Compare Mobile Phones Side-by-Side

This is a very close comparison, because Oppo has kept the core experience almost the same: both phones give you a large 6.75-inch 120Hz display, 4GB of RAM, and big batteries. The difference is mostly about what you value more after the basics are covered.

The OPPO A6c is the one to pick if battery life is your main priority. Its 7000mAh cell gives it a clear advantage over the already-large 6500mAh battery in the Oppo A6x 4G, so it makes more sense for heavy callers, video watchers, or anyone who hates charging often.

The Oppo A6x 4G is slightly more reassuring if you care about the chipset side, simply because it uses a Qualcomm processor rather than Unisoc. Without more detailed performance data, it is hard to call it faster, but Qualcomm-powered budget phones are usually the safer bet for everyday reliability and app compatibility.

For most buyers, I’d lean toward the OPPO A6c for the bigger battery. Pick the A6x 4G only if the Qualcomm processor matters more to you than maximum endurance.
