If you’re in the market for a new phone—either for yourself or someone else—here’s my quick, no-jargon trick to spot a good phone from a bad one in about 30 seconds. When you’re in the store, grab the phone you like, open the Camera app, switch to Video, and check the maximum video resolution it can record. If it can do 4K video, that’s a yes—like, a massive yes. If it can’t record 4K, I’d seriously avoid it. The reason is simple: recording 4K video takes a pretty powerful phone. It usually means the CPU is up to the job, the software/OS is optimized properly, and there’s enough memory to keep everything running smoothly. And what that means for you (even if you’re not a “geek person”) is everyday stuff feels better—watching videos, checking email, browsing the web, and opening apps should be a nice experience. Pro tip: if you’re someone who records more serious video, look for 4K at 60fps (not 30fps). Most people don’t need that, but if you do, it’s a great quick check before you spend your money.
