Owning Xiaomi smart gadgets has long been the norm, but even reliable tech sometimes requires intervention. Users often wonder how to open Xiaomi scales to replace power, clean contacts or try to fix the device after getting moisture. Modern models like the Mi Body Composition Scale or Mi Smart Scale 2 are designed to look monolithic, creating the illusion of being impossible to disassemble without damage.
In fact, the scale design allows for a neat opening if you know the location of the hidden screws and the right sequence of actions. Incorrect use of force can damage fragile glass or break plastic latches, so it is important to prepare before you start. In this article, we will discuss the dismantling process in detail, explain the necessary tools and explain how to avoid typical errors in maintenance of electronic scales.
It should be noted right away that disassembling the device yourself can void the warranty, so weigh all the risks. If the gadget is on warranty and just stopped turning on, it is better to contact an authorized service center. However, if the warranty has expired or the cause of the breakdown was mechanical damage, you have no choice but to act independently.
Preparation for the opening procedure
Before you start dismantling, you need to prepare the workspace and tools, you need a clean, flat surface with good lighting, so you don't lose small screws or damage the internal components, and the main tool for the work will be a thin plastic card or a special mediator to open the housings, because metal tools can damage glass or plastic.
Make sure that the battery compartment is not equipped with active power supplies. If the scales are still working, remove the batteries before any manipulations are initiated, which is critical for safety and preventing short circuits in case of accidental damage to the plumes.
- 🔧 Thin plastic card or mediator for opening
- 🔧 A small sized cross screwdriver (usually) PH0 or PH00)
- 🔧 Tweezers for extracting small details
- 🔧 New types of food items AAA or CR2032 (model-wise)
⚠️ Attention! Do not use sharp metal objects (knives, screwdrivers) to pluck the glass - this is guaranteed to lead to chips or cracks on the front panel.
It is also worth taking care of the screw folding capacity in advance, as they are very small and easily lost.Some Xiaomi models use screws of different lengths for different parts of the body, so it is recommended to lay them out in the order in which they were removed.
Features of the design of different models
The scale line from Xiaomi and the Mijia ecosystem is quite extensive, and designs may differ.Older models like the first version of the Mi Smart Scale often have a simpler mounting mechanism, while newer versions, including the Mi Body Composition Scale 2, use more sophisticated sealing systems. Understanding the type of your device will help you choose the right opening strategy.
Most of the time, the mounting is done by a combination of plastic latches around the perimeter and several screws hidden under rubber legs or stickers. Rubber legs are not only for (anti-slip) but also decorative plugs that hide fasteners.
Differences between 1 and 2 generation models
In the first model, the screws are often placed under four legs, and in the second version of the Mi Body Composition Scale 2, the design can be more monolithic, where the screws are hidden under a central sticker or require perimeter cracking without visible screws.> It is also important to consider the material of the upper platform: the top models use tempered glass, which requires special care when pressing, plastic versions are more forgiving to mechanical stress, but they are easier to scratch. Weighing model Type of attachment Location of screws Difficulty opening Mi Smart Scale (1 gen) Latch + 4-legged low Mi Body Composition Scale 2 Latches + Screws Under Legs/Sticker Average Mi Smart Scale (2020) Monoblock Missing (latches) High If you are not sure about the model, it is best to first carefully inspect the bottom of the device in bright light. Sometimes manufacturers hide one screw under a warranty sticker, which is a signal that the user does not want to disassemble. Step-by-step, the process of disassembling the bottom panel begins with the dismantling of the bottom plastic cover. Turn the scales and carefully examine the perimeter. Your task is to find all the mounting points. Start by removing the rubber legs if the screws are under them. Carefully tweez the edge of the leg with tweezers or a thin blade, trying not to tear the rubber. After screwing the perimeter, you do not open the slit from the top of the card, you can easily cross the slit to the 4th, and then you can easily open the card from the top of the slit, and then move it to the bottom card. Move around, gradually releasing the latches from all sides. If the case does not open, do not use excessive force - you may have missed one screw or sticker. When all the latches are released, the bottom panel should easily separate. If it holds, check if any plume is connected to it (although in most Xiaomi scales the display and board are fixed to the top, and the battery compartment is part of the bottom cover). After removing the bottom cover, your eyesight will easily be inspected. If the contacts are held, you will need to open the battery pack, you will not be able to open the lower compartment immediately. Oxidation is a common cause of inoperability. Use a cotton swab dipped in alcohol to clean the contacts. 🔋 Check the polarity of the battery installation 🔋 Make sure that the contact springs are not deformed. 🔋 Clean the contacts from oxides with alcohol 🔋 Check the integrity of the wires going to the sensors ⚠️ Attention! Avoid static electricity when working with electronics. Touch a grounded metal object before touching the board, so that sensitive chips are not damaged by a discharge. If you plan to replace the power connector or re-sweeten contacts, you will need a soldering iron.However, for most users, it is enough to simply replace the batteries and clean the contacts. The Xiaomi scale board is usually closed with an additional plastic casing that is attached to latches or screws. Sensor replacement and electronics repair If the scales show the wrong weight or don't turn on even with new batteries, the problem can lie in strain gauges. They are located at four platform angles and connected to the main board by thin wires. Wire break or sensor contact oxidation is a frequent malfunction after the device falls. To access the sensors, remove the top glass or plastic panel. This is the most risky stage, since the glass is attached to the glue or very tight latches. Heating the perimeter can help soften the glue, but you need to act carefully when you hit the sensor. If one of the sensors fails completely, it can be difficult to replace it, because it is difficult to find a component that is identical in characteristics. In such cases, it is sometimes easier to buy a new scale than to find a donor for parts. Assembly of the device and check the health After all the repairs or replacement of batteries, you need to assemble the device in reverse order. Make sure that all the plumes are connected correctly and to the end. A loosely connected connector can cause unstable work. When you install the bottom cover, first click the corners, and then walk along the perimeter, you need to show the new battery to the device, you need to turn on the s on the device for the slit, and make sure that you do not span your spanpanpantage. If the scales show "error" or unstable numbers, perhaps the platform is skewed. Twisted all the screws and put the rubber legs back in place. If the legs are lost stickiness, you can use bilateral scotch, but try not to block the screw holes. Frequently asked questions (FAQ) Can you open the scale Xiaomi without damaging the body? Yes, if you act carefully and use plastic tools. The main difficulty is to find all the hidden screws under the stickers or legs. The main thing is not to use force where the device does not open. What to do if the pins are damaged, if the weight is possible, if the problem is repeated from the weights, if the weights are not shown on the surface, if the weights are not damaged, if the weights are not damaged, then, if the weights can be repeated, if the weights are not show the weights are re-wiped. Which batteries are better for Xiaomi scales? The official recommendation is alkaline batteries of well-known brands. Using cheap salt batteries can lead to rapid discharge and risk of leakage of the electrolyte, which will damage the electronics of the scales. Will disassembling the scales violate the warranty? Yes, in most cases, violation of seals or the presence of autopsy marks (tool scratches, broken latches) is the reason for refusing warranty service.
