In this article, we will discuss all the ways to enable wireless charging on the Mi 9 (including the global and Chinese versions), explain why the device may not charge despite Qi support, and give a checklist for fault diagnosis, and learn which charging stations are compatible with the model, and how to speed up the charging process without risking the battery.

If your smartphone has been successfully charged through the air before but suddenly stopped, don't be quick to blame the hardware. 80 percent of the time, the problem is with MIUI settings, a conflict with firmware or an incompatible charger, and we tested all the scenarios and put together the working solutions.

1. Compatibility Check: Does your Xiaomi Mi 9 support wireless charging?

Before you try to enable the feature, make sure your model does have a Qi charging module. Xiaomi Mi 9 came in several versions, and not all of them support the technology:

• ✅ Standard Edition (M1902F1G) — supports wireless charging (10W standardized, up to 20W Xiaomi-branded stations).
• ✅ Transparent Edition (M1902F1T) — Full Qi compatibility, including reverse charging).
• ❌ SE Edition (M1903F2G) — simplified version without Qi module (often confused with the main model!).

To accurately determine your modification:

1. Go to Settings → About Phone → MIUI version.
2. Find the Model line (e.g. M1902F1G).
3. Check the table above.

Attention! If your smartphone is SE-version, wireless charging will not work under any circumstances - this is a hardware limitation. Attempting to modify the firmware or solder the module yourself leads to a loss of warranty and the risk of fire of the battery.

3. Why Xiaomi Mi 9 It does not charge wirelessly: top-5 cause

Even if the function is enabled, the smartphone can ignore the charging station.

• 🔄 Activate the mode of the aircraft - this speeds up charging by 25-30% (checked for the first time). MIUI 12–14).

Warning: Do not use third-party turbo modes (such as Fast Charge in custom cores) that bypass the power controller limitations, leading to battery degradation after 100-150 charge cycles.

For maximum speed, combine a wireless station with fast wired charging (Quick Charge 4+).

1. Connect your phone to the Xiaomi 20W station.
2. In parallel, connect the original Mi 9 (18W) power supply via cable.
3. MIUI will automatically distribute the load, increasing the total power to 25–27W (10W wirelessly + 17W cable).

💡

Before buying a Qi station, check its certification on the Wireless Power Consortium website. Xiaomi brand fakes often pass off as 20W, but actually give up no more than 5W.
