How to gently open the lid on Xiaomi phone: from Redmi Note to POCO F5

Removing the back cover on Xiaomi smartphones is a challenge that users face when replacing the battery, repairing the camera or cleaning up dust. Despite its apparent simplicity, the procedure requires care: improper actions can lead to damage to the plumes, cracks in the glass or loss of leakage. In this article, we will discuss all the ways to open the lid – from classic models Redmi Note 8 Pro to flagship Xiaomi 14 Ultra, take into account the features of adhesive and snapping designs, and also warn against typical errors.

It’s important to understand that modern Xiaomi smartphones (especially the POCO and Mi series after 2020) often come with a waterproof seal that makes it difficult to disassemble. If you’ve never repaired equipment, you’d better contact a service center — but if you decide to act on your own, our instructions will help minimize risks. We’ll also tell you what tools you need, how to prepare the workplace and what to do if the lid is stuck to the case.

Preparation for disassembly: tools and security measures

Before you start removing the lid, make sure you have everything you need, and not even one tool can turn a simple procedure into a nightmare with a damaged body or display.

• 🔧 Plastic blades (2-3 pieces) to separate latches. Metal mediators will not work: they scratch the body.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C) Household hair dryer is weak, but it will do.
• 🧲 Suction cups (1-2 pcs) - help lift the lid after heating.
• 📦 The screw container is designed to keep the small parts intact.
• 🧴 Isopropyl alcohol (90%+) — Acetone or solvent cannot be used, they destroy seals.

Also, prepare a clean, well-lit workplace. A table with a white tablecloth (to see the screws falling) and a desk lamp is perfect. Make sure there are no sources of static electricity nearby, it can damage the motherboard. If you're dealing with wireless charging (such as the Mi 11 or the POCO F4 GT), be especially careful: there's a coil under the lid that's easily damaged by a shoulder blade.

⚠️ Warning: Don't try to open the lid with a knife, screwdriver or other sharp objects. Even a little pressure can puncture the battery, leading to a fire or explosion. In 2023, several Redmi models have been reported to have been hit by a fire or explosion. 9A and POCO X3 NFC.

Types of mounting the lid on Xiaomi: how your model differs from others

Xiaomi smartphones use three main types of mounting the back cover, and this depends on the complexity of disassembly.

If your model is not listed in the table, check it on the GSMArena website under the "Construction" section. Note the presence of glass on the back - such models (for example, Xiaomi 13 Pro) require special care: glass can crack when heated unevenly.

In aluminum-body models (like the POCO F1 or Mi 8), the lid is often mounted on plug screws, and you need to tweak them carefully and twist the T3 or T5 with a screwdriver, and if there are no plugs, it's likely to be a latch lid.

Step-by-step: how to remove the lid on Xiaomi with adhesive fastening

Consider the universal algorithm for most modern models (the Redmi Note 11 Pro+ example).If your smartphone is a different type of mount, skip unnecessary steps.

1. Turn off the phone and remove it. SIM-The battery must be charged by 20 to 30 percent, which will reduce the risk of short circuits in the event of accidental damage.
2. Heat the edges of the lid with a hair dryer for 2-3 minutes, holding it at a distance of 5-7 cm. The temperature should be comfortable for the hand (do not burn!).
3. Stick the suction cup to the bottom of the lid (not the camera glass!). Pull up with moderate force - a gap of 1-2 mm should appear.
4. Put a plastic blade in the gap and gently run it along the edge, dissolving the latches. Do not go more than 3-4 mm deep - there may be plumes inside!
5. Repeat heating for the top and side parts, gradually detaching the cover. If you feel resistance, do not press harder, heat the problem area again.
6. Remove the lid when all the latches are disconnected. Don't pull the plumes! In NFC models, the antenna can be glued to the lid.

If the lid fails, check:

• 🔋 Did you forget to turn off your phone? The device on can block the latches because of the voltage on the contacts.
• 🌡️ Is the glue hot enough? Try to raise the temperature to 80.°C (but not higher!).
• 🔍 Are there any hidden screws? Look around the case again -- sometimes they're hidden under logo stickers.

Is the phone off?

Whether extracted SIM-memory-card?

Are the spatulas and suction cups ready?

Are the edges of the lid heated with a hair dryer?

Is there any isopropyl alcohol nearby for cleaning?

⚠️ Note: On Xiaomi models with glass back panels (e.g. Mi 11 Ultra or POCO F3 GT) Do not use metal tools to tamper with, glass can crack even from a plastic shoulder blade if pressed too hard, in such cases it is better to use the threads for disassembly (sold in tool stores).

What to do if the lid is not removed: common problems and solutions

Even if you follow the instructions, you can face difficulties. Let's look at typical scenarios and how to solve them:

1.The lid "stuck" to the body

If the hair dryer heats the lid, it's likely that the glue is too old or that the phone has been in high humidity.

• 🔥 Increase heating time to 5 minutes by focusing on the problem area.
• 🧊 After heating, put your phone in the freezer for 10 minutes (only if the battery is removed.
• 💧 Apply a drop of isopropyl alcohol along the seam - it will dissolve the glue without damaging the sealer.

2.Cock heard, but the cover is not removed

That means the latches break, but the glue still holds.

• 🔧 Check if there are any unconnected latches in the upper part (near the camera).
• 📱 Try gently scrolling the shoulder blade along the edge, as if "sawing" the glue.
• 🚫 Don’t pull the lid by force – so you will tear off the plumes or damage the antennas.

3.A ripped plume is visible after the lid is removed.

If you see a broken wire, immediately disconnect the battery (unplug the power plume).

• 📸 Take a picture of the damage – it will help the master in the service.
• 🔌 If the plume of the display or camera is broken, the phone may not turn on!
• 💰 The cost of repairing the plume in the service: from 1,500 to 5,000 ₽ (model).

💡

If the lid is removed too easily, make sure there is any glue left on the case. The residue can get inside and cause a short circuit. Remove the glue with alcohol and a napkin without pile.

Features of disassembling popular Xiaomi models

Each Xiaomi series has its own nuances, and we have collected key points for the most common lines:

Redmi Note 10/11/12

The lid is attached to the glue + latches, but the seal is not glued to the body. The main danger is the plume of the side buttons, which is easy to tear off when you remove it sloppy, and we recommend starting the disconnection from the bottom (near Type-C), where the latches are smaller.

POCO F3/F4/F5

These models have a glass back panel that cracks when heated unevenly. Use disassembly threads instead of blades. Also be careful with the coil of wireless charging, which is located in the center and glued to the lid.

Xiaomi 12/13/14

Flagships have a double layer of glue and a waterproof seal.

• Heated to 80°C for 5 minutes.
• Use two suction cups (for uniform lifting).
• Cleaning of glue residues with alcohol before reassembling.

In Xiaomi 13 Ultra additionally have screws under the plugs near the camera – they need to unscrew T3-screwdriver.

Redmi 9A/9C/10A

Budget models with a plastic lid on the latches, the glue is missing, but the latches are fragile, the main difficulty is the battery plume, which is easy to tear off, and we recommend that you disconnect it immediately after you remove the lid.

💡

On NFC models (such as the POCO X4 Pro or Redmi Note 11 Pro), the wireless payment antenna is often glued to the lid. Don't pull it when disassembling, it can damage the module.

How to put your phone back together: Tips for sealing and glue

If you successfully removed the lid, but do not know how to return everything to its place, follow these recommendations:

1. Clean the case and the lid of the old glue with isopropyl alcohol.
2. Check the seal. If it is torn or deformed, replace it (price of a new one - from 300) ₽).
3. Put on a new glue. That's fine: 📦 Double-sided scotch 3M (thickness 0.2–0.3 mm). 💧 Liquid glue B-7000 (squirt). 🔧 Special glue for smartphones (for example, Tesa 61395).

Line the lid.

Hold the latches.

Check the leakage.

If you don't plan on using your phone in wet conditions, you can do without glue, because the latches will hold the lid, but remember that dust and moisture can get in, which will eventually lead to oxidation of the contacts.

⚠️ Note: On models with liquid cooling system (e.g, POCO F5 Pro or Black Shark) don't use too much glue. It can block the circulation of fluid, which will overheat the processor.

When you should not open the lid yourself

Some situations require professional intervention.

• 🔋 Your battery is swelling, it's dangerous.
• 💧 The phone has been in water and you're not sure if it's dry. corrosion can damage the board.
• 🔧 You have a model with a glued lid (for example, Xiaomi Mix Fold or a lid). POCO M4 Pro).
• 📱 Phone guarantee - disassembly cancels it.
• 🔍 You can’t determine the type of attachment or are afraid of damaging the plumes.

If you do decide to take a risk, record the process on video, which will help the service master understand what exactly you damaged (if something goes wrong), and also save all the screws and parts in individual bags - losing even one screw can lead to loss of water resistance.

💡

Before disassembling, take a picture of the location of all the plumes and screws, which will greatly simplify the reverse assembly, especially if you are first doing repairs.
