Can I Charge a Phone from Another Phone?
Yes, you can charge a phone from another phone if the second phone supports reverse wireless charging. This innovative feature allows one modern smartphone to act as a wireless charging pad for another device. Here’s a detailed guide on how to charge a phone from another phone, along with some important considerations.
Understanding Reverse Wireless Charging
Reverse wireless charging enables certain modern smartphones to charge other devices using the phone's built-in wireless charging capabilities. This feature is supported by several models, making it a convenient and versatile solution for charging multiple devices.
Steps to Charge a Phone from Another Phone
To charge another phone using reverse wireless charging, follow these general steps:
1. Check Compatibility
Before you start, ensure that both phones support wireless charging and that the phone you want to charge supports reverse charging. This is crucial for a successful charge.
2. Enable Reverse Charging
On the phone that will provide power, enable the reverse charging feature. This setting is typically found in the settings menu, under battery or connectivity options.
3. Align the Devices
Place the phone that needs charging on the back of the phone providing power, ensuring that the charging coils are properly aligned. Accurate alignment is essential for the charging process to work efficiently.
4. Start Charging
Once the devices are aligned, the charging process should begin automatically. Keep an eye on the battery levels to ensure the charging is happening as expected.
Keep in mind that using reverse wireless charging tends to charge your device slower compared to using a traditional charger. Additionally, it may drain the battery of the charging phone more quickly.
Charging an iPhone with Different Cables
Yes, you can charge any iPhone 5 through iPhone 14 series with any lightning cable. Similarly, you can charge any iPhone 15 with any USB Type C cable, given that the charging cable matches the type. This flexibility is beneficial for those who have a variety of cables at hand.
Charging a Device with Another Battery
Charging a device with another battery requires careful consideration of the batteries' capacities and voltages. Here are some key points:
Charging with Different Capacities: To fully charge the device's battery, the charging battery must have a greater capacity than the battery being charged. If both batteries have the same nominal voltage, you will need a pump circuit to reach the required voltage for full charging.
Charging Batteries of the Same Voltage: You can share charge between batteries of the same nominal voltage by connecting them in parallel. This method is often sufficient to provide a temporary power boost and can help you in a pinch.
Heavy Discharge Care: If one battery is heavily discharged, be cautious about the initial heavy currents that may flow when connecting. This could potentially damage the equipment if not handled properly.
Apple’s Recommendations
Apple recommends the use of the Apple USB Power Adapter that came with your iPhone, or another compatible Apple power adapter. Using uncertified or counterfeit accessories may damage your iPhone and/or adversely affect its operation.
Remember, the use of official or certified accessories ensures both the safety and longevity of your device.
Conclusion: Reverse wireless charging is a handy feature for modern smartphones, allowing you to charge multiple devices from a single phone. While it may not be as fast as traditional charging methods, it provides a convenient solution for scenarios where immediate charging is needed.
