Samsung Galaxy S7 Edge Battery Life (Exynos And Snapdragon)

By 06:21 Sun, 01 Aug 2021 Comments


We published our in-depth review of the Samsung Galaxy S7 edge earlier this week, and it was based on the Exynos version of the smartphone. We later got our hands on a Snapdragon version so we got a chance to compare the two in benchmarks, and now in battery endurance.


No matter the chipset, battery power of the Galaxy S7 edge is fixed at 3,600mAh - a generous amount. It is also a substantial increase over the S6 edge's 2,600mAh, not to mention the S6 edge+, which has a 3,000mAh power pack and a larger 5.7-inch display. In light of that, even die-hard removable battery supporters like us are willing to let it slide that the S7 edge's cell is sealed.

And that's even before we acquire to the fact that it charges very quickly, even if the S7 edge only supports Qualcomm's QuickCharge 2.0 standard and not the latest version 3.0. Samsung promises 0 to 100% in 100min for the S7 edge, and it's even more impressive just how rapidly those percentages climb from flat to 70% where charge speed starts to taper off.

Much like the company's last-year flagships, the Galaxy S7 edge is also capable of wireless charging with pads compliant with both Qi and PMA. Samsung will also sell you a quick wireless charging pad, which can fill up the battery nearly as quick as a cable will.

After we tested both versions, the summary goes like this. Number one - the Exynos-version is overall more efficient and outlasts the Snapdragon variant by a few hours in all three major tests and in Endurance rating. Number two - both are as good, or better than last year's S6 edge and S6 edge+.

Moving to the individual tests, the Galaxy S7 edge is fine for about 24:30 hours or 22:30 hours of 3G voice calls, Exynos 8890 and Snapdragon 820 respectively. Difference aside, both perform noticeably better than the competition: Nexus 6P comes closest (20:50h), but the LG V10 (16:40h) and iPhone 6s Plus (15:51h) will have died long before either S7 edge pops up a warning.

It would be an understatement to say that the Galaxy S7 edge excels at video playback longevity, especially the Exynos version. With its 20:08h result, it stands at the all-time second spot among devices we've tested, behind the Gioniee Marathon M5 (monstrous 6,020mAh battery, midrange hardware).

The Snapdragon S7 edge is no slouch either when it comes to watching videos and calls it a day after almost 17 hours - yes, impressive, but still 3 hours less. Then again, the iPhone 6s Plus throws in the towel another 3 hours earlier (13:57h). The Nexus 6P (9:59) will need two full charges to match the Exynos S7 edge, and you better have two spare batteries for the V10 (7:30) if you're looking to haged up with the edges.

In web browsing we have the Exynos Galaxy S7 edge leading this improvised pack with its 13:32h result, but here the Snapdragon version (10:09h) doesn't have what it takes to claim silver - it's the iPhone6s Plus for a change (11:51h). The Nexus 6P and LG V10 are in their usual unimpressive form and in this test hover around the 8:30 mark.

The Always On display feature was always going to be a battery drainer, no two ways about it. Samsung's claim that it would cost you 1% per hour seems about correct and it does leave a huge impact on the overall endurance rating. That's becautilize our proprietary score also includes a standby battery draw test, which we carried out with the AOD off and then once again with AOD on. These results are not featured in our test scorecard but are calculated in the total rating.


The Galaxy S7 edge (E8890) did splendidly with an Endurance rating of 98 hours - that's the amount of time the S7 edge would last on a single charge if you utilize it for an hour of 3G calls, an hour of web browsing, and an hour of video playback each day. Under the same utilize scenario, the Galaxy S7 edge (S820) gets an 87h Endurance rating.

A drop by about 30% in the rating follows if you turn on the Always on display Finally, if you want to utilize the Edge feeds, which require the classy screen to haged the capacitive sensors on, you will lose in the whereabouts of additional 7 hours.

However, and that's really important, the detrimental effect of all these additional features will be of much less significance the more you actively utilize your phone. Playing games, watching videos, surfing the web - any actual utilize that has the display on and the processor ticking at anything but idle will deplete the battery much faster than any always on clock or calendar ever can.







The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
