Compare Mobile Phones Side-by-Side

Between these two, the Oppo A6x 4G is the safer pick for most buyers. The displays are very close in spirit — both are large 120Hz panels — but Oppo pairs that with a slightly bigger 6500mAh battery and a Qualcomm processor, which is usually the more reassuring choice for everyday smoothness, app compatibility, and long-term reliability in this class.

The Poco C81 mainly makes sense if you simply want the biggest screen possible. Its 6.9-inch display gives you a little more room for videos, browsing, and reading, and the 6300mAh battery is still very large. But with the same 4GB RAM and a Unisoc chipset, it feels more like a budget big-screen phone than the stronger all-rounder.

If pricing is similar, I’d lean toward the Oppo A6x 4G. The Poco needs to be noticeably cheaper to become the smarter buy.
