If your Samsung Galaxy S9 can't get through a day any more, that's the battery ageing — not the phone giving up. It's one of the cheapest repairs we do and it makes an old phone feel new again.
On your Samsung Galaxy S9, check Settings › Battery › Battery Health. Below about 80% maximum capacity, iOS starts throttling performance and the phone will shut down early when it's cold. That's a battery, not a fault.
If the screen is lifting at the edge, stop charging it and bring it in — a swelling cell is a fire risk, and left alone it will push the screen off and turn a battery job into a screen job too.

Will Battery Health still work afterwards?
With a genuine Apple battery fitted by us as an Apple Independent Repair Provider, yes — it calibrates properly and the readout keeps working. With an aftermarket cell, iOS may show a service message even though the battery is fine. That's the honest trade-off between the two prices.
Is it worth it on an older phone?
Usually, yes. A battery is a fraction of the cost of replacing the phone, and it's the single change that makes an ageing Samsung Galaxy S9 usable again.
How long does it take?
Typically same-day if you walk in, or 1–3 working days by post.
Experienced technicians, genuine parts where it matters, and an honest answer before you spend a penny.
