How long does an iPhone last before it is completely dead? Several factors can impact how long an iPhone will work after it has completely run out of power. When used, an iPhone may take four to five hours to fully recharge. This charge time increases if the phone is in use while it is charging. In addition, it can damage the battery if you forget to fully charge it after it reaches 80 percent.
The first step to troubleshooting an iPhone that’s completely dead is to charge the device. If you’re using a new iPhone, it will need to be plugged in for at least 15 minutes before it comes back to life. If you don’t want to wait that long, you can try manual booting. Press the Home and Sleep/Wake buttons at the same time, then release them simultaneously. The screen should then show the Apple logo.
You can revive a dead iPhone by performing several methods. If you can’t see the battery meter, it’s probably due to a hardware or software issue. If it doesn’t turn on after 15 minutes, you’ll probably have to reset the phone. In most cases, a dead iPhone can be revived by simply holding the home button for 10 to 15 minutes, depending on the model. During the charging process, you’ll see the Apple logo and the device should boot up.
If you don’t see the Apple logo when you connect the iPhone to the computer, you can connect it to the original charger. It will take several tries to get it to work, so you’ll have to be patient. Make sure to connect your iPhone to your computer through a USB cable, or else it won’t get recognized. If you have the DFU mode, the iPhone will not show the screen, and it could have been a hardware issue.
Depending on the usage, your iPhone may require a charge for a couple of minutes before it is fully dead. Once the battery has died, it will be a black screen with no access to the functions. Wait until the icon turns red again, then try again. After about two minutes, it will be fully charged and you should be able to use it again. It’s not uncommon for an iPhone to have a battery life of about two hours when it’s completely dead, but the icon will indicate that the phone is almost completely dead.
While your iPhone’s battery is nearly completely dead, you can still recharge it by using a USB port to plug it into a computer. A USB port connected to a computer will recharge an iPhone quickly, but this process requires a longer time. Once the iPhone reaches the threshold of 3% or 5%, the icon will indicate that it’s ready to be recharged. This process may seem complicated, but it’s worth it in the long run.
