[MeetS23ultra]

My issue list

1. Over heating in day to day work(no improvement)

2. Battery drain is high as always 

3. Network issue with jio 5g. No sound when I first connect the call.

4. Internet speed issue. Like no constant speed & same place give high speed & then drop to 0 then again goes to high speed.

But why every major update from Samsung always suffer from battery drain issues ?? 

[Dr_Cellophane]

Battery drain issues after a major software update on a Samsung phone are common for several reasons:

Background Optimization: After a major update, the phone starts background processes to re-optimize apps, recompile them for the new software version, and rebuild system caches. This can be a resource-intensive task that causes increased power consumption and may take a few days to complete.
New Features:
Software updates often introduce new features and system-level changes that may run in the background and consume more power, such as automation routines or new location-based services.
Software Bugs: Even after extensive testing, an update can contain bugs that cause unexpected battery drain. These bugs may not affect all users and a patch to fix them is typically released later.
App Incompatibility: Some third-party apps may not be fully optimized for the new operating system version, which can lead to higher background usage and increased battery drain until the app developers release their own updates.
Reset Battery Optimization Settings: Major updates can sometimes reset the phone's battery optimization settings, which track user habits. This forces the device to "re-learn" your usage patterns, leading to higher power consumption during this period.
Increased Usage: New features and visual changes in an update can encourage users to spend more time on their phones, which naturally increases screen time and resource usage, leading to faster battery drain.

Potential solutions and troubleshooting steps include:

Wait a few days: The most common advice is to wait at least a week for the phone to complete its background optimization processes and for the battery life to stabilize on its own.
Update all apps: Ensure all apps, including those from the Google Play Store and Samsung's own Galaxy Store, are up to date to avoid compatibility issues.
Clear the cache partition: This step can clear temporary system files that might be causing conflicts after an update.
Review settings:
Check your phone's battery and power-saving settings to make sure they are configured as you prefer.
