Customer Ratings & Reviews

The battery in this thing is great. I love that all I need to do is switch the button and the battery starts charging my phone. I like that when you charge your phone at night it charges the battery simultaneously. I don't like the fact that the case is not very resistant to wear and tear. I dropped my phone not long ago and now there is a crack in the screen. no cushion whatsoever for the phone.

The biggest downside of a Galaxy S4 phone is battery life. The Mophie Juice Pack solves that issue. It doubles the life of the battery between charges. The case feels nice in your hand and has just enough texture to help keep it from slipping. I have two issues with the case. First, the hole for the headphone jack is too small for many existing cords to plug in. Second, it tends to heat up quite a bit while the case is charging the battery.

Recently promoted and using my cellular much more than before. Battery life became an issue. Heard about this case that 'charges' your phone with the flip of a switch. IT WORKS! The only issue I have is that while it is charging it is to hot to put in my pocket. Once the charging is complete it is fine. Overall, great product - worth the money and I would recommend!

I have purchased a mophie battery extender for my galaxy phone. I needed to be able to work in the field or travel without losing my battery. The Mophie gives me peace of mind so I can focus on the more important matters in my day. I would recommend Mophie products to any one. I can't wait to try the memory extender.

If you need more battery life for your S4, look no further. This has been a great device. I had some issues getting it to charge in the beginning but that was due to the cable that I was using. I changed my cable and have had no issues since.

Love this product! Phone stays charged all day and night. Just what a busy mom needs. Very stylish and matches my white galaxy perfectly. Luckily I have not dropped this, so can't share any result of that. Charging both at the same time goes quick too!

I think its great! its with me all the time, due to im always on the go and don't have time to charge my phone. it only gives your battery 80% charge but that's ok when you need it in an emergency ( like I do at times) and the white case is cute.

I bought this for my Samsung S4 because by the end of the day, my battery was always dying. Now, I never have that problem and I don't have to hurry to find a charger. Love this concept, I just wish it was a tiny bit lighter/smaller.

My battery used to only last me around 8 hours when I heavily used my phone. Now I can easily get 12-14 hours with this case. It feels good on the phone. The case adding bulk actually makes the phone easier to handle. The only drawback is charging the phone while the case is on takes forever because the case is charging at the same time. But a nice option to be able to do that. It is worth the money!

Thise is a great way to have a nice case on yout phone and even better,you can go twice as long between charging,comes in handy if you find yourself without your charger

The Mophie has proved invaluable when traveling. The 70% to 80% extra battery time is wonderful. A bit of advice, though. It works better to keep it turned off until the phone gets to 20% charge, and then turn it on to recharge the phone. Also, turn it off when recharging it and the phone from a charging cable. It will recharge faster. The paper work that comes with it is not clear on this.

This case is great for battery life but definitely adds to the size of your phone. If your phone is dead by 3 in the afternoon, this is great for you!

Adds another 50 to 60 percent of battery life but still gets me through the day. The case covers the edges of the phone to protect if you drop it.

I have been having problems with my battery life on my phone and I went to the Best Buy in Mesa, AZ to see if they could help me with the battery life of my Samsung 4. They suggested this product, and when I got to the cash register it was even on sale!!! It has more than doubled my battery life and made me a hero with my nephews who get excited when they are playing games and the battery is getting low and I all I have to do it flip the battery charger on!!

This is no bigger than an Otterbox case & offers good protection as well as the extended battery life.

I was looking for a stylish and extremely functional way to increase my battery life while on the road. The Mophie doesn't disappoint. All I need to do is flip the switch and I've got almost another day of usage without worrying about charging. I highly recommend this unit if you need a few more hours of operation. Can't go wrong especially when it makes the phone easier to hold due to the non-slip texture. Run out and grab one now!

Great to have the extra battery power when you need a recharge. Case is nice too.

I was introduced to this by a co-worker and found it to be a great addition to my phone on those long work days. It will fully charge your phone to 100% and the case is slim enough that it does not feel as if anything is there. My battery drains fast because I am always surfing the net, watching a movie or listening to NPR. This is a lifesaver

Second one I bought for my second son. My husband wants one next. Extra battery time is always needed and stays charged so that I can get in touch with my son when i need to with no excuses Bought one for my nephew for xmas. So far invested in 3 Great buy.

I bought this because we were going to a Theme park and wanted the phone to last. This was a GREAT investment. Everyone in my party's phone died but mine kept ticking with the external battery. I was able to capture those pictures that others couldn't. :)
