Even a year old, the Samsung Galaxy Note 8 is still a great device that can let you get more done — as long as you don't run out of battery life. If you've found your Note 8 battery can't make it through a full day of use anymore, you might want to consider a battery case that will offer you a bit of a boost on the go. We'd usually recommend the Mophie Juice Pack for most devices, but the best value is offered by the ZeroLemon SlimPower.

Most expensive

Mophie 2,950mAh Juice Pack Battery Case

Mophie is a trusted battery case maker and, as such, offers their products at a premium price. The Mophie Juice Pack offers modest battery capacity in a sleek design, backed by Mophie's quality customer service — always a good thing.

Modular battery case

Mophie Charge Force Case with Powerstation External Battery Pack

Another option from Mophie is the Charge Force Case, which features leather trim and an attractive, reinforced plastic body, but its secret can't be seen: it's magnetic. The battery pack charges the Note 8 through the same Qi wireless charging as a regular charging pad, and you're able to simply remove the battery pack from the back of your phone when you don't need it.

Massive capacity

ZeroLemon 10,000mAh Ultra Power Battery Case

If you don't mind carrying around a brick in your pocket and never want to see another low battery warning again, you'll want to snag the ZeroLemon Ultra Power Battery Case. With a 10,000mAh battery, this thing will keep your phone juiced up even through the busiest travel days. It's also designed to be rugged against drops and features a rubberized material finish for a nice comfortable grip in hand.

Slim it down

ZeroLemon 5,500mAh SlimPower Battery Case

Sold on getting a ZeroLemon case but wish they offered something a little less bulky? You should get the ZeroLemon SlimPower case, a more pocket-friendly design that offers half the battery capacity — but at half the price, too — for those who value good design over pure battery power.

Goldilocks battery case

RUNSY 6500mAh Battery Case

Positioned between the two ZeroLemon cases with a 6,500mAh battery, RUNSY somehow features a slimmer design than even the SlimPower ZeroLemon case. It's also a very well-reviewed case on Amazon, which is nice to see from a manufacturer that we're not too familiar with.

Best Value

PowerBear 4500mAh Battery Case

Finally, we'll recommend the PowerBear battery case for the Note 8. It features a 4,500mAh battery and a rather sleek design for a battery case. This case is backed by a two-year warranty and also comes with a screen protector, which is a nice bonus.

It's worth keeping in mind that battery cases are sort of notorious for issues. Fortunately, the brands on our list offer good customer service so if you have any issues with the performance or durability, don't hesitate to reach out. The Mophie Charging Station is a good option for those who would prefer not to have a massive battery bump on the back of their phone 24/7, but the ZeroLemon SlimPower offers the best overall value.
