i want to degrade the iOS version because of battery drainage issue like 100% to 60% to 40% to 10% with in 15-20 mins and that's the problem I am facing after installing iOS 15. so I want to know how to degrade the version in iPhone from iOS 15 to iOS 14. Kindly guide me regarding the process.
You cannot do that in any way that we can discuss here. Any method of rolling back would be insecure. Concentrate on getting rid of whatever is now incompatible.
There will be a lot of housekeeping, re-indexing and photo curating going on after any update.
There may be apps that are inherently incompatible with the new iOS
Start by removing any VPN or security apps. Apart from being totally unnecessary they are also a strong contender.
Many mainstream apps need an urgent update, for example NextDoor so go to App Store and scan through your apps for those that need updating.
While there, uninstall any apps you haven't used for some time. They are unnecessary update burden.
Check the battery usage chart in battery settings for any obvious bad apps but not every background process is shown.
Any streaming apps or apps that can run with phone closed, or Clocks that hold the phone unlocked, always force close them afterwards, despite the accepted wisdom not to.
Check Settings, Privacy, Location services and make sure none of them say Always.
Check battery capacity is above 80% in Battery “health”.
Only after all that do you need to do the simple stuff advised in

In extreme cases you can backup and restore to factory.
