    Galaxy S25 Ultra teardown suggests a Bluetooth S Pen isn’t an impossibility

    A teardown video of the Galaxy S25 Ultra has emerged through the YouTube channel JerryRigEverything, revealing some interesting and even slightly confusing details about the phone's insides.

    The video previews the internal components, such as the 40% larger vapor chamber that keeps the powerful Snapdragon 8 Elite chip cool.

    The Galaxy S25 Ultra is also easier to repair, at least judging by the way the battery is fitted inside. Last year, Samsung made the Galaxy S24 Ultra's battery easier to remove by giving it a pull tab, but this year, the Galaxy S25 Ultra takes it one step further.

    Instead of sticking the battery to the phone's chassis with adhesive and adding a pull tab for easier removal, Samsung has done away with the adhesive from the Galaxy S25 Ultra's battery. The unit sits inside a pouch but isn't glued to it.

    Another interesting detail lies inside the Galaxy S25 Ultra's upper speaker. It now has a small foam ball chamber, which may help increase the volume and bass. The Galaxy S24 Ultra's upper speaker didn't have this component, so it might explain why the Galaxy S25 Ultra sounds noticeably better than its predecessor.

    There's still an S Pen coil inside the Galaxy S25 Ultra

    The more confusing detail this Galaxy S25 Ultra teardown revealed relates to the S Pen. The iconic accessory has been a hot topic since Samsung confirmed it doesn't have an internal battery or support for Bluetooth-based Air Actions features.

    Because these features were missing, we assumed that the internal coil inside the Galaxy S25 Ultra — the one meant to recharge the S Pen — also got removed. This new teardown video by JerryRigEverything reveals otherwise.

    Samsung hasn't removed the S Pen charging coil from inside the Galaxy S25 Ultra. It exists physically inside the phone, however, it's unclear if it still has charging capabilities. It might be used solely to detect when the S Pen is inside its holster and could lack the ability to recharge an S Pen's battery.

    Not that there is a way to test this. The Galaxy S24 Ultra S Pen barely fits inside the Galaxy S25 Ultra but doesn't click in, and the 2025 flagship doesn't recognize it.

    Assuming that the S Pen coil is still technically capable of recharging an S Pen, this may be an indication that a battery-powered Bluetooth S Pen for the Galaxy S25 Ultra could be released at some point, JRE suggests. However, at the moment, the presence of the charging coil is in no way proof that Samsung has any such plans.

    In any case, it doesn't seem like Samsung managed to make the Galaxy S25 Ultra thinner and narrower because of the removal of unnecessary S Pen components. Rather, Samsung may have used the internal space more efficiently, resulting in a smaller phone with a slightly larger screen than the 2024 model.
