Moto g4 plus massive battery drain

[Shantanu Deshmukh]

I own a moto g4 plus since 5 months. I have two sims in phone, one of which runs on 4G VOLTE. Battery drain on this phone is crazy. Phone never lasts more than 18 hours, including total idle time of 7 hours during night. And I never get SOT of more than 3.5 hrs. I have no clue what's going wrong. I don't play games, don't have facebook app on my mobile. Still this. It's maddening and infuriating. I always have to carry my charger around. Does anyone have any remedy for this?
