I leave my Iphone fully charged at night and in the morning it is completely dead if I check battery usage it says siri used it 100% of the time. If I turn off my phone it does not happens for a day or two but then it comes back! I noticed it more when I don't use my phone for a few hours then siri takes over and its all gone from there on. I've called apple support a couple of time but not very much luck so far.

If Siri is off and still using 100% you really need to backup and restore as new. Restore from backup after you checked out the vanilla regime
Here is a guide for those steps:
I would disable siri until the next update.
When that comes do the update with your computer (itunes/finder) not over the air
also iphones are designed to recharge overnight. Even the best behaved phones will use 10% overnight
Thank you for that advice. I’ll try that next. Yesterday I restored the network settings only and that didn’t help.
thanks For the response, but I forgot to mention that Siri is off and also went to every single app and disabled each one of them even with Siri off and still. I hope that the next update will take care of it. I have 2 iPhones and only one does this.
