If you lot've bought an iPhone 12 or iPhone 12 Pro already, or are perhaps considering picking one upwardly down the line, you'll probable want to invest in a ameliorate charging solution than that old 5-watt adapter you might accept lying around from Apple-branded handsets of the past.

We've tested the iPhone 12'south charging speed on that iconic brick, besides every bit Apple tree's new 20W USB-C and MagSafe chargers, and the results are center opening.

iPhone 12 charging options explained

Get-go, a bit of an explainer. No iPhone 12 model comes with chargers of any sort, though you lot exercise get a USB-C-to-Lightning cable in the box for your troubles. Interestingly, this cable tin't exist used with the cube-shaped USB-A charging adapters of old; y'all'll need Apple's new USB-C brick to make apply of the cable and, thus, faster speeds.

That new charger costs $19, and is rated at 20 watts. Only there's yet another charging selection for the iPhone 12 — Apple's MagSafe wireless charger, which takes the form of a puck that magnetically attaches to the back of the phone and sends 15 watts of juice. The MagSafe charger costs $39, but y'all'll still need to buy a 20W brick to use information technology. In the end, the whole wireless setup will end upwardly costing yous only shy of $lx.

iPhone 12 charging speeds: 20W vs. MagSafe vs. 5W

So, how practise they all perform? Let's start with the 20W option, equally that's what Apple recommends if yous're afterwards the optimal high-speed charging experience for your new iPhone. Information technology also replaces the 18W brick that came with last year's iPhone eleven Pro models, that used to toll $29 separately — making information technology a slight improvement in power delivery, for less money.

Apple quotes roughly a l% charge afterwards a xxx minutes when using this USB-C adapter. In our experience, that seems a bit conservative. We actually saw 57% in that span of time on our iPhone 12, which isn't too shabby at all. Sure, information technology's not the 93% of the OnePlus 8T and its 65W Warp Charge system, but it'south likely speedy plenty for most folks.

We suppose if you connect the 20W charger to an iPhone 12 mini, you'll come across an even faster event than this, equally that five.4-inch variant is all simply certain to pack a smaller battery — while the iPhone 12 Pro Max may land closer to Cupertino'due south official l% estimate.

The next fastest selection, as you might expect, is the MagSafe system. Using the wireless charger, we saw 32% from empty later on a one-half hr. That's inappreciably quick in the grand scheme of things, though information technology isn't too bad for wireless charging. Wireless systems typically involve lower wattages and are less efficient in full general, because they lose more potential energy as heat.

In the end, whether you opt for the 20W USB-C or MagSafe setup, y'all're either going to see a noticeable increment in charging speed or convenience over the classic 5W brick. Nosotros dug up one such adapter and a USB-A-to-Lightning cable, and timed the result. Pitifully, after 30 minutes, our iPhone 12 was sitting at only 21%.

Of grade, that isn't great, merely it is what nearly people likely have lying effectually. Once you factor in charging, the iPhone 12 mini and iPhone 12 in particular aren't quite every bit attractively priced every bit they may initially seem. You'll spend anywhere from $20 to $60 to go a faster charging feel for your new iPhone, on height of the cost of the device itself — whereas nigh Android flagships come with everything required for fast charging correct in the box.

Personally, if it were my money, I'd merely swing for the 20W adapter for $19, and only be done with information technology. MagSafe is neat, but it's not revolutionary or all that easier to use in practice than a skillful onetime-fashioned Lightning cable. To me, MagSafe'southward value is less in charging and more than in what it could add to accessories similar cases, mounts, camera lenses and the like. Besides, the fact that Apple withal at least includes a USB-C cablevision in box arguably gets you almost halfway to a fast-charging solution for your new iPhone, which I suppose is a glass-half-full way to look at things.
