How to fix overheating and prevent big battery drain on the Samsung Galaxy S5, Galaxy S4, Galaxy Note 3 and even older Samsung devices? Nowadays, modern smart phones come equipped with fast quad-core and even octa-core processors for the best performance possible and big batteries which last for long periods of time.

However, the fast processor and other factors sometimes make the phone very hot which cause huge battery drain. If you are experiencing overheating and battery drain on your Samsung Galaxy S5, S4, Note 3 or other devices, read below for all possible factors that might be causing it and how you can prevent it.

On of the biggest advantages Android has over other operating systems is the ability to multitask and Samsung has perfected this ability. You can navigate on two different applications at the same time and even open four applications at once on the Galaxy Note 3.


However, once you are done with multitasking, most of the people forget to close the apps. Just pressing he home button is not enough. You have to remove the apps from Recent Apps menu and also should stop every unnecessary activity which is running on the background with Task Manager.

If the apps are left open, they spend a lot of processing power which leads to big battery drain. Always make sure to stop every active application running on the background to prevent battery drain and overheating.

Another reason is the MicroSD card. All major Samsung smartphones support Micro SD cards. They are a great way to store all photographs and music in order to free space on the internal memory of the phone. However, if not treated correctly, MicroSD cards might use a lot of battery juice.



Every time you open the photo or music gallery, the phone automatically runs a service called media scanner. Media scanner scans all the possible photos and music you might have on your phone and then displays them on the gallery. However, media scanner requires a lot of processing power to do this.

And if it runs frequently, it will be very power hungry and will drain the battery a lot. To fix this, you have to stop all the folders with music and photos that you don’t really need. For example, if you have a folder with old photos that you don’t want to see on the gallery, you can stop the media scanner from indexing that folder and the items inside will not be displayed.

To prevent media scanner from scanning these folders, simply create a .nomedia file and put it inside the folder you want. This file will tell media scanner to not scan the selected folder and this will save battery life as well as processing power.

These are a few reasons why the Galaxy S5, Galaxy S4 and Galaxy Note 3 might overheat and lose a lot of battery juice in short periods of time.
