HONOR 400 Smart vs OPPO A 6 Pro

Our Verdict: For camera specs, the A 6 Pro has the 16MP front camera, so treat it as an advantage in hardware rather than a guaranteed photo-quality win. The A 6 Pro also carries the bigger battery at 7,000mAh, but battery life still depends on software and chipset efficiency. The display detail leans toward the A 6 Pro, rated at 397 PPI against 261 PPI. Buy the HONOR 400 Smart if its overall feature mix is central to the upgrade; buy the A 6 Pro if a sharper display carries more weight.

The A5 2020 6 Pro is the cheaper one to own: around £361 over a typical contract, £103 less than the 400 Smart.
