It is better to buy a new phone or repair my phone (Apple 6s)?

So my iPhone s battery just stopped working as well as it was last week. This was suddenly, then my phone fell in the toilet yesterday and now the LED doesn't work. To add to that, the screen edge is broken. (also the phone got slower but probably a reset would solve that) Should i repair my phone or get an iPhone 8? I'm trying to get the best out of my money. (yes i have considered getting an android but once you go black you never go back.

Added (1). I forgot to mention that I have had this phone for 2 years!

Buy new, you will spend too much on repair, like on a refurbished iPhone 6

Should check to see the repair costs vs the cost of getting the 8 & see which makes more sense. If the 8 costs more to get, but not by much, I'd go for it anyway.

Probably anew one its going to be like 300 buck to fix that phone and then in two more years or so its going to be vintage I would just spend the money towards a new one
