I have the Snap Dragon S8+ with T-Mobile.
I have auto brightness on, with optimized performance mode on. I have Wi-Fi, Bluetooth, GPS enabled, always on display is also on. I have not shut any apps off except lookout security. I have adguard also. If I can answer anymore questions, let me know.
Best battery life I've ever had on a phone.
