How to Set Charging Limit in One UI 7 on Samsung Galaxy Phones

You may have heard an article or came across a video mentioning that charging your phone to 100% can degrade the battery faster. This is in fact true, and it is recommended to only charge your device to 80%. However, doing this manually can be a chore. This is why Samsung includes the ability to set a charging limit in One UI that can help protect your Galaxy phone’s battery.

How to Set Charging Limit in One UI on a Samsung Phone

With the Battery protection, you can restrict charging to a certain percentage only. Once the device reaches that level, it will pause charging till it drops below that level. Here’s how you can set up charging limit on One UI 7 and later.

1. Open the Settings app, and go to the Battery option.
2. Here, tap on Battery protection.
3. On the next screen, turn on the Battery protection toggle at the top.
4. You’ll see three options below. To set your preferred charging limit, select Maximum.
5. Now, you can drag the slider at the bottom to set a desired charging limit between 80-95%.

Note: On older One UI versions, you can only set the charging limit to Adaptive. This will stop your phone from charging past 80%.

What Happens When You Set a Charging Limit?

By turning on battery protection and setting a charging limit, your phone will only charge up to that level. Let’s assume the limit is 80%. So when the phone reaches 80% charge, it will cut off charging, preventing it from going beyond the set limit. A “Charging stopped to protect battery” message will appear on the lock screen and a shield icon in the battery indicator at the top.

However, if it goes below this, then it will start charging again. On devices running One UI 7 or above, you can set the limit between 80% and 95%. This can come in handy if you know you’ll be out for too long and won’t be able to charge the device later, but you don’t want your battery to be damaged in the long run.

How Charging Limit Increases the Battery’s Longevity?

To understand how limiting charging capacity helps with battery longevity, we need to understand what is a charge cycle and how it takes a toll on the battery. When a phone is charged to 100% and used till it reaches zero, that is considered one complete charge cycle. However, once the battery goes through this cycle, it loses some of its capacity in the process.

That’s not all, charging the device to full and then draining it all the way also stresses the battery. This coupled with heat produced when charging wirelessly or when connected to a fast charger further degrades the battery. So the phone loses its original capacity, which you will notice over the years. It won’t last as long as it once used to.

This is why charging the phone to 80-85% is considered a soft spot. It puts minimal stress on the battery allowing it to last longer. Yes, you lose some percentage in the process, but your phone will retain its original capacity over a long time. Among recent updates, Apple added the ability to set charging limit on an iPhone. So has OnePlus and some other phone makers.

I can vouch that this feature works, as I have limited charging of my Samsung Galaxy M52 since day 1. Two and a half years later, it still lasts almost as long as it used to. With that said, I hope you found this guide useful, and do reach out to us if you have any concerns in the comments.
