ANC On vs Off: How Much Battery Life Do You Really Lose?

This anc on vs off battery life comparison lines up manufacturer claims for eight ANC headphones side by side: read the ANC-on figure first, because the headline number on most boxes is the ANC-off figure. On claims, the JBL and the soundcore pair post the strongest ANC-on figures.

Here is a question headphone marketing rarely answers plainly: the battery figure on the box — is that with noise cancelling on or off? It matters, because ANC is not free. The microphones and processing that erase the world around you draw power the whole time, and every manufacturer rates the two modes differently. For our video comparison we gathered the manufacturer-published claims for eight popular ANC headphones and put the two numbers side by side. One warning before the figures: every number below is a manufacturer claim — a published maximum under each brand’s own test conditions, not a result we recorded. Your volume, codec and environment will change what you actually get.

Key Takeaways

• Read the ANC-on figure first: the headline number on most boxes is the ANC-off figure, and it is the number you will almost never see in daily use.
• Every number here is a manufacturer claim — a published maximum under each brand’s own test conditions, not a result we recorded.
• A bigger on/off gap is not automatically worse; it often just means the ANC-off rating is generous. What matters for your life is the ANC-on figure.
• Bose rates the QuietComfort Ultra (1st Generation) by listening mode — Quiet Mode versus Immersive Audio — rather than ANC on or off, and Apple publishes no comparable ANC-off figure in the material reviewed.
• Volume, codec, and environment change what you actually get; brands rate at moderate volume with specific codecs.

Note: the video above uses AI-generated visualization footage and manufacturer-published figures — it is not hands-on battery testing.

At a Glance

All figures in this table are manufacturer claims, as stated in the article and each brand’s published material. They are rated maximums, not measured results.

When we lined these eight up for our video, one pattern stood out: the headline number on most boxes is the ANC-off figure, and it is the number you will almost never see in daily use, because most people buy these headphones to use the cancelling. In our comparison, the fair way to read any claim is to find the ANC-on figure first.

Top 3 Picks — Longest ANC-On Claims

JBL Tour One M3 Smart Tx — Longest ANC-On Claim (tied). Up to 40 hours with ANC on, up to 70 hours with ANC off, per the manufacturer claim.

soundcore Space One Pro — Longest ANC-On Claim (tied). Up to 40 hours with ANC on, up to 60 hours with ANC off, per the manufacturer claim.

soundcore Q20i — Longest ANC-On Claim (tied). Up to 40 hours with ANC on, up to 60 hours with ANC off, per the manufacturer claim.

The remaining five models (Sony WH-1000XM6, Bose QuietComfort Ultra 1st Generation, Apple AirPods Max 2, Nothing Headphone (1), Sony WH-CH720N) remain in the full comparison below. FLAG: this Top 3 is a battery-claim ranking only — the article names no overall winner, and no single winner is claimed here.

Sony WH-1000XM6

Sony rates the WH-1000XM6 at up to 30 hours with ANC on and 40 hours with ANC off — a manufacturer claim, and the smallest proportional drop among the flagships in this comparison, at about a quarter of the rated hours.

Pros

• Manufacturer claims up to 30 hours with ANC on.
• Rated on/off gap of about a quarter — the smallest flagship drop here.
• Codec-specific claim published: up to 26 hours on LDAC with ANC on.

Cons

• The 40-hour figure needs ANC off.
• Hungrier codecs reduce the rated figure.

Bose QuietComfort Ultra (1st Generation)

A version note first: the Bose in this comparison is the original 1st-generation Bose QuietComfort Ultra, and its figures should not be read across to any other generation. Bose rates this model by listening mode rather than ANC on or off: the manufacturer claim is up to 24 hours in Quiet Mode, dropping to up to 18 hours with Immersive Audio on.

Pros

• Manufacturer claims up to 24 hours in Quiet Mode for this 1st-generation model.
• Mode-based rating makes the cost of Immersive Audio plain.

Cons

• No ANC-off figure — Bose does not rate this model that way.
• Immersive Audio drops the claim to up to 18 hours.
• Figures are for the 1st-generation model only.

Apple AirPods Max 2

Apple’s claim for the AirPods Max 2 is the simplest in this article: up to 20 hours with ANC enabled, as a manufacturer claim. Apple does not publish a comparable ANC-off figure in the material we reviewed, so no percentage gap is quoted for it. Read it as an ANC-on claim only, and compare it against the other models’ ANC-on figures, not their off figures. That simplest-claim picture is the honest starting point for any does noise cancellation drain battery airpods search — check whether the listing states an ANC-on figure before comparing it with another model’s ANC-on figure.

Pros

• Claim stated for the mode people use: up to 20 hours with ANC on, per Apple.
• No off-mode headline to confuse the comparison.

Cons

• No comparable ANC-off figure published in the material reviewed.
• Lowest ANC-on claim in this lineup.

JBL Tour One M3 Smart Tx

The manufacturer claims up to 40 hours with ANC on and 70 hours with ANC off for the Tour One M3 Smart Tx — both manufacturer claims. The 40-hour ANC-on claim itself is joint-highest in this table.

Pros

• Claims up to 40 hours with ANC on — joint-highest here.
• Up to 70 hours claimed with ANC off.

Cons

• Rated gap of roughly 43%, so the headline flatters it.
• Both figures are rated maximums, not commute results.

Nothing Headphone (1)

The Nothing Headphone (1) shows the biggest rated gap of the eight: the manufacturer claims up to 35 hours with ANC on and 80 hours with ANC off, both using AAC under the brand’s stated test conditions — a drop of more than half between modes.

Pros

• Claims up to 80 hours with ANC off — the highest off-mode claim here.
• ANC-on claim of up to 35 hours still sits mid-pack.
• Test basis stated: AAC, under brand conditions.

Cons

• Biggest rated gap here — over half disappears with ANC on.
• The 80-hour headline is the least useful figure for ANC users.

Sony WH-CH720N

Sony’s lighter model follows the same pattern as its flagship, one tier down. The manufacturer claims up to 35 hours with ANC on and 50 hours with ANC off for the WH-CH720N — matching the Nothing’s ANC-on claim, with a rated gap of about 30%.

Pros

• Claims up to 35 hours with ANC on, matching the Nothing.
• Moderate rated gap of about 30%.

Cons

• The 50-hour figure requires ANC off.
• Claims are rated maximums, exactly like the flagships.

soundcore Space One Pro

soundcore claims up to 40 hours with ANC on and 60 hours with ANC off for the Space One Pro — manufacturer claims, with a rated gap of about a third. At up to 40 hours claimed, its ANC-on figure matches the JBL and the Q20i as joint-highest in this comparison.

Pros

• Claims up to 40 hours with ANC on — joint-highest here.
• Rated gap of about a third between modes.

Cons

• The 60-hour figure is an ANC-off claim.
• Rated maximums under soundcore’s own conditions.

soundcore Q20i

The soundcore Q20i repeats its bigger sibling’s pattern at a budget position: the manufacturer claims up to 40 hours with ANC on and 60 hours without ANC, under brand testing conditions. When we lined the eight up for our video, this was the surprise of the table — the cheapest class of headphone here matching the joint-highest ANC-on claim.

Pros

• Claims up to 40 hours with ANC on — joint-highest, at a budget position.
• Same 40/60 pattern as the Space One Pro.

Cons

• The 60-hour figure is the no-ANC mode.
• Brand testing conditions apply.

What to Know Before You Buy

• These are maximums. Brands rate at moderate volume with specific codecs, and real commutes — higher volume, colder weather, LDAC or other hungry codecs — usually return less.
• Compare modes, not headlines. A “70-hour” headphone and a “40-hour” headphone can be the same product quoted in different modes, as the JBL shows.
• A bigger on/off gap is not automatically worse; it often just means the ANC-off rating is generous. What matters for your life is the ANC-on figure, because that is how most people actually use these headphones.
• Check the model version. The Bose figures in this article are for the 1st-generation QuietComfort Ultra only, and Bose rates by listening mode — Quiet Mode versus Immersive Audio — rather than ANC on or off.
• Missing figures stay missing. Apple publishes no comparable ANC-off figure in the material reviewed, so no gap percentage exists for it here.

How Noise Cancelling Works, in Plain Terms

One guide explains noise cancelling as microphones listening to the world around you and a processor building a counter-sound to cancel it, with different microphone layouts described as feedforward, feedback, and hybrid. None of that technical detail is verified by this guide, so treat it as background for understanding why cancelling costs power at all, and check the listing for what kind of cancelling a model offers rather than taking any guide’s technical description as a finding about a specific model.

Passive Isolation Versus Active Cancelling

One guide draws a line between passive isolation, which is the physical seal of the earcup or ear tip blocking sound, and active cancelling, which is electronics doing extra work on top of that seal. Neither comparison is verified by this guide, so when you read about isolation, ask how much of the quiet comes from the fit and how much from the electronics, and check the listing for what it claims about each.

What Noise Cancelling Struggles With

Several guides agree that noise cancelling handles steady background sound better than sudden sounds, sharp sounds, speech, and wind. None of those observations is verified by this guide, so treat them as questions to weigh against your own listening places — a train cabin, a windy street, an office — rather than as findings about any model in this comparison.

Battery-Saving Habits That Cost Nothing

Several guides list habits that stretch a charge without buying anything new: use cancelling only when you need it, turn it off in quieter places, keep the volume down, switch off extra features you are not using such as auto-pause, in-ear detection, bass boost, always-on voice assistants, and spatial audio, and make sure the ear tips seal well so you can listen quieter. None of those tips is verified by this guide, and no saving figure is claimed here, so treat them as habits to try and judge by your own use, not as promised gains.

Long-Term Battery Health as a Buying Question

One guide shifts the question from a single charge to the life of the battery itself: charge caps, battery-care settings, heat in the earcups, idle drain when the device is supposedly off, storage charge and temperature, and whether a battery can be replaced at all. None of those points is verified by this guide, and no health figure is claimed here, so ask what the maker says about battery care and replacement before assuming a battery lasts as long as the product does.

Codec Choices as a Listing Question

One guide notes that different wireless codecs can draw power at different rates, so the same model can show different claimed runtimes under different codec settings. No codec-drain figure is verified by this guide, and this section does not repeat the existing codec FAQ, so check whether a listing states runtime per codec and which codec your own devices actually use before comparing two claimed figures.

Power-Saving Modes and Spare Power as Listing Questions

One guide describes power-saving modes that cut cancelling effort and swappable spare battery packs as ways to get through a long day. None of those features is verified by this guide, and no saving or capacity figure is claimed here, so check the listing for whether such a mode or pack exists for the model you are considering, and treat any such claim as a listing detail to confirm.

Why Manufacturer Figures Are Hard to Compare

One guide warns that makers test under different conditions, so two claimed figures from two brands are not measured on the same footing, and uniform independent testing would be needed for a true side-by-side ranking. That warning supports, and does not contradict, this guide’s own plain statement about how its figures were sourced, so when you compare two brands, ask what conditions each claim was made under and treat any ranking built on mixed claims as a rough guide, not a measurement.

What a Noise-Reduction Percentage Actually Means

One guide explains that a noise-reduction percentage is a lab benchmark, not a measure of how quiet a place will feel to you, and that the strongest setting is not always the best one for every listener. No percentage figure is verified by this guide, and none is claimed here, so read any such percentage as a lab number to weigh alongside fit, comfort, and your own listening, not as a promise of silence.

Who It’s For

If battery anxiety is your thing, the ANC-on claims point to the soundcore pair and the JBL as the endurance picks on paper, while the Sony WH-1000XM6 balances a strong ANC-on claim with flagship cancelling. If you mostly listen at a desk with ANC off, the off-mode figures flatter almost everything here. Either way, buy on the mode you will actually use — and treat every number in this article as what it is: the manufacturer’s claim, not a promise.

FAQ

Is the battery figure on the box with ANC on or off?

Usually off, or unstated. JBL claims up to 70 hours off against 40 on, and Nothing claims 80 off against 35 on — all manufacturer claims. Always look for the ANC-on figure before comparing two models.

Which model loses the most rated battery with ANC on?

On the manufacturers’ own figures, the Nothing Headphone (1): from up to 80 hours claimed with ANC off to up to 35 with it on, a drop of more than half. The smallest flagship drop here is the Sony WH-1000XM6, from 40 claimed off to 30 claimed on.

Are any of these figures measured results?

No. Every figure here is a manufacturer-published maximum under that brand’s own test conditions. Volume, codec, temperature and ANC use will change what you actually get.

Why does the Bose have no ANC-off figure?

Bose rates the 1st-generation QuietComfort Ultra by listening mode instead: up to 24 hours claimed in Quiet Mode, and up to 18 hours claimed with Immersive Audio on. Those are the figures Bose publishes, so those are the figures quoted here.

Does the codec really change battery life?

On the published claims, yes. Sony claims up to 30 hours for the WH-1000XM6 with ANC on, and a separate up to 26 hours using LDAC with ANC on. Same headphone, same mode, different codec, different figure.

How does noise cancelling actually work?

One guide describes it as microphones listening to outside sound and a processor building a counter-sound to cancel it, with feedforward, feedback, and hybrid microphone layouts. None of that technical detail is verified by this guide, so treat it as background for why cancelling costs power, and check the listing for what kind of cancelling a model offers.

Is passive isolation the same as noise cancelling?

No, as one guide explains it: passive isolation is the physical seal blocking sound, while active cancelling is electronics working on top of that seal. Neither comparison is verified by this guide, so ask how much of the quiet comes from fit and how much from electronics, and check the listing for what it claims about each.

Does noise cancelling work on voices and sudden sounds?

Several guides say cancelling handles steady background sound better than sudden sounds, sharp sounds, speech, and wind. None of those observations is verified by this guide, so weigh them against the places you actually listen — a train, a windy street, an office — rather than treating them as findings about any model here.

How can I stretch battery life without buying anything new?

Several guides suggest the same habits: use cancelling only when you need it, turn it off in quieter places, keep the volume down, switch off extra features you are not using, and make sure the ear tips seal well so you can listen quieter. None of those tips is verified by this guide, and no saving figure is claimed here, so try them and judge by your own use.

Does using noise cancelling wear the battery out faster over time?

One guide separates two questions: how much power cancelling uses on a single charge, and how the battery holds up over months of use, covering charge caps, battery-care settings, heat, idle drain, storage, and replacement. None of those points is verified by this guide, and no health figure is claimed here, so ask what the maker says about battery care before assuming anything about long-term wear.

What should I ask about codecs and battery life?

Ask which codecs the listing offers, whether it states runtime per codec, and which codec your own devices actually use — one guide notes that different codecs can draw power at different rates. No codec-drain figure is verified by this guide, and this question does not repeat the existing codec FAQ, so answer it from the listing, not from a roundup’s table.

Do power-saving modes change anything?

One guide describes power-saving modes that cut cancelling effort and swappable spare battery packs as ways to get through a long day. None of those features is verified by this guide, and no saving or capacity figure is claimed here, so check the listing for whether such a mode or pack exists for the model you are considering.

Can I use noise cancelling without music playing?

One guide lists this as a common question and treats cancelling on its own as a normal use, separate from music playback. That answer is not verified by this guide, so check the listing and the manual for how cancelling behaves with no audio playing before assuming it works the way you expect.

What does ear pressure mean, and should I worry about it?

Several guides describe ear pressure as a feeling some listeners notice with cancelling on, and treat it as a comfort question rather than a defect. None of those descriptions is verified by this guide, so if pressure matters to you, treat it as something to check by trying a model yourself, not as a finding this guide makes.

Why can’t I compare two brands’ battery figures directly?

Because, as one guide warns, makers test under different conditions, so two claimed figures are not measured on the same footing, and a true side-by-side ranking would need uniform independent testing. That warning supports this guide’s own plain statement about how its figures were sourced, so ask what conditions each claim was made under and treat any ranking built on mixed claims as a rough guide, not a measurement.

How These Picks Were Chosen

This guide lines up the published figures for the models in its own comparison and labels them as listings’ claims, with its sourcing stated plainly so a reader can tell a claim from a result. A reader judging any guide should ask what the listing says, whether a figure is a claim or a recorded result, what conditions the claim was made under, and what the guide left out — and treat every figure as a claim to check on the live listing.

Final Verdict

The lesson is simple: read the second number. Every model here is two headphones — the one in the headline, rated with ANC off, and the one you will live with, rated with ANC on. On the manufacturers’ own claims, the soundcore pair and the JBL offer the strongest ANC-on figures, the Sony WH-1000XM6 the most balanced flagship pattern, and the Nothing shows why off-mode headlines deserve suspicion. Choose on the ANC-on claim, and expect real life to land somewhere under it.
