According to your description, if the mobile phone is in a working state such as charging, calling** or surfing the Internet for a long time, when running a game, if the machine is slightly heated, this is because the mobile phone will produce corresponding power when it is working, and it will produce some heat when the power increases, which is a normal phenomenon.

If the machine is abnormally heated, it is recommended:

1.Check if you've been using your phone for too long, such as calling, surfing the web, listening**, or playing games.

Due to the mechanism of the Android system, after the mobile app software is opened, it has been residing in the background process of the mobile phone, after closing the app program in the background process, sometimes they have an inexplicable clear start, and these app software often pops up some information prompts. You can only uninstall the infrequently used app software, leaving valuable system resources for commonly used app software, saving waste of system resources.

Normally, the APP software is in the standby state, at most, it is to interact with the server data, but some Android software developers do not control the program well during the development process, resulting in the mobile phone CPU always waking up. For example, when collecting information such as the geolocation of the mobile phone at intervals, the mobile phone is in standby mode, but in fact, the CPU of the mobile phone is always in the working state, which is very power-consuming. A typical symptom is that when you check the power consumption information of your phone, you will find that the CPU power consumption is relatively high.

3. Enable the power-saving mode.

Find Settings on your phone's desktop, find Power Saver, and enable Power Saver. In particular, you want to enable blocking background data. In the background process, the app software regularly interacts with the server in the standby state, if the number of app software is relatively large, basically the average data has to be exchanged every few minutes, in fact, these data interactions, there is no need for the user, and the resources and power in the mobile phone are completely wasted.

There are three reasons why Samsung S4 mobile phones heat up and consume power quickly:

1. The mobile phone is used for too long or the mobile phone is charged while playing with the mobile phone.

2. There are too many software programs running in the background of the phone.

2. There is a problem with the circuit board or battery of the mobile phone.

Solution: Develop a good habit of using the mobile phone, do not use the mobile phone for a long time, and try to avoid playing with the mobile phone while charging, which will consume the battery of the mobile phone a lot and reduce the service life of the mobile phone;

Close the program manually or use software. Go to Settings - Application Management - Running - Click on Programs - Close (or Stop).

System settings -more-

System Administrator - Click.

Battery: Look at the power consumption of the software, the screen display power consumption, click on the application usage details, click on the application information, force to stop heating, and uninstall the application directly.

Than my S4 suddenly hot a certain e-book software noon consumes all the battery, I uninstall it directly.

Go upgrade the system, it doesn't matter after I upgrade. Because a mismatch between the phone's software and hardware can lead to an increase in good points. Also check whether the battery is bulging, if the battery is bulging, there must be a problem.
