Granted I have a lot of programs open all the time and get a lot of alerts, but this never effected ios 10.

Apple released ios 11.1 today and I quickly upgraded the phone again. It was reported that the 11.1 update would correct for the battery problems, so there wasn't really a choice for me. So far I havent noticed a change between 11.03 and 11.1 but I have only been running 11.1 for a few hours.

For reference, I was always able to make it through a day of heavy use with iOS 10. I was never nervous that I was going to drop a call or run out of battery before the day was over. When I upgraded to ios 11, I was/am very concerned. I had to do a lot of battery saving things like decrease the brightness immediately and monitor background apps closely.
It will take a day or two for the phone to finish indexing before you'd notice any improvements.
