Direct answer
For the Nest Cam (wired, 2nd gen), outlet/transformer, contacts, battery temperature/condition and sleep behavior should be isolated. First, use the specified power source and inspect status.
What this covers
- Nest Cam (wired, 2nd gen) (GA01998)
- Google Nest/Home device; Matter/Thread role, wired/battery power, subscription and Google Home migration vary.
- The specific fault this record addresses: has power or battery problems
What it does not cover
- ×The same symptom on a different Google Nest product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.

A switched outlet or a shared circuit
What separates it The device loses power on a schedule that matches household habits, or whenever another appliance runs. Outlets controlled by a wall switch are the classic case and produce a fault that looks entirely like a device failure.
How to confirm Test the outlet with something whose behaviour you can see, and check the breaker for anything sharing the circuit.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the outlet is switched, and what else shares its circuit.
Test whether the outlet is switched or shared
ReversibleAn outlet on a wall switch produces a fault indistinguishable from a device failure. Test it with something whose state you can see, and check what else is on the breaker.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- GA01998. Google Nest/Home device; Matter/Thread role, wired/battery power, subscription and Google Home migration vary.
- Power — plug-in WIRED (no battery on this model)
- The wired 2nd-gen Nest Cam plugs into mains power (USB-C adapter) — this version has no battery, so charging/runtime does not apply; a dead camera is a power/adapter/outlet issue. (Ring/Nest also make battery cams, but this is the wired one.)
- On-device AI
- Detects people, animals, vehicles and packages on-device; some features and event history need Nest Aware. Managed in the Google Home app.
- Recording needs Nest Aware
- Live view and alerts free; recorded history needs Nest Aware. It keeps a few hours of events locally during an internet outage and uploads later. 2.4/5 GHz Wi-Fi.
- Power path
- Mains adapter into a standard outlet. Switched outlets and outlets on a circuit that trips are the two failure modes that present as device faults. Use the supplied adapter — third-party adapters that supply the right voltage at the wrong current are a common cause of intermittent restarts.
- Wi-Fi
- Joins on 2.4 GHz. A phone on 5 GHz cannot hand credentials to it reliably during setup, and a router that steers clients between bands under one network name will produce intermittent joins that look like a hardware fault.
- Service tier
- Some capabilities are subscription-gated. A feature that stops working on a date with no other change is worth checking against the plan's renewal before it is treated as a fault.
- Microphone
- Carries a microphone with a hardware mute. A muted microphone is a physical switch state that no app setting overrides, and is the first thing to check for any voice or audio symptom.
- Symptom boundary
- This record covers Google Nest Nest Cam (wired, 2nd gen) when it has power or battery problems. A different symptom on the same hardware, or this symptom on a different Google Nest product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !The battery is swollen, hot, leaking, or the housing has distorted. Stop charging it, isolate it from anything flammable, and do not puncture or compress it.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Google Nest Help publishes this as "Troubleshoot low battery issues for Nest cameras and doorbells". Google's own camera/doorbell battery-troubleshooting article, titled for this exact symptom. Verified reachable and title-matched via the Browser tool 2026-08-28. What that article does not carry is the model boundary — it is written for a product line, and GA01998 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My Nest Cam went offline — did I lose the footage?+
The wired Nest Cam has some on-device memory, so during a Wi-Fi or internet outage it keeps a few hours of event recordings locally and uploads them once it reconnects — so a brief outage usually does not lose events. For saved history beyond that, you need a Nest Aware subscription. If it is offline, check its power (it is plug-in, so confirm the adapter/outlet) and its 2.4/5 GHz Wi-Fi connection in the Google Home app. Reconnecting it restores live view and uploads the buffered clips.
The device keeps losing power at the same time each day.+
Check whether the outlet is controlled by a wall switch. A switched outlet produces a failure indistinguishable from a device fault, and it tracks household habits rather than anything electrical going wrong.
Is it safe to keep using a swollen battery?+
No. Stop charging it, isolate it from anything flammable, and do not puncture or compress it. Swelling, heat, leaking or a distorted housing are all stop conditions regardless of how well the device otherwise works.
Does this answer apply to every Google Nest model?+
No. It is scoped to GA01998. Google Nest/Home device; Matter/Thread role, wired/battery power, subscription and Google Home migration vary.
What should I record before troubleshooting battery or power?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing battery, power. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for swelling, heat, liquid, corrosion, smoke or damaged wiring.
