Battery life is the best of any flagship — reviewers and a robotic battery test repeatedly rank it first, easily a full heavy day with hours to spare.
It's the best iPhone Apple had produced — a maxed-out feature set in a barely-wider body than the 15 Pro Max.
The A18 Pro is the standout for sustained gaming: ~20% faster than the 15 Pro and Galaxy S24 Ultra after a 20-minute stress test, holding 120fps stably for 90+ minutes.
The 48MP main is the best iPhone camera for stills Apple had made, with superb 4K/120fps video and best-in-class four-mic audio.
Long-term durability and battery health are excellent — many owners report 96–100% battery health and minimal wear after a year.

Detailed Comparison
Design & Build
iPhone 16 Pro Max
A titanium frame with a microblasted finish and Ceramic Shield, now with a bigger 6.9-inch screen achieved mostly by trimming bezels — it's only ~1mm wider than the 15 Pro Max but very large.
The screen increase came mainly from trimming the bezels — the 16 Pro Max is a mere 1mm wider than the 15 Pro Max.
The titanium frame has a smooth microblasted finish, sandwiched by two slabs of Ceramic Shield Apple says is twice as tough as rivals.
The 16 Pro Max goes from 6.7 to 6.9 inches — an absolutely gigantic phone, in S24 Ultra territory.
It looks and feels basically like a titanium iPhone 15 Pro — durability is fairly similar to the 15 Pro Max and it still picks up scratches.

It's an incremental update over the 15 Pro Max — few useful new features, hard to justify upgrading from it.
Charging is slow (30W wired, no 30W brick sold; 25W MagSafe) — far behind fast-charging Android rivals.
Apple Intelligence shipped late and underwhelmed (no smarter Siri at launch), and base storage is still a stingy 128GB at $1,199.
OnePlus 15T
What Reviewers Agree On
The 7,500 mAh silicon-carbon 'Glacier' battery is unprecedented in a 6.32-inch body and delivers roughly 1.5 days of real-world endurance — easily the longest battery life in the compact-flagship class.
Build quality is genuine flagship-grade: metal frame, IP66/IP68/IP69/IP69K dust + water resistance, ultrasonic in-display fingerprint sensor, and a 91% screen-to-body ratio with ~1.1 mm symmetric bezels.
The 6.32-inch 165 Hz 1.5K AMOLED reaches the advertised 1,800 nits in standard measurement and is marketed up to 3,600 nits peak — making it the only true 165 Hz compact-flagship display on the market.
Snapdragon 8 Elite Gen 5 + 16GB LPDDR5X Ultra Pro RAM hits Geekbench multi-core ~10,976 and 3DMark Wild Life Unlimited ~29,901 — top-tier flagship synthetic performance in a sub-200g chassis.
100W wired SuperVOOC and 50W wireless charging mean even the giant battery refills fast.
The new 3.5x periscope telephoto with OIS is a meaningful step up from the OnePlus 13T's limited 2x zoom and is well-suited to portraits at the classic 85 mm focal length.
Deal Breakers
China-only launch with no confirmed global release — ColorOS instead of OxygenOS, no eSIM support, no WearOS support, and missing European LTE band 20 and band 32 make it a compromise outside China.
Notebookcheck measured pronounced sustained-performance throttling of over 50% in 3DMark stress tests, with surface temperatures climbing past 46 °C; SuperSaf hit 50 °C on the back during Wildlife Extreme and saw scores drop from 6,990 to 3,743 inside a single loop.
No ultrawide camera at all — the 'triple camera' is just main + 16MP front + 3.5x periscope telephoto, which is a downgrade versus the OnePlus 15 for anyone who shoots landscapes, group photos or wide-angle video.
Charging port is still USB 2.0 in 2026, which SuperSaf calls 'a choice and not a good one' on a flagship-tier device at this price.
No built-in MagSafe-style magnets — wireless-charging accessories require a separate magnetic case to align properly.
Long-term durability and battery health are excellent — many owners report 96–100% battery health and minimal wear after a year.

It survived a JerryRigEverything-style durability/drop test (Ceramic Shield improvements).
OnePlus 15T
OnePlus inherits the design language of the OnePlus 15 — metal frame, glass back, micro-arc oxidation finish on the rails — and shrinks it into a 6.32-inch, 194g body that's roughly iPhone 17-sized but with more than twice the battery capacity. IP66/IP68/IP69/IP69K rating, ultrasonic fingerprint sensor and ~1.1mm symmetric bezels are unambiguous flagship moves. Reviewers debate whether 6.32-inch genuinely counts as compact in 2026.
Same premium design as the OnePlus 15 — metal frame, glass back, IP69 water resistance — feels high-quality in the hand at just 194g.
Dimensions and weight are similar to an iPhone 17, but the 15T packs more than twice the battery capacity with a ~91% screen-to-body ratio.
Full-level water resistance and a fast ultrasonic fingerprint sensor make the 15T noticeably more confident outdoors than the OnePlus 13T was.
The metal frame uses a micro-arc oxidation process with a 50/50 weight distribution — it doesn't feel top-heavy and one-handed use is genuinely comfortable.
The pure cocoa colorway is OnePlus's first-ever brown finish and stands out next to the standard 15's black/violet/sandstorm options.
Calling a 6.32-inch phone 'compact' just normalizes the new baseline — at this size the only thing keeping it small is OnePlus refusing to make the body any larger, not any genuine effort to shrink the footprint.
r/gadgets commenters reject the compact framing outright — '6.3" screen is NOT compact' is the top reply on the official-first-look thread, with multiple users asking for a true 5.x-inch option.
Display
iPhone 16 Pro Max
A 6.9-inch LTPO OLED with 120Hz ProMotion and ~2,000-nit peak — bigger and excellent, though later models pushed brightness much higher.
The 6.9-inch panel is one reason it's the iPhone to get for a maxed-out feature set — bigger than the 15 Pro Max.
The 120Hz ProMotion display still feels buttery smooth months later and the screen is a daily highlight.
Even against the 17 Pro's 3,000-nit screen, the 16 Pro's ~2,000-nit display is still really decent outdoors.
Owners switching in love how crisp, snappy and premium the display looks.
OnePlus 15T
The 6.32-inch 165 Hz 1.5K AMOLED panel is the only true 165 Hz compact-flagship display on the market and pairs that refresh rate with a measured 1,800 nits brightness, 460 ppi pixel density, Crystal Shield Glass, and HDR10+/Dolby Vision support. Native 165 Hz support in popular FPS games is a real differentiator. Notebookcheck flags 120.7 Hz PWM dimming that can cause eyestrain for sensitive users.
The 6.32-inch 165 Hz AMOLED panel achieves a very good 460 ppi pixel density and the advertised maximum brightness of 1,800 nits in standard measurement.
Display sharpness is plenty competent — sharp, smooth, and easily one of the strongest spec sheets you can get on a compact phone.
Native 165 Hz support in COD, Delta Force and Peacekeeper Elite makes this the only small-screen flagship pushing a full 165 Hz gaming experience.
OnePlus claims up to 3,600 nits peak brightness — even on a playground in direct sunlight you can still see everything clearly, no squinting required.
Specifications confirm a 6.32-inch 1.5K (1216 × 2640) resolution with 165 Hz refresh — a configuration unique to the 15T in the compact class.
Display backlight flickers at just 120.7 Hz under PWM dimming — low enough that the flickering may cause eyestrain and headaches for sensitive users after extended use.
Battery & Charging
iPhone 16 Pro Max
The headline strength: a ~4,685mAh battery delivering the best flagship endurance reviewers had measured — undercut by slow charging.
Battery life is the best of any flagship phone in the last few years — extremely efficient.
In a robotic intensive battery test, the iPhone 16 Pro Max beat all the competition.
Even after a year of daily use it still measured 100% battery health and reached 10h07m screen-on-time in a 7-phone drain test (best result observed: 12h44m on iOS 18.3.2).
It charges slowly: ~39% in 30 min and a full charge in ~2h03m, versus a Galaxy S25 Ultra's 1h17m.
Max wired charge is only ~30W and Apple doesn't even sell a 30W adapter (you must buy the 40W one); MagSafe is 25W.
Heavy users report finishing the day with 40–50% remaining — a huge jump coming from a 15 Pro.
OnePlus 15T
This is the section the OnePlus 15T was built to win. The 7,500 mAh silicon-carbon 'Glacier' cell is the largest ever fitted to a true compact phone — 50% bigger than the iPhone 17's pack in a similar footprint. Notebookcheck measured roughly 1.5 days of real-world endurance at 150 cd/m². Wired charging tops out at 100 W, wireless at 50 W. The only friction points are the missing built-in magnets for MagSafe-style alignment and the still-USB-2.0 port.
OnePlus relies on a silicon-carbon-based battery with a large capacity of 7,500 mAh for its mini flagship — in our practical battery test at 150 cd/m² brightness, the 15T achieved an excellent battery life of nearly 1.5 days.
9to5Google's preview confirms the 7,500 mAh cell carries the same 'Glacier' moniker as the OnePlus 15's battery, so the silicon-carbon structure is here too — 200 mAh more than the larger sibling.
Even though the phone keeps the same compact size, it now packs a massive 7,500 mAh battery — to put that into perspective, the iPhone 17 Pro Max only has around 5,000 mAh, and this is a 6.32-inch phone.
Battery life is wild for a phone this size and is actually a hair bigger than the one in the OnePlus 15, which has a noticeably larger footprint.
Software-support window is uncertain: OnePlus has not committed to a specific update timeline for the Chinese-market 15T, and the global OnePlus 15 already commits to only 4 years of major Android upgrades — well behind Samsung and Google's 7-year promises.
Software-support window is uncertain: OnePlus has not committed to a specific update timeline for the Chinese-market 15T, and the global OnePlus 15 already commits to only 4 years of major Android upgrades — well behind Samsung and Google's 7-year promises.
100W SuperVOOC wired charging and 50W wireless mean even the huge cell refills fast — getting through two full days on a single charge feels totally realistic.
There is no native magnetic Qi alignment — wireless charging works, but accessories require a separate magnetic case for MagSafe-style snap-on functionality.
r/Android's reaction to the battery is unambiguous — 'Incredible battery life makes the compact smartphone competition pale in comparison' is the actual review-thread headline.
