The OnePlus 3 is the typical bang-for-the-buck smartphone. It’s the total package that offers superb software, performance and design without going overboard financially. OnePlus has only been around for a while but the company has been consistent in producing quality handsets from the start, and the OnePlus 3 continues the tradition.

Meanwhile, the Samsung Galaxy S7 Edge is arguably the best mobile device available today. The South Korean tech titan’s current flagship is feature-packed and provides long-lasting performance in any and all settings. Let’s see how the OnePlus 3 stacks up against the Samsung Galaxy S7 Edge performance-wise in a battery review and comparison.

The Samsung Galaxy S7 Edge can provide about 74 hours of music play or 27 hours of phone calls thanks to its robust 3,600 mAh non-removable lithium-ion battery. A whole day of regular to heavy use can still leave about 25 percent to 35 percent in the tank. Thanks to Android Marshmallow’s Doze feature, the Galaxy S7 Edge only consumes roughly two percent of its battery when the handset is not used overnight.

The Galaxy S7 Edge has exceptional overall standby time, but laborious tasks like gaming can bring down the battery level rather fast. The Samsung flagship can reach 100 percent within an hour and a half of charging using the bundled power adapter. The S7 Edge also boasts of its wireless charging capabilities, which the OnePlus 3 doesn’t have.

The OnePlus 3, on the other hand, sports a 3,000 mAh non-removable lithium-ion cell, which is strangely less powerful than the OnePlus 2 battery, let alone the Galaxy S7 Edge. While the phone’s lasting power is acceptable for moderate usage, there’s still room for improvement. The OnePlus 3 battery typically drains within a day.

According to Trusted Reviews, the OnePlus 3 can be fully charged in just a short amount of time. Thanks to the Dash charger, the OnePlus 3 can go from zero to 95 percent in less than 60 minutes. It also prevents the phone from overheating despite its fast-charging efforts.

When TechRadar had the Samsung Galaxy S7 Edge and the OnePlus 3 undergo a battery endurance test using “Pokémon Go,” the Samsung flagship emerged as the clear cut winner. The two smartphones were left to drain away under the same gameplay settings: on full brightness, no other background apps running, on same Wi-Fi connection and with GPS turned on.

The OnePlus 3 had no life left after only three hours and six minutes of “Pokémon Go.” The Samsung Galaxy S7 Edge, meanwhile, still had four percent battery life to spare after five straight hours of gameplay.
