"నేను నిన్ను ప్రేమిస్తున్నాను" (pronounced as "Nenu ninnu premistunnanu").
This is the standard way to express "I love you" in Telugu, which is commonly understood and used in Hyderabad, the capital city of the Indian state of Telangana. However, it's important to note that Hyderabad is a diverse city, and many other languages and dialects are spoken there, including Hindi, Urdu, and English. So, depending on the person and the context, the expression may vary. But in Telugu, "Nenu ninnu premistunnanu" is the phrase you can use to say "I love you."
