Many users are faced with the need to access the interior space of their smartphone. Most often, the question of how to open the lid on Xiaomi arises when replacing broken glass, installing a battery or cleaning the device from dust. Modern Xiaomi models, such as the Redmi Note or the flagship Mi, are most often equipped with glass panels fixed on adhesive basis, which requires a special approach to dismantling.
Incorrect opening actions can cause damage to plumes, cracks in glass or even battery failure. The tightness of the case is not only a protection against moisture, but also a factor that makes disassembly difficult. Before you start active actions, you need to make sure that you have the right tools and understand the design of your model.
In this article, we will take a closer look at the process of removing the back panel, paying attention to the nuances of working with adhesives and fragile components. You will learn how to safely disconnect the plumes and what to do if the lid does not lend itself. Remember, self-disassembly can deprive you of warranty service, so weigh the risks.
Preparation of the workplace and necessary tools
A high-quality disassembly of the smartphone begins long before the first movement of the screwdriver. You need to organize a clean, well-lit space where small screws and details are not lost. The ideal option is an antistatic mat, but a regular table covered with light fabric will do. On a dark surface, it is easy to lose tiny screws, which can turn a simple repair into a multi-hour quest.
The toolkit should be specialized, ordinary stationery knives or rough screwdrivers can cause irreparable damage.
- 🔥 Suction cup or special screen opener (necessary to create the initial gap).
- 🔥 Plastic mediators or shoulder blades (so as not to scratch the frame and glass).
- 🔥 A set of precision screwdrivers (usually Pentalobe or Phillips cross-haired).
- 🔥 Hair dryer or thermostole (to soften glue).
Pay special attention to safety. Before any work begins, you need to turn off the device. If the battery is fixed, which is typical for most modern Xiaomi, the risk of short circuits with careless handling of tools remains high. The use of metal objects near the battery is strictly prohibited in the first stages of disassembly.
💡
Use a magnetic mat or a piece of paper with drawn cells to spread the screws in order of their extraction – this will save hours when assembled.
Warming the case: why it is necessary and how to do it correctly
The back cover on Xiaomi smartphones, whether it's a budget Redmi or a premium Mi, is attached to a special industrial glue. At room temperature, this composition is very durable, and just trying to tamper with the panel will lead to its destruction. Heat treatment is a key step that makes the glue elastic and allows you to separate the glass from the frame without damage.
The heater is best suited to a temperature-adjusted building dryer or a normal household hair dryer at maximum power. Thermostol is also effective, but requires caution. Heat uniformly throughout the device for 2-4 minutes. Surface temperature should not exceed 80-90 degrees Celsius, so as not to damage the internal components or display.
⚠️ Warning: Do not direct hot air to one point for too long, especially to the area of the camera or speakers, as plastic optics or membranes may warp from overheating.
You can check readiness by carefully trying to lift the edge of the glass with a suction cup. If you feel resistance, the heating procedure should be repeated. Xiaomi Mi 11 and other models with curved edges require more careful heating of the side faces. Uneven heating can cause the glass to burst from temperature voltage.

The process of separating the back panel from the frame
Once the glue is heated, the most critical moment comes: Set the suction cup at the bottom of the back cover, closer to the center, but not to the camera. Pull the suction cup up, creating tension, and insert a plastic mediator into the resulting microscopic gap. Don't use the force with a jerk, act smoothly.
Move the mediator along the perimeter, gradually cutting through the adhesive layer. It is important to constantly monitor the depth of the tool's immersion so as not to touch the internal plumes or the battery itself. In models with wireless charging, there may be an additional coil under the lid, which is also glued. Mechanical damage to the battery can cause it to ignite, so be extremely careful in the center of the case.
If the lid is very tight, don't be afraid to add a little more heat. Often users make the mistake of trying to tear the panel off immediately after one warm-up. The glue can freeze faster than you can get through the whole lap, so keep the hair dryer on hand. Unplug the lid completely only after making sure it's free around the perimeter.
☑️ Algorithm for cap removal
Disconnecting plumes and access to the insides
When the back cover is removed, you have access to the main board and the battery, but you can't rush the components off, so the first thing you need to do is disconnect the battery plume from the motherboard, and that will turn the device off and keep you from accidentally crashing with other connectors.
Use a plastic blade or finger to turn off the plumes. Metal tools are undesirable here, as you can damage the connector contacts or the plume itself. Carefully pull the connector up. In some Xiaomi models, the connectors can be additionally fixed with a metal clipping bar that you need to pre-screw.
Now you can start to diagnose or replace parts, and if you want to replace the battery, look for special retracting tongues that are often provided by the design, and if they don't, you'll need to use a suction cup to gently lift the battery.
| Xiaomi model | Type of lid attachment | Difficulty autopsy | Availability of wireless charging |
|---|---|---|---|
| Redmi Note 10 | Glue + screws | Medium | No. |
| Xiaomi Mi 11 | Glue (glass) | Tall. | There is. |
| Poco X3 Pro | Glue + screws | Medium | No. |
| Xiaomi 13 Pro | Glue (ceramics) | Tall. | There is. |
💡
Always turn off the battery plume first before touching other components of the board.
Frequent mistakes and risks in self-disassembly
Self-repair is always a risk. One of the most common mistakes is using excessive force. If a part doesn't go, you either haven't finished the glue or forgot to unscrew the hidden screw. In Xiaomi smartphones, screws can hide under stickers, port plugs, or even under a tray. SIM-map.
Another critical error is the damage to the plumes when the mediator is injected carelessly. The plumes in modern devices are very thin and run close to the edges of the housing. Damage to the plume of the display or the main camera often requires expensive replacement of the entire module. Restoring the ragged contacts at home is almost impossible without a microscope and a soldering station.
⚠️ Warning: A bulging battery cannot be pierced or bent. If the lithium polymer battery shell is damaged, instantaneous ignition can occur.
And the loss of waterproofing is also worth mentioning, because even if you carefully remove the lid and put it on a new glue, you can't restore the IP68 factory level, and after this repair, you should protect your phone from water and dust much more carefully than before.
Assembly of the device and check of performance
After performing all the necessary manipulations inside the case, the assembly stage begins. Before applying a new glue or installing the lid, be sure to check the device's health, plug the battery plume and try to turn on the smartphone. Check the touchscreen, sound, vibration and camera performance.
If everything is working correctly, degrease the edges of the frame and the inside of the lid with alcohol or a special degreaser. Apply a new layer of glue (B-7000 or special adhesive tapes) with a thin, uniform layer.
Press the lid around the perimeter and lock the device with rubber bands or in a special press for 1-2 hours until the glue is completely dry. Do not turn the phone on or load it during this period. The adhesive layer should gain maximum strength to ensure a tight fit.
