If you’ve recently picked up a Samsung Galaxy S25 and noticed your battery percentage dropping faster than you can scroll through your favorite social app, you’re not alone.
Reports of rapid battery drain on the Galaxy S25 series have surfaced across online forums, including Reddit and Samsung’s Community pages. Many users report that their devices, some of which are only a few weeks old, struggle to last more than 5 to 6 hours on a single charge, even with light to moderate use, such as texting, using WhatsApp, browsing the web, or watching short videos.
For a flagship phone promising all-day battery life, this can be incredibly frustrating. However, the good news is that, in many cases, there are solutions ranging from simple software tweaks to more comprehensive diagnostic steps.
If your Samsung Galaxy S25, S25+, S25 Edge, or S25 Ultra is draining its battery faster than expected, this guide walks you through what might be causing the issue and how to take action right now.
What’s Behind the Galaxy S25 Battery Draining?
Rapid battery drain isn’t uncommon, especially right after a significant operating system update or even out of the box, when apps and settings are still syncing and learning your usage patterns. But many Galaxy S25 users are noticing the issue well beyond the initial setup window.
Common causes include:
-
Background apps run continuously, even when not in use
-
Misbehaving apps post-software update (e.g., app compatibility issues with One UI 6.1)
-
High refresh rate settings, which make animations smoother but consume more power
-
Always-on connectivity features like Bluetooth, 5G, or location services
-
Poor app optimisation, where third-party apps use more battery than they should
Some users have traced the issue back to OS updates that temporarily disrupted battery management tools, or apps that weren’t optimized for the new software version.
How to Fix Galaxy S25 Battery Draining?
Here’s how to start diagnosing and improving your phone’s battery life. These steps are effective, easy to follow, and safe for any user. No advanced tech skills required.
1. Update Everything: Apps and Software
Yes, everything. Both the operating system and individual apps.
-
Go to Settings > Software update > Download and install to check for the latest One UI or security patches.
-
Open the Google Play Store to update all apps.
Why this matters: Developers often push fixes to address bugs that can cause battery drain. Even system-level apps can be updated independently of the OS.
2. Check Battery Usage
Samsung offers a helpful breakdown of which apps or services are using the most battery.
-
Go to Settings > Battery and device care > Battery > Usage since last full charge.
You may notice an unexpected app, such as a social media platform or email client, causing the Galaxy S25 battery draining even when it’s not in use.
If an app shows unusually high consumption, try:
-
Clearing its cache (Settings > Apps > [App Name] > Storage > Clear Cache)
-
Restricting background activity (Settings > Apps > [App Name] > Battery > Restricted)
-
Uninstalling and reinstalling it if the problem persists
3. Limit Background App Activity
Not all apps need to run in the background. You can limit them without deleting anything.
-
Settings > Battery and device care > Battery > Background usage limits
-
Enable Put unused apps to sleep
-
Review the Sleeping apps list and manually add apps you rarely use
This stops them from refreshing or syncing when not in use.
4. Adjust Display Settings of Your Galaxy S25
The Galaxy S25’s vivid, high-refresh-rate screen is a joy to look at, but it also consumes more energy.
-
Go to Settings > Display > Motion smoothness, and select Standard (60Hz) instead of Adaptive (120Hz).
-
Reduce screen brightness or turn off Adaptive brightness.
-
Use Dark mode to reduce screen energy draw (especially on AMOLED displays).
These tweaks can extend your screen-on time by several hours per day.
5. Turn Off Unused Radios
If you’re not using a feature, turning it off can save a noticeable amount of battery over time.
-
Bluetooth, Wi-Fi, and Location Services should be disabled when not needed.
-
If you’re in an area with weak 5G coverage, switching to LTE only (via Settings > Connections > Mobile networks) can reduce battery drain caused by constant signal searching.
6. Run Samsung’s Battery Diagnostics
Samsung provides built-in tools to identify hardware or software issues causing the Galaxy S25 battery drain:
-
Go to Settings > Battery and device care > Diagnostics, or open the Samsung Members app.
-
Tap Battery status and follow prompts to check for abnormal usage patterns.
This feature can flag apps or system functions that are drawing excessive power and even suggest fixes.
Still Having Issues? Try a Factory Reset (As a Last Resort)
If none of the above solutions improve your phone’s battery life, a complete reset might help. This clears out any lingering bugs or corrupted settings from previous updates.
Before resetting, back up all important data.
-
Settings > General management > Reset > Factory data reset
After the reset, install apps gradually to monitor battery behavior and pinpoint problematic ones.
When to Contact Samsung Support
If your phone continues to drain rapidly despite all these efforts, and especially if it gets warm while idle, it may be a hardware issue. Reach out to Samsung via the Samsung Members app or visit a local Samsung Service Center. Devices under warranty may be eligible for a battery replacement or full repair.
Final Thoughts
The Galaxy S25 series is designed for premium performance, but even top-tier phones can suffer from software bugs or resource-hungry apps. While battery issues can be frustrating, they’re often fixable with a few simple adjustments.
If you’ve been stressing over how quickly your phone drops from 100% to 50%, don’t panic. Start with the basics: update, check app usage, and optimize display and background settings. You’ll likely see a noticeable improvement.
Your smartphone should work for you, not the other way around. And when it doesn’t, a little tech know-how can go a long way in keeping your battery (and peace of mind) fully charged.
