Downgrade IOS 14 to IOS 13
Is there any safe and reliable way to downgrade from one version IOS to a lower version? I have an Iphone 6s and it has the latest IOS software installed, but since this update the phone is super slow and battery life is non existing. Battery health is 100% (was replaced a month ago). Phone gets warm and has glitches all of a sudden.
