Understanding Mobile Battery Discharging Time
Mobile phone batteries (typically lithium-ion or LiPo) discharge over time due to usage, standby power, and environmental factors. The "discharging time" generally refers to battery runtime—how long the battery lasts on a single charge before needing a recharge. This varies widely based on the phone model, battery capacity, apps running, screen brightness, and more. On average, a modern smartphone lasts 6–12 hours of active use or 1–2 days on standby/light use.
Key Factors Affecting Discharge Time

Battery Capacity: Measured in milliamp-hours (mAh). Higher mAh = longer runtime (e.g., 4,000–5,000 mAh is common).
Power Consumption: Apps, GPS, video streaming, or high brightness drain faster.
Age and Health: Older batteries lose capacity (e.g., 80% after 500 cycles).
Temperature: Heat speeds up discharge; ideal is 20–25°C (68–77°F).
Self-Discharge: Even idle, batteries lose 1–5% per month due to chemical reactions.

How to Calculate Battery Discharge Time
For a rough estimate, use this formula:
Discharge Time (hours) = (Battery Capacity in mAh × Battery Voltage × Efficiency) / Device Power Consumption in mW

Battery Voltage: Typically 3.7–3.85V for mobiles.
Efficiency: 80–90% (0.8–0.9) to account for losses.
Power Consumption: Check your phone's settings (e.g., 5–10W for moderate use).

Example Calculation:

Battery: 4,000 mAh at 3.7V.
Efficiency: 0.85.
Consumption: 2,000 mW (e.g., browsing + screen on).
Time = (4,000 × 3.7 × 0.85) / 2,000 ≈ 6.3 hours.

For more precision, use the C-rate method (common for lithium batteries):

C-rate is discharge current relative to capacity (1C = full discharge in 1 hour).
Time = 1 / C-rate (e.g., 0.5C = 2 hours).

Tools like Apple's Battery Insights or Android's Battery Usage stats can track real-time drain.
