If the battery is completely drained, you could have to let it charge for about 15 mins before you see something on the screen.


Below is Apple's suggestion for this problem, if it doesn't fix it then you'll have to send it in for service.

iPhone: Hardware troubleshooting

Will not turn on, or will not turn on unless connected to power

  1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
  2. Check if the Liquid Contact Indicator (LCI) in the headset jack or dock connector is activated or there are signs of corrosion or debris. Learn more about LCIs.
  3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
  4. After at least 15 minutes, if:
    • The home screen appears: The iPhone should be working. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen User uploaded file. Then unplug the phone from power. If it immediately turns off, seek service.
    • The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    • If something other than the Home screen or Low Battery screen appears on the display, continue with this article for further troubleshooting steps.
  5. If the iPhone did not turn on, try resetting it while connected to the iPhone USB power adapter. To reset, press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until either the Apple logo or the battery symbol appears.
    • If the display turns on, go to step 4.
    • If the display remains black, go to next step.
  6. Restore the iPhone. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
  7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Hi, my girlfriend had this problem yesterday. I tried everything on this thread and nothing worked. I plugged her phone into a mains charger for about an hour and nothing happened (I plugged mine in to, to ensure it wasn't the plug and mine charged). I then plugged it into my laptop and it didn't even register, great. Yet mine did register on the laptop. So, I left hers in charging in the laptop for another hour, yet again nothing happened, nothing came up on screen, no charging icon, no apple sign, nothing, just a blank black screen.


The other problem she has is that the top lock button is completely broken and is un-pressable which made full restarting the phone completely impossible, whilst her home button is almost going too (Ridiculous manufacturing from Apple's behalf if you ask me, this also happened to my past iPhone, but I won't go into that now).


SOLUTION:


So this morning I remembered that my phone had gone into safe mode one time and I vaguely remember holding down the home button whilst you plug in the charger (keep the home button held down). So I tried it on her phone, and it WORKED! It came up with a red battery icon, knowing that the battery had drained completely so I've left it charging and it's all back to normal now.

Option 4 worked for me....

    Ok, this is too late to help, but I thought I'd answer anyway in case someone else finds this post whilst searching for the problem. Here's how to fix it:

    Lithium batteries have protection against over-discharging, they do this by breaking the circuit if the voltage drops too low to prevent further drain. Unfortunately, once this has triggered, you can no longer put charge back into the battery because the battery is disconnected internally, so no matter how long you leave the phone on charge, it remains disconnected and flat.

    You only need to get the voltage in the battery to raise a percent or two to reconnect the protection circuit so that it will charge again and you can do that by warming up the battery. You may get away with leaving the phone overnight in a very warm (hot) place, such as on top of a hot water tank, however a more efficient way is to remove the battery and heat it up until it's quite hot with a hairdryer on its hottest setting. Heat it for a good 5-10 mins so that the hear soaks right through the battery and it feels hot to the touch, this will raise the internal voltage enough to reconnect the protection circuit. Immediately reconnect the battery into the phone and put it on charge. After about 10-20 mins, enough charge should get back into the battery to fire up the phone and it'll come back to life.

    I've done this a few times now on various different models and it always works. Hope it helps yo

    So I just had a problem with my iPhone 4 charging. When I plugged it in, it would make the charge jingle but the plug would show up in the battery like it was fully charged (I think it may also show up when charging with unsupported charger) instead of the charging spark (or lightning bolt thing) that usually shows up when charging. Lucky for me I had a spare iPhone battery lying around and swapped it out. This was after I tried turning my phone off multiple times and doing a hard reset, which didn't fix the problem. Anyway, the new battery fixed the problem, and now it charges just fine. Im not sure what was wrong with my old battery, it is a few years old, but it seemed to hold a charge just fine before it just stopped charging. If anyone else has this problem I would recommend trying a hard reset first and then if that doesn't work try swapping the battery before you go messing with the dock connector since it is a lot easier.

    Man you saved my day, lots of time and $$$. I thought my Iphone5 was dead even though I knew it was 45% charged. Tried #5 and it came back alive with Apple Logo and showing 90% charged (as it was plugged to the charger). Thanks a million 🙂🙂😎
