Thus, the battery would be more compact, which would allow the Galaxy S26 ultra to be finer and lighter than its predecessor.
In parallel, the leak also mentions new features on the quick charge side, just to offer users the possibility of regaining more quickly in autonomy. More specifically, new technology would reduce temperatures during recharging, allowing to benefit from a power of 65 W on the Galaxy S26 Ultra, against 45 W on the Galaxy S25 Ultra.
