Does Xiaomi Redmi 9 support wireless charging? Full list of compatible models and alternative solutions

Wireless charging has become an integral part of modern smartphones, but not all Xiaomi Redmi models come with this out-of-the-box feature.The Redmi 9 is one of the brand's most popular budget lines, and the issue of Qi standard support worries many users. In this article, we will see if you can charge Redmi 9, Redmi 9A, Redmi 9C redmi 9T Wireless, what official and informal solutions exist, and also provide a list of all Xiaomi models that support wireless charging.

It’s worth clarifying right away that all Redmi 9 models (including Pro, Prime, Activ) don’t have a wireless charging coil built in, but that doesn’t mean that owners of these devices will have to accept wired charging. There are workarounds — from adapters to body modifications — that we’ll take a closer look at. In addition, we’ll analyze which flagship and mid-budget Xiaomi smartphones initially support Qi so you can compare the capabilities of different lines.

The official support for wireless charging in Redmi 9: myth or reality?

If you look at the specifications of Xiaomi Redmi 9 on the official website or in the documentation, you will not find mention of the Qi standard. This is not surprising: wireless charging is traditionally considered a “premium” feature, and the Redmi 9 series is positioned as a budget solution. Even more advanced versions — Redmi 9 Pro or Redmi 9 Power — are not equipped with this technology.

The reason lies in the design features: to implement Qi requires:

• 🔋 Integrated induction charging coil (not found in Redmi 9)
• 📱 Special glass or plastic back covering (metal housings block the signal)
• 🔌 Support for the protocol at the firmware level (in budget models often missing)

However, some users claim they managed to charge the Redmi 9 wirelessly with third-party accessories. How is that possible?

Alternative ways to charge wirelessly for Redmi 9

While Redmi 9 doesn’t support Qi at the hardware level, there are a few ways to get around this limitation. Let’s take a closer look at them, including the pros and cons of each method.

1. Connector adapters USB-C

The simplest solution is to use a wireless charging receiver that connects to the port. USB-C. This adapter is a small plate with a coil that is attached to the back of the smartphone:

• 🔌 The adapter connects to the connector. USB-C phone
• 📶 Apply your smartphone to the Qi charging station
• ⚡ Energy is transferred through the adapter to the battery

Advantages:

✅ No need to take down the phone.

✅ Compatible with any Qi charging station

✅ Price from 300-800 rubles

Disadvantages:

❌ Increases the thickness of the phone

❌ May interfere with the use of covers

❌ Charging speed is lower than that of wired solutions (usually up to the current level). 5W)

💡

Before buying an adapter, check if it supports Quick Charge. 5W, This is much slower than the standard wired charging of the Redmi 9 (18W).

2. Modification of the case (for experienced users)

A more radical way is to install a coil of wireless charging inside the case, which requires disassembling the phone and is only suitable for those with experience in electronics repair.

• 🛠️ Coil Qi (can be soldered from an old smartphone)
• 🔧 Stolen iron and solder
• 📱 Disassembly of the back cover (risk of damage to plumes!)

⚠️ Note: This modification deprives of warranty and may lead to:

⚠️ Warning: Battery damage if the coil is not connected correctly. There may also be problems with overheating, as Redmi 9 does not have a cooling system designed for wireless charging.

If you still decide to take this step, we recommend using a coil from Xiaomi Mi 9 or Redmi Note 8 Pro - they are compatible in size. 7.5W.

3. cases with wireless charging

Some accessories manufacturers have cases with a built-in coil, and the way it works is similar to adapters, but it looks more aesthetic.

• 🔋 Spigen Wireless Charging (compatible with Qi)

Pros:

✅ It retains the original design of the phone.

✅ Protects the body from scratches

Cons:

❌ More expensive adapters (from 1500 rubles)

❌ Could degrade the signal. NFC (If you have it in your model)

Compatibility with USB-C (not micro-USB!)

Maximum charging power (optimum) 7.5W–10W)

Magnetic attachment (so that the adapter does not move)
