Improving battery performance

The following tips can help you improve battery performance:

•

Charge your device often. This will not affect the lifetime of the battery.

•

Downloading data from the Internet is power consuming. When you're not using the

Internet, you can save power by disabling all data connections over mobile networks.

This setting does not prevent your device from transmitting data over other wireless

networks.

•

Turn off Bluetooth® and Wi-Fi® connections when you don't need these features. You

can turn them on and off more easily from the Notification panel by dragging down the

status bar.

•

Use the STAMINA mode and Low battery mode features to reduce battery

consumption. You can select the power saving mode that best suits the way you use

your device. You can also customize the settings of each power saving mode.

•

Set your synchronization applications (used to synchronize your email, calendar, and

contacts) to synchronize manually. You can also synchronize automatically, but

increase the synchronization intervals.

•

Check the battery usage menu in your device to see which applications use the most

power. Your battery consumes more power when you use video and music streaming

applications, such as YouTube™. Some applications downloaded from Google Play™

may also consume more power.

•

Close and exit applications that you are not using.

•

Lower the screen display brightness level.

•

Turn off your device or activate the Airplane mode setting if you are in an area with no

network coverage. Otherwise, your device repeatedly scans for available networks,

and this consumes power.

•

Use a Sony™ original handsfree device to listen to music. Handsfree devices demand

less battery power than your device's own loudspeakers.

•

Keep your device in standby whenever possible. Standby time refers to the time

during which your device is connected to the network and is not being used.

•

Disable any live wallpaper.

Using STAMINA mode

Activate the STAMINA mode feature to pause your Wi-Fi® connection, data traffic and

several power consuming applications when your screen is inactive. When STAMINA

mode is active, you can still receive phone calls, and text and multimedia messages.

when your screen is inactive. Once the screen becomes active again, all paused

functions are resumed.

Estimating the standby time of your device

Standby time refers to the amount of time the battery can last when your device is

connected to the network but is not in active use, for example, to receive or make

phone calls. STAMINA mode, when activated, continuously evaluates the remaining

standby time, which can vary depending on how you use your device. STAMINA mode

is more effective in lengthening the standby time if you keep the screen of your device

locked. If you rarely lock the screen, you may not see much improvement in battery

performance.

When you use your device for the first time, the estimated standby time may not be accurate

since there is no previous usage history to estimate from.

To view the estimated standby time

Using Low battery mode
