14 February 2021
After looking into the performance of the two chipsets, we decided to move on to some differential battery comparisons, as well.

Anonymous, 15 Feb 2021Exynos at any S21 model slow compare with Snapdragon versionNot that, the trash claim about exynos slowing down over time compared to sd magically being as fast as day one.

    sohail shafayat, 15 Feb 2021you buy 2 phones,one on SD8XX and one on Exynos 9XX, now compareSo you were spouting bs again? Good to know.

      He asked you about proof that they are getting slower over time, not that they are slower compared to the SD version.

        Mediatek sux, 15 Feb 2021Huh? Proof please.you buy 2 phones,one on SD8XX and one on Exynos 9XX, now compare

              I got mine replaced. It had 3-4 hours SOT and very bad camera output in low light indoors with a bunch of noise and a yellowish hue.
              The new one I got works totally different - the camera is miles ahead and the SOT after two full charges is well over 6 hours with 20% battery left with Full Resolution and adaptive refresh rate.

                Well silly comment. A battery losers performance and processor never does unless the software logarithm changes and does not use the full potential of the processor thus making the phone slow in response time.

Samsung only has a 7 day replacement policy in India and doesn't think 4-5 hours SOT is bad.

                      4 hours SOT is the norm for S21 Ultra in India.

                        Exynos 2100 no way near as good snapdragon, give it year then go back to both chips you will see exynos chip always drop in performance compared to the snapdragon.

If you get faulty device, just get it replaced. Samsung is already giving free home service. 4 hours screen on time is ridiculous from a 5000mah 5nm device

I have used a Samsung Note FE with Exynos 8890 and I can tell you it slowed down although for most basic apps it was not that noticeable. Google Play took long to load at Android 8, which was faster at Android 7 (forgot the name of the UI). Also early versions of Android 8 appeared to have the multitouch bug which was annoying.

Both the devices never got slower. The trick to keeping every smartphone fast is.. deleting unused apps, unnecessary photos and cache. But the most important thing is restarting the phone every other night. Still the iphone lasted double as much as s6 edge.. but still I enjoyed using the Samsung more.

                                  Here's a video proof. Maybe a particular section of phones needs further updates to optimise the battery, or it might be a common bug with a particular app.

                                    From all the tests I've seen so far battery life is equal sometimes Exynos takes lead sometimes SD depending on tasks and as for the sustain performance Snapdragon do little bit better but Exynos version is more consistent overall I would say this year's Exynos is a huge upgrade over 990 apart from GPU department 2100 is as good as 888 if not better

                                      I can't imagine spending $1600 on the phone and not use it to its full potential to save battery.

                                      I wished the phone gave an SOT of 7-8 hours with heavy usage.
                                      And mind you, my heavy usage does not include video recording and gaming.

                                        Hello Life, 14 Feb 2021So it should. As Variable refresh rate can save battery.. s... moreWell, that's exactly the problem. Most of the Indian users are complaining about getting around 4 hours SOT,and that's bad.

                                        Anything less than 7 hours SOT on the S21 Ultra with average usage of web browsing, watching YouTube, using social media, and taking photos is not acceptable.
