, speaker and LED lamp.
Red is a microphone line
Orange is LED indicator cable
The yellow part is a Micro USB interface
The green part is the contact of the antenna
The blue part is the contact of the speaker
After the screw is removed, the motherboard will be removed.
Above the motherboard has a small motherboard responsible for NFC and wireless charging, and remove it after removing the cable.
There is also a metal shield in the upper side, which should be to avoid signal interference.
The use of the NFC controller (red part) from BoTong, the specific model is BCM20793M
Let's take a part of aware of the motherboard:
The red part is 16GB NAND flash particles from SanDisk, numbered SDIN8DE4.
The orange part is from Qualcomm WTR1605L LTE / HSPA + / CDMA2K / TDSCDMA / EDGE / GPS RF chip
The green part is from Qualcomm PM8841 power management chip
The yellow part is from BCM4339 Wi-Fi control chip, integrated power management and signal enlargement, support 5GHz band.
The blue part is Anhua's RFI335 chip, which is unknown.
The pink part is a six-axis gyroscope and accelerometer chip from Invensense.
The black part is Ak8963 electronic compass from Asahi Kasei
The red part is from the LPDDR3-1600MHz memory chip of Hissant, with a capacity of 2GB, numbered H9CKNNBPTMRLR-NTM; it and Qualcomm Snapdragon 800 processor is packaged together, so we can't see the Snapdragon 800.
The orange part is a high pass WCD9320 audio decoder
The yellow part is an ANX7808 from Analogix
The green part is Qualcomm PM8941 power management chip
The blue part is BQ24192 from Texas Instruments, which is responsible for charging and USB data transmission function.
The pink part is Anwa's ACPM-7600
The camera is still 8 million pixels, but the optical anti-shake design is joined, and ifixit indicates that the focus speed of this camera and the continuous shooting ability have obvious improvement.
Continue to remove small parts
From left to right, it is the earpiece speaker, headphone jack, and 1.3 megapixel front camera.
Ifixit indicates that the modular feel is good, it is very convenient to repair at least. But in the end, there is an unfortunate message, and the screen of Nexus 5 cannot be removed, because it is a whole with the front panel, if it is broken ...
By the way, look at the touch screen control chip, it is from S3350B of Synaptics
Family blessings
The final achievement of Nexus 5 is 8 points (full range of 10 points, 1 point is the most difficult to repair), which represents NEUXS 5 has a very high fixability. Specific performance in the following aspects:

2. Remove the battery after slightly heating the binder;
3, using standard cross screws;
4, the post-plastic cover is more strict, can only be opened with crowbar, but it is better than glue with glue;
