Test the power supply voltage for the equipment under test nominal voltage. High voltage: 4.2 V. Low voltage: 3.6 V. normal voltage: 3.8 V Standby current≤10mA  

3

On current test Set up in the phone call connected, the current consumed when keep communication Normal temperature humidity conditions: temperature: 15 ℃,-35 ℃, relative humidity: 20%-75%; Limit temperature humidity conditions: temperature: - 10 ℃ - + 55 ℃ in the process of test, the power of the equipment to be tested by the test power instead. Test the power supply voltage for the equipment under test nominal voltage. High voltage: 4.2 V. Low voltage: 3.6 V. normal voltage: 3.8 V According to the design requirements  

4

Backlight current test Mobile phone in standby or testing mode Open the backlight (LCD backlight and The keyboard backlight) the backlight itself The current consumption of the Normal temperature humidity conditions: temperature: 15 ℃,-35 ℃, relative humidity: 20%-75%; Limit temperature humidity conditions: temperature: - 10 ℃ - + 55 ℃ in the process of test, the power of the equipment to be tested by the test power instead. Test the power supply voltage for the equipment under test nominal voltage. High voltage: 4.2 V. Low voltage: 3.6 V. normal voltage: 3.8 V ≤200mA,or according to the nature of backlight, models, types of varies。  

5

Buzzer current test Test the bell or the music is set to the most When the volume (loudness), buzzer Pronunciation when consumed by electric current Normal temperature humidity conditions: temperature: 15 ℃,-35 ℃, relative humidity: 20%-75%; Limit temperature humidity conditions: temperature: - 10 ℃ - + 55 ℃ in the process of test, the power of the equipment to be tested by the test power instead. Test the power supply voltage for the equipment under test nominal voltage. High voltage: 4.2 V. Low voltage: 3.6 V. normal voltage: 3.8 V According to the design requirements  

6

Vibration current test The current consumed by the machine rotates when the  phone in vibration Normal temperature humidity conditions: temperature: 15 ℃,-35 ℃, relative humidity: 20%-75%; Limit temperature humidity conditions: temperature: - 10 ℃ - + 55 ℃ in the process of test, the power of the equipment to be tested by the test power instead. Test the power supply voltage for the equipment under test nominal voltage. High voltage: 4.2 V. Low voltage: 3.6 V. normal voltage: 3.8 V ≤90mA,Or depending on the type, the motor type and the driving circuit and slightly different  

7

Received signal strength test Testing  mobile receiving weak signals ability Mobile phone RF interface or duplex output, and from the measuring connection, from adjust measuring BS/RX LEV broadcast control channel, watch mobile phone signals, and cell phone signal showed decrease from high to low in this article, record every article signal when the cell phone reception level, to mobile phone received signal strength If no  any signal or BCCH Level is unusual, is not qualified  

8

Battery capacity test Test battery in the case of charging and discharging capacity in the rating (MA/H) between the variables Dispatch high-speed programmable power supply output voltage 4.2 V, and to give fake batteries, and then work with fake batteries for mobile phones to provide power supply, and from high to low adjust the output voltage of high speed programmable power supply, battery shows, record the battery per this article shows the decreasing when the display of voltage, to test the voltage and the article shows the match The voltage and display correspond (note: the standard voltage of 3.7 V and battery power should be at least 1 to 2 frame)  

9

Ringing sound level test test whether phone ringing sound level reach the standard specifications and design requirements Cell phone ringtone db test randomly selected 5 cell phone in a quiet environment for testing. Test, cell phone with a SIM card is in standby mode, to prompt to set it to ring pattern, ringing bells, the largest flow rate to close the cover, placed on the hard wooden boards. Sound level meter with mobile phone in a straight line, located 30 cm, and with mobile phone in the plane into a 45 degree Angle. Use another mobile phones call under test, in test cell phone ring, observe the reading on the sound level meter, namely for the mobile phone under this kind of ring the bell db value. Test each of every kind of mobile phone ringtone db value >75dBA

 MP3/MP4 volume test Test whether MP3/MP4 level reach the standard specifications and design requirements 1、Mobile phones play the test signal being measured. Test signal for the specified music files。
2、Used to satisfy IEC651 Type0/1 requires measurement microphone distance along the loudest strong direction measured 30 cm fixed phones。
3、In the audio signal sampling, signal cycle of 48 KHZ sampling frequency
4、Use audio analyzer for signals with Hanning window and 4096 point FFT, Overlad was 75%。
5、 Using A weight of 200 hz ~ 3500 hz within the scope of the signal is calculated
