Best AI Phones

Which phone has the best built-in AI, ranked on independent benchmarks and expert testing rather than vendor claims: what on-device AI actually means, what the silicon changes, why the most powerful AI chip is not in the best AI phone, and which handset suits which kind of work.

Updated September 2026

Quick answer: The best AI phone for most people in September 2026 is the Google Pixel 11, because Google designs its Tensor G6 chip around the TPU, its AI accelerator, rather than the CPU. Google states the G6 carries 50% more TPU compute than its predecessor and runs on-device AI tasks up to 3.5 times faster while using up to 3.5 times less energy (Google). The Pixel 11 also gets Gemini features first, and at $899 it has the lowest entry price of the three flagships ranked here. For the widest spread of AI features in one device, the Samsung Galaxy S26 Ultra is the alternative: its Galaxy AI suite covers writing, transcription, live translation and generative photo editing. If you are staying on iOS, the Apple iPhone 18 Pro has the most on-paper AI silicon in any phone. Its rebuilt assistant, Siri AI, arrived with iOS 27 on 14 September 2026, but Apple still labels it a beta. It launched in English only, behind a waitlist, and is not available in the EU (Apple, MacRumors).

This page ranks phones by the AI built into the device. It does not rank the AI apps you install on top. For those, see best AI apps and best AI chatbots. A phone can score badly here and still run every assistant on the market perfectly well.

How we judged these phones

Every ranked phone on this page cleared a bar: more than one independent assessment, from more than one kind of source. The standard, and how we weigh conflicting evidence, is set out in full in how we rank. Here that means third-party benchmarks and controlled tests, expert reviews from people who used the device, and user ratings with real volume behind them. Manufacturer benchmarks, launch-keynote figures and press releases appear on this page only as claims, labelled as such, and never as the reason a phone is ranked.

Only phones you can buy new from the manufacturer are ranked. Apple discontinued the iPhone 17 Pro and iPhone 17 Pro Max on 9 September 2026, when it announced the iPhone 18 Pro, and removed both from its online store (MacRumors). They appear in the unranked section below.

The ranking

No position on this page is sponsored and we earn nothing if you buy any of these phones. Prices are the manufacturer’s US entry price where we could verify it on 30 September 2026, from the manufacturer or its launch announcement. Where we could not, we have written “data not available” rather than repeat a retailer figure that may be a discount.

The rankings in detail

1. Google Pixel 11: best AI phone for most people

The Pixel 11 went on sale on 20 August 2026 at $899, with the Pixel 11 Pro at $1,099 and the Pixel 11 Pro XL at $1,299 (Google). All three run the Tensor G6.

The case for it is a design decision, not a benchmark win. Google builds Tensor around the TPU rather than the CPU. Google states the G6 carries 50% more TPU compute than the G5 and processes on-device AI up to 3.5 times faster using up to 3.5 times less energy, paired with the latest Gemini Nano. Those are Google’s own figures and should be read as its claims.

Independent testing found the G6 behind its rivals on CPU and GPU. Android Authority benchmarked the Tensor G6 on 20 August 2026 and recorded a 37% single-core and 52% multi-core deficit against the Snapdragon 8 Elite Gen 5 on Geekbench 6, a 44% single-core deficit against Apple, and a GPU gap of more than two times against Snapdragon (Android Authority). Android Authority wrote that prioritising TPU performance at the expense of CPU and GPU “starts to look increasingly difficult to justify”. The same testing found the G6 retains about 79% of peak performance at the end of a 20-run stress test, against 50% to 75% for its rivals.

Why it still ranks first. This page ranks AI, not raw speed. On AI specifically the Pixel gets Gemini features first and is the cheapest way into a 2026 flagship. Stuff’s roundup, first published 16 June 2026 and updated 15 September 2026, ranks the Pixel line first for “tight Gemini integration” and for receiving updates before anyone else (Stuff), and Tom’s Guide wrote that the Pixel 10 has the best AI features of any phone (Tom’s Guide).

The Pixel 11 went on sale six weeks before this page was written, and most of the independent review record still attaches to the Pixel 10, ranked fourth below.

2. Samsung Galaxy S26 Ultra: best for feature breadth

Announced 25 February 2026 and released 6 March 2026, running the Snapdragon 8 Elite Gen 5 on a 3nm process with 12GB or 16GB of RAM (GSMArena). Samsung’s US store lists it from $1,299.99 before trade-in (Samsung).

Samsung ships the widest AI feature set of any phone here: Writing Assist, transcription summarisation, real-time voice translation across 13 languages, Circle to Search driven by the S Pen, and generative photo removal and repositioning. Stuff ranks it second in the category, while noting that some additions “aren’t compelling”.

Galaxy AI pricing. Samsung’s footnote, updated in January 2026, states that “Galaxy AI basic features provided by Samsung are free” and that “future releases may include enhanced features or new services that are offered on a paid basis” (Android Authority). The basic features it names include Writing Assist, Interpreter, Note Assist, Photo Assist and Transcript Assist. No date is attached to any paid tier.

3. Apple iPhone 18 Pro: best if you are staying on iOS

The iPhone 18 Pro and 18 Pro Max went on sale on 18 September 2026 at $1,199 and $1,299, with a 2TB storage option for the first time (9to5Mac). Apple’s A20 Pro is built on a 2nm process with a 6-core CPU and a 32-core Neural Engine, and Apple adds a second neural processor, framing the 18 Pro as its ultimate AI device. On specification that is the most AI silicon in any phone on this page.

What independent testing found. Geekbench results reported by MacRumors put the A20 Pro about 21% to 23% ahead of the A19 Pro on single-core, 27% to 28% ahead on multi-core, and 38% to 40% ahead on GPU (MacRumors). Tom’s Guide’s review called the 18 Pro and 18 Pro Max the fastest phones ever (Tom’s Guide). No independent benchmark of the Neural Engine itself has been published.

The assistant. Siri AI, Apple’s rebuilt assistant, runs on the iPhone 15 Pro and later, and Apple limits some of its capabilities to the iPhone 17 Pro, iPhone Air and iPhone 18 Pro models (Apple). It is still labelled a beta; see Siri AI below. Apple’s other shipped features include live translation in Messages and calls, Image Playground with ChatGPT support, Writing Tools, photo Clean Up and Visual Intelligence. Stuff notes that Apple Intelligence “initially faced accuracy problems requiring feature rollbacks”.

More of the processing stays on the handset by design, and what leaves it goes to Private Cloud Compute rather than a general-purpose cloud.

4. Google Pixel 10: best value

The same Gemini feature set as the Pixel 11 on the previous-generation Tensor G5, and the specific device that Stuff ranked first in the category as of its 15 September 2026 update. It will not match the G6’s on-device AI throughput, but it runs the same features, and it has the deepest independent review record of any phone on this page. If price matters more than the newest silicon, this is the value pick.

5. Motorola Razr 70 Ultra: best for choosing your own assistant

The only ranked phone that does not tie you to its maker’s assistant. Moto AI routes through Microsoft Copilot, Perplexity and Google Gemini, with transcription, screenshot storage and notification summaries on top. Stuff ranks it fourth. If you have already picked an assistant and want a phone that defers to it, this is the one that does.

6. Nothing Phone 4a Pro: best for capture and recall

Nothing’s main AI feature is Essential Space, a hub that collects screenshots and voice notes, transcribes them automatically and makes them searchable. It is not a broad suite. Stuff ranks it fifth. It suits anyone whose problem is finding screenshots and notes again. Compare it against a dedicated app from best AI note-taking apps before paying for hardware to solve it.

Which one should you pick?

• Best AI phone overall: Google Pixel 11: AI-first silicon, Gemini features first, $899.
• Best for the widest set of AI features: Samsung Galaxy S26 Ultra: writing, transcription, translation and generative editing in one device.
• Best on a budget: Google Pixel 10: the same Gemini features on last year’s silicon.
• Best if you are staying on iOS: Apple iPhone 18 Pro: the most on-paper AI silicon, with Siri AI still in beta.
• Best for privacy-first processing: Apple’s line: more on-device by design, with Private Cloud Compute for the rest.
• Best if you want to pick your own assistant: Motorola Razr 70 Ultra: Copilot, Perplexity and Gemini all supported.
• Best for sustained performance: Google Pixel 11: it held about 79% of peak at the end of Android Authority’s stress test, where rivals fell to 50–75%.
• Best Android phone for raw speed rather than AI: a Snapdragon 8 Elite Gen 5 device: it beats Tensor G6 by 37% single-core and 52% multi-core.

AI features compared, and where each one runs

Two phones can both list “live translation” and mean different things. This table splits the common features by what they do and, where the manufacturer discloses it, whether the work happens on the handset.

Two limits on this table. First, “hybrid” means the phone decides per request and does not tell you which path it took. Second, no manufacturer publishes a per-feature list of what runs locally, so the right-hand column reflects documented behaviour where it exists and the general pattern where it does not. If a specific feature must work offline for you, test it in flight mode before you rely on it.

For the standalone tools that do these jobs, see best AI for transcription, best AI for translation and best AI photo editors.

The marketing claims worth ignoring

Four numbers and labels dominate AI phone advertising, and none of them is a reason a phone is ranked here.

TOPS figures. Trillions of operations per second is a theoretical peak at a precision the vendor chooses, on a workload it chooses. Two chips quoting the same TOPS can differ by a wide margin on real models. There is no agreed test behind the number.

Feature counts. “Over 20 AI features” counts a notification summariser and a wallpaper generator as equals. Count only the features you would actually use, then ask which of those run locally.

Vendor-run benchmark charts. Every launch keynote chart compares against a selected rival on a selected workload. These appear on this page only as claims.

“AI phone” as a category label. Every flagship sold in 2026 is marketed as an AI phone. The silicon design, the local-versus-cloud split and the assistant’s actual shipping status separate them; the label does not.

What on-device AI does to battery and heat

Running a processor hard is thermally expensive. A phone that posts a high peak score and then throttles will feel fast in a benchmark and slower in the middle of a long job. In Android Authority’s 20-run stress test the Tensor G6 held about 79% of its peak, against 50% to 75% for its rivals. That test measures general performance rather than the AI accelerator, and no comparable sustained test of phone neural processors has been published.

Energy per inference is the other half. Google’s claim for the G6 is that it does on-device AI work using up to 3.5 times less energy than the G5. That is its own figure and has not been independently verified. Features that constantly round-trip to a server also use the radio, which adds to battery drain.

What to check before you buy

1. Name the two or three AI things you will actually do. Transcribe meetings, translate conversations, edit photos, summarise notifications.
2. For each one, find out whether it runs on-device. Test in flight mode in a shop if you can.
3. Check whether it is free permanently or free for now. Samsung has said enhanced Galaxy AI features may be paid in future; Google gates higher usage limits behind Google AI Pro.
4. Check the assistant’s status where you live. Apple’s Siri AI is a beta, launched in English only, with a waitlist, and is not available in the EU at launch.
5. Check regional availability. AI features vary by country, OS version, model and carrier.
6. Ask whether an app would do it. Most AI jobs do not need new hardware; see best AI apps.

What “on-device AI” actually means

Three different things get sold as phone AI:

• On-device inference. A small model runs on the phone’s neural processor. It works offline, nothing leaves the handset, and it is limited by the silicon. Gemini Nano and Apple’s on-device models are this.
• Hybrid. The phone decides per request whether to answer locally or send it up. Most named features work this way, and which path a given request takes is rarely visible to you.
• Cloud with a phone button. The phone is a client. The work happens on a server, it needs a connection, and it is frequently the same model you could reach from any device.

On-device features cost the manufacturer nothing per use. Cloud features carry a marginal cost, and the paid tiers in this category attach to them: Google gates higher usage limits behind Google AI Pro, and Samsung has said enhanced Galaxy AI features may be paid in future. When comparing AI phones, ask how many of the features you need run locally, not how many are listed.

The silicon, compared

CPU figures for the Tensor G6, Snapdragon and Exynos from Android Authority’s 20 August 2026 testing; A20 Pro figures from MacRumors. No independent, comparable NPU benchmark across these chips is publicly available. Every AI-throughput number in this category comes from the chip’s maker.

Siri AI and the iPhone

Apple’s rebuilt, contextual Siri arrived more than two years after it was first promised, and later than the hardware meant to run it.

Apple had targeted spring 2026 and iOS 26.4 for it (Macworld, 11 December 2025). In February 2026 Bloomberg’s Mark Gurman reported the new Siri would not be in iOS 26.4 (GSMArena, TechCrunch), while Apple maintained the upgrade was still coming in 2026 (MacRumors, 12 February 2026). AppleInsider reported in January 2026 that Google Gemini technology would underpin it (AppleInsider, 12 January 2026).

Apple released it as Siri AI with iOS 27 on 14 September 2026. Apple states that it is in beta, in English, with French, Japanese, Korean, Portuguese and Spanish to follow in October; that it was “custom-built in collaboration with Google and its Gemini models”; and that its models run both on device and on servers using Private Cloud Compute (Apple). MacRumors reported that access is through a waitlist in Settings, that waits range from minutes to days, and that Siri AI is not available in the EU at launch (MacRumors, 15 September 2026).

For buyers, AI silicon and AI features are bought separately. Apple has the most on-paper AI silicon and an assistant it still labels a beta. Google’s Tensor G6 trails on independent CPU and GPU tests, and Google ships Gemini features to Pixel first.

How the category changed in 2026

Silicon specialised. In 2026 the chip designs diverged: Google pushed TPU compute at the expense of CPU and GPU, according to Android Authority’s testing; Qualcomm led Android on general performance; and Apple added a second neural processor. “Fastest phone” and “best AI phone” now have different answers.

The assistant became the bottleneck. Apple’s rebuilt Siri, first promised in 2024, reached users in September 2026 as a waitlisted beta, on the phone with the most on-paper AI silicon.

Free became conditional. Samsung’s terms keep basic Galaxy AI free and allow for paid enhanced features, and Google puts higher usage limits behind Google AI Pro.

Other phones worth knowing (not ranked)

These are credible devices that are either no longer sold by their maker or do not yet have enough independent assessment to rank. Each entry states what the maker says, labelled as its claim.

Apple iPhone 17 Pro and iPhone 17 Pro Max. Discontinued by Apple on 9 September 2026 and no longer on Apple’s online store (MacRumors). Stuff ranked the 17 Pro Max third in its AI phone roundup. Apple lists the iPhone 17 Pro models among the devices that get Siri AI’s full capabilities (Apple).

Honor Robot Phone. Launched in China on 12 August 2026 from RMB 9,999, built around what Honor describes as a 4-DoF mechanical gimbal camera system, with an ARRI imaging partnership that includes ARRI LogC3 recording (Honor). Honor describes it as “multimodal embodied interaction” for mobile filmmaking. The AI claims are the company’s own and we found no independent testing of them.

Oppo, Xiaomi and Huawei. These manufacturers sell AI phones mainly in regional markets, with feature sets that differ by market, and English-language independent testing of their AI features is thin. We cannot rank them on the evidence available to us.

What we could not verify

• No cross-vendor NPU benchmark exists publicly. Every on-device AI throughput figure on this page is the chip maker’s own.
• US entry prices for the Pixel 10, Motorola Razr 70 Ultra and Nothing Phone 4a Pro from their makers at the time of writing. We have written “data not available” rather than quote a retailer price that may be a promotion.

Frequently asked questions

What is the best AI phone in 2026?

The Google Pixel 11 is the best AI phone for most people as of September 2026. Google designs its Tensor G6 around the TPU, its AI accelerator, rather than the CPU, and states the chip carries 50% more TPU compute than the previous generation and runs on-device AI tasks up to 3.5 times faster while using up to 3.5 times less energy. The Pixel line gets Gemini features first, and at $899 the Pixel 11 has the lowest entry price of the three flagships ranked here. The Samsung Galaxy S26 Ultra is the alternative if you want the widest spread of AI features in one device.

Does the iPhone have the best AI?

The iPhone has the most on-paper AI hardware, and it ranks third here. Apple’s A20 Pro in the iPhone 18 Pro is a 2nm chip with a 32-core Neural Engine plus a second neural processor. Apple’s rebuilt assistant, Siri AI, arrived with iOS 27 on 14 September 2026, but Apple still labels it a beta; it launched in English only, behind a waitlist, and is not available in the EU. Apple’s other features, including Writing Tools, live translation, Visual Intelligence and photo Clean Up, keep more processing on the device and send the rest to Private Cloud Compute.

Has Apple’s new Siri shipped?

Yes, as a beta. Apple released Siri AI with iOS 27 on 14 September 2026, in English, with French, Japanese, Korean, Portuguese and Spanish due in October. Apple says it was built in collaboration with Google and its Gemini models and runs both on device and through Private Cloud Compute. It works on the iPhone 15 Pro and later, with some capabilities limited to the iPhone 17 Pro, iPhone Air and iPhone 18 Pro models. MacRumors reported that access is through a waitlist in Settings and that it is not available in the EU at launch.

What does on-device AI actually mean on a phone?

It means a model runs on the phone’s own neural processor rather than on a server, so the feature works offline, no data leaves the handset, and the quality is capped by the silicon. Most features marketed as phone AI are hybrid: the phone decides per request whether to answer locally or send it to the cloud, and which path it took is rarely shown to you. A third category is purely cloud-based with a button on the phone. On-device features cost the manufacturer nothing per use; cloud features carry a marginal cost, and the paid tiers in this category attach to them.

Is Galaxy AI free?

Samsung’s basic Galaxy AI features are free, and Samsung has said enhanced features may be paid in future. Its footnote, updated in January 2026, states that “Galaxy AI basic features provided by Samsung are free” and that “future releases may include enhanced features or new services that are offered on a paid basis”. The basic features it names include Writing Assist, Interpreter, Note Assist, Photo Assist and Transcript Assist. No date is attached to any paid tier, and different terms apply to AI features supplied by third parties.

Which phone has the fastest AI chip?

On published specification, Apple’s A20 Pro in the iPhone 18 Pro series: a 2nm part with a 32-core Neural Engine and a second neural processor. On independent CPU testing the Snapdragon 8 Elite Gen 5 leads the Android field, beating Google’s Tensor G6 by 37% single-core and 52% multi-core on Geekbench 6, and Apple’s chips lead on single-core. There is no public, independent NPU benchmark that compares these chips head to head, so every AI-throughput claim in this category comes from the company that made the chip.

Is the Pixel 11 better than the Galaxy S26 Ultra for AI?

The Pixel 11 ranks higher here; the Galaxy S26 Ultra has more AI features. The Pixel 11’s Tensor G6 is built around the AI accelerator and the Pixel line receives Gemini features before other Android phones. The Galaxy S26 Ultra ships a broader suite, including writing assistance, transcription summaries, live voice translation across 13 languages, S Pen Circle to Search and generative photo editing, and has the faster general-purpose chip. Price separates them: $899 against $1,299.99 on Samsung’s US store.

Do I need a new phone to use AI?

Usually not. Most AI assistants run as apps on hardware that is several years old, because the work happens on a server rather than on your handset. A new phone buys you three specific things: features that run locally and therefore work offline and keep data on the device, deeper integration into the operating system such as system-wide writing tools or screen-aware search, and the neural processing headroom for on-device models to run quickly. If what you want is a good chatbot, an app on your current phone will do; see best AI apps.

Which AI phone is best for privacy?

Apple’s line has the strongest architectural case, because more processing stays on the device by design and requests that must leave it go to Private Cloud Compute rather than to a general-purpose cloud service. Google’s Pixel line runs a share of its features through on-device Gemini Nano, which keeps that subset local too. For any phone, the feature list will not tell you which requests leave the device, so check each feature’s documentation rather than a blanket claim about the handset.

Is the Pixel 11 worth it over the Pixel 10?

For on-device AI throughput, Google claims a large step: 50% more TPU compute than the G5, running on-device AI up to 3.5 times faster with up to 3.5 times less energy. For features, the two are close, because the Pixel 10 receives most of the same Gemini capabilities. Android Authority’s benchmarking found the G6’s CPU and GPU gains over the G5 modest, at 18% single-core, 21% multi-core and 7–10% on GPU. If general performance is your reason for upgrading, the Pixel 10 is the better value.

Why isn’t the iPhone 17 Pro Max ranked?

Apple discontinued the iPhone 17 Pro and iPhone 17 Pro Max on 9 September 2026, when it announced the iPhone 18 Pro, and they are no longer on Apple’s online store. This page ranks only phones you can buy new from the manufacturer. The iPhone 18 Pro takes the iOS slot at third, and the 17 Pro models are covered in the unranked section.

What is the cheapest phone with good AI?

Of the current-generation flagships ranked here, the Google Pixel 11 has the lowest entry price at $899, and it is also the top pick. The previous-generation Pixel 10 runs most of the same Gemini features on the older Tensor G5 and is the value pick, though we could not verify its current US price from Google.

What is a TOPS figure and does it matter?

TOPS stands for trillions of operations per second and it is the headline number manufacturers quote for a phone’s neural processor. The figure is a theoretical peak, measured at a numerical precision the vendor chooses, on a workload the vendor chooses, and there is no agreed independent test behind it. Two chips quoting similar TOPS can perform very differently on the models a phone actually runs. Sustained performance under load and energy used per inference change how a phone feels, and neither is captured by a TOPS number.

Which AI phone features actually run on the device?

Typically: voice-recorder transcription, some writing tools, offline translation packs and parts of on-device photo processing. Typically not: image generation and anything answering open-ended questions, which need a large model on a server. Apple says Siri AI’s models run both on device and through Private Cloud Compute. Most named features sit in between as hybrids, where the phone decides per request and does not show you which happened. No manufacturer publishes a per-feature list of what runs where, so the practical test is to switch on flight mode and try the specific feature before depending on it.

Do AI phone features work without internet?

Only the on-device ones. Local features such as on-device transcription, some writing tools and offline translation packs run on the phone’s neural processor and work with no connection. Anything that reasons over a large model, generates images or answers open-ended questions almost certainly goes to a server. Because most named features are hybrid, the reliable way to find out is to enable flight mode and try the specific feature you care about before you rely on it.
