S20 plus battery drain

[Leroy13]

Hi there! My S20 plus is barely six months old. I don't use it much, it's my secondary phone. There are barely any apps on it and only the wifi is on, rest all is switched off. I'm still losing about 30% of battery every night even with display turned off. Kindly advise and help me out please.

It's because of exynoss processor, This device has problem since it launched, and every single device has same problem which have exynoss processor

Its not just because of the processor. 30% at night is a bit too much. Need to contact the service centre since the device is in warranty.

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.

FOR ANDROID 11;

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 Eshank
I agree to some of your points but I am not completely aligned to all of your suggestions
That is to disable almost everything then instead of doing that we will turn off mobile when not in use that gives super battery life.

Please bro with same settings enabled on other manufacturers is giving better battery life than Samsung devices now say where is the issue

[Ehsank]

Its upto you dear btw which settings bothered you and you think that is important feature among all may i know? so i will try to explain if i can

[Jeevee]

Thanks for the heads-up but Ehsank
I had already done those settings which you suggested and I am aware of all these as I don't have an option other than to do so on my s20 plus as battery is not upto the mark.
My point is I do have another mobile where Almost same settings which are suggested here to turn off are enabled and getting a better life when compared especially idle time.
And one more thing I mentioned multiple times in the community don't expect end user to have knowledge on all the settings and even if the person have knowledge also its not good experience to make ppl to thoroughly check these things and take action accordingly why we would/should someone invest so much time on checking this
