How to fix an overheating app: Step-by-step removal

How to Fix an Overheating App: A Step-by-Step Guide

Few things are more frustrating than your phone turning into a pocket heater, especially when you know a specific app is the culprit. The good news is, in most cases, you can fix it yourself in a few minutes. Heres the simple truth: overheating happens when an app demands too much from your phones processor for too long. The solution is a combination of immediate first aid and smart, long-term adjustments.

Why Is My Phone Overheating From an App?

Think of your phones CPU like a car engine. When an app revs it too hard—through intense graphics, endless background processes, or buggy code—it generates heat. Your phone responds by lowering performance to cool down, a process called thermal throttling. In extreme tests, this can cut performance by up to 46%(reference:0). This is the main reason your phone feels sluggish and hot at the same time. A key temperature threshold to watch is above 49°C (120°F); while normal use should see temps return below 36°C (97°F) within 10 minutes after stopping(reference:1)^[2].

Immediate Fixes: What to Do When Your Phone Starts Overheating

When your phone feels like its about to take off, these are your emergency brakes.

1. Force Quit the Overheating App

Dont just swipe it away. On Android, go to Settings > Apps, select the app, and tap Force Stop. On iPhone, swipe up from the bottom and flick the apps preview off the top of the screen. This immediately kills all its processes, stopping the CPU from being pushed to its limits.

2. Give Your Phone a Breather

Take the phone out of its case—cases trap heat like a blanket. Move it away from direct sunlight, your cars dashboard, or any warm surface. A simple restart also works wonders, clearing out any temporary system glitches that might be keeping the app stuck in a loop. To be honest, 90% of the time, this is all you need.

App and System Maintenance: Fixing the Root Cause

If the overheating keeps happening, its time to look at the app and your phones software.

Update the App and Your Phone's OS

An outdated app is a prime suspect for heat issues. Developers constantly push updates to fix bugs that cause high CPU usage and battery drain. Head to the Google Play Store or Apple App Store and install any pending updates. The same goes for your operating system. Whether its Android 16 or iOS 19, new OS versions often include critical performance patches. Reports have linked iOS 19 and Android 16 beta releases to fix app overheating android during basic tasks like browsing or messaging(reference:2)(reference:3). An update can squash those bugs instantly.

Clear the App's Cache (Android) or Reinstall (iOS)

Over time, an apps cache—its temporary storage—can become bloated or corrupted. This corrupted data can force the app to work harder, generating unnecessary heat. On Android, go to Settings > Apps, select the app, tap Storage & cache, and hit Clear cache. For iPhones, which dont have a direct cache-clear option, simply delete the app and reinstall it from the App Store. Its a digital deep clean.

Long-Term Fixes: Stop the Overheating for Good

To make sure the problem doesnt come back, you need to control how apps behave in the background.

Check Battery Usage to Find the Culprit

Your phones battery settings are like a detectives notebook. Go to Settings > Battery (or Device Care on Samsung) to see a list of apps sorted by power consumption. If a particular app is at the top, its likely the source of your heat. Some apps are notorious for this. For example, Netflix can consume up to 1500% of a charge (cumulative usage), with TikTok not far behind at 825%(reference:4)(reference:5). A significant portion of this drain can come from reduce app battery usage and heat alone(reference:6)^[4]. If you see an app you barely use up there, its time to take action.

Restrict Background App Refresh

Many apps constantly refresh their content in the background, even when youre not using them. This is a huge source of hidden heat and battery drain. On iPhone, go to Settings > General > Background App Refresh and turn it off entirely or for specific apps. On Android, go to Settings > Apps, select the app, and tap Mobile data & Wi-Fi to disable Background data. This simple tweak can extend battery life and stop app from making phone hot while its just sitting in your pocket.

Scan for Malware That Drains Power

This one surprises most people: malware can be a major cause of overheating. Malicious apps often use your phones resources to mine cryptocurrency or perform ad fraud, tasks that run constantly in the background and generate massive heat.

In 2025 alone, Google Play Protect detected over 27 million new malicious apps from external sources(reference:7). Symptoms of infection like the Badbox malware include high CPU usage and overheating(reference:8)^[6]. On Android, run a scan with Google Play Protect (Settings > Security > Google Play Protect). If you find a malicious app, uninstall it immediately. If your phone keeps overheating for no reason, its worth a check.

When to Consider Hardware or an Alternative App

If youve tried everything and a specific app still turns your phone into a hot plate, the app itself might be poorly optimized. In this case, your best option is to find an alternative app that does the same job without burning a hole in your pocket. However, if your phone overheats no matter what app youre using—even when idle—you might be facing a hardware issue, like a failing battery. If the problem persists after a factory reset, its time to consult a professional repair service. To prevent future issues, learn how to cool down a phone from a rogue app before your hardware sustains damage.

App Overheating Fixes: Quick Actions vs. Deep Clean

Quick Actions (Emergency Fix)

- Force quits the app, removes phone case, and restarts the device to stop immediate CPU load.

- Phone is hot to the touch right now; you need an immediate cooldown.

- No—this stops the immediate symptom but won't prevent future overheating from the same app.

- 1-2 minutes. Provides instant relief.

System Maintenance (Root Cause Fix)

- Updates the app/OS, clears corrupted cache, restricts background processes, and scans for malware.

- The same app overheats your phone repeatedly, even after restarting.

- Yes—addresses the underlying software issue, stopping the problem at its source.

- 5-15 minutes. May include waiting for downloads to complete.

Mark's Hot Phone Saga: From Frustration to a Cool Fix

Mark, a project manager in Chicago, noticed his phone getting uncomfortably hot every afternoon while using a popular navigation app. The battery would plummet from 80% to 20% in under two hours, and his phone became so slow that typing was a nightmare. He was convinced his phone was dying and started researching new models.

His first attempt was to close other apps, but nothing changed. He even tried a factory reset, which was a huge time sink. Nothing worked. He was about to give up when he checked his battery settings and saw the navigation app using 47% of his battery, mostly from background location requests.

The breakthrough came when he realized he didn't need the app running all the time. He went into his phone's settings and changed the app's location permissions from 'Always' to 'While Using the App.' He also turned off background app refresh for that app.

The result was immediate and lasting. His phone stopped overheating, battery life returned to normal, and he saved himself the cost of a new phone. All it took was two minutes in the settings menu.
