Why does my phone always show `0W`? 47 | 48 | Many phones, especially Samsungs, don't follow the BatteryManager spec. Try changing "Power Scalar Workaround" in the settings view. 49 | 50 | 2. Why does my external power meter show different power numbers than *Wattz*? 51 | 52 | Wattz can only measure power coming into or out of the battery management system. Your external meter is measuring this plus any power your phone is using in addition to that. 53 | 54 | 3. Why isn't the indicator showing up in my status bar? 55 | 56 | *Wattz* needs notification permissions on newer Android phones in order to show the indicator. Make sure to open *Wattz* at least once, where it should prompt you to grant it permissions. Otherwise, check the Android app settings to ensure *Wattz* has notification permissions. 57 | 58 | Keep in mind, Android can revoke these permissions at any time without telling you, so you may need to re-enable them periodically. 59 | -------------------------------------------------------------------------------- /app/src/main/java/dubrowgn/wattz/Battery.kt: -------------------------------------------------------------------------------- 1 | package dubrowgn.wattz 2 | 3 | import android.app.Activity 4 | import android.content.Context 5 | import android.content.Intent 6 | import android.content.IntentFilter 7 | import android.os.BatteryManager 8 | 9 | enum class PlugType { 10 | Ac, 11 | Dock, 12 | Unknown, 13 | Usb, 14 | Wireless; 15 | 16 | companion object { 17 | fun fromRaw(plugType: Int?): PlugType? { 18 | return when (plugType) { 19 | null, 0 -> null 20 | BatteryManager.BATTERY_PLUGGED_AC -> Ac 21 | BatteryManager.BATTERY_PLUGGED_DOCK -> Dock 22 | BatteryManager.BATTERY_PLUGGED_USB -> Usb 23 | BatteryManager.BATTERY_PLUGGED_WIRELESS -> Wireless 24 | else -> Unknown 25 | } 26 | } 27 | } 28 | } 29 | 30 | class Battery(private val ctx: Context) { 31 | private val mgr = ctx.getSystemService(Activity.BATTERY_SERVICE) as BatteryManager 32 | 33 | // configuration 34 | var currentScalar = 1.0 35 | var invertCurrent = false 36 | 37 | private fun prop(id: Int): Long? { 38 | val v = mgr.getLongProperty(id) 39 | if (v == Long.MIN_VALUE) 40 | return null 41 | 42 | return v 43 | } 44 | 45 | private fun prop(id: String): Long? { 46 | val intent = ctx.registerReceiver(null, IntentFilter(Intent.ACTION_BATTERY_CHANGED)) 47 | if (intent?.hasExtra(id) != true) 48 | return null 49 | 50 | val v = intent.getIntExtra(id, Int.MIN_VALUE) 51 | if (v == Int.MIN_VALUE) 52 | return null 53 | 54 | return v.toLong() 55 | } 56 | 57 | fun snapshot(): BatterySnapshot { 58 | val levelScale = prop(BatteryManager.EXTRA_SCALE)?.toDouble() 59 | val level = prop(BatteryManager.EXTRA_LEVEL)?.toDouble() 60 | 61 | return BatterySnapshot( 62 | chargeTimeRemainingRaw = mgr.computeChargeTimeRemaining(), 63 | currentRaw = prop(BatteryManager.BATTERY_PROPERTY_CURRENT_NOW), 64 | currentScalar = currentScalar, 65 | energyRaw = prop(BatteryManager.BATTERY_PROPERTY_CHARGE_COUNTER), 66 | level = level.div(levelScale), 67 | invertCurrent = invertCurrent, 68 | isChargingRaw = mgr.isCharging, 69 | plugType = PlugType.fromRaw(prop(BatteryManager.EXTRA_PLUGGED)?.toInt()), 70 | tempRaw = prop(BatteryManager.EXTRA_TEMPERATURE), 71 | voltsRaw = prop(BatteryManager.EXTRA_VOLTAGE), 72 | ) 73 | } 74 | } 75 | -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @rem 2 | @rem Copyright 2015 the original author or authors. 3 | @rem 4 | @rem Licensed under the Apache License, Version 2.0 (the "License"); 5 | @rem you may not use this file except in compliance with the License. 6 | @rem You may obtain a copy of the License at 7 | @rem 8 | @rem https://www.apache.org/licenses/LICENSE-2.0 9 | @rem 10 | @rem Unless required by applicable law or agreed to in writing, software 11 | @rem distributed under the License is distributed on an "AS IS" BASIS, 12 | @rem WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 13 | @rem See the License for the specific language governing permissions and 14 | @rem limitations under the License. 15 | @rem 16 | 17 | @if "%DEBUG%"=="" @echo off 18 | @rem ########################################################################## 19 | @rem 20 | @rem Gradle startup script for Windows 21 | @rem 22 | @rem ########################################################################## 23 | 24 | @rem Set local scope for the variables with windows NT shell 25 | if "%OS%"=="Windows_NT" setlocal 26 | 27 | set DIRNAME=%~dp0 28 | if "%DIRNAME%"=="" set DIRNAME=. 29 | @rem This is normally unused 30 | set APP_BASE_NAME=%~n0 31 | set APP_HOME=%DIRNAME% 32 | 33 | @rem Resolve any "." and ".." in APP_HOME to make it shorter. 34 | for %%i in ("%APP_HOME%") do set APP_HOME=%%~fi 35 | 36 | @rem Add default JVM options here.
