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.
