An iPhone external battery is basically any battery device outside the iPhone that provides additional power to your device. It allows you to charge your iPhone when needed. They come in different designs and shapes to choose from. They will also vary in their battery capacity - that is the amount of charge it can store. The higher the amount of battery capacity, the longer you can use it to charge your iPhone.

So what do you get from having one?

More Usage Time

This is the main reason why external batteries were being made in the first place - to give you more time to use your phone and enjoy it before the battery runs out. One of the things that people are disappointed about the iPhone is its battery life. Because app developers are inventing more and more uses for the iPhone, that can be a pretty big demand for more battery life. Battery apps like BATTERY DOCTOR can help you "manage" and "conserve" your battery life but it won't really "extend" your battery life. Yes it will give you estimated usage times for different activities but it's really up to you how to manage what you have. You will also find other tips on conserving battery life that teaches you to turn OFF certain settings to help save energy. But if that's the case, you won't be able to use some features of your iPhone for the sake of conserving battery. If you want an alternative solution to that problem without having to restrict its use then an external battery would be appropriate for you.

Emergency Charging

Most of the time you will find yourself in instances where you run out of battery and you don't have any access to a power source to charge your iPhone. In these cases, an "external battery charger" can come in handy for you. If you don't like putting a case on your iPhone and still want to extend your battery life then this is a good alternative for you. They are a separate device that you can charge to store power in it. When needed, you just attach them to your iPhone like what you would do when charging. Just make sure that you charge them separately, so they have stored power in them or else it would be of no use bringing it with you.

iPhone external batteries come in different designs to choose from but they do achieve the same result of extending your battery life. So maximize your iPhone and use it to your advantage!

Cheers!
