Nothing Phone 3 specs leak: 5,150mAh battery, 65W charging beat S25 Ultra

A phone built for people who want solid, dependable performance
The Nothing Phone 3 prioritizes battery endurance and practical charging speed over raw processing power.

A week before its official unveiling, Nothing's third flagship phone has had its battery and charging specifications quietly surfaced through a regulatory filing — a reminder that in the modern era, governments often know a product's soul before the public does. The Nothing Phone 3 arrives with a 5,150mAh battery and 65W charging, numbers that place it in thoughtful conversation with the industry's giants without attempting to shout over them. It is a portrait of a company choosing endurance and reliability over spectacle, asking whether steady sufficiency might be more honest than chasing records.

  • A regulatory FCC filing, not a press event, became the source of truth — revealing the Nothing Phone 3's core specs days before the company could frame the story itself.
  • The 5,150mAh battery edges past Samsung's Galaxy S25 Ultra, a quiet competitive move that signals Nothing is serious about positioning itself among premium Android players.
  • Charging lands at 65W, a real improvement over the Phone 2's 45W but a deflation of rumors that had promised 100W — recalibrating expectations just days before launch.
  • The Glyph lighting system, the design signature that defined the brand's identity, is confirmed gone — replaced by a rumored dot matrix panel that has yet to be officially unveiled.
  • Regulatory listings spanning the US, EU, Japan, Canada, Australia, and Taiwan signal that Nothing is executing a genuinely global launch strategy, not a regional experiment.

Nothing's Phone 3 is less than two weeks from its July 1 launch, but a regulatory filing has already told much of the hardware story. The FCC document, covering model number A024, confirms a 5,150mAh battery — 300mAh more than the Phone 2 and just enough to nudge past Samsung's Galaxy S25 Ultra at 5,000mAh. The OnePlus 13 still leads the field at 6,000mAh, but the gap suggests Nothing is treating endurance as a genuine selling point rather than an afterthought.

Charging comes in at 65W, a meaningful step up from the Phone 2's 45W ceiling and level with what Samsung offers on the S25 line. Earlier rumors had floated 100W support, so some enthusiasm will need tempering — but 65W remains competitive for daily use in 2025, even if it doesn't claim any records.

The filing also sketches out Nothing's distribution ambitions, listing Australia, New Zealand, Canada, the EU, Japan, Taiwan, and the United States. Regulatory approval isn't a shipping guarantee, but the breadth of markets named points to a company thinking at global scale.

On the software and design side, Nothing OS 3.3 will run on a metal-framed device powered by the Snapdragon 8s Gen 4 — a chip that trails last year's top performers in raw benchmarks but holds up well under sustained real-world use. More symbolically, the Glyph lighting system that gave the first two Nothing phones their visual identity is confirmed absent, with leaks pointing to a dot matrix panel as its replacement, though nothing official has been confirmed.

Taken together, the Phone 3 reads as a device built for people who want a phone that simply works — all day, every day, and charges back up without drama. Whether that quiet confidence is enough to carve out a larger share of the premium Android market is the question July 1 will begin to answer.

Nothing's next flagship phone arrives in just over a week, and a regulatory filing has handed us the battery and charging specs before the company even takes the stage. The FCC document, spotted by Tech Outlook and verified independently, confirms what the Nothing Phone 3 will pack under the hood—and it tells an interesting story about where this phone sits in the current market.

The filing, which covers model number A024, is straightforward in what it reveals. The battery capacity comes in at 5,150mAh, a meaningful bump from the Phone 2's 4,850mAh. That extra 300mAh might sound modest, but it positions Nothing slightly ahead of Samsung's Galaxy S25 Ultra, which maxes out at 5,000mAh. The OnePlus 13 still wins the capacity race at 6,000mAh, but Nothing is clearly thinking about endurance as a selling point.

The charging speed tells a similar story of incremental but real improvement. The Phone 3 will support 65W charging, a step up from the Phone 2's 45W and matching what Samsung offers with the S25 series. This contradicts an earlier rumor that had suggested 100W support, so expectations may need recalibrating. Still, for a phone launching in 2025, 65W is competitive enough—fast enough to matter in daily use, even if it's not the fastest in class.

The regulatory label embedded in the filing also hints at Nothing's distribution ambitions. The document specifically lists Australia and New Zealand, Canada, the European Union (including France), Japan, Taiwan, and the United States. While regulatory approval doesn't guarantee a phone will actually ship everywhere it's listed, it's a strong signal of where Nothing plans to sell. The company is clearly thinking globally, not just chasing one or two key markets.

Other details from the filing round out the picture. Nothing OS 3.3 will run the show, and the phone will have a metal frame—nothing revolutionary there, but worth noting. The real question mark has been what happens to the Glyph lighting system that made the first two Nothing phones distinctive. The filing doesn't mention it, and Nothing has already confirmed it's gone. Leaks suggest a dot matrix-style lighting panel on the back might replace it, though that hasn't been officially confirmed yet.

The processor powering all this is the Snapdragon 8s Gen 4, a chip that Nothing announced separately. It's not the absolute peak performer—testing with the POCO F7 showed it trails even last year's flagship chips in raw speed—but it holds its own in sustained, real-world workloads. For most users, it'll be more than adequate.

Nothing launches the Phone 3 on July 1, and these regulatory filings give us a clearer picture of what to expect. The battery and charging specs suggest a phone built for people who want solid, dependable performance rather than bleeding-edge specs. It's a phone that seems designed to work all day and charge reasonably fast when you need it to—which, for most people, is exactly what matters.

Why does a regulatory filing matter for a phone that's launching in a week anyway? Wouldn't Nothing just tell us this stuff themselves?

Model

They will, but the filing gets there first. It's public record, so tech outlets can dig it out before the official announcement. It's the difference between hearing about specs on the company's timeline versus finding them yourself.

Inventor

So the 5,150mAh battery—is that actually good? It sounds like a number.

Model

It's solid. It's bigger than what Samsung put in the S25 Ultra, which is their flagship. Not the biggest out there, but it signals Nothing isn't cutting corners on endurance. That matters because a bigger battery usually means the phone lasts longer between charges.

Inventor

And 65W charging instead of 100W—is that a disappointment?

Model

It depends what you expected. If you believed the 100W rumor, sure. But 65W is genuinely useful. It's faster than what they had before, and it matches Samsung's best. The gap between 65W and 100W matters less in practice than the gap between 45W and 65W.

Inventor

The filing mentions all these countries—does that mean the phone's definitely coming to all of them?

Model

Not necessarily. Regulatory approval is a prerequisite, but companies sometimes file in places they don't end up selling. That said, this list is a pretty good roadmap of where Nothing thinks there's a market. They're not just betting on one region.

Inventor

What's the real story here? Is Nothing catching up to Samsung, or are they still behind?

Model

They're doing both. On battery, they're slightly ahead of Samsung's flagship. On charging, they're matching it. But the processor is a generation behind in peak performance. It's not about catching up anymore—it's about finding a different lane. Nothing's building a phone for people who want something that works well without paying for the absolute fastest chip.
