5 Best Galaxy S9 Battery Cases is a post by Cory Gunther from Gotta Be Mobile.

These are the best battery cases for the Galaxy S9. Cases that will keep your phone safe and give you extra battery life at the same time. Samsung’s phones offer pretty excellent battery life, but it can always be better. Here’s why you should want a battery case and some of the best ones available.

With a big 5.8 or 6.2-inch curved display and glass covering the front and the back, a case is highly recommended. If you use a case, you might as well get extra features at the same time.

There are a few different battery cases to choose from. Most of them offer wireless charging too, so you’re not losing any features either. There are a few quality cases from brands we know and trust. Or, you can get some cheap no-name brands that might not last as long as advertised. We’ve found some priced around $30 although you’ll need to spend a little more to get a battery case from a reputable brand.

Before we begin, it’s worth mentioning the size of the Galaxy S9 and S9+ internal battery. That way you can compare battery cases and extend battery life as much as possible. You get 3,000 mAh in the S9, and a 3,500 mAh battery in the S9+. However, they’re no longer removable. As a result, the best thing for users is a portable battery charger or a battery case.

These cases can make your S9 last for 2-3 days on a single charge. Perfect for business users, road warriors, or when you go on vacation. Even if you don’t use it daily, a battery case is a good accessory to have when you need it. These are basically durable and rugged cases with a battery pack built-in. Giving you juice and protection at the same time. Some even have a detachable battery so you can snap it on when you need it, and keep your phone thin and easy to carry when you don’t.

Another reason people get battery cases is after they’ve owned a phone for a year or so. Over time, your battery will start to degrade a little bit, and eventually, it won’t last as long as it did when you first bought it. And while the Galaxy S9 is still relatively new, it’s never too early to get a battery case. These are a few of the best ones available now, and we’ll add to this list as more battery cases get released.

Zero Lemon 5,200 mAh S9+ Case ($40)

The first battery case on our list comes from Zero Lemon. For years they've offered excellent battery cases, and this year they have two great options for the Galaxy S9 and S9+. 

However, we're recommending the Galaxy S9+ battery case because it's bigger and because we're expecting the S9+ to be the more popular device. Just know that they have one for either phone you decide to buy. 

ZeroLemon's battery case adds 5,200 mAh to the already decent 3,500 mAh battery. Giving you a total of 8,700 mAh of juice. That's more than enough to last 2-3 days, if not longer. The company uses a soft-touch matte finish to the TPU and polycarbonate shell, and there's an LED light so you know when the case is charging your phone. As an added benefit, it supports USB pass-thru technology. Meaning you don't have to take the case off to add or transfer files on your Galaxy S9 over USB. It's only $40 and will be available near the end of March. 

Buy it from Zero Lemon for $39.99
