Last but not least, we'd recommend those with the Galaxy S7 or Galaxy S7 Edge get a portable battery charger for their device. Those who can't afford an expensive Samsung or Mohpie battery case, should get a nice 10,000 mAh portable charger that supports Quick Charge 2.0. That way it will recharge the Galaxy S7 three times, 100%, and do it as quick as a cable charger from home.
This is potentially the best route to take, as battery cases can be bulky. Until more cases are released by manufacturers, we'll only suggest the few here, and recommend all user users check out these great Quick Charge Portable Battery Chargers.
