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 mobile data connections from the

Notification panel by dragging down the status bar. This setting does not prevent your

device from transmitting data over other wireless networks.

•

Turn off Bluetooth® and Wi-Fi® 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 mode 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.

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.
