iOS 15 and Battery

This iOS 15 update is absolutely draining my battery. I’ve restarted my phone. Closed all my apps. Nothing is working.

Does the iPhone 6 still have its original seven year-old battery? If so, what's the Maximum Capacity % here?...


Settings > Battery > Battery Health

Note that the long process of applying an iOS update can be "the straw that broke the camel's back" for a weak, aging battery.
