I have bought Galaxy A15. I am facing serious problem of battery drainge. Its battery drop down from 100 to 50 percent in just two hours.

 And then from 50 to 20 in just 45 minutes. 

 But the major problem is even if i did not use it whole it drop down from 100 to 50 at the end of day. Could anybody pls help me to resolve the issue.
