How to turn on “Light” Performance Mode on Galaxy S23
The Galaxy S23 series has some pretty good battery life this year. That’s partly thanks to the S23 and S23 Plus getting larger batteries (200mAh larger on each), and all three models using the Snapdragon 8 Gen 2 for Galaxy chipset. Which is manufactured by TSMC. TSMC has proven that it can really improve battery life with these chipsets, as we saw on the Snapdragon 8+ Gen 1 last year. Now, what about when you need a bit more juice? Well, Samsung has built-in a mode that can help with that, and it doesn’t really limit your phone.
Many smartphones (if not all) have some sort of battery saver mode. This is generally used when your phone gets really low, and will turn off some features, like the always-on display, lower brightness and such, to last even longer. However, Samsung’s Light mode is not that. Instead, it will slow down the processor speed a bit – Samsung does not disclose the clockspeed while in Light mode. That won’t affect how you use your phone. Since the Snapdragon 8 Gen 2 for Galaxy does run at up to 3.36Ghz, that’s not really needed for most smartphone things. And even the slower performance cores run at 2.8GHz, which is also faster than you really need. So by slowing it down, Samsung is able to improve battery life due to the amount of heat that the phone would produce, but also the power needed by the processor.
This is in addition to the ability to turn down the screen resolution (which is FHD+ by default on all models, though only the Ultra does QHD+), and adjusting the frame-rate. Which is 120Hz on all models, and it can be pushed down to cap at 60Hz. So there’s quite a few things you can do to improve battery life on the Galaxy S23 this year.
What is the Light performance mode?
In simple terms, Light performance mode is a battery saver mode that you can actually leave on all the time without disabling features of your phone. Here’s how Samsung explains it:
Light mode is a function that improves heat generation and battery consumption by changing the processing speed to partially adjust it to improve battery consumption. When operating in light mode, the device can use less performance power compared to normal mode with no impact to internet surfing, social media, phone calls or video playback.
Since it is really only slowing the clock speed of the processor (which is already overclocked, thanks to it using a Snapdragon 8 Gen 2 for Galaxy chipset), it’s not really going to affect the performance of your phone. Unless you’re using some resource intensive apps. Keep in mind that this does not affect gaming at all. So you can still get the full experience of gaming at 120fps on the Galaxy S23, even while using Light Mode.
How to enable the Light performance mode on Galaxy S23
First off, head into the Settings.
Tap on Battery and Device Care.
Next, tap on the Battery section.
From there, scroll down and find More Battery Settings, and tap on it.
On this next screen, you’ll find an option for “Performance Profile”. Tap on that.
Here, you will see two options: Standard and Light. Here’s a brief explanation of the two options:
- Standard: Provides the recommended balance between processing speed, battery life and cooling efficiency.
- Light: Prioritizes battery life and cooling efficiency over processing speed.
Choose Light, and now you’re all set.
How does this affect day-to-day usage?
It doesn’t really affect day-to-day usage, as it is really just slowing the clockspeed of the processor a bit. For most people you won’t really notice a difference here. Unless you’re opening some intensive apps like Snapchat, YouTube, and others. Though that’s more resource intensive due to the video aspect, and not so much on the processor.
Now what about battery life? How much does it improve it? Well, that’s hard to test, since no two days are the same on battery, but you can get a good 2-3 hours of screen on time on top of the almost 10 hours we normally get on the Galaxy S23 Plus and Ultra (we have not gotten our hands on the regular S23 yet). So it’s a good idea to check this out and see how it works out for you.
