A lot of interesting stuff has leaked about the upcoming Samsung S27 lineup, especially regarding its Ultra variant. For instance, the surfaced renders suggest that the device will come with an iPhone-inspired horizontal camera module on the back.
But one particular detail that has got me excited about the Galaxy S27 Ultra is that it is believed to be slightly heavier than the Galaxy S26 Ultra. Well, it may not seem so, but it's actually great news. Allow me to explain why.
Ice Universe recently made a post on X revealing the dimensions and weight of the Galaxy S27 Ultra. According to the prominent tipster, the device will weigh 218 grams.
For comparison, this is 4 grams more than the Galaxy S26 Ultra, which weighs 214 grams. Interestingly, last year's Galaxy S25 Ultra also weighed 218 grams.
Which Galaxy S27 Ultra reported change are you most excited about?

It might be confirmation for a bigger battery
Samsung has been offering a 5,000 mAh battery in its Ultra model for the last several generations. This number not only looks minuscule for a device that costs $1,300 but also puts the phone behind some of its main competitors, such as the iPhone 18 Pro Max, Pixel 11 Pro XL, and Xiaomi 17 Ultra, in terms of raw battery capacity. For reference, the iPhone 18 Pro Max features a 5,391 mAh battery, the Pixel 11 Pro XL has a 5,115 mAh cell, and the smartphone from Xiaomi comes with a massive 6,000 mAh battery capacity.

The good news for Galaxy fans is that the Galaxy S27 Ultra is rumored to feature a bigger battery, with many reports claiming it will be around 5,700 mAh. So, it's quite possible that the weight increase might be because of the use of a bigger battery in the premium phone, ultimately confirming that Sammy will finally move on from the 5,000 mAh mark for its Ultra phones.
Will it be a silicon-carbon battery?
Possibly not, and the reason behind this is also the increase in the device's weight. You see, one of the main characteristics of silicon-carbon technology is that it allows more energy to be packed into the same volume. So, if the increase in the device's weight is indeed because of a bigger battery, then Samsung is most likely not using the latest battery technology, because if it were, the company would have been able to offer a larger cell capacity without increasing the phone's weight.
The Galaxy Z Fold 8 and the Z Fold 8 Ultra are the first devices from Samsung to feature silicon-carbon batteries. The tech giant has recently made it clear that although its new foldables feature the latest battery technology, whether or not it will be used in upcoming Galaxy phones will totally depend on the customer experience with the new technology.
A massive battery is what everyone want

One of the biggest complaints users have about Samsung is that its phones come with average battery capacities, especially compared to what you get in some of its Chinese competitors. Online community forums are filled with comments and posts from users calling out Sammy for lagging behind in the battery department. Under a Reddit post that basically talks about the changes the S27 lineup should come with, most comments talk about a bigger battery.
A user commented that if the upcoming S line phones come with a cell capacity of around 7,000 mAh, they would be the first in line to buy the device. Another user mentioned that the tech giant should offer faster charging along with a silicon-carbon battery of 7,000 mAh.
The price increase seems justified
A recent report gives an idea of what could be the price of the upcoming Samsung phones. According to it, the Galaxy S27 Ultra could start from $1,399, and I, personally, would be more than happy to give $100 more for a bigger battery. The good part is that the battery isn't the only department the upcoming premium phone is expected to see an upgrade in.
All these changes are really making me excited about the Galaxy S27 Ultra and suggesting that it is really going to be one of the best flagships of 2027.
