Phone heating up and draining battery
Normally a phone is heating because the battery is working hard due to which draining of battery occurs also. If a phone’s heat coming from the back of your phone, it’s likely your battery. Nowadays all smartphones use powerful lithium-ion batteries that release heat as they generate electricity. That’s why a little heat is normal, especially if you’ve been using your phone for a while. Some of the common causes of phone overheating such as malware, background app running. Today in this blog we will discuss about why Phone is heating up and draining the battery life?
In mobile 80% of overheating issues are due to faulty batteries and battery connectors, 10% are due to board shortages within the battery IC and 10% are affected by bugs within the current operating system (OS) which needs to be formatted and or updated to the latest firmware.
When Does the Mobile Phone Overheat?
Little heating is normal with any phone or tablet . There is nothing serious to worry about. But overheating of a mobile phone and battery draining fast is a serious problem and needs immediate attention before the phone gets dead.
A phone may suffer overheating under the following situations:
- Phone overheating while playing games
- Phone heating up while charging
- Sometimes phone overheats and won’t turn on
How Phone is heating up and draining battery
Mobile phone temperature will increase whenever you’re using it for long period of time, running power-intensive apps, or using more apps than usual.
Watching videos for long time
Watching YouTube or Netflix for season-long sessions is just as detrimental to your phone’s health as marathon gaming. In simple words if anything that keeps your screen on for long periods of time and uses your phone’s GPU will cause the device to heat up.
Gaming for long periods of time
Much like PCs, gaming on a smartphone takes the CPU and GPU to their limits, which causes them to generate a lot of heat.
You have less-than-optimal settings
Turning the brightness way up, collecting all those widgets and 3D wallpapers, and using the sleep setting for a long session of audio or video are all rather taxing on a phone’s performance.
App and OS issues
Certain bugs in apps and your OS can cause your phone to overheat or misbehave. Because these apps have to run on different types of devices using different configurations and operating systems, they may act optimally on some, less so on others.
Malware can heat your phone
Since malicious apps are usually unoptimized pieces of code, they uses your phone’s CPU and memory, throttling them and generating a lot of heat. One of the amin reasons is cryptojacking.
Mining cryptocurrency takes a lot of processing power, and miners are often torn between the cost required to mine the coins and the market value of the coins themselves. The hacker takes over a system’s processing power and uses it to mine cryptocurrency without informing the user.
If an app has a bug or other problem, it may cause increased phone temps by overusing your device’s processor. Keeping your apps and operating system updated is important because updates often include bug fixes. After you apply the update, your phone should have better performance and overheat less frequently.
A phone may overheat during or right after an update. This can be because there was a bug in the OS that required fixing through the update, which can require increased power at the moment (but shouldn’t trigger a long-term overheating issue).
It means getting contact to the sunlight. This will also prevent the touchscreen from working properly and cause the battery to drain faster. In addition to sun and heat exposure, water damage can also cause phone overheating.
Which part of phone is heating and draining battery
Back of the phone
If the back of your phone is getting hot, your battery may be overheating because of lose efficiency over time. As Lithium-ion batteries are generally safe, but malfunctions can occur. A hot battery could also need to be replaced, especially if it’s older.
Bottom of the phone
While charging if you feel that the bottom of the phone is then the problem might be with the charger. The most reliable charger will be the one from your phone’s manufacturer. If you use any third party charger of low budget then it may cause heating problems.
Above the battery
If your phone is not heating due to the battery or charger, then the temperature increase might happen due to heavy work of the processor or due to direct sunlight.
Stop phone from heating and prevent from battery draining
Avoid direct sunlight to your phone:
The easiest way to prevent overheating is to keep your phone out of the sun.
Turn off unused apps on your phone:
You have to open all the apps and close all one by one.
Avoid turning your screen brightness up:
Try to use your phone on a minimum brightness by doing this your battery health will remain good also.
Turn your phone to airplane mode:
It allows you to continue to use basic functions on your phone.
Update your apps
Buggy apps can cause overheating, and updating your apps usually fixes this kind of problem. If not then uninstall the app.
How to cool your phone down
Remove the case
A skin or phone cover can act as insulation, causing a buildup of heat. Remove it to let the phone cool off. If the problem persists, use the phone without it.
Turn off unnecessary settings
Too often, people leave GPS, Bluetooth, or Wi-Fi options turned on, even when they don’t need them. Turning off unneeded apps can end overheating and save battery life. Better still, turn on Airplane Mode when you don’t plan on using your phone.
Keep your apps up to date
Updating is essentially another name for optimizing. The more optimized an app is, the fewer resources it uses, which translates to less of a likelihood that it will heat up your phone.
Change the charging cable
Every once in a while a faulty charging cable can cause the charging unit to malfunction. If the heat is mostly concentrated around the cable port, then you might consider switching to another cable.
Reduce your screen brightness
Keeping the screen at a reasonable brightness level will reduce the strain on your phone’s battery (and your eyes).
Fully close apps when not using them
The more apps you have open at once, the harder your phone has to work. Close apps when you’re finished using them.
Apps to know the temperature of the CPU:
- CPU monitor
It’s one of the best and powerful CPU monitoring app available for Android smartphones. With this app, you can effectively monitor your CPU temperature and frequency in real-time.
CPU-Z is probably the best app on the list that can be used to monitor the CPU temperature. It has a dedicated panel for temperature where it shows CPU temperature, the temperature of various sensors, etc.
- CPU/GPU meter
The app shows some of the essential information like CPU utilization, CPU Frequency, CPU temperature, Battery temperature, Available Memory, GPU Utilization/Frequency, etc.
- 3C CPU manager
It’s a CPU control app for root users, which shows a summary of CPU/GPU loads, frequency, and temperatures. Apart from that, it also lets you configure the governer settings, view frequency usage table, etc.
- Cooling master
it detects CPU overheating, it immediately scans and shows you the apps responsible for that.
Excellent product. Thanks
