    "5 stars...Not bad...As a battery case, I give this 4 stars, but for wireless charging I would give it 6/5 RE Battery Case The battery case itself is a fairly slim design, which has the tradeoff of not holding *that* much extra juice....We're not really sure how much protection this case provides, but just based on how it looks and feels, it appears to give a fairly significant layer of security against typical bumps, drops, etc., but I wouldn't go so far as to say it's as good as a high end case designed solely and specifically for the purpose of protection."

    "So good...love it...While not officially sanctioned by Apple, this Mophie case fits the iPhone 7 snug as a glove, and at the same time provides double the capacity of battery power as a battery pack, plus allows you to charge wirelessly with any Qi enabled charging pad (such as the Insignia pad we picked up on the same trip)....I never run out of juice with this case on my iPhone I like and enjoy it very much I recommend it if your phones loses battery fast this case will keep your phones battery charged and protecting your phone at the same time"

    "Not bad...It's ok...One last point is the Apple smart battery case hardly ever got hot compared to a third-party case I had brought off of eBay which did get very hot if even in a pocket for a few minutes....After less abuse that this case has received, a small part of the left side of his case broke (on the morphe) which didn't affect the battery or case protection wise, but he now needs to remove the case to use the left side volume buttons and switch."

    Product Description

    The Smart Battery Case for iPhone 7 gives you extra battery life with the look and protection of an Apple-designed case. Combined with the Smart Battery Case, iPhone 7 provides up to 22 hours of battery life for browsing the web, up to 24 hours of watching HD video, and 26 hours of talk time.¹ The Smart Battery Case also works intelligently with your iPhone to charge simultaneously when you’re plugged in, so both case and iPhone will have more than enough battery life to get you through the day, and then some. The soft elastomer hinge and one-piece design make it easy to put the case on and take it off. You can even connect it to any Lightning accessory, such as the Lightning Dock. And iOS 10 allows you to see the battery status of your iPhone 7, your Smart Battery Case, and even your Apple Watch, all in one place. Available in black and white.

    "Love it...Love it!...Also a good thing to note is, to never place this battery case on a magnetic surface other than any wireless chargers you may have, because doing so will charge the phone and not correctly which in turn will damage the battery case and possibly the phone....I bought the case when I bought my phone, it's a great case to have when you need extra battery and are not near a wall outlet or have your charger."

    "Love it...Love it!...If I had one observation, and it's really a non-issue for me, it would be that the case is obviously a little heavier than a standard case/phone protector due to the battery - but again, I don't even consider this a drawback or a negative....Great for exrending battery life but it really needs a case on top of it as it really offers minimum phone protection."

    "Love it...Good Buy...The Mophie case that surrounds the Galaxy S9 is very effective when it comes to accidently bumping your phone into hard surfaces or dropping it from a short distance (for example: dropping your phone from a sitting position),but I had hoped there would be more grip to it....Also got completely submerged in water at beach and after it dried, it still worked like a charm!"
