Honor Magic V6 vs Vivo X300 Ultra

Honor Magic V6

Snapdragon 8 Elite Gen 5 with the best sustained behaviour in the foldable class — it holds frames far longer than rivals before any throttling.

• Powered by the Snapdragon 8 Elite Gen 5, the Magic V6 surpasses the Galaxy Z Fold 7 on performance.
• After 5 minutes of sustained load every competitor throttles 30–40%, but the V6 drained just 41% over 90 minutes of max load — best in class — with an AnTuTu sustained score of ~847,000, 18% ahead of second place.
• Honor of Kings averaged ~119–120fps at max graphics (3.45–3.65W, ~38–42°C); PUBG Mobile held ~119fps for 30 minutes.
• Genshin Impact at ultra/60fps for 30 minutes averaged 59.5fps with minimal fluctuation, the only trade-off being a screen-brightness drop to ~250 nits.
• Frame rates begin to throttle after about 10 minutes maxed out, but dropping graphics one notch locks a steady 59.74fps at just 41.5°C.

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.

Honor Magic V6

The headline: the biggest battery ever in a foldable, delivering slab-phone endurance in a 4mm-thin body, with fast wired/wireless charging and a 120W charger in the box.

• A 6,660mAh silicon-carbon cell (256/512GB) — the largest ever in a foldable — rising to a 7,150mAh Qinghai Lake battery in the 1TB China model, the first foldable past 7,000mAh.
• It lasted 7 hours 54 minutes from full charge to shutdown — over 2 hours longer than most standard phones — and beat the OPPO Find N5 (5h43m) and Vivo X Fold 5 (4h33m).
• After a full 5-hour mixed-usage test, 69% remained — securing first place on the foldable 5-hour battery leaderboard — with a Bilibili loop running to 13h23m before death.
• Over heavy Lunar New Year use — video, gaming, documents, social — only about 30% of the battery was used per day.
• 80W wired charging hit ~27% in 15 minutes and a full charge in ~49–55 minutes, plus 66W wireless and an included 120W GaN charger.
• More than 7 hours of screen-on time on the inner display alone, easily surpassing 10 hours mixed indoor/outdoor — eliminating battery anxiety.

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.
