Xiaomi Redmi 9 is a popular 2020 model that still holds true today due to its balanced specs and affordable price, but even with such a device, users often have questions about how to turn the phone on after buying, what to do if it does not respond to the power button, or how to avoid errors in the first setup.
The Redmi 9 features a proprietary MIUI shell that requires a binding to Xiaomi account (unless Find Device is disabled), and a non-removable 5020mAh battery, which limits how you can be forced to turn on, and we'll look at all scenarios: standard launch, activation after reset, and diagnostics if the phone doesn't turn on.
Preparation for the first launch: what to do before turning on
Before you press the power button, make sure that the basic conditions are met. Xiaomi Redmi 9 is sensitive to battery level β if it is below 5%, the system can block the start before the charger is connected. It is also important to check the configuration: the box must have a USB Type-C cable and a 10W power supply (or 18W in some regions).
If you bought your phone with your hands, you should:
- π Make sure the battery doesn't blow (look at the warping of the back cover).
- π Check the health of the Type-C port β connect the charging and see if the indicator appears.
- π± Examine the screen for the presence of "broken" pixels (turn on the flashlight and illuminate the display turned off).
- π Ask the previous owner to unplug the Mi Account if the phone was in use.
If the phone was stored in cold or high humidity, give it 1-2 hours to acclimatize at room temperature. Condensation inside the case can cause a short circuit when connected to a charge.

If you buy a Redmi 9 b/d, ask the seller to make a factory reset (Settings β About Phone β Settings Reset) with you.

- Wait for MIUI to load. The first launch can take up to 2-3 minutes, which is normal.

- π± Transfer data from your old phone (via cable or cloud).

If the phone requires a password from the previous Mi Account when it is first turned on, it means that the device was not reset correctly, in which case you will need to contact the seller or use the official Xiaomi service to unlock.
