Charge time by charger wattage
| Charger | Power | Full charge (0-100%) |
|---|---|---|
| Basic charger | 5W | 4 h 12 min |
| Standard fast charger | 25W | 50 min |
| Ultra fast charger | 45W | 28 min |
Battery capacity: 14.85 Wh · Chemistry: li-ion
Modern devices negotiate power with USB-C PD or a proprietary fast-charge protocol, so plugging into a higher-wattage charger is safe: the device itself decides how much power to draw.
Expect anywhere from a lunch break to a couple of hours, depending on the charger you use.
With the fastest charger listed here (Ultra fast charger, 45W) it takes about 28 min. With the slowest (Basic charger, 5W) it takes about 4 h 12 min. Samsung's Galaxy S23 features a 3900 mAh battery that supports 25W fast charging.
Frequently asked questions
- How long does it take to charge a Samsung Galaxy S23 Battery?
- From 0% to 100% with the standard 25W charger, it takes about 50 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Can I use a higher-wattage charger to charge it faster?
- Yes, as long as the charger is compatible with the device's connector and voltage. The battery's own charge controller limits how much current it accepts, so a more powerful charger reduces time mainly in the 0-80% range; above 80% lithium-ion packs taper the charge rate for safety regardless of charger wattage.
- Why does charging slow down near the end?
- Lithium-ion batteries charge at full power up to about 80%, then switch to a slower "taper" phase that protects the cells from stress at high voltage. That's why the last 20% often takes nearly as long as the first 80%.
- How is this charge time calculated?
- We divide the energy needed (14.85 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
