In some cases it's also useful to determine the current battery level. Initiate a background update-so you should register a BroadcastReceiver in your manifest to listen for both events by defining theĪCTION_POWER_CONNECTED and ACTION_POWER_DISCONNECTED within an intent filter. Running-particularly as these events should impact how often you start your app in order to It's important to receive these events even while your app isn't The BatteryManager broadcasts an action whenever the device is connected orĭisconnected from power. Monitor the charging state for changes and alter your refresh rate accordingly. The charging status can change as easily as a device can be plugged in, so it's important to Typically you should maximize the rate of your background updates in the case where the device isĬonnected to an AC charger, reduce the rate if the charge is over USB, and lower itįurther if the battery is discharging. Int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1) īoolean usbCharge = chargePlug = BatteryManager.BATTERY_PLUGGED_USB īoolean acCharge = chargePlug = BatteryManager.BATTERY_PLUGGED_AC Status = BatteryManager.BATTERY_STATUS_FULL Int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1) īoolean isCharging = status = BatteryManager.BATTERY_STATUS_CHARGING ||

It keeps track of the battery capacity, when it is full or empty.

Val acCharge: Boolean = chargePlug = BatteryManager.BATTERY_PLUGGED_AC If you are an Android user, then you must be aware of the OS feature called Battery Stats. Val usbCharge: Boolean = chargePlug = BatteryManager.BATTERY_PLUGGED_USB
Val chargePlug: Int = batteryStatus?.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1) ?: -1 || status = BatteryManager.BATTERY_STATUS_FULL Val isCharging: Boolean = status = BatteryManager.BATTERY_STATUS_CHARGING Val status: Int = batteryStatus?.getIntExtra(BatteryManager.EXTRA_STATUS, -1) ?: -1 We'll be handling updates in a later section so it's not necessary. You could pass in an actual BroadcastReceiver object here, but Null as the receiver as shown in the next snippet, the current battery status intent is The BatteryManagerīroadcasts all battery and charging details in a sticky Intent that includesīecause it's a sticky intent, you don't need to register a BroadcastReceiver-by simply calling registerReceiver passing in Start by determining the current charge status. Similarly, you can check the battery charge level, potentially reducing the frequency of-orĮven stopping-your updates when the battery charge is nearly exhausted.

Conversely, if the device is discharging, reducing your update rate helps Is negligible, so in most cases you can maximize your refresh rate whenever the device is connected The impact of performing updates while the device is charging over AC The battery-life impact of performing application updates depends on the battery level andĬharging state of the device. Updates on battery life, checking the current battery level and charging state is a good place to When you're altering the frequency of your background updates to reduce the effect of those
