How can I extend my battery life?
Your particular usage will affect how long you can go before recharging your battery. Navigating, playing games, surfing the Web, making calls and texting all use energy. You can install and use a wide variety of applications on your device, and each application has its own characteristics.
Thus your experience may vary day to day, depending on how you use your device.

Depending on your preferences, you can tailor how your device behaves by using some of the following tips:
- Charge each night so you start the day fully charged and ready to go.
- You can see what subsystem, component, or application is using the most power: Touch > Settings > Battery
- If you are stationary in an area in which there is low or no cellular signal, it may be prudent to enter airplane mode unless you must be able to (try) to make or receive calls or texts. Doing so will prevent the phone from increasing power output in an attempt to connect to the weak signal.
- When setting the phone down after use, quickly press the power key to turn the display off.
- Set Screen timeout less then 1 minute: From the Settings menu, scroll down and tap on Display and then tap on Sleep to select a faster time-out.
- Turn off applications actively using GPS, such as navigation applications when you no longer need them. It is easy to forget to 'end navigation' when you reach your destination. Swipe down from the notification bar to see if active navigation applications offer an option to quit or exit. You can also adjust the locate mode to try and conserve battery life: Settings > Security & Location > Change the mode to Battery saving
- Applications: some applications and widgets can use a lot of energy when you use them. Others can also behave in a non-battery friendly manner when you are not using them. Apps that use a lot of wireless data (streaming Video or Music, navigation/maps, etc) will take more out of your battery because the wireless radios have to transmit and receive a lot of data. Applications that have frequent updates (social applications, email, IM, etc.) are also active energy consumers. Some live wallpapers and widgets may also be consuming power. In general, observe how long your battery lasts relative to the applications that you are using. There are many system utility applications on the Play Store that can help identify how apps consume resources (power, data, memory) for those so inclined to dig deeper.
- A quick and easy step is to reboot your phone if you have not turned it off in a long time (> 1 week), or if you feel it has become sluggish and its battery life is not what you expected. Press and hold the power key to select the Power Off option. Then turn your phone back on and charge your phone normally. Frequent reboots can help keep poorly behaved applications from using more than its share.
- Wi-Fi: in broad terms, data over Wi-Fi uses less energy than data over cellular (and will also save on usage if you have a cap). However if Wi-Fi is not available you may choose to turn it off as well: Swipe down from the top of the screen, and tap the quick setting Wi-Fi Off.
- Turn Bluetooth off when not in use: Swipe down with 2 fingers from the top of the screen, then tap Bluetooth > toggle Bluetooth off.
- Ensure you do not have duplicate email accounts in different applications. To check for duplicate accounts, touch Settings > Under Accounts touch the account type > Ensure there are no duplicates. To remove an account, touch the account > Touch Menu > Touch Remove account
Battery Saver Mode
Battery Saver helps you keep going on a low battery by automatically restricting mobile data until the next charge. Some apps and services won’t work unless you’re connected to a Wi-Fi network.
1. Swipe the status bar down with two fingers and touch .
2. Touch > Battery Saver and turn it on.
3. To turn on Battery Saver automatically when your power is below a specified level, touch Turn on automatically.
When the phone is in Battery Saver mode, the top (status bar) and bottom (navigation buttons) of the home screen turn orange.
Analyze battery use
You can get detailed information about what level of charge your battery has, how much time remains on current charge, and recommendations on how to adjust your settings to maximize battery life.
To review battery use and adjust settings:
1. Go to Settings > Battery.
2. You'll see a list of items using battery power. Touch an item to see detailed information about its usage and, where applicable, adjust settings to reduce its usage.
3. Touch the battery history graph to see more details about how power-intensive activities are using the battery. For example, the following graph shows that an extended period of heavy use, with the screen on continuously, discharged the battery faster than normal.
If your battery history shows steep declines, check the following:
1 - Cellular network signal - As the network signal gets weaker, the phone uses up to three times more battery power than normal to maintain the network connection. Colors indicate the signal strength:
|Gold||Moderate to poor signal|
|Red||Scanning for network|
|Black||Not using cellular network|
If the signal strength is poor or worse, move to a location with a better network signal or use Wi-Fi for data.
Tip: A weak network signal can also cause static on calls, one way calls, dropped calls, connectivity and data issues, slow performance, and other issues. Even if your geographic area has good network coverage, building walls, underground locations, dead spots in coverage, and other environmental factors can impede the signal. In this case, move near a window or use Wi-Fi.
2 - GPS - Blue indicates that GPS was on. When possible, charge your phone while using GPS.
3 - Wi-Fi - Blue indicates that Wi-Fi was on, but not necessarily connected with a Wi-Fi network. When possible, use Wi-Fi for data.
4 - Awake - Blue indicates that an app was preventing the phone from going into sleep mode when idle, usually to complete some task. However, some user-installed apps can drain the battery by keeping the phone in awake mode longer than necessary.
5 - Screen on - Blue indicates that the screen was on. If this is draining your battery, decrease the screen timeout (inactivity before your phone sleeps) to 1 minute or less, set screen brightness to automatic, limit live wallpapers, and press the Power button to turn off the screen when not needed. Consider charging your phone during heavy use, particularly when using games or apps that use frequent background data.
6 - Charging - Green indicates that the phone was charging.
