Samsung will once again retain a 5,000mAh battery on its Galaxy S26 Ultra, meaning that it will rely on more efficient hardware and optimized software to deliver better runtime than its immediate predecessor, the Galaxy S25 Ultra. Thankfully, the company will finally lift the fast charging blockade that it placed on its top-end flagships for generations, as the latest leaked code reveals that an upgrade is finally lined up for the Galaxy S26 Ultra.
New leak reveals the Galaxy S26 Ultra will support 60W charging, confirming the previous rumor, but the lack of a battery upgrade will disgruntle future buyers
Despite Samsung reportedly exploring silicon-carbon technology to increase the battery size of its smartphones, we previously learned that the Galaxy S26 Ultra will continue to ship with a 5,000mAh cell, a size that has yet to change for several generations. Fortunately, a rumor was doing the rounds, stating that instead of 45W charging support, Samsung will finally implement 60W wattage on the Galaxy S26 Ultra, which will top up the battery at a faster rate.
Then again, rumors can be dispelled if there is little to no concrete proof, but leaked code posted by Erencan Yılmaz on X confirms that Samsung is bringing 60W charging support to the Galaxy S26 Ultra. Two lines can be seen in the post below, and you can clearly read the term ‘60W,’ which pretty much confirms that we are getting a much-needed specifications change early next year.
There is no information surrounding what the rest of Samsung’s Galaxy S26 family will support when discussing the maximum wattage support, but this is a step in the right direction. As for how Samsung intends to improve battery life while retaining the same capacity, an executive stated that the company leveraged agentic AI on the Galaxy S25 Edge to improve efficiency, so the same approach could be applied to the Galaxy S26 Ultra.
However, there is only so much that software can accomplish before the hardware becomes the limiting factor and we hope that Samsung finally jumps on the silicon-carbon bandwagon to keep pace with its Chinese competitors.
