OnePlus has introduced the 15R 5G, and you can’t miss the showstopper – a huge 7,800mAh battery that is the largest seen in a OnePlus device to date. While many smartphones continue to struggle in balancing power with battery life, the 15R 5G breaks the mould and brands itself the “Battery Beast” for anyone who games, creates, or uses their phone as an actual beast of a device.
The phone will charge at 120W SUPERVOOC fast charging to provide hours of use from just minutes of charge—the expectation is the battery can go from 0-100% in-under 30 minutes—making it one of the fastest to charge in its class.
Designed with Gamers in Mind: Power + Performance
For mobile gamers in particular, the OnePlus 15R 5G comes with a cooling system designed for high-efficiency use cases, an upgraded vibration motor, and general engineering to accommodate long gaming sessions.
With a battery this large, users will feel less stress about battery charging, especially during those intense online games or long streams.
The device likely uses what will be the latest Snapdragon chipset in the segment, and potentially utilises some high refresh rate display options (likely 120Hz or 144Hz). These upgrades have the entire package designed with performance in mind, and target casual or hardcore gamers where required.
Large Battery, Small Footprint?
A 7,800mAh battery immediately raises questions about weight and what it will feel like to hold. My first impression is that OnePlus has been able to distribute the weight well, and the device will be reasonably comfortable in hand.
OnePlus’s goal here is to offer all-day longevity without making you feel like you’re holding a brick. That focus will help deliver a fantastic experience for travellers and anyone spending a long time outdoors, focusing on long battery life instead of tapering functionality.
Great for Content Creators as Well With AI Editing Features
Although not designed for the use case, the large battery and capable hardware should represent a good option for creators who use smartphones to film video content, edit video content with AI features, or livestream.
Battery drain is often a pain-point while recording in 4K, or when utilising a smartphone while editing videos for long periods – at least to some degree, the 15R’s large cellular battery will diminish those pain-points.
Is It A Game-Changer?
In addition to an oversized battery, fast charge, and performance-based benefits, the OnePlus 15R 5G represents a point of contact for a competitive mid-premium smartphone space – one that is crowded and still filling out in terms of options.
Especially if you are an avid gamer, binge-watcher, or heavy multitasker, the OnePlus 15R 5G is a compelling upgrade or a defined starting point – it could represent the gold standard for battery-focused smartphones in 2025.
