    I love this case. Gives a lot of extra battery life and doesn't add much weight to the phone.

    The case battery does help keep your phone charged throughout the day, even with heavy use. Unfortunately when you do plug up your phone up, the phone will not recognize the cause and will not charge. You then have to shut the phone off or remove the case and try again. Besides that it’s a decently good case.

    I’ve had this case for close to two weeks now and I have to say it has reached way over expectations. I put the case on my phone the moment I got it and I am on my phone frequently and I have still yet to use my phone battery. I do plug my phone in often when I am driving but even by the end of the night my phone is still running off the charging case. Highly recommend

    Adds more weight than the iPhone itself. Other downsides are that you can not control when to use battery from the case, it just keeps charging all the times, and it is definitely pricey.

    It kept my phone battery fully charged throughout the day before it started to use the phone battery. However, it does add heft and makes it more difficult to take it out of my pocket. I ended up returning it.
