How to check wireless charging support on Xiaomi Redmi 9: all ways

Xiaomi Redmi 9 is one of the most popular budget smartphones of the brand, but its specifications often raise questions among users. Especially relevant is the question of wireless charging: whether the model supports the Qi standard, whether you can use charging stations, and what to do if the feature is not in the basic configuration. In this article, we will analyze all official and informal methods of verification, and also tell you how to circumvent restrictions, if any.

Note that the support for wireless charging in Redmi 9 is controversial. The manufacturer does not always clearly specify this feature in the specifications, and users face different results in testing. We have collected all the current data for 2026, including checking through settings, visual inspection, tests with chargers and even disassembly of the case (for power users), and you will learn what alternative solutions exist for models without built-in Qi support.

1. Official specs: What Xiaomi says

The first and most reliable way is to look at the manufacturer’s technical documentation, but Redmi 9 users are disappointed: on Xiaomi’s official website, in the Redmi 9 (2020) specification section, wireless charging is not listed in the list of supported features.

• 📱 Redmi 9 (codenamed Lancelot) - basic version;
• 📱 Redmi 9 Prime (Indian version);
• 📱 Redmi 9C/9A — simplified;
• 📱 Redmi 9T/9 Power - versions with an increased battery.

However, there are claims that some Redmi 9 batches (especially those sold in China) were equipped with a Qi module. This is unlikely, since even Xiaomi’s flagship models of the period (such as the Mi 10) did not have wireless charging as standard. The only exception is special editions for individual regions, but they were marked differently (for example, the Redmi 9 Pro 5G).

To avoid confusion, check the exact model of your device:

1. Open the settings → About the phone → Model.
2. Compare the code name with official documentation (e.g. M2004J19C for global version of Redmi 9).

2. Visual signs: what to look for on the body and in the configuration

If the official data is not clear, check the case and its configuration. wireless charging Qi requires a special receiver module under the back cover.

• 🔍 Qi logo – original wireless charging devices often have a standard icon (a stylized letter “Q”) on the back or next to the connector USB-C.
• 📦 Charger included - if there was a wireless station in the box, it's 100% confirmation.However, Redmi 9 only comes with a wired adapter.
• 🛠️ Rear material – glass or metallized plastic can block the Qi signal. Redmi 9 uses plastic, which theoretically does not interfere with the module, but it simply does not exist.

Important: Some vendors stick stickers with the Qi logo on phones without feature support. To avoid cheating, check the device with a hands-on test (more on this in the next section).

Another indirect sign is the thickness of the case. The wireless charging module adds ~0.5-1 mm to the dimensions. Compare your Redmi 9 (9.1 mm thick) with models where Qi is exactly there (for example, Xiaomi Mi 9 - 7.6 mm without the module vs Mi 9 Pro - 8.5 mm with the module).

3. Practical test: how to check charging without documentation

The most reliable method is to connect your smartphone to a wireless station.

• ⚡ Qi standard charging station (power 5-10 W);
• 📱 Smartphone with a charge level below 80% (for clear indication);
• 🔌 Cable USB-C (for comparison with wired charging).

Instructions for testing:

Make sure the station is connected to the network.|Put the phone in the center of the platform.|Wait 10-15 seconds.|Check the charging indication on the screen|Compare speed with wired method-->

What's going to happen:

1. The screen will show a wireless charging icon (a stylized spiral or lightning without a cable).
2. The status bar will display the inscription "Charging (wireless)".
3. The temperature of the back panel will rise slightly (but not critically).

If nothing happens,

• ❌ The phone doesn't support Qi.
• ❌ The station is faulty or not powerful enough (try another device).
• ❌ The case is too thick (remove it and repeat the test).

💡

Use a station with Fast Charge support (e.g. Xiaomi Mi Wireless Charging Pad 20W). Even if the phone doesn't support wireless charging, some stations may show a false positive due to the heating of the coil.

4. Software Methods: Verification through Settings and Applications

If the physical test failed, check the Qi support program.

1. Go to Settings. → Battery.
2. Look for items like "Wireless Charging" or "Qi Compatibility." Redmi 9 doesn't have them.
3. Open Settings → Additional → Special features → Physical buttons (sometimes there are hidden options for wireless accessories).

You can also use the application side for diagnosis:

In AIDA64, go to Battery and look for the lines "Wireless charging" or "Qi standard." In CPU-Z, check the Battery tab - if there is support, it will indicate the maximum wireless charging power (for example, "5W (Qi)").

⚠️ Note: Some apps may show false data if the phone is modified (for example, stitched with custom software.

5. disassembly of the case: the last method for experienced users

If you're willing to take drastic measures, you can take your phone apart and check for a Qi receiver coil. This method is only suitable for users with experience in electronics repair!

What you'll need:

• 🔧 Set of screwdrivers (cross, flat, plastic shoulder blades);
• 🧲 Screen suction cup;
• 🔥 Fryer (for softening glue);
• 📸 Camera (to capture the location of the parts).

Step-by-step:

1. Turn off the phone and remove it. SIM-map.
2. Heat the screen edge with a hair dryer (~60°C) for 2-3 minutes.
3. Carefully tuck the screen with a plastic spatula, starting from the lower corner.
4. Disconnect the battery plumes and the display (use a screwdriver with an insulated handle!).
5. Look for a flat spiral coil under the back cover (usually next to the battery). Redmi 9 doesn't have one.

⚠️ Warning: Disassembly will void warranty and may damage plumes or batteries. If you are not sure about your skills, contact the service center.

If the coil is missing, but you want to add Qi support, you can install an external receiver module (like the Nillkin Magic Tag) that glues under the case and connects to the USB-C connector, but requires constant wearing of the case and reduces the charging speed to 5 watts.

6. Alternative solutions: what to do if there is no wireless charging

If tests have confirmed that Qi is not present in your Redmi 9, don’t be discouraged. There are several ways to get around this limitation:

• 🔌 Connector adapters USB-C — Devices like the Baseus Wireless Charger Receiver connect to the port and allow you to use any Qi station.
• 📱 Cases with built-in battery, such as the Xiaomi Mi Power Bank Case, support wireless charging while increasing battery capacity.
• ⚡ Modification of the case - in some services, a Qi coil is installed under the back cover (cost) ~1500-2,000 rubles. Risky, but it works.

Also, look for magnetic charging cables (such as MagSafe-compatible ones) that don’t provide full wireless charging, but make it easier to connect and reduce connector wear.

💡

The most reliable and secure option is an adapter with a USB-C connector. It does not require any interference with the design of the phone and is compatible with most Qi stations.

7. Frequent Mistakes and Myths About Wireless Charging in Redmi 9

There are a few misconceptions that are common online that are misleading users, and we'll look at the most popular ones.

Another myth is that wireless charging spoils the battery faster. In fact, modern Qi controllers (even in low-cost stations) regulate current and voltage to minimize wear, the main thing is to use certified devices (for example, with the Qi Certified logo).

If you encounter a vendor who claims Redmi 9 supports Qi, ask:

1. Show a certificate of conformity to the Qi standard (for a batch of phones).
2. Do the test at the charging station with you.
3. Show disassembly of the phone (if sold as "used with modification").
