2026 was the year smartphone batteries finally crossed 7,000 mAh, telephoto cameras hit 200 MP, and the foldable-vs-bar debate stopped being interesting because both form factors got genuinely good. Here are our picks — every score below is the formula-computed Mars Score, not an editor's opinion.
Best overall: OnePlus 15
Mars Score 78.4 — the highest in our smartphone catalog. The OnePlus 15 is the spec-per-dollar champion of the year: 7,500 mAh of silicon-carbon battery (the largest in any 2026 flagship), 120 W wired and 50 W wireless charging, 16 GB RAM, IP69 rating, at 211 g. In our 30-day battery test it averaged over 9 hours of screen-on time per charge. Where it concedes ground: telephoto reach and update policy (5 years vs Samsung's 7).
Who should buy it: heavy users who want the longest battery life on the market and don't need the absolute best camera.
Best camera and longest support: Galaxy S26 Ultra
Mars Score 75.6. The S26 Ultra pairs a 200 MP main camera with a 6.9" LTPO display at 3,000 nits peak and Samsung's industry-leading 7 years of OS updates. It's heavy (232 g) and expensive, but it's the only 2026 phone you can buy and reasonably expect to use into 2033. Its score lands below the OnePlus mostly on weight and charging speed — if those matter less to you than camera and longevity, this is the pick.
Who should buy it: photo-first Android users who keep phones for many years.
Best iOS: iPhone 17
Mars Score 61.7. If you're in the Apple ecosystem the decision is really iPhone 17 vs iPhone 17 Pro Max (67.5). The base 17 finally got the 120 Hz ProMotion display, and at 194 g it's the lightest phone on this list. The score gap to Android flagships is real and mostly explained by battery capacity (roughly half of the OnePlus) and charging speed — Apple's bet is that ecosystem integration and resale value close the gap, and for iOS buyers it usually does.
Who should buy it: anyone who values low weight, iMessage/FaceTime, and 5+ years of resale value over raw battery numbers.
Best foldable: Galaxy Z Fold 7
Mars Score 69.5. The Fold 7 is the first Samsung foldable where the crease is genuinely hard to find and the closed-state footprint feels like a normal phone. You still pay the foldable tax in weight and battery relative to bars — but as a tablet-replacement working device it has no equal this year.
Best budget: Poco F7 Ultra
Mars Score 70.4 — above several phones costing twice as much. Flagship-class silicon, 120 W charging, and a 2K display; the compromises are camera consistency and software polish. The Redmi Note 14 Pro+ (69.2) is the alternative if availability differs in your market.
How to choose, in four questions
