Google Pixel 9 Pro vs Xiaomi 15

Google Pixel 9 Pro

A 6.3-inch LTPO Super Actua OLED at 120Hz with a 3,000-nit peak — class-leading brightness in a compact phone.

• The Pixel 9 Pro introduced 3,000-nit peak brightness while the iPhone 16 Pro/Pro Max still topped out at 2,000 nits.
• Measured peak brightness of over 2,000 nits keeps the screen legible in all conditions.
• The 6.3-inch Super Actua display is a daily highlight in a phone that's still genuinely pocketable.
• Around an 87.6% screen-to-body ratio with slim, even bezels.

Xiaomi 15

A small but flagship-grade flat AMOLED with class-leading peak brightness. Outdoor visibility is a recurring highlight.

• An independent test clocked the display at 3,175 nits at 20% APL — bright enough to comfortably read in direct sun.
• The phone offers 3,200 nits of peak brightness; a year on, the screen still feels flagship-level for YouTube, Netflix and gaming.
• There is a dedicated sunlight mode you toggle in settings that boosts the panel up to 3,200 nits.
• Whether watching video or gaming, after a year the display still feels flagship level.

Google Pixel 9 Pro

A 50MP wide, 48MP ultrawide and a much-improved 48MP 5x telephoto plus a 42MP selfie — the system reviewers say cements the Pixel as the best camera phone.

• With a refined design, much-improved telephoto camera and great battery life, the Pixel 9 Pro cements its status as the smartphone with the best camera.
• The Pixel 9 Pro has arguably the best camera among the big three flagships, plus Google software like Night Sight and Magic Eraser.
• Camera spec: 50MP wide, 48MP ultrawide, 48MP telephoto and a 42MP front camera.
• In an iPhone 16 Pro Max vs Pixel 9 Pro XL shootout the iPhone won — its images were brighter and preserved highlights better.
• Reviewers were unusually critical of camera and especially video quality for a Pixel, and the camera hardware wasn't noticeably updated.

Xiaomi 15

A Leica-tuned triple 50MP system that reviewers rate among the best you can get in a compact phone, with a large 1/1.3-inch main sensor and a versatile 60mm telephoto. Pro-grade video is strong via the main sensor.

• This is one of the best and most capable camera setups you can currently get in a relatively compact phone.
• Xiaomi swapped the Xiaomi 14 sensor for a new JN5 telephoto with a 60mm focal length, paired with a large 1/1.3-inch main sensor.
• The telephoto offers 2x optical zoom (46mm) but you can still push to ~6x with an impressive level of detail — a strong pick for buyers who don't need extreme reach.
• Portrait shots were compared directly against a Sony a6100 with a 23mm f/1.4 lens (≈35mm equivalent, ~f/2.1 depth of field) and held up well.
• The main camera can shoot 8K30 from the main sensor, and that 8K footage is roughly 50% more detailed than 4K30.
• 4K30 video is consistent with great detail, tasteful colours and good contrast, but 4K60 footage can sometimes look too compressed and mushy.

Google Pixel 9 Pro

A compact ~4,700mAh battery that reviews praised as 'great' but heavy users find can't last a day — the Pixel 9 Pro's most polarising trait.

• Engadget rated the Pixel 9 Pro's battery life as 'great,' a key part of why it recommends the phone.
• Google advertises it as a 24-hour battery on the 6.3-inch Super Actua model.
• For light/moderate use the battery is 'fantastic,' but heavy users call it the worst they've owned — it can't make it through an entire day.
• One owner got about 3h11m screen-on-time from 37% battery in mixed use — modest for heavy days.
• New 45W-class wired charging plus wireless and Battery Share carry over from the Pro line.

Xiaomi 15

A ~5,240mAh cell that beats a Galaxy S25 in head-to-head rundowns and recharges very fast over both wire and wireless — though a HyperOS idle drain divides reviewers.

• The Xiaomi 15 packs a larger ~5,240mAh battery versus a Galaxy S25's ~4,000mAh while only being 27g heavier, and ended a head-to-head rundown at 30% vs the S25's 13%.
• It charges in around 45 minutes with the 90W adapter in the box, and the reviewer had zero issues with battery life in normal mixed use.
• From a fully dead battery a measured charge test reached 66% in 45 minutes, 91% at 1h05m and a full 100% in about 1h15m.
• It also supports 50W wireless charging — faster than typical flagship wired speeds — though there are no Qi magnets built in, so you need a 50W-compatible mat for top speed.
• Xiaomi says battery can run roughly 25% longer than the Xiaomi 14.
• One reviewer reported a real HyperOS idle drain — 15-20 minutes of light morning use (email, WhatsApp, Slack) cost 5-6% and warmed the phone, persisting even on the dimmest setting.

Google Pixel 9 Pro

The Pixel 9 Pro's defining strength — the best Gemini/AI suite on any phone, plus seven years of updates and a year of Gemini Advanced.

• Google put its AI features front and centre this year, alongside a refined design — superb cameras 'with a side of Gemini AI.'
• It has AI infusion all over the software and camera tricks that rival the iPhone 15 Pro Max.
• You get all of Google's software features including Night Sight and Magic Eraser, plus the deepest AI toolset on any phone.
• Some units suffered post-Android-16 connectivity loss until a restart — an OS-update reliability concern.
• Even stripped of Gemini, the just-hardware Pixel 9 is a strong phone — but AI is the headline reason to buy it.

Xiaomi 15

HyperOS is fast and feature-rich (IR blaster, long update commitment) but the bloat, ads and unremovable apps remain the phone's most consistent complaint, and big updates have shifted benchmark behaviour.

• Xiaomi committed to roughly 4 years of major Android OS updates and 5 years of security patches.
• Owners dislike that certain pre-installed apps can't be uninstalled and that HyperOS surfaces ads and unsolicited notifications even on a flagship.
• The HyperOS 3 (Android 16) update is described as one of the riskiest software moves Xiaomi has made; everything still feels like butter day-to-day but Geekbench scores have declined with every major HyperOS update.
• After the Android 16 / HyperOS 3 update many owners report better battery life, and the IR blaster remains a favourite Xiaomi touch.
• A year on the software support has kept the phone feeling fresh and reliable, with a smooth overall experience.
