Update 1:
The battery lasts for 2 hours of Android Auto per day in the car, where the processor essentially works at full capacity with wireless connection, constant data usage, Bluetooth, GPS, smartwatch connected, Skype, email, and phone calls, and I barely make it home at 19:00 in the evening with 10% battery left, unfortunately. That is assuming I start using it at 08:00. Of course, all of this was a test with one charge in between, and I'm okay using it until late at night if I charge it at the office. Otherwise, it didn't overheat or freeze anywhere.

I bought it as soon as it came out, purchased it for 899 euros (unfortunately) with many gifts directly from the parent company. I can say that I could have waited another 6 months for the next model of Xiaomi since the 11T was good enough for its 2 years of use.
The phone is perfect, the camera is amazing. Night shots and everything, beautiful images. The LEICA implementation is really nice, I think I will get another 2-3 years of use with this at least, especially since Xiaomi announced long support for updates.
For now, with normal usage, constantly having 5G/Bluetooth/location connected, smartwatches, headphones, etc., using it fully from morning until midnight, I used 40% of the battery.
The fingerprint sensor under the hood is okay... satisfactory unlocking, but not as fast as when it's on the side with the power on/off button.
Of course, I will come back with updates, especially regarding the battery and the usage of Android Auto, which is a real challenge for the processor.
