1. Charge Your iPhone
Upon noticing your iPhone's failure to turn on, the first suspects are the charging process and the battery. Maybe it is an empty battery or a faulty USB cable or adapter. It could also be a slight software glitch that's causing it not to turn on even on a full battery. Fortunately, connecting the iPhone to a power source can be enough to eliminate this issue.
- Plug in your iPhone and wait a few minutes to see if the charging interface pops up. If you see it, it means your iPhone is okay.
- If step one doesn't work, try charging with a different USB cable and power adapter. Your iPhone may fail to charge because your charger is faulty. Ensure you inspect the cable and adapter for any signs of physical damage.
- You can also unplug the iPhone from the charging socket and power it by connecting it to a computer.
2. Force Restart Your iPhone if it Has a Broken Screen

All processes boot up to start afresh, which solves minor software errors and could be your solution.
The steps you need to take to force restart your iPhone depend on the iPhone's model.

7. Keeping Your iPhone at a Normal/Ambient Temperature
If your iPhone won't turn on and it's extremely hot or cold outside, the reason may be a temperature condition. Once your iPhone cannot regulate its internal temperature, it goes to sleep until it returns to its normal operating temperature. Hence, if your iPhone won't turn on, move it to a place with ambient temperature. The perfect temperature should be between 32°and 95°F (0°and 35°C).
- Remove the iPhone from extreme temperature areas.
- Let it rest for a while and when you feel its temperature is back to normal, try to reboot it.
8. Removing the Liquid
Water is a big enemy of electronics as it tends to cause some of your iPhone's components to fail. This may limit your iPhone from being able to power on and it’s important to remove the liquid to allow your iPhone to dry out.
- Hold the iPhone horizontally so the water inside can pour out, then use a soft, absorbent cloth to dry the outside of your iPhone.
- Eject the SIM card to create a vent for dry air to blow into the iPhone. You may use a fan to blow cool air into the iPhone via the SIM card slot.
- Lay the iPhone in a flat place in a dry location.
- Put desiccants on your iPhone. These are tiny little packets often shipped with items like electronics and clothes. They create a state of dryness in other items.
- Let the water evaporate. Apple recommends waiting up to five hours, but if possible, wait for 24 hours.
- Try turning your iPhone on again. If you waited 24 hours, connect it to a power source before restarting it since the battery is likely dead.
- If your iPhone turns on, back, it up immediately since water damage spreads and it could experience more problems later.
