The phone is lil lagging like switching bw apps and the refreshrate of screen is going down to 60 i can feel lag in screen. Anyone else feels the same or its just me?

My $40ish headphones sound so much better on my S25 than on my old Samsung A55. One of the noticable improvements is that on my A55, if I put the volume close to max, there begins this hissing sound when the music plays but on my S25, same song, same volume even to the max the hissing is gone! Other than that the quality is just better...how???

🛠️ Phase 1: On-Device Settings Optimization

Before running any scripts, prepare your phone with these baseline system settings.

Step 1: Factory Reset Your Phone (Optional, but Highly Recommended)

• Why it helps: Clearing out old residual files, leftover cache from system updates, and conflicting app configurations gives you a completely clean slate for maximum battery efficiency.
• How to do it: Settings ➔ General management ➔ Reset ➔ Factory data reset

Step 2: Set Up as New (Don't Restore Old Settings)

• Why it helps: Restoring backups from Smart Switch or Google Cloud often reinstalls corrupted cache files, hidden background daemons, and old battery-draining app configurations.
• How to do it: During initial device setup, select "Don't copy" / "Set up as new device" and manually download only the apps you actively use.

Step 3: Turn Off Always On Display (AOD)

• Why it helps: Keeps the screen controller completely asleep when the device is idle, saving roughly 1% to 1.5% battery per hour throughout the day.
• How to do it: Settings ➔ Lock screen and AOD ➔ Toggle Always On Display OFF

Step 4: Turn On Power Saving Mode (With Adaptive Refresh Rate Keep-Alive)

• Why it helps: Power Saving mode restricts background network sync, location checks, and background tasks. Leaving Adaptive Refresh Rate active gives you full 120Hz display smoothness while targeting background resource consumption.
• How to do it: Settings ➔ Device care ➔ Battery ➔ Power saving ➔ Uncheck Limit motion smoothness to Standard (keep Adaptive Hz enabled), then toggle Power saving ON.

Step 5: Enable Light Performance Mode

• Why it helps: Light mode optimizes processing speeds and thermals to prioritize battery life and cooling without causing noticeable lag in daily use or gaming.
• How to do it: Settings ➔ Device care ➔ Performance profile ➔ Select Light

Step 6: Disable Battery Optimization for Critical Apps

• Why it helps: Standard One UI battery optimization can interfere with essential background synchronization, leading to delayed push notifications or erratic app behavior.
• How to do it: Settings ➔ Apps ➔ Select your desired app ➔ Battery ➔ Set to Unrestricted

Step 7: Put Unused Apps into Deep Sleep

• Why it helps: Prevents apps you rarely open from starting background services, tracking location, or draining battery when you aren't using them.
• How to do it: Settings ➔ Device care ➔ Battery ➔ Background usage limits ➔ Toggle Put unused apps to sleep ON

Step 8: Disable Nearby Device Scanning

• Why it helps: Stops your S25's Bluetooth and Wi-Fi modems from continuously scanning for surrounding devices in the background 24/7.
• How to do it: Settings ➔ Connections ➔ More connection settings ➔ Toggle Nearby device scanning OFF

💻 Phase 2: Debloating Methods

Choose Method A (PC Scripts), Method B (Termux on Phone), or Method C (Canta + Shizuku GUI) depending on your setup.

Method A: For Windows & Linux Users

Requirements:

• Python 3 installed on your PC.
• Android SDK Platform Tools (ADB) installed and added to your system PATH.
• USB Debugging enabled on your phone (Settings ➔ Developer options ➔ USB debugging).

Instructions:

Step 1: Download or clone the ZIP from theTL3-GUIDE GitHub Repo.

Step 2: Connect your S25 to your PC via USB and authorize the ADB prompt on your phone screen.

Step 3: Open a command prompt or terminal inside the WINDOWS AND LINUX METHOD directory.

Step 4: Execute all 4 Python files sequentially:

Bash

python "disabling real time scaning.py"
python "Uninstalling Telemitry pkgs.py"
python "Restrict all non essential pkgs from runing in the background.py"
python "Restricting all third party apps from runing in the background.py"

Step 5: Restart your phone.

Method B: For Termux Users (No PC Needed)

Instructions:

Step 1: Install and open Termux.

Step 2: Copy and paste the following commands to clone the repo and run the scripts:

Bash

pkg update && pkg upgrade -y
pkg install git python -y
git clone https://github.com/tahalaghzal2012-dot/TL3-GUIDE.git
cd TL3-GUIDE/"TERMUX METHOD"
python "Disabling in real time Scaning.py"
python "Uninstailing Telemetry Apps.py"
python "Restricting all PKGS from working in the background.py"
python "Restricting all Third party apps from working in the background.py"

Step 3: Restart your phone.

Method C: For Canta + Shizuku Users (GUI / No PC Needed)

Requirements:

• Shizuku (Activated and permissions granted).
• Canta (Installed and authorized via Shizuku).
• JSON Viewer/Editor app (Recommended:JSON Forge on Google Play).

Instructions:

Step 1: Download the repository fromRuvomain-Protocol GitHub Repository.

Step 2: Open the following directory: Ruvomain-Protocole/Configs/S25+/.

Step 3: Select one of the JSON files (Recommended: Stable version).

Step 4: Open the file using your JSON viewer/editor app and copy all the text inside it.

Step 5: Open Canta (ensure it is activated via Shizuku with required permissions granted), then tap the 3 dots menu ➔ Presets ➔ Import presets ➔ Import presets from clipboard ➔ Apply.

Step 6: Restart your phone.

⚡ Phase 3: Advanced ADB System Tweaks

1. Aggressive Doze Timing Tweaks

Bash

adb shell settings put global device_idle_constants "inactive_to=30000,sensing_to=0,locating_to=0,location_accuracy=20,motion_inactive_to=0,idle_after_inactive_to=0,idle_pending_to=30000,max_idle_pending_to=60000,idle_pending_factor=2.0,idle_to=3600000,max_idle_to=21600000,idle_factor=2.0,min_time_to_alarm=60000"

• What it does: Forces Android to enter Deep Doze mode almost immediately after the screen turns off, significantly reducing overnight standby battery drain.

2. Limit Battery Saver Background Execution Duration

Bash

adb shell settings put global battery_saver_constants "background_max_duration=30000"

• What it does: Restricts background tasks from running longer than 30 seconds continuously when power saver features are active.

3. Optimize RAM Usage by Limiting Cached Processes

Bash

adb shell device_config put activity_manager max_cached_processes 24

• What it does: Caps system RAM cache to 24 active background processes, reducing CPU overhead and keeping thermals cool.

4. Enforce Strict App Background Execution Limits

Bash

adb shell settings put global app_restriction_enabled true

• What it does: Enforces strict system-level background execution rules on non-essential apps trying to wake up the CPU.

5. Enable Android Standby Buckets

Bash

adb shell settings put global app_standby_enabled 1

• What it does: Enables Android's built-in intelligent power management to categorize apps based on usage frequency and restrict inactive ones automatically.

📊 Results & Real-World Battery Proof

Here are my Screen-On Time (SOT) and battery stats before and after applying this optimization setup on my Galaxy S25:

🔴 Before Optimization:

• Screen-On Time (SOT):
• Battery Drain Profile: High background activity and thermal buildup during daily use.

Befor Optimisation (same usage)

🟢 After TL3 Optimization (100% to 0% Drain Test):

• Screen-On Time (SOT):
• Battery Drain Profile: Ice cold thermals, zero background drain, and maximum screen-on duration.

Hi all,

I was wondering if anybody has been experiencing a similar issue to me and might have any thoughts about the cause of this.

It seems (possibly following the 5th July 2026 software update) I have not been able to hear anything during phone calls.

Calling over a different app (e.g WhatsApp) works fine, and I can hear the dail tone when I'm ringing too, it's just I hear no audio at all during the call. The caller on the other end can hear me, but I can't hear them. I have checked sound settings during the call to make sure in call volume is up.

I've checked that Bluetooth is off, I have the same issue when I put speakerphone on, I have tried messing with my network settings, turning WiFi calling on and off etc, but it hasn't helped.

Diagnostics on Samsung members states that everything is working fine, rebooting in safe mode also doesn't fix the issue.

Has anybody else had this issue or has any advice on how to fix this? I really don't want to do a factory reset as I've only just got the phone set up as I want it!

Thanks

The S25 base is perfect for me except the 4000mah battery

People who used the s25 since launch, how has the battery held up till now? Im aiming for 3+yrs on this phone

My use case is social media (tiktok/insta), texting and browsing for 4-6h avg. on Wifi

for context, the S25 at $650 where I live, while the S26 base and S25U are over $1100.

Also I'm upgrading from an A54

EDIT: Thanks for everyone who replied/is replying. seems like the average is 5-7 hours and no degradation whatsoever. That's reassuring to hear really

I'll cut it short. My S21FE is on its last stage of life and i don't really want to spend money on an old phone to get it fixed, the display has like 8 lines and the charging port is acting funny too, not to mention the battery life has degraded too.

So i had these 2 in option: S25 and Iphone 16.

First of all, i don't mind the 60Hz panel that much since ive used my s21fe on 60hz for like 90% of its journey. What bothers me is the repair cost of iphone without applecare and out of warranty. I like the S25, no major issue with it really its decent in every terms but i was thinking I'm used to One UI already. I have never upgraded on the same UI before, maybe i will this time, idk tbh.

What do u guys think? I'd like some input from S25 users.

Thanks in advance!

My samsung is 25ultra 1 to 80 take almost one hour twenty minutes i'm using samsung 60w original charger and five ampere cable

I am experiencing an issue with my S25 when using Bluetooth audio devices.

While playing audio through a Bluetooth device, if I switch to another app (using the Recent Apps button in the bottom left) or lock / unlock the sreen, the audio briefly skips. I cannot quantify the duration precisely, but it seems to be around half a second to one second.

This appears to be a general issue, as I have performed several tests and observed the same behavior:

• with different apps, such as Poweramp when playing music, AntennaPod, and other podcast applications

• with various Bluetooth devices, including two different pairs of headphones and my car's Bluetooth system.

Has anyone the same issue or an ordeal on how to solve please? Thank you!

Hi, I'm going to upgrade my S8 to the S25 or S25 Edge. Which one would you recommend? I'm looking for a phone that I can use for 7 to 10 years. The S25 and S25 Edge are almost the same price. I love taking pictures and I'd like to enjoy them even 7 years from now, but battery life is also important to me. Thanks for your all recommendations in advance.

Im thinking to buy an S25, I found one a good deal but it cant be reset cause of guest profile shi

Can I bypass that or something?

Just wondering if 4 hrs of sot on 70% of battery utilization is good or meh?

I use basic s25 with galaxy watch 7

I removed two Shortcuts from homepage Shortcuts tab. But I want them back in Shortcuts list. I tried the type in url over and over and it usually make a new Shortcut. But the two Shortcuts I deleted won't return even when I visit the sites often. How do I get them back?

Guys; give this EQ a try it will boost the bass and quality of your phone speaker without getting it sounds muffled,

I noticed that the default sounds very tiny and lacking warmth and bass

When I use the volume buttons it varies my ringtone volume instead of media. Any fix?

We waited for this feature a lot but they added to every S25 model except FE

Agora há pouco fui limpar as entradas do meu S25 com um pincel antiestático e álcool isopropílico, que estavam bem sujas. Depois que limpei o alto-falante, notei que lá no fundo a malha que o tampa se desfiou em uma das pontas. Eu deveria me preocupar?

Before getting the Edge, I was pretty worried about how the battery would perform but it has impressed me time and time again. I used to operate the S23 Ultra and the main difference I noticed was how much better the Edge held its charge. I always felt like my Ultra drained when I wasn't actively using it. Whatever optimization samsung implemented to keep this phone cool and the battery to perform well has made this phone a lot more snappy and just overall feels like an extremely well oiled Streamlined machine. Disappointed that they are no longer going to be produced :(

Base S25, S931U1

I commented yesterday in one of the many SoT posts we see here, my time was pretty poor compared to everyone else. I was lucky to get 4 hours max.

Decided to backup and factory reset my S25 and GW7 yesterday.

Needless to say that seems to have done the trick!
