The Samsung Galaxy S7 Edge is arguably the best all-around mobile phone available, thanks to its powerful specs and outstanding battery. The iPhone 7 Plus, on the other hand, is the greatest handset Apple has made so far, and it trumps its predecessors in all aspects. Let’s see which flagship offers the utmost convenience to users when it comes to battery longevity and charging speed.

The Samsung Galaxy S7 Edge sports a non-removable 3,600 mAh lithium-ion battery that delivers 74 hours of music play and 27 hours of 3G phone calls. The handset can last a whole day of moderate to heavy use with about 25 percent to 35 percent battery life to spare. While the Galaxy S7 Edge drops cell power pretty fast during intensive tasks like heavy gaming, it makes up for it with outstanding standby time.

When left unplugged overnight, the S7 Edge only eats up about 2 percent of its battery with the aid of Android Marshmallow’s Doze feature. The Samsung flagship only takes about 90 minutes to reach the 100 percent level using the packaged power adapter. The Galaxy S7 Edge can also be charged wirelessly.

The iPhone 7 Plus also furnishes a non-removable lithium-ion battery, although it packs in less power compared to the Galaxy S7 Edge at 2,900 mAh. It provides up to 21 hours of talk time and 60 hours of music play. The Apple smartphone can reportedly endure a couple days of moderate use.

The iPhone 7 Plus also equips the latest energy-efficient A10 Fusion chip, which helps extend battery life. No fast charging feature is available on the iPhone 7 Plus, so users have to wait for a prolonged amount of time before the battery reaches 100 percent from zero.

When SuperSaf put the Galaxy S7 Edge and the iPhone 7 Plus to a battery charging speed test, the Apple handset was completely left behind. After an hour of charging, the Samsung Galaxy S7 Edge had 85 percent battery life while the iPhone 7 Plus only had 36 percent. Just over 29 minutes later, the S7 Edge was fully charged. The iPhone 7 Plus, meanwhile, took almost three and a half hours to reach 100 percent. Both phones started charging at one percent while on flight mode.
