Detailed Comparison
Design & Build
Motorola Razr+ 2024
A genuinely distinctive clamshell — high-quality case, narrow bezels, fresh-water submersion protection and eye-catching finishes (including the Mocha Mousse and vegan-leather backs). Widely called a design leader.
Highly performant with good cameras, solid software and a striking design that keeps the Razr Plus a design leader heading into 2025.
A high-quality case with a huge external display, narrow bezels and protection against submersion into fresh water.
Owners coming from iPhone say 'Love what Motorola has done and IMO it's better than the Z Flip 6.'
Notebookcheck's caveat: despite the quality case, it 'lacks some premium features' for its ~$1,000 price.
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.

The camera is only 'good' / underwhelming for a ~$1,000 phone, and Motorola dropped the ultrawide for a telephoto.
Battery life, while good for a flip, is still significantly weaker than conventional slab phones at this price.
The Snapdragon 8s Gen 3 is a step down — small CPU gains and even a graphics-performance drop versus the previous Razr+.
Long-term durability is a recurring concern across the Razr folding line — screen lines and hinge wear from daily folding, plus slow update delivery.
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.

No built-in MagSafe-style magnets — wireless-charging accessories require a separate magnetic case to align properly.
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.
Performance
Motorola Razr+ 2024
The Snapdragon 8s Gen 3 delivers flip-flagship-level everyday performance, but it's a step down from a true flagship chip — small CPU gains and even a graphics-performance regression versus the prior Razr+.
Performance is absolutely on the level expected from a flip flagship for day-to-day use.
Motorola cut back on the SoC — only small performance gains and even a drop in graphics performance versus last year's Razr+.
It comes with significantly more storage than last year — a meaningful generational upgrade.
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+ 2024
Battery life is very good for a flip foldable and improved over the Razr 40 Ultra (more capacity + a more efficient chipset), with a fast 45W charger included — but it's still weaker than conventional slab phones at the price.
Battery life is very good — helped by ~200mAh more capacity than the Razr 40 Ultra and a more efficient chipset.
Motorola includes a rapid charging brick in the box that refuels at the phone's max 45W (and can supply 68W to other hardware).
Battery life improved, but is still significantly weaker than conventional (non-folding) phones in this price range.
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.
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.
Software & AI
Motorola Razr+ 2024
A light-touch, near-stock Android with handy Moto gestures and an excellent cover-screen Panels UI — and the first phone to ship with Gemini out of the box. The recurring negative is Motorola's slow update cadence.
A light-touch approach to Android — handy gestures and features tucked into a dedicated customization app, with the more dramatic changes off by default.
It's the first phone to ship with Google's AI-powered Gemini out of the box, including a few months of the advanced tier.
Motorola's Panels UI now supports almost any app on the exterior display — turning the cover screen into a genuine secondary device.
Update delivery is slow — Motorola only updated the Razr+ (2024) to Android 15 in late April 2025, and historically caters to the India market first.
Moto-specific touches like double-chop for flashlight and double-twist to open the camera are genuine daily-use wins for switchers.
OnePlus 15T
The OnePlus 15T ships with ColorOS 16 on Android 16 in China rather than the global OxygenOS, though the two skins are now nearly identical in feel. Update commitments are unclear — OnePlus doesn't publish a timeline for Chinese-market hardware, and even the global OnePlus 15 only commits to 4 years of major Android upgrades. Mind Space (AI-powered productivity vault) and Gemini integration are the headline software features.
ColorOS 16 comes pre-installed on the 15T instead of OxygenOS — but the differences are minor overall, with German language and Android Auto supported, though no WearOS watches or eSIMs.
There are question marks over the duration of the updates provided — the manufacturer does not usually provide any information on this for China, though typically a OnePlus 15-class phone should receive security updates for six years.
OxygenOS 16 (and ColorOS 16 by extension) integrates Gemini with Mind Space — you can ask Gemini about any saved memory and it accesses local content to perform tasks, making it the best on-phone AI integration we have seen.
Mind Space is the headline AI feature — a digital vault that takes a screenshot of important content and saves it as a card with URL, summary, title and hashtags for contextual search.
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.

The system feels incredibly smooth — arguably one of the best experiences you can get on Android right now, with useful features for students like meeting summaries and lecture transcription.
Update commitment trails the competition — even on the global OnePlus 15 the company only promises 4 years of major Android upgrades, well behind Samsung and Google's 7-year commitments.
