Is it important to update your iphone 4s?

When you update your iphone 4s its just
A: taking up space, making your phone slower
B: fixing any bugs but causing other
So my question is… Is it nessisary to update my iphone 4s? Is it important?

Not really. If there's a giant glitch, then yes. Because most updates fix that. I remember when I got my iPhone 5 there was a Wi-Fi issue and a glitch that made lines go across the keyboard so you couldn't type, and the update fixed that.

And 6.1 on my iPhone 4S actually made it run faster.

One IS IT INPORT TEN YES SLMETIMES ITZ SLOW BE4 you DO THAT WRITE All your NUMBERS DOWN FIRAT.
