The 12W charger and all of the Apple USB-C chargers deliver nearly identical performance, charging the phone to 85 percent in about an hour and 20 minutes. With the included 5W adapter, the phone takes almost 3.5 hours to fully charge. The iPhone 7 Plus, which has no official support for USB-C fast charging, delivers some interesting results. Let’s take a closer look at how each phone performs when charged up with each of these five power adapters. That sound you hear is your wallet crying. Apple sells those for a whopping $19 for a 1-meter cable, or $35 for a 2-meter cable. But no matter what USB-C power adapter you use, you’re going to need a USB-C Lightning cable. Here’s one for $25 (we haven’t tested it). Any USB-C adapter that supports USB Power Delivery should work just fine. You can, of course, buy less expensive USB-C adapters than Apple’s. We then charged them up with each of our five test adapters, making note of the charge level every five minutes.

That’s less than 8 percent larger, but it is enough of a difference that, even if the iPhone 7 Plus were to draw just as much power as the other phones, it would take just a little bit longer to charge up.įor each of these phones, we drained them to 1 percent remaining battery life, then made sure no apps were running and the phone was in airplane mode to prevent any background activity like app updates or photo syncing. The iPhone 7 Plus has a slightly larger batter at 2900 mAh.
The former is 2691 mAh and the latter 2716 mAh-that’s about a 1 percent difference, so we’ll just call those 2700 mAh. The iPhone 8 Plus and X have essentially the same size battery. Wondering how the newer iPhone XR and XS perform? Our cursory follow-up tests show no significant difference in charging rates between them and the iPhone X, with the exception of larger batteries in the XR and XS Max taking a little bit longer (as expected). We tested three phones: iPhone X, iPhone 8 Plus, and iPhone 7 Plus. What’s more, we wanted to see how these new phones stack up against older iPhones that do not officially support USB-PD fast charging. It’s the same way the new MacBooks get charged over USB-C.īut we wanted to see how well that stands up to using the adapter that comes with your phone, and the 12W adapter that Apple includes with iPads. The iPhone X, 8, and 8 Plus all support fast charging from USB-C power adapters that support the new USB Power Delivery (USB-PD) specification. It’s a lot less expensive ($19) and nearly as fast.
The truth is, while USB-C fast charging certainly works, you’re much better off buying Apple’s 12W USB-A Power Adapter-the one that comes with most iPads. Is it even worth it? We grabbed five power adapters and three iPhones, ran a bunch of tests, and got to the bottom of the iPhone charging mystery. That’s two catches, and it’s starting to sound expensive. Oh, and a new USB-C to Lightning cable, too.
According to Apple, you can juice up your phone to 50 percent in just 30 minutes! There’s just one catch: You have to buy a new power adapter. New to this years’ iPhones is fast-charging capability.
We haven’t tested it yet, but it should charge your iPhone exactly as fast as all of Apple’s other USB-C power adapters. To use it with your iPhone, you still need to purchase a USB-C to Lightning cable.
