What to do if the case of the Xiaomi Redmi phone bent: causes, repairs and prevention

Did you take the Xiaomi Redmi out of your pocket and notice that the body was deformed? Or did the screen become a boat after the fall and the back cover bend when pressed? Deformation of the body is a common problem in smartphones with a metal or plastic frame, especially after mechanical impacts. In this article, we will discuss why this happens, how to assess the extent of damage and what to do depending on the model (Redmi Note 12, Redmi 10, POCO X5 and others).

It’s important to understand that even a slight bending can lead to hidden breakdowns, from disruption of the plume contacts to cracks on the motherboard. We won’t advise “just straighten the body with pliers” (this is guaranteed to aggravate the problem), but we will offer proven methods – from diagnostics to professional repairs, and you will learn how to prevent deformation in the future and which Redmi models are most vulnerable to such damage.

Why Xiaomi Redmi’s body bends: the main reasons

The deformation of the case rarely occurs on its own — usually the result of a combination of factors. Here are the key reasons why your Xiaomi Redmi could have floated:

• 📱 Mechanical impact: falling on a hard surface (especially on an angle), strong compression in a pocket or bag, impact.
• 🔥 Overheating: Long-term work in resource-intensive games (Genshin Impact, Call of Duty Mobile) or in direct sunlight can soften glue and plastic elements.
• 🔋 Battery bloating: if the body is inflated by a “boat” without visible impacts, the battery is to blame (especially important for models older than 2 years).
• 🏗️ Design features: a thin metal frame in the Redmi Note 11 or a plastic back cover in the Redmi 9A more susceptible to deformation.
• 🔧 Poor-quality repair: if you previously changed the screen or battery, the master could not properly fix the elements or use cheap parts.

The most dangerous situation is when the bending of the body is accompanied by problems in operation: spontaneous reboots, a network dump, a broken camera or touchscreen. This signals damage to internal components. For example, the Redmi Note 10 Pro often suffers from a display plume when the upper part of the body is deformed.

How to assess the degree of deformation: step-by-step diagnosis

Before you take action, you need to understand how serious the damage is. Take your smartphone and follow these steps:

1. Visual inspection: Place the phone on a flat surface (glass or table) with the screen up. If the case "swings" or there is a gap between the table and the back cover - the deformation is significant.
2. Check the screen module: swipe your finger around the edges of the display, and if you feel a step between the glass and the frame, the screen starts to move away.
3. Button test: press the power and volume buttons, and if they go down or press too tightly, the body has deformed the mechanism.
4. Check connectors: insert a charging cable, and if it hangs or doesn't come in, the USB-C connector will bend.

For accurate diagnosis, use the bubble level (an Android app, such as Bubble Level). Put your phone on the table and launch the application - if the bubble deviates by more than 2-3°, deformation.

⚠️ Warning: If the body is not only bent, but also has a characteristic crunch when you press the back cover, this is a sign of detachment of the battery!

Can you straighten the Xiaomi Redmi body yourself?

The Internet is full of tips for "straightening" the body with improvised tools, from books to visceral visors, 90 percent of which lead to a problem that is worse, especially if the deformity has affected the internal components, but in some cases, careful intervention is possible.

When you can try to straighten the body:

• ✅ Deformation is minimal (visible only on close inspection).
• ✅ The phone is stable, no problems with the sensor or camera.
• ✅ Plastic case (e.g. Redmi 9 or Redmi) A1).

When absolutely not possible:

• ❌ Aluminum housing (risk of cracks under load).
• ❌ There's a battery bloating.
• ❌ The phone overheats or spontaneously shuts down.

If your case fits the first three points, you can try the heating and pressure method:

1. Remove the back cover (if it is removable) and the battery.
2. Place the phone between two soft tissues (such as a microfiber).
3. Cover with a heavy book (no more than 1-1.5 kg) for 10-15 minutes.
4. Check the results. If there's no improvement, don't increase the weight.

💡

If after "rectification" the phone began to warm up more, immediately disassemble it and check if the motherboard skewed. Overheating may indicate a short circuit!

What to do if the body is bent due to a bloated battery

If the back cover of Xiaomi Redmi is blown up by a boat, and you hear the characteristic crunch when you press it, it's the battery's fault. This is critical: lithium-ion batteries can ignite when they swell.

1. Turn off your phone immediately and don’t turn it on.
2. If the battery is removable (e.g. in the Redmi 4X), remove it in gloves.
3. Place the phone in a non-combustible container (such as a metal pelvis) for 24 hours – this is the time to discharge the capacitors.
4. Contact a battery replacement service center. Don't use cheap batteries, just original batteries or certified batteries (e.g., ZMI).

⚠️ Warning: If the battery is so swollen that the back cover is cracked, don't try to glue it with superglue. When heated (for example, during charging), the glue can release toxic fumes or ignite.

Professional Repair: When to Contact the Service

If self-care has not helped or the deformation is serious, it is time to contact specialists.

• 🔧 The body is bent along with the screen module (seeing cracks in the glass or distortion of the image).
• 📶 After the deformation, the network is missing, Wi-Fi or Bluetooth is not working (an antenna is damaged).
• 🔋 Battery swollen, but not removable (requires a soldering station to replace).
• 🎯 Deformation near the camera – this can knock focus (especially relevant for the Redmi Note 11 Pro)+ 108MP camera).

The cost of repair depends on the model and the degree of damage:

• Replacement of the hull: from 2000 ₽ (plastics up to 5,000 ₽ (aluminum + glass).
• Straightening on a professional stand: 1500–3000 ₽.
• Screen replacement + body: 6,000-12,000 ₽ (model-wise).

Where to look for service:

• Xiaomi official centers (warranty 6-12 months, but more expensive).
• Local workshops with good reviews (cheaper, but check the certificates).
• Salons (for example, Messenger or MTS) - often give discounts for repairs when buying a case.

How to prevent deformation of the body in the future

Even if you have managed to fix the problem, it is worth taking measures to prevent it from recurring.Here are 7 rules that will prolong the life of your Xiaomi Redmi:

• 📱 Use a hard case with reinforced angles (for example, Spigen Tough Armor or Ringke Fusion-X). Plastic "silicones" do not protect against bends.
• 🔋 Do not charge the phone under the pillow - overheating weakens the glue that holds the body together.
• 🚫 Avoid screen pressure: Don’t put your phone in the back pocket of your jeans or sit on it.
• 🔄 Change the battery every 2-3 years, even if it's still on charge. Old batteries swell and warp the case.
• 🌡️ Do not leave your phone in the sun (e.g. on a torpedo in your car) The maximum operating temperature for Redmi is 45.°C.
• 🔧 Trust repairs only to certified craftsmen. Cheap screen replacement often results in deformation of the body.
• 📦 Keep your phone in a separate compartment of your backpack, not with your keys or headphones.

Pay special attention to the choice of case. For example, for the Redmi Note 12 with a thin body, a model with a built-in metal frame will suit, UAG Monarch, which distributes the load when falling. POCO X5 with a plastic back cover, it is better to choose a case with stiff ribs.

💡

The most common cause of Xiaomi Redmi case deformation is a combination of a thin metal frame and a bloated battery. Regular battery diagnosis (AccuBattery app) will help prevent the problem.
