Sony phones: My battery runs out quickly

Disable all data connections over mobile networks to save power when you’re not using the Internet. Doing so does not prevent your phone from transmitting data over other wireless networks.

From your Home screen, tap the "Settings" icon.
Find and tap "Settings" > "Data usage".
To turn data traffic on or off, tap the on-off switch beside "Mobile data traffic" accordingly.

You can also turn data traffic on or off by marking or unmarking the "Mobile data traffic" checkbox under "Settings" > "More…" > "Mobile networks".

Lower the screen brightness level.

1. From your Home screen, tap the "Settings" icon.
2. Find and tap "Settings" > "Display" > "Brightness".
3. Drag the slider to adjust the brightness.
4. Tap "OK".

Turn off your phone or activate "Airplane mode" if you are in an area with low network coverage. Otherwise, your phone repeatedly scans for the giffgaff network, which reduces your battery life.

1. From your Home screen, tap the "Settings" icon.
2. Find and tap "Settings" > "More…."
3. Tick the "Airplane mode" checkbox.

You can also press and hold down the power key and then select "Airplane mode" in the menu that opens.

Add the Quick settings widget to your Home screen
Turn off GPS, Bluetooth and Wi-Fi when you don’t need these features. You can turn them on and off more easily by adding the "Quick settings" widget to your Home screen.

1. Tap and hold an empty area of your Home screen.
2. Tap "Widgets" > "Tools".
3. Tap and hold the "Quick settings" widget, then drag it to an empty area of your Home screen.

Activate STAMINA mode
Use STAMINA mode to minimise battery consumption when the screen is inactive.

1. From your Home screen, tap the "Settings" icon.
2. Find and tap "Settings" > "Power management".
3. Tap the round icon next to "STAMINA mode", then tap "Activate".

Increase synchronisation intervals
Increase the synchronisation interval for your email, calendar and contacts.

1. From your Home screen, tap the "Settings" icon.
2. Tap "Email", then tap the "Menu" icon.
3. Tap "Settings" and select an email account.
4. Tap "Inbox check frequency" and select an interval option.

To access the battery usage menu
Check the battery usage menu in the phone to see which applications use the most power.

1. From your Home screen, tap the "Settings" icon.
2. Find and tap "Settings" > "Power management" > "Battery".

Additional tips:

• Close and exit applications that you are not using.
• Use a headset instead of speakers. A headset consumes less battery power than the phone’s loudspeakers. 
• Disable any live wallpaper
