    OnePlus Developing Flagship Smartphone with 7,800 mAh Battery

    Key Takeaways

    1. OnePlus is developing a flagship smartphone with a potential battery capacity of 7,800 mAh, surpassing the current 6,260 mAh in the OnePlus 13T.
    2. This new device is expected to feature the Snapdragon 8 Elite processor and a flat display.
    3. OnePlus has a unique naming convention in China, likely leading to the new phone being called the OnePlus 15.
    4. Advancements in silicon-carbon battery technology allow for larger batteries to fit in smaller devices by storing more electrons in the same space.
    5. The OnePlus 13T uses a silicon-carbon battery but doesn’t fully qualify as a flagship, indicating the upcoming device will have enhanced features and specifications.

    With the rise of silicon-carbon batteries in the smartphone world, manufacturers can now fit bigger batteries into smaller devices. The OnePlus 13T exemplifies this trend with its impressive 6,260 mAh battery. Now, it seems that OnePlus is developing a flagship model that could feature an even bigger battery capacity of 7,800 mAh.

    Latest Info from Weibo

    Recent information has surfaced from Digital Chat Station on Weibo, revealing that a new flagship phone powered by the Snapdragon 8 Elite is in the pipeline. This upcoming phone is expected to boast a battery around 7,800 mAh, complete with a flat display. While the leaker did not specify OnePlus, many commenters believe this device will be the next in line, possibly the OnePlus 14 or 15.

    Naming Conventions in China

    OnePlus has a unique approach to its naming system, particularly in China, where they skip the number 4 (the OnePlus 4 was never released, and the Nord 4 was branded as Ace 3V). Therefore, it seems probable that the new phone will be called the OnePlus 15.

    Advancements in Battery Technology

    The ability to fit such a large battery in a smartphone is largely thanks to advancements in silicon-carbon technology. This new type of battery replaces traditional graphite ones, allowing for more electrons to be stored in the same space. This means that while the phone’s size remains compact, the battery capacity can increase dramatically.

    The OnePlus 13T currently uses a silicon-carbon battery, which enables a 6,260 mAh capacity within a smaller chassis and a 6.32-inch display. It is powered by the Snapdragon 8 Elite SoC but doesn’t fully qualify as a flagship since it lacks the top-tier camera system, display quality, charging speeds, and wireless charging found in the OnePlus 13. The device mentioned in the latest leak is labeled as a flagship, suggesting it is indeed the OnePlus 15, rather than a ‘T,’ ‘R,’ or ‘Ace’ variant.

  • Galaxy S26 Series Expected to Use Silicon-Carbon Battery Technology

    Galaxy S26 Series Expected to Use Silicon-Carbon Battery Technology

    Consumer electronics have been relying on lithium-ion (Li-ion) batteries for more than ten years. Recently, Chinese smartphone manufacturers have adopted a new battery technology: the silicon-carbon anode battery. This innovation has allowed foldable phones to become as slim as traditional bar phones when closed, and bar phones to shrink back to 6.3 inches, all while holding larger batteries than the 6.8-inch Galaxy S24 Ultra.

    Samsung’s Upcoming Changes

    There are rumors that Samsung will begin using this new battery technology with the Galaxy S26 series next year. For those who may not be aware, silicon anode batteries have a significantly higher energy density than the conventional Li-ion batteries that smartphone makers have traditionally employed. This boost in energy density enables manufacturers to create sleeker designs without compromising battery life.

    Previously, it was suggested that Samsung was developing a different battery technology known as “Stacked Battery Technology,” which could enhance energy density by 10%. By implementing this stacking method, energy density might rise by more than 10%. For instance, a battery with a capacity of 5,000mAh in the latest Galaxy S Ultra could potentially increase to over 5,500mAh with stacking. However, it appears that Samsung has opted for the silicon-carbon battery technology instead.

    Battery Capacity for Galaxy S25 Slim

    If you’re curious, there’s no confirmation about the use of this technology in the upcoming Galaxy S25 Slim. A recent report indicates that both the S25 Slim and Apple’s iPhone 17 Air will have batteries with a capacity ranging from 3000 mAh to 4000 mAh. Currently, Samsung’s Ultra flagship boasts an impressive battery life, thanks to its 5000mAh capacity. It will be intriguing to see how much the Galaxy S26 Ultra’s battery capacity and life improves with the new silicon-carbon anode battery technology.

    That said, the Galaxy S25 series is rumored to maintain the same battery capacity as the previous models. Nevertheless, the more efficient Snapdragon 8 Elite chipset is expected to provide a slight enhancement in battery life compared to last year’s devices.
