Best battery cases for Samsung Galaxy Note 8

The Samsung Galaxy Note 8 offers decent battery life, but nothing out of the ordinary. Thus, some users may be looking for ways to extend the phone's battery autonomy, and a good way to do that is with a battery case - which, of course, will also protect the handset from eventual drops and scratches. 

While there aren't as many battery cases for the Samsung Galaxy Note 8 as there are for other smartphones, we've found several models that you should know about. We're inviting you to discover them below - the cases are listed in no particular order, and you'll probably notice that they're a bit more expensive than regular, non-battery cases.

ZeroLemon Ultra Power Case

ZeroLemon's Ultra Power case for the Samsung Galaxy Note 8 packs a massive 10,000 mAh battery that can increase the phone's battery life by more than 200%. Needless to say, this is a very bulky (and not particularly pretty) accessory, but that's a downside that you'll just have to overlook if you think your Note 8 needs the battery case with the highest capacity on the market. Unfortunately, the case does not feature an S Pen hole, and you won't be able to use wireless charging with it on. On a more positive note, each ZeroLemon case comes with 1-year manufacturer warranty, and Amazon's 30-day full refund guarantee. 

Mophie Juice Pack Case

The Mophie Juice Pack case isn't as generous as the other products on this list, only packing a 2,950 mAh battery of its own - this means it can increase the battery life of your Samsung Galaxy Note 8 by around 60%. Nevertheless, this is a high-quality case, and it's the only one that allows the Note 8 to be used with most wireless charging systems. The price of the Mophie Juice Pack is on the high side ($99), but at least the case comes with 2-year warranty.

Runsy Battery Case  

The only Galaxy Note 8 battery case to feature a kickstand, this Runsy Case will allow you to conveniently watch videos and TV shows on your phone, hands-free. What's more, the case has a built-in 6,500 mAh cell, so it can increase the Note 8's battery life by about 140%. Sadly, wireless charging is not supported.  

BrexLink Battery Case

This BrexLink-made case is almost as generous as the Runsy one, thanks to a 5,500 mAh battery that will more than double the battery life of your Samsung Galaxy Note 8. The case does not support wireless charging, but it's still a great option if you only have $40 to spend. The BrexLink Galaxy Note 8 case comes with a 2-year warranty.

None of them, battery cases are ass, to big and not durable enough. A USB cable and a power bank is the smart thing to do if you need juice on the go!

Plus, the latter will most likely be compatible with all your future devices...

I've been using Zerolemon cases for 2 years. I ordered 2 ZL 10k mAh battery cases. 1 is still on its way. Too big? Yeah, and the point of it is shear power backup integrated with the Note8. It weighs nearly half a kilogram assembled with the Note8. These are meant for when you know you won't be able to plug in, like a long trip to somewhere. As a heavy user, I keep my device with a sealed battery topped up for preserving the battery, with minimal depth of discharge (DoD) so I can have a sealed battery up to 2500-3000+ cycles instead of the 300-500 because of deep discharging. This is researched: It's more difficult to be using a separate power bank with cables to deal with. I do feel the weight, and I do switch to a Rhinoshield crashguard bumper once I have full power, and slide the Note8 again once it hits 60 to 70%. Again, it's better than using a separate power bank with cables, and eliminates holding two objects around. I think of the ZL battery case as a portable charging dock that's secured onto the Note8 while charging.

Or jump 3 notches up and design your device with a replaceable battery again. The best battery tech currently in existence.

Hay num nuts, they make power cases for just about all phones. I get about 9 hours SOT with my note 8 so no need for a power case.

Stay away from smaller battery capacities. When you keep draining them fully and with higher amps which raises the temperature, they won't last long. A 10,000 mAh often times will just drain half for the day and trickle charging keeps both external and internal batteries last longer.

And that thing makes the phone even looooonger. Absolutely love my Note8. But, the length of the device is too long for my usage. Would love a S8 sized Note. Just me.
