After a new update that is the 1st December security update there is a noticeable battery drain on the Note 9. The update was around 102 mb and after this there is a battery drain noticed.  Anyone else suffering the same? 

Thanku in Advance.

and if you not done yet then do some settings to save more battery life and observe for next 1-2 days, it will give a noticeable difference

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

2. Settings>>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 app(LIKE FACEBOOK, YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info> 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 you not using that apps much, 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 > check which 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.

aa gaye cut copy paste reply karne wale

[Ehsank]

ek hota hai khud ka content ho or usko har jaga likhne se achha copy paste karna, jaise har aqalmand log karte hain specially jo log computer/digitally work karte hain
an chahe wo teacher ho ya engineer ya doctor ya koi data enntry operators , to ye smart work me count hota hai
or ek hota hai dusre k content ko copy paste kar k or khud ka bata kar aagey serve karna jise cheating, fraud, copier, kehte hain
to isme pehle difference karna seekho

or ye batao k tumko kuch knowledge hai or usse related bahot frequently issue aatw hain to tum har baar type karoge ya usko main place se copy kar, paste karoge?

kai baar logo ko nahi malum hota to wo us post/article ya web page ka link bhi copy paste kar dete hain to ye kaisa hai tumhare nazar me?
agar tum student ho to jald hi jab mature or professional field me aaoge to samjh jaoge or professional ho to baat se tumhare lagta nahi hai
