Qualcomm is so obsessed with 5G, it's hurting 4G performance to spur adoption.
PCMag's Sascha Segan has been on the road testing 5G networks, and he wrote that heat was a constant issue:
While this has so far only been an issue with 5G phones, the Snapdragon's 865 could make it an issue with all flagship phones, even when using 4G LTE.
We can let Qualcomm explain the disadvantages of a separate modem in its own words, if we go back to this 2012 press release. That's when the company talks up the single-chip LTE solution it debuted in the Snapdragon S4. "Typically, the more chips that are involved in building a device, the more challenging it is to conserve battery life while maintaining performance," Qualcomm wrote then. "Consolidation means good things for your battery."
Qualcomm threw all that out the window with the Snapdragon 865. At least with the 2019 5G design—with its onboard 4G modem and the extra 5G chip—you could turn off the extra 5G chip and just use the SoC's onboard modem with the usual power savings. Now, with no onboard modem at all, even in 4G-only mode you'll be using more power by needing to light up that second chip.
Smartphone manufacturers have spent the past few years aggressively protecting the space used by components. How many manufacturers have we seen remove headphone jacks, telling us they need the space to simplify the design and free up more space for batteries? And a 3.5mm headphone jack is useful. When 5G networks remain so limited, who would want to waste so much extra internal space on 5G hardware that might never be used?
So far, the industry's response to 5G's bigger space requirements has been to make smartphones even larger. Consider the Galaxy S10 as a data point: you can get 4G versions like the 6.1-inch Galaxy S10 and the 6.4-inch Galaxy S10+, but if you want 5G, you will have to pick up the ultra-huge 6.7-inch Galaxy S10 5G, which is basically a new S10++ sku. For the Galaxy S11's 2020 release (which, remember, has to have 5G in every model), rumors point to across-the-board size increases for every model.
Financially, it's easy to see why Qualcomm made this decision. The company is probably going to make a ton of money on the Snapdragon 865, since every phone manufacturer using the 865 has to also purchase a separate modem. Qualcomm gets to sell double the amount of chips compared to last year! Since Qualcomm, according to the Federal Trade Commission, has a monopoly on high-end smartphone chips, no one can do much about this. Instead, the public will pony up for this design change in the form of more expensive devices.

PCMag's Sascha Segan has been on the road testing 5G networks, and he wrote that heat was a constant issue:
On a hot Las Vegas morning, my two Galaxy S10 5G phones kept overheating and dropping to 4G. This behavior is happening with all of the millimeter-wave, first-generation Qualcomm X50-based phones when temperatures hit or exceed 85 degrees. We saw it with T-Mobile in New York, with Verizon in Providence, and now with AT&T in Las Vegas. It's happened on Samsung and LG phones, with Samsung, Ericsson, and Nokia network hardware.
While this has so far only been an issue with 5G phones, the Snapdragon's 865 could make it an issue with all flagship phones, even when using 4G LTE.
