Battery Lifetime Test Procedure

Web Site Measurement Procedure Notation Criteria

※ Important notice: The battery lifetime changes according to the device setting method and method of use. In reality, the results can be different from the actual time used, depending on the network connection status and constituents. Please note that the explanation relating to the measurement of each test item refers to the stated hours of smartphone set use.

A. Talk time

The talk time test was conducted in a lab environment with a simulated network.

The testing proceeded using the development stage prototype and software. We measured the time related with battery capacity by measuring current consumption, after the device was connected.

As regards talk time, it can end up being different from the actual time used, depending on the network connection status and function setup, signal strength, noise and other elements.

Specific tests can produce different results, depending on the device.

B. Audio play time

The audio play time test was conducted in a lab environment with a simulated network.

The testing proceeded using the development stage prototype and software. We measured the time related to battery capacity by measuring current consumption while playing MP3 files (192kbps) on the mobile unit (with the LCD turned off), and earphones connected to the device (or Bluetooth earphones if 3.5 earphones are not supported). We used standard playback files made by Samsung.

As regards audio playback time, it can end up being different from the actual time used, depending on the network connection status and function setup, signal strength, noise, audio file type and other elements.

Specific tests can produce different results, depending on the device.

C. Video play time

The video play time test was conducted in a lab environment with a simulated network.

The testing proceeded using the development stage prototype and software. We measured the time related to battery capacity by measuring current consumption after playing a video file (720p) that inserted into the device, and earphones connected to the device (or Bluetooth earphones if 3.5 earphones are not supported).

We used standard playback files made by Samsung.

As regards video playback, it can end up being different from the actual time used, depending on the network connection status and function setup, signal strength, noise, video file type and other elements.

Specific tests can produce different results, depending on the device.

D. Internet usage time

The internet usage time test was conducted in a lab environment with a simulated network.

The testing proceeded using the development stage prototype and software.
We measured the current draw while connected to the web and calculated the battery power to usage time of the device.

As regards internet use time, it can end up being different from the actual time used, depending on the network connection status and function setup, signal strength, noise and other elements.

Specific tests can produce different results, depending on the device.
