OPPO A 6 Pro vs TCL 4042 S

Our Verdict: OPPO A 6 Pro pulls ahead for screen resolution thanks to 1080 x 2372 resolution rather than 240 x 320, plus 7,000 mAh compared with 1,500 mAh. There is still a sensible reason to pick TCL 4042 S: a 111g body against 185g matters when you want the lighter phone. In short, OPPO A 6 Pro is for a higher-resolution display; TCL 4042 S is for a lighter handset.

Over a full contract, the 4042 S works out around £188 all-in, about £173 less than the A5 2020 6 Pro.
