There are, of course, various exceptions. In YouTube, for example, the phone remains at Hz when you're playing back 24fps videos, but it does drop to 60Hz for 30fps and 60fps content. We gather the Hz for 24fps behavior has something to do with avoiding pulldown for 24fps content in 60Hz not that anyone's noticed an issue with that up until now , but why not 48Hz if the display supports it?
Funnily enough, if viewing YouTube in a browser, the S21 will, indeed, switch to 48Hz. Could it be a YouTube app limitation? As far as games go, the S21 will unlock its high refresh rate for many popular titles that are known to go above 60fps. Other refresh rate peculiarities include a 60Hz cap on the camera viewfinder - perhaps related to the sensor readout. There is also a 60Hz cap in Google Maps - perhaps Google's own doing there.
Though, on second thought, there could be potential burn-in related concerns that mandate refreshing those pixels every now and then. The Galaxy S21 draws power from a 4,mAh battery, the same capacity as last year's phone. With the same screen, a newer, more efficient chipset, and an adaptive refresh rate display, logic dictates that the S21 will have at least a little bit better endurance. Turns out, it's a lot better.
As for web browsing, the S21 stands at virtually identical 11 hours h this year, on the S Video playback returned dramatically improved numbers - we clocked 15 hours of offline video playback. We carried out these tests in the Adaptive refresh rate mode, while constantly monitoring the current refresh rate thanks to Android 11's built-in tool. Our web browsing script refreshes pages every 10s and every refresh triggered a spike in the refresh rate to Hz which then dropped back down to 60Hz s later.
We reckon that's a behavior fairly representative of real-world use - you swipe on the screen, refresh rate shoots to Hz, you then read for a bit, it goes down. As for the video playback, the phone maintained a Hz refresh rate throughout the test - since it does actually do that when playing back 24fps content, we think that this, too, is a good representation of real-life usage.
With all that in mind, we arrive at an overall Endurance rating of 93h for the Samsung Galaxy S21 5G. Our battery tests were automated thanks to SmartViser , using its viSerDevice app. The endurance rating above denotes how long a single battery charge will last you if you use the Samsung Galaxy S21 5G for an hour each of telephony, web browsing, and video playback daily.
We've established this usage pattern so that our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritty. You can 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.
On to a painful subject - charging. The Galaxy S21 comes with no charger in the box, so you need to supply your own. It's not that anyone would miss it - the 45W adapter wasn't meaningfully faster than the bundled 25W one, and you needed to buy it separately. Okay, that last argument falls a little flat now that the 25W one comes at an extra price too. We'll need to do our own testing to be sure. But taken as a whole, Samsung's numbers suggest battery life might not be totally on par with last year's phones.
On paper, the Galaxy S8 has the same battery capacity as the Galaxy S7, and the larger Galaxy S8 Plus only has a slightly smaller battery than the Galaxy S7 Edge -- but the new phones have much larger screens, which can increase drain. However, both phones also have a more efficient 10nm processor: the Qualcomm Snapdragon , or -- depending on your country and carrier -- a new Samsung Exynos.
Qualcomm claims its chip will use up to 25 percent less power than last gen, which may offset the battery life impact of Samsung's screens. There could be a huge silver lining even if battery life dips: Samsung claims the Galaxy S8's battery won't wear out as quickly as the Galaxy S7. It sure sounds like Samsung might fix the biggest reason I decided to ditch the brand : when my personal Galaxy S7's battery life dropped like a stone after the first year.
Personally, I'd rather have 12 hours of web browsing today and 11 hours tomorrow, instead of 13 and Not all phones are created equal though, so to mark a decade of Galaxy S devices we thought it would be a fun idea to rank each generation in order from worst to best. We tried to balance the critical and commercial reception with the actual importance of each phone s , the features and specs on offer, and our own gut feelings.

For a more detailed look at the history of Galaxy S phones, be sure to read our retrospective here. It also saw Samsung match Apple in terms of pricing strategy, having generally been cheaper than the iPhone until this point.
But the Galaxy S6 takes the wooden spoon in our rankings because it cut or compromised so many features seen on the Galaxy S5 in order to achieve this design. That meant no IP rating, no removable battery, no microSD support, and a much smaller battery. The phone that started it all, the Samsung Galaxy S or Galaxy S1 seems laughable now when you check out the specs. But this was pretty much as good as it got in the early days of Android , and it really was early. The biggest downsides were the uninspired design, gaudy software, and lack of a camera flash.
Between the early nature of Android at the time and a general lack of polish, the Samsung Galaxy S1 fell just shy of greatness. But it also felt like the moment where Samsung jumped the shark. Do you really need page scrolling via a head tilt?
Or the ability to create a 5. This is also the first Samsung Galaxy S series that completely ditched the headphone jack. Still, the price drop combined with an upgraded Ultra model seems to have resulted in huge initial sales growth in the US. The Galaxy S9 was essentially the Galaxy S8. It featured a similar glass design to the Galaxy S8, with lots of internal specs staying the same too.
