Google Pixel 9 Pro vs Samsung Galaxy S25 Ultra

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.

Samsung Galaxy S25 Ultra

Virtually every reviewer calls the S25 Ultra display the best on a smartphone, thanks to the Gorilla Armor 2 anti-reflective coating that practically eliminates glare in sunlight, the 2,600-nit peak brightness, and the sharp 1440p LTPO panel. A few reviewers note PWM dimming only reaches 480 Hz and peak auto-brightness doesn't always sustain.

• The anti-reflective coating makes it one of the easiest phones to use in direct sunlight and held up well to scratches over a week of abuse.
• The Gorilla Armor 2 panel strikes an almost perfect balance between glossy and matte, with 2,600-nit peak brightness that dazzles in any environment.
• The S25 Ultra's anti-reflective screen eclipses every other smartphone right now, especially under harsh sunlight.
• After six months of use it is simply put: the best display I've ever seen on mobile — the bezels, brightness and colors are unbeatable.
• The low-glare, bright LTPO display is a strength, but PWM dimming is only at 480 Hz which can bother sensitive eyes.
• The display still only hits around 850 nits with the manual brightness toggle, so you rarely see the full peak brightness outside of HDR.
• Even without a huge display upgrade, this is still absolutely one of the best displays — super crisp, very bright, high-refresh-rate LTPO.
• Slimmer bezels grow the screen to 6.9 inches without making the body larger, and the Gorilla Armor 2 glass looks great.
• r/Android commenters who upgraded from the S23 Ultra call out the titanium body and the non-reflective screen as the two features they actually notice day-to-day.

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.

Samsung Galaxy S25 Ultra

The 5,000 mAh battery is unchanged but the more efficient chip pushes real-world endurance comfortably beyond a day — Engadget measured 29h 27m video runtime, Mrwhosetheboss got nearly 9 hours of screen-on time. Wired charging tops out at 45W, wireless at 25W. The Qi2 Ready implementation without built-in magnets is a consistent frustration, and Reddit users openly say the OnePlus 13's silicon-carbon battery was the more exciting release this year.

• Most days end with 60 percent left over — good but not amazing for a modern flagship.
• Local video rundown lasted an incredible 29 hours 27 minutes — almost two hours longer than the S24 Ultra.
• Battery life is just under 9 hours of total screen-on time per charge, regularly ending days with 30-40 percent remaining.
• Standby time after half a year of use remains excellent — never a single battery issue during long-term testing.
• Qi2 Ready is frustrating — you need a third-party magnetic case for MagSafe-like functionality, and some cases have weak magnets that pop off.
• Samsung is cutting corners by calling the phone Qi2 Ready without including magnets, and as the biggest phone maker it should do better.

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.

Samsung Galaxy S25 Ultra

One UI 7 on Android 15 is Samsung's biggest skin update in years and earns broad praise for polish. Gemini replaces Bixby as the default assistant on long-press and gains cross-app actions, though the experience is uneven — some reviewers report magical moments, others catch hallucinations. Samsung has committed to seven years of updates, and Galaxy AI is free only through the end of 2025. The r/gadgets thread is openly hostile toward the AI pitch — most top comments view it as bloat, tracking, or a distraction from real hardware progress.

• Gemini can put events on the calendar, but it also hallucinates recipes and insists flights leave the wrong city — AI makes things up a lot.
• Galaxy AI features will be free only through the end of 2025, so don't be surprised if the AI phone comes with an AI subscription fee.
• Having two assistants (Gemini and Bixby) is confusing, and Now Brief still hasn't produced anything insightful in two weeks of use.
• Improved natural-language commands throughout the phone feel slightly magical — asking the phone to add the next Knicks game to a calendar just works.
