Maxboost iPhone 4S Battery Case/iPhone 4 Battery Case (1900mAH, Fits All Versions of Apple iPhone 4 & 4S) - Detachable Battery Charger Case External Rechargeable Battery Pack Charging Power Case

Bottom line - for $10 with free shipping, you aren't going wrong with this product. That said, while I get compliments on the appearance, there are some things that aren't terrific.First, the battery loses some charge fairly quickly. That's not a great characteristic.And there are two shortcomings with the case that holds the phone. It appears to be molded in a clear polycarbonate or another brittle plastic, then powder coated or painted with a high gloss finish. The finish on the phone makes the case very slick, resulting in it getting dropped much more often than when I use my regular case (which is made from a more flexible plastic and with a neoprene or similar finish). And when it's dropped, the stiff plastic chips and fractures.The stiffness of the material made it a bit difficult to get the phone in and out of the case (at least until one figures out how best to do it - read on) and the stress of removing it the first time cracked it at the thin spot on the side next to the volume controls on the phone. Turns out the trick to removing it, avoiding the stress crack, is to flex the side *opposite* the controls (insert a thumbnail into the right side as you look at the screen), and then push the phone over the lip of the case by putting your finger through the key hole in the back where the battery itself is secured. Snapping it back in by sliding the left side in first turns out to be quick and easy.Like I said, for the price it is fine. If they were to address the battery performance, and the plastic and coating, it would be a terrific value.

Hubby's iPhone 4 that he uses just for Sp*tify and other music would only hold a charge for an hour. This great little case frees him from dragging around a portable charger. He says he never has to charge his iPhone 4 except at night like his iPhone 5s. Another great benefit is that since his phone is so small and he has large hands, it makes the phone a touch bigger, adds a little heft, and makes it much easier for him to grip. If he does drop it, it adds a bit of protection. I would recommend this great case to anyone still using an iPhone 4.

The phone case came on time and it is as described. It fit my iPhone 6s perfectly and I love the on /off switch it has, it is a nice option. most other cases don't have this switch. The price is great for such quality. I would recommend this case to my friends.

The adapter to plug the battery case is faulty. When I plug it in to the phone, I have to jiggle it before it will start charging. The battery case (once I can get it charged) works so far, but I would not recommend because of the adapter.

requires use (provided) separate charging cable and sort of bulk / brick appearance but (so far) holds the charge for a couple days.

Bought this for my daughters 4s and she loves it. I do too. Battery works as advertised, it’s very durable, and my daughter loves the look. I’m going to look into additional products from this company for our other iPhones.

Purchased June 1, 2018 to use my iPhone 4 as an iPod. Product worked great for about six months. Unfortunately even though it still charges and connects tightly to phone, the phone will not recognize or accept the charge!! Have submitted inquiry to Maxboost support, see if they answer. In the meantime looking for alternatives instead of tasing my money with this brand.

Is really pretty and keeps my old iPhone 4s going
