Problem 1: iPhone 7 won’t charge and turn on
I have the iPhone 7. My phone was on 1% before it completely went dead. It went dead and when I made it home, I went to put it on the original Apple lightning cable that came with the phone and it appeared to be charging. Unfortunately, it was not charging being that a hour later the phone never powered on. I have tried to restart it using the power and volume button but no signs of nothing there. I took it off for a while and plugged it back in, this time the battery icon did not pop on the screen at all. The phone does not even warm like it usually would when charging. I know for certain it isn’t the charger because I tried it on my iPad and my sisters iPhone as well and it worked perfectly. — Diamond Kidd
Solution: Hi Diamond. A Lithium-based battery, like the one in your iPhone, does not really lose all its power, even when the battery status percentage says 0%. This is because a Lithium-ion battery needs small amount of power to keep its circuits alive for the next charging session. Normally, this residual power in your phone’s battery can last for days before you charge the device again. In some rare cases though, the rate of power drain can become abnormally fast that the residual power may be lost quickly before you can recharge. In this case, the battery can be rendered totally dead.
If your phone no longer charge or turn back on after leaving it connected to the charger for hours, that’s a clear indication that the battery may have died. It may be due to the scenario we described above, or for some other reasons.
To check, you need to let Apple take a look at your phone at their service center. There’s no software trick that you can do to revive a dead battery so repair is the only way to go.
Problem 2: iPhone 7 turns off on its own when it gets warm
Hi. I have an iPhone 7 plus and have had it for a year and 3 months. I can’t say I have had any issues with it until now while I’m on holiday in Mauritius. As of yesterday it has been turning off and just showing the Apple logo as if its starting up again but continually does the Apple on and off. I’ve managed to get it to work now for the time being while in a very cold air conditioned room but it’s being very temperamental and I’m not sure what to do. Im worried that it may turn off completely and I won’t have it for the rest of my holiday.
It’s starting to get warmer in my hands as I’m typing now so i’m gonna have to be quick. I think there is an Apple store on the island of Mauritius but it’s a long way from where I’m staying and I’m worried they might not be able to repair or replace it as I’m not in my home country (UK) although I do have insurance cover through my network provider. Please can you help me. Thanks so much! — James Tainted_blade
Solution: Hi James. If your iPhone gets warm or hot before eventually turning itself off, that’s an indicator that it may be overheating. Overheating can be an indication of a software glitch, or an on-going hardware malfunction.
To see if it’s due to a software problem, consider wiping the phone with iTunes or iCloud. Obviously, you want to do the procedure in an airconditioned room to keep your phone’s internal temperature low. If you want to wipe your iPhone via iTunes, you’ll need a computer to do it. Make sure that you create a backup of your important files (photos, videos, etc.) before you factory reset your device. Here’s how:
- Open Settings app.
- Tap General.
- Tap Reset.
- Tap Erase All Content and Settings.
- If prompted, enter your passcode.
- Tap Erase iPhone.
Once you’ve wiped the phone clean, let it run for a few hours outside your airconditioned room and see if overheating continues. Make sure that you don’t install any app at this time. There will be two possibilities in this one:
- your iPhone will work normally
- your iPhone will continue to turn off on its own
iPhone will work normally
If your device will work properly after a factory reset and during the observation period, that’s a good sign. It means the problem is most likely due to software bug or poorly coded app. Should the issue return after re-adding your apps later on, that’s your cue that one of your apps is bad.
Contact Apple
If the phone continues to turn off on its own, even when no apps are installed, that’s a clear indication that you have a hardware issue at hand. In this case, you want to contact Apple so repair or replacement can be performed.
Problem 3: iPhone 7 not turning on after repair
Hello there. I have a iPhone 7 which is flashing Apple logo then turning off. I have tried hard reset, cleaning the motherboard, check power button, put in different case. Has had full reset on iTunes back to factory standed try 3 reset modes on iphone it’s will boot and all works but then turns off my be new battery but battery is ok will not’s boot on DC power supply look s as there is not’s enough curgent to boot. — Warren.saunders
Solution: Hi Warren. You have a clear case of bad hardware issue, most probably due to a bad motherboard. Since you clearly are unable to do a thorough hardware diagnostics, let a professional do it for you. At worst, this may result to a motherboard replacement so you want to let someone who does hardware repair for a living check the device for you. Hardware troubleshooting and diagnostics is way more complicated than software troubleshooting so you need a trained technician to do a check on possible bad components. When letting a technician do the repair, make sure to mention the relevant details leading to the problem. In other words, you want tell the technician what happened prior to noticing the problem. In this type of situation, device history is a critical piece of information. For example, if your phone was exposed to heat or water before the problem started, you need to tell that to the technician so they can check the relevant components.
Problem 4: iPhone 7 stuck at Apple logo screen
My iPhone 7 problem is at stuck logo apple. I tried restore and update. Tried to change computer and cable and usb.

After rest again problem again stuck logo ..I need if this problem hardwere I need begen what part in it can start I have expiernce repairing phone this is my job can you help me friends. — K.abieedd
Solution: Hi K.abieedd. The most that you can do to fix an iPhone that got stuck in Apple logo screen is to perform a factory reset. If your device remains unresponsive, or if you can’t do the normal recovery process, you can try recovery thru DFU mode. If that won’t work either, or if you can’t do recovery via DFU mode, then you have a bad hardware at hand.
Our blog does not support hardware troubleshooting and diagnostics so try to look for other sites that may provide you with hardware diagnostics tips.
Otherwise, let Apple fix the issue by sending it to them.
