A phone battery only has so many charges before it begins to die.
You will notice when you can't go more than a few hours without plugging your phone in.
This article will show you how to make your battery last through the day as well as a couple years more before you have to replace it.

1. I know that you like to sleep with your significant other on the phone while its charging, my significant other loves to do that.
   Next time though, you might want to just leave the phone calls till the morning after its done charging.
   Every second you are on the phone and your phone is connected to the charger, the battery works extra hard to charge to its fullest and that will destroy the battery life so fast your head will spin
2. Turn off Bluetooth when you don't use it.
   This sucks a significant amount of battery because it is constantly searching for new devices so if you don't use it, turn it off.
   Moreover, having Bluetooth on also presents a whole slew of security issues, but that's a topic for another article.
   
3. When you are in an area with no reception and you don't need your phone, turn the whole thing off.
   The reason why I say this is if you ever go camping and there's no cell phone towers around, your phone will keep searching until it finds a signal.
   This way you will have your phone when you need it, instead of walking around and then finding out its already dead in an hour.
   
4. Dim the screen, usually phones allow you to dim the screen, it saves quite a bit of battery especially if you are one of those people that like to browse the Internet or watch YouTube on your phone all day.
   
5. If all else fails you can always buy an extended life battery or buy an extra battery with you if you are taking a long trip without electricity.
   Extended batteries are usually physically larger and will allow for a greater charge to be stored
