The Volt (Lightning) Badge on Xiaomi Phone: 5 Reasons to Appear and How to Remove It

Why Xiaomi has a lightning or volt icon on its screen – and what to do about it

You noticed on the notification panel Xiaomi strange icon in the form of lightning, volt (⚡) Or batteries with an exclamation point -- you don't know what it means -- this symbol comes up for a reason: it signals problems with charging, battery or power. In 80% of cases, it can be removed by yourself, but sometimes it indicates serious malfunctions that require the intervention of a service center.

In this article, we will look at all the possible causes of the Volt icon on Xiaomi Redmi, POCO and Mi (including the models from 2023-2026), and give step-by-step instructions on how to eliminate it. From simple actions like changing the cable to hidden MIUI settings, you will find a solution for your situation.

⚠️ Important: If the icon flashes red or is accompanied by overheating of the phone, do not ignore the problem - this can lead to a bloating of the battery or failure of the power controller.

1.Fast charging: why the icon appears ⚡ And how to turn it off.

The most common reason is to activate the fast charging mode. Most modern Xiaomi smartphones (e.g. Redmi Note 12 Pro+, Xiaomi 13T, POCO F5) when connecting a compatible charger on the lock screen or notification panel displays a lightning icon. This is normal system behavior, not an error.

However, some users want to remove the icon — for example, if it is distracting or disturbing — in two ways:

• 🔌 Turn off fast charging in settings: go to Settings → Battery and productivity → Charging settings and deactivate the "Fast Charge" option. note that the phone will charge longer.
• 📱 Hide the icon through MIUI: In the same battery settings, find the item "Show Charging Status" and turn it off. The icon will disappear, but the charging notifications will remain in the curtain.

⚠️ Note: Some models (e.g. Xiaomi) 12S Ultra) disabling fast charging can cause battery calibration to fail. If the phone then starts to run out faster, complete a full discharge/charging cycle (0% to 100%).

2. Non-original charger or cable: how to check and what to do

If the Volt icon appeared suddenly and didn’t exist before, the problem may lie in an incompatible charger. Xiaomi smartphones are sensitive to the quality of cables and power supplies — especially models that support Quick Charge 4+ or HyperCharge (for example, Xiaomi 11T Pro or Redmi Note 11 Pro+ 5G).

How to determine what the charger is to blame:

• 🔍 Check the labeling: Xiaomi's original power supplies have a label «MDY-XX-XX» (where XX — numbers) and protocol support QC3.0/4.0. Third-party charging often fails to meet requirements.
• ⚡ Test with another cable: try charging your phone with the original USB-Type-C cable (if you use non-native cables). Cheap cables may not transmit power data, which causes the phone to show a warning.
• 📊 Power check: in battery settings (Settings) → Battery → Status) see the current charging power. If it's below 10W when you plug in a "fast" unit, the cable or charging is faulty.

💡 Tip: If you use wireless charging, the zipper icon may appear due to station incompatibility. Xiaomi recommends using only certified Qi 1.2.4-enabled devices.

3. MIUI software failures: resetting settings and firmware update

Sometimes the Volt icon appears due to firmware glitches, especially after updating MIUI or installing custom ROMs. This is typical for Android 13/14 devices (for example, Xiaomi 13 Lite, POCO X5 Pro), where the system may misrecognize the charging status.

How to fix it:

1. Sometimes a normal reboot is enough to reset the power controller's temporary errors.
2. Update MIUI. Go to Settings → About Phone → Update system and install the latest firmware. New builds often fix icon-based bugs.
3. Reset your battery settings. To do this: Settings → Applications → Application Management → Three Dots (menu) → Reset application settings → Select Battery
4. In Power + Volume Up, select Wipe Cache Partition.

⚠️ Note: If after the update MIUI The phone is slower to charge or warm up, perform battery calibration:

1. Discharge the phone before automatically shutting down.
2. Connect the original charger and charge up to 100% without interruptions.
3. Repeat the cycle 2-3 times.

4.Battery problems: how to diagnose wear

If the Volt icon appears even when charging is turned off or accompanied by a quick discharge, the problem may be a worn-out battery. Xiaomi batteries are designed for 500-800 charging cycles, after which their capacity drops by 20-30%. On models older than 2-3 years (for example, Redmi Note 9 Pro, Mi 10) this is a common reason for the appearance of warning icons.

How to check the status of the battery:

To get the exact data:

1. Enter the dialer code ##4636##.
2. Select "Battery Information".
3. Compare the figures with the table above.

💡 Useful tip: If battery capacity has dropped below 75% and the phone shuts down at 20 to 30% charge, don't delay replacing the battery.

💡

To extend the life of the battery, avoid charging to 100% and discharging below 10%.

5. Hardware malfunctions: when to carry in the service

• 🔥 The phone warms up even without load (temperature above 45).°C to the plain).
• ⚡ The volt badge flashes red or is accompanied by an audible signal.
• 🔋 The battery swelled (seen on the raised screen or warping of the body).
• 🛠️ The phone does not charge at all or only charges at a certain position of the cable.
