iPhone 7 battery draining even on standby...any solution?
My iPhone 7’s battery health is 83%, but a couple of weeks ago it started draining, like in a test, I restored it, pulled the sim, no iCloud id, no apps, just connected to Wi-Fi, charged to 42% and after about 8-10 hours it was dead. No activity. I have restored/updated multiple times.
After that I went to an Apple Authorized Center, they ran diagnosis, and told me battery tests passed and since its 83% they won’t replace, and told me its most probably some board/port issue. They offered me replacement at full price (around 420$, which doesn’t make sense to me).
I don’t know of any good repair shop in my area. Any idea what could be the issue? Or how should I proceed with this phone? It’s useable to some extent, or at least when I’m at home. Will continuing using it can cause serious damage etc?
Es esta una buena pregunta?
