If you guys are having battery issues, try out the following:
1) Use dark mode (OLED screens do not use battery when displaying black, and use the most power to display white). The screen is usually the most power hungry component on the entire device. Also use auto-brightness.
2) Go into the individual app settings and disable background data usage for problematic apps that love to keep your phone awake such as social media, weather, news, etc. If it updates when you open the app instead, usually that is just as good and does not affect usage. Some apps constantly check things like your location as well.
3) Go into the individual app settings and set background data usage to "Restricted" for those same apps, or anything that doesn't need to be running as a background process while you sleep or whatever.
4) Don't let the phone constantly scan for and alert you of nearby WiFi networks
5) Don't let the phone wake up it's entire screen when you get a notification, and disable the always-on display if you don't need it (personally I use double tap to wake/sleep along with brief notifications).
6) Disable the "always listening" (Hey Google) for Google assistant unless you need that
7) If you really want to get into it, use Bixby routines to set some schedules (if you aren't familiar with it, they are basically powerful if/then statements) to control things that use battery life. For example, you can tell it to put the phone in battery saving mode if it's past 11pm and your phone isn't charging, and disable at 7am. There are unlimited options there. Bixby routines is actually extremely powerful.
8) If you get tons of notifications overnight, leave your phone on silent or DND rather than vibrate
And more broadly, treat your battery well and it will stay close to maximum capacity for much longer if you aren't someone who gets a new phone every year. Never leave it charging overnight (especially if you let it charge to 100% and don't use the 85% "battery saver" function). Don't let it sit at 100% charge for long periods of time. Don't run it down to 0% or really close to 0% on a regular basis, especially if it's cold. Don't let it sit somewhere extremely hot or cold for any extended period if time. Don't fast-charge it unless you need to (heat degrades lithium batteries faster).
I lose 1-3% over an ~8 hour sleep, exactly the same as my iPhone.
