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 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.
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
The great catch about Elebase’s battery case is that it not only offers an understated and modest design that doesn’t add weight or heftiness to your phone, but also a modest price for high-quality protection. The 4,700mAh capacity adds tons of extra power to your phone, roughly doubling your battery life. It’s an affordable price too for the amount of quality packed into this case. The inside of the case is created with a microfiber lining to keep your phone’s case scratch-free — and the raised corners and 360-degree design of the bumper give you adequate protection against bumps and scratches too. The power button on the back turns on charging and changes color, alerting you of the battery life left in the case.
TRS 6,000mAh Battery Case
If you’re not hung up on many other details than having a case with a big battery, then TRS’s battery case is a good option. It flaunts a massive 6,000mAh capacity, which is twice the size of your Galaxy S9’s battery, making it ideal for those who spend long periods without access to a charger. It takes the same USB-C cable as your Galaxy S9, so you don’t have to worry about packing two chargers. You’ll always be aware of your battery life because the system features four lights on the back to show you how much power you have left in the case. You’re sure to love this, as it will ensure you’re not caught out by a flat battery. While it may not be the most aesthetically pleasing product and certainly augments your phone’s weight, we think these drawbacks are a small price to pay for never running out of battery no matter where you are.
i-Blades Modular Smartcase with Smartblade
Battery cases can be quite large, and all that extra power isn’t always necessary. If you don’t want to carry a bulky case constantly, 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 additional battery life. When it’s all been used, you can quickly detach it and attach another if your phone still needs to charge. There’s an additional option to employ the Smartblade’s SD card slot if you need more memory space. It also has an unexpected perk: the Smartcase also monitors the air quality around you. The case itself is slim, lightweight, and made of a durable polycarbonate shell with a soft-touch finish.
