Turn off communications when they are not in use
Do not forget to turn off the Bluetooth service, Wifi, GPS, cellular data and NFC when you are not using them. These services not only drain the battery faster but also slow down the performance of your phone by constantly updating. Turn off them by going to Settings and only turn them on when you need to use those services.
Restart your device
It is always suggested to restart your phone when any type of issue such as battery drain, performance, overheating or camera issue is occurring before you proceed with other solutions. To restart your phone hold the power key, it might solve the problem temporarily.
Deactivate location services
If you are not using maps or any apps like that then there is no need to use location services. When you need to use any such apps you can enable the services which is quite easy. So turn the service off in order to improve the battery life. Disable location services going to Settings.
Remove the unused apps

Uninstall the unused apps to free up the space and to speed up your phone. Try to delete the larger games that take huge space, do not worry the information for most of the games like Temple run is saved in the Game Center, so you do not need to start from the scratch if you want to play them again.
Battery charge cycle
It is important to let your phone go through a charge cycle atleast once in a month. That means charge the battery 100% and use the phone until it is switched off because of low battery. It is good for the battery maintenance and to get exact battery usage data.
Getting notifications for every app is not only irritating but also consumes battery and processing speed. So the apps for which you do not need notifications, turn off this feature for them.
Use Power saving and Ultra saving modes
Navigate to Settings > System > Battery and you will find two battery saving modes- Ultra Power saving mode and Power saving mode. Power saving mode reduces brightness, limits CPU performance, and takes care of other small things to improve the battery life. It let you use the phone without any fancy things like screen on time and vibration.
You can enable ultra power saving mode at the critical time when every drop of battery matters a lot. It limits the number of apps that you can use and activates a grayscale theme to your device.
Use these modes when you need to save battery and you are out of home.
Perform a factory reset
If you tried all the above steps to solve Galaxy S6 or S6 Edge battery drain issue but none of them worked for you, then it is time to perform a factory reset to bring back the phone to the stage as it was at the time of buying. For that:
Go to Settings > Personal > Backup and Reset. This process erases all the data from the phone, so you can back up the important data.
If factory reset also does not work then you need to buy a battery pack.
