The Samsung Galaxy S9‘s time in the sun may be over, but its time as your trustworthy pocket pal may not be. While it’s been supplanted as a flagship, Samsung’s high-powered 2018 smartphone is still a capable device. However, it’s usual that a battery can start to give out before the rest of a phone’s components, and that can really hamper your daily use. While a battery replacement is usually a good call, grabbing a battery case can solve some of your issues, give some good protection, and can provide an extra boost for really long days, even after a battery replacement.
While the number of available cases has dropped as the device has aged, there are still some worth buying. Here are some of the best Samsung Galaxy S9 battery cases you can still buy.
Mophie Juice Pack
Mophie is the undisputed king of the mountain wherever battery cases are concerned. While the Mophie Juice Packs don’t always have the largest capacity, their quality speaks for itself. The Mophie Juice Pack for the Galaxy S9 comes with 2,070mAh of extra battery power, and while that’s the lowest on this list by far, Mophie said it’s enough to power the phone for an extra 29 hours. It has priority charging too, so plugging in a charger will charge up the phone first and the case second. The case itself offers solid drop protection and cushioned corners. It’s lightweight and slim, and simply one of your best options. It’s available in April, and it will set you back $100.
Newdery 4,700mAh Wireless Charging Battery Case
Wireless charging is a big convenience if you need to top your phone up, but many battery cases don’t work with it. Thankfully, this battery case from Newdery is compatible with your wireless charger, so you can top up both your phone and battery case by dropping it on your charging pad. It works like many other battery cases — put it on, and click the button on the back to start charging your phone. The 4,700mAh battery more than doubles your phone’s battery capacity and should keep you going for a lot longer. It’s fairly bulky, but you have to accept some bulk with a charging case, and the TPU and polycarbonate build should help to keep your phone protected to boot.
Elebase Slim 4,700mAh Battery Case
Elebase’s battery case is a good option if you’re on a budget and want something with a sleek look that doesn’t add a big chin to the front of your phone. The 4,700mAh capacity adds plenty of extra power to your phone, roughly doubling your battery life. It comes at a low price tag but has surprisingly high quality — the inside of the case has a microfiber lining to keep your phone’s case scratch-free — and the raised corners and 360-degree design of the bumper provide decent protection against bumps and scratches as well. The power button on the back turns on charging and changes color depending on the battery life left in the case.
TRS 6,000mAh Battery Case
If you’re looking for a big battery and don’t much care about anything else, then TRS’s battery case is worth a look. It sports a massive 6,000mAh capacity, which is twice the size of your Galaxy S9’s battery, making it perfect for those long periods away from a charger. It takes the same USB-C cable as your Galaxy S9, so you can travel with just the one charger, and the system of four lights on the back shows you how much power you have left in the case, so you’re not caught out by a flat battery. Sure, it adds quite a lot of bulk to your large phone, but as an optional extra for when you need a boost, this is a great choice.
i-Blades Modular Smartcase with Smartblade
Battery cases can be quite large, and you don’t always need that extra power at every single moment. If you don’t want to carry a bulky case all the time, then check out the Smartcase with Smartblade from i-Blades. The extra battery power comes in the form of the Smartblade, which snaps onto the back of the Smartcase, providing up to 10 hours of extra battery power. When it’s spent, you can quickly detach it and attach another if you still more juice. What’s more is you can also expand your available memory with the Smartblade’s SD card slot. Strangely enough, the Smartcase also monitors air quality around you, and the case itself is slim, lightweight, and made of a durable polycarbonate shell with a soft-touch finish.
