Here are the most effective steps to resolve battery drain on your S25 Ultra:

​1. Clear the System Cache Partition

​This is the most recommended fix after a major update. It removes old, temporary files that might be causing software conflicts without deleting your personal data.

​Turn off your device. ​Connect it to a computer via USB-C (this is required for modern Samsung devices to enter recovery mode). ​Press and hold Volume Up + Power until the Samsung logo appears. ​Use the volume buttons to navigate to "Wipe cache partition" and press the Power button to select. ​Confirm "Yes," then select "Reboot system now." ​2. Reset Battery Stats (Calibration)

​If the battery percentage seems to drop erratically, resetting the stats can help recalibrate the system.

​Open the Samsung Phone app (Dialer). ​Dial *#9900#. ​Scroll down and tap "BatteryStats Reset." ​Restart your phone.

​Note: You may need to disable "Auto Blocker" in Settings > Security and privacy to allow this dialer code to work.


​3. Check for App Incompatibility

​Apps often need their own updates to work efficiently with Android 16.

​Galaxy Store: Open the Galaxy Store > Menu > Updates > Update All. ​Google Play Store: Open Play Store > Tap Profile Icon > Manage apps & device > Updates available > Update All. ​Check Settings > Battery > View Details to see if a specific app is showing unusually high background usage. ​4. Wait for the "Learning" Phase

​Major updates reset the "Learning usage patterns" algorithm. It typically takes 3 to 7 days for the system to re-optimize itself based on your habits. During this time, the "Adaptive Battery" feature is retraining itself.

After this specific update ?

Can you tell me the screen on time normally?

[Kartheeban]

Everything was normal, this is security patch update. So nothing to worry. You can check your screen time. And try to check the screen resolution
