Sony Xperia 5 III 5G vs Sony Xperia 5 II 5G

Our Verdict: The Xperia 5 II 5G and Xperia 5 III 5G came out side by side, the III 5G as the top model and the lI 5G as the more basic one. The III 5G packs the bigger battery, 4500mAh against 4000mAh, which should mean longer between charges in day-to-day use. For most people the lI 5G does the job for less, and the III 5G isn't worth the premium here.

Buying outright, the lI 5G starts at £224 SIM-free.
