Top 3 battery settings to change after One UI 9.0 update

Samsung has started rolling out One UI 9.0 update and Galaxy users should look at optimizing their phone’s power settings to extend battery life.

Android 17-based One UI 9.0 update brings a refined interface and smoother animations, but learning how to manage the system’s power consumption is the key to getting through a heavy day without reaching for a charger.

Whether you want to stretch your daily screen-on time or protect the physical health of the battery over the next few years, the new settings menu has you covered.

Here are the top three battery settings you need to tweak right after updating to One UI 9.0:

1. Configure the New Battery Protection Modes

One UI 9 gives you much more granular control over your phone’s long-term battery health. Instead of a simple on/off toggle that limits charging to 85%, Samsung now offers three distinct tiers to prevent battery degradation over time.

Where to find it: Go to Settings > Battery > Battery protection

Choose between Basic (stops at 100% and waits until it drops to 95% to resume), Adaptive (pauses at 80% while you sleep and finishes charging right before you wake up), or Maximum (hard caps the charge at 80%).

2. Switch to the “Light” Performance Profile

Standard Power Saving mode is great for emergencies, but it disables your 120Hz refresh rate and limits background data. If you want to save battery without making your phone feel sluggish, the Light Performance Profile should be your pick.

Where to find it: Go to Settings > Device Care > Performance profile | Switch the profile from Standard to Light

3. Aggressively manage background usage limits

One UI 9 is excellent at managing background power usage, but manually moving unused apps into “Deep Sleep” guarantees they won’t sip power when you aren’t looking.

Where to find it: Go to Settings > Battery > Background usage limits

Tap on Deep sleeping apps, hit the + icon, and add any apps that you rarely use or don’t need real-time notifications from (like airline apps, fast food apps, or older games).
