## Product: Galaxy S25 Ultra
**Brand:** Samsung

Let's talk charging speeds for the Galaxy S25 Ultra, because this is something everyone wants to know before buying.

**The quick specs**: 45W wired, 15W wireless.

**The real-world breakdown**: With a good 45W charger, you're looking at about an hour from dead to full. More practically, you can grab 40% in just 15 minutes if you're rushing out the door. That's solid performance for a phone with a 5000mAh battery.

Here's the thing though. Samsung doesn't include a charger in the box anymore. If you've got an older Samsung charger lying around, it'll work, but you won't hit those top speeds unless it supports 45W. Worth grabbing a proper one if fast charging matters to you.

For wireless charging, you're looking at 15W max. It's not going to win any speed records, but it's convenient for overnight charging or keeping topped up at your desk. One quirk worth knowing: even though it works with Qi2 chargers, the phone doesn't have magnets built in like newer iPhones do. So if you want that satisfying magnetic snap with a MagSafe-style charger, you'll need a magnetic case.

There's also a neat feature called Wireless PowerShare. You can flip the phone over and use it to charge your Galaxy Buds or smartwatch in a pinch. Not super fast, but handy when you're traveling.

**Pro tip**: If you charge overnight and want to baby your battery for the long haul, you can turn off fast charging in the settings. Some people swear it helps battery longevity.
