Disassembling the Xiaomi Redmi Note 8T is a challenge that owners face when replacing a battery, repairing a camera or cleaning from dust. However, improper removal of the lid can lead to cracks in the case, damage to the plumes or loss of leakage. This model, released in 2019, has design features that are important to consider: there is no removable battery, and the lid is glued around the perimeter.
Unlike Xiaomi’s flagship models, which often use latches, the Redmi Note 8T uses a medium-strength adhesive layer, which complicates the process, but makes it possible even without professional tools — provided you are careful. In this article, you will find a step-by-step photo instruction, a list of necessary tools, and a list of typical errors that lead to breakdowns.
If you’ve never taken a smartphone apart before, we recommend that you first read the FAQ section, which provides answers to the most common questions about risks and alternative methods.
What you need to analyze: tools and materials
Before you start removing the lid, prepare the workspace and tools.
- 🔧 Plastic mediator (or guitar) - to separate the lid without scratches!
- 🔥 Dryer (from 1500 watts) - for softening the glue, even a household, but better building with temperature control.
- 🧲 Suction cup (3-5 cm in diameter) - helps to lid after heating. Alternative: Scotch with a loop.
- 📏 Thin screwdriver (cross, 1-2 mm) - for unscrewing screws under the lid.
- 🧴 Isopropyl alcohol (90%+) — Acetone or solvent cannot be used, they will damage the plastic!
In addition, the following may be useful:
- 📱 Spare clips for cap fixation (sold in repair kits).Redmi Note 8T 12 pieces.
- 🔋 New battery (if the purpose of the analysis is to replace) The original has an article MB-J11B.
- 📸 Loop or macro lens – to inspect plumes for damage.
If you don't have a hair dryer, you can use hot water (not boiling water!), but this method is risky: moisture can penetrate the body. The alternative is to leave the smartphone on the heating battery for 10-15 minutes, but the effect will be weaker.
⚠️ Warning: Do not use a knife or other sharp objects to lash the lid! the risk of scratching the body or cutting the plume of the touchscreen is 80%.
Risks in self-discussion: what to expect
Even if you take the lid off carefully, you're likely to run into problems, and here are the most common consequences of a failed deconstruction:
| Problem. | Reason. | How to avoid |
|---|---|---|
| Cracks on the lid | Pressure too high with mediator or overheating with a hairdryer (>80°C) | Heat for no longer than 2 minutes, use plastic tools |
| Touchscreen detachment | Damage to the plume when the cover is under the screen | Start separation from the bottom (near the USB-C connector) |
| Loss of leakage | Damage to rubber seals or improper assembly | Check the integrity of seals before assembly |
| Vibration's not working. | Displacement or break of motor contacts | Do not pull the lid sharply - the motor is located in the upper part |
The Redmi Note 8T has a brittle plastic body compared to the metal models of the same line, which, when heated, becomes more elastic, but it can easily deform, and if you notice that the lid started to play after disassembling, it's a sign of damage to the latches.
Another thing is, this model has a battery glued to a midframe, and if you want to replace it, be prepared for the extra manipulation of heating and using a plastic blade.
💡
Before disassembling, completely discharge the battery (up to 0%) and leave the smartphone off for 2-3 hours. This minimizes the risk of short circuit in case of accidental battery damage.
Step-by-step: how to remove the cover without damage
Follow the algorithm in strict order. If a step fails, don't make any extra effort, read the instructions or go to the question section.

Step 1. Heat the body.
Turn on the dryer at a medium power (temperature ~60-70°C) and evenly warm the back cover for 1.5-2 minutes, paying special attention to the edges. Keep the hair dryer at a distance of 5-7 cm so as not to overheat the plastic. Sign of readiness: the cover will become a little softer to the touch.
Step 2: Separation of the cover
Stick the suction cup to the bottom of the lid (above the Redmi logo) and pull up. If the lid doesn't lend itself, gently tuck it in with a plastic mediator from the same edge. Once you have a gap of 1-2 mm, swipe the mediator around the perimeter, separating the glue. Take your time! There are latches on the top and sides, and you need to snap them one at a time.
Step 3. Remove the lid.
When all the latches are snapped, remove the lid and put it aside. Underneath it, you'll see:
- 🔋 Battery with connected plume
- 📷 Main camera module (3 lenses)
- 📶 Antenna contacts (do not touch them with metal objects!)
- 🔊 Dynamician and microphone
Step 4: Shutting off the battery
Before you continue the analysis, be sure to disconnect the battery!
- Unscrew 2 screws next to the battery connector (cross screwdriver).
- Carefully tuck the black plume with a plastic spatula and disconnect it.
⚠️ Warning: If you don't turn off the battery before further manipulation, the risk of short circuits when you accidentally touch the contacts is 90!

Smartphone Builder: How to Avoid Mistakes
Building the Redmi Note 8T after disassembly is a task no less important than disassembling it.
- 🔌 Unconnected battery plume – the smartphone will not turn on.
- 📶 Displaced antenna contacts – network signal will deteriorate.
- 🔊 Poorly recorded speaker – wheezing or quiet sound will appear.
Assembly order:
- Make sure all plumes are connected (battery, camera, touchscreen).
- Check the integrity of the rubber seals around the camera and the speaker.
- Apply a new adhesive layer around the perimeter of the cover (you can use double-sided tape with a thickness of 0.3 mm).
- Press the lid, starting at the top, and snap all the clips.
- Turn the screws (do not pull!).
After assembly, turn on the smartphone and check:
- 🔋 Charging (connect the charger).
- 📷 Camera operation (take a test shot).
- 📞 Network signal and Wi-Fi.
- 🔊 Sound in speaker and microphone (record voice message).
If something doesn't work, re-disassemble the smartphone and check the connection of the corresponding plumes, and in 70% of cases, the problem lies in poor contact.
💡
Use the original screws! screws from other Xiaomi models may not fit in length and damage the motherboard.
Alternatives to self-review
If you are unsure of your abilities or are afraid of damaging your smartphone, consider alternative options:

Informal service centres
Pros:
Cons:
- ❌ Risk of using unoriginal spare parts.
- ❌ There is no guarantee of work (or minimum).
3. Purchase of used smartphone for spare parts
If your Redmi Note 8T has several malfunctions (for example, a broken screen + a dead battery), sometimes it is cheaper to buy a similar model with other breakdowns on Avito or Yula and use it as a donor.
When choosing a service, pay attention to reviews and ratings. Ask for certificates of masters (if it is an official center) and ask what parts will be used.
