Update 16.1.1 = battery crazy

I have iPhone 11…since update battery dies within hours! I updated yesterday….noticed battery dying quickly…went to settings-battery to see what was using so much..nothing unusual battery health 84%. Today battery completely dead in 3 hours…went to settings- battery and battery health is now 82%. Something weird happened with this latest update…..this is not good!

I'm glad that's figured out. The long process of applying an iOS update to an old iPhone 8 with its already weak battery can be the proverbial "straw that broke the camel's back." Then the iOS update is mistakenly blamed.

Yes, a newer phone would be good, but your iPhone 8 will sell better with a new battery:

...Or simply trade it in with its original battery at Apple:

Plebeyo ~ To be clearer, this icon is the Settings app:

...Tap it to open Settings app. Then scroll down to Battery and tap it. Then tap Battery Health and tell us what the Maximum Capacity % is. If its value is only "––", let us know that.

100% max capacity is unlikely for an original iPhone 8 battery. So is that the current charge % rather than the Maximum Capacity % I asked for here?...

Settings > Battery > Battery Health

iPhone useless on16.1.1

Battery dies quickly.

How do I remove 16.1.1 ?

Plebeyo ~ Does your iPhone 8 still have its original battery?

And what's the Maximum Capacity % here?...

Settings > Battery > Battery Health

Thanks. In that same Battery Health pane, is there a message saying something like: "the battery is significantly degraded"?
