Game is too fast in Mobile

For some reason, the game gets REALLY FAST when i play it in my cellphone, Some people say that i need to use Time.deltaTime. BUT I’M USING IT!!! In my game, the player keeps moving. That’s the line where is it:
GetComponent.().velocity.z = 800*Time.deltaTime;
In the computer, it is soft and pretty.
Please help me guys!! I need to upload the game!!!

Good day.

I dont know why is that fast, but you can change the time scale for each platform. When is 0 time stops, when is 1, times goes normal. Yo ucan try with:

Time.timeScale = 0.75f;
