The new Samsung Galaxy S6 and S6 Edge are great phones, but their reduced battery size can be frustrating for some. As a recap, the Galaxy S6 has a 2,550 mAh battery, while the Galaxy S6 Edge has a 2600mAh battery. Both of these batteries are smaller than the battery in the older S5, which boasts a 2800mAh battery. If you own an S6 or S6 Edge, and want to extend your battery life, you have a couple of options. You can keep a portable battery pack in your bag, to top off your battery throughout the day. But another option that many people prefer is a protective case with a battery built right in.

(NewNow)

This battery case has enough juice to fully recharge your S6 or S6 Edge, with a decent amount of battery life left for another top-off later in the day. It’s relatively thin, compared to some other battery cases out there.

To tell how much charge is remaining in the case’s battery, you simply look at the LED indicator lights. Four LEDs give you an estimate of the charge remaining, from zero to 100 percent charge. These cases are available in black or white, in your choice of folio-style case or “regular” phone case style. This case is designed to prevent overcharging, which could damage your device.

Price: $23.99

3. Roger 4200mAh Samsung Galaxy S6 or S6 Edge Battery Case

(Roger)

This inexpensive battery case is a good choice for S6 or S6 Edge owners who are on a budget. The battery case for the S6 Edge lacks the front folio cover you’ll see on the S6 option. Like other options on this list, you can make use of an LED indicator, over-charge protection, and a kickstand. It may not have much in the way of bells and whistles, but it’s a great “placeholder” battery case you can use until a battery case in cooler colors comes out later this year.

Price: $18.39 and up, depending on model selected

(Sykiila)

At this point in the list, you’d be forgiven for thinking that all these cases are starting to look the same.

Otherwise, this case is similar to the other items on this list. There’s a kickstand, LED indicators, charge and sync capabilities, and overcharge protection. The carbon fiber skin is a nice touch because it offers a nice texture to grip, as well as a surface that is somewhat resistant to fingerprints.
