For those not reading the other thread here are my first impressions:
So first REAL stress test here. I travel for work and today had a 12h day on the road, through areas with low to bad signal, but also cities with LTE (no 5G contract atm). I did a call a few times and did some surfing. The usual stuff I also did with my iPhone 11 6.1 before.
At the end of the day I have about 40% battery left, when my iPhone 11 had around 50-60% battery left with similar usage. That is more than I expected. I had signal on all the time and battery life really suffers from traveling through low signal areas instead of staying at home in the city with always good LTE signal. I am very happy. I expected around 20-25% left at the end of the day but it is around 40%. 10-20% less than the iPhone 11. And the battery is new and still needs some time for it's whole potential. Really, really nice atm.
Reception is much better than my iPhone 11 when it comes to holding a signal and using internet in low signal areas. The signal was most of the time displayed similar to my iPhone 11. But I never had much of those no service zones ever with my iPhone 11 thank god so no big change here. But when my 11 couldn't connect to the internet with 2G or 3G reception, my 12 Mini could. I had 4 bars 2G Edge and could load light webpages. The 11 didn't do that or it took way longer to load. Nice!
Call quality is ok, nothing special, but good enough. Had trouble with one call dropped after going from LTE to 3g, but otherwise good but normal call quality.
The device itself on the road is really, really nice. Typing with one hand without a problem, not needing to balance the phone just right to get to the top and not let it slip out of the hand... Very nice. I just have to get used to the small display mode. The larger one is just too large for normal usage. The standard display mode a little too small.
First impressions are very good. Now if they could only do a SW update that fixes those issues with black pixels not turning off. Then it would be amazing.
PS: Did use the phone caseless for 2 days, just feels so much nicer, thinner, narrower, lighter. Perfect!
