Samsung Galaxy S7 Battery Life Review

Let us take a look at common tasks on Video playback and Wi Fi browsing which will coupled with an extrapolation of expected battery’s life. Now it’s the time for putting these two phones on testing.


To kick off the testing, we charged both the handset fully and after battery was full we removed the charger and started to ran our Wi Fi browsing test tool until the battery was fully drained to nil. Once the battery was empty we then again recharged the both phones but only up to 2 to 10 percent. And then noted and recorded the Time on Android Operating System screen.

Video playback results are as follows:

In the test we found that both the versions of the Galaxy S7 struggled in the Wi Fi browsing test and they excelled in the video playback test. On the other hand the version of Snapdragon beat both the Nexus 6P and Galaxy Note 5 with the average battery life of 11 hours and 52 minutes.

But it is to be noted that the Exynos S7 went a whole lot further around at 15 hours and 11 minutes.Samsung Galaxy S7


Our final and third test involved the test about longevity of both the handset which will work as an indicator for the maximum standby life.

Both of the smartphones were charged fully and WiFi was turned on with the same set of syncing data apps and there were total notifications of 11 apps. Then the remaining battery life was measured exactly after the 24 hours and then this data was used to extrapolate the total potential of battery life.Standby Time of Galaxy Note 5 and Nexus 6p

After the comparison, the first thing to be noticed is that the Galaxy Note 5 offers considerbly a lower potential standby time than the other 3 handsets that are Exynos S7, Nexus 6P and Snapdragon S7 and the reason is very simple that at the time of testing it was only running on the Lollipop OS and it didn’t provide the benefit of Doze Mode on Marshmallow.

For the running Marshmallow and with the Samsung it rather seems to have done a good job with the 3,000mAh unit within the Galaxy S7, which is smaller than the 3,450mAh unit that will power the Nexus 6P.

The both of the versions have exceeded the 9 days 2 hours as offered by the Google’s flagship with the Snapdragon version of 9 days and 10 hours and for Exynos model of 10 days and 2 hours.Video Playback


Testing the smartphones under these conditions is not always indicative of day-to day usage.

Also the variables such as usage on other apps and network coverage and more can all also impact the actual battery life which is offered by a smartphone.

You can expect the one day usage by either of the two models, which will offer you a full charge screen time between 4 to 6 hours.

But do remember that the actual battery life may vary and the maximum I got from either of the handset is about 6 hours and the minimum will be low as two and a half hours.

As with low to medium usage the standby time is mostly impressive. Heavy users may or should get the on time screen of around 4 hours and the light users should be able to use for about two days from a fully charged battery. On the other hand the unbranded model SM-G930F from Exynos seems to last between 10 to 20 % longer than its cousin i.e. Snapdragon.
