Never thought iPhone 13 has bigger battery than iPhone 13 Pro.

It's almost as if they deliberately added this seemingly bad option so people would choose the most expensive option iPhone 13 Pro Max. Because it would seem like the best deal out of three. I mean the Pro Max is just $100 more expensive than Pro, right?

But remove this decoy option, and most people would just buy the iPhone 13.

I see what you’re saying, and that’s an interesting argument. But a counterpoint:

> On the iPhone 13 series, there’s a few complex behaviours to consider: First off, the iPhone 13 Pro and its LTPO panel noticeable decreases the minimum baseline power consumption of the phone by around a massive 100mW… While 100mW doesn’t sound much, when using the phones at lower screen brightness, this can represent a large percentage of the overall device power consumption, and vastly increase battery life for the new iPhone 13 Pro models.

> Comparing the 13 to the 13 Pro, the phones have quite different curves – while the 13 Pro uses less power to display full white up until 140 nits, the regular 13 becomes more efficient afterwards. We’re also seeing different curve shapes, meaning the phones are driven differently in regards to their PWM and emitter voltages.

The Pro phones are more battery efficient than the regular ones, and probably use the extra space gained with a slightly smaller battery for some other featureful hardware (cameras?).

The trade offs made seem to be reasonable for a Pro that’s between the regular and the Pro Max. It doesn’t seem to me like just a decoy.

Literally everyone I know with a Pro owns the regular-sized Pro.

The $100 is irrelevant to the target market of the Pro line, it's basically pocket change. You buy the phone that's most comfortable for your hand because that matters way more than the $100.

This makes no sense; virtually nobody is picking which phone to buy on the basis of 130mAh of battery capacity, and these are different devices to boot with different screens and cameras.
