Samsung’s Galaxy S24 series has been renowned for its revolutionary design, sophisticated AI features, strong performance, and brilliant display. Where most users are disappointed, though, is charging speed. Fast charging, in 2025, has become an essential feature of flagship phones. While most Chinese brands are providing 100W+ charging speeds, the Galaxy S24 still only tops at 45W wired charging and 15W wireless charging.
For a phone that’s marketed as a premium smartphone, these figures are disappointing. People expect the very best of everything at this price, but Samsung is being conservative in terms of battery and charging tech. Let’s look at why Galaxy S24’s slower charging is annoying customers , some Galaxy S24 charging tips and how it stacks up against competition, and if Samsung’s conservative approach is actually justified.
The Charging Specs of Galaxy S24
1. Wired Charging – Up to 45W
If you have a Samsung official Super Fast Charger, the Galaxy S24 Ultra supports wired charging speeds of up to 45W, which can fill the battery to roughly 50% in 30 minutes. This is not the case for the base S24, which has a maximum charging speed of only 25W, and will take somewhat longer to charge the battery than the S24 Ultra.
2. Wireless Charging – Up to 15W
Samsung also includes 15W wireless charging via Qi that enables you to charge without a wired connection. While charging wirelessly is convenient, it will be slower than wired charging. Nonetheless, it’s adequate for someone who will be charging the phone overnight or only needs a slow charge throughout the day.
3. Reverse Wireless Charging – (Wireless PowerShare) – Up to 4.5W
One of Samsung’s highly appreciated features for their phones is Wireless PowerShare. Wireless PowerShare allows you to charge other accessories such as your Galaxy Watch, Galaxy Buds, or even another phone by simply placing it on the backside of the S24. Although Wireless PowerShare is limited to charging other devices at a max charging speed of 4.5W, it will still suffice for all emergency charging needs.
4. Battery Capacity
- Galaxy S24: ~4,000 mAh
- Galaxy S24+: ~4,900 mAh
- Galaxy S24 Ultra: ~5,000 mAh
Samsung has optimized these batteries with AI-driven power management, helping extend usage times despite moderate charging speeds.
5. Charging Time
The Galaxy S24 Ultra takes just about an hour to fully charge via the provided 45W charger, the base version, however, may take 75 to 80 minutes with the 25W charger. This is satisfactory, it is a good step behind competitors, some of whom can achieve a full charge in less than 30 minutes.
Why Slower Charging Frustrates Users
1. Competitors Are Far Ahead
Such brands as Xiaomi, OnePlus and Realme are providing charging rates reaching 120W or even 150W that have an ability to charge a phone between 0 and 100 percent within less than 20 minutes. It is on this basis that the 45W appears sluggish by Samsung.
2. Premium Price, Mid-Tier Charging
Galaxy S24 customers who pay a premium price to purchase the products expect state of the art technology in all their departments. The slow charging experience is out of place with the rest of the futuristic specifications.
3. Lifestyle On-the-Go
Requires Rapid Charging.
The modern hectic society is renowned with a significant number of users who prefer rapid top-ups as opposed to an overnight recharge. Even a 1520 minutes full charge can be considered a lifesaver, yet the Galaxy S24 is not able to provide such convenience.
4. The limitations of wireless charging
The 15W wireless charging is slow in comparison to the wired speeds, particularly at a time when Apple and other companies are trying to develop MagSafe-type enhancements.
5. Battery Health Concerns?
The rationale behind slower charging by Samsung is on the battery life and thermal control. Although this is a sound point, several users are being limited as far as other brands provide it with speed as well as safety.
Galaxy S24 vs Rivals
| Feature | Samsung Galaxy S24 Ultra | iPhone 15 Pro Max | OnePlus 12 | Xiaomi 14 Pro |
|---|---|---|---|---|
| Wired Charging Speed | 45W | 27W | 100W | 120W |
| Wireless Charging Speed | 15W | 15W MagSafe | 50W | 50W |
| Battery Capacity | 5000 mAh | ~4422 mAh | 5400 mAh | 4880 mAh |
| Full Charge Time | ~60 mins | ~90 mins | ~25 mins | ~20 mins |
| Reverse Charging | Yes (4.5W) | No | Yes | Yes |
Is Samsung Playing It Safe?
The limitation of charging speeds imposed by Samsung might be intentional:
- Battery Health: Reduced wattages put out reduced heat and maintain long term battery performance.
- Safety Issues: Rapid Charging Systems are more complexly cooled and more risky.
- Uniformity Between Models: Samsung does not divide its user experience by making it uniform.
Although these reasons hold some sense, convenience is what users tend to appreciate more than care at flagship prices.
Galaxy S24 Charging Tips & Battery Care
Although the Galaxy S24 cannot achieve the high charging speeds of certain rivals, it is possible to maximize charging performance and improve the battery life with a few clever considerations:
1. Use the Official 45W Charger
The Galaxy S24 can have a wired charge with a charge of up to 45W but only when using a compatible charger. Speed can be reduced by using third-party or lower-wattage chargers.
2. Allow fast charging in settings
Enter Settings/ Battery and Device Care/ Battery/ More Battery Settings and make sure that Fast Charging and Fast Wireless Charging are enabled.
3. Always Turn off Charging
When Gaming or Streaming.
Performance apps are heat-intensive and reduce the rate of charging. To achieve maximum performance, leave your phone undisturbed when charging.
4. Switch On Airplane or Power Saving Mode
These modes minimize background activity and assist your device to charge a bit higher.
5. Keep Your Phone Cool
The greatest of enemies is heat, both as far as charging speed and battery health is concerned. When charging your phone, do not leave it in direct sunlight.
6. Relax Overnight with Wireless Charging
Wireless charging can be slower (15W), but it is convenient, and is safe during nighttime.
7. Capitalize on Reverse Wireless Charging
Wireless Power Share (4.5W) should only be used in case of an emergency to ensure that you do not run out of charge on your main battery.

Conclusion
The Galaxy S24 series introduces innovation in most aspects, including display, camera, artificial intelligence, and productivity features such as the S Pen. But its performance on charging is a great disappointment to many users. With Samsung already having 45W wired charging, brands such as Xiaomi and Oneplus are now able to compete in terms of charging projections and capabilities up to 100W and more.
Samsung has a low risk attitude due to its focus on safety, battery, and long-term reliability. However, high-end consumers will frequently desire performance and convenience, and slowness of the charge spoils the otherwise sci-fi feeling.
Competitors might be better than the store is in terms of charging speed. However, in case you do care about durability, ecosystem, and the overall high-quality performance, the Galaxy S24 is not going to lose its strength, just do not expect to charge it within less than 20 minutes.
