If you use the phone while charging, handle the phone carefully since the cable or adapter is connected.
If you make/receive a call while charging, the charging may temporarily be interrupted.

other battery consuming operation.
IMPORTANT BATTERY CHARGING INFORMATION
Charging a very low battery
The battery's charge continues to drop after the low battery warning is displayed. In extreme cases where the battery is left uncharged for some
considerable time after this warning, a trickle charge is used to slowly top-up the battery to the safe level at which the fast charging can begin. The
phone can be in trickle charge for a few minutes before the fast charging starts.

Standby and talk times

Your phone works closely with the network you are using to provide the services you need, and the standby and talk times achieved will depend on how
you use the phone and choices made by the network operator.
In particular, factors such as your location within the network, the frequency at which this location is updated, the type of SIM card you have, your
reception of area messages or cell broadcast messages and the use of full rate or enhanced full rate speech, will affect both standby and talk times.
