iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. Battery drain issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.
This seems purely coincidental so please check the Setting on your device. Prolong and Maximise Battery Performance … - Apple Community
