iQOO 15R Review: Flagship Chip, Marathon Battery — The Gaming Phone That Thinks It’s a Work Phone

The iQOO 15R launched in Malaysia on at early March 2026 at the price of RM2,499 — positioned as THE gaming phone, wearing gaming phone marketing, and built around a chip that sits at the top of the Android performance hierarchy. Snapdragon 8 Gen 5, 144Hz AMOLED display, 7600mAh silicon anode battery, 100W charging. The spec sheet does not leave much to the imagination.

But after several days of hands-on testing — including sustained gaming sessions, a full PCMark battery rundown, camera work across conditions, and living with OriginOS 6 from a fresh setup — the most interesting finding about this phone is not what it does for gamers. It is what the 7600mAh battery does for everyone else.

Key Specifications

What We Like About the iQOO 15R

1. A Battery That Redefines the Category

The headline number is 7600mAh. The number that actually matters is 17 hours.

Running PCMark Work 3.0 — a standardised battery benchmark that simulates real productivity workloads including web browsing, document editing, and video playback, at full brightest — the iQOO 15R ran for 17 hours before dropping to the 20%.

That is not gaming phone performance, this has surpassed flagship work phone performance of flagship level smartphone like the Samsung Galaxy S25 Ultra and the iPhone 16 Pro Max territory only at mere RM2,499.

The silicon anode chemistry that makes 7600mAh possible in a 7.9mm chassis has been explained in detail in our companion explainer. What the test result confirms is that the engineering claim translates to real-world endurance. For a Malaysian buyer — long commutes, all-day use, irregular access to power points — this phone answers the battery anxiety question more completely than anything in this price bracket.

📊 Real test result: 17 hours to 20% on PCMark Work 3.0  with full brightness. For context, most RM2,000–3,000 Android phones hit 10–13 hours on the same test.

2. Gaming Performance That Holds Its Temperature

A full 25-minute MLBB session produced a 3 percent battery drain. Three percent. In 25 minutes of continuous gaming at competitive settings. The 7600mAh cell and the Snapdragon 8 Gen 5’s efficiency advantage on 3nm fabrication compound each other in exactly the way the spec sheet implies they should.

More interesting was the thermal behaviour. During sustained play, heat generation at the grip area was minimal — the 6.5K IceCore VC cooling system is actively redirecting thermal load away from where your hands sit. The vapour chamber is doing its job. The phone gets warm at the back where you can feel it, but the grip zones stay comfortable through a full session. For Malaysian players who game in warm rooms without air conditioning, this matters more than the benchmark score.

Bypass charging during gameplay worked exactly as iQOO claims. Plugged in mid-session at low battery, the frame rate held without dipping. The phone ran slightly warmer than on battery alone, but not dramatically so. The Global Bypass Charging 2.0 system — routing power directly to the processor during high load rather than through the battery — is not a marketing footnote. It functions.

🎮 Gaming note: MLBB 25-minute session: 3% battery drain, minimal grip-area heat. Bypass charging confirmed: no frame rate dip while charging under load.

3. A Display That Handles Malaysian Sun

The 5000 nit peak brightness claim is real in daily use. Under direct Malaysian midday sun — full outdoor exposure, no shade — the iQOO 15R’s screen remained comfortable to read. This is not a given at any price point. Budget phones frequently claim high brightness figures that do not hold outdoors. The 15R delivers.

The 1.5K AMOLED panel with 144Hz refresh and 4320Hz PWM dimming also holds up at the other end of the brightness range. Tested at low brightness in a dark room, no perceptible flicker was observed. The high PWM frequency achieves its stated purpose. Worth noting: as an optician, we still do not recommend extended viewing in dark environments at low brightness, but the hardware is doing what it can to reduce strain.

4. IP68 + IP69 — The Best Water Resistance in This Bracket

Most phones at this price carry IP68. The iQOO 15R adds IP69 — resistance to high-pressure, high-temperature water jets, not just submersion. In a country where sudden downpours are a daily weather event, the dual rating is a genuine differentiator over competitors that stop at IP65 or IP68. It is a spec that buyers rarely remember until the moment they need it.

5. Performance Credentials That Outlast the Competition

The Snapdragon 8 Gen 5 is a full chip generation ahead of other competitors in the market, most of which run Snapdragon 8 Gen 3. In practical terms for the buyer who is keeping this phone for two to three years: the 15R will handle the next two or three years of increasingly demanding mobile games — and the Android apps that grow with them — with headroom. The Gen 3 phones are still capable today. The question is 2027 and 2028, and the Gen 5 answers it more confidently.

What We Don’t Like About the iQOO 15R

1. OriginOS 6 Arrives as a Bloatware Minefield

Fresh out of the box, OriginOS 6 is a mess. Pre-installed apps span iQOO’s own gaming tools, vivo services, regional additions, and third-party placements that most buyers will never use. The first hour with a new iQOO 15R is spent clearing apps you did not ask for — a ritual familiar to anyone who has bought a Chinese Android phone in Malaysia, but no less frustrating for being expected.

The good news is that the bloatware is clearable. With housekeeping done, OriginOS 6 is a genuinely capable Android skin with a well-engineered gaming layer. The bad news is that the first impression it makes on a buyer who does not know what they are walking into is not a good one. iQOO can and should do better here.

2. The Gaming Suite Has No FPS Counter

This one is genuinely puzzling. The iQOO 15R ships with one of the most complete gaming suites available on any Android phone — Monster Mode, Predictive Scheduling, 4D vibration, Game Live Streaming, bypass charging intelligence. It is a comprehensive toolkit. And then it does not include an FPS counter.

An FPS counter is the single most useful tool for a competitive mobile gamer. It tells you whether your settings are actually delivering the frame rate you are targeting. Its absence in a phone marketed specifically at gamers, at RM2,499, is an oversight that an OTA update could fix but should not have shipped without. Competitive MLBB and PUBG Mobile players will notice immediately.

⚠️ Missing feature: No native FPS counter in the gaming suite. Players will need a third-party solution. This should be a Day 1 OTA fix.

3. The Camera’s Colour Science Is a Personal Divide

The 50MP Sony LYT-700V delivers clean results in both well-lit and low-light conditions. It works well enough as a daily camera — sharp, reliable, handles the lighting conditions Malaysian buyers actually shoot in.

The 2x lossless zoom is honest: it feels like a high-resolution digital crop rather than optical zoom, but with no moving parts in the camera module, the result is better than you would expect from the spec on paper.

The issue is colour processing. The NICE algorithm from vivo’s flagship models tends toward warm, saturated rendering that not everyone will prefer. Skin tones can skew orange in warm lighting.

Foliage leans into greens more aggressively than reality. If you are a pixel-peeper who cares about colour accuracy, the camera will frustrate you. If you are a gamer buying this phone primarily for gaming and the camera is secondary, it will not. The expectation-setting matters here: this is a gaming phone with a serviceable camera, not a camera phone that games.

The 8MP ultrawide is functional but unremarkable — a supporting act that gets the job done without distinction.

4. USB-C 2.0 Is a 2026 Anachronism

The port on the bottom of the iQOO 15R carries the same data transfer standard as a phone from 2015. USB-C 2.0 maxes out at 480Mbps — a practical transfer rate that makes moving large files to a laptop noticeably slow. Transferring a 4K video file from the 15R to a computer via cable will take meaningfully longer than the same transfer on a phone with USB 3.2 or higher.

For a buyer who manages their phone’s content exclusively through cloud services or wireless transfer, this will never surface as a problem. For a buyer who cables up their phone to a computer for file management, video editing, or game recording exports, the limitation is real and daily. It is a cost-saving measure that sits awkwardly on a phone at this price point.

Conclusion

The iQOO 15R was supposed to be the gaming phone that Malaysian players had been waiting for. And it is. But the more interesting story is what it is beyond that.

A 17-hour PCMark battery result does not describe a gaming phone. It describes a phone that outlasts your day — your commute, your meetings, your gaming session, and your evening scroll — and still has charge left to spare. That endurance, combined with a Snapdragon 8 Gen 5 that runs cool and charges without frame rate compromise, makes the iQOO 15R the most complete package in its price bracket regardless of use case.

The gaming credentials are genuine. The thermal management during MLBB was excellent. Bypass charging worked exactly as claimed. The display holds up under Malaysian sun in a way that budget phones routinely fail to. IP68 plus IP69 is the best water resistance in this bracket.

The honest caveats are real. OriginOS 6 ships in a state that requires work. The missing FPS counter is an inexplicable gap in an otherwise comprehensive gaming suite. The camera colour science will divide opinions. USB-C 2.0 feels out of place at this price in 2026.

None of those caveats define the daily experience for the buyer this phone is built for. At RM2,499, the iQoo 15R offers a chip generation advantage over every competitor in its bracket, a battery that genuinely changes how you use a phone, and gaming performance that holds up under real Malaysian conditions. That combination earns it the HelloExpress Gold Award.
