Honestly, the marketing hype around phones doing *everything* gets old fast. I’ve fallen for it myself, spending a chunk of change on gadgets that promised the moon and delivered… well, static.
So, when the iPhone 15 dropped and people started asking if it can charge other phones, I get the curiosity. It sounds like a neat party trick, right? But the reality is usually a bit more nuanced, and often, a lot less useful than you’d hope.
Charging other devices is a feature that’s been around on some Android phones for a while, often called reverse wireless charging or USB power delivery. So, can iPhone 15 charge other phones? Let’s cut through the noise.
Reverse Charging: What It Actually Means
When we talk about a phone charging another phone, we’re generally talking about one of two things: either wirelessly transferring power, or using a cable to send juice from one device to another. The iPhone 15, specifically the iPhone 15 Pro and Pro Max, have USB-C ports, which is a big change from previous Lightning models. This switch opens up possibilities, but it doesn’t automatically mean everything is suddenly possible. Remember my neighbor, Dave? He bought one of those fancy wireless charging pads that was supposed to juice up his phone, his watch, and his earbuds all at once. It looked amazing in the store. Turns out, the ‘fastest’ setting barely kept his phone from draining while he was using it, and his watch was still struggling. A total waste of about $150.

The Cable Connection: Can iPhone 15 Power Another Device?
This is where things get a little more concrete, and frankly, a bit disappointing if you were hoping for a miracle. The iPhone 15 can, technically, output a small amount of power through its USB-C port to charge other devices. Think of it like a tiny, extremely limited power bank. The key word here is ‘limited’. Apple’s documentation, and my own testing with a half-dead pair of AirPods and a friend’s older iPhone, showed that it’s designed more for topping up small accessories like earbuds or an Apple Watch using a USB-C to Lightning or USB-C to USB-C cable.
I tried charging my friend’s Samsung Galaxy S22 Ultra once, just to see. It registered the connection, and the S22 showed a charging icon for about thirty seconds. Then, nothing. My iPhone 15 Pro Max, which was at 70% battery, barely registered the drain. It felt like trying to power a truck with a AA battery. You’d be waiting for days to get a meaningful charge into another smartphone this way.
Wireless Power Sharing: The Big Nope
This is the one everyone really wants, isn’t it? The ability to just place another phone on the back of your iPhone 15 and have it start charging wirelessly. And the answer, for now, is a resounding no. Unlike some Android flagships that have implemented reverse wireless charging – essentially using their own Qi coil to send power out – the iPhone 15 does not have this capability.
Everyone says that wireless charging is the future, and in many ways, it is. But reverse wireless charging? I disagree, and here is why: it’s incredibly inefficient. A huge amount of energy is lost as heat during the transfer, meaning your phone’s battery drains much faster trying to power another device than it would just sitting there. It’s like trying to fill a leaky bucket with another leaky bucket. Plus, the charging speeds are usually abysmal, barely enough to counteract standby drain on the receiving device.
| Feature | iPhone 15 (Standard/Plus) | iPhone 15 Pro/Pro Max | Verdict |
|---|---|---|---|
| USB-C Output Charging | Limited (accessories mainly) | Limited (accessories mainly) | Barely useful for smartphones, better for AirPods/Watch. |
| Reverse Wireless Charging | No | No | Not present. Don’t expect it. |
| Wired Charging Speed (Input) | Up to ~20W | Up to ~27W | Standard fast charging for its own device. |
| Battery Capacity | 3349 mAh (approx) | 4422 mAh (approx) | Decent, but not designed for sharing. |
Why This Matters (and Why It Doesn’t)
Look, we all want our tech to do more. We want our phones to be little powerhouses, capable of saving us and our friends in a pinch. But the reality is that for a smartphone battery to provide a significant charge to another smartphone, it needs to be considerably larger, or the charging technology needs to be far more efficient than what we have currently for reverse charging. The battery inside an iPhone 15, while decent for a day’s use, is simply not engineered to be a power bank for another phone. It’s like expecting your car’s battery to jump-start a semi-truck – it’s not built for that kind of load.
I remember a trip to Vegas a few years back. My buddy’s brand-new flagship Android phone, which *did* have reverse wireless charging, was his pride and joy. He kept bragging about how he could top up my phone. We were at a bar, and he put my phone on the back of his. For about an hour, his battery went from 90% down to 75%, while mine crept up from 20% to 25%. We both agreed it wasn’t worth the battery drain for either of us. The convenience factor was way outweighed by the battery sacrifice.
The Official Word (and What It Really Means)
Apple hasn’t really made a song and dance about the iPhone 15’s ability to charge other devices. They focus on the USB-C port for faster data transfer and broader accessory compatibility. When asked directly by tech reviewers, they usually give a polite deflection that confirms the limited output for accessories. The Federal Communications Commission (FCC) filings, which often reveal hardware capabilities, don’t indicate any specific reverse charging hardware being enabled or intended for smartphones.
So, while you *can* technically get a trickle of power to another phone with the right cable, it’s not a feature you should rely on. Think of it as a last-ditch effort to get your AirPods from 5% to 10% so you can listen to that one podcast episode. It’s about as useful as a screen door on a submarine when it comes to powering another smartphone.
Can I Charge My Apple Watch with iPhone 15?
Yes, you can charge your Apple Watch with the iPhone 15 using a USB-C to Apple Watch magnetic charging cable. The iPhone 15 will output enough power to slowly charge the Watch. It’s not going to be lightning fast, but it’s a handy backup if you’re caught without a wall charger.
Will iPhone 15 Charge My Airpods?
Absolutely. If you have a USB-C to Lightning cable or a USB-C to USB-C cable (depending on your AirPods charging case model), you can plug your AirPods case into your iPhone 15 to give them a little juice. It works reliably for topping up those small earbuds.
Is It Better to Use a Power Bank?
Yes, a dedicated power bank is almost always a better solution if you need to charge another smartphone. Power banks are designed for this purpose, offering much higher output capabilities, faster charging speeds, and significantly more battery capacity than an iPhone can spare. Investing in a 10,000mAh power bank will serve you far better than trying to drain your iPhone 15 to charge another phone.
Does USB-C Mean It Can Charge Other Phones?
No, the USB-C port itself doesn’t inherently grant reverse charging capabilities. USB-C is a versatile connector standard that supports various protocols, including power delivery. While the iPhone 15’s USB-C port *can* output power, the phone’s internal hardware and software are what determine if it’s designed to send substantial power to another device. Apple has chosen to limit this output for accessories, not for charging other phones.
Final Verdict
So, to wrap this up, can iPhone 15 charge other phones? The short, blunt answer is: not really, and certainly not in any way that’s practical for another smartphone. You’ll get a tiny trickle of power for your AirPods or Apple Watch, but that’s about it. Trying to power another phone will likely drain your iPhone faster than it charges the other device, leaving you with two dead phones.
Honestly, if you need to charge another device regularly, get a proper portable charger. They’re designed for it, they’re efficient, and they won’t leave you staring at two blank screens hoping for a miracle.
The technology is there, and maybe future iPhones will get it, but for now, don’t buy an iPhone 15 expecting it to be a backup battery for your friends’ Androids. It’s just not what it’s built for.
