The Samsung Galaxy S7 is getting rave reviews, even for its battery, which can charge wirelessly and last more than a day … one whole day! That is, no doubt, one of the many awesome features on this device.
But as we do with any big-name device that hits the market, we spent some quality time with the Galaxy S7 to test its charging characteristics and what they mean for users. Here’s what we found.
The Galaxy S7’s battery capacity is 3000 mAh — about 500 mAh more than the Galaxy S6. If you need even more, the S7 Edge has a 3,600 mAh battery — that’s a 38.5 percent increase over the S6 Edge.
But does a lot more battery require a lot more charging time? Not necessarily. Last year’s S6 could charge from 0 to 100 percent in 75 minutes with our q1200 Quick Charge charger. The S7 took 85 minutes to charge from 0 to 100 percent with the same charger. A 10 minute difference — not bad at all.
Speaking of chargers, the Galaxy S7 in-box charger is the same one that was included with the Samsung Galaxy S6, Note 5, and Note 4. It filled the battery in the S7 from 0 to 100 percent in 87 minutes, indicating that the in-box charger is equipped with Adaptive Fast Charging, Samsung’s version of Quick Charge. Chargers using Qualcomm Quick Charge technology also work with Adaptive Fast Charging.
We should also take some time to debunk a myth. There was some chatter about the S7 charging at up to 3A. That’s not true. It does have Samsung’s proprietary Adaptive Fast Charging (which works similarly to Quick Charge), so when plugged into a compatible charger, it will charge at 9 volts, 1.55 amps. But it’s increased voltage — not amperage — that delivers the faster charge.
Overall, the Galaxy S7 is a sweet phone, and its battery capabilities let users have their cake and eat it too.
Update: The newly released Galaxy S7 Active ups the ante on battery life even further, with 4,000 mAh in the tank. For more on the S7 Active, Marques Brownlee can give you a tour:
