The Best Battery Packs and Cases for Pokemon Go Players

Pokemon Go is a horrible battery suck. These cases and backup batteries will help you

Pokémon Go is hell on your cell phone's battery. Because it's constantly pumping the GPS, LTE radio, and screen, we've seen battery drains as fast as 1 percent per every two minutes while playing.

Since most phones nowadays come with sealed-in batteries, a battery case or backup battery may become the hottest real-world Pokémon Go accessory. Battery cases are more expensive and often hold less charge than backup batteries, but you don't have to tether them to your phone with a cable. Backup batteries have more charge per dollar, they work with all phones, and they work with more durable cases than battery cases.

I generally use a backup battery that I stick in my pocket and attach to my Galaxy S7 with a MicroUSB cable, but I'm a dork.

Different devices need different cases and batteries, so you don't have to catch 'em all—just those that works for your phone. Here are some of our picks.

Boostcase for iPhone 6The Boostcase for iPhone 6 (right) is our current pick for the best iPhone battery case. Its innovative design lets you detach the battery when you don't need it, so you don't have to carry the full bulk around with you.

If you intend to keep your battery case on all the time, the Mophie Juice Pack Air has the most attractive design of any of the cases we've looked at. Both Boostcase and Mophie also make cases for other iPhone models as well.

For the Samsung Galaxy S7, the best bet right now, purely battery-wise, is Samsung's own Galaxy S7 Wireless Charging Backpack. While Mophie's cases sell for their list price of $99.99 on Amazon, I'm seeing the official Samsung case selling for half that. Reviewers warn that it does absolutely nothing to protect the front of the phone, though, so don't think of it as a protective case, just some extra juice.

If you want to Pokemon all day and all night, ZeroLemon has a string of gigantic cases for popular phones with gigantic built-in batteries. They're bulky, but the ZeroLemon Galaxy S7 model has 7500mAh on board, which is more than two full charges. I would find a phone in that big a case pretty hard to handle, though.

It's harder to find a high-quality battery case for many less expensive Android phones, so owners of those phones may want to go with backup batteries instead.

UNU SuperpakThere are many backup batteries out there, but we're impressed with the UNU Superpak, which runs only $29.99 at Amazon. At 8 ounces and 0.8 inches thick, it's quite thin and light for an impressive 10,000mAh of charge. The Superpak has two ports for 1-amp standard charging and 2.1-amp fast charging, and it comes with a combination Lightning/MicroUSB cable to charge Apple and Android devices. The whole thing charges in about four hours.

Since we reviewed the UNU Superpak, the Anker Powercore 10000 became available. It's even lighter, at only 6.4 ounces, and it has an 18-month warranty and a reputation for quality. It only has one charging port and comes with a MicroUSB, not a Lightning cable, but that should be fine; if you have an iPhone, you probably have a Lightning cable anyway.

All of these products are available with next-day shipping, so grab one and go Pokémon hunting.
