I leave mine at 25% and find this brightness setting perfect, except when I’m out in the sun then I’ll bump it up to 50%. This is on the iPhone 11 Pro Max.
 
I use an Auto Brightness jailbreak tweak to control my brightness. It requires the stock Auto Brightness to be off and it adjusts my brightness on the fly.

How is auto brightness on the battery? What is the lowest setting that it will adjust to?

The trick to stock Auto Brightness is to turn it off, set your brightness slider all the way down and then turn Auto Brightness back on. It will adjust and maintain to the ambient light wherever you are while always trying to keep brightness to as minimum as possible. That saves on battery.
 
0-20% unless I'm under the sun.

Auto Brightness sets the brightness too high for my taste so I just have that disabled.

Was excited to try this but nope. Still way too bright. After I enabled Auto Brightness, it went all the way to 50% in ambient lighting where I would normally keep the device at 20%.

I have auto-brightness turned on, however, I manually adjust it all the time to as low as I can handle it - it eventually learns and I don't have to bother with it anymore. I find reading on a darker screen easier for my eyes - always have to bump it up when I show other people pictures, my screen.

Well, it depends on your ambient light I suppose. If you did it outside on a sunny day or in a well-lit room then it tends to act this way. But, stock it's the best you can do if you want things to adjust automatically.

That's one of the reasons I installed the jailbreak tweak I have. It's much better at it.

Woah I didn't know this, how'd you find this out? What I would usually do was just switch autobrightness toggle off and then on and I thought it left it on stock brightness settings. Hmmm, I'll see if it's the same thing.

I figured it out because I was fooling with it. I set it how I wanted it and then turned Auto Brightness on. It jumped forward (brighter). Which annoyed me. After a few times like that, I turned it off, dragged the damn slider all the way down and then turned it back on. While it did jump up some for me, it was acceptable and nowhere near the jump it took previously.

I tried and it set mine as you like it, 20%. However, too low for me. 50% better for me.
 
75% pretty much always unless I need to turn it down for certain circumstances. I like it brighter than most.
 
I use auto-brightness and it usually sits at around 25%, except when the display is under direct sun light.

0% brightness in complete darkness, unless I'm watching a movie or something. In that case I'll bump it up to like 15-20%.

Overall I let the phone do its thing with slight, rare adjustments from myself.
 
I normally keep it at 50%. I tried using auto brightness once and at one time I had just checked my iPhone in the early hours of the morning and the brightness went up so bright automatically I had to dim it down. That put me off auto brightness. Plus I think that auto brightness may use more battery power than normal. Unless I am wrong.

The sudden brightness increase issue you had experienced may have been a bug. I suggest you give it a try again. Especially if you have one of the newer devices.

Auto brightness will typically use less power unless you always keep the brightness to the lowest end.
