Here's an irony about the Samsung Galaxy S25 Edge: despite having the smallest battery in the S25 lineup, it takes the longest to charge.

The S25 Edge maxes out at 25W wired charging, which means roughly 75 minutes from dead to full. Meanwhile, the S25 Plus and S25 Ultra both support 45W charging—nearly double the speed—and can fully charge their larger batteries in about an hour.

Why is the Edge slower?

It comes back to that thin design. Fast charging generates heat, and heat needs somewhere to go. The S25 Edge's 5.8mm chassis simply doesn't have enough thermal mass to safely dissipate the heat that 45W charging would produce. Samsung capped it at 25W to prevent overheating.

What this means in practice:

If your phone dies at 3pm and you need to leave by 3:30, a quick 30-minute charge will get you maybe 40-50%. That's less than what you'd get on an S25 Plus in the same time. Combined with the smaller battery that might need charging more often... you see the pattern.

Wireless charging works too:

The S25 Edge supports 15W wireless charging (or Qi2 with a magnetic case). You can also reverse charge your Galaxy Buds or Watch at 4.5W by placing them on the back of the phone. It's slow but convenient in a pinch.

Pro tip: Samsung doesn't include a charger anymore. You'll need to buy a 25W USB-C PD charger separately. Don't bother with a 45W charger hoping it'll charge faster—the phone is limited to 25W regardless of what charger you use.
