Charging sharing between iPhones: myth or reality?
Before delving into the topic, it is important to clarify if it is really possible to charge an iPhone with another iPhone. The short answer is yes, it is possible thanks to a functionality called load sharing or "power sharing", although there are some limitations and details that you should know before trying it.
To explain in detail how it works, we will give you a brief summary of the technologies involved and how you can use them successfully.
Qi technology: the key to charging devices wirelessly
Qi (pronounced "chee") technology is a wireless charging protocol based on magnetic resonance wireless energy transfer. This protocol is widely used in mobile devices that support wireless charging, including iPhones.
- Qi allows devices to be charged without the use of cables, using energy transmitted by electromagnetic induction.
- Qi charging bases function as “power transmitters” and Qi wireless charging compatible devices as “power receivers.”
Load sharing: a functionality present in some iPhone models
Starting with iPhone 8, all iPhone models support Qi wireless charging. However, to be able to share charge with another iPhone, you will need to have an iPhone that has a bilateral wireless charger.
Below we'll describe how to use charge sharing with a compatible iPhone:
Preparation and requirements for load sharing
Before attempting load sharing, it is necessary to verify that both iPhones meet the following requirements:
- Both devices must have Bluetooth enabled.
- The iPhone that will share the load (the "transmitter") must have at least 50% battery.
- Both devices must support load sharing.
If you are sure that both devices meet these requirements, you can begin the load sharing process.
Steps to share load between two iPhones
Once you've verified compatibility and met the requirements, follow these steps to share charge between two iPhones:
1. Make sure both iPhones are turned on and unlocked.
2. Place the “transmitter” iPhone face down on a flat, stable surface.
3. Place the "receiver" iPhone on top of the "transmitter" so that both devices are aligned vertically, with their backs touching.
4. Wait for a notification to appear on the “receiving” iPhone warning that wireless charging has started.
5. Verify that charge is transferring correctly via the battery icon on the “receiving” iPhone.
Remember that the load sharing process can be slow, especially if both devices have low batteries. Please be patient and make sure the iPhones are aligned correctly to avoid charging issues.
Without a doubt, the charge sharing function between two iPhones is an interesting and useful alternative in situations where you do not have a charger or cable at hand. However, it is also important to take into account the aforementioned limitations and requirements in order to make the most of this technology and not waste energy unnecessarily.
