Customer Ratings & Reviews

This phone case is strong and protective for rugged use. It has a built in charging system to lengthen the time between phone charges. It has probably added half again how long the phone stayed charged. Because it was a very good price, it was worth it. I wouldn't have spent the full price for that much more charge.

I bought this bc my battery only lasted till lunch time if there was heavy use. I can use it all day long and the battery will last into the night. At first it lasted 2 days. During a week day it will last about a day and a half. Over the weekend, when email use is less it will last 2 days. I bought the belt clip separately. The case is showing wear on the edges that never showed up on my regular defender after almost 2 years.

Had to return the first one I received as the case wouldn’t charge my phone. However, I was able to return it for another that works well! Thanks.

Case is good and definitely extends phone use but right after buying IFAD to by a new charger cord due to the original would not charge phone

Excellent cover with battery charger. Good peotection

Let's face there aren't a lot of great cases out there for an iPhone 4s, so I was optimistically hopeful when I purchased this case. Unfortunately, the case was a dud. I never could get it to charge. It also caused my volume to automatically adjust to the highest setting. I wound up returning the case.

I saw this incredible deal on a case with a built in battery for about $10 vs about $125 new...so I got one! The first one came and didn't work at all...so I returned it..they ordered another one and got it in a week or so... This one worked...but did not give double my Iphone's life as expected. 30% more life was more like it... But- if you need a case...and a battery- I guess for $10 you can't beat it.

Don't not buy this case Probably the worst case I ever bought

Awesome all in one case. Keeps my phone charged for a couple days and very well protected!

I gave my Dad my old iphone4s after his flip phone broke and bought him this battery case for it. My Dad tells me he don't need to charge his phone everyday like he did before. It's more like every 3 days. I'm so glad I was able to find him this battery case at BestBuy.com and at a great price too. He's happy. I'm happy.

This is a heavy case for the iPhone. If the battery worked as advertised, I would add another star to the rating.

The case does exactly what it says it will do. It keeps charged and keeps the phone charged as well

Not even close to what you would expect from an otterbox product... Do not buy this !!!

great buy from Best Buy, love this phone case and the built-in battery

Battery drained faster and the backup did not engage. Not sure if this site was defective, but I was not pleased with the item and returned it to the store.

Awful. Would not charge at all. Returned both cases. But the service was great. No issues returning

My IPhone is three years old and the battery doesn't stay charged all day so I bought the Otterbox external battery. I really like it, haven't had any problems with it!

Battery charges with android charger so it works well.
