There are a lot of posts on this sub with vague questions, vague symptoms, a lot of missing information and bad-explained overall. I wanted to show you how to ask a good question, from an ex-Apple iOS technician.
Here's how to ask a good question:
iPhone model and iOS version
e.g. iPhone XS running iOS 13.2
2. Purchase date, country and nature of purchase
People who answer your issue can suggest certain repairs, e.g. warranty. Country and nature of purchase also helps, since countries have different consumer protection laws. For instance, members of the European Union have a two year warranty at the point of purchase (i.e. that might not be Apple, but your local electronics store if you bought it there) - some countries (e.g. the U.K. and The Netherlands) have even longer periods consumers can claim warranty.
e.g. March 20th, 2019 in the Apple Store in the U.K., purchase for personal use
3. What is the issue, how often does it occur and how to replicate it?
Some issues are continuous, some are intermittent. It is important to let people know what the issue is and how often it occurs. "iPhone restarts" as issue, is not enough.
e.g. iPhone crashes to springboard when opening the camera-app, this happens about three times a day at random moments. It only happens when opening the camera-app.
4. What caused the issue?
There's not always a clear cause, but think about anything that could've caused it. It could be because your phone was in your pocket during heavy rain, or your cat knocked it from your desk. It could be anything.
5. What did you try to resolve the issue and what was the result?
So people don't waste time answering possibilities you already tried
e.g. I tried to force-close the camera app. This did not work. Then I tried to restart the phone, that also did not work.
6. Any other information you think might be useful.
