Battery drain

Hi! Yes, what you’re experiencing is completely normal after a major update like One UI 7. The system needs a few days to re-optimize apps and background processes, which can cause temporary fluctuations in battery life.

Here are a few tips to help:

• Give it 3–5 full charge cycles for the system to settle.
• Go to Settings > Battery > Background usage limits, and put unused apps to sleep.
• Wipe cache partition from recovery mode (safe and effective after updates).
• Keep an eye on Battery usage stats to spot any apps draining unusually.
• Make sure all apps are updated to the latest version via Galaxy Store & Play Store.

Sounds like your first-day stats were promising, so it should stabilize again soon!

Its definitely normal. All users experience battery drain after One Ui 7 for all devices. Turn on the battery saving options and use your phone as normal. After like 1 week the phone will get used to the new update. And after Samsung releases the next security update for your S23 FE. The battery will improve Bro. Hope my comment is helpful for you.

After an update, it is normally to drain battery fast because the device need to understand the usage of it.

If after several days ( max 1 week ) that not works,

1. Try to wipe Cache Partition
Or that did not help

2. Flash the official firmware using odin ( backup the device data )
