Detailed Comparison
Display
Motorola Razr+ 2023
The 6.9-inch 165Hz LTPO inner panel and 144Hz cover screen are the fastest of any 2023 foldable — both AMOLED, both bright, both class-leading for the form factor.
6.9-inch foldable LTPO AMOLED, 165Hz, HDR10+, 1,400-nit peak — the fastest inner foldable display of 2023.
3.6-inch external AMOLED, 144Hz, 1,100-nit peak, HDR10+ + Gorilla Glass Victus — bright enough outdoors per real-world owners.
Wired: '165Hz refresh rate makes interacting with the cover display feel responsive' — first to ship this refresh rate on a phone in 2023.
Phandroid: 'one of the best smartphone displays for mobile gaming' thanks to 165Hz refresh + AMOLED color.
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.

3,800mAh battery is small — Android Central forum users + reviewers consistently flag battery as the Razr+'s weakest point.
Only IP52 splash resistance (no dust or full water protection) — Galaxy Z Flip 5's IPX8 is meaningfully better protected.
Cameras lack a telephoto and Wired notes they 'don't measure up to the competition' — 12MP main + 13MP ultrawide both trail Galaxy Z Flip 5 in low-light + zoom.
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.
Snapdragon 8+ Gen 1 + 8GB RAM delivers solid 2022-flagship performance — no real-world slowdown for typical use.

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.
Performance
Motorola Razr+ 2023
Snapdragon 8+ Gen 1 + 8GB RAM is last-year flagship silicon — the cost-vs-spec trade-off Motorola chose to ship at $999 vs $1,200+ for an SD 8 Gen 2 device. Real-world performance is excellent for typical use.
Phandroid: 'you're not getting the latest and greatest chipset here since Motorola wanted to price the phone right at $999' — explicit cost trade-off.
Ars Technica: 'not the best you can get from Qualcomm' — the 8 Gen 2 would have been the right chip for a $999 launch.
OnePlus 15T
Snapdragon 8 Elite Gen 5 paired with 12-16GB LPDDR5X Ultra Pro RAM delivers flagship synthetic scores — Notebookcheck recorded Geekbench multi-core 10,976 and 3DMark Wild Life Unlimited 29,901, on par with the larger Xiaomi 17 and Honor Magic8 Pro Air. The problem is sustained: in the 3DMark Wild Life stress test the GPU drops over 50% and the back of the phone hits 50 °C, which both Notebookcheck and SuperSaf flag as a deal-breaker for long gaming sessions.
Geekbench 6 multi-core hits 10,976 — flagship-tier and within 1% of the average 8 Elite Gen 5 result, so there is no compromise on the chipset versus larger phones.
3DMark Wild Life Unlimited hits 29,901 — 5% above the 8 Elite Gen 5 average and ahead of the Xiaomi 17 with the same chip.
In the 3DMark stress tests the OnePlus 15T shows a sharp drop in performance of over 50%, which significantly lowers our rating.
Wildlife Extreme stress test scores swung from 6,990 best loop to 3,743 worst loop in a single run — the chart is 'quite a bit of a bumpy ride' and performance mode did nothing to stabilize it.
Surface temperatures hit 48.3 °C on the back during stress testing and continued climbing to 50 °C near the camera bump — about 45 °C internal — which seems to be the phone's thermal limit.
Genshin Impact averaged 60.3 fps over 30 minutes at just 3.2 W power draw, with the phone staying cool to the touch — and Peacekeeper Elite pushed 164.5 fps thanks to native 165 Hz support.
r/Android's reviewer thread flags the same thermal issue directly: 'Gets kinda hot, over 50 degrees in the corner. This is with its very heavy throttling.'
Battery & Charging
Motorola Razr+ 2023
3,800mAh battery + 30W wired + 5W wireless — Phandroid measured full charge in ~1h 20min. Real-world endurance is the Razr+ 2023's weakest area; Android Central owners consistently flag battery as the biggest pain point.
3,800mAh dual-cell battery — small for the screen size, Android Central owners: 'the worst thing about this is battery.'
30W wired charging full in ~1h 20min per Phandroid — slow vs Galaxy Z Flip 5's 25W (1h 24min) is similar speed but smaller cell helps Motorola.
5W wireless charging only — Stuff notes the Razr+ wired beats Z Flip 5's 25W but loses on wireless (Samsung does 15W).
YouTuber long-term test (Razr 40 Ultra): 'all-day battery achievable for moderate use' with 165Hz refresh + LTPO panel efficiency.
No charger in the box — Razr+ owners must source their own 30W+ USB-C PD brick.
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.

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.
