Do you have an iPhone 5 that is turning off randomly before the battery is fully depleted? If so, you're not alone. This is an issue that seems to plague many iPhone 5 owners. In some cases, the issue is software related, while in others, it is caused by a defective battery. Regardless which category you fall under, we can help you fix it!
1. Hard reboot your iPhone 5
If you haven't already, the first thing you should do when you're having any kind of issue with any iPhone is hard reboot it. You can do this by holding down the Home button and Power button at the same time. Don't release them until you see the Apple logo appear on the screen.
If your iPhone 5 doesn't turn on at all, continue to the next step.
2. Plug your iPhone 5 into a charger
Most people that have a defective battery find that when they plug their iPhone 5 into a charger, it will begin charging and then power back on as if nothing was wrong after only a few moments. So if a hard reboot won't turn your iPhone 5 back on, try plugging it in.
If your iPhone 5 turns on, it should begin working normally again. However, this most likely means that the battery is defective and should be replaced either by Apple or by performing a DIY repair on your own.
