My roughly two-year-old iPhone 15 Pro Max suddenly became completely unresponsive. It was around 70% charged when I went to sleep, but a few hours later the screen was totally black and the phone would not turn on. I've tried quickly pressing Volume Up, then Volume Down, and holding the side button several times. I've also tried multiple working cables, power adapters, outlets, and power banks, leaving it connected for one to three hours at a time. The phone is running the latest iOS, has no visible damage, and still shows no screen, vibration, charging symbol, or other response. I need it for work and am currently using a computer to ask for help. What else can I try before taking it in for repair?

A phone that was around 70% charged shouldn’t normally die overnight, so an unexpected hardware or battery fault is possible. Before traveling to a service location, contact Apple Support or an authorized repair provider to ask about diagnostics, mail-in service, or a closer option. Make sure you have a recent backup if one exists, since repair or replacement procedures can sometimes affect the data.
If the battery fully drained or the charging circuit stopped working, the phone can look completely dead. Leave it connected to a reliable wall charger for 30–60 minutes, then try the force restart again: press and release Volume Up, press and release Volume Down, then hold the side button for up to 30 seconds. It may also be worth checking whether a computer recognizes the phone while it’s connected. If there’s still absolutely no response, a hardware problem is more likely.
Since you already tried several chargers and left it plugged in for hours, a normal empty battery is less likely. A failed battery, charging port, power-management component, or even a faulty side button could be responsible. If the computer doesn’t detect it and the force restart produces nothing, service or repair is probably the next step.
I did try charging it for one to two hours, then again later with different cables and power adapters. I’ll check whether the computer detects it, but so far it has shown no signs of life.
