Capacità Batteria Esatta Samsung Galaxy S26 Ultra (mAh) & Specifiche

Illustrative image, not an official Samsung product photo.
Samsung’s own comparison page lists the Galaxy S26 Ultra with a 5,000mAh battery. That is the exact number readers usually want first, before the rumor mill starts adding and subtracting a few hundred milliamp-hours for drama.
The more useful part is what Samsung pairs with it: 60W wired charging, 25W wireless charging, and Wireless PowerShare. On a spec sheet, that combination tells you more about the phone’s day-to-day feel than the capacity number alone.
If you are comparing the S26 Ultra with the rest of the S26 line, the battery story is simple: the Ultra keeps the largest pack in the family, but it is the balance of battery size, charging speed, and display load that decides how it behaves in real use.
- Battery capacity: 5,000mAh
- Wired charging: up to 60W
- Wireless charging: up to 25W
- Wireless PowerShare: supported
- Position in the lineup: largest battery in the Galaxy S26 family

Exact Samsung Galaxy S26 Ultra battery capacity
The short answer is 5,000mAh. Samsung lists that figure on its official S26 series comparison page, so this is not a leak, a rumor, or a guess pulled from a spec aggregator. It is the number Samsung itself uses when it compares the Galaxy S26, S26+, and S26 Ultra.
That matters because capacity numbers get repeated loosely across the web. Some sites round them up, some list rumor-stage figures, and some bury the real spec under performance talk. Here, the clean answer is enough: the Galaxy S26 Ultra battery capacity is 5,000mAh.
If you only need one line for a buyer sheet or a review note, use that figure and move on. The rest of the story is about what Samsung does with it.

What the charging specs actually change
A battery spec can look flat on paper until you pair it with charging speed. The S26 Ultra’s 60W wired charging changes the way the phone fits into a workday, because it reduces the penalty of a low-battery stop. You are not forced to leave the device parked for long stretches just to recover a meaningful percentage.
Wireless charging at up to 25W is less dramatic, but it still matters if you keep the phone on a desk, stand, or night charger. It is the difference between “slow top-up” and “steady, usable refill,” especially if you tend to top off in short sessions instead of waiting for a full charge cycle.
Wireless PowerShare is the small spec that tends to get ignored. In practice, it gives the phone a secondary role: a quick backup source for earbuds, a watch, or another compatible device when you do not want to hunt for another charger.

Galaxy S26 vs S26+ vs S26 Ultra battery comparison
Samsung’s own lineup makes the battery positioning very clear. The base S26 is the smallest battery option, the S26+ sits in the middle, and the Ultra keeps the largest pack plus the fastest wired charging.
