For people that are either having problems with their battery draining fast or people that don't have the Note series or people that don't like the battery average usage of their device or even people that want more battery life when playing games. Below are my favorite and most used options when increasing my battery life.

1) Downgrade To Factory Version
More often than not, this increases the battery lifespan of the device compared to the updated version because the factory version correlates with the battery specifications.

2) Delete Apps You No Longer Use
This is a popular way to save battery. Sometimes these apps do not load physically buh when there is an internet connection , they do some background activities and this kills battery.

4) Consistent Removal Of Running Background Activities
You do this by going to Power >> Advanced >> Battery Usage and removing some running activities u no longer use.

5) Airplane Mode Whenever U Don't Use The Network

6) Underclock your device
Most efficient way of saving battery life. This option requires root privileges. It saves battery by reducing the performance of your phone so get ready to witness a below average performance.

Remember this is a very aggressive way of saving battery life. If u want a more friendly or babyish{:16_10:} way of saving ba3 then you...
