S25 Ultra earns its keep day to day
on June 29, 2026
Posted by: HumBleNessReal
[This review was collected as part of a promotion.] I've used the S25 Ultra daily since I received my pre-order and it has held up better than I expected. Battery easily gets me through long days without a top-up, and the display stays readable outdoors in bright sun, which matters since I'm rarely sitting at a desk.
Galaxy AI is the part that surprised me. The live transcription and summary tools are genuinely useful for capturing notes on the go, and the writing assist cleans up quick messages without me having to stop and re-read everything. Circle to Search has replaced half my normal lookups. These aren't gimmicks I turned off after a week, I actually keep using them.
The camera is the other standout. Detail in low light is strong, and the zoom holds up far better than my last phone. Photos of my kids and quick everyday shots come out sharp with no fiddling.
Performance is smooth with no lag switching between apps, and the S Pen is handy for quick notes. The build feels solid and premium in the hand.
Minor gripe: it's a large phone, so one-handed use takes some adjustment. Worth it for everything else.

I'm much more productive this phone with Galaxy Ai
on June 29, 2026
Posted by: CostaDaPlenty
[This review was collected as part of a promotion.] I mostly use my phone for work, I never thought I would be able to get away from my computer as much as I can with my Z25 Ultra with Galaxy Ai.
Often I don't even need to turn on my computer when I get home in the evenings, I can achieve so much on my phone.
A real efficiency booster.
Thank you Samsung!

This product is extremely good
on June 29, 2026
Posted by: Soultorr02
[This review was collected as part of a promotion.] The Samsung Galaxy S25 Ultra is a powerhouse that seamlessly blends elite performance with daily automation. Driven by the custom Snapdragon 8 Elite for Galaxy chip, it handles graphically intensive gaming at a locked 120 FPS and live-streaming over Discord effortlessly without stuttering or overheating, thanks to an upgraded AI-driven thermal cooling system. This raw performance directly elevates your daily routine through Galaxy AI and automated system routines that eliminate friction. Instead of micromanaging your settings, the phone adapts to your habits: opening a streaming app instantly triggers a routine that optimizes the 6.9-inch glare-reducing display and activates immersive Dolby Atmos audio, while launching a game automatically blocks notifications and shifts power allocation for maximum frame rates. Throughout the day, on-device AI features like Cross-App Action let you use natural voice commands to pull data directly out of media files, while the lock screen's live widgets keep your schedule and updates visible at a glance. By using its massive processing power to automate everyday tasks, the S25 Ultra is more than just a spec-sheet giant—it is an incredibly intuitive companion that actively simplifies your day.

I've always wanted an ultra.
on June 29, 2026
Posted by: Jester
[This review was collected as part of a promotion.] Im a trucker?So i'm constantly on the move.Constantly using my phone for staying in touch with my family through video calls, business signing electronic paperwork, doing online training.
And honestly, when I went from a twenty 22 the twenty five ultra, I thought with the new galaxy aI system i was gonna have issues with getting it to do what I want, not. The case does everything I want. And more love being able to game while I'm waiting to get loaded. And the signal reception is phenomenal.
I know which series i'm gonna be getting from now on And it's gotta be an ultra plain and simple. Now that I've got it, you're never gonna get me to go back. The only recommendation I have is they need to bring back the SD card. Slot with having my life lived out of this phone. There's just not enough memory.
other than that, I love it

Great features, low battery life
on June 29, 2026
Posted by: PrettyE
[This review was collected as part of a promotion.] I love my Galaxy 25 Ultra phone, however it still seems to struggle when it comes to battery life. Galaxy AI has been amazing and I use it quite frequently. The phone works fast and the visuals are wonderful. It takes excellent photos, the only thing that would make this phone perfect is if it had more battery life. I am constantly charging my phone.
