But Tello’s latency was significantly higher in general—not enough to affect a game of Royal Match, but maybe you have higher demands. The download speeds were also lower for Tello in any given location, but not by a whole lot. At home, my cellular 5G data speeds tend to run at about 800 to 900 megabits a second on T-Mobile. With the Tello phone, it was around 30 percent slower. But both these speeds are well into 5G territory. They’re also a full order of magnitude faster than you’d ever need for 4K video. I had no problem streaming my usual dose of Josh Johnson comedy, if that’s what you’re wondering. Curiously, upload speed was actually faster with the Motorola Razr using Tello than with the old iPhone using T-Mobile. After consulting with my colleague Julian Chokkattu, who has covered phone advances for years, I’m likely to chalk this up to improved modem performance by the newer Motorola, not a secret backdoor to faster uploads by Tello. It’s only in areas with degraded or 4G …
