Fitbit Charge 3 Full Review
At first glance, the Charge 3 looks quite similar to the Charge 2: a similar vertical black and white screen and almost the same overall shape and size. But if you look more closely, the guys completely redesigned their new product. She got a new aluminum body and Gorilla Glass 3 protective glass for her screen. The display now supports a wider color gamut - in addition to simple black and white colors, it is complemented by grayscale, and its active area has increased by 40 percent compared to the Charge 2.
The Charge 3's body is water resistant (water pressure resistant up to 50 meters), allowing the tracker itself to track your swim, in addition to monitoring other exercises that Fitbit has added in the past. A more accurate heart rate sensor has also been added, and a new SpO2 sensor that measures blood oxygen levels, which was previously only found in the company's smartwatches. In terms of battery, the Charge 3 now offers up to seven days of battery life on a single charge, up from five days on the Charge 2.
The physical button since Charge 2 has also been replaced by a new inductive counterpart, similar in action to later iPhones. At its core, it has a built-in vibrating mechanism that simulates pressing when touched with a finger. According to the developers, switching to such a button helped save internal space and improved the overall protection of the case from water. The Fitbit Charge 3 doesn't have built-in GPS - according to the guys, this was a deliberate compromise to improve its design, price and battery life. I think this is quite normal, considering that almost any modern bracelet works in conjunction with a phone.
The developers have added several new apps to the Charge 3, including an alarm clock, timer, weather forecast and calendar.
