Should I keep an unlocked phone awake?¶

Keeping an unlocked phone awake may preserve access, but the method used can also alter the evidence.

Evidential caution: that tapping the screen occasionally is harmless. Each interaction may create activity records, move content, trigger applications or expose new information.

What this means¶

An unlocked phone may lock when the screen times out, the battery drops, the cover closes or security settings re-engage.

Before doing anything, record the screen, active application, time, battery, connectivity and visible account information.

Consider whether preserving access is important enough to justify controlled interaction. The answer depends on the likely evidence, legal authority and availability of specialist support.

Avoid opening menus or navigating through the phone simply to keep it active.

Battery management also matters. A low battery may cause shutdown, while connecting a charger may create a data connection.

A phone kept awake may continue receiving messages, synchronising data or exposing activity to another user.

Where a specialist is available, seek advice quickly on maintaining the live state and managing connectivity.

What to check or do next¶

• Do not change timeout settings or disable security without specialist advice. Those actions can create significant changes.
• If minimal interaction is necessary, use the least intrusive action available and record exactly what was done, how often and what changed.
• Do not claim the phone remained untouched if it was actively kept awake. Record who maintained control of the phone while it was being kept awake.
