The antenna switch is mechanical, whenever you plug in the bottom connector, the
handset will switch to its external antenna.
5.3 Power Supply Concept
The S6 has two main power inputs (see Blockdiagram):
1) Battery Voltage (3.6 Volts) connected at the battery contacts
2) Charging Voltage (6.5 Volts) delivered by
a) The plug-in charger at the charging plug
b) The desktop charger (using the charging contacts at the bottom of the phone)
Since the battery voltage is supplying the power supply asic, it is always needed to
operate the phone. You cannot switch on the handset if the battery voltage is not
Blockdiagram S6 Power Supply
From the 3.6 V battery voltage, all other supply voltages of the S6 are derived,
controlled by the power supply ASIC.
The RF module needs 6.4 V for its PA, this voltage is generated by a step-up
The logic module uses 2.8 V, generated by a simple linear regulator.
