Separate your phone physically during deep work
Move your phone to another room — not another pocket — during focus sessions.
Key takeaways
- What it is: Move your phone to another room — not another pocket — during focus sessions.
- Why it works: The Ward et al. research found that cognitive capacity is reduced by the mere presence of a smartphone in view, even when it is silent and face-down. The mechanism is that the phone as an object activates the habit network associated with checking — the brain devotes some resources to the impulse suppression that would not be needed if the phone were absent. Physical distance eliminates the stimulus without requiring ongoing suppression.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Putting the phone "on silent but nearby" — this satisfies the form of separation while leaving the conditioned stimulus and its suppression cost fully intact.
Why it works
The Ward et al. research found that cognitive capacity is reduced by the mere presence of a smartphone in view, even when it is silent and face-down. The mechanism is that the phone as an object activates the habit network associated with checking — the brain devotes some resources to the impulse suppression that would not be needed if the phone were absent. Physical distance eliminates the stimulus without requiring ongoing suppression.
How to do it
- 1When beginning a focus session, place your phone in a separate room — not in a pocket or on the desk.
- 2If you need the phone for two-factor auth or as a timer, face it down in a drawer or sleeve.
- 3Use a dedicated timer device, smart speaker, or computer timer for focus blocks so the phone is not needed.
- 4If leaving the phone in another room feels impossible, that is information about the habit strength — start with "face-down, in a drawer" and work toward full separation.
What the evidence says
RCT / meta-analysisWard et al. (2017) directly showed cognitive performance differences based on phone location: in another room > face-down on desk > face-up on desk. The in-another-room condition outperformed both on-desk conditions on working memory tasks.
Honest caveat: Study used working memory tasks; the magnitude of effect on real-world complex work is extrapolated from this controlled finding.

Common mistake
Putting the phone "on silent but nearby" — this satisfies the form of separation while leaving the conditioned stimulus and its suppression cost fully intact.
IX Coach can be run from a laptop or tablet, so your phone can be in another room entirely during sessions while still using the coaching platform.
