The iPhone has a number of features that draw power even when the phone is turned off. These features include the backlight, the clock, and various sensors. When the battery is low, these features can draw enough power to prevent the phone from starting up.

There are a few things you can do to try to get your iPhone to turn on faster after it has died. First, try charging your phone for a while. If that doesn’t work, you can try holding down the home button and the power button at the same time until your phone turns on. If that still doesn’t work, you may need to take your phone to an Apple store or another service center to get it fixed.

If your iPhone has been completely drained of power and has been sitting unused for months, it will likely take a significant amount of time to charge it back up to 100%. Depending on the battery health of your device and the charging accessories you use, it could take anywhere from a few hours to a full day to get a full charge.

There are a few reasons why your iPhone might not be turning on after it died. One possibility is that the battery is too drained and needs to be charged before the phone will turn on. Another reason could be that there is a problem with the phone’s hardware, in which case you might need to take it in for repairs.

The iPhone 13 will take about 3 hours to charge from 0-100%.
