While these will not guarantee accurate sleep tracking, we recommend the following measures.
・ Plug in your smart device to keep its battery from running out.
・ Keep the Pokémon Sleep application open (not just running in the background).
・ Place your device by your pillow or somewhere else where it can detect your body movements.
・ Place your device in a place where it won’t detect anyone else’s movements.
Note: If your device is placed on something hard, like a side table or floor, it won’t be able to track your sleep properly.
