Calendar draining battery iPhone 7 plus

[chrisduk]

Hi guys

I’m getting around 5 hours usage on my iPhone 7 Plus. The calendar background tasks is draining the battery, it does sometimes say Apple Watch is the cause. I’ve tried disabling calendar stuff on the watch app and also reset watch and reinstalled everything.

iPhone 7 Plus latest dev beta
Apple Watch series 2 also latest dev beta

I have logged bugs in the app on iPhone but never heard back from Apple.

Does anyone know how to fix?

I haven’t noticed battery life being an issue with the betas on my 7+
