The iPhone 7 and 7 Plus came out to mixed reviews. Most early users love the new cameras, water resistance, and speed. The decision to drop the 3.5 mm headphone jack, on the other hand, has rubbed some people the wrong way.
One aspect of the new iPhones that we haven’t seen anyone talking about, however, is the in-box charger. That white cube shipped with the iPhone 7 and 7 Plus is more or less the same one that Apple has included with every phone since the iPhone 5. And if that’s what you’re using to charge your new iPhone 7, you’re getting shortchanged.
How come? That cube charger can only provide 5W (5V, 1A), and just like the iPhone 6 Plus and 6S Plus, the iPhone 7 and iPhone 7 Plus is capable of pulling more current, and thus charging faster.
For those of you who aren’t engineers, here’s the simple explanation: When we charge a device, the phone or tablet “tells” the charger how much power it wants. It can’t, however, pull more than the maximum that the charger is rated for, which limits the amount of power delivered to the device.
The iPhone 6 and 6S, for example, pull more than 1A, but not much more. When tested with a 2.4 amp charger, there wasn’t much difference in charge times. The iPhone 5 was limited to 1A charging, so the white cube was all anyone needed.
In our testing of the iPhone 7 and 7 Plus, however, both phones drew more than 1A when plugged into the 2.4A port in our Wallport r430 and Wallport r1240, reaching a full charge after about 2 hours. That shaved about 30 minutes off the iPhone 7’s charge time and about 90 minutes from the 7 Plus’s charge time compared to the in-box charger. This 7 Plus saved so much more time because it has a bigger battery – 2,990 mAh compared to 1,960 mAh on the iPhone 7.
Phones and tablets tend to pull more power when the battery is at its lowest point, and as the battery fills, the device gradually requests less power. An iPhone 7 or iPhone 7 Plus at 5 percent charge can request about 1.9A – much more than the 1A in-box charger would allow.
As you can see, both phones fill rapidly in the early stages of charging, but the rate slows down over time:
Using the 2.4A port of a Wallport r430, the iPhone 7’s 1,960 mAh battery reached 48 percent capacity in 30 minutes, and was fully charged after 1 hour, 52 minutes. With the white cube, the phone was only 30 percent charged at 30 minutes, and only hit 100 percent after 2 hours. 30 minutes.
The 7 Plus, on the other hand, reached 40 percent charge within the first half hour of charging on the 2.4A port in the Wallport r1240. In that same period of time, the in-box charger only got the 7 Plus to 23 percent. Using the in-box charger, 7 Plus owners would have to wait 3 hours, 30 minutes to reach 100 percent.
Keep in mind that these charge times might be faster than what you get in the real world. We charged the phones in airplane mode to minimize any differences that might occur if, for example, the screen turned on because of a notification. The only times the screens were turned on was when we checked the battery percentage.
Even if you aren’t actively using your phone, it might have active radios scanning for Wi-Fi that drain power while charging. If you are charging while posting to social media or watching videos, you might charge at a slower rate. That’s part of the reason why you’ll want a 2.4 amp charger that gives the phone the maximum current it can pull and ensures the fastest charge.
So if you’re a new iPhone 7 or 7 Plus owner, or thinking of becoming one, consider grabbing a Ventev 2.4A charger to power up at the fastest rate. After that, you’ll just need to figure out what to do with your extra time.
