Samsung Galaxy S23+

What Reviewers Agree On

Same bespoke Snapdragon 8 Gen 2 for Galaxy (3.36GHz) chip as the S23 Ultra — flagship performance, more efficient than the Exynos S22+
Same 45W wired + 15W wireless charging as the Ultra (only the standard S23 is stuck at 25W)
6.6-inch FHD+ Dynamic AMOLED 2X with 120Hz and 1750-nit peak — beautifully bright in sunlight
Excellent endurance from a 4,700mAh battery and the efficient chip — GSMArena measured ~14h Active Use score and 111h endurance, owners report 12h+ days with 40% left
IP68 + Gorilla Glass Victus 2 + Armor Aluminum frame, redesigned floating-camera look borrowed from the Ultra

Detailed Comparison

Cameras

Samsung Galaxy S23+

Same 50MP main + 12MP ultrawide + 10MP 3x telephoto trio as the standard S23 — no 200MP main, no 10x periscope. Versatile and consistent in daylight; the Ultra's zoom range is the clearest gap.

Cameras: 50MP main (f/1.8, OIS, Dual Pixel AF), 12MP ultrawide (f/2.2, 120°), 10MP 3x telephoto (no 10x periscope like the Ultra), 12MP selfie.
Stuff verdict: 'some of the best mainstream smartphone cameras' — the 3x zoom is a step up from rivals stuck at 2x.
Consistent main camera; can occasionally overexpose with Scene Optimizer on indoors, but largely reliable.
8K video now 30fps (up from 24fps on the S22+), 4K60 on main and selfie cameras with the new 12MP front sensor.

Vivo X300 Ultra

What Reviewers Agree On

The camera system — twin ~1-inch 200MP main and 200MP 85mm periscope plus a large ultrawide — is the best-equipped on any 2026 phone and the entire reason the device exists.
Video is class-leading: 4K 120fps 10-bit Log with Dolby Vision recorded on-device (no SSD), 8K30 across the rear cameras, and 4K 60fps on every lens including the selfie.
Battery life is genuinely strong — roughly 16 hours active-use score, ~7h heavy screen-on time, and 13–14 hour days with charge to spare, on the 6,600mAh cell.
The Zeiss 200mm/400mm telephoto extenders deliver real, usable optical reach (8.7x and 17.4x) with surprisingly good handheld stabilisation.
100W wired charging refills the big battery in roughly 46–50 minutes, with 40W wireless on top.
The 6.82-inch 144Hz LTPO AMOLED is among the best displays available, hitting ~1,900 nits in auto and ~3,300 nits peak.

Deal Breakers

The 35mm (~1.5x) default main focal length is polarising — many reviewers find it too tight/zoomed versus the usual 24mm.
It heats up quickly under sustained camera or gaming load and throttles to roughly 60–65% stability in prolonged stress tests.
The full experience needs the expensive Photography Kit — the global bundle approaches €2,600 and the 200mm lens isn't in every box.
Notebookcheck found it 'hardly better than the X300 Pro in camera performance despite top-notch hardware', and Linus preferred Oppo's less over-sharpened processing.
It launched in China first with a rocky early software state (fixed via updates), and global availability/pricing is limited and steep.

Vivo X300 Ultra

The reason the X300 Ultra exists: a near-1-inch 200MP 35mm main (Sony Lytia 901), a 200MP 85mm periscope, and the best ultrawide sensor on the market, tuned with Zeiss. Reviewers near-universally rate it the best-equipped camera phone of 2026 — with two important caveats: the 35mm default is divisive, and on raw image quality it's only marginally ahead of the cheaper X300 Pro.

At the center is a 200MP main that's nearly a 1-inch sensor (Sony Lytia 901), backed by a 200MP 85mm-equivalent periscope telephoto — the phone is focused on camera quality and, even more so, video.
Featuring three extra-large image sensors, the X300 Ultra's uncompromising camera hardware earned a solid rating — but it's hardly better than the cheaper X300 Pro in actual camera performance despite the top-notch hardware.
I'm not sure I've seen better results from even 1-inch sensors — it's so close to 1-inch and the 35mm focal length makes for more cinematic-looking shots; the 85mm periscope is the sweet spot for portraits.
It still holds the record for the best portrait-mode photos on a smartphone, especially at 85mm and 135mm; the 14mm ultrawide is sharp edge to edge.
Comparing it directly with the Oppo Find X9 Ultra, even though the Vivo looks great at a glance you could edit the Oppo image and get better detail because the Vivo isn't all over-sharpened and crusty.
Schools the Galaxy S26 Ultra in zoom quality without an excessive camera count — shaping up to be one of the best camera phones not just for 2026 but 2027 and 2028.
The 35mm main is divisive — many feel 24mm is better for phone photography and that 35mm is too tight; cropping to 23–28mm shows a noticeable detail drop.

Performance

Samsung Galaxy S23+

The bespoke Snapdragon 8 Gen 2 for Galaxy and 8GB RAM make it indistinguishable from the Ultra for everyday use — much cooler than the Exynos S22+ and still smooth in 2026.

Snapdragon 8 Gen 2 for Galaxy at 3.36GHz with 8GB RAM and 256GB UFS 4.0 base — same chip as the Ultra, runs the global market without Exynos split.
No overheating even with sustained gaming and 4K video editing — a clear improvement on the Exynos S22+'s thermal issues.
Three years in (2026), the chip 'still handles everything' — app opening, multitasking and games like Apex still smooth.
Light Mode performance profile clocks down the X3 core slightly to preserve power without noticeably impacting performance — free extra battery life.

Vivo X300 Ultra

Snapdragon 8 Elite Gen 5 plus Vivo's custom imaging silicon delivers flagship benchmark numbers and strong gaming, but the camera-heavy hardware runs hot — sustained stress tests show roughly 60–65% stability and the camera app warms it up fast.

At the heart is Qualcomm's current flagship Snapdragon 8 Elite Gen 5, supplemented by Vivo's custom VS1 and V3-Plus imaging chips.
It boots in 16 seconds (vs 21s for the S26 Ultra and 19s for the iPhone 17 Pro Max) and posts an AnTuTu score over 3,800,000, stronger than Samsung.
In a prolonged stress test it throttled CPU performance to about 60% of peak — in line with other high-powered flagships — and 3DMark stability landed around 63–66%.
It gets a bit hot after 30–40 minutes of gaming, but with no throttling even past an hour and never uncomfortable to hold; boost mode at max graphics gives around 4 hours of Wuthering Waves on a full charge.
Native 120fps gaming with smooth/very-high graphics in many titles, with temperature barely crossing 35°C and power draw around 4W in battle-royale modes.
Under sustained camera/imaging load the front reached ~46.8°C and the back ~45.2°C, and around 47°C the refresh rate drops slightly though not all the way to 60Hz.

Battery & Charging

Samsung Galaxy S23+

4,700mAh paired with the efficient chip delivers excellent real-world endurance — owners regularly hit 5-8 hours SOT and full days with 40% to spare. Charging is 45W rated (the standard S23 is only 25W) but caps out at ~1h6m to full and needs the correct PPS cable.

4,700mAh battery (up 200mAh from S22+) and 8 Gen 2 for Galaxy give a measured 14h Active Use score and a 111h GSMArena endurance rating — beating the S22+'s 97h.
Real-world: 5-8 hours of SOT typical, with one owner reporting 12 hours of mixed use (YouTube, gaming, Bluetooth, texting) and still 40% left.
After 2.5 years, moderate use still gets 2 days of battery — long-term efficiency holds up well.
45W wired charging: 21% in 10 min, 39% in 20 min, 55% in 30 min, 79% in 45 min, full in ~1h9m.
ChargerLAB confirmed: peak charging is ~40W (drops to 33W after 6 min); a PPS-capable charger is needed — without it the rate caps at 27W.
15W wireless charging supported (Qi); 4.5W reverse wireless to top up Galaxy Buds or a Watch.
Critical gotcha: the in-box cable doesn't trigger Super Fast Charging 2.0 — must buy a 5A PPS cable separately, same issue as the Ultra.

Vivo X300 Ultra

Vivo grew the silicon-carbon cell 10% to 6,600mAh while keeping the body the same size. Real-world endurance is strong — ~16h active-use score, ~7h heavy screen-on, 13–14 hour days with charge to spare — and 100W wired refills it in under an hour, with 40W wireless.

Vivo increased the battery by 10% to 6,600mAh despite the phone being practically the same size on paper.
In our battery test it earned an active-use score of almost 16 hours; 100W charging took it 0–66% in 30 minutes and a full charge in 46 minutes, plus 40W wireless. A charger is in the box except in Europe.
On the China version I'm finishing entire 13–14 hour days with 25–30% left; the global version keeps the 6,600mAh cell so battery life should comfortably last 12–13 hours of heavy use.
Getting nearly 7 hours of screen-on time with very heavy usage from the 6,600mAh silicon-carbon unit, with 100W wired and 40W wireless charging support.
After a 4-hour heavy-usage simulation the phone still had ~45% battery left, which is solid by today's standards, and 100W wired charging takes about 45 minutes to full.
