Samsung’s contemporary

Galaxy S21 collection is powered by the latest

Snapdragon 888 within the US which can not

beat Apple’s A14 in uncooked benchmarks, however has the thrilling benefit to ship with a completely built-in 5G modem, versus Apple’s tack-on modular answer that could be a battery hog. 

Consequently, Qualcomm boasts as much as 3 times efficiency per watt enchancment when in comparison with the Snapdragon 865 within the S20 and ditto for Samsung’s different S21 chipset, the

Exynos 2100. Add to those the decrease decision that the Galaxy S21 makes use of, and the adaptive refresh charge display know-how, and it is occasion time.

Samsung Galaxy S21 battery life take a look at

‘Power to final via your day,’ says Samsung, after which some


  • 4000mAh
  • 25W-45W wired charging
  • 15W wi-fi charging

Curiously sufficient, the S21 is the one one of many new trio for which Samsung talked about greater than a day of battery life, despite the fact that it has the smallest battery pack. Last yr, the Galaxy S20 obtained a superb rating with its display at 60Hz, as battery life reached 12 hours and 12 minutes throughout our testing process, however if you switched to 120Hz, the battery life took greater than a 30% hit right down to 7 hours and 45 minutes. 

Since the S21 has a extra up-to-date show know-how with adaptive refresh charge, and decrease display decision, it is going to clock in a minimum of thos hours, regardless of the extra highly effective chipsets however we are going to reveal the outcomes of our assessments later this week.

120Hz (searching take a look at) 60Hz (searching take a look at)
Galaxy S20 (4000mAh battery) 7 hours 45 minutes 12 hours 12 minutes
Galaxy S21 (4000mAh battery) 8+ hours (exp.) 12+ hours (exp.)


The battery unit of the S21, whose mannequin quantity is EB-BG991ABY, sound acquainted? It is definitely the 4000mAh EB-BG980ABY piece that’s discovered contained in the S20 as properly, so battery life needs to be about the identical, proper? Well, probably not, and this is why. 

Galaxy S21 vs Galaxy S20 battery life effectivity

The FHD (S21) vs QHD (S20) show

While the Galaxy S20 is supplied with an overkill 1440p decision on a relatively tall and slender 6.2″ display, Samsung went the smarter route this time round, and is launching the S21 with a 1080p panel. The decrease pixel density makes for a way more frugal panel, as there are 1MM+ much less pixels to mild up and handle with the graphics subsystem. Our personal battery assessments present that telephones with FHD screens carry out 20-30% higher by way of battery life than these with QHD or larger display resolutions once we common out for the battery capability distinction.

Tap the decrease band of that vary, and the S21 ought to outlast the S20 with two hours, hitting a tenner in our searching and scrolling battery take a look at, all different issues being equal. The level is they will not be equal, nonetheless.

The 5nm (S21) vs 7nm (S20) processor

Compared to the second-gen 7nm (7LPP) Snapdragon 865 processor within the S20, made within the TSMC foundry, the 5nm Snapdragon 888 is made utilizing Samsung’s new EUV course of. The indisputable fact that Qualcomm not solely switched nodes from 7nm to 5nm, but in addition the foundry itself , is a vote of confidence in Samsung’s Extreme UltraViolet (EUV) lithography.

According to Samsung, its 5nm EUV course of presents not solely a fifth smaller footprint of the chipset on the similar efficiency, but in addition about 20% smaller energy draw. Alternatively, telephone makers can select to achieve a ten% efficiency improve on the similar battery consumption. Given that cellular chipsets are already highly effective sufficient for something you might throw at them, and the brand new X1 cores are clocked on the similar 2.84GHz because the 865, Samsung is more likely to go together with the beneficiant energy consumption lower.

The built-in (S21) vs standalone (S20) 5G connectivity

The 7nm vs 5nm course of alone will not make a big additional distinction in battery life between the 2 telephones, although, as the principle energy draw comes from the show. The telephones’ 5G connectivity battery draw, nonetheless, will, as sustaining a hyperlink to the 5G community is a battery hog. Why? Well, first off, earlier than Snapdragon 888, solely Huawei had built-in 5G system-on-a-chip (SoC) for flagship telephones. Qualcomm made do with chipsets just like the 765 within the Pixel 5 or LG Velvet, which, albeit having the 5G modem as an integral a part of the chipset, are a far cry from its 8-series by way of efficiency.

With Snapdragon 888, nonetheless, Qualcomm managed to lastly do what it does finest – pair the quickest ARM Cortex cores accessible with a brand new highly effective Adreno 650 graphics AND fuse them with the X60 5G modem that can also be made on the 5nm course of. That alone quantities for a big drop in energy consumption when linked to a cell tower however Korean media simply reported that there can even be enhancements within the 5G antenna {hardware}.

Next-gen 5G antenna isolation

Fast 5G networks like Verizon’s Ultrawide Band (UWB) mmWave can carry a variety of information directly and quick, however have very unhealthy sign penetration that forces telephone makers to slap a bunch of additional antennas throughout their handsets simply in order that the sign can go via your grip alone.

Samsung, nonetheless, is utilizing the subsequent technology of low permittivity polyimide (PI) movies for the 5G antennas within the Galaxy S21 telephones. This means simpler sign passthrough, and fewer toll on the battery. 

Taken individually, all these energy draw enhancements, excluding the decrease pixel density, might not quantity to a lot, however as an entire, present a wholesome enhance to the Galaxy S21 battery life from the identical 4000mAh battery capability.
