Thank you for informing us about the significant battery drain you are experiencing since the November update. We understand your concern regarding the reduced battery life.
After a major software update, it is normal for the device to perform background optimizations that can temporarily increase battery usage for the first few days.
To help resolve this and stabilize performance, please follow these steps:
Allow Time for Optimization: Give your device up to one week to finish internal background processes. Battery performance often improves naturally during this period.
Clear the Cache Partition: This action helps resolve system file conflicts post-update without deleting your personal data. (Instructions are provided in the previous message.)
Manage Background Apps: Go to Settings > Battery and device care > Battery and set rarely used applications to Sleeping apps or Deep sleeping apps to limit their background activity.
If the performance does not improve after one week, please share your device model number so we can investigate any device-specific factors.
