wipe cache partition gone after android 11

[ninus]

After updating my s10e to android 11 my battery started draining super quickly, needing about 2 full charges a day. So I thought I'd wipe my cache partition, but I can no longer access the menu. I've tried with and without usb-usb c connecting it to my laptop and then pressing vol up+bixby+power button but every time I just get a normal reboot. has anyone found a fix for this?

It changed with Android 11, now you need to plug the USB-C / micro-USB cable along with the combination buttons (Press & Hold the Power and Volume Up button)

you can enter recover mode by doing this
connect ur device to pc by usbc cable
and make sure ur device is visible in computer as logged in
turn off ur device with the cable connected to pc
and now hold power up and switch on button together until the recovery menu pops up

first enable developer options and then oem unlocking enabled then follow regular steps to view bootloader screen to wipe cache partition and also u need to plug usb-c cable to laptop or PC .
not sure why they have kept such weird process but it worked for me after doing this.
once you are done you can disable oem unlocking and developer options if not used for security reasons

i didnt know i had to check whether my device was visible in computer as logged in, which is where it went wrong for me but it worked now! thanks so much for replying :)

OEM unlocking? No, there is no need.

somehow after enabling oem unlocking only helped to show bootloader option on my s20 plus

but clear cache is not enough to save battery if you want to these few more settings 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.

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 app(LIKE FACEBOOK, YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info(ibutton)>> 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> Manage 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 weather settings (icon)> 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.
