Mi — phone is not charging

Address:

New Delhi, Delhi

My redmi note 4 is not charging properly
It is not charging with its original charger
And also with any other charger too
It is taking 7 hours to charge and it didn't charges when it is open
It only charges when it is switched off and not everytime
It suddenly starts charging
And it's battery is not backing up
And it didn't even completed one year till i bought it
