Ways to make phone's battery last longer?

Turn down your brightness, obviously, because your phone's screen accounts for about 85% of your battery's usage. If you use a smartphone, you might want to enable the Automatic Brightness setting. Most smartphones have them.

Charge your phone until it's full. This is extremely important. Don't use your phone while it's recharging. This actually makes your battery life shorter every time you do it. It's better to just turn it off while it's charging.

Try using your phone less overall. Any unnecessary use (like Temple Run or unimportant text conversations) should be kept to a minimal.

Nevertheless, your battery life gets slightly shorter every time you recharge it. You'll only have about 30% of your original battery life three years after purchase. (I'm not exactly sure how accurate that last statement is. I remember reading it somewhere, but I don't know where.)

OR, get a phone with a really long battery life. Usually works.
