Why Your Android Phone Is Overheating and How to Stop It

Christian Cawley Updated 03-12-2018

Your phone overheats. But is it happening all by itself, or do you have apps running in the background that you don’t know about? Are you streaming a ton of video, or is the weather simply too hot? It’s difficult to pinpoint just why your smartphone overheats.


Perhaps the device becomes sluggish when hot, or maybe it shuts down until it can cool. Either way, this has to stop.

Let’s look at why your phone overheats and how you can fix it.

Obvious Reasons for Your Phone Overheating

Usually your phone overheating happens from a common cause. These include overuse, or remaining connected to a Bluetooth speaker for too long.

Chances are that you might have closed a few apps or restarted your device in an attempt to troubleshoot. Maybe you’ve even Googled a few phrases based on error messages that you’ve seen.

Almost every time, you’ll come across a collection of the same old reasons for your phone overheating:

  • Your display brightness is too high.
  • Your Wi-Fi has been connected for too long.
  • You’ve been playing too many games (often with the additional “it’s not a game console” advice).

By now, no smartphone on the market should overheat for any of these reasons. Let’s look at other causes.

Is Your Phone Really That Hot?

Before continuing, it’s worth taking the time to examine what is hot, and what is not. Your phone under normal use should not be hot. If it is, you have a problem.

However, don’t interpret warm as hot. A slightly warmer feel after playing a game for 15 minutes is normal. But if your phone displays an overheating alert, or you find the device is surprisingly hot to the touch, then you should investigate.

Intensive Camera Use Can Overheat Phones

Phones with top-quality video cameras can end up overheating. This doesn’t happen in all cases, and typically depends on some other factors:

  • Selected resolution and frame rate
  • Screen brightness
  • Environmental temperature

Prolonged camera use can overheat your phone

For example, I recently recorded a video using the front-facing camera, and found my phone soon overheating. This was such a problem to the safe running of the phone that it displayed a warning notice.

In this scenario, my phone was in its flip-cover fake leather case, which features a basic friction stand. The phone was also situated in direct sunlight, although the case shielded it a bit.

While I was using the highest quality settings on the camera, and the video lasted around 20 minutes, it was nevertheless a surprise to receive a warning that the phone would shut down due to overheating.


So while connectivity options, high display brightness, and regular gaming can impact your phone’s temperature, where it is situated and your camera settings can also play a part.

Slow and Overheating? Check for Malware

Malware on your Android device could cause excessive heat. After all, the developers of the malware aren’t exactly interested in the health of your device; they just want your data.

Our look at smartphone malware Has Your Android Phone Been Infected with Malware? How does malware get on an Android device? After all, most users only install apps through the Play Store, and Google keeps a tight watch over that to make sure malware doesn't squeeze through, right?... Read More is a good starting place for dealing with this. If you’ve never enabled app installations from unknown sources Is It Safe to Install Android Apps from Unknown Sources? The Google Play Store isn't your only source of apps, but is it safe to search elsewhere? Read More , you’re unlikely to have picked anything nasty up.

Is Your Case Heating Up Your Phone?

Your case is a common heat factor that many smartphone owners overlook.


Many cases are constructed from plastic or have a large amount of plastic. Even those made with leather have the same problem: the phone is insulated, keeping heat in and cold out.

Is your phone's case causing it to overheat?

For safety reasons, as the phone gets warm (particularly during high-performance tasks), it needs to radiate the heat away, and the presence of a case made from an insulated material prevents this. It’s like exercising in a duffel coat.

Your options here aren’t great, however. Removing your phone from the case is a good start, but if you’re uncomfortable with this (perhaps taking extra care to maintain its resell value), then it is not a viable long-term option.

Check Your Battery and Charger Cable

Another aspect to consider is the state of your battery and the chraging cable.

If you have an older phone that’s been overcharged many times (you should never charge to 100% if you can help it; regularly charge to 80-90% to keep the battery healthy Keep Your Android's Battery Healthy With These Tips Software and apps can only go so far -- what about how to charge and discharge your battery?

Follow these tips to get more juice out of your Android device's battery. Read More should help here.

Phones should not get hot enough to cause problems when charging. If this occurs, the reason could be a damaged battery, a poor-quality charging cable, or a problem with the port.

First try replacing the cable. If this doesn’t help, it’s time think about replacing the battery.

Replace a removable battery if it is overheating

If this isn’t possible (an increasing trend for unibody phones) consider contacting your phone manufacturer about a replacement.

Does Wi-Fi Overheat Your Phone?

Well, no. But your smartphone could overheat due to overuse of Wi-Fi.

Android users are susceptible to apps running in the background and drawing on resources, such as CPU, Wi-Fi, or mobile internet. If apps run in this way, your device can heat up.

On older versions of Android, the Greenify app enables you to identify resource leeches and put the misbehaving apps into hibernation. However, similar functionality is now included in Android thanks to its battery optimization features.

You can also shut off background mobile data use. Open Settings > Apps & notifications > All apps and select the app you want. Tap Data usage to see its activity and toggle the Background data switch off to disable internet access.

You can also use the Force Stop button to close the app immediately.

While this puts background functionality out of service, you can be confident that it also means reduced resource use. This can help to keep your smartphone from overheating.

Ways to Cool Your Phone and Keep It Efficient

Have you been hit by your smartphone getting too hot and slowing—or worse, shutting down? If so, try the following steps to cool your phone down again:

  • Remove the phone’s case
  • Switch on airplane mode to disable all connectivity
  • Move it from direct sunlight
  • Direct a fan at your phone (but don’t put it in a fridge, freezer, or cooler)
  • Reduce the display brightness

Once you’ve done this, try the following to avoid further overheats:

Not only should your phone stop overheating again, but the battery should last longer! Beyond overheating, there are plenty of apps you can use to check if your Android is functioning properly.

As a safety feature, phones and tablets are designed to shut down in extreme temperatures. You’ll just need to wait for it to recover from the high temperatures to put the above into practice. Meanwhile, here’s what to do if your phone or tablet won’t switch on Your Android Phone or Tablet Won't Turn On? 6 Ways to Fix Your phone won't turn on? Don't despair!

    None of this is my problem im using the charging cable that came with the phone its short so i have a extension plugged in but i don't have problems with that on my other phone or my tablet the wifi/3g data is controlled by no root firewall and the screen does not get hot unless the Qualcomm snapdragon 425 cpu and adreno308 gpu are being used for PUBg mobile and they only get warm not hot.

    I don't know what is wrong with my phone i will probably just have to see if i can get it fixed by LG the phone is a 2017 LG K8 (lg us215) i can shut off everything on the phone and it will be 40 - 47 degrees celsius when i wake up around 11:15 central time us & canada

    I have two Android phones (Samsung Note3, Redmi 4X) that both suffer from overheating after falling on the ground for several times. Take Redmi for example, before the impact I read about 50 degree/122F for SoC in CPU-Z when charging and now the number increased to 75 degree/167F. And this overheating could occur for no reason from time to time even when my phone isn't being charged (Sometimes when I browse Twitter the temperature could exceeds 60 degree/140F easily, and Twitter is obviously not a power-intensive application).

    Something must be wrong with my phone but I just couldn't figure it out. The outside of the phone still looks intact after the fall: the screen was not broken and functioning well (thanks to the casing); earpiece, camera, and fingerprint sensor are all working perfectly.

    Usually such heat could only come from three sources: running massive game/benchmark applications, continuous UHD/4K video recording, and short circuit. The first source is easy to exclude since I did not even have a single game installed on my phone, and I did not have a benchmark app either. Based on the amount of heat generated I then suspect that I was being spied by some trojan backdoor on my camera. However, after I removed SIM card and disable wifi, bluetooth, the heat continues, and I observed no significant diskspace change on my phone during overheating. That left short circuit to be the most likely source responsible. But where could that short circuit be in? Battery? SoC? How can my phone suffer from an internal short circuit but still works normally? I am really at my wit's end now.

      You can get a good new battery on Amazon or ebay for about $20. I just bought one for my Note Edge. I have read batteries usually only last 1.5-2 years under optimal conditions (not too hot and not too cold).

    I am using Xperia Z5 Compact. My phone is overheating since i dropped it in a pond. I knew my mobile was only splashproof regardless the IP68 sticker. I immediately removed it out of the pond and switched it off. I put it in a zip lock plastic bag and then i put the bag inside a large rice container. After two days i took my phone out. Inserted my sim card and micro sd. Everything was fine after two days or so. It started heating up while i was using Snapchat and it is heating eversince. PLEASE HELP.

          Certainly an option -- there's a chance that an app you have installed has caused the problem. But for a new phone, it could be one of the pre-installed bloatware apps.

          Hi Christian! U know what i did? I didn't bother restoring d factory data settings anymore. I just unistalled DU Battery Saver and DU Speed Booster and it's settled. Although it sometimes heat sparingly, but that doesn't slow it down anymore.

    Pokemon Go is really my issue. But I also have a Sony Xperia Z3+ so known issues with overheating. Pokemon Go really saps my resources though. Drains battery fast and heats it up super fast. So what do I do? If I want to keep the game going, I sit it on an icepack. Yep, an icepack. I do have a flexible plastic case on the phone but it got hot even without it. I also wrap a cloth around the ice pack. I can get the phone too cold, at which time the touchscreen can get wiggy. So I take it off and let it warm up again then back on the ice pack.

    I'm considering getting a Z3 (no plus) instead but will probably still need to use the ice pack when I spend a long time on Pokemon Go. Until Niantic solves that problem and lessens the resource hogging of the app, anyway.

    Simple answer is DON'T PLAY GAMES ON UR PHONE. ... nearly every phone I've had broke cause of playing games they will only reason heat any phone as there designed for mostly pads not smartphones they run at different speeds and if u r play like a fast games it will warm up fast but if u play a slower game like chess urban phone won't burn up too fast . Driving games oh big no no and most pool too play slower games like chess tic tac toe slower games will keep ur phone fresh

    I dont have anything running in my background, and as soon as I start a game, in five mins its hot. Its an android tablet, not a phone. I bought it so I could play match 3 games. Im not doing anything wrong... Its not wifi because its only just been turned on.

    I hardly have anything on it... and have no bluetooth speakers attached. Just charge it up then turn it on.... play for five mins and its red hot. Followed everyone's advice online and it hasnt helped. So gutted :(

    I suppose the idea of "underclocking" the phone's CPU won't work?

    Ultimately a lot of the heat is just a matter of the CPU (which is just a glorified over-organized silicon space-heater) being overworked. There really should be a way to throttle back the clock rate to reduce this... But apparently there's not.

    Hi Christian,
    I was having issues with the phone getting really hot. It may require the phone to be rooted to work optimally though.
    So what would you recommend to do? Regards Arsham

      Do you know why, or suspect which app is causing the phone to overheat?

    I've drilled holes in my plastic case to help get air to my phone to help it cool. I used to do this to the cheaper snap on cases for my iPod touch it does help.

    Hi Christian. You say "never charge y phone up to 100%". Pls explain, how a usual phoneowner can manage this in a practical way??? I can not walk over there every half an hour just to have a look at the percentage of battery. Charging over night, as probably the biggest part of the people are doing, brings 100% in the morning;-)
    So what would you recommend to do? Regards Viera

      Most phones drop to trickle charge after reaching 100%, so this is somehow controlled. It is conceivable an app with an adjustable "drop to trickle" level, but I haven't seen one (just hundreds of "battery saving" apps that just shut down systems).

      Failing that, some external hack that turns off and back on the charger at selectable levels, controlled from the phone via wifi (or bluetooth, or even the earphone jack). Maybe one of those wifi controlled home automation AC outlets.
      I smell project.

      Hey Viera

      I think Fik makes a good point, as it is impractical often, so a project that makes use of smart plugs might be ideal.. I'm in a position where I can charge during the day, but obviously that's not the case for many. In my case, I imagine I charge overnight - and therefore to 100% - about 30% of the time.

    I was having issues with the phone getting really hot and installing the app greenify took care of it. It may require the phone to be rooted to work optimally though.
