Sudden battery drain on iPhone 17 (iOS 26.3) – 100% battery health
I want to know if anyone else is having a similar experience right now. For the past few days, my iPhone 17 (bought on May 11) has started losing battery really fast – it even drops 10-12% overnight while completely idle.
I didn't have any issues before this, and I used to charge my phone just once a day. My battery health is still at 100%, and I haven't updated iOS since I bought the phone, so I'm currently running iOS 26.3.
I have no idea what could be causing this or what to do next. Is anyone else experiencing this, and does anyone have a solution?
