How to Fix Battery Drain Issues on the Samsung Galaxy S24 Ultra?

The Samsung Galaxy S24 Ultra is a powerhouse—loaded with cutting-edge features, an advanced processor, and a stunning AMOLED display. But even with its 5000mAh battery, some users may experience unexpected battery drain that affects daily usage.

If you're a repair professional helping clients troubleshoot the Samsung Galaxy S24 Ultra, or an individual user looking to fix the issue yourself, this comprehensive guide covers both software and hardware solutions to improve battery life. We'll also guide you on where to source replacement parts in the UK if the problem turns out to be hardware-related.

Why Is My Galaxy S24 Ultra Battery Draining So Fast?

Several factors can contribute to fast battery drain—even on a brand-new flagship like the S24 Ultra:

• High screen brightness or refresh rate (120Hz)
• Background app activity
• Software bugs after updates
• Misconfigured battery settings
• Faulty battery or charging circuitry

Let’s break down the most effective ways to fix these issues.

Step 1: Check Battery Usage Stats

Start by identifying which apps or features are consuming the most power.

How to Check:

• Go to Settings > Battery and Device Care > Battery
• Tap Battery Usage

Look for apps using a high percentage of battery while in the background. Social media apps, games, and poorly optimized third-party tools often top the list.

What to Do:

• Force stop or uninstall apps that consume excessive background power
• Clear cache and update battery-hungry apps regularly

Step 2: Optimize Display Settings

The Galaxy S24 Ultra’s 120Hz refresh rate and high brightness are stunning—but they eat battery fast.

Tips to Optimize:

• Refresh Rate: Switch from Adaptive to Standard (60Hz) via
• Settings > Display > Motion Smoothness
• Brightness: Enable Adaptive Brightness
• Dark Mode: Use Dark Mode to reduce screen power draw

These simple changes can save several hours of battery life per day.

Step 3: Enable Battery Saver Mode

Samsung’s Power Saving Mode is more intelligent than ever. It now allows for customization without sacrificing core features.

How to Enable:

Go to Settings > Battery > Power Saving Mode

Enable features like Limit apps and home screen, Limit CPU speed, or Turn off 5G if not needed

You can also create a custom battery profile for travel or work days when you're on the go.

Step 4: Restrict Background App Usage

Many apps run in the background and continuously ping the internet, draining your battery.

How to Restrict:

Go to Settings > Battery > Background Usage Limits

Enable Put unused apps to sleep

Add rarely used apps to Deep Sleep manually

Step 5: Turn Off Always-On Display (AOD)

Although it’s minimal, the Always-On Display consumes power throughout the day.

How to Disable:

Go to Settings > Lock Screen > Always On Display

Turn it off or schedule it only during certain hours

Step 6: Update to the Latest Software

Samsung often releases firmware updates that address battery optimization issues and security patches.

Go to Settings > Software Update > Download and Install

Ensure auto-updates are enabled for both system and apps

Pro tip: Also, update Google Play Services, as outdated services can drain your battery even if everything else is up to date.

Step 7: Check for Rogue Services and Sync Settings

Cloud backups, Google Sync, and location tracking may be running more frequently than needed.

Adjust Settings:

Google Account > Settings > Sync: Disable sync for unnecessary services like Docs, Sheets, or Photos

Location Settings: Use Battery Saving Mode under Settings > Location > Location Services

Disable Nearby Device Scanning under Connections > More Connection Settings

Step 8: Factory Reset (if software fixes fail)

If you've tried everything and still see excessive battery drain, a factory reset might help, especially after major OS updates.

Before Reset:

Backup everything to Samsung Cloud or Google Drive

Go to Settings > General Management > Reset > Factory Data Reset

This step can eliminate hidden software conflicts or corrupted app data causing battery issues.

Step 9: Diagnose Hardware Issues

If your Galaxy S24 Ultra is still draining quickly, there could be a hardware issue at play:

• Battery degradation or manufacturing defect
• Faulty charging IC or logic board
• Liquid damage from exposure to moisture or humidity

Step 10: Replace the Battery (If Needed)

Even though the Galaxy S24 Ultra has a large battery, defects or early wear can still occur.

Signs You Might Need a New Battery:

• The phone is heating up during basic use
• It shuts off unexpectedly at high battery percentages
• Battery health reports < 85% capacity (via diagnostic tools)
