The first option is to remove any apps you don't use. At least the ones that you can remove. Usually it is the ones you have personally installed. In regard to other apps, you can often remove any updates that are added, if you don't wan them and they are causing drains on the battery. There is also the option to turn the apps off (disable them) rather than remove them. Again, you would no longer be able to use them though.
Some apps, no matter what you do, can be pretty darn persistent. I have this issue with a weather one on my phone, that I never use, never have used, and constantly am turning the darn thing off. The phone won't allow uninstalling or disabling it. Some apps they put on the phone before it is sold are persistent (and annoying) little things. Those I don't have a way to remove/stop... yet!
