You need the latest version of the Suunto App. From there you can upload more faces to the watch. It was mentioned is the release notes of this weeks Suunto Run firmware update.

@Kriss said in Suunto Run restarts during activity: Also wonder how many days of battery life people are getting? I run every day for an hour with the chest strap, HR 24/7 with the sleep/HRV functions activated, no aod, no notifications, always performace mode when training, which means ~10% per day. The latest update seems pretty good in terms of battery life.
