Pokémon Sleep, an innovative mobile app developed by The Pokémon Company, aims to blend entertainment with sleep tracking and analysis.
However, some users have encountered a common problem known as “No valid sleep sessions were found,” preventing them from accessing the full potential of the app.
The complete error reads: “Sleep Data Error No valid sleep data was found.”
In this article, we’ll explore the possible causes of this issue and provide effective solutions to fix it.
What Causes “No Valid Sleep Sessions Were Found” On Pokemon Sleep?
Pokémon Sleep, the app that mixes Pokémon with sleep tracking, has a problem called “No valid sleep sessions were found.”
This happens when the app is not actively running, and it stops tracking sleep properly.
Also, low battery levels can interrupt sleep tracking, causing incomplete data and showing an error message.

To get accurate results, it’s essential to place your phone correctly, like keeping it close to your body or under your pillow to detect body movements during sleep.
If you share a bed with someone, you can have individual sleep sessions or position your phone strategically to reduce interference from their movements.
How To Fix “No Valid Sleep Sessions Were Found” On Pokemon Sleep?

If you’re having trouble with sleep tracking on Pokémon Sleep, here are some possible solutions to improve your experience:
1. Keep The App Open
To track your sleep properly with the Pokémon Sleep app, make sure to keep it open and running on your device all night long.
Don’t close the app in the background to ensure uninterrupted sleep tracking.
2. Charge Your Phone
To avoid interruptions from low battery, try to charge your smartphone before going to bed.
If that’s not possible, make sure your phone has enough battery before starting the sleep session.
3. Use Proper Phone Placement
While you sleep, place your phone near your pillow or close to your body.
This way, the app can accurately track your body movements and record sleep data properly.
4. Do Solo Sleep Sessions
If you have trouble tracking sleep while sharing a bed, try sleeping alone for a night or position your phone closer to your body to reduce interference from the other person’s movements.
5. Minimize Excessive Movement
Even though it can be tough to control your movements while asleep, try placing the phone next to a body part that doesn’t move much to get more accurate sleep tracking.
6. Check For Updates
The Pokémon Sleep app is still in its early stages, and it’s possible that some bugs might be causing the “No valid sleep sessions were found” issue.
