Best Battery Cases for Samsung Galaxy s7, s10 and iPhone 6, 7

If you’re thinking about purchasing a new case for your Samsung Galaxy or iPhone, you might be better off with a battery case rather than a traditional phone case. The difference is that a battery case not only protects your phone’s internal components from accidental damage, but it also comes equipped with a built-in battery pack as well.

A battery case is a perfect accessory to have if you travel to remote areas without any electrical outlets in sight. It gives you the ability to extend your phone’s battery life up to another 39 hours. Of course, it all depends on how much demand you put on your battery. If you watch videos or browse the internet on your smartphone, then you can expect another 22 to 22 hours of battery life with a battery case connected.

There are different battery cases available for the Samsung Galaxy and iPhone. The one you choose depends on your phone’s model number and the energy storage capacity you prefer.
