Battery Draining Issue After Latest iQOO 15 OS Update on Neo 7

Hello iQOO Team,
After updating my iQOO Neo 7 to the latest 15 OS, I have noticed a significant increase in battery drain. The device that previously lasted comfortably throughout the day is now depleting much faster under similar usage conditions.
Is this a known issue, and are there any optimizations or fixes planned in upcoming updates? Any troubleshooting suggestions would be appreciated.
Looking forward to your response.
Thanks!
