Samsung Galaxy S24 dying fast? 9 ways to improve its battery life
⚡ Fast fix
- Battery tanking overnight? Check Battery usage first. One rogue app can wreck your day.
- Fresh update installed? Your S24 may still be optimizing in the background for a few days.
- 120Hz looks amazing—but it also eats more battery during scrolling and gaming.
- Weak 5G signal? Your phone may be working overtime just trying to stay connected.
Are you struggling with your Samsung Galaxy® S24's battery life? Whether your phone is dying quicker than expected or you’re just looking to maximize its efficiency, understanding how to manage your device's battery properly can make all the difference.
At Asurion, we’re here to provide you with expert tips on enhancing and preserving the battery life of your Samsung Galaxy S24 so you can stay connected longer without constant recharges. Here’s how to get more life out of your battery without babysitting your charger all day.
Adjust the screen settings
The Galaxy S24’s adaptive 120Hz display looks great—but it can drain battery faster during gaming, scrolling, and video playback. If you’re trying to stretch battery life, lowering motion smoothness can make a noticeable difference.
Go to Settings > Display > Motion smoothness and switch from Adaptive to Standard.
You can also reduce power use by:
- Turning off Always On Display
- Lowering screen brightness
- Using a shorter Screen timeout
- Switching from QHD+ to FHD+ resolution on Galaxy S24 Ultra models
Dark mode can help too, especially on Samsung’s AMOLED displays.
Turn on Power saving mode
Samsung’s built-in Power saving mode reduces background activity, limits performance slightly, and helps stretch your battery when you’re running low.
Go to Settings > Battery > Power saving and turn it on. If you only need your phone for basics like texting, maps, or calls, this can buy you several extra hours of battery life.
Don’t ditch it, fix it

Check battery usage
If your battery suddenly started draining after a software update, don’t panic just yet. Many Galaxy S24 phones temporarily use more power for a few days after a major One UI update while the phone re-indexes apps, rebuilds caches, and relearns usage patterns.
If battery life still feels unusually bad after about 3–5 days, check which apps are using the most power:
Settings > Battery and device care > Battery > Battery usage (On some versions: Settings > Battery > Battery usage)
Look for apps running heavily in the background—especially social media, navigation, fitness tracking, or AI-powered apps.
Limit background apps
Samsung’s newer One UI versions automatically place rarely used apps into sleep states, but some apps can still drain battery in the background. To manage them manually, go to Settings > Battery > Background usage limits.
From there, you can:
- Add apps to Sleeping apps
- Add heavy drainers to Deep sleeping apps
- Prevent unnecessary background activity
Be careful with messaging or health apps though—putting them into deep sleep may delay notifications.
Check your network connection
Bad cellular signal can quietly destroy battery life. If your Galaxy S24 is constantly hunting for a stronger 5G signal, it may burn through power much faster than normal.
If you notice fast drain in certain buildings or areas, try switching temporarily to LTE:
Settings > Connections > Mobile networks > Network mode
Wi-Fi calling can also help reduce battery drain indoors when cellular coverage is weak.
Disable unused Wi-Fi features
Features like Bluetooth®, GPS, nearby device scanning, and NFC can slowly chip away at battery life when left running all day.
Turn off anything you’re not actively using:
- Bluetooth
- Nearby device scanning
- Location
- NFC and contactless payments
You can find most of these under Settings > Connections.
Keep apps and software updated
Battery drain issues are often tied to buggy apps or software versions. Keeping your Galaxy S24 updated can improve stability and battery efficiency.
Check for updates:
- Settings > Software update
- Google Play Store > Manage apps & device
If battery problems started right after an app update, uninstalling and reinstalling the app can sometimes help.
Check battery protection settings
If your Galaxy S24 seems like it’s losing battery quickly, double-check whether Battery protection is enabled. Samsung devices can intentionally stop charging around 80–85% to help preserve long-term battery health.
Go to Settings > Battery > Battery protection. If you need maximum battery life for a long day, you can temporarily disable it and charge to 100%.
Restart your phone occasionally
A quick restart can clear temporary system issues, background processes, and stuck apps that may be draining your battery. If your Galaxy S24 has been running hot or losing battery unusually fast, restarting it is a surprisingly solid first move.
Give your phone time after setup or updates
After transferring data with Smart Switch or installing a major One UI update, give your Galaxy S24 a few full charge cycles before judging battery performance. The phone’s adaptive battery system needs a little time to relearn your usage habits—and yes, it can act dramatic for the first couple days.
If you've tried these steps and still need a little help, we're right around the corner. Schedule a repair at the nearest uBreakiFix® by Asurion store and our certified experts can get your device back up and running as soon as the same day.
FAQ
Why is my Samsung Galaxy S24 battery draining so fast after an update?
Major One UI updates can temporarily increase battery use while your phone rebuilds caches, indexes apps, and relearns your habits. This usually settles down within a few days.
Does the 120Hz display drain battery faster on the Galaxy S24?
Yes. Adaptive 120Hz refresh rates use more power than Standard mode, especially during gaming, scrolling, and video-heavy use.
Why does my Galaxy S24 stop charging at 80% or 85%?
Samsung’s Battery protection feature may be enabled. It limits charging to help preserve long-term battery health.
What apps drain Galaxy S24 battery the most?
Social media, navigation, fitness tracking, streaming, and AI-powered apps are common battery drainers—especially when running in the background.
Is poor 5G signal bad for battery life?
Definitely. Your phone uses extra power trying to maintain weak cellular connections, especially in areas with inconsistent 5G coverage.
How do I know if my Galaxy S24 battery is actually damaged?
If battery life stays unusually poor after troubleshooting, the phone overheats often, or the battery drains rapidly even in Safe Mode, it may be time for a professional diagnostic.
