Apple iPhones are expensive precious devices that one would never want to loose, and sometimes this misfortune does hit some people. Many complain that their iPhone won’t turn on without knowing the proper reason behind this condition. If you’re one of them, then don’t worry as there are lots of things you can do to your beloved smartphone before concluding it’s dead and needs to be replaced.
1. Hold and Home Button
In many cases, this simple method has proved successful and has saved pockets and hearts of many people when the Silver colored Apple just pops up on screen before booting. To execute this, hold down the home and sleep/power buttons simultaneously for 10 seconds and if you are lucky this might do the trick. You may also continue holding these buttons for 20-30s but if your iPhone doesn’t show any response in first fifteen seconds then there is a probability that it won’t show it even in hours.
2. Restore Factory settings
Although this option erases all the data and settings on your smartphone, it is a better option than just seeing your iPhone dead. Normally, restoring the factory settings is done by syncing your iPhone with iTunes and then clicking restore. But since your iPhone is not turning on, you’ll need a different technique. Start by connecting your iPhone’s USB cable to Dock connector (Not computer). Now, hold down the home button and connect the other end of the USB to your computer which will automatically launch iTunes from which you can put your iPhone into recovery mode and you will restore you iPhone within no time.
If your iPhone gets to the Silver logo but restarts from there again and again then it is an indication of a problem with the booting system. This often results due to Jailbreaking or updating your iPhone to latest iOS without enough battery life. You can fix this easily by entering into DFU Mode.
A DFU mode stands for Device Firmware Update mode which helps you to make small changes to the software that is exactly responsible for running your device. It is most often confused with Recovery Mode but it is very comprehensive than that. To enter into DFU mode follow these steps
Connect your iPhone with Computer
Since your device is turned off you need to hold down the sleep/power and Home buttons at the same time for at least 10 seconds. Be patient in this step and make sure you hold these buttons for exactly 10 seconds because otherwise, you will enter into recovery mode.
After 10 seconds have passed, let go of the sleep/power button, but keep holding the Home Button.
Now, the Apple Logo will appear on you iPhone but you should not stop holding the home button until recovery warning pops up on your iTunes.
A difference between DFU and recovery mode is it can understand by observing your iPhone screen. If it is black then you are in DFU mode and if shows a cable connecting to the iTunes icon then you are in recovery mode. The latter cases you will need to repeat all the steps and this time you should lay more emphasis on Step 3 and Step 4. It is normal if you don’t get there in first few tries.
Once you are in DFU mode you can downgrade your iPhone iOS in case the new version has created the problem.
4. Proximity Sensor Problem
A proximity sensor is a small sensor on iPhone which helps it to lock the screen when it is near your face. A malfunction in this sensor would simply mean that your phone will be locked even if it away from your face which is a very rare but possible condition. If you’re facing this issue, it can usually be solved through software. In this case, hold down the Home and Hold buttons as outlined above to restart the phone. When it restarts, the screen should be working. If it does the following: Tap the Settings > General> Reset>Reset All Settings. This erases all your preferences and settings on the iPhone, but won’t delete your data.
