As smart wearable applications expand into healthcare, elderly care, industrial safety, and long-term monitoring scenarios, ultra-low power design has become the key factor for product success.
From 30-day
battery life smartwatches to coin-cell smart rings with 3–month standby,
brands now require deeper engineering-level optimization rather than simple
hardware stacking.
Shenzhen Geyan Technology Co., Ltd. provides complete OEM/ODM ultra-low-power wearable solutions for smartwatches, smart bands, and smart rings.
A 30-day battery life smartwatch requires multi-dimensional optimization at PCB, firmware, and system levels:
· Ultra-low-power MCU & BLE architecture
· Dynamic power domain partition
· Sensor power gating technology
· AMOLED/TFT adaptive refresh rate
· Intelligent sleep and wake-up firmware
Geyan’s optimized PCB and firmware frameworks enable most custom smartwatch projects to reach 20–30 days of daily usage and 45+ days standby.
For slim and lightweight smartwatch designs, 200mAh battery capacity is often the structural limit.
Our optimization strategies include:
· High-efficiency PMU power paths
· BLE low duty-cycle broadcasting
· Motion-triggered sensor wake-up
· Deep sleep firmware architecture
· Battery curve calibration algorithms
These allow even compact smartwatches to deliver stable 2–4 week runtime without sacrificing health tracking accuracy.
Long standby time is essential for elderly care, medical, and enterprise wearable projects.
We apply:
· RTC domain isolation
· Secondary ultra-low-power coprocessor control
· Event-based firmware scheduling
· Minimal background BLE advertising
This enables 60+ days standby smartwatches that remain always connected and reliable.
Smart rings are space-limited and extremely power-sensitive.
Our low-power smart ring PCB design focuses on:
· Coin cell battery optimization
· Ultra-low leakage PMIC architecture
· Miniature SpO₂ & HR sensors
· Efficient BLE communication protocol
Delivering continuous health monitoring with multi-week operation per charge.
For outdoor, military, and remote region applications, Geyan offers solar-powered smartwatch OEM solutions:
· Integrated photovoltaic charging layers
· Smart charging path management
· Ultra-low-power always-on operation
Allowing semi-permanent operation with minimal charging requirements.
Our coin-cell BLE smart ring platforms support:
· 3–6 months standby
· Bluetooth 5.0+ low energy stack
· Secure data transmission
· Mobile APP & cloud connectivity
Ideal for sleep tracking, wellness monitoring, and medical pilot programs.
For large-scale distribution programs, we provide smart band designs with up to 3-month standby, combining:
· IP68 waterproof PCB layout
· Ultra-low-power firmware framework
· High durability battery and casing design
