Close the power button on the Xiaomi phone: 3 proven ways

The power button on Xiaomi smartphones is one of the most vulnerable elements: it fails due to mechanical damage, moisture or trivial wear. If your device stops responding to a press, do not rush to carry it to the service center. In 80% of cases, the problem can be solved by locking the contacts of the button manually - this is a temporary solution that will bring the phone back to life until full repair.

In this article, you will find step-by-step instructions for different Xiaomi models (from Redmi Note 4 to POCO F5), contact layouts, and unique tips for diagnosing a malfunction without disassembling the case. We will analyze both the “old-fashioned” method with a needle and professional methods using a soldering iron. Importantly, all the manipulations you perform at your own risk - improper circuiting can lead to short circuit or damage to the motherboard.

Why the power button breaks: 5 main reasons

Before you get to the soldering iron, it is worthwhile to understand what exactly went wrong. At Xiaomi, the power button often stops working for the following reasons:

• 🔧 Mechanical wear – plastic latches inside the button wear off after 20-30 thousands of clicks (typical for older models) 3 years).
• 💧 Corrosion of contacts - oxidation after moisture enters (even if the phone does not sink, high enough humidity in the room).
• 🔌 The plume break - thin tracks connecting the button to the board are rubbed with frequent falls.
• 🔥 Overheating of the board – if the phone overheated frequently (for example, during games), solder on the contacts could melt.
• 🛠️ Poor-quality repairs – after replacing the screen or battery, the wizard sometimes damages the flexible plume of the button.

How do you know if the problem is in the button, not the motherboard?

1. Connect your phone to charging – if a charging indication appears (a light bulb or battery icon) but the screen doesn’t turn on, the problem is more likely in the button.
2. Try to run your phone through Fastboot (Put Volume Down + Power for 10 seconds). If the menu appears, the button is partially activated.
3. Connect your phone to your PC – if the computer makes the connection sound USB-devices, but the screen remains black, the plume or contacts are to blame.

Method 1: Temporary closure with a needle (without disassembly)

The simplest method that works is if the button is physically drowned in the case or not clicking. You don't have to disassemble the phone, which is a thin metal object, suitable for models: Redmi 4/5/6/7/8/9, POCO X3/F3, Mi A1/A2.

Instructions:

1. Take a thin needle or paper clip (diameter not more than 0.5 mm).
2. Carefully insert it into the gap between the button and the phone body.
3. Push a little deeper, trying to move the button mechanism inside.
4. Hold for 5-10 seconds – if the contacts are not oxidized, the phone should turn on.

If the method worked, but the button stopped responding again after a few hours, the problem is mechanical wear, in which case only changing the button or permanently closing the contacts on the board will help.

💡

Before manipulating the needle, disconnect the phone from charging - this will prevent short circuits when other contacts are accidentally touched.

Method 2: Close contacts on the board (with disassembly)

If the needle doesn't work, you'll have to take your phone apart and close contacts directly, which is a good way to do it for all Xiaomi models, but it requires care.

• 🔧 Plastic blade for disassembly
• 🔥 soldering iron (power not more than 30 W) or tweezers
• 🧲 Magnetic screwdriver (for screws) T3/T4)
• 📄 Whipcloth without pile and alcohol to clean contacts

Step-by-step:

1. Remove the back cover. Most Xiaomis have it on the latches, gently shovel around the perimeter. On the metal-body models (Mi 5/6/8), unscrew the screws first.

Put the phone back together.

If the phone turns on after the circuit, but the button still doesn't work, the problem is the plume or the control chip, in which case you will need to replace the parts.

Method 3: Software enabled via Fastboot (if the button is partially working)

If the power button sometimes works (for example, the phone turns on on on the 10th try), you can try to run it through Fastboot or EDL-It's a method that doesn't require disassembly, but it needs a computer and a computer. USB-cable.

Instructions for Windows:

1. Install Platform Tools (includes fastboot and adb).
2. Connect the phone to the PC.
3. Press Volume Down + Power for 10 seconds to log into Fastboot.
4. In the command line, execute: fastboot devices If the phone is determined, type: fastboot continue It will force the system to start.

If you've never soldered before, work out on unnecessary fees (like from an old phone or a PC mother card). Mistakes when working with Xiaomi are expensive - repairing a burned-out board can cost up to 70% of the price of a new phone.
