If you want to extend the lifespan of your battery then you must enable and use this useful feature on your Galaxy phone. So, in this guide, you’re going to learn how to enable protect battery on your Samsung phone running One UI 5.1 based on Android 13.
The Protect Battery feature’s purpose is to protect the battery. The battery will last longer if it is only charged to 85 percent of its whole capacity since battery life deteriorates with each full charging cycle—recharging the battery to 100 percent of its total capacity.
Samsung is finally providing consumers a method to get more out of their batteries by restricting the amount of charge the battery may receive each session. Protect Battery has long been available on Samsung tablets, but this is the first time we’ve seen it on a Galaxy smartphone.
Furthermore, with One UI 3.1.1 a new function named “Protect Battery” allows you to charge your phone up to 85 percent. “To maximize the longevity of your battery, limit the maximum charge to 85 percent,” Samsung says in the description.
The idea is to help extend the lifespan of your battery, as charging it to 100 percent every day will cause the lithium-ion cell to degrade faster. If you do this repeatedly over the course of a year, the battery will charge to 100 percent, but it will decrease faster, leaving you searching for a charger all of the time.

Step 1. Go to the Settings app.
Step 2. On the Settings page, tap Battery and device care.

Your Galaxy phone will no longer be able to charge beyond 85 percent, regardless of whether you use a cable or charge wirelessly. This function is also accessible to Galaxy Z Flip 3 owners, which is rather predictable.

Protect Battery on Samsung
That’s it. This is how you can enable the protect battery feature on your Samsung Galaxy phones to limit the charge to 85% in order to extend the lifespan of your battery. Similar battery protection features are also available from other smartphone makers. While Samsung’s feature will never allow a device’s battery to charge beyond 85 percent, Apple and OnePlus’s equivalent features will only limit charging levels to 80 percent before attempting to top up their batteries to 100 percent just before they’re unplugged to reduce the amount of time spent fully charged.
