Environmental Specifications

Normal and extreme voltages

Following voltages are assumed as normal and extreme voltages for used battery:

Table 1: Normal and extreme voltages

ADC settings in the SW might shutdown the phone above this value.

During fast charging of an empty battery, the voltage might exceed this value. Voltages between

4.20 and 4.60 might appear for a short while.

Temperature conditions

• Operational temperature range (all specifications met within this range):

–5°C.. +55°C (stationary use)

• Functional temperature range (reduced performance):

–30°C.. +70°C

• Storage temperature range:

–30°C.. +85°C

Temperatures at –10°C, +25°C and +55°C are used for the cpk analysis.

The baseband module complies with the SPR4 Operating Conditions.
