Samsung M31s battery life

[DevVora12]

I bought a Samsung m31s at end of August 2020. Since I bought the phone, I think I am starting to notice that it's battery life is not living up to its mark. 

I usually use my phone to access discord, Twitter, Clash Royale, Youtube, WhatsApp, Instagram and Spotify(other apps too, but these apps I use daily). Other then this, my usage of the phone is not heavy. It's charging time varies from 90 mins to 120 mins. 

Sometimes I have noticed that the screen freezes when I lock the Phone while using an app. Then I have to press the home button. Only then I can again use the phone. 

Many a time my fingerprint isn't recognised. Though this may be because of me.  

Is there any problem with the device? 

Are there ways to find out if something is wrong with the device?

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

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

2. 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

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

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

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.

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> 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 >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?)


6. 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.
