your app. [ ![Deliver Live Updates to your Capacitor app with Capawesome Cloud](../../../assets/external/cloud.capawesome.io/assets/banners/cloud-build-and-deploy-capacitor-apps.69628c3f.png) ](https://cloud.capawesome.io/) ## Features[ΒΆ](#features "Permanent link") * 🌑️ **Thermal state**: Read the current thermal state of the device. * πŸ”” **Change events**: Get notified whenever the thermal state changes. * πŸ“¦ **CocoaPods & SPM**: Supports CocoaPods and Swift Package Manager for iOS. * πŸ” **Up-to-date**: Always supports the latest Capacitor version. Missing a feature? Just [open an issue](https://github.com/capawesome-team/capacitor-plugins/issues) and we'll take a look! ## Newsletter[ΒΆ](#newsletter "Permanent link") Stay up to date with the latest news and updates about the Capawesome, Capacitor, and Ionic ecosystem by subscribing to our [Capawesome Newsletter](https://cloud.capawesome.io/newsletter/). ## Compatibility[ΒΆ](#compatibility "Permanent link") | Plugin Version | Capacitor Version | Status | | -------------- | ----------------- | -------------- | | 0.x.x | \>=8.x.x | Active support | ## Installation[ΒΆ](#installation "Permanent link") You can use our **AI-Assisted Setup** to install the plugin. Add the [Capawesome Skills](https://github.com/capawesome-team/skills) to your AI tool using the following command: `[](#%5F%5Fcodelineno-0-1)npx skills add capawesome-team/skills --skill capacitor-plugins ` Then use the following prompt: `` [](#%5F%5Fcodelineno-1-1) Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capawesome/capacitor-thermal-state` plugin in my project. `` If you prefer **Manual Setup**, install the plugin by running the following commands and follow the platform-specific instructions below: `[](#%5F%5Fcodelineno-2-1)npm install @capawesome/capacitor-thermal-state [](#%5F%5Fcodelineno-2-2)npx cap sync ` This plugin is available on **Android** and **iOS**. On the web, all methods reject as unimplemented. ### Android[ΒΆ](#android "Permanent link") Reading the thermal state requires **Android 10** (API level 29) or newer. On older versions, `getThermalState(...)` rejects as unavailable and the `thermalStateChange` event is never emitted. The Android thermal status values are mapped to the four common thermal states as follows: | Android Thermal Status | Thermal State | | ------------------------------------------------------------------------------------------------------------ | ------------- | | THERMAL\_STATUS\_NONE | nominal | | THERMAL\_STATUS\_LIGHT | fair | | THERMAL\_STATUS\_MODERATE | serious | | THERMAL\_STATUS\_SEVERE / THERMAL\_STATUS\_CRITICAL / THERMAL\_STATUS\_EMERGENCY / THERMAL\_STATUS\_SHUTDOWN | critical | ## Configuration[ΒΆ](#configuration "Permanent link") No configuration required for this plugin. ## Usage[ΒΆ](#usage "Permanent link") `[](#%5F%5Fcodelineno-3-1)import { ThermalState } from '@capawesome/capacitor-thermal-state'; [](#%5F%5Fcodelineno-3-2) [](#%5F%5Fcodelineno-3-3)const getThermalState = async () => { [](#%5F%5Fcodelineno-3-4) const { state } = await ThermalState.getThermalState(); [](#%5F%5Fcodelineno-3-5) return state; [](#%5F%5Fcodelineno-3-6)}; [](#%5F%5Fcodelineno-3-7) [](#%5F%5Fcodelineno-3-8)const addThermalStateChangeListener = async () => { [](#%5F%5Fcodelineno-3-9) await ThermalState.addListener('thermalStateChange', event => { [](#%5F%5Fcodelineno-3-10) console.log(event.state); [](#%5F%5Fcodelineno-3-11) }); [](#%5F%5Fcodelineno-3-12)}; [](#%5F%5Fcodelineno-3-13) [](#%5F%5Fcodelineno-3-14)const removeAllListeners = async () => { [](#%5F%5Fcodelineno-3-15) await ThermalState.removeAllListeners(); [](#%5F%5Fcodelineno-3-16)}; ` ## API[ΒΆ](#api "Permanent link") * [getThermalState()](#getthermalstate) * [addListener('thermalStateChange', ...)](#addlistenerthermalstatechange-) * [removeAllListeners()](#removealllisteners) * [Interfaces](#interfaces) * [Type Aliases](#type-aliases) ### getThermalState()[ΒΆ](#getthermalstate "Permanent link") `[](#%5F%5Fcodelineno-4-1)getThermalState() => Promise ` Get the current thermal state of the device. Only available on Android (API level 29+) and iOS. **Returns:** `Promise<[GetThermalStateResult](#getthermalstateresult)>` **Since:** 0.1.0 --- ### addListener('thermalStateChange', ...)[ΒΆ](#addlistenerthermalstatechange "Permanent link") `[](#%5F%5Fcodelineno-5-1)addListener(eventName: 'thermalStateChange', listenerFunc: (event: ThermalStateChangeEvent) => void) => Promise ` Listen for changes to the thermal state of the device.

Reduce the workload as much as possible. * `fair`: The thermal state is slightly elevated. Consider reducing non-essential work. * `nominal`: The thermal state is within normal limits. No action is needed. * `serious`: The thermal state is high. Reduce the workload to help the device cool down. `'critical' | 'fair' | 'nominal' | 'serious'` ## Handling the Thermal State[ΒΆ](#handling-the-thermal-state "Permanent link") Use the thermal state to progressively reduce your app's workload before the operating system throttles it. The following table lists suggested reactions for each state: | State | Suggested App Reaction | | -------- | -------------------------------------------------------------------------- | | nominal | No action needed. Run at full quality. | | fair | Reduce non-essential work, e.g. lower the prefetching rate. | | serious | Reduce the frame rate, pause prefetching, and defer background or ML work. | | critical | Reduce the workload as much as possible to help the device cool down. | ## Changelog[ΒΆ](#changelog "Permanent link") See [CHANGELOG.md](https://github.com/capawesome-team/capacitor-plugins/blob/main/packages/thermal-state/CHANGELOG.md). ## License[ΒΆ](#license "Permanent link") See [LICENSE](https://github.com/capawesome-team/capacitor-plugins/blob/main/packages/thermal-state/LICENSE).
