Ars’ latest feature supports the theory that being an early adopter rarely pays off: while 5G has the potential to offer a “10x improvement” in mobile network speeds, the first devices won’t be blessed with an SoC, but separate, larger components such as a discrete modem and multiple antenna modules. Critics suggest poor battery life and weak 5G reception are therefore inevitable, as additional hardware will result in a smaller battery, and multiple RF modules highlight how easily a user’s hands could block a signal. In a year or two, mmWave hardware should be more mature and more integrated. A big sign to look for is if Qualcomm's 2020 SoC has an integrated 5G modem, which would bring back many of the single-chip advantages that 4G has today. The immaturity of 5G won't stop the coming advertising blitz, though. Soon you'll start seeing the launch of the first 5G phone on network X, and every carrier on Earth will be advertising 5G as the best thing since sliced bread. Don't believe the hype. For the near future, if you can buy a 4G version of a phone, you probably should.
