When it comes to using the Samsung Galaxy Note 9, of course, you already know that you’re using one of the best phones on the planet.

It makes use of the latest specs with its Snapdragon 845 processor, a whopping 8GB of RAM, a large Super AMOLED display, and some great cameras.

Also, finally, Note 9 has an upgraded battery of 4,000mAh, a lot better than the previous Note 8’s 3,300mAh battery that would burn out rather quickly.

With that said, just because the Note 9 has a larger battery doesn’t exactly mean things are a complete 180° change. You can still burn through the battery capacity of the phone rather quickly, simply because Note 9 is an absolute powerhouse.

The Power of Portable Charging

Of course, you can use a power bank with the phone while you’re out and about. However, if you don’t want to use a completely separate power source, then a battery case is the next best option.

Using a battery case with your Note 9 can be a great experience because if you’re running out of power, then you can simply press a button and the case will charge it.

In this guide, we’re going to be covering the battery cases for Note 9. Just something to know is that we’re only mentioning a few because the brands that do sell battery cases for the smartphone aren’t exactly well-known.

So we’re recommending brands that are well-known and trustworthy to purchase from.

Battery Cases in this Guide:

Mophie Juice Pack for Samsung Galaxy Note 9

Mophie is a leading brand when it comes to battery cases and for good reasons, too. As their cases are high quality, by being made of great materials and they’re designed well.

This Juice Pack of theirs for the Note is has a rather low power capacity when it comes to battery cases, that said, it’s what we expect from Mophie in the first place.

Just Enough Power

The Mophie case has a 2,525mAh power capacity and even though this is quite a bit lower than another case for Note 9, the design of the case is pretty good because of it. With the power capacity, you’re able to at least charge the Note 9 halfway. You’re not going to be getting a full recharge.

The form factor of the case is slim though and this is something that a lot of people worry about when it comes to battery cases. As they’re a lot larger than just your regular case.

Has a Somewhat Slim Form Factor

With the case having a length of 6.8 inches, a width of 3.2 inches, and a thickness of 0.7 inches. The design of the case is pretty good with it having a slim top at the back, so the entire case isn’t thick.

It’s also easy to use with the power button and four White LED power capacity indicators being at the back.

Access to the Samsung Pen is easy as there’s a small hatch in the corner to get the pen from, even with the case on.
