| The OnePlus 15. |
If you thought the OnePlus 15’s battery was a marathon runner, buckle up. Fresh rumors are painting a picture of the OnePlus 16 as an absolute endurance champion, potentially resetting expectations for flagship smartphone stamina.
Let’s rewind for a moment. The current OnePlus 15, with its impressive 7,300mAh silicon-carbon dual-cell battery, already represents a giant leap forward. In our own rigorous testing, the device achieved a staggering over 66 hours of idle usage on a single charge. To put that into perspective, its predecessor, the OnePlus 13, tapped out at under 38 hours in the same test. Coupled with blistering 120W wired and 50W wireless charging, the bar has been set phenomenally high.
But OnePlus appears ready to vault over it. A new leak from the reliable tipster account @OnePlusClub on X has sent shockwaves through the tech community. According to their post, the OnePlus 16 will debut a "next-gen Glacier Battery" with a mammoth capacity of approximately 9,000mAh.
The leak was first reported in a post by @OnePlusClub, which you can view here.
For context, while brands like Honor have pushed into 10,000mAh territory with models like the performance-focused Honor Win, a 9,000mAh cell in a mainstream flagship like the OnePlus 16 would be unprecedented. This rumored capacity represents a substantial 23% increase over the already formidable OnePlus 15 battery. If true, we could be looking at devices that easily power through multiple heavy-usage days, fundamentally changing how we interact with our phones.
Beyond Battery: A 200MP Camera and Silky-Smooth Display
The leaks don’t stop at pure power. The OnePlus 16 is also tipped to make a monumental jump in imaging hardware. Rumors suggest the inclusion of a 200MP primary sensor, a resolution that would mark a significant upgrade from the OnePlus 15’s camera system. While it remains unclear whether this sensor will serve as the main shooter or a dedicated telephoto lens, the potential for incredible detail and lossless zoom is undeniable. Early speculation hints that the OnePlus 16’s camera architecture might share DNA with the upcoming Oppo Find N6, promising advanced computational photography features.
Furthermore, display enthusiasts have reason to be excited. The OnePlus 16 is rumored to feature a screen with a refresh rate of at least 200Hz, pushing the boundaries of smoothness for scrolling, gaming, and animations beyond the current 120Hz and 144Hz standards.
A Word of Caution and Patience
As with all pre-launch information, it’s crucial to treat these details with cautious optimism. While @OnePlusClub has a solid track record, specifications can and do change during the prototyping phase.
Timeline-wise, expect the OnePlus 16 to follow its predecessor’s schedule, with a likely launch window in Q4 of 2026. If these leaks hold even partially true, OnePlus is not just iterating for its next flagship—it’s preparing to launch a powerhouse focused on eliminating battery anxiety and capturing reality in breathtaking detail. The battle for smartphone supremacy in 2026 is already heating up.
