It got a dew-drop notch at the front and aura smoke design on the back looks stunning. The camera has a superb performance and is an ultimate allrounder.
So let's start the teardown...
Starting from the back of the device, the back cover is glued to the body using adhesive. By warming the back of the device, the adhesive becomes a little week and can be removed by using the hand tool to sneak between the panel.
Be careful while removing the back cover as the fingerprint sensor and its ribbon cables are connected to the back. So, detach the cable before separating the back cover from the device.
After removing the back panel, you can see the polycarbonate back. It is very stylish like most of the other Redmi devices. The polycarbonate back gives a great glass-like finish and reduces the weight of the device.
On the top, you can see a plastic bracket protecting motherboard, a massive 4000mAh battery in the middle and another plastic bracket protecting the sub-board PCB, which includes a micro-USB port, loudspeaker, and the vibration motor.
Now you can easily detach the fingerprint sensor. It is a high-quality sensor and is really fast in unlocking the device.
On removing the screws of the plastic bracket, it can be detached from the rest of the phone. The bracket has antenna pins attached to it. The bracket acts as a protection to the motherboard and other fragile parts. It also comprises of the camera and LED lenses and can be easily and cheaply replaced in case of any unfortunate scratches or breakage.
On removing the plastic bracket, the battery ribbon can be removed by unclipping from the board. It is always recommended to disconnect battery power for better security from short circuits.
The processor and ROM are protected under a steel bracket. The front and back camera is also attached to the motherboard by cables that can also be detached now.
The camera sensors are now visible along with the motherboard protected with a steel bracket. The smart AI Dual rear camera uses 1.25μm large pixels, which allows it to capture important moments in all their glory. The AI-powered portrait mode blurring helps you get the perfect shot. The AI camera has an AI scene recognition capability that can detect up to 33 scenes to optimize the photo in real-time.
The front side of Redmi 7 packs an 8MP AI sensor capable of taking stunning selfies and groupies. AI Beautify and AI background blurring accurately recognize facial features to create great portrait selfies.

Now let’s remove the battery. It is a huge 4000mAh high-capacity battery that can power the device for up to two days. It uses AI power-saving technology that allows you to use your phone for a long time without repeated charges.
The bottom part of the body has the sub-board PC which is protected by a hard plastic bracket screwed on top of it. By removing the bracket we can see the main loudspeaker of the device. Even though the device has a single speaker, it is loud and clear.
After unscrewing the sub-board PCB can now be removed from the body. The sub-board contains many connectors. It also holds the Micro USB port that can be used for charging and file transfer.
Now what remains is the vibration motor. This is a high-quality motor, responsible for the vibration of the device on calls and also for haptic feedback.
