Fed up of constantly charging and re-charging your smartphone? This mega saving on the mega long-lasting Samsung Galaxy M31 could be your saving grace this Amazon Prime Day.

As part of Amazon’s annual Prime Day promotion, you can pick up the Galaxy M31 for just £200 , an 18% saving on its usual price of £245.

For context, that’s comfortably the best deal we’ve seen on this handset since its release date back on 4 March, and also makes it one of our favourite deals you can pick up on a smartphone of any kind this Prime Day.

And this isn’t just any budget smartphone. Put simply, the Galaxy M31 has the largest battery of any handset, Samsung or otherwise, that we’ve ever tested here at Expert Reviews. Its 6,000mAh battery puts previous record-holder the Lenovo P2’s 5,100mAh equivalent in the shade.

In our continuous video-playback test, the budget handset lasted a whopping 30hrs 20mins with all data connections switched off and the brightness set to 170cd/m² – that’s over 90 minutes more than the aforementioned P2 and the most impressive result we’ve ever seen.

Even if battery life doesn’t sit atop your list of requirements when it comes to purchasing a wallet-friendly smartphone, there’s still plenty to love about the Galaxy M31. It has an excellent display, as well as an impressive quadruple-camera setup which includes a 64-megapixel sensor – among the very best you’ll find at this price.

That was enough for us to award it a five-star review and Best Buy award , and it now sits high up on the list of our favourite budget smartphones .

So, if you want to own a more-than-handy smartphone that will keep going for a smidge over three days between charges, there’s never been a better time to buy.

And if you’re not already a Prime member but don’t want to miss out on this saving, don’t fear: you can always sign up for a 30-day free trial, which you can cancel at any time .
