The Note 20 Ultra has some really big cameras.

The Galaxy Note20 Ultra met the hands of iFixit's teardown specialists and gave us a glimpse into Samsung's latest flagship.
If the super large camera bump didn't recognize you from the outside, it's clear that Samsung needs a lot of space inside for the multi-camera setup. Even iFixit says it is "remarkable how much additional space the [Galaxy Note 20] Ultra devotes to its camera modules". Samsung is doing its best on the outside to make all lenses look the same, but in fact the middle 108MP sensor is much larger than the top wide-angle sensor, and the bottom periscope camera is an even larger side assembly.
Multiple cameras have become an almost mandatory marketing tool in the smartphone business, but I hope that users will make a living from actually using them. Every large component in a smartphone takes up other functions or additional battery capacity (see: the argument of the headphone jack). With a single camera, Samsung and other manufacturers would have a lot more room to play.
When we talk about optional components that take up a ton of space, a cute x-ray shows us how much space the Note's S-Pen takes up inside the device. The entire battery needs to shrink horizontally to make room to store the pen. If we compare the Note 20 Ultra with the S20 Ultra, we see that the S-Pen costs around 500 mAh battery.
Another fun tidbit in the report is that Samsung gets the Note 20 Ultra's cooling solution from two sources. Some devices have copper vapor chambers while others have graphite thermal pads, and so far no one has determined exactly which devices have which cooling solution. So far there have been no claims that one cooling solution is better than the other, but the Note 20 hasn't been around for that long.
Samsung (and many other manufacturers) often use dual source components for their high-volume smartphones. The best-known examples from Samsung are the SoC products, where phones in Europe and some other regions get the Exynos chips from Samsung, while phones in the US and China get Qualcomm chips. Dual sourcing is of course not always limited to regions. Samsung is also known to use Samsung and Sony camera sensors interchangeably, and dual source battery suppliers are often used. Ideally, dual sourcing does not matter at all, as the two parts are supposed to be very similar in their performance and many were built to the same specification. This isn't always the case, however – pretty much the world recognizes that Samsung's SoCs are inferior to Qualcomm, and Europe only tipped the scales in that deal.
iFixit is not satisfied with the overall construction, which has a lot of glue to contend with during a repair. One of the most common repairs, changing the screen, is more difficult than necessary as the display is one of the last components to come off if you tear it down. The phone scores 3 out of 10 for repairability.
