-6.1 If the device has a vendor-specific libhealthd.<soc>, add it to static_libs.

-7. Storage related APIs:
-
-7.1 If the device does not implement IHealth.getDiskStats and
-    IHealth.getStorageInfo, add libstoragehealthdefault to static_libs.
-
-7.2 If the device implements one of these two APIs, add and implement the
-    following functions in HealthService.cpp:

-/vendor/bin/hw/android\.hardware\.health@2\.0-service.<device> u:object_r:hal_health_default_exec:s0
-
-# device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
-# Add device specific permissions to hal_health_default domain, especially
-# if Step 6.1 or Step 7.2 is done.

+    1. To keep `healthd` in the build, remove "overrides" section.
+
+1. Create `device/<manufacturer>/<device>/health/android.hardware.health@2.0-service.<device>.rc`
+
+    ```rc
+    service vendor.health-hal-2-0 /vendor/bin/hw/android.hardware.health@2.0-service.<device>
+        class hal
+        user system
+        group system
+        file /dev/kmsg w
+    ```
+
+1. Create `device/<manufacturer>/<device>/health/HealthService.cpp`:
+
+    ```c++
+    #include <health2/service.h>
+    int main() { return health_service_main(); }
+    ```
+
+1. `libhealthd` dependency:
+
+    1. If the device has a vendor-specific `libhealthd.<soc>`, add it to static_libs.
+
+    1. If the device does not have a vendor-specific `libhealthd`, add the following
+        lines to `HealthService.cpp`:
+
+        ```c++
+        #include <healthd/healthd.h>
+        void healthd_board_init(struct healthd_config*) {}
+
+        int healthd_board_battery_update(struct android::BatteryProperties*) {
+            // return 0 to log periodic polled battery status to kernel log
+            return 0;
+        }
+        ```
+
+1. Storage related APIs:
+
+    1. If the device does not implement `IHealth.getDiskStats` and
+        `IHealth.getStorageInfo`, add `libstoragehealthdefault` to `static_libs`.
+
+    1. If the device implements one of these two APIs, add and implement the
+        following functions in `HealthService.cpp`:
+
+        ```c++
+        void get_storage_info(std::vector<struct StorageInfo>& info) {
+            // ...
+        }
+        void get_disk_stats(std::vector<struct DiskStats>& stats) {
+            // ...
+        }
+        ```
+
+1. Update necessary SELinux permissions. For example,
+
+    ```
+    # device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
+    /vendor/bin/hw/android\.hardware\.health@2\.0-service.<device> u:object_r:hal_health_default_exec:s0
+
+    # device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
+    # 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();
+    }
+    ```
+
+    ```mk
+    # device.mk
+    PRODUCT_PACKAGES += android.hardware.health@2.0-impl-<device>

+     *
+     * The Radio is expected to:

+     *   - Create and configure a dedicated interface for the context.
+     *   - The interface must be point to point.
+     *   - The interface is configured with one or more addresses and is capable of sending and
+     *     receiving packets. The prefix length of the addresses must be /32 for IPv4 and /128
+     *     for IPv6.

+     * @param accessNetwork The access network to setup the data call. If the data connection cannot

+     * @param dataProfileInfo Data profile info.
+     * @param modemCognitive Indicates that the requested profile has previously been provided via
+     *     setDataProfile().
+     * @param roamingAllowed Indicates whether or not data roaming is allowed by the user.
+     * @param isRoaming Indicates whether or not the framework has requested this setupDataCall for
+     *     a roaming network. The 'protocol' parameter in the old RIL API must be filled
+     *     accordingly based on the roaming condition. Note this is for backward compatibility with
+     *     the old radio modem. The modem must not use this param for any other reason.
+     * @param reason The request reason. Must be DataRequestReason.NORMAL or
+     *     DataRequestReason.HANDOVER.
+     * @param addresses If the reason is DataRequestReason.HANDOVER, this indicates the list of link
+     *     addresses of the existing data connection. The format is IP address with optional "/"
+     *     prefix length (The format is defined in RFC-4291 section 2.3). For example, "192.0.1.3",
+     *     "192.0.1.11/16", or "2001:db8::1/64". Typically one IPv4 or one IPv6 or one of each. If

+     *     addresses of the existing data connection. The format is defined in RFC-4291 section
+     *     2.2. For example, "192.0.1.3" or "2001:db8::1". This parameter must be ignored unless
