As a Samsung user, if you have faced an error that says ‘Charging Paused. Battery Temperature Too High’ when you plug into the charger, it can be blamed on either of the two things: the sensor or the battery.
Either the sensor has gone haywire and gives off a ‘false alarm’ of phone overheating, and in turn, the system pauses charging to avoid damage to the phone. Or, another more common possibility is that your battery is overheating owing to some reason or the other (usually long-term usage, degradation, environmental factors, etc.).
In this post, we will discuss how you can fix ‘Charging Paused. Battery Temperature Too High’, while also understanding how phone overheating is damaging to the longevity of the phone.
How to fix ‘Charging Paused. Battery Temperature Too High’?
Below we have listed 9 solutions that can help you fix the error ‘Charging Paused. Battery Temperature Too High’.
Solution 1: Remove the battery, then put it back in
Although this may sound very generic, it works in a lot of cases. If your phone has a minor bug that is causing the error and therefore avoiding the phone from taking up any charge, this solution should help.
If you have a phone that can be opened (since the problem usually occurs in the older models of phones, we are taking the rear end of your phone can be opened), just take out the battery from it, and keep it detached for about 20+ seconds.
Next, hold the reboot button (which is usually the power button) and simultaneously put back the battery into the phone and restart it.
Plugin the charger to see if the problem persists.
Solution 2: Take out the battery and clean the inner parts
It is possible that some hardware problem, possibly some glitch in the sensor, is causing the error ‘Charging Paused. Battery Temperature Too High’. We may not swear by this method, but it might work in some cases: Detach the battery and try cleaning the rear end with a cleaning cloth or an obsolete brush.
Put the battery back in and plug in the charger to check if the problem persists.
Solution 3: Check the charging cable
It is possible that the overheating issues are rooted in the faulty charging cable if you use a USB charger, that is. This can also be the reason for your phone to show the error ‘Charging Paused. Battery Temperature Too High’. In this case, it is obvious that you will need to swap your charging cable to see if the problem persists.
Solution 4: Turn off your camera
If you ever turn to google ‘camera overheats phone’, you will find multitude of message boards that address this problem and justifiably so. If your camera app is on while you are trying to charge your phone, it is possible that the camera is causing the overheating issues and, therefore, the error message ‘Charging Paused. Battery Temperature Too High’.
Turn the app off, especially if you have been long-filming, and unplug the charger. Then, plug the charger again after a while and check if the error is gone.
Solution 5: Use a wall charger
A wall charger is plugged directly into the outlet to supply charge to the device. Even if a device is not plugged into the wall charger, it will still consume electricity if plugged into a socket. Wall chargers supply about 600 amps of electricity, which means they take less time than a USB cable to charge your phone.
Now, how can they be of use when it comes to solving the error “Charging Paused. Battery Temperature Too High”?
These wall chargers, easily available on ebay, cost about $15 and will charge your phone, no matter what. These chargers have only two pins, which implies that the absence of the third pin will not make it mandatory to check the phone stats before charging.
Solution 6: Disable Force GPU rendering
If you have Force GPU Rendering turned on on your phone, turn it off. In case the Developer Mode is enabled on your android, it is possible to enable and disable Force GPU Rendering. This usually exhausts a significant amount of battery since it forces the apps to use hardware 2D rendering, even if these apps/software were not designed or written to use hardware 2D rendering.
Since it can temporarily bork your phone and cause overheating issues, it is best to turn it off and check if the problem still persists.
Solution 7: Perform a factory reset
Before you go ahead and try any of the methods below, we recommend performing a factory reset to ensure that it is the battery/sensor that is causing the error message on your phone and not a bug on some third-party software.
It goes without saying that this shall wipe all of your data and restore the phone to its initial default state; therefore, make sure to back up all your important data that might be lost while performing the reset.
Below we have discussed how you can perform a factory reset on different android versions of a Samsung phone/tablet:
Android OS 7.0+
- Go to Settings on your Samsung device.
- Next, scroll down to the General Management and open it.
- Look for the Reset option, and tap on it.
- Tap on Factory data reset, then scroll down to the Reset option at the bottom.
- Now select tap on Delete All option.
- Then you need to enter your Samsung account password and tap on Confirm. ( This step is only for those who have set up their Samsung account on their device.)
Android OS 5.0+ and 6.0+
- Go to Settings > Backup and reset > Factory data reset > Reset Device
- Then you need to enter your lock screen password and continue.
- Finally, tap on Erase Everything, and wait for the device to restart.
Android OS 4.4+
- Open Settings, go to the General tab and tap on Backup and reset.
- Tap on the Factory data reset > Reset device > Erase everything.
- Now, wait for the device to reboot.
Solution 8: Replace your phone’s battery
If nothing has worked out for you so far, the last thing you can do is replace your battery. More often than not, the battery of the phone wears out gradually and starts causing issues, the most common of which is overheating.
Before you replace your battery, check your battery’s health status using a third-party application/software, or using the default in-built app, if your phone has one. Since nothing so far has worked out for you, it is highly probable that the health stats would not be very ‘crisp’. If that is the case, replace your phone’s battery.
There are two ways to go about it. However, we generally recommend taking the easier route (which means you will need to spend some money). You can replace the battery of your phone yourself, which should not be a problem as long as the rear is openable, or you can take your phone to a verified authorised repair shop that will replace the battery for you.
If you feel underskilled to perform the job, especially when the phone is a tough nut to crack (quite literally), or you do not have the patience to do it yourself, you should let a professional replace the battery. In a lot of phones, if you take things in your hand and try to open the phone and replace the battery yourself, you may end up causing damage to the other components.
For example, the Samsung Galaxy S7 has not only a lot of adhesives that you will need to re-apply once you assemble the phone back, but you will also have to disconnect and reconnect the loudspeaker assembly if you choose to replace the battery yourself. If anything goes wrong, you will have one more thing to worry about.
Besides, when you replace the battery yourself, the waterproofing measures are usually void.
If it’s a desperate time for you and you choose to replace the battery yourself, you can ideally buy a repair kit for your Samsung phone, which costs about $25 – $30. Since you will have to melt the seals that hold the two panels together, you can buy a tool that melts these seals.
We still would not recommend you bring the ‘superhero’, and at the very least, you would not be able to bank on your phone being waterproof anymore.
Solution 9: Under lock your phone’s CPU (use with caution)
We generally do not recommend using this solution if your phone is still under warranty, and as long as you do not have the expertise to work around this solution.
If replacing your battery worked for a while, before your phone turned back to show ‘Charging Paused. Battery Temperature Too High’, this is possibly the last method you can resort to before having to replace your phone completely.
Before we get to how you ‘underclock’, let us give you a brief on what underclocking your phone means. You must have heard of overclocking and underclocking on laptops and gaming gears.
The same mechanism follows in android: On an android phone, underclocking is decreasing the CPU clock speed in order to save battery. For instance, if your phone’s speed is 2.5 GHz, you can go down to decreasing the clock speed to 2GHz or more.
As mentioned, it saves battery, so the maths is simple: you save battery, and you avoid overheating of the phone, and thus obliterate the possibility of the error ‘Charging Paused. Battery Temperature Too High’.
Underclocking your android phone has the following prerequisites:
- Your phone should be rooted.
- You should have a custom recovery installed on your phone.
- If anything goes wrong, you have nandroid backup as a failsafe.
- The phone should be at least 80% charged for making the procedure as smooth as possible. If you are unable to charge your phone to 80%, you can use a wall charger, as mentioned above, before proceeding with underclocking.
To underclock your android phone, follow the steps below:
- Download the custom kernel for your device from a trusted developer. To download the right custom kernel, check your android build and device serial number.
- Once it is downloaded, boot into recovery mode, and tap the install button. If it is a CWM recovery, tap on the ‘install zip’ option.
- Next, navigate to the location where you saved the kernel file before booting your phone into recovery mode.
- Next, flash the file once it is located and wait for the success message to appear on the screen.
- Once installed, wipe Cache/Dalvik.
- Tap on ‘Fix Permissions’ that you will find in the Advanced settings in the recovery section.
- Now, reboot the system and download any CPU manager to underclock your android device.
- If you have downloaded a positively rated and trusted custom kernel, it is likely to have its own apps, including a CPU Manager that you can use to underclock the phone.
How Does Overheating Damage Your Smartphone?
When your smartphone overheats, it can do serious damage that isn’t visible to the eye. The two main areas affected by overheating are the battery and SoC.
Lithium-ion batteries are used in almost every smartphone device because it is the best rechargeable battery available in the market. But it has drawbacks too, which results in overheating of the battery and ultimately your device.
The heating issue is mainly because the lithium-ion batteries degrade with time. The other issue is that these batteries are sensitive to heat, whenever there is overheating, the ageing process of the batteries speeds up, and this can cause serious damage to your device.
System on Chip (SOC)
Overheating of the phone leads to SoC overheating which can permanently damage the chip. Now due to this, you will see a major degradation in the entire smartphone speed. Activities like using wifi with poor connection, excessive Bluetooth, watching online videos and movies, or playing high-end games on your mobile also causes SoC overheating.
Thus, you should always try to avoid phone overheating in the first place.
