📊 How 2600mAh Translates to Real-World Usage
| Usage Scenario | Estimated Playtime per Full Charge |
|---|---|
| Low volume (background music) | ~15–20 hours |
| Medium volume (typical listening) | ~10–15 hours |
| High volume (party mode) | ~6–8 hours |
| Standby mode | ~30+ days |
Estimates based on typical Bluetooth speaker power draw of 0.5–2W. Actual results may vary by speaker model and volume level.
🔄 Cycle Life Explained
A “cycle” equals one full discharge followed by a full recharge. The ASOL 1S1P maintains ≥80% capacity after 500 cycles under standard test conditions (0.2C discharge, 0.5C charge at 25°C).
Partial charges do not consume full cycles — so topping up after each use actually extends the battery’s effective lifespan. With typical usage (1–2 hours daily), this translates to well over 2 years of reliable service.
