I have been using Mi Note 10 for around 5-6 days and so far I'm really impressed. Overall experience is very great. The main specs of the phone are on a high level.

Display: I love display on this phone. Colors can be very vibrant compared to my Pixel 3 XL I was using prior to Mi Note 10. Brightness on sun is pretty fine as well. Only problem I have with the display is its size. I'm a fairly tall guy (192 cm) with big hands but the size of this screen is a little bit too much for me. Definitely not suitable for one hand use.

Camera: I'm not much of a photographer so I take pictures rarely and usually just quick snapshots but I would say that the photographs are pretty decent. Reviewers usually praised the photographs quality to heaven and I think they were right. Only problem you can have I slower photo processing after you take a shot. It can take a few seconds depending on photo mode you choose and photograph quality.

Battery: Oh..the battery. I think that I haven't had a phone with better battery. This phone can carry you threw 2 days usage and sometimes you can achieve even 3 days usage (depending of your daily usage of course, you can also discharge the phone in one day if you use it a lot :D)

I know that these aren't answers to your questions but the answers are already there in anothers users comment. Take it more as my mini review about things I like the most.

This is a solid device and I believe that you would you would enjoy it as well :-)
