Maximizing battery life
The battery in your device cannot be removed.
Battery life depends on how you use your device. You can maximize the
life of your battery by following a few easy guidelines:
• Charge your device whenever you can. Charge it overnight.
• Set your screen to turn off automatically after a shorter period of
inactivity (see Set the interval for turning the screen off automatically).
• Keep your battery away from direct sunlight and other sources of heat.
Temperatures over 113 degrees Fahrenheit (45 degrees Celsius) can
permanently reduce the capacity and life span of any lithium-ion
battery.
• As with any mobile phone, if you are in an area with no wireless
coverage, your device continues to search for a signal, which consumes
power. Turn off the phone if you are outside a coverage area (see Turn
wireless services off (airplane mode)). If you live or work in an area of
poor coverage, you might consider purchasing a signal booster (sold
separately) from your wireless service provider. These typically connect
to your broadband Internet connection, if available.

poor coverage, you might consider purchasing a signal booster (sold

Internet connection, if available.
• If you set up an email account in the Email application, set the interval
to automatically download email to every two hours or less frequently
(see Enter advanced account settings).
• Lower the screen brightness (see Turn auto dim on/off).
• Use a Wi-Fi connection to download system updates and applications
from App Catalog (see Update the HP webOS operating system and ).
Downloads occur faster over Wi-Fi than over your wireless service
provider’s data connection, and thus use less battery power.

• Keep in mind that frequent use of instant messaging (IM) can reduce
battery life. Sign out of your IM account when you are not using it (see
Sign out of an IM account).
• Shut down the device completely when you won’t be using it for an
extended period of time (see Shut down your device).
Set up your device
BEFORE YOU BEGIN Make sure the battery is fully charged (see Charge the
battery).
TIP If you think that the battery needs to be replaced, see I need to replace the
battery for instructions.
