Samsung has been releasing two versions of most of its premium smartphones lately – one with a Qualcomm chipset and one other one with its personal Exynos chips.
In the Galaxy S21 household, the chipsets in query are the Qualcomm Snapdragon 888 (US&China) and Samsung’s personal Exynos 2100, obtainable on each different market.
We already looked at how the two fashions evaluate in benchmarks and efficiency. Now it is time to see how they fare in battery life.
Here is a specs comparability between the chipsets powering the two fashions for reference:
|Chipset||Samsung Exynos 2100||Qualcomm Snapdragon 888|
|CPU||1x 2.9 GHz – Cortex-X1, 3x 2.8 GHz – Cortex-A78, 4x 2.2 GHz – Cortex-A55||1x 2.84 GHz – Kryo 680 Prime (Cortex-X1), 3x 2.42 GHz – Kryo 680 Gold (Cortex-A78), 4x 1.8 GHz – Kryo 680 Silver (Cortex-A55)|

The Exynos 2100 and Snapdragon 888 versions of the Samsung Galaxy S21 Ultra have almost similar battery endurance, exhibiting solely slight variance, hardly-noticeable in real-world use.
To be honest, this isn’t a completely new improvement. Other battery comparisons have already arrived at basically the similar conclusion. Mind you, this doesn’t essentially negate nor contradict the indisputable fact that at peak efficiency ranges the Exynos 2100 appears to outpace the Snapdragon 888 barely, however with the caveat of being about 26% much less environment friendly in a efficiency per watt race at its increased clock speeds. You can learn extra about that here.
The factor is that in real-world use, which our proprietary battery endurance check go well with tries to simulate, the cellphone isn’t actually pushed to the max. It’s a marathon, not a dash. Here are the new battery endurance outcomes as achieved by the Snapdragon 888 unit:
And listed below are our authentic ones, as printed in the full review of the Samsung Galaxy S21 Ultra, achieved on our authentic Exynos 2100 unit.
Our battery exams have been automated because of SmartViser, utilizing its viSerDevice app. The endurance score above denotes how lengthy a single battery cost will final you if you happen to use the Samsung Galaxy S21 Ultra 5G for an hour every of telephony, internet searching, and video playback each day. We’ve established this utilization sample in order that our battery outcomes are comparable throughout units in the commonest day-to-day duties. The battery testing procedure is described intimately in case you are excited by the nitty-gritty. You can try our full battery test table, the place you may see how all of the smartphones we have examined will evaluate beneath your individual typical use.
It is necessary to notice just a few issues about the testing methodology. The standby exams have been performed with the very best community sign, in the default state of the S21 Ultra, specifically with S-Pen on and AOD off.
The on-screen exams have been achieved in native 1440p decision with Adaptive refresh charge mode turned on, whereas consistently monitoring the precise refresh charge with Android 11’s built-in device.
Our internet searching script refreshes pages each 10s, and each refresh triggered a spike in the refresh charge to 120Hz, which then dropped again right down to 60Hz 1-2s later. We reckon that is a conduct pretty consultant of real-world use – you swipe on the display, refresh charge shoots to 120Hz, you then learn for a bit, it goes down.
As for the video playback, the cellphone maintained a 48Hz refresh charge all through the check – because it does really try this when enjoying again 24fps content material, we expect that this, too, is an effective illustration of real-life utilization.
For these of you hankering for extra particulars on the numbers themselves, we’ll begin with the two on-screen exams – internet searching and offline video playback. The internet searching result’s so shut between the two items that it’s simply inside the margin of error. The similar is usually true for the offline video playback outcome.
If we’re into nitpicking, it does appear that the Snapdragon 888 was slightly bit extra power-efficient in decoding our h.264 check clip. Really nor by a lot, although.
Standby instances between the two handsets have been almost similar, which is nice information since standby represents a giant chunk of what a handset sometimes does every day.
The solely notable distinction we noticed was in the name exams. Again, the distinction just isn’t enormous by any stretch of the creativeness, but it surely nonetheless caught our eye, particularly since the widespread consensus appears to be that Qualcomm’s X60 5G modem is a little more environment friendly than Samsung’s Exynos one. However, these claims are largely associated to effectivity in 5G community connectivity. Our name check is intentionally executed over a 3G or 4G connection to maintain it akin to older exams as a lot as attainable.
In any case, this yr the distinction between the Exynos 2100 and Snapdragon 888 versions of the Galaxy S21 Ultra appears to be almost intangible in sensible phrases. Hopefully, this marks the starting of a brand new equality pattern in camp Samsung for good.
