Samsung to bring the Light performance mode to Galaxy S23 phones for better battery life

03 November 2022
Light mode was recently added to the Galaxy Z 2022 foldables. It prioritizes battery life and running cool over absolute performance.

If you go way over it to squeeze out every point of performance, you'll sacrifice efficiency. I think if this caps X core to few hundred MHz below top clock, it should still give plenty of performance while significantly lower power draw and heat.

X core running at 2.5GHz instead of 2.8 or 3GHz should significantly improve efficiency. Hell, it might even work well at just 2GHz. Just not disabling it entirely. I don't think that would be great idea.

    walkman8, 03 Nov 2022You might as well buy some 200€ Xiaomi and call it a day People complain of battery, but praise the most power hungry features. Blame battery.
    People cant stay away from phones 5 min, blame battery for phone not lasting after 7 p.m.

    It is trade off. You get stuff, but have to sacrifice battery endurance.

      A710 and A510 are disaster, there is a reason why current flagship has bad standby time compare to midrange.

        Does xiaomi test the battery at 10W out of phone like Oppo to determinate its lifespam?

          They should just disable X core. It's just good for benchmarks but not in daily use because of it power consumption and heat.

            Funny and company like Xiaomi came with 210W charging and since Note 7 by Samsung and Apple battery gate problem no other phone or brand ever made had charging or battery issues.

            Something stinks here about Apple and Samsung.

              They needed to add this to the new One UI 5 update, The battery life for the s21 5G is really crappy.

                  I'm on light performance mode now. Can't really say it's much of difference. I'm going to switch back and see what happens.

                    yalim, 03 Nov 2022I saw some flip4 reviewers claim ending the day with 40% ba... moreI can confirm this. My daughter has a Flip 4 and its battery lasts longer than her previous Note 8.
                    I am running my Fold 4 since day one in light mode, and it feels at least as fast as the Fold 3, but the battery life is at least 50% better than Fold 3.
                    I tested a few minutes ago the difference in Geekbench: 1174/3797 vs. 1300/3816 (would it be already visible in Geekbench browser?). This means no difference in multi-core score, but just 10% in single-core score.
                    If this was any indication, it could mean that the S23 Ultra could last significantly longer than S22 Ultra when running in light mode.
                    This would be amazing! I am just wondering why Samsung did not emphasize the much better battery performance during the Fold 4/Flip 4 keynote.

                          Turning off 120Hz and 5G can easily improve battery more than 50%.

                            Oh, finally! Other manufacters should also add features like this. Perfomance is overkill since snapdragon 865 for a daily driver. Efficency IS the thing that most consumers need

                              Auto turn on performance mode or navigation with camera start, then turning it down, would be best.

                                I saw some flip4 reviewers claim ending the day with 40% battery remaining with 4-5 hours of screen on time using light mode.that is solid.

                                    Simple mode is not the same as this. It enables core functions and disables everything else. Light mode is like, related to CPU performance and not altering the functions of the phone

                                        They're just going to turn off the X core, or keep it on with freq around ~700 mhz-ish
