- Battery Life and Charging Method. Rechargeable scales should last at least 6 months on a full charge. USB-C charging is more convenient than older micro USB ports.
- Metrics Provided. Basic scales often measure only weight and body fat, while advanced models include muscle mass, bone mass, visceral fat, and more. Choose based on your fitness goals and level of detail desired.
- Build Quality and Design. Tempered glass surfaces with sturdy construction last longer. Consider the size and weight if you plan to move it frequently. Larger displays and backlighting enhance readability.
