My parents looked at my texts! How do i report them?

I live in america and my parents got me an iphone x for christmas and i got in trouble at school for harassing this girl and when i got home my parents wanted to see my texts and i refused and they said they will take my phone for a day if i don't let them see so i screamed at them to **** off and they tried to grab it so i hit my mom and ran away and tripped and smashed my
phone on the floor and it cracked. I want to report my parents i'm really mad because that phone was so expensive and THEY ******* BROKE IT THEIR SITS STUPID FFS. They offered to get me a new iphone x but i'm still really upset and want to get them in trouble with the cops so they don't do something like that again

How can i know if my phone is being eavesdroped on through the cellular network?

Friend of an ex-friend can do this. I think they have been doing it to me. This person's career is bank security. Allegedly, he can tap into any phone and pull anything off it remotley without needing to use any malware or having physical access to the phone. What can i do to my iphone SE, if i can't block the eavesdropping, to just know when it is going on?

Added (1). he can also activate the cameras and microphones and gps track with the phone. I don't like this happening to me. How can i stop it?

Is it normal for iPhone battery sensor to be thrown off during cold weather?

I was using my iPhone outside for directions and it was 80 percent battery life. It was 20 degrees and windy. After being exposed for about 10 minutes in the cold, my phone showed 10 percent battery and then shut off and wouldn't turn on. I finally walked into a heated room and my phone finally turned on and went back to 80 percent battery. Is this normal or does my phone need to be checked?
