Wireless charging on Xiaomi Redmi 9T: how to turn on and configure

Is there a wireless charging system in the Redmi 9T?

Xiaomi Redmi 9T (codenamed lime) has become one of the brand’s most popular budget phones due to its balanced performance and long battery life. However, many users are wondering whether this model supports wireless charging according to the Qi standard.

Officially, the Redmi 9T’s technical specifications (like most Xiaomi budget smartphones) don’t specify wireless charging, but some owners claim they managed to charge the device without wires — but with reservations.The Redmi 9T’s case doesn’t have a built-in Qi coil, but its battery is theoretically capable of taking current from an external wireless module if it’s connected correctly.

In this article, we will discuss:

• 🔍 How to check the compatibility of your Redmi 9T wirelessly charged
• ⚡ Step-by-step instructions for connecting an external Qi module (if supported)
• ⚠️ Possible risks and why the manufacturer did not add the feature out of the box"
• 🛠️ Alternative methods of wireless charging for non-removable batteries

Compatibility Check: Does your Redmi support 9T Qi charging?

Before you try to turn on wireless charging, you need to know if your smartphone has the technical ability to support it. The Redmi 9T (like the Redmi 9 Power, which is its counterpart in India) does not have a built-in Qi coil, as confirmed by:

• 📄 Official documentation of Xiaomi (specifications on the manufacturer's website)
• 🔧 Device disassembly on YouTube (e.g. PBKreviews channel)
• 📊 Tests using Qi-charging (smartphone does not respond to placement on the charging pad)

But there's a caveat: some users are successfully using external Qi modules connected to a USB-C connector. These modules simulate wired charging, but allow you to place the smartphone on a wireless platform. It's important to understand that this is not a real wireless charging, but rather an adapter with a transition to a wired protocol.

⚠️ Note: External Qi modules may cause the battery to overheat or decrease its life. Xiaomi does not guarantee stable operation in such conditions.

Step-by-step: how to connect wireless charging to Redmi 9T

If you're willing to experiment, here's a step-by-step algorithm for connecting wireless charging through an external module.

• 🛒 Qi-receiver with connector USB-C (Nillkin Magic Disk and Baseus Wireless Charger Receiver)
• 🔌 Wireless charging pad (with a power not exceeding 10 W)
• 📱 Smartphone with unlocked bootloader (optional, for some modules)

Step 1: Preparing the smartphone

Make sure that:

Battery level – at least 30%|All background applications disabled|Removed cover (more than 3 mm thick)|Port port USB-C clean (no dust/garbage)-->

Step 2: Connecting the Qi module

1. Carefully insert the Qi receiver into the USB-C connector of the smartphone, it should fit tightly, but not bend the body.
2. Place your smartphone on the charging pad so that the module coil matches the center of the site (usually marked with a logo).
3. Wait for the charging icon to appear on the screen. If there is no indication, try to shift the smartphone by 1-2 mm.

Step 3: Stability check

After successful connection:

• 🔋 Check the body temperature in 10 minutes (normal - up to 40).°C).
• ⚡ Make sure the charging power doesn’t drop (use the Ampere app to monitor your charging power).
• 📉 Keep track of charge percentage for an hour – if the growth is less than 10%, the module is inefficient.

💡

If the smartphone is not charging, try turning the Qi module upside down – sometimes the coils match only in one position.

Why wireless charging might not work on the Redmi 9T

Even with the right Qi module connection, the charging may not start, and here are the main reasons and ways to eliminate them:

If neither of these methods worked, your Redmi 9T may have a hardware constraint at the power controller level, leaving you with two options:

1. Use magnetic charging (e.g. MagSafe-compatible adapters).
2. Upgrade your smartphone to a model with built-in Qi charging (for example, Xiaomi 13 or POCO F4 GT).

Alternative ways to charge wirelessly for Redmi 9T

If a standard Qi module is not suitable, consider alternative solutions:

• 🧲 Magnetic Chargers (e.g. Anker 622): attached to the back and connected to the back USB-C. Cons – require accurate positioning.
• ☀️ Solar power banks with wireless output: suitable for hiking, but slowly charge (1-3 watts).
• 🔄 Reverse wireless charging (from another smartphone): if you have a device with Reverse Wireless Charging (like Samsung Galaxy) S21+), You can try charging Redmi. 9T "phone-to-phone".

The most reliable, but time-consuming way is to install a built-in Qi module by disassembling a smartphone.

• ⚠️ It is not guaranteed (if it is still valid).
• 🔧 Requires soldering skills (you need to connect the coil to the power board).
• 💸 It is more expensive to buy a new smartphone with support for Qi.

⚠️ Attention: When disassembling Redmi 9T There's a high risk of damage to the battery plume or the display cable. If you're not sure about your skills, contact the service center.

How to Care for a Battery When Using Wireless Charging

Wireless charging (even through an adapter) loads the battery harder than wired charging, to extend the battery life:

Do not charge for more than 2 hours in a row|Remove the cover while charging.|Use the ventilator area|Do not charge at a temperature below 10°C or higher than 35°C-->

Optimal charging mode:

• 🔋 Keep the charge at 20-80% (avoid full discharge and 100% charge).
• ⏱️ Charge short sessions (30-40 minutes) instead of long sessions.
• 🌡️ Watch the temperature: if the body is hot, interrupt the charging.

To monitor the status of the battery, use the applications:

• AccuBattery (shows wear and temperature).
• Ampere (tracks the charging current).
• CPU-Z (checks the battery voltage).

💡

Wireless charging via an adapter is a trade-off between convenience and security, and for regular use, it’s best to choose a smartphone with built-in Qi support.
