Instrument Settings:
Voltage: 3.8 Volt
Limiter: 2A

Note: During the calibration the accurate voltage from the VBATT must be within ±0.015 V. If
this is not fulfilled it will result in a faulty calibration. (For more information about
recommended power supply units, see the Repair Tool Catalogue on CSPN under the Mechanical
level. The Power Supply Channel 1 VBATT must allow reverse current.

Note: Maximal cable length between the Power Supply Channel 1 VBATT and the dummy
battery must be maximum 1m. The cable must have a capacity for at least 16A.

Note: It is very important to follow instrument settings instructions when performing the
Battery Calibration Test.

Current Consumption Test

Step 1:

Insert Local SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected to
Power Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.

Measure the current when the Phone is off. Check the current consumption at Power Supply Channel 1
VBATT.

Picture 1

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:

Start the phone:
Measure the deep sleep current max 6mA typical between 0-3mA.

Make sure that the operator is running with deep sleep. (This operation can be switched off by operator if
the network is busy).

If the phone is using more than 6mA, then go to EMMA III and perform Software Update Contents Refresh
(SUCR).

Step 3 with Mobile Phone Tester Instrument

Insert Test SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected to Power
Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.

Use the Mobile Phone Tester Instrument in signalling mode directly connected to the phone with the RF
Connector or use Shield Box if not possible. Phone Display must be on during these tests to get correct
current measurements.

Perform Radio TX measurements at GSM and WCDMA Band and compare the result with limits according to
the text below.

Transmitter current 850 MHz at Ch: 128 power level 5. Typical 400mA
Transmitter current 900 MHz at Ch: 1 power level 5. Typical 385mA
Transmitter current 1800 MHz at Ch: 512 power level 0. Typical 365mA
Transmitter current 1900 MHz at Ch: 512 power level 0. Typical 365mA
Transmitter current WCDMA BAND I Low RX Ch: 10562 at 23dBm output power Max 850mA

TROUBLESHOOTING

If the current consumption is not correct, the fault could be fixed by running SERP calibration if not then go
to GSM and WCDMA Network problems TRS guides.
If the current consumptions are equal to test limits then go to Charging Test.

- Power Supply Channel 2 DCIO/SEPI: Instrument settings Voltage: 5V, Limiter: 2A

This test should be preformed in 3 steps:

Step1:

Measure the voltage at the Backup capacitor by using Fault Trace SW- Logic - ADC Values –
Read ADC Value (Reading 1).

Step2:

This step should be done 30 seconds after Step 1. Measure the voltage at the Backup capacitor
by using Fault Trace SW - Logic – ADC Values - ADC Channels – Read ADC Value
(Reading 2).

Step3:

Compare the difference between Reading 1 and Reading 2 with the reference table below. If the
Reading 1 value is between 50 and 680 go to Interval 1, if between 681 and 800 go to Interval
2, if between 801 and 880 go to Interval 3 and compare with the Reading 2 – Reading 1 Min and
