Samsung Galaxy A55 5G vs Vivo X300 Ultra

Samsung Galaxy A55 5G

A 50MP f/1.8 OIS main, 12MP ultrawide and 5MP macro, plus a 32MP selfie. Dependable with strong low-light for the class, weaker against true flagships at night.

• Triple rear: 50MP f/1.8 OIS main (1/1.56"), 12MP ultrawide and a 5MP macro.
• Dependable camera performance with excellent videos, per the GSMArena review.
• Versus the iPhone 13 it holds its own in almost every scenario, and clearly wins in low light with less noise.
• Night mode isn't on par with the iPhone 15 or Pixel 8 Pro, but it's a clear improvement and competitive at the price.
• Video records up to 4K 30fps on the main, ultrawide and front cameras, with smoother FHD 60fps available.
• It beats the Nothing Phone (2a) on camera and software support, per owners comparing the two.

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.

Samsung Galaxy A55 5G

Exynos 1480 with up to 8/12GB RAM — solidly midrange. Smooth for daily use thanks to 120Hz, but with occasional micro-stutter under load.

• The A55 ups the ante with more memory (8GB), a faster Exynos 1480 and a superior camera setup over its predecessor.
• There's occasional lag or micro-stutter when launching the camera in social apps or switching between apps.
• 120Hz is well optimised and the UI stays smooth, with the camera even opening slightly faster than on the A56.
• It runs cooler than a Galaxy S24 in sustained tests (A55 ~31–34°C vs S24 ~37–38°C) and beat the A35 on AnTuTu.
• An owner found it ran cooler/better than an S23 FE, which heats up faster even just browsing social media.

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.

Samsung Galaxy A55 5G

A 5,000mAh battery with very strong endurance, undercut by slow 25W wired charging and no wireless charging.

• The 5,000mAh battery can stretch toward two days if you're sensible with gaming and camera use.
• It uses only ~2% battery over 8 hours of 5G standby — far better than a Galaxy S24's ~5%.
• Around 8 hours of screen-on-time means it easily lasts a full day; the battery 'just goes on and on.'
• It does not support wireless charging at all; charging is 25W wired over USB-C only.
• The lack of fast charging is the one thing owners really miss in a rush versus 90W rivals.

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.
• In a head-to-head charge race against the Oppo Find X9 Ultra (80W), the Vivo on 100W finished first at 50 minutes 20 seconds to the Oppo's 52:39.
