iPhone 13 Review Shows Impressive Battery Results

We saw Apple executives on stage mention one or or one-and-a-half extra hours of battery with iPhone 13 models. This review proves it.

Apple was careful not to promise any specific battery life on the new iPhones. I think that’s because of 5G. Depending on 5G frequency and signal quality, the battery life you get can be much shorter than you see here—and the 5G situation is so confusing across different carriers and countries that I don’t think Apple was willing to make a generalization. Of course, you can always turn off 5G.

iPhone 13: How Cinematic Mode Was Made

Cinematic mode was one of the big new features in the iPhone 13. In a new interview with Techcrunch, Apple VP Kaiann Drance and Human Interface Team designer Johnnie Manzari explain how it was made.

“We knew that bringing a high quality depth of field to video would be magnitudes more challenging [than Portrait Mode],” says Drance. “Unlike photos, video is designed to move as the person filming, including hand shake. And that meant we would need even higher quality depth data so Cinematic Mode could work across subjects, people, pets, and objects, and we needed that depth data continuously to keep up with every frame. Rendering these autofocus changes in real time is a heavy computational workload.” The A15 Bionic and Neural Engine are heavily used in Cinematic Mode, especially given that they wanted to encode it in Dolby Vision HDR as well. They also didn’t want to sacrifice live preview — something that most Portrait Mode competitors took years to ship after Apple introduced it.

Photographer Austin Mann Reviews the iPhone 13 Camera

Photographer Austin Mann has published his review of the iPhone 13 Pro camera. He travelled to Ruaha National Park, Tanzania, to put the device through its paces. He has a video below as well as a written blog post about the camera. “The most substantial hardware improvement in the iPhone 13 Pro camera system is the all-new 13 mm Ultra Wide lens with a much faster f/1.8 aperture (about a stop faster than the f/2.4 Ultra Wide lens in iPhone 12 Pro). The larger aperture means better light collecting ability, which should result in sharper low-light images with faster shutter speeds.”

Here's Why iPhone 13 120Hz ProMotion Display Matters

Rebecca Isaacs has written a helpful explainer about the iPhone 13’s 120Hz display and why it matters for customers.

One of the major selling points of this technology is that it allows you to dynamically vary refresh rates based on what you’re doing. For instance, basic web browsing can be handled at an undemanding 10Hz to 60Hz, while gaming can take advantage of the full of 120Hz. The Apple Watch can even hit a low of 1Hz with the always-on screen.
