I retrieved battery temperature and voltage information using the intent Intent.ACTION_BATTERY_CHANGED and the values I got are pretty weird. I could not get any clue: temperature=270 and voltage=3782 ! What are these values? Do they have any units like celsius, fahrenheit or milli or micro volt?

Is there a way to see the power consumption of an Android process? I have a rooted HTC Hero, and I have developed some native programs in C language. I want to see the power consumptions of these programs. So, I want a way to measure the power consumption in process level and not in application level as e.g. PowerTutor application does.. Is there an API that can help me develop an application that can do this thing? Can I use /proc/ stats etc.? any ideas on this? neteinstein As said here: Android Battery usage profiling There is a private API, PowerProfile, for retrieving battery consumption

i want to detect battery change at every percentage. I am able to detect battery level once with broadcast receiver. But its not updating value automatically when % change from 66 to 67. Here is my code. private void batteryLevel() { BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { context.unregisterReceiver(this); Log.i("Battery CHANGED******",":: IN RECEIVER"); int rawlevel = intent.getIntExtra("level", -1); int scale = intent.getIntExtra("scale", -1); int level = -1; if (rawlevel >= 0 && scale > 0) { level = (rawlevel

I have some code that extends a service and records onSensorChanged(SensorEvent event) accelerometer sensor readings on Android. I would like to be able to record these sensor readings even when the device is off (I'm careful with battery life and it's made obvious when it's running). While the screen is on the logging works fine on a 2.0.1 Motorola Droid and a 2.1 Nexus One. However, when the phone goes to sleep (by pushing the power button) the screen turns off and the onSensorChanged events stop being delivered (verified by using a Log.e message every N times onSensorChanged gets called).

Some Android devices due to custom Android tweaks are done by manufacturers has some politics about Power Management that breaks some features like push notifications. Huawei - Only Pre-EMUI 5.0 / Android 7 - Go to Settings > "Protected apps", check your app. Sony - Tap on the battery icon. Go to Power Management > STAMINA mode > Apps active in standby > Add your app. Asus - Check your app in the Auto-start Manager. Xiaomi - Security (App) > Permissions > Autostart - Enable your app *New Xiaomi - Settings > Developer Options. Disable "memory optimization". To enabled Developer Options go to

I am using the method setKeepScreenOn(true) and haven't been able to figure out how to call this in relation to the current Activity (which has a content view set). I've been able to get it to work by calling it on one of my buttons which is always present in the view, but this feels wrong - and I'm sure there must be a way to get around this. I tried referencing the current focus like this: getCurrentFocus().setKeepScreenOn(true); but that threw a NullPointerException. Maybe there was no current focus. So, can anyone tell me how I can reference the view class which I am working inside? Thanks
