And both the iPhone 12 and the MagSafe Battery Pack have built-in safety features (Opens in a new window) that help prevent the products from overheating and minimize battery degradation, but limit charging capability and speed in the process. MagSafe is more efficient than Qi because the magnets ensure perfect positioning of the phone on the charger, but there is still a significant amount of lost power. If you use a regular Qi wireless charger to charge a phone, about half the power is lost due to device placement, heat, and other environmental factors. To make things even more confusing, the effective mAh capacity doesn’t account for inefficiency. The Apple MagSafe Battery Pack charges your iPhone 12 at up to 5W when unplugged, and at up to 15W when plugged in. (A lot of math is involved in figuring this out Apple Insider’s Wesley Hillard (Opens in a new window) does an excellent job of breaking it down.) If their voltages are different, the effective mAh rating changes. Since all the iPhone 12 models have 3.81V batteries and the MagSafe Battery Pack has a 7.6V potential, the Battery Pack’s effective mAh capacity is actually 2,920mAh. Milliamp-hours (mAh) theoretically define a battery’s capacity to power a device-or recharge a device, in the case of battery packs-but that statistic is calculated with the assumption that the two devices have the same voltage. But the numbers are once again deceiving. The MagSafe Battery Pack’s 1,460mAh capacity might seem low at first glance it’s little more than half the capacity of the iPhone 12 mini’s 2,227mAh battery, and far less than the 5,000mAh external batteries you can find for a quarter of the price. The white MagSafe Battery Pack doesn't match the aesthetic of the iPhone 12. For instance, you may read the news on your morning commute, check your messages a few times during the day at work, and then turn on Spotify and scroll through Twitter on the way home. That will have a different effect on battery than our torture tests. Most people use their phones on and off throughout the day.
We start with a full charge and force the phone to do battery-intensive tasks nonstop until it's drained. The truth is that most battery drain tests, including our own, aren't an accurate representation of day-to-day usage for any phone.
Thanks to Apple's more efficient hardware and software, our tests showed the iPhone 12 Pro Max's battery lasting for more than 15 hours, compared with a bit over 11 hours for the Galaxy S21 Ultra.Īnd even those tests don't tell the whole story. It would also be useful to have a USB-C port in addition to the Lightning port.Īt 3,687mAh, the iPhone 12 Pro Max’s battery may seem paltry compared with the 5,000mAh cell in the Samsung Galaxy S21 Ultra, but don't be fooled by a simple number. We wish Apple offered designs that complemented the iPhone 12, as a thick white puck stuck to the pack of the back of a blue or green iPhone 12 looks clunky. If the device stops working and there’s no obvious damage, you can take it to any Apple Store for repair or replacement.

A Lightning port and an indicator light are on the bottom edge. The charging face of the battery pack is covered in gray silicone that matches the logo on the other side. The outer shell is made of a durable white plastic with a gray Apple logo centered in the upper half. The aesthetic here can be best described as utilitarian.
It works with every MagSafe-compatible iPhone and fits perfectly on the back of the iPhone 12 mini. The MagSafe Battery Pack is a small, slightly chunky device that measures 3.75 by 2.5 by 0.43 inches (HWD). Apple’s external battery solution may seem pricey when compared with other portable chargers and power banks, but its excellent build quality and one-year warranty make it one of the best ways to charge your iPhone on the go, and our Editors’ Choice winner for iPhone 12–compatible external batteries. If you make heavy use of your iPhone 12 and often find the battery running low while you're out and about, the Apple MagSafe Battery Pack ($99) will likely become your favorite new accessory. Small enough to slide into a pocket or bag, the MagSafe Battery Pack adds hours of use to your phone, snapping neatly into place with the aid of precisely positioned magnets.
