As with all Samsung Galaxy announcements there will be a slate of Galaxy S9 and S9 Plus battery cases available for the Galaxy S9 and S9+. Even though the GS9 and G9 Plus are fantastic smartphones, they will have slightly better battery life than the S8 and S8+. Meaning if you are someone that uses their phone a lot you will need extra charge or power as well as protection.
Below we share the list of the best Galaxy S9 and S9 Plus battery cases. If we are honest, you could pull together any list of Galaxy S9 and S9 Plus battery cases and you would see limited differences as they are very much copycats with variations on price, capacity or size/weight. But now there is a very different Galaxy S9 battery case alternative - the i-BLADES Smartcase. The i-BLADES Galaxy S9 series Smartcases are a completely new category of phone case that allow you to snap on and snap off battery power as well as storage and a multitude of other possible accessories.
So do you want more power, but happy to have more bulk? Or do you want snap-on battery life when you need it? Or more storage? Or even more features? Is it time to think differently with the phone case reimagined.
But check out the selection of the best Galaxy S9 and S9 Plus battery cases below and you can make your own decision.
Totally unique, offering much more than an average Galaxy Note 8 battery case, the i-BLADES Galaxy S9 or S9 Plus Smartcase.

2. ZeroLemon Galaxy S9 Plus Battery case 5200mAh
ZeroLemon are a consistent provider of Galaxy battery cases, the S9 is no exception. They are launching a Galaxy S9 Plus battery case with 5,200 mAh. A Permanent battery attached to your beautiful S9. Zerolemon claims that it will give 100% S9 battery life. Zerolemon have had good reviews in the past. So this is a solid choice if you want a standard Galaxy S9 battery case.

Mophie the "leader" in battery cases. The Mophie Juice Pack their Galaxy S9 battery case is the smallest capacity standard Galaxy S9 or S9 Plus battery case with the highest price tag. For this product the battery capacity has been radically reduced to just 2070 mAh down from 2700 in previous versions. Which if you have this permanently on your phone will drain faster than previous versions of Mophie cases and then you have the case on your phone while it charges.
You may also want to buy a screen protector because its "low profile" design leaves the screen exposed.
This is a rechargeable portable battery pack 5,200 mAh. Made of TPU. It packs a punch for a Galaxy S9 battery case. But I would beware of the build quality as it is clearly from a brand that is copy the brand name Lifeproof!

There will be an increasing range of choice of Galaxy S9 battery cases available and we will update this list as that happens. However, all these Galaxy S9 battery cases have relatively identical user experiences. They are just different brands. The key differences:
1) Bulkiness - there is considerable weight gained by attaching any of these Galaxy S9 battery cases to your phone. The issue is they are permanent additions and when they are depleted of power you still need to carry the bulk for the protection they offer.
That means you are carrying around something you do not need most of the time. This is not the case with the i-BLADES Galaxy S9 Smartcase. You can remove the battery and memory Smartblade when you no longer need power.
2) Battery capacity - this is a challenging one as most people feel they need more battery capacity? But the reality is most need enough power and battery only for certain periods. If you want days of battery life you will normally go for a big case like the Zerolemon Galaxy S9 battery case. But i-BLADES has a smarter way to deal with longer battery life as you can stack and charge multiple smartblades at one time and then just add that extra capacity when you need it.
3) Function - Every single Galaxy S9 battery case offers you battery power. The i-BLADES Smartcase is the only one to offer you much more: more storage; a built-in air quality sensor so you can monitor air quality; more Smartblades are coming soon including better audio.
See below how the i-BLADES Smartcase has stacked up against the market leading battery case on previous Galaxy smartphones.
