Moto G4 plus battery drain rate increased after nougat.

[AC Question]

Brothers, on marshmallow, while using music, whatsapp, messenger & occasional browsing for an hour my battery would lose 13-14% charge. A week ago i updated to nougat. And now my battery drains 16% in 58 minutes while using messenger & whatsapp only. And moreover after 30%, on marshmallow, battery drain rate was 1% in 3-4 minutes. Now it is 1% per 2 minutes.
