Nothing Phone (4a) vs Xiaomi 17

Nothing Phone (4a)

A genuine highlight for the price — a big 6.78-inch 120Hz AMOLED that's bright, sharp and HDR-capable, beating similarly priced rivals.

• 6.78-inch AMOLED, 120Hz, 2160Hz PWM, HDR10+, 800 nits typical / 1,600 nits HBM / 4,500 nits peak at 1224x2720 (440ppi).
• The 6.78-inch display is 23% brighter than the 3a, reaching 1,600 nits outdoors with a 4,500-nit HDR peak.
• Brightness goes up to 4,500 nits peak, remaining easily readable outdoors — the display is very strong for this price range and one of the standout features.
• In the real world it hits around 700 nits peak SDR and ~1,550–1,600 nits in HDR, with 460ppi and dynamic 120Hz.

Xiaomi 17

A compact 120Hz LTPO AMOLED that punches well above its size for outdoor brightness, though it uses a different (lower) pixel arrangement than the Pro Max and measured full-screen brightness is well under the headline figure.

• The display is as good as it can get on a compact flagship — high-res, vibrant and as bright as 3,500 nits peak.
• Measured over 1,000 nits in auto mode and over 3,400 nits on a smaller patch — more than enough for good legibility outdoors.
• In controlled testing, manual full-screen white brightness reached only around 1,100 nits — far below the 3,500-nit peak headline figure.
• The standard model's screen doesn't use the new pixel arrangement found in the Pro Max version, though it still holds certain advantages.
• Peak brightness of up to 3,500 nits keeps everything clearly visible even in direct sunlight.

Nothing Phone (4a)

A standout 3.5x periscope telephoto at this price and a solid main camera, undercut by an under-optimised zoom and a basic ultrawide.

• A triple setup — 50MP main, a 50MP periscope telephoto and an 8MP ultrawide — undoubtedly one of the best experiences at this level.
• The telephoto has been tweaked to a much better 3.5x (80mm) zoom factor.
• A telephoto with optical zoom at this price is great, but this is the worst optimisation I've seen on a 3.5x camera — expect disappointment if you buy for the zoom.
• The 3.5x optical-zoom telephoto is one of the biggest highlights, adding much more flexibility than most competitors in this price range, and the cameras are surprisingly capable.
• Each camera here feels better than what you'd get on Samsung at the price, and the main is solid with nice detail.

Xiaomi 17

A capable Leica-tuned main and telephoto pairing lets the compact 17 shoot above its class, but the ultrawide is a clear step backwards and default autofocus on people can be unreliable.

• The main and zoom cameras are nothing short of excellent, though against the Vivo and Pixel 10 Pro it isn't such a clear-cut win.
• The ultrawide is downgraded — poor quality, narrower field of view and still no autofocus.
• The ultrawide lens is just 17mm wide, so the images aren't very wide at all.
• Reviewers loved the Leica tuning on the base Xiaomi 17, even where exposure occasionally clips highlights.
• The 60mm-class telephoto is good, but after a month you find yourself wishing it had more reach.
• Like the Ultra, the Xiaomi 17 can struggle to focus on living subjects unless you dig into settings and enable the motion track-and-focus option, which is off by default.

Nothing Phone (4a)

A capable mid-range chip that handles everyday use and casual gaming well — not a powerhouse, but appropriate for the price.

• Gaming is absolutely possible on this device, with solid everyday performance for the class.
• There's no shortage of substantial hardware upgrades over the 3a, even if the design doesn't stand out as much as the Pro.
• After 24 hours the home screen is extremely customisable and feels massively more functional than iOS, with no responsiveness complaints.
• Gesture-based navigation is fully supported and the overall experience is good thanks to Nothing's optimisations.

Xiaomi 17

The Snapdragon 8 Elite Gen 5 makes the 17 one of the fastest compact phones around, but sustained-load behaviour is the single most contested topic in the coverage.

• Powered by the Snapdragon 8 Elite Gen 5 on a 3nm process, claiming ~20% better CPU performance and ~35% better battery efficiency than the previous generation, with a Geekbench 6 single-core score of 3,367 and multi-core of 9,830.
• If you look at benchmark scores, it is a significant upgrade over the 8 Elite that powered the Xiaomi 15.
• After a month it still feels just as snappy as day one, with high-end titles running at top settings and sustained performance over long sessions holding up well.
• In a prolonged CPU stress test the Xiaomi 17 did worse than expected, dipping to less than 40% of maximum and spiking continuously rather than holding stable.
• In Honkai Star Rail the Xiaomi 17 began throttling after about 3 minutes of gameplay, with the device becoming extremely hot to the touch.
• Got good average FPS with 120fps gaming support and didn't notice much heating in Genshin Impact even after 30–40 minutes.
• The ultrasonic in-display fingerprint scanner is fast with no delays and works even with a tempered-glass screen protector.

Nothing Phone (4a)

A ~5,080mAh cell with 50W wired charging — reviewers call endurance strong, but a notable group of owners report disappointing screen-on time.

• The Nothing Phone (4a) features a ~5,080mAh cell which delivers very strong endurance in everyday use.
• The battery grew slightly — about 80mAh in most markets but a more meaningful 400mAh in India — with a 50W PD unit recommended on the box.
• Several owners report only 4–6.5 hours of screen-on time with moderate use — worse than other phones with similar ~5,000mAh batteries.
• Battery life on this phone is excellent in everyday use.

Xiaomi 17

The headline reason to buy a compact 17: an oversized silicon-anode battery and very fast charging that together solve the usual small-phone endurance problem.

• The massive 6,330mAh battery is truly exceptional for a compact flagship (the China version is 7,000mAh).
• You can get a full day of use, up to ~7 hours of screen-on time and sometimes more depending on usage.
• In a one-month real-world test, 6–7 hours of screen-on time on regular days was normal, dropping to 5–6 hours on heavy days, with up to ~16 hours in benchmark testing.
• Reached close to 9–10 hours of screen-on time on regular use — a genuine full-day battery phone — with 100W wired and 50W wireless charging faster than the iPhone 17 or Galaxy S26.
• 100W charging takes the 6,330mAh battery from 0–100% in as little as 45–46 minutes.
• Measured charging: ~15% in 5 minutes, ~50% in 21 minutes, ~70% in 30 minutes, ~91% in 40 minutes and a full charge in about 61 minutes.
• A standardized battery-life test returned around 22 hours 30 minutes, with a 15%-to-full charge in roughly 43–55 minutes.
• The battery isn't as good as it should be for a 6,300mAh cell — efficiency lags Samsung and Apple.

Nothing Phone (4a)

Near-stock Nothing OS is repeatedly singled out as one of the best, cleanest and most customisable Android experiences at any price.

• The UI is pretty much stock Android, which is the best Android experience — Nothing and Pixel offer the best Android experience.
• While hard to compare to Samsung's far more customisable One UI, Nothing's OS is one of the best ways to experience Android.
• The in-house gallery, voice recorder and weather apps have wonderful design consistency, with everything else left as Google's clean defaults.
• The home screen is extremely customisable with built-in and user-made widgets — fresher, clearer and bolder than iOS.

Xiaomi 17

HyperOS 3 on Android 16 is fast and visually polished but draws repeated criticism for bugs, bloat and missing basics — and the China ROM many global buyers import has real Google-service gaps.

• Runs Android 16 with Xiaomi's HyperOS 3, which is a very aesthetically pleasing UI.
• Feature-rich HyperOS 3 with a promised 5 years of major upgrades, but the software feels cheap with lots of bugs and you have to calculate screen-on time yourself because there's no built-in counter.
• Xiaomi confirmed the entire Xiaomi 17 series gets 6 years of security updates with end-of-life in February 2032.
• On the China ROM there is no Google Play Store out of the box, and you can't get into the Google Discover page — a real friction point for global buyers.
• Proprietary apps like settings, file manager and security ship with built-in ads.

Nothing Phone (4a)

Aggressively priced below the Pixel 10a with a more distinctive design and a real telephoto — the standout budget pick for buyers who want personality.

• It's a good chunk of change cheaper than the $500 Pixel 10a.
• It fits the perfect budget for buyers who can't afford the ~$1,000 needed for an entry-level iPhone 17, with good hardware and excellent battery.
• A very strong mid-range smartphone that stands out with unique design, great display, solid performance and surprisingly capable cameras — definitely worth a closer look.
• Nothing stands out among the crowd with a brand identity strong enough to turn consumers into fans.

Xiaomi 17

At roughly $630 the 17 is aggressively priced for a Snapdragon 8 Elite Gen 5 flagship, but reviewers disagree on whether it's a category-beater or merely a strong-value option in a crowded field.

• At around $630 it's a phone that's scaring the big brands on price-to-performance.
• For being cheaper than the iPhone, the Xiaomi 17 is a really compelling — and noticeably cheaper — option.
• Outside of being a rare compact flagship, the Xiaomi 17 doesn't offer anything significantly better than its competition.
• With a top-tier processor, Leica cameras, great display and a huge fast-charging battery, the Xiaomi 17 is one of the best price-to-performance phones of 2026.
• For a compact phone it didn't feel like a downgrade when switching from an iPhone 17 Pro daily driver.
