+    # Add device specific permissions to hal_health_default domain, especially
+    # if a device-specific libhealthd is used and/or device-specific storage related
+    # APIs are implemented.
+    ```
+
+1. Implementing health HAL in recovery. The health HAL is used for battery
+status checks during OTA for non-A/B devices. If the health HAL is not
+implemented in recovery, `is_battery_ok()` will always return `true`.
+
+    1. If the device does not have a vendor-specific `libhealthd`, nothing needs to
+    be done. A "backup" implementation is provided in
+    `android.hardware.health@2.0-impl-default`, which is always installed to recovery
+    image by default.
+
+    1. If the device does have a vendor-specific `libhealthd`, implement the following
+    module and include it in `PRODUCT_PACKAGES` (replace `<device>` with appropriate
+    strings):
+
+    ```bp
+    // Android.bp
+    cc_library_shared {
+        name: "android.hardware.health@2.0-impl-<device>",
+        recovery_available: true,
+        relative_install_path: "hw",
+        static_libs: [
+            "android.hardware.health@2.0-impl",
+            "libhealthd.<device>"
+            // Include the following or implement device-specific storage APIs
+            "libhealthstoragedefault",
+        ],
+        srcs: [
+            "HealthImpl.cpp",
+        ],
+        overrides: [
+            "android.hardware.health@2.0-impl-default",
+        ],
+    }
+    ```
+
+    ```c++
+    // HealthImpl.cpp
+    #include <health2/Health.h>
+    #include <healthd/healthd.h>
+    using android::hardware::health::V2_0::IHealth;
+    using android::hardware::health::V2_0::implementation::Health;
+    extern "C" IHealth* HIDL_FETCH_IHealth(const char* name) {
+        const static std::string providedInstance{"default"};
+        if (providedInstance != name) return nullptr;
+        return Health::initInstance(&gHealthdConfig).get();
