Not What I Expected

First Mophie case I ever bought and possibly the last. I was always fascinated by the idea of having an accessory that protects your phone AND recharges your battery. But once I actually did the math, not really sure if it's worth the price.
The Galaxy S9 has a 3,000 mAh battery. The Mophie case carries about 2,070 mAh of charge. Which means that even with your Mophie case fully charged, it will not fully recharge a Galaxy S9.
The Mophie case that surrounds the Galaxy S9 is very effective when it comes to accidently bumping your phone into hard surfaces or dropping it from a short distance (for example: dropping your phone from a sitting position),but I had hoped there would be more grip to it. The material is a bit more slippery than I anticipated, but if you're looking for a sleek design and don't really care for grip then no worries there.
If you're thinking about getting this case, I strongly suggest that you consider getting an external battery instead that can hold enough mAh to potentially charge your Galaxy S9 2-3 times to 100%. 4 Stars because even though it didn't meet my expectations, still handy if you need that 60% extra battery life.

Excellent quality and battery life. Has protected my phone from damage numerous times. Only downside is that it's a little difficult to take off sometimes. After taking removing from phone for the first time the top piece is now a little loose. Other than that I'm satisfied with product, it is worth the buy and I would still purchase it again.

I have been using Mophie juice paks for a while. As soon as i got my new S9, the first accessory i bought was the juice pak. Not only does it provide great battery power, it protects the phone. I find the new phones feel very slippery and light in my hand and the juice pak adds some weight and texture.

the charging feature is wonderful and so helpful. However, as a case for a phone it is lacking. I have experienced cracks in it after minor drops.

Just the battery case I was hoping for! Fast charging for my Samsung S9, and the wireless charging feature makes it so convenient. At 1st, it feels a bit bulky if you're only used to a silicone phone case, but it still fits in my pocket, and no thicker than an Otter Case. I would even buy a 2nd 1 for my son!

Outstanding Battery Case for the S9! I have more confidence in the use of my phone throughout the day because I know that I have more battery power to fall back to use. There's no need for me to carry around a power cord or to always be charging the phone in the car!

I was skeptical when I first saw this mophie charger case. I was hesitant to purchase but decided to take a chance. So far I have been really impressed with both the protection that this offers my Galaxy S9 and the added charge on the go. great product!!!

I love this case! I don't have to worry about the battery running down during the day. Recently the battery was very low and I didn't have the charging cable with me. I was able to charge the phone from the battery pack.

Bought this external charger to keep my cell battery topped off. Seems as of late my cell battery was dieing faster. So I bought this unit to give me more time between charges. I also wanted one that could be charged using Qi charger.
This one fit the bill. However at times it just guits charging so I awaken to a phone at 85% or worse. Down the road I may have to look for a better one.

looks and feels great in hand. A little bulky but understandably so to make room for battery. You can buy a slim case and battery pack for less $$ if you really shop around if bulkiness is an issue. But mophie is a great brand and I would buy again!

So far so good I really like this case, it had a good amount of thickness not much bigger than a non battery case and feels just right in the hand, it gives you just enough power when needed....got it on sale for $68 makes it a pretty good buy.

It’s great for me as I’m always on the move so there’s times where I would need to charge my phone but I wouldn’t have a charger available to me.. With this case I’m able to charge and use my phone effortlessly on the go when needed.

Galaxy Juice Pack

Purchased the Mophie Juice Pack because I would run out of battery by the end of the day on my new S9! Now I can stay juiced up for the entire day. Feels good for grip although there is no guarantee the screen won't crack if dropped just right. I broke my S7 screen with a Mophie juice pack. Recommend buying glass screen protection too!

Great battery, better design than S7 version

This was a major improvement over the one I had for my Galaxy S7. The S7 version had a bezel that clipped around the edge. The clips would wear down over time and the bezel would pop off. Also, the bezel would pop off every time the phone was dropped.
This new S9 version has fixed this. The phone slides in to a larger sleeve and a cap clicks in securely at the top. The only thing I miss about the S7 version was that it continuously kept my phone charging. This one stops charging when the battery hits 100%. I'm not sure if that is the case, or the phone, though.

I've used mophie cases for years cause I love how I have a full 2nd battery but this case only charged my phone maybe 50% and that's with the case being fully charged. $80 for 50% charge isnt worth it. All my other mophies charged my old phones a good 80-120% depending on the kind. 3 stars only cause it's a sturdy case, I'll give it that. But not worth the $80!!!!
