  • Absolute monster of a midrange

    Absolute monster of a midrange, hard not to recommend at this price point. There are definitely some compromises, though: the plastic back gets scratched easily, no optical image stabilization (although the electronic one does a great job with videos), no 60fps recording, OneUI core means you don't get secure folder, good lock and a couple more Samsung features and the vibration motor is just... ugh. Don't use it for typing for your own sanity's sake.
    But given this phone's screen, overall performance and the peace of mind that your battery is going to last you the whole day (if not up to 3) no matter how you use it (feel like spending the entire day playing CoD Mobile on high settings? Go ahead, the battery won't flatline on you), it's well worth it in my opinion.

    Positives
    • Absolutely mental battery life
    • SAMOLED+ screen
    • Reverse charging lets you use it as a powerbank
    • the SD 730G makes it fast and reliable
    • Lightning quick traditional fingerprint sensor
    • Slots for 2 sims AND a micro SD, plus 3,5mm jack
    Negatives
    • Plastic back that is a fingerprint and scratch magnet
    • OneUI Core means you miss out on some features
    • 60Hz Screen
    • Vibration motor feels terrible for typing

    Recognition of the Galaxy M51

    The M51 is perfect for young people and those who use 24 hours. Seeing its characteristics it is a PERFECTLY BALANCED AND VERY RECOMMENDED cell phone, Renocer that if they are strict in design is made of plastic but has a beautiful finish. I do not demand anything else, I love its 7,000mAh battery

    Positives
    • 7000mAh battery
    • Super amoled
    • NFC
    • Anyway what else !!!!
    Negatives
    • This phone for the price it has is not unbeatable
    • If you are looking for design, there are the high ranges of SAMSUNG.

    It's pretty good

    It is a mobile, to forget if the battery will reach us all day and is mobile if it offers it to you and the best thing that with that 7000 battery does not look heavy in the hand, then in general its cameras are not bad its screen is fine, its processor is fine, for me what I see weaker is the sound. This mobile is for people who do not demand so much

    Overall good, but the camera immediately let me down. Even better than the iPhone 7

    Recently bought, but I immediately noticed that the battery lost 20% when copying files from the old phone and downloading WhatsApp in less than an hour. So much for the 7000 mA. Not to mention the camera. The Nokia N95 also had better colors, it really disappointed me. Fingerprint reader works once yes and 5 no. Xionami mi 8 Pro has gesture for easy use. M51 no. And I've only been using it for one day.

What is a Ki score?
Ki is an automatic score based on the specifications and prices of devices. It is calculated using over 200 variables to rank smartphones, tablets and other devices from best to worst.
How do we calculate the Ki?

In this case, to determine the score we evaluate 5 general aspects:

  • Design and screen
  • Hardware and performance
  • Camera
  • Connectivity
  • Battery

Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.

Even a device objectively worse than another may have a higher Ki score if it has a better price.

Does the Ki score change?

The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
