iPhone 12 Pro Max Optimized battery charging not working, using iOS 15.7.1

Hey there folks, so I noticed for the last two weeks on iOS 15.7/15.7.1 that I wake up to find my phone to only be at 80% charge.

Optimize charging had always worked fine for me, I would wake up seeing the messages that it would complete the 100% charge a few hours later before I would wake up at my usual time.

Now it’s only stayed at 80% never topping off to 100%.

Not sure if the software is acting up or my battery life at 84% is a factor. Should I upgrade to iOS 16.1 to resolve this?

Optimized battery charging doesn’t work for lots of people. Join the club.
Get a HomeKit compatible smart plug and set up a battery charging profile in the Shortcuts app. It’s way better controlling charging that way than that optimized battery feature that usually doesn’t work and often isn’t reliable if it does.

Optimized charging never worked reliably for me either.. I use a HomeKit smartplug and automations and it works perfectly
