5 Best Smartphone Battery Cases For Androids And Iphones

1.Emtect Power Pouch

A case that fits a wide variety of phones, the Power Pouch from Emtec is more of a wallet-style holder that a case that fits every nook of your handset, but for some of you that will be ideal. Here’s something else in the Power Pouch’s favour: a 6,000mAh battery, the second-largest in this list.

We’ve put this in the Android list but such is the versatility of the Power Pouch you can use it with iPhones too (you get both Lightning and microUSB adapters when you buy one). Of course there’s the added benefit of not having to change your battery case when you next upgrade your smartphone.

2.KiwiBird Slim Rechargeable Extended Battery Case

4,000mAh of power to draw on, a slimline fit, and a rock bottom price – there’s a lot to like about this Slim Rechargeable Extended Battery Case. The model shown is for the Galaxy S6 but if you shop around you’ll find different variations made to work with several of the top Android phones on the market.

There’s an LED power indicator here too and it doesn’t interfere with any of the NFC or infrared functionality on the phone. According to the manufacturer you can get at least double the battery life of your phone with this case attached, and it’s one of the more impressive Android options out there.

3. Mophie Juice Pack

Back to Mophie and the company makes battery cases for Samsung Galaxy phones as well as the iPhone models we mentioned further up this page. For your money you get a 3,300mAh battery that provides up to 11 hours of extra video playback on your phone (by Mophie’s measurements anyway).

The case adds wireless charging capabilities if your phone model doesn’t already have them and it will work with just about any wireless charger on the market – very handy if you have one lying around. Plus, it looks sleek and smart, and has integrated LED lights so you can keep an eye on the charge level.

4.ZeroLemon Nexus 6P Battery Case

If you own a Google-Huawei Nexus 6P and value battery life above form and function then the Nexus 6P Battery Case from ZeroLemon has you covered: it packs in a huge 8,500mAh battery which should theoretically keep your phone running all weekend, so it’s perfect for travellers and explorers.

There’s no getting away from it though, this is a pretty chunky case. Still, its bulk means a lot of protection for your handset, and all the ports remain accessible (including the fingerprint sensor around the back). It’s shockproof and there’s an LED charge indicator and power button on the rear.

5.Galaxy S7 Wireless Charging Battery Pack

If you want the best kit for your phone then it’s sometimes best going down the official accessory route. Enter the Galaxy S7 Wireless Charging Battery Pack from Samsung, perfectly contoured to the shape of Samsung’s latest flagship handset, and offering 3,400mAh of extra battery juice.

The case also doubles up as a wireless charging pad, so when you’re at home you can charge up both phone and case together. The underneath of the case is left relatively uncovered, which means you can easily get at the headphone port and the microUSB charging port when you need to.
