Samsung's Galaxy S20 Ultra goes on sale tomorrow (March 6). A new report details the phone's camera sensor and details how Samsung managed to fit so much into an 8.8mm thin casing.

These details come from the gadget repair geniuses at iFixit, who performed an ultra-tight disassembly of the S20 Ultra. They did a close-up comparison of the 108 megapixel camera to the iPhone 11 Pro Max's 12 megapixel sensor.

For starters, iFixit took a close-up look at how the Galaxy S20's 108-megapixel camera fits 108 megapixels into a 9.5 x 7.3 mm rectangle. This translates to 1.5 million pixels per square millimeter, which is difficult to visualize. Of course, Samsung knows that this infinitesimally small pixel works better in low-light conditions by a trick called "pixel binning," which captures more light.

And while you wouldn't notice the huge camera block on the back, Samsung has managed to fit a lot of stuff inside it (including a 100x zoom sensor) with a clever trick: the S20's zoom lens is rotated sideways, so that a prism is between the image, sensor, and lens to " bounce the light sideways." iFixit then explains that "the prism moves back and forth... . to compensate for camera shake," and found a support bracket that "compensates for camera shake.

In other spec-released details, iFixit confirmed that the S20 has a 5000mAh battery (first heard of last December) and that the phone runs at a total of 19.30 watt-hours. This power consumption is greater than the iPhone 11 Pro Max (15.04Wh) and the Galaxy Note 10+ 5G (16.56Wh), but not shockingly high.

We found no details that would explain the shortcomings of the S20 Ultra's camera zoom; in-house at Tom's Guide headquarters, we observed that the camera would stop for a moment before actually focusing on a fairly close object, causing the focus to skip. The iPhone 11 Pro Max, on the other hand, had no such problem.

This kind of problem in a very expensive phone was described to my colleague Mike Prospero, senior editor of Tom's Guide, as The Galaxy S20 Ultra had one job - and Samsung screwed it up. Ultra had one job - and Samsung screwed it up), the kind of annoying problem that made me write a great editorial. Of course, Samsung is offering a fix.
