Step 3: On pressing the enter key, the screen color will change to Blue. Step 2: Select the power menu and choose Start Battery Calibration, and press on Enter. Step 1: Switch on your laptop and press F2 on the boot screen. Most laptops in the world come with an in-built battery calibration in their BIOS.

Therefore, it becomes necessary to figure out ways to calibrate your laptop battery. This primarily happens with laptops that are in heavy use daily or used for gaming. But you and he both know that reality is far from it.Įventually, you struggle even to get an hour of battery life when there’s no power. Speaking all about the hours and hours of work you can do without connecting your laptop to a power source. So while your showroom salesperson impressed you with his persuasive speaking skills. But with the passage of time and use, it reduces drastically. Usually, a battery life of 18-20 hours is considered good. Val batteryPct: Float? = batteryStatus?.One of the primary features of a laptop while buying is its battery life. You can find the current battery charge by extracting the current battery level and scale from The rate of your background updates if the battery charge is below a certain level. 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 || Val acCharge: Boolean = chargePlug = BatteryManager.BATTERY_PLUGGED_AC 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
