Hello Atul, 

Best way to study is to put your phone in silent mode while your studying. And you need to be dedicated toward study for that you should have self motivation. Take break for half an hour between your study time and reduce the use of social media for some time of period. 

Start making your own flexible target and when you achieve them than take rest for some time than start your studies. In this way you feel motivated and do not get distracted. 

All the best. Hope this will help you.
