Thank you for your support. The POCO F7 Ultra has undergone strict professional inspection before leaving the factory, so you can feel free about the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
Please use the original charger and data cable, try charging for more than 20 minutes, and press and hold the power button for 15 seconds to reset the power. This is to avoid the failure to turn on due to battery exhaustion. If it still does not turn on, please go to the after-sales for inspection and repair.
