<p>For your app to be a good citizen, it should seek to limit its impact on the battery life of its
|
|
host device. After this class you will be able to build apps that monitor modify their functionality
|
|
and behavior based on the state of the host device.</p>
|
|
|
|
<p>By taking steps such as disabling background service updates when you lose connectivity, or
|
|
reducing the rate of such updates when the battery level is low, you can ensure that the impact of
|
|
your app on battery life is minimized, without compromising the user experience.</p>
