Samsung Galaxy Z TriFold vs Vivo X300 Ultra

Samsung Galaxy Z TriFold

Samsung split a 5,600 mAh cell into three packs, one per panel, to fit the chassis — that is 27% more capacity than the Z Fold 7 to power 50% more screen, but the lower 1,584×2,160 resolution helps offset the draw. Real-world numbers land between 7 and 9 hours of screen-on time, with a 12h 53m video-loop result in the most exhaustive drain test. Charging is 45 W wired (matching the S25 Ultra) and 15 W wireless — both faster than the Fold 7's, but slower than Huawei's 66 W wired on the Mate XT.

• The triple-cell battery system comes out to 5,600 mAh — only a bit larger than batteries in phones with one small screen, so you may not get much use per charge with the TriFold fully unfurled and running multiple apps.
• First-battery testing returned nearly 7 hours of screen-on time, including roughly 3.5 hours of YouTube on the inner display and almost 2 hours of gaming at max brightness.
• With mixed use, multitasking and video playback, the TriFold averaged about 8 to 9 hours of screen-on time — the Z Fold 7 by comparison lasts around 6 to 7 hours on a charge.
• In a looped-video drain test the TriFold lasted 12 hours and 53 minutes — about two hours less than a Z Fold 7 doing the same task, the extra screen real estate eating into the larger battery.
• 45 W wired charging finally matches the S25 Ultra and is a massive bump over the Z Fold 7 — 20 minutes nets ~46% and 30 minutes ~65%.
• Samsung still trails Huawei on speed — the Mate XT charges at 66 W wired and 50 W wireless versus Samsung's 45 W and 15 W on the same nominal 5,600 mAh capacity.
• If the TriFold had silicon-carbon battery tech like the Honor Magic 8 Pro's 7,100 mAh cell, the phone could be lighter, longer-lasting, or both.

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.

Samsung Galaxy Z TriFold

Samsung priced the TriFold at the equivalent of ~$2,500 in Korea and $2,899 in its short-lived US run — more than buying a Z Fold 7 plus a flagship tablet plus accessories. Reviewers near-universally treat it as a halo product or a tech demo more than a real recommendation. The discontinuation in March 2026 — three months after launch in Korea and roughly 140 days after the US release — confirmed what most of them had said in their hands-ons. Reddit users were openly relieved, the consensus take being 'always was going to happen at this price.' A second-generation TriFold with a thinner hinge, possible S Pen slot and an Elite Gen 5 chip is already rumored.

• The Z TriFold launched in the US at $2,899 — Samsung's most expensive phone ever — and includes one free inner screen-protector replacement plus 50% off a screen repair within the first year.
• It is far cheaper to buy a decent tablet plus a flagship phone — at a time of economic turmoil the TriFold feels frivolous, however impressive the engineering.
• Samsung discontinued the Galaxy Z TriFold in the US after roughly 140 days on sale — barely four months — and announced it is already working on a second-generation TriFold.
• The most-upvoted r/gadgets reaction to the discontinuation: 'this was always going to happen, there isn't actually a meaningful market at this price point yet.'
• On r/gadgets, owners are openly relieved Samsung pulled it — 'I had it for 3 days and went back to my Fold 7… it was just too heavy and too expensive to not have insurance on.'
• Samsung kinda gave the game away when it discontinued the TriFold — it was always more of a concept than a viable product, too expensive, bulky and impractical for this world.
• Even fans concede the form-factor needs another generation — '"more hits than misses" is not the bar you set for a device that costs almost as much as two or three conventional smartphones.'
• On r/Android, an owner who got their unit on launch day is sticking with it: 'I love my Trifold. Still thinner than a Z Fold 5. I do question durability but it's been my daily driver since I was offered the first release day.'
• Rumors point to a TriFold 2 with an entirely new hinge solution designed from the ground up — meaningfully slimmer, with leaks suggesting an S Pen slot built into one of the hinges.

Vivo X300 Ultra

This is a deliberately niche, camera-first flagship: roughly €1,175 in China for 512GB, around £1,399 globally for the phone, and close to €2,600 for the full kit. For the people it's aimed at it draws some of the strongest praise of any 2026 phone; for everyone else, a cheaper X300 Pro or the Oppo Find X9 Ultra may make more sense.

• Last year's X200 Ultra was, in my opinion, one of the best smartphones of 2025 — and this is the best smartphone I've ever used, with the best camera application I've ever used, provided with zero script from Vivo.
• The cameras are nothing short of amazing — this is the best Android camera phone, with image quality better than anything from Samsung.
• The versatility here is just ridiculous — more like a phone in a camera than the other way around, a camera system built from the sum of its many parts.
• If you accept the 35mm main, are willing to tolerate AI processing in some scenes, and don't mind the front-camera stabilisation limits, this Vivo is an excellent choice.
