Both the Smartphones are awesome at their own price ranges. Looking at the hardware on might feel that M51 is a better choice when compared to Galaxy A71, but there are a whole lot of features that are only available in Galaxy A71 which cannot be mentioned in these columns. That’s the reason why Galaxy A71 is priced higher than Galaxy M51. Galaxy A71 has a better UI, sound quality and customization features whereas Galaxy M51 has a better battery life when compared to Galaxy M51. The processor is the same in both the smartphones and their is no difference between SD 730 and SD 730G processor. But as there is a price difference of Rs. 2500 between the 8GB|128GB variants of both the smartphones, the user can choose to buy Galaxy A71 if his budget allows him to. Galaxy M51 is also available at Rs 24,999 for the 6GB|128GB variant in which the user gets all the features except a bit more RAM. So a person whos budget is below 25K Rs must go for Galaxy M51 and a person whose budget is 27K Rs can buy Galaxy A71 by adding the extra 2500 Rs taking into account the plus points that the smartphone holds when compared to M51.
