Sony Xperia 10 III 5G vs Sony Xperia 10 IV
Our Verdict: These are two phones from the same range, with the Xperia 10 III 5G sitting above the Xperia 10 IV. There's more battery in the IV 5G, 5000mAh to 4500mAh, which should mean longer between charges in day-to-day use, and the III 5G has the stronger screen, bigger at 6.5" against 6" and sharper at 643 PPI. Storage goes higher on the III 5G, up to 256GB against 128GB, and the IV 5G is the lighter phone at 161g against 186g. Only pay up for the III 5G if you'll use what it offers; if not, the IV 5G makes more sense.
If you'd rather pay up front, the IV 5G is the cheaper buy at £237 SIM-free.
