    A nightmare to remove!!

    I always enjoyed using the Mophie Juice Pack. Functionality-wise, it gives you the extra power needed to ensure that you get through the day on an otherwise questionable phone battery. I've owned such a case for nearly every phone I've ever owned. My current phone, the Samsung Galaxy Note 9, was supposed to be no exception when it comes to slapping such a case on. While the case does work well as intended; what no one seems to have mentioned, is that when you want to REMOVE the case from the phone, doing so is a total nightmare! I followed the instructions precisely, and the phone did NOT want to budge. It got to the point where I was pushing and pulling on the phone with all my strength, all while trying to keep that top half of the case pulled back away from the phone. I was pushing my thumb upwards from the bottom of the phone so hard that I inadvertently slid my tempered glass screen protector out of alignment, essentially ruining it! By that point, I was genuinely freaking out and only after my adrenaline spiked, was I finally able to get that case off. I was seriously afraid I had damaged the phone itself in the process. Miraculously, that didn't happen. Bottom line, stay away from this case at all costs unless you plan on leaving it on the phone 24/7 forever. Suffice it to say, I returned it. I wanted to like this unibody design, I really did. But now I'm wishing they had kept the two connectable upper and lower case halves they normally use in their Juice Pack cases. At least with those, you get good leverage for both insertion AND removal without fear of burning a couple hundred calories and shouting more expletives than a sailor trying to take it off!

    Case is built tight. It provides good impact resistance. Provides a really nice firm non-slip grip. Recharging is simple. Just press the button twice and it'll start charging the phone. However it does not provide a true one-to-one connection from C connector of the phone to C connector of the external juice pack for some reason. If you want to use Android Auto don't get this juice pack. If you want to use Mirroring or the DX function don't get the juice pack. None of these functions will work with this case attached. I spent days troubleshooting, Best Buy spent a few hours trying to figure it out. Took the Samsung Galaxy Note 9 out of the juice pack and everything worked. Android Auto, Mirroring and DX. Put phone back into the case none of functions would work. Additionally wireless charging causes the back of the juice pack to become very hot! In just 20 minutes time providing minimal charge in the process. I would not recommend this to anyone that wants to use any of those features. But if you're looking for a good battery pack to get you through a tight spot this is the one.

    Very slim and premium looking

    How slim is this case? Well, this is the first battery case I've ever kept on any phone 24/7. And as a hiking/climbing leader, I've been buying battery cases ever since Samsung infuriatingly decided to make their batteries non-removable after the Note 4. The case certainly adds weight to my Note 9, but it adds much less bulk than I expected (compared to my slimmer Samsung-branded rugged case). Pros: Slim profile and premium feel --Cutouts amplify speaker volume --Both wireless charging AND passthrough charging via the case saves wear-and-tear on my USB-C port --Charges the Note 9 quickly, via battery or pass-through (1:59:00 for the latter) Cons: Price (Yikes!) --Battery capacity (Only adds 40% charge to my Note). --Charging case wirelessly will top off phone but will not top off case (even after 6+ hours). But it's still a really cool function to have.

    Great feel to it, light and doesn't add crazy bulk to an already slim design. I've used Mophie products for many years and expected this product to deliver. Plus: USB C plug in, Q Wireless, light weight, fully charged phone in morning with fully charged case should get you through the day no problem. Cons: battery test took my Note 9 all the way down to -5%, turned on the Mophie case and it charged me back to -40% and was done. Come on now I expect at LEAST 1 full charge. Priced at 89.00 from Best Buy normal price for Mophie cases, hasnt been in stock at store since purchased. This is my daily case I would recommend but just know youre only going to get about 40% charge.

    I'm the type that forgets to charge his phone every once in a while, so this case is practically a lifesaver. HOWEVER: if you plan on using your phone for Samsung for Dex, keep in mind that the way the charging port is set up will not allow you to use the type C to USB A adapter that came in the box. Lastly, keep in mind that the battery backup itself is only around 2500 mah, just over half the battery capacity of the Note 9 itself, so don't expect to get a full charge off it. Other than that, a swell case,

    Great for some extra battery but dang that bulk

    If you need extra battery, this is a great case for you. But if you hate added bulk or weight, avoid at all costs. It makes this beautiful thin phone feel and look like a brick. I also experienced some issues while trying to charge both at the same time. Once the phone was charged, sometimes it wouldn’t continue charging the case. I had to press the button on the back. I ended up returning it because the added battery life didn’t justify the added bulk for me, personally.

    This battery case is a must have for anyone who is away from a charge source for long periods of time. I typically need to charge my more 9 after a couple of hours of heavy use. Stinky press the small button on the back of the case and wow withing an hour my phone is fully charged again. I now have a little over twice the battery life without having to find a charging source. The case is now designed so that using your finger print is easy, even for people with longer nails.

    Good to a point for extra juice when needed

    Gives an extra boost to the battery if you forget to charge phone and busy. It is not the same size nor capacity as the built in battery as other's have mentioned so not like a second battery but believe it is 35%ish capacity ? The physical size is fairly compact and does not add a lot extra to the phone. Just nice to have that extra power when you need it and no place to charge. Wish the price was less given the battery capacity.

    I love the idea of having the battery charger added to the case. Only concerns were, will the battery charge/drain battery if it's always plugged in? I don't want to hurt the battery life so new into the phone. Will it hurt that, right out of the gate? Also, it's a little too bulky to use daily, if I don't yet need the extended battery life. Mainly planning to use it once my battery life on my phone goes some.

    Earns a 5 star rating despite the smaller capacity

    The same excellent performance I have come to expect from Mophie Juice Packs. I have tried several other brands and wind up back here every time. I do wish the Mophie had a little more capacity as I use my phone very heavily for work, but higher capacity packs interfere with the NFC function and seem to require removal of the pack for wired connectivity to my laptop and for wireless charging.

    Reduces need to carry an extra battery pack

    This juice pack adds weight though trade off is power when running low and you don't want to carry an extra battery pack, charging block and cables. You don't get to 100% though the "back up" charge will get you past 50% enough to get you back to where you can charge your phone. Awesome for those on the road or travelling. I scored this 4 out of 5 as I don't have another product to compare this to.

    I have had past mophie cases. This one is my favorite. It gives you a little more than half a charge. Its slim. One piece. It is matte with grip on it. Very comfortable to the hand. It uses usb-c! The way the bottom fits around the speaker it helps to project sound toward the screen so you don't have to worry about covering the bottom speaker. A win!

    If you are a heavy phone user, this is a great case to have. Adds another 2500mA to the phone, to go even longer between charges. The other day I went nearly 10 hours of screen on time, and could have gone for more (I put it back on the charger when I went to bed). Also, the shape of the case is really comfortable to hold.

    While this battery case functions well and even feels nice on the phone, there is no way the size of the battery justifies the price. I don't often return things, but this product I did because the battery was smaller than what the Note 9 has internally and failed to fill it more than 30% or so.

    I paid $109 plus tax for this charging case that claims to have up to 36 hours of batter life. That is definitely NOT true. This charger only gives me just short of a half of battery. This charging case cost way too much money to not deliver at least one full battery on a charge.

    For an external battery case I feel that this has a really good grip to it as well as a lighter weight than some others I have seen. It isn't extremely bulky which was what one of my concerns with this type of case was. It slid right on the phone with ease and holds battery life well.

    Good battery case. Gives an extra 50% battery increase. Quality is good. Drawbacks are my Samsung wireless chargers (including the new DUO) only charge the phone to 100%, will not fully charge case. Another issue is the USB will only charge, cannot use DEX, sync, plug adaptors in, etc.

    I work long shifts and often dont have a place to charge my phone. This case is great! I highly suggest it for anyone who works long hours on their feet or for anyone camping or hiking and doesn't have a power source available.

    After having the case for almost two weeks, it would only charge my phone 30-40%. Then the case would die. Not even enough to make it worth tuwning the case on or putting up with the extra weight or bulkyness of the case.
