Xiaomi Mi 9T Pro Specifications

Hello and thank you for your efforts. In my opinion, my worst experience was with Xiaomi. If I could go back, I wouldn't want to get this phone again. In the phone settings, it says the battery is great, but the battery quickly drops to 60% and then to 10% and shuts down. It was supposed to be a flagship at its time. I have sent several messages to the company from within the phone, but there is no response. At least a battery update should be sent.
