Introduction: The Feature Everyone Keeps Asking About
Our customer support team and product engineers love hearing from you guys. Recently, we've noticed a recurring theme in our inbox and community comments. It usually starts with a story like this:
"While I was on my way to work, my AirPods ran out of battery, leaving me to listen to the chaotic sounds of the morning rush hour. Next to me, I noticed someone quickly charging their earbuds using their Android phone, adding a bit of power before diving back into their music."
"So why can't I enjoy this feature on my iPhone?"
It's a fair question. If brands like Samsung, Honor, Google, and even Xiaomi offer "Reverse Wireless Charging" (sometimes called PowerShare on Samsung devices), why can't Apple?
The short answer? Your iPhone likely has the hardware to do it, but Apple won't let you use it.
The long answer? Apple has likely conducted thorough testing and found that reverse wireless charging generates too much heat and isn't efficient enough to be considered a standout feature, which is probably why they've opted not to provide software support for it.
But the good news is that all iPhones since the 15 series have USB-C ports, which enable reverse wired charging. This allows you to easily power your essentials, like AirPods and Apple Watch, using your phone and a USB-C cable.
What Exactly Is Reverse Wireless Charging?
In simple terms, it turns your smartphone into a wireless charging pad. Instead of just receiving power to charge its own battery, the phone transmits power from its battery to another device—like a friend's phone or a pair of earbuds—placed on its back.
It sounds like magic. Brands like Samsung have popularized this with "Wireless PowerShare," and Honor has been pushing boundaries with their reverse charging tech. The premise is solid: if your phone has 80% battery and your earbuds are dead, why not share that charge?

The "Secret" Hardware Inside Your iPhone
Here is where it gets interesting. Did you know that teardowns and FCC filings for iPhones as far back as the iPhone 12 series hinted at hardware capable of transmitting power, not just receiving it?
Technically, the iPhone does use a form of reverse wireless charging right now, but only in one very specific, Apple-controlled scenario: the discontinued MagSafe Battery Pack.
When you plug your iPhone into a Lightning or USB-C cable, it can wirelessly send power to the battery pack on the back.
So, the copper coils are there. The capability exists. Why is the switch turned off for everything else?
Real Stories: Why It's Not as Magical as It Seems
We dug into feedback from tech enthusiasts and mixed-ecosystem users (people who use both Android and iOS) to understand the reality of reverse wireless charging. It turns out, the dream of "infinite power sharing" often clashes with physics.
Case Study 1: The "Hot Potato" Issue
One of our community members recently switched from a Pixel to an iPhone. He told us that while he missed the idea of reverse charging, he didn't miss the heat. "I tried to charge my watch on the back of my phone while at a coffee shop. Within 10 minutes, both devices were incredibly hot, and my phone throttled so much that I couldn't even scroll Instagram smoothly. Plus, I lost 15% phone battery to give my watch maybe 3%."
Case Study 2: The Alignment Nightmare Another user shared a frustration that echoes
what we see in many tech forums. "Without magnets, it is a nightmare. I put my earbuds on the back of my husband's Galaxy. Someone bumped the table, the buds slid two millimeters to the side, and charging stopped. We didn't realize it until we left. Result? Dead earbuds and a frustrated husband."
These aren't isolated incidents. Wireless charging is already inefficient, as energy is lost as heat. When you do it in reverse, you are converting chemical energy (battery) to electrical, then to magnetic (wireless), and back to chemical. The energy loss is massive—often up to 40-50%.
Why Apple is Waiting Before Introducing Reverse Wireless Charging
As a company that lives and breathes charging tech, we suspect Apple is holding back for three main reasons:
-
Thermal Management: Heat is the enemy of battery health. Apple is notoriously protective of iPhone battery longevity. Enabling a feature that generates excess heat for inefficient charging contradicts their goal of keeping your phone usable for 3-4 years.
-
Charging Speed: Most reverse wireless charging tops out at 4.5W or 5W. It is excruciatingly slow. Apple prefers not to release a feature if the user experience feels "broken" or sluggish.
-
The Qi2 Standard: With the adoption of Qi2 (which is essentially open-standard MagSafe), the industry is moving toward magnetic alignment. Until reverse charging can be magnetically secured and efficient, it remains a gimmick for many.
The Better Solution: Don't Drain Your Source
Let's be honest: draining your iPhone battery to revive your accessories is a desperate move. It's like siphoning gas from your car to power a lawnmower while you're stranded on the highway.
The real fix isn't reverse charging; it's ensuring you never leave the house with a low battery on any device. The shift in 2024 and 2025 is toward dedicated, high-speed charging stations that handle your entire ecosystem at once.
If you are tired of the "dead AirPods" scenario, the solution is a habit change powered by better gear.
Recommendation: The Powerhouse for Your Desk
Instead of hoping your iPhone can trickle-charge your watch at 5W, we recommend the ESR Qi2.2 25W 3-in-1 Wireless Charging Station.
-
Why it wins: It supports the new Qi2.2 standard, delivering true 25W wireless fast charging to your iPhone.
-

What About On the Go?
If you need power while on the go, a dedicated MagSafe power bank is infinitely more efficient than reverse charging. It doesn't overheat your phone's internal battery, and it attaches magnetically.
The Verdict
Will iPhones ever get full reverse wireless charging? Maybe. But until the technology can overcome the heat and efficiency loss, it's not a feature you should base your purchase on.
At ESR, we focus on what works now. Fast, safe, and efficient charging that protects your devices rather than putting them at risk.
