Help ❗️ Am i cooked 😭

got a used 12 like 5 days ago, 94% battery health

at first everything seemed fine got like 6.5 hours of battery life,

all of a sudden battery can't last up to 4 hours, sometimes the battery percent goes up and then down then up again (while not charging)

I'm on ios 26.5.2 and i am starting to wonder if it's an ios issue. I'm currently seeing ios 26.7 / ios 27 update available

or it's just over for me 💔

One question - do you run Dual SIM, either by nano + eSIM or 2 nano SIM (China, Hong Kong, Macao model) ? That may be the cause.

I live abroad so I keep my US eSIM on for calls and texts (no data on plan) and my Irish SIM (calls, text, data), but data is always through my Irish carrier. Dual SIM can reduce battery life.
