For any smartphone owner, there is nothing more annoying than running out of charge at crucial moments.
But fortunately, a little-known charging trick can give iPhone users a few extra hours of power.
When two iPhone 15s are connected via a USB-C cable, the one with the lowest battery level will charge the other.
On X, iPhone user Sheel Mohnot posted a photo of him trying out the trick with the caption: “you can charge an iPhone from another iPhone.”
Someone responded “this is the future,” while another said “this is how you show someone you really love them.”
The little-known trick allows an iPhone 15 to donate charge to another iPhone. In the photo, the iPhone 15 Pro Max, launched last September. iPhone 15 models were the first iPhones equipped with USB-C charging ports
On X, iPhone user Sheel Mohnot posted a photo of him trying out the trick with the caption: “you can charge an iPhone from another iPhone.”
Once connected via a cable, the two iPhone 15 devices will automatically communicate to know which one has the lowest battery percentage.
The iPhone with the most battery charge will start powering the other one while losing charge, according to Apple reseller iStyle.
In The Apple community page.Some users noticed that the trick also worked when using an iPhone 15 to charge an older iPhone model.
One person said their iPhone 15 went from 98 to 89 percent charge to give the iPhone 11 a 10 to 32 percent boost.
However, an older iPhone model cannot charge an iPhone 15, but the other way around.
Additionally, the trick is not possible between two older devices, such as two iPhone 11s.
On X (Twitter), someone responded to iPhone user Sheel Mohnot’s post with the words “this is the future.”
Another said: “This is how you show someone you really love them.”
Since last year, the EU forced Apple to put USB-C charging ports on iPhones. A customer holds an iPhone 15 in a store in Los Angeles, California, on September 22, 2023, the day of the global launch.
Of course, if you want to charge an iPhone 15 with another iPhone 15, you will need a cable with USB-C connectors on both ends.
Meanwhile, if you want to charge an older iPhone with an iPhone 15, you’ll need a cable that has USB-C on one end and Lightning on the other.
In case you missed it, Apple started adding USB-C charging ports to its iPhones last year, starting with the iPhone 15.
Prior to this, Apple had used ‘Lightning’, the tech giant’s in-house charging design.
Apple was effectively forced to switch to USB-C by the European Union, which ruled in 2022 that having a single charging cable that can work with multiple devices made by different manufacturers will reduce electronic waste.

Apple, however, did not seem happy with the law, arguing that it would “restrict the industry’s ability to innovate.”
The same month the law was passed, Apple executive Greg Joswiak said the tech giant would comply, but only because it “would have to” and “had no other choice.”
“But we believe the approach would have been better for the environment and for our customers if the government was not so prescriptive,” he said.
