Rapid Battery Drain After One UI 7 / Android 15 Update on S24 Ultra and S23 Ultr

[The_Wildfire]

 I've encountered a serious issue after updating both my Galaxy S24 Ultra and Galaxy S23 Ultra to One UI 7 and Android 15 (April update). Since the update, I have noticed a significant increase in battery drain on both devices.

Before the update, battery performance on both phones was excellent. However, now the battery depletes much faster than usual, even with minimal usage and battery-saving features enabled. This issue is affecting the usability of my devices throughout the day.

Using it in power saving mode. It's okay. Not sure, but battery performance decreased after the update.
