The OnePlus 15 charges ridiculously fast. Like, "go take a shower and come back to a full battery" fast.
The phone supports 120W wired charging (80W in the US due to regulations), which fills the massive 7,300mAh battery in about 45 minutes. The charger comes in the box, so you get this speed right out of the gate without buying anything extra. That's becoming rare with flagship phones.
For wireless charging, you're looking at 50W speeds with OnePlus's special AIRVOOC magnetic charger. That charger has a built-in fan to keep things cool, which is a nice touch. It's sold separately though. Standard Qi wireless charging works too, just at slower speeds.
Here's something to know: the OnePlus 15 doesn't support Qi2 magnetic charging. Even if you buy a magnetic case, you can't enable Qi2. OnePlus basically said "we'd rather have a bigger battery than magnets," which is a fair trade-off honestly. You can still use magnetic accessories through cases with built-in magnets, but true Qi2 isn't happening.
The charging speed advantage over competitors is huge. The Samsung Galaxy S25 Ultra? 45W wired, 15W wireless, and it takes 69 minutes to fully charge a smaller battery. The OnePlus 15 runs circles around it in charging performance.
One feature gamers should know about: bypass charging. When you're gaming while plugged in, the phone can power itself directly instead of charging the battery. This keeps things cooler and doesn't stress your battery. If you're the type to game for hours while plugged in, definitely turn this on.
Bottom line: charging anxiety isn't a thing with this phone. Between the massive battery and the fast charging, you're covered.
