How to turn off the battery on Xiaomi: all the ways and nuances

Disabling the battery on Xiaomi smartphones is a procedure that can be required in a variety of situations, from replacing the battery to diagnosing hardware malfunctions, but the wrong actions can lead to damage to the board, loss of warranty or even fire. In this article, we will discuss all the current ways to turn off power on Redmi devices, POCO, Mi and other brand lines – from software methods to physical battery extraction.

It's important to understand that modern Xiaomi smartphones (especially post-2020 models) often feature non-removable batteries integrated into the case, which means that simply "remove the battery" without disassembling the device, but there are alternatives to total power out, which we'll look at in detail. If you want to replace the battery, you can't do without special tools and skills, but there are enough software solutions to reset or diagnose.

When you need to turn off the battery on Xiaomi

Before you start manipulating the battery, determine if it is really necessary. Here are typical scenarios in which users are looking for ways to turn off the power:

• 🔧 Battery replacement – if the battery is swollen, discharges quickly or does not hold charge.
• 🔄 Hard Reset – when the smartphone does not respond to buttons or freezes in the boot cycle.
• ⚡ Fault diagnosis – checking the operation of a device without a battery (for example, when connecting to a charging station).
• 🛠️ Repair or soldering of components - de-energization is mandatory when working with the motherboard.
• 🔥 Overheating or suspected short circuit – emergency shutdown to prevent damage.

If your situation doesn't make it to this list, maybe you can solve the problem with less radical methods, like forced reset (clamping the power button on the power button). 10-15 seconds) often helps with hanging, without requiring a battery shutdown, and to reset the settings to the factory just use the Recovery mode.

⚠️ Warning: Disabling the battery on a working smartphone can damage the file system.Always turn off the device before turning off the power!

Methods of disabling the battery without disassembling the device

If your goal is not to replace the battery, but simply to turn off power (for example, for reset or diagnostics), try these methods. 10/11/12, POCO X3/X4/X5, Mi 11/12/13 others.

1. Forced shutdown (Soft Power Off)

The easiest and safest way to do this is to turn off your smartphone as standard, and then wait for the battery to run out, but it can take a few days if you don't use it.

1. Activate flight mode (to turn off the communication modules that consume energy).
2. Turn on the maximum brightness of the screen and run a resource-intensive application (for example, a game).
3. Turn off battery optimization in settings: Settings → Battery → Optimizing the battery → Turn it off.

2. Discharge through the engineering menu (for advanced users)

Some Xiaomi models allow you to force the battery to discharge through hidden settings.

1. Enter the code ##4636## in the Phone app.
2. Go to the section Information about the battery.
3. Click Reset Battery Statistics (this won’t drain it completely, but will reset calibration data).

A command can be used to completely discharge ADB:

adb shell dumpsys battery set level 0

This command simulates a dead battery, but doesn't physically shut it down. Once it's rebooted, the charge level will recover.

3.Use of Recovery Mode

If your smartphone doesn’t turn off in the standard way, try Recovery Mode:

1. Turn off the device (if possible).
2. Press the power button. + Volume up on 5-10 seconds.
3. In the recovery menu, select Power Off.

This method is guaranteed to de-energize the device, but does not physically retrieve the battery.

Physical disconnection of the battery: step-by-step instructions

If you need to remove or disconnect the battery completely (for example, to replace), you will have to disassemble the smartphone, a process that requires caution and is only suitable for users with experience in electronics repair. Below is a universal guide for most Xiaomi models with a non-removable battery.

Essential tools

• 🔧 Plastic mediators (to separate the body).
• 🔨 Cross screwdriver (usually) PH00 or PH0).
• 🧲 Magnetic substrate (so as not to lose the screws).
• 🔥 Hair dryer or thermo-air station (for softening glue).
• 🧤 Antistatic bracelet (protection against static electricity).

Step-by-step disassembly process

Consider the process on the example of Xiaomi Redmi Note 10 Pro (similar to most models with a non-removable battery):

1. Turn off your smartphone and remove it. SIM-memory-card.
2. Heat the back cover with a hair dryer (temperature) ~60°C) perimeter during 1-2 minutes to soften the glue.
3. Carefully tuck the cover with a plastic mediator, starting at the bottom edge (where the charging connector is located).
4. Unscrew all the screws on the metal plate protecting the battery.
5. Disconnect the battery plume from the motherboard (use a plastic tool to avoid damaging the contacts).
6. Remove the battery by blowing it up with a mediator. Be careful - the battery is glued to the body!

On Xiaomi models after 2021 (for example, Redmi Note 11, POCO F4) The battery is often particularly glued to the body. Use isopropyl alcohol or a special glue solvent to facilitate the process.

⚠️ Note: On wireless charging models (such as the Xiaomi 13 Pro), the battery is often soldered to the board with additional contacts!

What to do if the battery is swelling

Battery bloating is one of the most dangerous malfunctions. If you notice that the back cover of a Xiaomi smartphone has become convex, the device overheats or discharges quickly, take action immediately:

Signs of battery bloating

• 📱 The body of the smartphone is deformed (the cover does not fit tightly).
• 🔥 The device overheats even in standby mode.
• ⚡ Battery discharges quickly (from 100% to 0% in a few hours).
• 🔌 Charging is interrupted or is jerking.
• 💥 The screen displays a warning “Damage Battery".

Emergency action

1. Turn off your smartphone immediately and don’t turn it on.
2. Do not connect to the charger - this can cause a fire.
3. Extract. SIM-map (if the body is still open).
4. Place the device in a non-combustible container (such as a metal container) outdoors.
5. Contact the service center to replace the battery.

Xiaomi models with a removable battery: features

If you have an old Xiaomi model (before 2016-2017), for example, Redmi 3S, Redmi 4A Or Mi Max, the battery can be removable, and then the shutdown process is simplified:

1. Turn off your smartphone.
2. Remove the back cover (usually on the latches).

If the battery is not turned on after the battery is removed, wait 5-10 minutes before re-installation. Sometimes the power controller needs time to reset.

Frequent Mistakes and How to Avoid Them

Even experienced users make mistakes when working with Xiaomi battery, here are the most common of them and ways to prevent them:

Another common problem is that the battery plume is damaged when it is not properly disconnected, and if the phone doesn't turn on after assembly, check:

• 🔌 Is the sleeve properly connected (it should fit tightly to the connector).
• 🔍 Is there any oxidation or dirt on the contacts.
• 🛠️ Are the contact legs bent on the motherboard.

💡

If after turning off the battery smartphone does not turn on, first check the connection of the plume, and do not rush to blame the battery.

How to check the battery after disconnecting

After removing or disabling the battery, it is important to make sure it is healthy and safe for later use.

1. Visual examination

Examine the battery for:

• 🔍 Bloating (even a slight bulge is a reason to replace).
• 💧 Electrolyte darts (white or green plaque on contacts).
• 🔥 Scorched areas (dark spots or meltings).
• 📉 Deformations of contacts (bent or oxidized conclusions).

2. Multimeter check

If you have a multimeter, you can measure the battery voltage:

1. Transfer the multimeter to DC (DC) mode up to 20 V.
2. Connect the probes to the extreme contacts of the battery (usually "+" and-signed).
3. Compare the readings with the nominal voltage: 🔋 3.7-4.2 B - Battery is in good working order. 🔋 3.0-3.6 V - discharged, requires charging. 🔋 Below 2.8V - deep discharge, possible loss of capacity. 🔋 0 V or jumping values - battery malfunctioning.
