Improve battery performance on your HTC EVO 3D

Battery performance depends on  many factors, including network configuration, signal strength, the  temperature of the environment in which you operate your phone, the  features and/or settings you select and use, items attached to  connecting ports, and your usage patterns for voice, data and other  programs.


There are several differences between other phones and your new HTC EVO™ 3D that can impact your battery life:

  • HTC EVO 3D has more radios to power (3G, 4G, Bluetooth, Wi-Fi, GPS)
  • HTC EVO 3D has a larger screen than most typical feature phones
  • HTC EVO 3Dhas more capabilities than most typical feature phones
    • Management of multiple email accounts and syncing
    • Wi-Fi access point
    • Wi-Fi Router capability
    • 4G data
    • GPS
    • Access to several third-party applications through the Market
    • Applications and Processes running in the background

Because of all these capabilities and features, it is up to you to manage your battery life experience. Here's how!


Multiple Radios

The  multiple radios on this phone use battery life even when you are not  using them. To improve battery life, turn off your Bluetooth, GPS, 4G,  Wi-Fi and Sprint Mobile Hotspot if you are not using them.

  • Go to Settings > Wireless & Networks and disable any radios that are not in use
  • For  easier control, you can add a widget to the Home screen for each radio  function so you have simple one-touch access to enable or disable each  of them:
  1. Locate an empty space on your Home screen
  2. Tap and hold to bring up the Personalize window
  3. Go to Widgets > Settings >4G
  4. Repeat  these steps to add widgets to control Bluetooth, GPS, Sprint Hotspot  and Wi-Fi, then use these widgets to easily disable any functions when  not in use
  • It is important to ensure 4G is disabled  when your phone is not in a 4G-enabled area, as the battery life will be  shortened while the device performs continuous scans for 4G signal.


Manage Wallpaper, Display Brightness and Screen-On Time

  • Live Wallpapers use more battery power when the screen is turned on. Change to a static wallpaper by going to Personalize > Wallpaper and choosing a static wallpaper in HTC wallpapers or Gallery
  • To manage the screen brightness, go to Settings > Display > Brightness and modify the backlight setting as desired; the less bright the screen, the more battery life you save.
  • When done using the phone, turn the screen off to help preserve battery life. Just quickly tap the Power button on the top edge of the device to power off the screen; the phone will remain powered on but the screen will go dark.


See Your Battery UsageBefore you charge your phone, you can view what has been using your battery during this charge cycle.Settings > About Phone > Battery > Battery use


Email Applications SettingsYou can modify your email settings to download email more or less frequently, as it fits your needs.
  1. From your email inbox, press Menu > More > Settings > Send & Receive
  2. Adjust Update Schedule as desired

Note: Higher email download frequency takes up more battery life.


Preloaded Applications

There  are preloaded applications which update based on frequency settings,  such as Weather and Peep. These applications have a settings menu that  typically can be accessed by using the Menu button while you are in the application. In the settings menu there is an item called Update Schedule

  • Menu > Settings > Update Schedule (this may slightly vary from App to App)

In  general, the less frequently you allow these applications to update,  the better your battery life. If you find there are applications you  don't use at all, for the best battery life experience, configure the  application to either not sync at all or to sync at the lowest  frequency. You can also end the application or service by using the Task Manager application (All Applications > Task Manager).


Google Talk

When  you sign up for the Google Market or Gmail with your Gmail account  information, you are also signed in to the Google Talk instant messaging  application. The Talk application tracks the presence of your Google  Talk contacts in order to let you know who is available to instant  message. Each presence change uses power, even if you do not have the  Talk application open.


If you do not use Talk on your device  or do not mind if it is only operating when you actually have the  application open, then you can eliminate this extra battery consumption:

  1. Press Menu then tap All apps > Talk > Menu > Settings
  2. Uncheck the automatically sign in box
  3. Make sure you exit the application by going to Menu and selecting Sign Out
  4. In  order to again receive Instant Messages through the Talk application,  all you'll need to do is open the Talk application again and it will  automatically sign you in.

Note: Make sure you always exit the application by selecting Sign Out to reduce battery consumption. Exiting the application by use of the  back or home keys will not sign you out and battery life will not be  improved.


TeleNav GPS Navigator

When finished with TeleNav GPS Navigator, return to the main screen of TeleNav GPS Navigator then tap Menu > Exit > Yes to close the program. If you don't do this, it will continue running in  the background and use a significant amount of battery life.


4G

The  4G radio should only be turned on when the improved network speed is  required for an application, such as YouTube, Web Browsing or Sprint  Mobile Hotspot. When not in use, it's important to use the built-in 4G widget (pre-loaded on the Home screen) to turn the 4G radio OFF.


If  you have your 4G radio ON, but are no longer in 4G coverage, then your  device will be scanning in an attempt to re-acquire the 4G network. Your  battery can be significantly drained by scanning, so if you know you  will be out of 4G coverage for an extended period of time or if you are  not acquiring a 4G signal as indicated in the task bar, it is important  to turn your 4G radio OFF.


Even when in 4G markets,  particularly when mobile, you may be going in and out of 4G coverage. If  you notice that you do not have a 4G signal at any point in time,  turning off the 4G radio will save you significant battery life. Simply  turn it back on to check for 4G coverage when you are back in 4G  coverage.

Third-Party Applications

Be  especially cautious with all third-party applications that you download  from the Android Market. Often times these applications have not been  designed with battery life in mind. Many of these applications  significantly impact your battery life and quite often they remain  running even when you exit the application. It's important for you to  understand the behavior of all the applications you download and:

  • Know how to close the application so that it does not continue running; you can often do this by pressing the Menu key while in the application.
  • Learn how to use the Task Manager application or other third-party task managers to identify applications  that are still running even when not in use and to end applications  that are still running but no longer needed.
    • All applications > Task Manager
  • If the applications synchronize data, make sure you optimize the synchronization settings for improved battery life.
