I ve just bought a new Iphone Xr and i want to buy an magnetic case for it. As i informed from others, that magnetic filed may affect signal and also it may damage the screen display over time. Is that correct?
My second quest. is that as far as i know Iphone xr supports quick charge and wireless charge. I also informed that those chargers may affect the battery life. Is that correct?

iPhone XR, iOS 12
You have been sadly misinformed. A magnetic case will have no impact whatsoever on the display or other functions of the phone, except it might confuse the Compass app.
As far as fast charging goes, Apple has approved it with the correct accessories so it should not damage or degrade the device. However, uncontrolled fast charging to maximum would probably make the battery warm more than slow charge so the total capacity might be reduced on that one charge cycle. That is why Apple designed quick charge to reduce to slow charge for the last part of charging, to allow the battery to cool before it reaches maximum capacity. Wireless charging is generally slow rate anyway so it should not cause problems - once again, providing you use approved accessories.

I know nothing about the magnetic charge, hope someone will show up and clarify that for you.
But speaking of wireless charging and fast charging – it's a lie. You can use them with no fear. iOS is pretty smart and it takes as much as it needs to charge an iPhone and if the overheating happens, then it disable the charge. To improve the cooling during the wireless charging or fast charging Apple recommends to take off the iPhone's case.
A magnetic case may not work with a wireless charger - the case I tried with my iPhone 8 interfered with the wireless charger I'd purchased.
I ended up getting a different case due to some manufacturing defects in my first one. No magnet in this case and wireless charging works as expected.
