Battery
My iPhone 6 battery is dying fast when I have the screen on but when the screen is off it is not dying so fast what could that be and why can’t I use my screen so the battery won’t die

Batteries degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone.
This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.
