Hi @fadi00,
A drop in battery life after an update is often normal: the operating system changes and interacts differently with services, temporarily affecting power consumption.
A major update can also cause temporary instability because the system, having to process a large amount of new information quickly, keeps the CPU and internal resources constantly active. This leads to a temporary increase in consumption, but once the new instructions are “learned,” everything tends to stabilize.
To help speed up this stabilization, we recommend performing a wipe cache partition. This procedure is safe, does not delete photos, videos, apps, or messages, and helps remove outdated temporary data that may affect performance. It is also useful in case of slowdowns, crashes, or other abnormal behaviors after an update.
1. Completely turn off the smartphone.
2. Connect the device to a computer using a USB cable.
3. Press and hold the Power and Volume Up buttons simultaneously.
4. When the "Samsung" logo appears on the screen, release only the Power button, keeping Volume Up pressed.
5. Wait for a blue screen with the Android symbol or a warning message, then release the Volume Up button as well.
6. The recovery mode menu will appear: use the Volume Up and Volume Down buttons to scroll through the available options.
7. Select "Wipe cache partition" by highlighting it with the volume buttons.
8. Press the Power button to confirm the selection.
9. On the next screen, move to "Yes" using the volume buttons.
10. Press the Power button again to confirm the cache deletion.
11. When the process is complete, the recovery menu will appear again. Select "Reboot system now".
12. Press the Power button to restart the device normally.
