Samsung Deutschland's battery test video has shown that, when compared five other phones with Samsung's Galaxy S7 and Galaxy 7 Edge flagships, there is no competition.

Mashable reports that this year's test has shown that the Samsung Galaxy S7 and S7 Edge have the best battery life, lasting for 10 hours and 59 minutes and 10 hours 30 minutes respectively. The Samsung flagship phones have been tested against the iPhone 6S, HTC 10, Sony Xperia X, Huawei P9 and LG G5.

In the video presenting the test, we can see the phones' batteries start dying sometime around the 6:30 hour mark. The first phone to have its battery discharged was the LG G5. Beside the winners S7 and S7 Edge, the battery in the iPhone 6S lasted 8 hours and 13 minutes.

The video presenting the test shows that Samsung smartphones are clear winners, even if the test has been organized by the South Korean company itself. However, according to Samsung, the mobile devices were tested on "equal terms."

The number of battery charge cycles each individual device has had and the exact settings used by Samsung during the test are not known. Other smartphone manufacturers have done their own internal testing as well.

According to Android Authority, smartphone manufacturers used to compare their own phones with phones from competitors so they can make bold claims at press conferences. These kinds of claims should always be taken with a grain of salt, however, since they are not always 100 percent accurate.

It is true that there are many ways to manipulate data to come out on top of these battery tests. Samsung's battery test might been no different, but tech experts tend to agree that the South Korean company's mobile devices have really good battery life.

Certainly, the S7 and S7 Edge batteries are among the best smartphone batteries on the market. Just do not expect your Galaxy S7 battery to last for 10 hours and 59 minutes as seen in the test video.
