Samsung Galaxy S7 Battery Life

By 02:18 Sun, 01 Aug 2021 Comments


We've been through it a lot - the Samsung Galaxy S5, as all Galaxy S's before it, had a user-replaceable battery, and the S6 didn't, which sucks. Not only that, it actually had a smaller battery than the model it replaced.

The first part of that tale doesn't seem likely to change, as design constraints have been forcing manufacturers to seal batteries inside devices, not just smartphones. Well, fine thing then, that Samsung actually fitted a higher power power pack inside the Galaxy S7 than it did in the S6. It is, in fact, the most juice a vanilla Galaxy S-series model has had - specialty editions like the S6 active and S6 edge+ don't count.


The Galaxy S7 has a 3,000mAh battery, which is the most that 5-inch (or thereabout) smartphones have these days, matched by the latest Xiaomi Mi 5. The current, and likely last of its kind, Sony Xperia Z5 packs 2,900mAh of juice, mated to a marginally larger 5.2-inch display.

The LG G5 has a 2,800mAh cell for an even larger 5.3" screen, while the outgoing G4 relies on the same 3,000mAh power to power a 5.5-inch display. Yes, both LG smartphones are bigger, but who's to blame if the company doesn't have a flagship offering close to the 5" mark? In their favor though, both models feature a removable battery. Now, LG does create the Nexus 5X, and that's a flagship of sorts with a 5.2-inch display and a 2,700mAh cell.

The iPhone 6s, on the other hand, has a lowly 1,715mAh battery to feed a 4.7-inch display.

It's what the Galaxy S7 does with its 3,000 milliamp hours that matters as we've seen plenty of impressive spec sheets that couldn't transfer into reasonable battery life. So, as usual, we carried out our array of battery tests, and while the summary can be found in the review, we'll acquire into a small bit more detail in these few paragraphs here.

The Galaxy S7 does very well, to put it simply. Starting with voice calls over a 3G network, the S7 can outlast all of the above (well, we can't be sure about the Mi 5 and G5 just yet). And even then, it's the Galaxy S6 that comes closest, not one of the competing brands. The Xperia Z5 follows, at a distance of almost 5 hours behind the S7. The iPhone 6s fares rather miserably in this respect with less than 10 hours of talk time on a charge.

Samsung's latest nearly hit the 15-hour imprint in video playback, a result the rest here can't even dream of coming close to. The S6 puts up a semblance of a fight, but is dead in about 12 hours, and the iPhone 6s can't create it to 11 hours. The 8-hour endurance of the Xperia Z5 is mediocre, but Nexus 5X with 6:23h is the real disappointment here.

It's just web browsing that left us wanting, and not becautilize the result is particularly bad, it's just not better than the S6, and better than the S6 is what it should have been. The S7 calls it quits after 9 and a half hours on the web over Wi-Fi, when its predecessor can stay online for an hour and a half longer.

We typically carry out the test with whatever proprietary browser there is pre-installed, and if the outcome is troubling, we repeat with Chrome to rule out any poor optimization from in-houtilize software engineers. So we did on the S7 (just in case, not that we doubt Samsung's team) and the result came out at a small over 10 hours - an insignificant incompatibility to warrant the Chome numbers making it to the score card.

All that said, the S7 still manages to outlast the LG G4 and the Nexus 5X, by an hour and an hour and a half respectively. The iPhone 6s shows impressive efficiency and despite the significantly smaller power manages a massive 3 hours more than the S7, and yet it's no match for the Xperia Z5's 14 and a half hours.

The numbers above add up to a combined endurance rating of 80 hours, still better than any of the other devices we mentioned. The Galaxy S6 and the Xperia Z5 both have a 73-hour endurance rating, for a shared second spot. No bronze will be awarded.


Oh, wait, Always On display. You see, our proprietary battery testing procedure includes a standby test, which is included in the formula for overall rating, but we don't post it on the scorecard. Standby is rarely the dominant contributor to power consumption, with large displays being a far heavier burden on the battery.

Well, with the Always On display enabled a part of that display is being lit up, and that inevitably has a detrimental effect on battery life. Samsung says that it runs in the ballpark of 1% battery drain per hour, and our findings seem to corroborate that.

A clock and background image was our choice (those pictured above, actually) - sort of a middle ground in terms is content volume being displayed. With AOD on, overall rating takes a huge hit and drops to 49 hours. Whether the trade-off is worth it is largely up to you.
