Scanning is one of the more demanding things a phone does. The LiDAR sensor is active, the camera is running, the neural engine is building geometry, and the screen is on at full brightness. Over a long day that adds up.
Plan for the charger, not around it
The simplest fix is the obvious one: scan with a cable available. A truck charger between houses, or a small battery pack in your pocket during a large whole-house capture. This is not a workaround for a problem — it is what sustained sensor work costs, and planning for it removes the entire issue.
Heat is the real constraint
Sustained capture warms the phone, and a hot phone throttles — which shows up as a capture that feels sluggish rather than an error message. What helps:
- Between rooms, let it idle for thirty seconds rather than immediately starting the next capture
- Take it out of a thick case on a long session, if the case traps heat
- Keep it out of direct sun during exterior scans, including on the dash between houses
- Charging while scanning adds heat — if it is already warm, charge between captures instead of during
Storage, especially in High Fidelity
Photorealistic captures carry real photo data, and a whole house of them is meaningfully larger than a plain parametric scan. Check free space before a big day, and send completed scans to the office rather than letting a month of houses accumulate on the device.
Screen brightness is free margin
Outdoor scanning pushes brightness to maximum, which is a large share of the drain. In a dim interior, turning it down is the cheapest battery you will find all day.
Order the day well
Do the big whole-house capture first, when the phone is cool and full. Save the single-room jobs for the afternoon.
The phone is not fragile. It is just doing more work than it looks like.
