How can i save money without spending it so easily?

You have to try to maximize your utility every time you spend the money.

Open a savings account at the bank. Many banks have accounts specifically for saving for particular goals, like buying a phone. Then you can have it set up that you can't withdraw money from the account for a certain period, or once the amount in the account reaches a certain level. You'll be earning interest on it as well.

Put abit aside everyweek or month. On your pot or where ever you put your money stick notes on saying "don't spend me, you will regret it" for example. Or give someone (parents depending on age) your money to hide therefore you can't find it to spend it!!
