10 Galaxy S25 Tips That Actually Work on One UI 8.5

The Galaxy S25 tips that make the biggest daily difference are small settings changes: set up the Now bar, remap the side button, cap charging at 80%, and learn Circle to Search and Audio eraser. Every tip below works on the S25, S25+ and S25 Ultra running One UI 8.5, the current stable release, and each one includes the exact settings path.

A quick note on software first. Samsung pushed One UI 8.5 to the S25 series in the US on May 11, 2026, and opened the One UI 9 beta (based on Android 17) for the S25 in September 2026. Menu names can shift slightly between versions, so if a path below doesn't match, use the search bar at the top of Settings.

Lock screen and button tips

1. Set up the Now bar and Now brief

The Now bar is the strip at the bottom of the lock screen that shows live activity: a timer, the song that's playing, a recording, sports scores or Maps directions. Now brief is the morning and evening summary of weather, calendar events and reminders. Out of the box, both show less than they could.

Following Samsung's setup steps, go to Settings > Lock screen and AOD > Now bar, tap View more, and switch on the categories you want. Then open Settings > Galaxy AI > Now brief and choose what it includes (events and tasks, travel, health, news). The same screen has a switch that lets you read the full brief straight from the lock screen. You need a screen lock enabled for the Now bar to appear.

2. Remap the side button

By default, pressing and holding the side button opens Gemini, and a double press opens the camera. Both can be changed in Settings > Advanced features > Side button. Double press can launch Samsung Wallet, the flashlight, a voice recording, or a specific routine such as Sleep. If you prefer the old behavior, set Long press to the power-off menu.

If you keep Gemini on the long press, you can still turn the phone off by pressing and holding the side button and Volume Down together, or from the Quick panel.

Galaxy AI tips worth using every day

3. Use Circle to Search instead of screenshots

Touch and hold the Home button (or the navigation handle with gestures), then circle or tap anything on screen: a pair of shoes in an Instagram post, a landmark in a video, a word in another language. Results open in a panel without leaving the app. If text is detected, tap Select text and then Translate for an instant translation. It is on by default; the switch lives in Settings > Display > Navigation bar.

4. Clean up noisy video with Audio eraser

Audio eraser sorts the sound in a video into categories (voices, music, noise, crowd, nature) and lets you turn down the ones you don't want. Open a video in Gallery, tap the pencil icon, then the speaker icon, then Audio eraser. Use "Hear original" to compare before you save a copy. It also works on call recordings, Voice Recorder files and Samsung Notes recordings, where it lowers background noise and lifts voices. Very short sounds, like a single car horn, may not be detected.

5. Translate phone calls live

Live translate turns a phone call between two languages into on-screen text and spoken translation. Turn it on in Settings > Galaxy AI > Call assist > Live translate and download the languages you need. During a call, tap Call assist and then Live translate. You can also enable it for WhatsApp, Messenger, Signal, Telegram, Google Meet and other apps under "Live translate in other apps." Samsung's advice: only one person on the call should use it at a time.

6. Get transcripts and captions for calls

Two settings in the Phone app make calls easier to follow. Call captions (Phone app > More options > Settings > Call captions) shows live text of what the other person says, useful in a loud room. Transcript assist (Phone app > More options > Settings > Record calls > Transcript assist) turns recorded calls into text with a summary, so you can find the address or reference number someone read out.

Battery and automation tips

7. Cap charging at 80% to protect the battery

Samsung built Battery protection to cut the hours your battery spends sitting full. Open Settings > Battery > Battery protection, turn it on, and pick one of three modes:

Mode	What it does	Best for
Basic	Stops at 100%, resumes charging at 95%	People who need every bit of charge
Adaptive	Holds at 80% while you sleep, finishes before you usually wake	Regular overnight chargers
Maximum	Stops at 80%	Anyone who ends the day with charge left

Adaptive learns your sleep pattern, so it works poorly if your schedule changes a lot. If you need a full charge for a long travel day, switch protection off the night before and back on afterwards.

8. Build a routine in Modes and Routines

Routines run settings changes for you based on a trigger. Open Settings > Modes and Routines, go to the Routines tab, tap the plus sign, then set an "If" (arriving at work, a time of day, connecting to car Bluetooth) and a "Then" (mute notification sounds, turn on Wi-Fi, lower brightness). Samsung's own examples are muting notifications when you arrive at work and dimming the screen at bedtime. Modes, such as Stay focused, bundle Do not disturb and app limits into one switch.

Multitasking and maintenance tips

9. Open two apps with a swipe

The S25 can run apps in split screen or in a floating pop-up window, and gestures make it fast. Go to Settings > Advanced features > Multi window and turn on "Swipe for split screen" and "Swipe for pop-up view." Now swipe up from the bottom with two fingers to split the screen, or swipe in from a top corner with one finger to shrink the current app into a pop-up. In split screen, the three-dot menu between windows can save the pair as an app pair icon on your home screen, handy for Maps plus Messages or Notes plus a browser.

10. Keep the software current and check what it added

Samsung's updates bring real features to the S25, not just security patches. One UI 8.5 added a redesigned Quick panel you can rearrange, more lock screen options, and upgrades to DeX, Clock and Battery settings. Check Settings > Software update > Download and install once a month, and read the change log after each install. The S25 series is covered by Samsung's seven-year update policy, so this phone will keep getting new tricks for years.

Which case works best with these S25 tips?

A few of these tips touch the case you choose. Battery protection and overnight wireless charging work best with a slim case like Lucca for the Galaxy S25, which works with Qi chargers as is.

If you want to carry cards, Capri for the S25 Ultra puts card slots on the back behind an RFID-blocking layer, and Florence for the S25+ adds a full wallet that slides off when you don't need it. Take the cards out before charging wirelessly. All S25 sizes are in our Samsung case collection, and our guide to cleaning a leather wallet case covers upkeep.

Thinking about upgrading instead? Our Galaxy S26 Ultra leather case guide covers what changed on the new Ultra, and iPhone vs Samsung compares both brands if you are weighing a switch.

FAQ

Does the Galaxy S25 get One UI 9?

Samsung opened a One UI 9 beta, based on Android 17, for the S25 series in September 2026. The stable release follows after beta testing. The S25 is covered by Samsung's seven-year OS and security update policy.

Why don't I see Live translate or Call captions?

Some Galaxy AI features depend on region, carrier and software version. Update to the latest One UI first, then search the feature name in Settings. If it's still missing, it may not be offered on your carrier's build yet.

Will an 80% charge limit make my S25 last longer?

That is the purpose Samsung gives for Battery protection: less time at full charge. On Maximum you give up about a fifth of each charge in exchange. If 80% gets you through the day, it is worth turning on.

Do S25 cases fit the S26?

No. The S26 models have different dimensions and camera layouts. Venito makes separate cases for each model in both series.

Start with tips 1, 2 and 7 today; they take five minutes and change how the phone behaves every day. Then put the S25 in a case that matches how you carry it, Lucca if you charge on a pad, Capri or Florence if you want cards with you.
