Battery Problem in A30

[SanRay2001]

I found a prob in my battery that like one day when the charge went to 19% suddenly it started rapidly reducing to 10% then 5% then 0% within a minute.

And also one other thing I charged my phone till 80% then the auto restart took place as scheduled in night and after that I see is it is charged 100% 

Is this a serious problem?? @interchupipi please respond to this. I need a solution from you people🙏🏼🙏🏼🙏🏼

sorry i replied, inspite of reading that you want solution from "interchupipi "
if always happened after 19% then once go to safemode just before 19%, if this is not occurs in safemode then its a software update issue in this case you need to visit service centre and get reinstall your software update, or if in same thing happened in safemode then also go to visit service centre and explain the issue it may cause due to some hardware issue

steps to turn safemode;
long press on power button>
long press on power off option>click on safemode >your mobile will restart and turn into safemode.

Keep in mind that in this mode only inbuilt system app will work

[SanRay2001]

Can this safe mode be turned off??? And does this delete any of my data because I have never used this

[Ehsank]

not delete anything from your mobile, and once you enable you will get one option in notification panel to restart your device, and once restart you mobile turn into normal mode

and if 19% is not fixed as you said its only one day happened but your battery drain in idle mode or gradually drain then
do some 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 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. Google >click on 3dot at right top corner>usage and diagnostics >off this option.
