For extra hours of charge without the hassle of bringing the charging cable and power bank when you leave home, the best iPhone battery cases will give you additional screen time while still being lightweight. In addition to choosing a case that will work with your specific iPhone model, you’ll want to consider how much battery life you need versus how much bulk you’re willing to add to your phone. Also keep in mind handy features such as wireless charging and Lightning port access.
What to consider when shopping for iPhone battery cases
Because the battery is housed in the phone case, most battery cases are bulkier than regular cases. Often, the more powerful the battery, the heavier the case — so you’ll want to consider battery power, which is measured in milliampere hour (mAh) when shopping. If you mainly use your phone for texting and scrolling through social media, a battery case of up to 3,000mAh should provide one full charge. If you’re streaming a lot of videos, you may benefit from a battery with at least 5,000mAh. Similarly, if you're camping or otherwise off the grid without access to an outlet, a high-capacity 10,000mAh case should fully charge your phone about three times.
Additionally, some cases are compatible with wireless charging while others need to be plugged in via micro USB or a Lightning cable. Just keep in mind that cases with micro USB ports will not allow you to plug a Lightning cord into your phone without removing the case, and you’d need a micro USB to Lightning adapter to charge the case with a Lightning cord.
Of course, a good phone case will also protect your iPhone from damage. Each case below has raised edges to protect your phone from drops, and some even come with screen protectors.
Finally, not all the best iPhone battery cases below are compatible with every iPhone model, so be sure to check that it’ll fit your phone before clicking “add to cart.”
1. The fan favorite with a slim profile
Compatible phones: iPhone 7/8/SE (also available for iPhone X and iPhone 7 Plus/8 Plus) | mAh: 2,525 | Battery life: Up to 27 hours | Screen protector: No | Weight: 3.51 ounces
A popular pick with more than 2,000 five-star reviews, this iPhone case provides enough battery power for a moderate phone user at just over 2,500 mAh and protects your phone with raised edges and rubberized support pads on the interior. It’s compatible with wireless charging, but keep in mind that it uses a micro USB cord (included) for charging and syncing, and there’s no external Lightning port if you want to plug your phone in or use wired headphones.

A standby button lets you choose when to use battery power, and the case has LED indicators that let you keep an eye on the remaining battery life.
