This simultaneous operation can lead to a rapid increase in phone temperature, especially during extended gameplay.
1.2. Streaming High-Definition Content
Binge-watching your favorite shows on YouTube or Netflix can also cause your phone to overheat. Streaming involves constant data loading and continuous display activity, which taxes your phone’s processor and battery.
1.3. Suboptimal Display Settings
Keeping your screen brightness at maximum or using live wallpapers and widgets can contribute to overheating. These features increase CPU usage and power consumption.
1.4. Outdated Applications
Bugs and glitches in outdated apps can lead to excessive processor usage, causing your phone to heat up. Regular app updates often include bug fixes and performance improvements.
1.5. Software Updates
A phone may overheat during or immediately after a software update. The update process can temporarily increase power consumption as the system installs new files and configures settings. Android phones, in particular, have sometimes experienced issues with software updates leading to overheating.
1.6. Navigation Applications
Prolonged use of GPS-based navigation apps like Google Maps or Waze can strain your phone’s resources. These apps require constant GPS and data connectivity, leading to increased heat generation.

Experiment with different cables, ports, and outlets to isolate the cause.
2. Understanding the Root Causes of Overheating
Overheating isn’t always due to external factors. Sometimes, the cause lies within your phone’s hardware or software.
2.1. Overuse and Multiple Active Apps
Running numerous apps simultaneously or using your phone for extended periods can push the processor and battery to their limits, resulting in overheating.
2.2. Malware Infections
Malware can consume significant processing power, leading to increased phone temperatures. Malicious software can also drain your battery and compromise your device’s security.
2.3. Software Malfunctions
Software bugs or glitches can cause apps to malfunction and consume excessive resources, contributing to overheating.
2.4. Direct Sunlight Exposure
Leaving your phone in direct sunlight can quickly raise its internal temperature, potentially causing damage to its components.
3. Android vs. iPhone Overheating: Are There Differences?
While both Android and iPhone devices can overheat, there are some distinctions worth noting.
3.1. Android Overheating
Android devices are more prone to certain overheating causes due to the operating system’s open nature.
/icon_07-1.svg)
These include malware, rogue apps, background processes, and poorly designed third-party cases that restrict airflow.
3.2. iPhone Overheating
While iPhones are generally considered more secure, they are not immune to overheating. Issues like excessive app usage, high screen brightness, and environmental factors can still cause iPhones to overheat.
3.3. Faulty Battery
A faulty battery may be the primary cause of overheating problems. Here are the main signs of a faulty phone battery to watch out for:
| Sign | Description |
|---|---|
| Repeated and Persistent Overheating | Occurs even when the phone is not being used intensively. |
| Rapid Battery Drain | The battery drains much faster than usual during normal usage. |
| Slow or Incomplete Charging | The phone charges very slowly or does not charge fully past a certain point. |
| Sudden Power Offs | The phone unexpectedly turns off even when the battery level is not critically low. |
4. Practical Steps to Cool Down Your Phone
If your phone is already overheating, take these steps to cool it down:

18. FAQs
18.1. Why is my phone hot when charging?
Charging your phone heats it up because the phone’s charging circuit generates heat while the battery is being refilled. Charging a phone on a couch or bed will cause it to heat up even more, because it’s less able to vent heat. When charging your phone, place it on a smooth, firm surface and don’t continue to use it. If your phone gets too hot or overheats while charging, it’s likely because your charging port is broken, the charging cable is worn out, or your battery is damaged. In that case, take steps to prevent your Android or iPhone overheating.
18.2. Is it okay to put a phone in the fridge or a freezer?
It’s never a good idea to put phones or other sensitive electronic devices in a fridge or freezer — this can cause long term damage to your device. Instead, use battery saver mode, remove junk files, and restrict background data use to help regulate your phone’s temperature. If you’re still having trouble cooling your phone down, try restarting it. Ongoing problems could be a sign that you need to remove malware from your phone.
18.3. Is there an app to cool down my phone?
Mobile apps such as AVG Cleaner for Android can help fix causes of overheating by deleting junk files and data-hogging apps that are draining your phone’s resources. Some types of malware can hijack your phone’s resources for nefarious processes, so using antivirus for Android and iOS mobile security can also bring performance benefits.
18.4. How to check phone temperature?
You can check how hot your phone is by using third-party apps such as AIDA64, which displays temperature and other status information of internal components for Android and iOS devices. Other, Android-specific apps, such as Cooling Master and CPU-Z, are designed to detect and prevent overheating by managing processor workload and shutting down problematic apps.
18.5. Can overheating damage your phone?
A phone that persistently overheats can cause long-term damage to your battery, throttle performance, and reduce the overall health and longevity of your device. If your phone is left out in the sun or exposed to high temperatures for extended periods of time, that can also cause long-term damage.
18.6. What is the ideal ambient temperature to keep my phone at?
The ideal ambient temperature to keep your phone at is between 62°F and 72°F (16°C and 22°C). This range is optimal for battery performance and prevents overheating.
18.7. How does a phone’s design impact its ability to dissipate heat?
The design of a phone significantly impacts its ability to dissipate heat. Phones with metal casings often dissipate heat better than those with plastic casings because metal is a better conductor of heat. Internal layout and components also play a role; efficient placement of heat-generating components can prevent hotspots and allow for better airflow.
18.8. Can using a fast charger cause my phone to overheat more than a standard charger?
Yes, using a fast charger can sometimes cause your phone to heat up more than a standard charger. Fast charging involves pushing more power into the battery in a shorter amount of time, which generates more heat. While modern phones have safeguards to prevent overheating during fast charging, it’s still possible for the phone to get warmer than usual. It’s advisable to use fast charging only when needed and to ensure the phone is placed in a well-ventilated area while charging.
18.9. Why does my phone get hot while using mobile data or Wi-Fi?
Your phone gets hot while using mobile data or Wi-Fi because these processes require the phone’s modem to work continuously, which generates heat. Additionally, downloading or uploading large amounts of data can further increase heat generation. The continuous activity and data transfer associated with mobile data and Wi-Fi contribute to the phone heating up during these activities.
