ElephantStory 5000 mAh Battery Case for iPhone 6 6S 7 8, SYNC Charged with iPhone, 4.7 Inch Slim Rechargeable Extended Backup Battery Pack

Lets me use my iPhone 6s all day. The phone by itself wasn't holding a charge but for a few hours. Now with this back up battery and case, it is well protected and charged all day. To activate the charge, just push the button on the back for a second or two. The case will start charging you phones battery while you are using it. When both the case and the phone need to charge again, simply plug you iPhone's charging cord (not provided) into the case. It will charge both your case's battery and your phone's battery. One complaint: I does make your phone bulky and it does not cover the top of your phone over the top screen. I feel if it were to drop in the top, front left or right corner, then it may not protect well enough if dropped just right. Overall, I like this case and it saved me from buying a new internal battery and having it installed which was quoted at twice the price of the case.

This battery case is relatively heavy and bulky. I used to have a Thinner charging case that stopped working. I have used this one for a month so I don’t know longevity. The iPhone slides in, so you can’t lose a top piece like some charging cases, Which is a big deal if you put this in your pants pocket. Don’t buy a charging case with a pop on/off top: they don’t stay on :-D

Pros: many charges, charges with lightning cable, I have used this for several months and it continues to work great, it charges fast and puts out a lot of power when only partially charged. Power the case on or off to enable or sizable charging, also, you can charge the case and the phone simultaneously.Cons: no front screen protection (I dropped my phone and my screen protector shattered), a little finicky with charging, meaning that the lightning cable fits loosely into the this case so make sure it is stable when charging.

It has been a couple of months since I received and started to used it during a travel to Europe. It might take 3-4 hours to charge both the phone and the case and with it you will get 3 full loads. Easy to install or remove, nice looking.On the other hand, you will feel more weight in your pocket for sure (3X compare with the normal phone weight) , so consider it if is an important fact to you. Also, the edges do not protrude from the screen and may leave it slightly exposed to bumps or scratches, so you need to be careful.Overall I am happy and satisfied with the fit, performance and look.

Had my phone for two years and the battery start to degrade. This battery case is very handy and it fully charge my phone about 2-3 times. It’s very comfortable and it fit my phone perfectly. The case is made with high quality material and very easy to use. Now I can going out without worrying my phones’s battery

Does what it says and provides ample backup power to recharge your iphone. Be prepared for a heavy phone -- that's the nature of adding 5,000...but it's well made and works as designed.

It has held up fairly normally after a month of use , that said ,the fireplug jack has gotten completely lose so the charging cord falls out on its own if the unit I see not rested on something flat. Thats a problem.

My iPhone battery was draining quickly. I was told that my battery did not need to be replaced. This case totally solved my issue. I highly recommend it for anyone with similar issues. A bit heavy, but worth the “weight”.
