I must do something about battery myself The android bloatware is getting REALLY annoying, and samsung too. all pushing more and more apps.
before i rooted and deleted the bloatware, my batt would last typically 3/4hrs with continuous use, now i get a good 12hrs out of it and im never off the thing tbh, get it done mate you wont regret i put up a list of deletable bloatware on the apps and games thread, if ya interested, youll need root permission though 1st
rooting is pretty simple nowadays tbh , theres apps like kingroot that can do it for you (on google play) once youve done that google your phone model and what apps system apps and files are ok to delete once youre rooted download greenify and set battery drainers like FB insta twattor to hibernate when screen is off - that alone will help a great deal with your battery life before you do any of that you will need to back up your stuff so you can revert to that should anything go wrong
