Optimizing your phone’s battery life
When you’re on the go, it’s not always easy to charge your phone’s battery as often as you’d
like. Follow these tips to extend the time between charges:
Turn off wireless functions such as Bluetooth, Wi-Fi, and data connection when you’re not
using them. See the Internet and Bluetooth chapters for details.
Use only GSM networks. See "Using the GSM network of T-Mobile" for details.
Do not use GPS satellites to determine your GPS location. See the "Maps and location"
chapter for details.
Lower the screen brightness. See "Adjusting the screen brightness manually" for details.
Switch off screen animations. See "Switching animation effects on or off" for details
Cut down on activities such as Internet browsing. Wireless data consumes a lot of power.
Avoid making very long phone calls or using the camera for extended periods of time.
Consider carrying a spare battery for times when you can’t charge your battery for an
extended period.
Batteries gradually lose storage capacity over time. Consider replacing your battery after
eight months to a year, or if you notice that the battery life is decreasing.
Using the GSM network of T-Mobile
Switch to using the GSM network of T-Mobile if you are not using a data connection to connect
to the Internet. Connecting to your T-Mobile’s GSM network consumes less battery power.
