"Beginning in 2012, many smartphone manufacturers began to offer devices with dual-core processors, and not long after that, quad-core processors. In theory, the more processors, the faster, as they can divide up the work you’re asking the phone to do."

"A quad-core processor is faster than a single- or dual-core processor only when it’s running an application that’s been developed to take advantage of its abilities. Most applications today are still written for single- or dual-core processing, and while most of the time this simply means the quad-core’s extra power goes unused, there are other instances when the application performs better with dual-core processing power."

"...you may turn up your nose at perfectly fast devices running on dual-core chipsets, wondering if you should saddle yourself with something so "slow." After all, the more processing power, the better the phone, right?"

"In the end, your smartphone's internal performance boils down to more than the number of cores. Instead, it depends on a delicate balance involving everything from your base chip and batteries to your operating system, and even on the people who code your favorite apps."
