My wife and I both bought Note 8's less than 2 weeks ago. I immediately updated to Oreo; she hasn't yet. My battery life is horrible. I've been off the charger for 2 hours, and I'm down to 64%. Hers isn't great, but her phone can last all day. I've disabled background data for a lot of apps, but that doesn't seem to help.
It appears that there are a lot of other people having issues with Oreo/Note8 battery life. Do I have any options, other than returning the phone for a warranty replacement and not upgrading the new phone to Oreo?
