Compare Mobile Phones Side-by-Side

Based on the specs here, the vivo X500 has the clearer hardware edge. Both phones use a 6.59-inch display, MediaTek silicon, and 12GB of RAM, so the everyday performance gap is unlikely to be defined by memory or screen size. Where the vivo pulls ahead is in the two things you’ll notice over time: the smoother 144Hz refresh rate and the larger 7500mAh battery.

The Oppo Find X9+ is still strong on paper, and its 120Hz display is hardly slow. But with a smaller 7025mAh battery and no listed advantage in processor, RAM, or display size, it has less to argue with from the data provided. Unless the Oppo wins you over through factors not shown here — camera tuning, software, design, or price — the vivo X500 looks like the more practical pick for buyers who care about fluid scrolling, gaming responsiveness, and longer battery life.
