Beginner Level 2
This phone battery is draining so fast although samsung advertised it's a monster battery also i have never turned on always on display feature. 
Another major issue is that microphone is not working properly while using microsoft teams meeting app what i am saying my other team members are not able listen my voice properly and tellingme I have bad network. My 8yrs kid told me dad your previous mobile (Huwai p20) was much better than this phone because he is doing online classes and facing real problem.

and for battery as far as i know one of the main reasons of battery drain is background activity,
even you close apps but they uses ur battery and running in background unnecessary, see image(1) and read the statement.
2nd due to huge notification options.
for e.g ; Google has huge notification which we don't need at all see image(2) just scroll up and down and check how many notification it does have.
So do these settings to stop, which consume battery unnecessarily.

1. Settings>>Connection>more connections settings> disable nearby device settings

2. Settings>>Location>improve accuracy >disable
A. Wifi scanning
B. Bluetooth scanning .



Besides above settings do some more settings to save more battery life and observe for next 1-2 days, it will give a noticeable difference

3. Device care>battery >power mode>select "optimised" and "adaptive power saving".

And then click on "app power management >
And enable these 2 options.
A. Adaptive battery
B. Put Unused Apps to Sleep.


A. DEVICE CARE > Battery>Background Uses Limit > Put Unused App to Sleep

B. Device care>click on 3dot at top right corner>automation>adaptive power saving

C. Device Care > Battery> More Battery Settings>Adaptive Battery

4. Long press on each app specially 3rd party(LIKE FACEBOOK, YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info (ibutton> then go to these 3 options below on by one

A. Mobile data> allow background data usage>off

B. Battery >allow background activity >off

C. Notification >disable unnecessary notifications like promotional and unnecessary reminder notifications.

5. Go to settings> privacy > permission manager > location> and check which app have accessing your location all the time and if not using that apps then deny access or set as " allowed only while in use"
As unnecessary location access by 3rd party app causing battery drain.

6.  Go to settings > Google > on device sharing> check which 3rd party apps present there for e.g. if you use paytm , paytm will  shared data to show recommendation and suggestion which also cause battery drain

7.  Go to settings > account and backup> account > checkwhich app syncing automatically there and if any app which not necessary to auto sync then click on it and disable sync.

8. Go to settings >apps>search "weather" >click on settings icon right side > change "auto refresh" settings as per your requirements and disable some unnecessary reminder. ( due to auto refresh it continuously consuming battery)

9. If you use Facebook frequently then disable "auto play video"
And if you are mostly uses mobile, on wifi connection then also disable "auto play videos" in YouTube.

10. Settings>>Google >click on 3dot at right top corner>usage and diagnostics >off this option.
Bro, perform interactive check inside samsung memebers app get help section

Try what others said to resolve battery issues. And if microphone has issues only in Microsoft teams, then its an issue on Microsoft's side.
And for battery

change some settings like use dark mode/dark wallpaper/themes

turn off auto sync
Bluetooth/wifi when not required

Keep AOD in tap to show mode..

or drop feedback to Samsung

once perform normal phone reset settings

settings>general management>select reset>click on reset settings

for battery there are 2 things you must know.

1.actual capacity( 7000 mah)
2.rated capacity ( less than 7000 mah)

my suggestion please go and check endurance rating of the battery before buying a new device.
