Mobile phone battery capacity detection method
1. Check battery capacity using special battery capacity test software for mobile phones.
2. On the condition of ensuring that the testing process is constant current, select a resistance similar to the resistance of the mobile phone to be tested and connect it in series with the ammeter, and then discharge the fully charged. (4.2 V) until it ends at 3.7 V. Measure the current and record the time. For example, the recorded current is 200 mA and the discharge time is 4 hours. The battery capacity is then 200X4=800mAh.
3. Submit it to a professional testing service for testing.
How to calculate the battery capacity of a cell phone?
The charging method of lithium batteries is the voltage-limited cross-current method, and the charging current is generally set at0.2 C. The charging and discharging current is generally used as a reference, and C is the value corresponding to the battery capacity. Battery capacity is generally expressed in mA. For example, the battery capacity of L600 is 1800 mAh and the corresponding C is 1800 mA. 0.2C is equal to 240mA.
