The Best iPhone 12 Battery Cases For Backup Power

A Buying Guide for the Ultimate iPhone 12 Battery Cases

If you’ve decided on purchasing a battery case for your iPhone but aren’t sure of the technical aspects just yet, this guide will help you out. We’ll discuss the various considerations you should look into before buying a battery case for your iPhone 12. We’ll also cover all the features useful for boosting performance and making a product much more worthwhile.

What Is A Phone Battery Case?

A phone battery case is basically a power bank and a phone case combined into one. Rather than simply using a power bank that has a high chance of getting lost, a battery case avoids this problem by keeping your phone and the battery together at all times. Additionally, an iPhone battery case also allows users to ditch any cables required with traditional battery packs — the sort of accessories that tend to get lost. Battery cases don’t require cables for charging, some even include wireless technologies, allowing the case to be recharged without a cable. While a battery case is typically used as a case with a phone inside, it can also be removed and used as a power bank. The only difference is that instead of two items, a power bank and a cable, you’ll only have to carry a battery case, which is much less likely to get lost or left behind.

Things To Look for in an iPhone 12 Battery Case

There are multiple things you should consider before buying a battery case for your iPhone, we’ve lined up some of the most important factors to get your shopping experience a good head start.

Size

While this may seem like a pretty obvious factor, it’s crucial to consider before buying a case. The more power a battery case provides you, the thicker and bulkier it’s going to be. And, naturally, you’ll want to make sure the size of the case is well suited to the size of your hands. If you have larger hands, you can get away with buying something providing twice the average battery power. If you have smaller hands, though, a large frame will not only be extremely uncomfortable and hard to hold, but it might also increase the chances of your phone slipping out of your hands. Most of the time the size will also be proportional to the weight of the case, which is a useful thing to consider when selecting a device tailored to your needs.

Durability

Due to their bulky structures, battery cases can provide just as much, if not more, protection than heavy-duty iPhone cases. The raised edges provide complete 360-degree protection. That being said, it’s important to note that these battery cases typically aren’t waterproof, so it’s wise to take measures to keep your iPhone away from water. It’s also not a great idea to put these products in the same pocket as a water bottle while the battery case is on

Design

Unlike with a power bank, or a battery pack, that plugs into your iPhone as an external device, battery cases are fixed to the case and attached to your phone at all times. Think of it as a power bank combined with a regular silicone phone case. Since these cases include heavy-duty batteries inside, the shape of the case can get a bit distorted. Depending on the strength and power rating of the battery you choose, the shape of the case can go from relatively slim and compact to extra bulky and protective. Slender battery cases have the advantage of feeling lighter in your hands while not adding much weight to your bags or pockets. On the other hand, large battery cases provide a level of protection that slim cases usually don’t, even though they might be difficult to hold and carry for some people.

Must-Have Features for Your iPhone 12 Battery Case

Multiple Charging Options

Even though the majority of iPhone battery cases use Qi wireless charging technology nowadays, some cases still utilize a traditional cable-enabled charging method through a micro USB or lightning port. While this is fine, it can still get complicated when using wired headphones. This can also become an issue when you’re trying to connect your phone to a computer to transfer data, especially when you need to charge it at the same time. Having said all that, wired charging does tend to be a bit faster than the Qi-enabled wireless charging options. Since they both have their own pros and cons, you can still opt for a wired charging option. Wireless will add convenience since you’ll be able to charge the case and your phone together. You can do all this without needing to take your phone out of the case or go through the hassle of plugging in a cable when your phone is about to die. Having both choices available is the better option.

Compatibility

You’ll want to opt for a Qi-enabled battery case that can charge wirelessly over relatively short distances. Below the 40 mm mark is typically the way to go. Along with a Qi (chee) enabled battery case, you’ll also want to make sure your device is also Qi-enabled. All the models above the iPhone 8, including the iPhone 8 usually offer this feature.

Charging an iPhone 12 Battery Case

You can either get a battery case that charges wirelessly or use wires. For a non-wireless battery case, simply connect your iPhone 12 USB cable to the lightning connector on the case. You’ll want to make sure the other end is plugged into a power adapter, then plug the adapter into a socket. A yellow-orange light will indicate that the case is charging, this will turn green once the battery is full.
