OPPO has released the mid-range OPPO Reno15 A in Japan on June 25. It packs the largest battery in the series, a 7,000mAh cell, along with 80W fast charging, into a body just 8.1mm thin. The phone also offers a 50MP front camera, water and dust resistance up to IP69, and support for Osaifu-Keitai (FeliCa), with the SIM-free model starting at 64,800 yen. It is a phone that quietly covers the features that matter in everyday use.

A Series-Best 7,000mAh Battery with 80W Fast Charging

The Reno15 A's standout feature is its 7,000mAh battery. While most mid-range phones top out around 5,000mAh, this one fits a far larger cell into a slim 8.1mm body. The capacity is about 20 percent larger than the previous OPPO Reno13 A, and OPPO says it lasts about 2.5 days based on a test assuming roughly 6 hours of use per day. That figure is a manufacturer measurement, so real-world endurance will vary with usage and network conditions.

Charging covers 80W SUPERVOOC fast charging plus 55W PPS fast charging. The Reno15 A is also the first in the Reno A series to support bypass charging: when you play games or watch videos while plugged in, power is fed directly to the phone rather than through the battery, which helps curb heat-related slowdowns and battery wear. Because the large battery still tops up quickly, its size is unlikely to feel like a drawback.

A 6.6-inch OLED and a Rugged, Water-Resistant Body

The display is a roughly 6.6-inch OLED panel with a Full HD+ resolution of 2,372 x 1,080 and a 120Hz refresh rate. Peak brightness reaches 1,400 nits, keeping the screen readable even in bright outdoor light. A slim bezel design pushes the screen-to-body ratio to 92.8 percent, and the surface is protected by Dragontrail Star D+ glass. Biometric options include both an in-display fingerprint reader and face unlock.

Durability is another highlight. The phone meets both IP68 and IP69 ratings, withstanding submersion in fresh water as well as high-pressure jets of hot water. It is rare to see this level of protection at this price. It also supports splash touch for use with wet hands and a glove mode. On top of that, it handles Osaifu-Keitai (FeliCa) and My Number Card functions, and accepts microSD cards up to 1TB, covering the conveniences Japanese users expect.

Snapdragon 6 Gen 1 and New OPPO AI Features

The chip is Qualcomm's Snapdragon 6 Gen 1, built on a 4nm process. It is not aimed at top-tier performance, but it comfortably handles everyday tasks, video streaming, and lighter games. Memory comes in 8GB and 12GB options, paired with 128GB or 256GB of storage, and a RAM expansion feature can borrow part of the storage to act as memory. The OS is ColorOS 16, based on Android 16.

On the software side, the lineup of OPPO AI features grows. AI Mind Space automatically sorts and saves scattered information such as screenshots, memos, and web pages so it can be pulled up again when needed. AI photo editing can correct blur and dark exposure, cleaning up shots after they are taken.

A 50MP Front Camera Built for Selfies

The front camera steps up to roughly 50MP and adds an ultrawide field of view of about 100 degrees. Beyond the jump in image quality, that makes it easier to fit several people into a group selfie or to capture a wide landscape together with yourself. On the back is a triple-camera setup combining a 50MP main sensor with optical image stabilization (OIS), an 8MP ultrawide, and a 2MP macro.

Price and Availability

The SIM-free model is priced at 64,800 yen for the 8GB+128GB version and 76,800 yen for the 12GB+256GB version. Three colors are offered: Aurora Blue, Twilight Navy, and Afterglow Pink. Distribution is broad, spanning carriers such as UQ mobile, Y!mobile, and Rakuten Mobile, low-cost SIM providers like mineo and IIJmio, electronics retailers, and online stores including the OPPO official store. Pricing varies by retailer and can be combined with each company's plans and discount programs. The UQ mobile version also supports au Starlink Direct, which connects directly to satellites.

The wider Reno15 series reached parts of Europe in early 2026, but this Reno15 A is a model aimed squarely at the Japanese market.

Summary

The OPPO Reno15 A bundles the features that pay off in daily use, a 7,000mAh battery, 80W fast charging, IP69 water and dust resistance, and a 50MP front camera, into a mid-range phone starting at 64,800 yen. Rather than chasing flagship processing power, it invests in battery life, ruggedness, and easy selfies, making it a sensible choice for anyone looking for a phone they can rely on for the long haul.
