To save and extend battery life, follow these steps:
Lower screen brightness and backlight duration
Most Android devices come with high resolution touch screens. This is one of the biggest drains on your battery.
To lower the brightness and duration, see Screen & keyboard: Samsung Galaxy S Relay 4G
Note: Some devices have the option for ‘Automatic Brightness’. This brightens and dims the screen based on your current environment.
Turn off Bluetooth, GPS, Wi-Fi, and Portable Wi-Fi hotspot when not in use.
All of these features will frequently search for connections in the background while you aren’t using them.
Note: These settings can be accessed quickly by using the Power Control widget. To add this widget, touch and hold an empty space on the Home screen, touch Widget, and touch Power Control.
If Wi-Fi is available, use it: Using Wi-Fi not only saves your mobile data usage, it also can be a more power-efficient way to use data instead of using your mobile network.
Change application sync settings
Keeping a constant feed from your social networks and e-mail accounts can cause your phone to be constantly interacting with the mobile network. Reducing the frequency that applications and e-mail accounts update can preserve battery life.
Turn off automatic synchronization and sync your e-mail and calendar manually. To change these settings see Internet & data: Samsung Galaxy S Relay 4G..
Turn off Background Data.
Aside from registered accounts with Google and T-Mobile Contacts Backup, your downloaded applications frequently update and can rapidly drain battery life. If the option is available, reduce the sync frequencies for these applications.
Minimize use of third-party applications:
Using applications can enhance your phones functionality, but they can also use up valuable battery life – especially if they keep your screen on, or require a data connection. Some applications are best used when the device is plugged in.
Note: If you battery life decreases significantly in a short period of time – consider any recent downloads that may have started the problem, and uninstall them.
Toggle from 4G to 2G
Our 4G network gives you faster data, but can also use more battery, especially if the 4G signal is weak. If you aren’t using data, leave your phone on 2G until you need it again. You will still be able to make and receive calls and browse the web at slower speeds while on 2G.
To change this setting, see Connections & network: Samsung Galaxy S Relay 4G.
Update to the Latest Software
Always make sure your device has the latest software version available. Device manufacturers and Google will release updates to the device operating system, often improving battery life as one of the benefits.
To check for system updates see Software versions & updates: Samsung Galaxy S Relay 4G.
Let it sleep
Be sure to put your phone into a sleep or standby mode when the device is in a pocket, case, or purse. Putting the device into sleep mode will keep you from unintentionally activating applications or illuminating the screen.
On most devices, this is done by tapping the power key.
Leave it plugged in
Your device should have a Lithium-based battery which means that leaving it on the charger will not damage the battery, even if it is already fully charged. Take advantage of AC power sources when they are available at home or at work for extended periods of time.
You should only use chargers that are approved by the manufacturer.
Calibrate the battery meter
Close battery-intensive programs, such as the Camera, when you are done using them.
Third-party applications may also drain the battery quicker.
If battery life diminishes significantly after installing applications from the Play Store, perform the following to determine the application causing the problem:
