Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

Apple Says A13 Bionic Chip Was Designed With Performance-Per-Watt Focus
In a feature for WIRED, Om Malik sat down with Apple's marketing chief Phil Schiller and chipmaking engineer Anand Shimpi to discuss the A13 Bionic chip in the new iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max.
Malik first provides an overview of the A13 chip's specs and performance improvements:
"We've enhanced our iOS 13 text-to-speech capabilities such that there is much more natural language processing, and that's all done with machine learning and the neural engine," Schiller explained.
Shimpi noted that when designing its A-series chips, Apple focuses on both performance and efficiency. "We talk about performance a lot publicly. But the reality is, we view it as performance per watt. We look at it as energy efficiency, and if you build an efficient design, you also happen to build a performance design."
The article notes that Apple's chipmaking team will study how apps are being used on iOS devices to optimize future chip designs. "For applications that don't need the additional performance, you can run at the performance of last year's and just do it at a much lower power," Shimpi said.
Machine learning also plays a big role in the A13 chip, helping to manage battery life and optimize performance, according to Schiller. "There wasn't machine learning running ten years ago. Now, it's always running, doing stuff."
Malik first provides an overview of the A13 chip's specs and performance improvements:
- 8.5 billion transistors, an approximately 23 percent increase over the A12 chip's 6.9 billion transistors
- Six-core CPU: two 2.66GHz high-performance cores named Lightning and four efficiency cores named Thunder
- Quad-core graphics processor, an Apple-designed image processor, and an octa-core neural engine for machine learning that is capable of one trillion operations per second
- Up to 20 percent performance increase across all of the main components, including the CPU, GPU, and neural engine
- Up to 30 percent more power efficient than the A12 chip
"We've enhanced our iOS 13 text-to-speech capabilities such that there is much more natural language processing, and that's all done with machine learning and the neural engine," Schiller explained.

Silicon design team doesn't get enough credit - they've made an incredible chip compared to the competition.

For those wondering, yes, that is Anand Shimpi, founder of AnandTech. I freaking love that he is a chipmaking engineer at Apple now.

1 trillion operations a second...... I can't even begin to imagine. It's mind boggling to think how far we have come since the original iPhone

In other words, it's based on ARM A77+A55.

Nope. Apple A* chips aren't based on ARM Cortex designs. They implement the ARM ISA, but don't use ARM's designs.

Still posting these lies? It appears you have no understanding whatsoever of what an ISA is vs a micro architecture.

If Apple was two years ahead of everyone on efficiency then they wouldn't be last on battery performance.

More likely iPhone 11 Maxi Pro with 25% bigger battery will catch up with competitors on the next comparison video based on iPhone Xs Max 5h 48m result +25% battery increase so ~7h 15m.
Comparing a device with a battery that is roughly at least 900mAh smaller than the rest would probably account for it dying before the others in this video.
