[Samsung Galaxy S23 Ultra] android updates and roms:
Hey everyone, I wanted to share some tips on how to improve your phone's battery life. However, I also want to point out some negative aspects of the customizations and privacy practices by Samsung and Google. Here are my recommendations:

Turn off all Wi-Fi intelligent services - they are not necessary.

Disable Google's digital well-being by restricting usage data as it can drain your battery.

Use LTE instead of 5G and manually register your network instead of automatic registration.

Create routines based on time and Wi-Fi, not location-based.

When you get a new phone, charge it from 15% to 100% for at least three days so the device can learn on usage. Then, toggle to protect the battery.

Disable all Google unwanted services in the "Google" settings page, including Nearby devices, casting, reset ads, location sharing, nearby share, find my mobile, earthquake alerts, Wi-Fi, and Bluetooth scanning, and send diagnostic data.

Enable Google location accuracy and Nearby devices scanning under Samsung settings.

Disable UWB, Samsung customization, ads, and marketing things, and send diagnostic data from Samsung settings.

You can use QHD, 120hz, and light performance modes without worrying about battery life.

Do not use any battery monitor applications.

Use alternatives for original apps, such as Frost for Facebook and Sync Pro for Reddit.

Do not put any apps in deep sleep.

Install the battery tracker, thermal guardian, and battery guardian from the Galaxy Store and leave them running for at least 10 days. Battery guardian will help you find shady apps that run in the background.

Disable the My Galaxy application.

Uninstall Samsung apps if you do not use them, such as Samsung Smart Device, Smart Tutor, and Samsung Pay.

Stop backing up your data automatically all the time, unless you are at risk of losing your phone.

Use a Samsung charger and cable for charging.

Use the Always On Display sparingly.

You can play games on this phone for a long time without battery issues as the phone does not overheat.

Disable Nearby Share and Quick Share and only use them when you need to.

Be mindful of the apps that require notifications, otherwise disable notifications for the apps you do not need.

Do not run location all the time; instead, create a routine that enables location when you open banking, grocery, food apps, or maps.

Do not use modded apps as they may have serious security issues. Instead, subscribe to real apps, such as Spotify, Medium, and Balance for Meditation.

If you have a Galaxy Watch Classic, do not use the step counter in your phone, and do not provide physical activity permission to the Samsung Health app. Your watch will count the steps and other workouts, and then it will automatically sync to your phone.

Turn off sync if you are not using it, such as Google Calendar or Keep Notes.

Turn off Bixby and OK Google if you are not using them to avoid data collection.

Enable 0.5x in the transition settings under developer options.

Uninstall all meta inbuilt apps through adb, but do not uninstall Samsung apps via adb as it may cause issues.

Use the app booster in Galaxy Good Guardian and run it once, then run it monthly.

Do not update your Samsung firmware right after its release. Wait for a few days and ask peers for feedback before updating the phone. This way, you can skip the current update and update the phone directly to the next version.

Avoid clearing the cache partition every time after an update. Instead, it's recommended to run the app booster after updating and charge your phone to 100% at least twice before using the battery protection feature.

Lastly, review your app permissions again after using your phone for a month and take necessary action to turn off or limit permissions if needed.

Thanks for reading! Feel free to comment if you have any ideas or settings that are shady!
