This guide is specifically for Ivan Meler's LineageOS 18.1 on the s10e, but most of the guide should work universally through Android Versions, ROM Variants and Devices

What you can achieve:
9Hrs Screen On Time
20-40Hrs Screen Off Time
Working SafetyNet
Working GCam
High Stability


IMPORTANT
Since all my testing is done on one ROM and one phone, it may lead to issues on anything else. As I said, it should work, but I can give no guarantees as each ROM, Device, Kernel, Android Version and different combinations of all these things have their own quirks

I am not responsible for any damage you might cause to your phone, I am simply sharing my insights on my process when I install a custom ROM

Make sure to read through EVERYTHING at least once before getting started

It's better to start with a fresh install, but it should work dirty so long as you unninstall all existing Magisk and EdXposed modules first

Follow my instructions as carefully as possible, I can not help you if you do anything differently

Follow my instructions in the right order to avoid issues

As this guide is primarily focused on getting the most battery life out of your phone, it is absolutely NOT friendly towards graphically intensive games. Though most games should work fine

Your Screen On and Screen Off time's may vary depending on your ROM, installed apps, usage, battery size, battery health, the processor's underclocking capabilites and screen resolution

SOME BASIC TIPS
-Turn off location, NFC, WiFi, Bluetooth, Hotspot and Mobile Data whenever you're not using them
-Try to keep your screen brightness as low as possible, as high brightness eats up a lot of battery
0-50% brightness makes less difference to battery than 50-100% brightness
-Only charge your phone to 80%, this will help your battery last longer
AccuBattery will help you with this by notifying you everytime your phone reaches 80% charged
You can always charge to 100% when you know you'll have a long day


BADGES
This guide has badges on each of the steps, each badge will help you understand which is important to the guide and which you can skip if you choose. These badges are determined by this guide's core goal, which is to massively improve your device's battery life.
CORE - I would not suggest skipping any steps labelled with this
RECOMMENDED - You'll be fine if you skip these steps, but I would suggest you do it
OPTIONAL - There's no problem in skipping a step with this badge
WARN - These steps are necessary on any s10e/s10/s10+ running LineageOS 18.1, but may or may not be different on any other device or ROM
S10 - These steps only apply to the s10e/s10/s10+
LINEAGE - These steps only apply to Ivan Meler's LineageOS 18.1

Frequently backup your device's state, should anything go wrong you can just roll back. It's important to make a backup every few steps or so
Unless you're installing this on an exynos s10 device using Ivan Meler's LineageOS 18.1 ROM, then no backups are necessary until the very end, granted you follow my instructions properly

HOW TO BACKUP
I use TWRP for backing up, use your own method if there is something you're more comfortable with
-Once you have installed the ROM, boot into TWRP
-Open Backup
-Include Boot, System Image and Data
-Swipe to Backup
Done, that's it

NB! Delete any old backups before making a new one, and make sure your last backup is done BEFORE installing any massive apps, as huge app sizes can make it impossible to store the backup on your phone.

LET'S GET STARTED

INSTALL YOUR ROM

This step will vary based on device and ROM, follow the setup guide on your ROM's page
-For LineageOS 18.1 on any s10 device S10 LINEAGE
-You can skip installing GApps if you are not tied to Google's ecosystem
-Root with Magisk CORE

-Reboot

Now if you've made it this far, it's time to get down to business

BASIC SETUP CORE
-Get Magisk working
It might work out of the box. Or you'll need to manually install the manager, either by clicking on Magisk Manager in your app drawer and following the steps, or installing it via an apk
-Your device might reboot once it's setup
On Ivan's LineageOS, you'll find it without an icon in your app drawer at first. Run it and say yes to everything it asks, your device will reboot when it's done

-Install Termux (Or your preffered terminal on android) here or here
-Install Naptime here or here
-Install Greenify here or here
-Install SmartPack here or here
-Install LSpeed here
-Install AccuBattery RECOMMENDED here or here
-Install a better launcher RECOMMENDED
I recommend Nova Launcher as it is feature rich, performant and battery light here or here
You will need a good launcher that can help you hide away all these apps when you're done

-Open the AudioFX app and disable it S10 LINEAGE
This has led to people complaining that the speaker has no bass, this fixes that and restores loudness

-Open Settings
-Open apps and notifications
-Cick on see all apps
-Disable Digital Wellbeing
-Disable Pixel Tips and clear its storage and cache

-Go back to apps and notifications and expand the advanced menu
-Click on special app access and then battery optimisation
-Enable battery optimization for any google apps
-Click on not optimised at the top and change it to all apps
-Disable battery optimisation for AccuBattery, Greenify and Naptime

-Go back to settings and open battery
-Turn on Adaptive Battery
-Turn on automatic battery saver from 25%

-Go back to settings and open display
-Open the advanced menu
-Set your screen timeout to 30 seconds
-Click on lockscreen and disable always show time and info, and wake screen for notifications and then go back LINEAGE
This is essentially turning off AlwaysOn Display
-Enable tap to wake and disable tap to sleep OPTIONAL
-Enable high touch sensitivity

-If you have google installed, go back to settings and open google
-Click on the three dots in the top right and open usage and diagnostics
-Disable it

GET SAFETYNET WORKING WARN
Most newer devices will need to follow these steps to get SafetyNet to pass, but on older devices it'll be different

These are installed as Magisk Manager Modules

-Open Termux
-Enter su
-Grant it superuser privelage
-Enter props

-Click on the search button in the bottom right and show system apps
-Add Google and Google Play Services to the checklist
You should also add any banking apps and certain games that don't work with a rooted phone to this checklist
-Reboot

SafetyNet should be working
If you are installing EdXposed as well, then you'll need to do some extra steps to keep SafetyNet passing, which I'll explain later

My config is:

Screenshot_20210203-014620_AccuBattery.png
Screenshot_20210203-014628_AccuBattery.png

Since my battery is at 87% health, you take the Screen On Time and divide it by battery health percentage, and times it by 100 to get Screen On Time with a fresh battery
8x60=480
480+16=496
496/87=5.7
5.7x100=570
570/60=9.5
9.5 hours Screen On Time With a Fresh Battery

This guide is way underrated. Everything is well explained and organized. Thanks to this guide I finally bypassed SafetyNet while getting a better SoT. Thank you sir.

Was really discouraged when I originally posted this, but I'm glad to see that I could help some people.

So I'm going to keep updating this guide and making it better for everyone.

Thanks for the support!
