J7 pro released in 2017 so its almost 3 years old. So the lithium ion battery may have loosed its capacity.The charge Depending on Battery mah it may have around 300-500 or may be even more charge Cycles i.e) 0-100% is 1 cycle. if charged from around 50-100 % it may be consider as 1/2 cycle.So from that you may approximately calculate the number of times you have charge the phone.Overuse and charge-dischrage phone frequently/continously may effect battery life.
