Qualcomm recently took the wraps off its flagship SoC for 2020, the Snapdragon 865. As usual, we can expect this chip in all the high-end Android smartphones in 2020, and it's 25 percent faster than last year, with fancy new camera features and AI-accelerating co-processors. What's unusual is the way Qualcomm designed the LTE modem in the Snapdragon 865: it doesn't have one.

This means nearly every flagship Android phone will be a 5G phone in 2020, and putting the 5G and 4G on a giant extra chip means smartphones are going to use way more more power, no matter which cell network you're connected to. When 5G networks are only going to be in their infancy in 2020, this sounds like an across-the-board downgrade to me.
