Charging

The best way to charge your phone's battery is to use the charger supplied with the phone. The charger or the phone (depending on the make of the phone) will care for the battery far more carefully than some of the third-party chargers on the market.

This is a typical example - if you don't want the technical bit, skip to the next paragraph:
The charger of a Nokia phone gives 12v DC maximum, current-limited to 700mA. This is supplied to the phone, which checks the battery capacity (reading a labelling resistor build into the battery) and temperature (using a temperature sensor built into the battery). If the battery is too hot or cold, it refuses to charge it. As the battery is charged at a steady 700mA, the phone monitors the voltage, which rises steadily till the battery is full, then rises more slowly when the battery is full. At this point, the phone switches to trickle-charging, which involves switching the current on and off in short bursts, which helps prevent formation of whiskers within the cells (too technical to go into here). All the time, the phone checks the battery temperature, because if the cell gets hot, that's a sign that it is full and charging should be stopped
