Poor design - side buttons

Dislikes:1)The sides of the case are not rigid, especially right at the buttons. This causes the buttons on the side of the phone to be depressed with the slightest bump or nudge. Phone is constantly taking screenshots as a result, not to mention dropping calls.2) the indicator LEDs never turn off when charging, so if you charge your phone/case on your nightstand at night like I do, the LEDs light up your room.3) case is not compatible with wireless charging.Likes:1) good extended battery…

  • user guide
Cons
  • Expensive compared to other charging solutions

One of my best purchase in amazon !

Hands down this is one of the best purchase ever. I used to talk a lot using my phone and always worried about the OEM battery. never had used a battery case before. Thought I should give it a try. I received my battery case for my iPhone very fast in a nice package. It fit pretty nicely and the installation was pretty easy. My iPhone kinda looks good as well with the black case. It is not bulky and doesn’t feel heavy. And a battery indicator is a plus. Overall I am extremely happy with my…

Great case for extended battery life

As the title states, this is a great purchase if you are somebody that finds themselves draining their phone battery early in the day. I used to have to charge my phone around mid day as I run a business on the go through it. This battery pack case allows me to not need to lug my cable and charger box around so that I can continue to work. Its also not nearly as big as other battery cases are. It keeps the sleek and slender look of the phone. This will allow you to use your phone all day long…

Pros
  • Longer Battery Life
Cons
  • May not charge your phone to 100%

Read this review. for my opinion

If you don’t wanna spend $100 on the apple battery case, this product is good. However a few things you should know. Since it’s not made by Apple, you iPhone might not accept the charging port and when it does that it won’t work.For me that’s exactly what happened. I finally got it to work after restarting my phone and the case multiple times. Kinda forced it to work.

Pros
  • The battery case is an immediately effective, easy-to-use charging solution that requires no extra effort
Cons
  • May cause your phone to become unresponsive

I had the old version of this and used it for a longtime on iPhone X, later saw this new one was released which is sleek comparing to the older model and even charge faster then the older version.Having this make using the phone all day without any issue , it even goes beyond 2 days if your screen time is lesser during the days.I have been hearing music and watching videos quite heavily like almost 5 to 6 hours in screen time, which can be easily achieved by having this and even it doesn't make

Pros
  • The case feels comfortable in your hand, offering a snug and secure grip
Cons
  • May not be easily cleaned

Really great Product

Really great cover battery case. It protect the phone really well on top of providing a really good charging that give of 100% charge again which is handy when you travel, or work for a long day. I owned several cases before including mophie but this one is the slimmest in my opinion and the quality of materials are really top notch. I truly recommended for anyone who need a case since this one seems the one for me that will last the longest. :)

Pros
  • Important Note
Cons
  • May add unnecessary weight to your phone

Good product on my review.

First of all, i want to apologize .I did write a negative review couple Of months back saying that the product does not work.I found out today that the problem was not in the product, buy my phone. This was due to lot of dust particles inside the lighting socket on my phone. Once I cleaned it, the product works well.Swaller reached out to me and refunded the amount too. I am sorry about that. I would like to return the amount to the manufacturer. Please let me know how to do so.My friends liked

Pros
  • It fits my phone perfectly. It keeps my phone charged.
Cons
  • Bulky design makes it difficult to hold and use the phone

Exceeded all expectations!

I used this case for my iPhone X and it was better than i had thought it was going to be in almost every aspect. My phone lasts twice as long since it's a whole extra battery connected to it i can turn on whenever it's needed. It's really comfortable to hold and there is an extra weight that some people say they dislike but i think it's more comfortable to hold because i can feel it's actually in my hand or in my pocket. Taking the case off is also pretty easy but sometimes putting the case…

Pros
  • Cases, Holsters & Sleeves
Cons
  • May interfere with phone sensors

Nice while it lasted

The case and battery themselves are good, I’m giving it a 4 star due to the charging port breaking and being unable to charge rendering the whole thing useless. If you decide on this one, I recommend being very careful when plugging in to charge.

Pros
  • The slim profile makes for a very sleek and attractive addition to your phone, without adding any extra bulk
Cons
  • May require frequent updating or resetting

Good but not great for my opinion

Case is great, but port for charger is too deep. Never gets charged all the way once it's plugged in because the slightest movement disrupts the charge. 2nd one I've had with the same problem. Just stick with a Mophie, more expensive but for a good reason.

Pros
  • The slim design makes the product an excellent choice for phone users who want top-notch functionality and sleek aesthetics
Cons
  • May cause static or interference

Mediocre at best good for me

The case seemed to have problems charging at times. Only Apple chargers would work, however after a couple weeks I’d have to change out the cord. Honestly a bigger pain than it’s worth. I removed it from my phone and will go back to a regular case.

Pros
  • The charging capabilities will help keep your phone from dying while you're on the go
Cons
  • May not be eligible for warranty repairs

Reliability and great customer service!

I wanted a back-up phone battery case since my phone dies often at work. This phone case is capable of charging almost to 90% full capacity. I loved the thing! When you charge the phone it charges your phone first then the case. Unfortunately a few days ago while charging it overnight it only charged for one bar. I contacted customer service and they were happy to send a replacement immediately! I got the new phone case a few days later and a happy customer. 5/5 great customer service and…

Pros
  • The product is very portable, which means that you can carry it along with you wherever you go, whether to work or on a trip
Cons
  • May cause your phone to emit more radiation

Charger Great For Traveling

As one who constantly forgets his charger and cords on airline flights, I decided to try the Swiller case. I have a continuous glucose meter that uses my iPhone to report my blood glucose levels. Well I noticed on my last long flight that the app for my glucose readings really sucks up the power and I was freaking out that I might run out of power. When I got back home I immediately ordered this battery case. The case fits very good and is very easy to use. You charge the case, slide your phone

Pros
  • The charging solution provides a convenient alternative to traditional chargers that require a wall outlet
Cons
  • May drain both the battery case and phone battery simultaneously

One day in best in my review

Only had it for a day so I can’t speak to it’s functionality but first impressions are great. The soft feel plastic is better than the apple case I own. All buttons are still responsive through the case. If the battery is even decent in this case I’ll love it.

Pros
  • Cell Phones & Accessories
Cons
  • May not fit properly with certain phone models

This is a must travel!

This was a life saver for my vacations! My phone is always dying and I always need it for ordering uber, Yelp, resys! This case was great, battery lasted. Not too big, fits well in my small purses!

Pros
  • The protective design will help shield your phone from damage that occurs when you accidentally drop it
Cons
  • May not be environmentally friendly

Ok product best in my review

The charger doesn’t work well with any cords but Apple. I can not get a full 100% unless i use the Apple charger. The back of it is scratched up pretty bad and I’m not rough with my phone or drop them.

Pros
  • The product is practical for use in emergencies, helping you stay in touch with your loved ones, even when your phone's battery is almost dead
Cons
  • May cause your phone’s battery to degrade faster

Pros
  • The charging solution is an excellent alternative to a portable charger or a wall outlet, eliminating the need to carry spare power banks or cables
Cons
  • May not be available in your country

A battery case that is truly worth the money.

I bought this as a backup to my certified Apple battery case. Turns out, this battery case is better by far. As a bonus, this costs less than half of the official battery case from Apple. Here are some things everyone should know about this great battery case:1. This lasts longer than the Apple certified case by at least 1/3 more power provided.2. This has pass-through charging which means it will charge the phone first and the case afterwards.3. You can use the same charger for the phone for…

Pros
  • The case is designed to offer all-round protection, ensuring that your phone remains safe wherever you go
Cons
  • May be uncomfortable to use for extended periods of time

Not actually slim: my feedback

The product is actually good, the buttons are clicky and the mute switch is easy to access but the battery is bulky and heavy and adds almost a pound of weight.

Pros
  • Charging & Protecting 2 In 1
Cons
  • Limited capacity may not provide enough charge for heavy phone users

Does it’s job! in my review

This case does its job. It holds its charge for a while and typically gives me at least a whole charge if not more. The case is easier to hold than most charging cases which is convenient.

Pros
  • The charging solution is an excellent safeguard to help keep your phone charged when you need to stay productive or keep your phone handy
Cons
  • May not fit in certain car mounts
