Since the first Galaxy Ultra model, all devices in the lineup have used the same battery capacity. So, many fans of these phones have been waiting for improvements in this section for a long time. However, the latest leak about the Galaxy S25 Ultra battery could be disappointing.
The Galaxy S20 Ultra arrived in 2020 with a 5,000 battery. Samsung hasn’t changed this figure since, so even the latest Galaxy S24 Ultra uses a cell with the same capacity. As reported by Digital Chat Station on Weibo and Ice Universe on X, the South Korean giant will keep the tradition on the next-gen model.
Galaxy S25 Ultra may have the same battery capacity and charging support as the S20 Ultra
Not only that, but Samsung would also leave the device’s charging capabilities unchanged. That is, the Galaxy S25 Ultra’s 5,000 mAh battery would support 45W of wired fast charging. The reports do not mention the wireless charging power that the device will support. However, it will probably be the same 15W as the S24 Ultra.
If those numbers look familiar to you, it’s because they’re exactly the same since the Galaxy S20 Ultra. It is possible that the cell has received technological improvements to optimize its operation in new generations. However, the battery capacity and support for fast charging have not changed at all.
Currently, big names in the industry have been stepping up their game in terms of battery capacity for flagship devices. BBK companies (like OPPO and OnePlus) have a 6,100 mAh cell whose thickness is similar to that of 5,000 mAh batteries. So, Samsung would be falling far behind compared to the latest flagship standards in terms of battery and charging.
Samsung would be keeping the same battery capacity for design reasons. The company would be looking to slim down the Galaxy S25 Ultra as much as possible. Leaks claim that the device will be just 8.4 mm thick. However, there are users who would prefer to maintain the current thickness if it means better battery life.
