OPPO A 6x 4G vs TCL 4042 S
Our Verdict: The OPPO A 6x 4G has the bigger battery of the two, 6500mAh against 1500mAh, though real-world battery life depends on more than capacity, and the A5 2020 6x 4G has the stronger screen, bigger at 6.8" against 2.8" and sharper at 256 PPI. The TCL 4042 S is the lighter phone at 111g against 210g, and only the A5 2020 6x 4G has a water-resistance rating (IP64); the 4042 S has none. Get the A5 2020 6x 4G if those extras are worth it to you; otherwise the 4042 S covers the basics for less.
The 4042 S is the cheaper one to own: around £188 over a typical contract, £67 less than the A5 2020 6x 4G.
