The iPhone 12 Pro is still one of the best devices that you can pick up today, especially if you’re looking for one of the best-performing smartphones with an excellent camera setup, and a beautiful OLED display. The iPhone 12 Pro maybe two years old at this point, but it’s still capable of shooting some breathtaking photos; however, the battery may be due to a replacement. If you’re not quite ready to shell out more than $80 for a new battery, or you may have already replaced it, you might want to purchase a portable battery case to extend your device's battery life.

While battery cases are often considered bulky, heavy, and large, it’s worth considering for special occasions, as they can easily provide a full charge, or more, in a fairly slim and convenient form factor. We’ve also included the official MagSafe battery pack, which is supported on all MagSafe iPhones, including the iPhone 12 series, iPhone 13 series, and the latest iPhone 14 series.

Our recommendation

Battery cases are large, bulky, and add considerable weight to your device, but they can be handy, and some stand out with their unique approach. If you’re looking for the one that adds the least of the features mentioned above, then the Apple MagSafe Battery Pack is the one you should choose. Thanks to the built-in magnets, it can seamlessly attach to the back of your iPhone 12, 13, and 14-series, making it effortless and easy.

The ESR HaloLock power packs are also an excellent option if you’re looking for even more battery for your buck, and they work the exact same way, making charging straightforward.

Suppose you’re looking for a traditional charging case. In that case, the GIN FOXI, HUGUODONG, AFTRYOUGO, NEWDERY, and SNSOU cases are considered to be the best-rated ones on Amazon, and they appear to show the best lifetime and feedback from users. These are all very similar in terms of features, and most of them will continue supporting Apple Pay, but wireless charging will only work with the NEWDERY battery pack.

iPhone 12 Pro

It’s nearly identical to its larger iPhone 12 Pro Max sibling with its class-leading performance, and it too offers one of the best camera quality that you can buy in 2022.
