Samsung phones come with a performance profile that is buried inside Device Care, and switching it from Standard to Light is one of the easiest ways to make your battery last longer. I had been using my phone in the default setting for months without even considering flipping that toggle on my own phone until a few weeks ago. I flipped the switch out of curiosity, and the jump in screen-on time genuinely caught me off guard.
To be honest, there are a bunch of ways to make the battery last longer, but this one showed me a good result. If you have already tried some of the tricks that make Samsung phones run faster without touching this setting, you are leaving some charge on the table.
The setting is not out in the open
There are so many settings on a phone that are left untouched by millions because they believe that the company has already applied the best settings for optimal performance. But that is not the case. There are several features that are buried inside hidden menus that can not only make your phone run faster, but also give control back to you, the user.
Similarly, in our case, most people never explore the “More battery settings” menu. So it’s no surprise that this one flies under the radar. In every Samsung Galaxy phone, from budget A-series models to the Ultra flagships, the CPU is dialed up to Standard by default. That’s the profile that lets your phone feel instantly snappy the moment you unbox it.
But it also means your processor has to do more work and run hotter, pulling more power than it needs for basic tasks like texting, scrolling social media, or checking email. Without much ado, here is how you can find the performance profile option:
- Open the Settings menu.
- Scroll down and tap on Device care.
- Tap on Battery.
- Choose More battery settings.
- Select Performance profile and switch from Standard to Light.
That’s it. No restart required, no waiting period. The moment you switch profiles, the change is applied immediately, and Samsung even lets you drag a Performance profile shortcut into your Quick Settings panel. This eliminates the need to dig through multiple menus and lets you flip between profiles in a flash.
This happens when you flip the switch
It is a ceiling, not a cage
Light mode doesn’t disable the cores or lock your phone into some crippled state. As per Samsung, switching to Light profile slightly reduces your phone’s maximum processing speed, cuts down on heat, and squeezes out better efficiency.
This is all done while keeping things smooth for everyday use like browsing, messaging, and video playback. Think of it less as slowing your phone down and more as lowering the speed limit on a highway that you rarely drive at full throttle anyway. Your phone’s CPU can still function at its highest level when it needs to; it just does not chase the absolute peak clock speed for routine stuff.
That’s why the everyday phone-using experience barely changes. Apps still open fast, animations stay smooth, and you’re not going to notice a lag opening Chrome or replying to a text. Plus, if you aren’t a fan of animations doing their job at their own speed, you can speed them up in Developer Options.
My numbers were impressive
It feels significant when you are in Light mode for a longer period
I run a Samsung Galaxy S24 Ultra as my daily driver, and before switching from Standard to Light mode, my battery was averaging somewhere between 4.5 and 5 hours of screen-on time on a single charge. This isn’t bad, but it isn’t great either, given how much my phone is involved in my work.
After a week in Light mode with otherwise identical habits (using the same apps, same brightness, same notifications), I was consistently getting 6+ hours of screen-on time, and my battery still had juice left by the time I plugged in at night.
An extra hour or more of screen-on time does not sound dramatic until you realize that there is roughly a 20 to 25 percent improvement just from one toggle. You don’t need to close any app, set any aggressive background restrictions, and no dimming your display to the point where you cannot read it outdoors. Just a quieter CPU doing the same job with less waste.
Another thing to note is that switching to Light mode doesn’t affect the performance of heavy tasks. According to Samsung, the Light performance profile does not apply to gaming, so Game Booster and demanding titles still get full access to all cores when it matters.
Switch if you want more battery
If you are someone who wants the best battery performance from your phone, then you can switch to Light mode. But do note that just switching to Light mode won’t give you plenty of disposable battery life. You have to pair it up with the best battery-saving habits in order to have optimal battery performance. Do note that when you change the performance profile, you are also giving up on peak CPU performance. But that is something you might not be using anyway. If your Samsung Galaxy phone has this feature, there is very little reason not to try it for a few days and see the difference for yourself.
