Should I keep an unlocked phone awake?¶
Only when preserving the unlocked state has enough evidential value to justify the interaction needed to maintain it.
An unlocked phone can be a temporary opportunity. Keeping it awake can also create new activity.
Access can disappear quickly¶
A phone may lock because of:
- screen timeout;
- cover or lid movement;
- restart;
- battery loss;
- security policy; or
- remote action.
Record the current state first:
Keeping it awake is not neutral¶
A tap or swipe may:
- create touch/input records;
- move the screen;
- dismiss a notification;
- alter application state;
- trigger sync; or
- expose information to another service.
Changing timeout or security settings is a much larger intervention.
If the live state matters, make it a controlled task¶
Where justified:
- nominate one handler;
- use the minimum interaction necessary;
- record each touch and time;
- monitor battery and connection state;
- stop when specialist support takes over or the reason ends.
The practical point is: do not keep a phone awake by habit. Maintain the live state only through a defined, recorded plan.
