Iphone 16 battery drain

It’s been a year since I have been using my iphone 16 and the battery capacity is at 91% and 558 charge cycles have been completed but the charge on my device doesn’t seem to be lasting at all since it drops by 25% within an hour I have tried using every possible method to retain battery life is but there hasn’t been any improvement if anyone had a reason or an answer behind this problem and how it can be solved it would be of great help

A 25% drop within an hour indicates severe battery drain that goes beyond normal chemical aging, even with 91% capacity and 558 charge cycles.

Please try this

Check Specific Usage: Go to Settings > Battery to inspect which apps or background processes are consuming the most power during these rapid drop periods.

Reset All Settings: Go to Settings > General > Transfer or Reset iPhone > Reset All Settings. This clears out corrupted configurations without deleting your personal photos or apps.

Set Up as New : If a software bug from a restored backup is causing the drain, back up your data to iCloud, wipe the phone, and set it up as a new device rather than restoring from the old backup.

Recalibrate the Battery: Let your iPhone drain completely until it turns off on its own, then plug it into a wall charger and charge it uninterrupted to 100% (leaving it for a few extra hours) to help realign the percentage readout.
