Troubleshooting iPhone 7 that won’t turn on

I did my own research on this issue, talked with a few people who encountered the same problem, scoured online forums looking for some clues as to why the problem occurs and it seems like there were quite a few owners who experienced this and majority of them were actually able to bring their devices back to life.

If an iPhone won’t turn on without apparent reason, there’s a big chance that it’s actually just a minor issue with the firmware. However, if the device suffered physical or liquid damage, you may need help from an Apple tech. But try to go through the steps below as they may be able to help you bring your iPhone 7 back to life…

 

Step 1: Verify it’s not just a simple system crash

There are times when the iOS crashes without precedent and it’s during these times that the device freezes. Owners who are not used to it or haven’t encountered such a problem before may tend to be panicky even if there’s no reason to. The funny thing is that when they bring their phone to the store, it would only take a minute in the hands of a technician before the phone boots up again and they’re like “OMG! How did you do that?” This is how technicians fix this kind of problem…

  1. Press and hold the Volume Down button and the Power key (sleep/wake button) together for 15 to 20 seconds.
  2. If there’s enough battery left to power the device on, the white Apple logo will appear.
  3. When this happens, release both keys and wait until the device reboots completely.

This is what you call Forced Restart. It’s a simulated battery removal and your iPhone is hardwired so when the appropriate keys are pressed and held, the phone should restart. However, if it’s still not responding after that, then you need to do the next step. Try doing this procedure a few more times if your iPhone 7 still won’t turn on after doing it for the first try. If it’s still not responding after that, move on to the next procedure. 

Step 2: Make sure your iPhone 7 has sufficient battery to power up its components

Perhaps the reason why your phone turned off, won’t turn back on and respond to the soft reset method is because there’s not enough battery left. So, at this point, you need to plug your phone in to charge for at least 10 minutes. Regardless whether the device shows the charging symbol or not, leave it connected to the charger and then do the Forced Restart again but this time while the iPhone 7 is connected to its charger. 

Plugging the charger in will charge your phone but the other thing we want to know is whether your iPhone 7 responds when it detects current flows through the circuits. If it remains unresponsive, then there’s a chance the battery or some of its components are damaged. Or, it may be just a charging issue, so here’s what you need to do next…

  • Physically check the cable for breakage
  • Look into the port on your charger for lint, debris or corrosion that may prevent charging
  • Try to check the pins to see if one of them is bent
  • Check the charging port of your phone for debris and corrosion
  • Try using a different charger

If your iPhone 7 still won’t turn on after this, then move on to the next procedure.

Step 3: Check for physical and liquid damage

First off, it’s your phone so no one would know more about why this thing occurs or what caused it other than you. So, if your phone fell or got dipped in water–even if it has IP67 rating–then it might be suffering from physical or liquid damage.

As to the physical damage, you can actually tell if that’s the case because it will leave a dent or crack on the outside. The liquid damage, on the other hand, is a bit more complicated but if there was an instance that the phone got dipped in water and started acting crazy, then that might be it!

The IP67 rating is actually more of an insurance that your device may not suffer from liquid damage if got dipped in water for a short period of time. But then again, water or any liquid for that matter is unpredictable so there’s always a chance the device may suffer from liquid damage.

Step 4: Call Apple tech support or make an appointment with a tech

As far as troubleshooting is concerned, steps 1 to 3 are all you need to do or try. If the iPhone still won’t turn on after that, then it’s Apple technician’s job to fix the problem.

So, go to the Apple Store and consult with a tech after all, they can recommend a replacement should the problem is beyond economical repair for as long as it wasn’t physical or liquid damage that messed the phone up.

You may also call Apple’s tech support hotline if you still want to do further troubleshooting but please note that the problem isn’t just any app or firmware problem but a power issue–the device isn’t turning on. So, you may not be able to do the troubleshooting methods tech support may want you to do.

  1. I was so worried when my iphone just gave up on me.Was about to take a appointment at apple care and stopped to your article while finding the fix.Soft reset worked like a charm in just 10 seconds.Oh i can’t thank you enough, you saved my time and dollars.Thank you !!

  2. Never dropped it or drowned it just stopped working with a full battery ~ Yes the soft boot did the trick – thank you

  3. I tried many suggestions on many website, including apple support without success. This article got me going in 30 seconds!!

  4. Thank you so much! I dropped my iPhone 7 on a hard tile floor, and nothing appeared to be broken, so I tried turning it on, but it wouldn’t! I looked up how to turn on an iPhone 7 that won’t turn on, and found this. Once again, thank you!

  5. I need to find you and kiss you! I swear! I dropped my phone from literally possibly 2 ft. It has a life proof case on it, The phone has been in the case literally since it came out of the box, I didn’t even touch the phone, I had the salesperson put the case on. I picked up my phone and it didn’t turn on, I couldn’t get it to do anything. Tried rebooting it using the home key and power key. Nothing, I freaked, everything is on my phone and I have 3 different schools who call me for 9 different kids! I can’t not have a phone. I thought surely lifeproof has a similar policy to otterbox where if your phone breaks while in the case they will replace your phone, nope. (not even sure if thats a real policy with otterbox) Then go to check my insurance either I spend $150 to get a refurbished one or $200 to get a brand new one…….AHH i’m not even finished paying it off yet! Then I found you in hopes that there was something else that could be done and sure enough it worked!! Thank you thank you thank you! Now my farm animals won’t starve!

  6. It took me a while to find out that the restart sequence is different now in the iPhone 7. But my friend’s case, we tried to power it on and charged it up to 15 minutes, and nothing……It ended up being a lemon cause when we took it to the Apple store even THEY couldn’t power it on. We ended up getting a new phone for free. So I’m assuming that was a bad one

  7. Holy crap you are a life saver. The Volume down and Power button trick worked instantly. Just saved me a heartattack the day before vacation
