I've purchased the white smart battery-case for iPhone 7. The apple smart battery works fairly well, as a battery-pack. However, as a case isn't as intuitive, or has the quality you will expect from an Apple pruduct. The case is a disappointment; the silicon surface absorbed colors from fabric and dirt from the surroundings. Additionally, it started chipping in the corners (chunks of silicon material fell off), at least mine did within two weeks of use. Best Buy, will not exchange it, since the purchase took place over 14 days. I was told to deal with Apple directly. When you spend $100 you expect better quality and service. Positives: good backup-battery pack, works and fits well, it has a nice feel, and it's fairly light Negatives: case chips easily, discoloration, the white case easily absorbs colors and dirt from the environment, expensive, poor support/service from Bestbuy and Apple.

Had it for a year and while the battery still holds, the material is just falling appart and it seems to be a design flaw since my coworker had the same problem. Here are some pictures from my phone snd my coworkers phone. Not a good purchase, specially for the price.

Although the case holds a good charge, it lacks many of the features other battery cases have. The battery case has the worst wear and tear I have ever had on a case and I have had it for less than a year.

This battery case is almost perfect. My wife loves it. It looks good functions well but it is not durable. This is her 3rd case in 3 years. The plastic starts to wear and starts tearing off. My mother in law has the same case and saw the same problems. Look online to see the issues. It functions perfectly with the apple ecosystem by displaying the amount of battery left in the case on the phone itself but it just is not durable.

I am currently still using an iPhone 8, which this case fits on perfectly, and was starting to notice a decline in battery longevity. I purchased this case and have now been able to reduce charging from every 12-24 hours to about once every 36-48 hours. Great buy if you're looking to extend time between charging!

I absolutely love this case. I use it daily and it holds the charge from the moment I wake up (3 am) to late night. Even at this point with heavy use, I usually still have some charge left. The only negative thing is that my last one broke on the corner but that was because I dropped it. Although still fully functional, I did buy another. Now I have one for when Im working and one for when I'm going out. Cause yes it looks that bad. I highly recommend this case to anyone who uses the Internet a lot especially those like me who watch constant videos online or those who rely on their phone for gps all day. Life saver.

I wasn’t sure if this would fit my iPhone 6s but it did. Camera view is unobstructed. Only thing is I cannot use plug in earphones with The case but that is not a problem for me. I don’t use earphones. If I did I could just take the phone out the case. I was happy to get this because Apple doesn’t make battery cases for iPhone 6s phones.

Holds charge. Almost doubles battery. And redirect speakers so u have two front facing stereo speakers. Only worth it on sale.
