- Final Considered Value with 25% margin: 1134 mAh
- Network quality alone can cause up to a 7x difference in battery life.
Key Factors (summary)
1. Network Quality (Most Critical – Up to 7× Impact)
Poor network signal is the primary cause of reduced battery life. Devices consume more power when retrying transmissions or maintaining weak connections.
| RSSI Range | Signal Quality | Expected Life |
|---|---|---|
| 53–73 | Excellent | ~36 months |
| 75–93 | Good | ~26 months |
| 95–109 | Low | ~5 months or less |
- Lower RSSI values indicate stronger signals.
- If RSSI exceeds 95, reposition the device to improve connectivity.
2. Configuration Settings
| Configuration | Battery Impact |
|---|---|
| 1 Image + 1 Ping in a day | Best |
| 2 Images in a day | Moderate |
| 2 Images + Ping in a day | Highest consumption |
- Configuration impact is minimal under excellent signal but significant under poor signal.
3. Device Orientation
Device orientation directly impacts the battery’s recharging efficiency since the OPV panel is located on the backside of the device.
| Orientation | Impact on Battery & Charging |
|---|---|
| Horizontal Mounting | Allows maximum indoor light exposure and efficient battery recharging. |
| Vertical Mounting | Limits indoor light on the OPV panel, reducing or preventing effective recharging. |
4. Lighting Conditions
| Lighting | Impact |
|---|---|
| 400+ Lux | Minimal |
| Below 250 Lux | Noticeable drain |
- Lighting affects battery moderately but is less critical than network quality.
How to maximize battery life
Priority 1: Ensure Strong Network Signal
- Test RSSI before installation. Install devices where RSSI < 75.
Priority 2: Optimize Configuration
- Use 1 Image + 1 Ping whenever possible.
- Use 2 Images only if necessary.
- Avoid taking more than 2 Images unless required.
Priority 3: Choose Installation Location Carefully
- Maintain 400+ Lux lighting.
- Avoid temperature extremes and interference.
