Improving battery performance

The following tips can help you improve battery performance:

•Charge your phone often. This will not affect the lifetime of the battery.

•Downloading data from the Internet is power consuming. When you're not using the

Internet, you can save power by disabling all data connections over mobile networks.

You can do this from Settings > More… > Mobile networks > Data enabled. This

setting does not prevent your phone from transmitting data over other wireless

networks.
