※ 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.

The talk time measurement test was carried out by taking into consideration the telecommunications company and area. It took place in a lab environment replicating the (LTE/WCDMA/GSM/CDMA) network. We made a call in the environment, setting the channel and band.

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.

The audio playback measurement test was carried out by taking into consideration the telecommunications company and area. It took place in a lab environment replicating the (LTE/WCDMA/GSM/CDMA) network. We played an audio file in the environment, setting the channel and band.

The testing proceeded using the development stage prototype and software. We measured the time related with battery capacity by measuring current consumption after playing Mp3 files (192kbps) through the mobile unit (with the LCD display turned off). The playback files were 10 songs selected from the 2011 global chart.

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.

The video playback measurement test was carried out by taking into consideration the telecommunications company and area. It took place in a lab environment replicating the (LTE/WCDMA/GSM/CDMA) network. We played a video file in the environment, setting the channel and band.

The testing proceeded using the development stage prototype and software. We measured the time related with battery capacity by measuring current consumption, after playing a video file (720) that inserted into the device.

We measured a file selected from the global box office list of 2011, in 'avi' format, used very frequently by different multimedia, and with a 720p resolution.

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.

The Internet use time measurement test was conducted in a (WCDMA/LTE) network environment.

The testing proceeded using the development stage prototype and news articles were searched for and accessed via the Web. All settings were used to set the default and measured without turning on Wi-Fi.

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.
