How to make my iPhone battery life last longer?

My iPhone 5s is always going dead when I need it most so how can I make it last longer thanks

Shut off location services, close some apps, lower the brightness on your phone, delete some apps. It really all depends on what all you have running 24/7. Facebook, sports apps, weather apps and anything that uses your current location can run your battery down extrememly. I know that by lowering the brightness will help some.

Take all of the apps you don't need and get rid of them and get a ram cleaner app that will help:-) and the screen brightness on low and don't leave apps running by pushing the middle button exit the app properly otherwise its using battery to keep the app runing

Try not to waste unneeded time on things waste life like hell…
Also make sure it is fully turned off and if you need it lots then can you get somit like a portable charger, i'm not sure but just try to use it only when needed if you are always in use of it.

I hope this helps even tho it probably doesn't ; P
