[How-To] Completely Stop Battery Drain In Standby Mode/Overnight Battery Drain

[Anonymous]

This post will fix one of your major issue in Samsung device.

So, battery drain in samsung devices is a very common thing, especially when the device is on standby. This is due to the system and kernal wakelocks in which certain apps, services and sensors runs in background, which is mostly unnecessary. Now usually after a certain amount of time, Android goes into deep sleep mode, but it does not reduces the drain touch extent.

So, in this how to post, I will show you how to completely stop standby drain / battery drain at night once and for all.

Steps to follow:-

1.Download and install 'Battery Guru' application from the Play Store

Don't worry it's completely free, and you no full screen ad. Moreover, you won't see any ad if you're using DNS. 

2.Open and setup the app

It doesn't require any extra work. Just some information to continue, and a button to calibrate. It will take 5 to 10 seconds.

3.Give required permissions to the app

Now, here's come an important part. Click on three dots on the top right corner>Others>Settings>Permission manager

You have to allow this permissions using adb with the help of your PC. Don't worry if you do not have a PC, you just need a wifi connection and Shizuku app. (Will explain in a later how-to post but for now google it).

4.Go to 'Save section' and enable on screen off

The final step is to go to 'save' and turn on 'enable on screen off'. Scroll down to 'Advanced battery saving options' and chose 'Extreme' and you're good to go.

Now here you can customise if you want to go to quick doze as soon as your display turns off, spoof the rest of your system that battery saver is enabled, etc. which are super helpful in certain conditions.

Note:-

1.Your alarms will not be affected by this. It will work as usual, same goes to call and messages.

2. Most of the sensors will still work, especially motion sensor, so that you can lift to wake your phone, a setting in Samsung devices.

3.Apart from this, this app is super useful. It will show your remaining battery capacity in mAh and in percentage, how much battery is consumed per hour, how much is the charging speed, which apps consumes battery, set temperature alert, notify if an app is taking huge amount of battery in background, graphs and what not. And the best part is that this app is completely free. So what are you waiting for? Go and try this out!

When i went service centre, They diagnosed my phone and said there is no problem from hardware level and they reinstall firmware. I think it is "Storage Booster" app which is consuming too much battery. Right now my phone battery is 63% after charging 100% in morning, and storage booster shows 48% battery usage.

In Battery Info it says
"Learning Usage Patterns....."
Does it mean i have to use my device for some times to get actual battery result ?

How many days ago you bought the device? Ideally after 7 days it should learn the pattern. But as the software was reinstalled, it has been reset and will take another 7 days to show.

Its has been 10 days now, but during these days i have reinstall firmware 2 times, and hard reset my device 3 times. I think i should wait till this learning pattern over ...

On Android 13, it gives option of details when msg like "Some system apps or processes are overloading CPU. Please restart your device" pop up. And i found that some Biometric process is overloading CPU. And because of that device does not go into deep sleep.

I think this may be single most reason for all samsung device. May be someone have another process which cause battery drain, but in my case it is biometric process.

HI there, the save section is absent in my battery guru. Is there another way of enabling the screen off?
