Samsung launched three new flagship smartphones today: Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra. Each model caters to different user preferences. The base S25 offers a compact design with a few compromises, while the Ultra delivers the best of everything in a large form factor. The Plus model provides a middle ground between the two. If you are wondering about their battery capacity and charging speed, here’s the breakdown.
Galaxy S25 Ultra battery capacity and charging speed info
Samsung slimmed down its flagship lineup this year, with all three models coming 0.4mm thinner than their respective predecessors. The Galaxy S25 phones are also lighter, with the S25 Ultra weighing 15 grams less than the S24 Ultra. Despite this, Samsung retained the screen size, even offering a marginally larger display on the new Ultra. This is all thanks to reduced bezels, giving the devices a more premium front design.
Unfortunately, these design enhancements mean Samsung had little room for a battery boost. In fact, it couldn’t increase the battery capacity over the 2024 models. All three Galaxy S25 models pack the same battery capacity as their predecessors. We are talking about a 4,000mAh battery on the base model, 4,900mAh on the Plus, and 5,000mAh on the Ultra. 4,000mAh might sound too little to some, but it’s a pretty small and lightweight phone.
More importantly, the Galaxy S25 series features a more efficient 3nm Snapdragon 8 Elite processor. Coupled with efficiency gains from the display and One UI 7’s enhanced power management features, we should get a longer battery life. Not a huge boost, but the new flagships should deliver a better battery backup than the S24 lineup.
Samsung needs to step up its charging game — and the sooner, the better
While we won’t complain about the Galaxy S25’s battery capacity, Samsung’s decision to stick with the same charging speed leaves much to be desired. Yes, the company hasn’t upgraded its flagship charging speed this year either. The base model, in particular, should have been upgraded to at least 45W charging. While 45W isn’t groundbreaking in 2025, offering just 25W on a flagship device feels outdated and hard to justify.
The 15W wireless charging also remains unchanged. While the entire Galaxy S25 series supports Qi2 wireless charging, it requires a case. The phones themselves do not feature built-in magnets, so a case is a must for Qi2-enabled accessories and magnetic alignment.
