This is the best battery case I've ever used.!!! My phone no longer goes dead mid day, and usually has power left at the end of the day. I'm very happy with it as this is a business phone and is constantly being used. GREAT!!!

Extension for the headphone jack isnt sturdy. It's too flimsy which allowed the cable to break making my headphones cut in and out. Charging works perfectly, and other than the hefty size of the case it's not bad. Starting to see battery cases with the same battery size come in smaller cases which look more pocket friendly. Look around before buying this one.

It can take your iPhone from 20% battery life to 100% and still have enough charge to get an additional iPhone from 20% to 45% battery life. Great case.

Getting a case like this one - big and with space around the phone - changes the experience of having the phone. It's obviously very protective but the small, slim size, one of the reasons people buy the phone, is changed.Also, the charge on the case, which had initially lasted for 12-14 hours with no need for recharge, is now dissipating more quickly and after 8 hours or so needs recharging, about how long the phone lasted before the battery case. This may be an artifact of this case, something having to do with my use of the phone, or something else - and it may well be fixable, I'm just reporting it now. But if it isn't fixable, then I would not have bought the case.

I was so hopeful for this case, but if you want to charge everything at once- good luck, it takes almost a whole day! Therefore you have to take case off and charge phone and case separately which is inconvenient to say the least.

This case is an excellent protective product. It is heavier and bigger than expected. Therefore, it is a bit cumbersome. I am having difficulty plugging in the ear buds. I do appreciate the back-up battery aspect. I would probably buy something else next time. I was too worried about battery life.

It stopped working after only a couple of weeks. I have not reached out to manufacturer yet but I am planning on doing that today. While it worked it was awesome!

I love this case! It kept my phone charge all day at Disney World, where I was taking pictures and using the DW app. When we left the park at 10:30 pm the phone had a 94% charge!

Just plain awesome. Having double the battery life and great protection for your device at the same time is amazing
