Why 4G Smartwatches Still Dominate (2025 Update):
Most smartwatches today rely on 4G LTE, not 5G, due to unresolved technical and practical challenges:
Power Efficiency: 5G consumes 60-70% more energy than 4G. 5G RedCap to cut power, but this tech is still experimental.
Hardware Limitations: 5G requires larger antennas/modems, conflicting with compact designs.
Cost vs. Value: 5G modules raise production costs by 30-50%, yet benefits are minimal. Watches don’t stream HD video; 4G suffices for calls/messages.
Future Timeline: 5G watch (late 2025) will target niche outdoor users with satellite SOS. Mass adoption requires 2-3 years for cost reduction and ecosystem readiness.
Key Takeaway: 4G remains the practical choice for reliability, battery life, and affordability. 5G smartwatches are still in early adoption, with limited use cases and premium pricing.
