Introduction: Myths and Realities About Wireless Charging in Redmi Note 7
Since the release of the Xiaomi Redmi Note 7 in 2019, users have been actively discussing its capabilities, especially the issue of supporting wireless charging. Many smartphone owners mistakenly believe that the model is equipped with Qi technology, since competitors (for example, the Samsung Galaxy S10 or iPhone 8) already offered it in the same price segment. However, the reality is much more prosaic: the manufacturer deliberately excluded this feature from the budget lineup, focusing on other advantages, such as a 48-megapixel camera or a glass case Gorilla Glass 5.
In this article, we’ll look at 5 reliable ways to check whether your Redmi Note 7 supports wireless charging, from analyzing official documentation to practical tests using chargers, and why even with Qi modules in some smartphone versions, its activation can be blocked at the software level, and what alternative solutions exist for owners of this model.
1.Official specs: What Xiaomi says
The most reliable source of information is the specifications published by the manufacturer. Xiaomi’s website in the Redmi Note 7 section clearly states that the model supports only wired charging with a power of up to 18 watts (Quick Charge 4.0). Wireless charging Qi is not on the list – nor in the global version (MIUI Global, neither in Chinese (MIUI China).
However, there is a caveat: some regional modifications (such as the Redmi Note 7 Pro for India) may have received hardware updates. To avoid confusion, check the exact model of your device in the settings:
- Open the Settings. → The phone.
- Find the Model and Model Number lines.
- Compare the data with the official table below.
| Model | Device code | Support for Qi | Note |
|---|---|---|---|
| Redmi Note 7 | lavender | ❌ No. | All versions including Global and China |
| Redmi Note 7 Pro | violett | ❌ No. | Even with the Snapdragon 675 processor |
| Redmi Note 7S | lavender_spr | ❌ No. | Modification for India |
⚠️ Note: On some marketplaces (such as AliExpress or eBay), sellers indicate in the description "Qi support" for the Redmi Note 7. This is either an error or a fraud - the original firmware feature is missing.
2. Visual inspection: where to look for signs of a Qi module
If you don't trust the documentation or you've bought your phone with your hands, check the body and the internal components. Wireless charging requires a special coil under the back cover.
- 🔍 Back cover: Qi devices often have a barely visible coil outline under the glass (especially if you shine a flashlight). The Redmi Note 7 doesn't have one - instead, you'll see only antenna mounts. NFC (If the model supports contactless payment).
- 🛠️ Disassembly: When removing the lid (not recommended without experience!), look for a flat spiral board next to the battery. In the Redmi Note 7, its place is taken by a metal plate for cooling the processor.
- 📏 The Qi module increases the thickness of the smartphone by 0.3-0.5 mm. Compare your phone to the reference dimensions: Redmi Note 7 has a thickness of 8.1 mm – as well as models without wireless charging.
What to do if you find a suspicious fee?
⚠️ Warning: Disassembly of the smartphone will void the warranty Xiaomi.If you are not sure of your skills, contact the service center - the masters will check the presence of the module without risk of damage.
3. Practical test: how to check the charging without disassembly
The easiest way to charge your phone is to try using a Qi certified charger (such as Samsung or Anker).
1. Use a charging station with a power of at least 5 W
2.Make sure the phone has a cover (especially metal) removed.
3. Connect the charging to the socket and wait for the indication of readiness
4. Place the phone in the center of the court (coaxial with coil)
-->
- Position: Place the Redmi Note 7 on the charging pad with a screen upwards, so the coil (if any) will be closer to the power source.
- Indication: The screen should display a “Wireless Charging” notification or a battery icon with the Qi symbol. In Redmi Note 7, this will never happen – instead, you will see a message “No Charging supported”.
- Temperature check: In 2-3 minutes, touch the back cover. When you charge Qi, it warms slightly. In the case of the Redmi Note 7, the temperature will remain unchanged.
If the phone doesn’t respond, try restarting it and repeating the test. Also make sure the charging station is working – check it on another device (such as an iPhone or Galaxy).

4. Software diagnostics: hidden settings and applications
In some cases, information about Qi support can be found in the Android service menu or using specialized utilities.
- 📱 Code ##4636##: Enter it in the Phone app, then go to Battery Information. Supported devices may display Wireless charging: supported. Redmi Note 7 does not have this line.
- 🔧 Annex AIDA64: Install it from Google Play, then open the Battery section. Scroll down — if you have Qi support, you will see a Wireless charging item with Yes status.
⚠️ Note: Some "optimized" firmware (e.g, MIUI EU Or custom builds) can display false data, and if you're using unofficial software, the software diagnostics results are unreliable.
💡
If AIDA64 displays an unknown module with the name NXP PN547 — it NFC-chip, not Qi. Don't confuse them!
5. Alternative solutions: how to add wireless charging
If your Redmi Note 7 doesn’t support Qi, but you need this feature, consider the following options:
- 🔌 Connector adapters USB-C: There are adapters (e.g. Yootech Wireless Charger Receiver) that connect to the phone port and allow you to charge at a Qi station.
| Decision | Cost (≈) | Pluses | Cons |
|---|---|---|---|
| USB-C adapter → Qi | 500–1200 ₽ | No need to disassemble, compatible with any Qi-stations | Locks the port, slow charging (5 watts) |
| Case with Qi | 1500–3000 ₽ | Protects the phone, built-in battery | Increases thickness, not all models fit |
| Self-installation of the module | 2000–5000 ₽ | Full Qi charging at 10W | Difficulty, risk of damage, loss of warranty |
⚠️ Note: When using adapters USB-C → Qi avoid cheap models without certification. They can overheat and damage the charging port. The best choice is Quick Charge adapters and surge protection.
6. Frequent Mistakes and Myths About Wireless Charging in Redmi Note 7
There are a few misconceptions that are common on the Internet that are misleading users, and we'll look at the most popular ones.
- 🔄 "After updating MIUI It's going to be Qi: It's not possible. Wireless charging requires hardware that you can't add software to. Firmware updates can only improve the management of existing components.
- 📡 "NFC = wireless charging": NFC And Qi is different technologies, one is used for contactless payments, the other is used for power transmission. NFC Redmi Note 7 (in some versions) does not support charging.
- 🔋 "If the phone is warming up on a charge, it means Qi is working": "Heating can be caused by induction tips from the station coil, but this does not mean that energy is transferred to the battery.
Another common myth is that the Redmi Note 7 Pro supports Qi thanks to a more powerful processor. In fact, both devices (Note 7 and Note 7 Pro) are built on the same hardware platform and do not have Differences in the charging system.
💡
Wireless charging is a physical module, not a software feature, and no updates, root rights, or “secret settings” can add it to the Redmi Note 7 if it’s not in the phone’s design.
