Samsung Galaxy A51 vs Samsung Galaxy A70

Our Verdict: Comparing Samsung Galaxy A70 and Samsung Galaxy A51, the choice mostly comes down to battery size versus camera hardware. The A70 gives you a larger 4,500 mAh battery and a 4.4/5 expert-review average from 9 reviews, while the A51 is more appealing for a higher-resolution 48MP rear camera. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Choose the A70 for battery size; choose the A51 if camera hardware matters more.

If you'd rather pay up front, the A70 is the cheaper buy at £115 SIM-free.
