I get it — dealing with an overheating Galaxy S25 Ultra can be really frustrating. I’ve been in the same boat, wondering why my phone feels like a mini heater every time I plug it in. But here’s the good news — you don’t have to live with it. After some digging, I found some simple yet effective fixes that can actually Fix Galaxy S25 Ultra Overheating While Charging. So, grab your phone, and let’s sort this out together!

Why Does the Galaxy S25 Ultra Overheat While Charging?

I know how frustrating it is when your Galaxy S25 Ultra feels like a pocket-sized heater while charging. Before we jump into the fixes, let’s figure out what’s actually causing the problem. Once you know the reason, fixing it becomes much easier.

Here are some common reasons why your S25 Ultra might be overheating:

1. Fast Charging – The Heat Booster

Fast charging is super handy when you’re in a rush, but it’s also one of the biggest heat generators. Your phone works harder to push more power into the battery quickly, and that naturally creates extra heat.

2. Background Apps – Silent Battery Killers

Even when you’re not using certain apps, they can still be quietly running in the background. Apps like social media, messaging, or GPS services often keep working without you noticing. These apps drain power and heat up your phone without warning.

3. Outdated Software – The Hidden Culprit

Running outdated software can cause performance hiccups. Samsung regularly releases updates to fix bugs, improve performance, and manage battery usage better. Skipping those updates can leave your phone struggling, which may lead to overheating.

4. Corrupted Data from SmartSwitch – The Sneaky Issue

If you recently used SmartSwitch to transfer data from your old phone, there’s a chance some corrupted files came along for the ride. This can cause your phone to behave oddly, including overheating during charging.

5. Environmental Factors – The Invisible Trouble

Where you charge your phone also makes a difference. If your phone is charging in a warm room or inside a thick case, heat can get trapped. This can make your device feel hotter than usual.

What Now?

Don’t worry — now that you know what might be causing the problem, you’re halfway there. Up next, I’ll walk you through some simple but effective fixes that can cool down your Galaxy S25 Ultra and keep it running smoothly. Let’s get started!

Quick Fixes for Immediate Relief

If your Galaxy S25 Ultra is heating up right now, I know how worrying that can be. The good news is that there are a few quick steps you can take to cool it down fast. Think of these as your emergency tricks — they won’t fix the root cause, but they can provide instant relief.

Here’s what you can do:

1. Remove the Phone Case – Let It Breathe

Your phone case might be trapping heat. Some cases, especially thick or leather ones, don’t allow enough airflow. Removing the case while charging can help your phone cool down faster.

2. Move Your Phone to a Cooler Spot

Is your phone sitting on a bed, sofa, or near a window with sunlight? Soft surfaces and warm environments can make overheating worse. Try placing your phone on a hard, cool surface — like a table or countertop — to help it cool down.

3. Disable Fast Charging (For Now)

Fast charging is convenient, but it also generates more heat. Turning it off temporarily can reduce heat buildup. Here’s how you can disable fast charging:

• Go to Settings.
• Tap on Battery and device care.
• Select Battery.
• Find More battery settings and tap it.
• Toggle off Fast charging.

Once your phone cools down, you can enable fast charging again when needed.

4. Turn On Airplane Mode – Give It a Break

Airplane mode temporarily stops calls, messages, and data services. This reduces background activity, giving your phone a much-needed break.

To enable Airplane mode:

• Swipe down from the top of your screen.
• Tap the Airplane mode icon.

This step is especially useful if you’re not expecting calls or notifications while charging.

Why These Steps Matter

These quick fixes won’t solve deeper issues, but they can prevent your phone from getting dangerously hot at the moment. Once your phone cools down, it’s time to try the long-term solutions I’ll share next. Let’s keep going!

Proven Solutions to Fix Galaxy S25 Ultra Overheating While Charging

Here are step-by-step solutions that can cool down your phone and improve its performance. Follow these steps carefully, and you’ll soon see positive results.

Step 1: Wipe Cache Partition

One of the most effective fixes is wiping the cache partition. Why? Because over time, your phone stores temporary files that can build up and cause performance issues — including overheating.

Think of it like cleaning out a messy drawer. Removing these unnecessary files can instantly improve your phone’s speed and cooling.

Here’s how you can wipe the cache partition:

1. First, turn off your phone completely.
2. Now, connect your phone to a PC or another Samsung device using a USB cable.
3. Wait for the charging icon to appear on your phone’s screen.
4. Press and hold the Volume Up and Side key at the same time.
5. Release both keys when you see the Samsung logo.
6. You’ll now enter Recovery Mode. Use the Volume keys to navigate and highlight Wipe Cache Partition.
7. Press the Power button to confirm.
8. Finally, select the Reboot system now to restart your phone.

Many Galaxy S25 Ultra users have found this method incredibly helpful — and chances are, it might fix your overheating issue too.

Step 2: Enable Battery Protection Feature

Samsung’s Battery Protection feature is designed to prevent your phone from charging beyond 85%. Why is this important? Because charging to 100% every time generates extra heat and can stress the battery.

Limiting the charge to 85% reduces this stress, which helps in controlling overheating.

Here’s how you can enable Battery Protection:

1. Open the Settings app.
2. Scroll down and tap Battery and Device Care.
3. Select Battery and then tap More Battery Settings.
4. Now, enable the Protect Battery option.

This feature is especially useful if you tend to leave your phone charging overnight or for long hours.

Step 3: Identify Power-Hungry Apps

Certain apps — especially power-hungry ones — may be quietly draining your battery and causing your phone to heat up. Apps like YouTube, Android Auto, or even some social media platforms can push your phone’s resources to the limit.

Here’s how you can find these battery-draining apps:

1. Go to Settings → Battery and Device Care.
2. Tap Battery and select Usage Since Last Full Charge.
3. Here, you’ll see a list of apps consuming the most battery.
4. Identify any apps that are consuming an unusual amount of power.
5. Tap those apps and choose Force Stop or Uninstall if they’re not essential.

Reducing background activity this way can have a big impact on your phone’s temperature.

Step 4: Update Your Device Software

Outdated software can sometimes cause performance glitches, which may result in overheating. Thankfully, Samsung frequently releases updates to fix bugs and improve overall performance.

Here’s how to check for updates:

1. Go to Settings.
2. Scroll down and tap Software Update.
3. Select Download and Install if an update is available.

Even if your phone seems up to date, it’s worth checking regularly since new updates often include performance improvements.

Step 5: Reset Network Settings

You might be wondering, What does network have to do with overheating? Well, poor connectivity can force your phone to constantly search for signals, putting extra strain on the device — which generates heat.

Resetting your network settings can fix this.

Here’s how to reset network settings:

1. Go to Settings.
2. Select General Management.
3. Tap Reset → Reset Network Settings.
4. Confirm the reset and restart your phone.

This step is especially helpful if your phone tends to overheat when you’re using mobile data or connecting to Wi-Fi.

Step 6: Real User Experiences and Solutions

Sometimes, hearing what’s worked for others can make a big difference. Here are two real-life solutions that Galaxy S25 Ultra users have shared:

“I wiped the cache partition, and my phone no longer overheats!” — GlennTech (Samsung Community Member)

“Disabling fast charging worked for me. My phone stays cool now!” — Galaxy S25 Ultra User

These simple steps have helped many users resolve overheating issues — and they could work for you too.

Step 7: Recommended Accessories for Cooling

If your phone still gets warm often, you may want to invest in accessories that improve cooling.

Here are some popular options:

• Cooling Fans for Smartphones: These attach to your phone and improve airflow, reducing heat buildup.
• Heat-Dissipating Phone Cases: Specially designed cases with ventilation gaps can help keep your phone cool.
• Charging Docks with Ventilation: These stands allow better airflow while your phone charges.

Using one of these accessories can prevent heat issues, especially if you use your phone for gaming, streaming, or video calls.
