Editor's Rating

Which Should You Buy?

First of all, it’s important to state that from the design, features, and otherwise, the Ionic is a more comprehensive smartwatch (if I can also call the Charge 4 a smartwatch, though looks more like a smartband). The Ionic is of a higher quality which you can see from the design. While it has a more durable aluminum case and Corning Gorilla Glass 3, Charge 4 case is made of resin. Similarly, it also has a brighter and more colorful LCD display compared to the monochrome LCD of Charge 4. In other words, I think it’s right to say that the Ionic is a better smartwatch with more features like music storage and up to 5 days long battery life

Charge 4, on the other hand, is way cheaper, yet has lots of fitness tracking features in addition to the newly added Active Zone Minutes that allow you set target heart rate and has up to 7 days long battery life that allows you go longer from a single charge. I conclude by saying that, Charge 4 is better choice for you if you need a cheaper fitness companion.
