Roundup: Battery saving tips

by Adam Marks Thu, 09 Jun 2011 1:50 pm EDT

webOS phones have never been known for having long battery lives, even though there have been improvements since the original Pre was released with webOS 1.0. However, a number of our tips focus on ways for you to conserve your battery life, from controlling the screen brightness or knowing how to toggle the various radios in your device on/off. Keep reading after the break for a few easy tips that you can follow to get as much battery power as possible.

  • Adjust screen brightness
    • One of the biggest battery hogs of your device is the large screen that you interact with to do just about everything, and the brighter the screen, the more power it takes up. You should consider keeping the brightness levels down, especially when not on a charger
  • Toggle cellular data on/off
    • The other big drain on your battery comes from your cellular radio that sits inside your phone, especially when you in an area without good service (this is significant worse on CDMA phones, such as those on Sprint and Verizon). Turning off the cellular radio can save you a lot of battery, but be aware that you will be unable to receive any MMS picture messages while your data is turned off, even if you are connected to a Wi-Fi network.
  • Know your gestures: Swipe Down / Connections Menu
    • Swiping down from the top-right of the screen from just about anywhere within webOS will bring down the "Connections Menu" (sometimes called the "Device Menu"). This will allow you to turn on or off your Wi-Fi or Bluetooth radios, as these will also drain your battery if they are turned on and not in use. There are also homebrew patches that will allow you to add a phone/data toggle as well as a GPS toggle to turn those off.
  • Airplane Mode
    • If you want to turn all your radios (voice, data, Wi-Fi, Bluetooth, GPS) off instead of toggling them individually (as explained above), you can access Airplane mode to quickly shut them all down at one. In this standby mode, you will have access to all the data currently on your device and will save a significant amount of battery. Note that you can still re-enable them one at a time if you need access to any of them.
  • Adjust Wi-Fi Sleep Settings
    • If you have access to a Wi-Fi network, not only may you get significantly faster speeds than using your cellular network, but you will actually use less battery to access that data. To get the most of our your battery, you want to make sure that your phone remains connected to the Wi-Fi network, even after you turn off the screen. So, if not already set, make sure you adjust your "Wi-Fi sleep settings" to "Keep Wi-Fi On" when the screen is off.
  • Battery Icon as Percent
    • In the top-right of the screen, there is an icon that indicates the amount of battery remaining, but it's not always clear exactly how much battery is left. Swiping-down to access the Connections Menu will show you the actual percentage remaining, but wouldn't it be better to have that percentage available at all times? If you are comfortable with homebrewing, there are patches available in Preware that will convert the battery icon to a percent. If you are on webOS 1.x or 2.x, you can use just the "Battery Icon as Percent" (or similar) patch, and those users on webOS 2.x can also "Advanced Sysmtes Menus – Framework" patch in conjunction with the Tweaks app to set how the battery icon/percentage is shown.
