Yes, you can use a 15W charger for a 25W phone. However, it is important to note that using a lower wattage charger may result in slower charging speeds compared to using the recommended charger.

When it comes to charging a phone, the wattage of the charger plays a crucial role in determining the charging speed. The wattage refers to the amount of power that the charger can deliver to the device. A higher wattage charger can deliver more power, resulting in faster charging times.

In the case of using a 15W charger for a 25W phone, the phone will still charge, but at a slower rate. The phone will only draw as much power as it needs, so even if the charger is capable of delivering more power, it will not harm the phone. However, it is important to consider that using a lower wattage charger may extend the overall charging time.

It is worth mentioning that modern smartphones are equipped with advanced charging technologies such as USB Power Delivery (USB-PD) or Qualcomm Quick Charge. These technologies allow devices to negotiate and optimize charging speeds based on the capabilities of both the charger and the device. So, even if you use a lower wattage charger, your phone may still charge at an optimal speed based on these technologies.

However, it is always recommended to use the charger that comes with your device or a charger that is specifically designed for your phone’s wattage requirements. This ensures that you are using a charger that is compatible with your device and can provide optimal charging speeds.

Using chargers with higher wattages than what your phone requires is generally safe as long as they are from reputable manufacturers and comply with safety standards. However, using chargers with significantly lower wattages may not provide sufficient power for your device and may result in slower charging speeds.

In conclusion, while you can use a 15W charger for a 25W phone, it is advisable to use the charger that comes with your device or a charger that is specifically designed for your phone’s wattage requirements to ensure optimal charging speeds.
