Current Consumption Test

Step 1:

Insert a Local SIM Card and use the phone with the Signalling SW (SSW). Use Dummy Battery connected to Power Supply Channel 1 (VBATT). Instrument settings: Voltage: 3.8 Volt, Limiter 3A.

Note! The Dummy Battery should have approximately 27K Ohm resistance between

GND and BDATA.

Measure the current consu m pt i on whe n th e Phone is turned off. Take a note of the current consumption at Power Supply Channel 1 (VBATT).

The Current consumption in off mode should be less than 1mA. If more than 1mA go to Dead Phone Problems part 1 TRS guide.

Step 2:

Turn the Phone On: Measure the deep sleep current max 6mA typical between 0-3mA. Make sure that the

operator is running with deep sleep mode.

Note! This operation can be switched off by operator if network is busy or heavily-loaded.
