How much is the current and voltage when charging the mobile phone battery

How much is the current and voltage when charging the mobile phone battery


Charger voltage is generally 5V, the 5V after charging circuit into 4. 2V, and then charge the battery
The charging current of different mobile phones and batteries is not necessarily the same. Generally, the slow charging current is 0.1C (for example, if the battery is 1000mah, the charging current is about 100mA)
