lg g4 battery charged notification.. it repeatedly keeps beeping/ vibrating

[Lizmo623]

Ive had my g4 for about a month and a half... Charge it a few times a week at night, last week it woke me up at 4am telling me it was fully charged... By vibrating and beeping repeatedly. I set up my down time between 1am and 7am for no notifications and it still wakes me up. Any ideas on why this is happeneing and mainly how to stop it? Thanks in advance
