The Smiphee iPhone Battery Case is an ultra slim, portable charger that can extend the battery life of your iPhone X or iPhone XS long enough for it to last a full day. The case has a battery capacity of 4000mAh, which is great for anyone who tends to spend a lot of time on their phone and is too busy to put it down for charging. The charging case is also quite well designed compared to other options in the market, and is available in either color black or rose gold. These are just some of the highlights of the Smiphee battery pack, so if you need to find out more about what it\u2019s got to offer, feel free to go through the rest of this review, and find out if it's one of the best iphone battery cases for you.\r\n\r\nWhy We Like It - Smiphee iPhone Battery Case Review\r\nThe Smiphee iPhone Battery Case is a sure win for the iPhone user that\u2019s always on the move, and doesn\u2019t have the time to always recharge their phone when it dies down. And if you're into Blackberry phones, this review on the Blackberry\u00a0Z10 set to launch on AT&T, march 22nd is a must-read.\r\n\r\nPerformance\r\nA battery capacity of 4000mAh means you\u2019ll be able to have more than ten hours added to your phone\u2019s battery life, and keep your Apple iPhone on for as long as you need to use it. This is more than the combined capacity of the two 1430mAh batteries that the Apple Smart Battery Case has, making it a much better choice than the latter. The Smiphee iPhone case is also supported by all iOS versions from iOS 10, so compatibility should not be an issue. The bumper and hard shell back-plate prevent & absorb any impact from falling to the ground, and with no excessive bulking, the case maintains a slim design that makes it easier to store or hold.\r\nDesign\r\nSliding your phone into the Smiphee battery case is very easy. All you have to do is bend the soft top part, and you\u2019ll be able to slide it in without any problems. The case simphee also has a soft inner patch so that your iPhone\u2019s glass back remains nice, smooth and free from any scratches. Just like the Trianium Atomic Pro Review 4200mAh iPhone Battery Case, the Smiphee case comes with a power button at the back that\u2019s next to 4 LED lights, which let you know how much power the case has. You also won\u2019t get a charging cable with the battery case, so the manufacturer asks that you please use the original one that came with the phone, instead of a third party charger.\r\nValue\r\nThe Smiphee battery case comes with a 12-month guarantee for assurance of quality, so that if you ever come across an issue during your first year of purchase, you remain eligible for a full refund. Bear in mind that you won\u2019t get that kind of policy with the Swaller iPhone Battery Case. Other than that, a couple of things you should know about the smart battery is that it does not support wireless charging, and that CarPlay doesn\u2019t work with it either. On the flipside, the case does support sync-through technology as it is able to charge and synchronize files from your computer through the same lightning cable.\r\nSmiphee iPhone Battery Case Review Wrap Up\r\nMost battery cases that you\u2019ll find in the market right now won\u2019t even offer you as much talk time as you\u2019ll get with the Smiphee iPhone Battery Case, so if you\u2019re looking for a battery charger that\u2019ll keep you going through your day, it\u2019s really the one you should go for.
