iPhone Won’t Turn On After Battery Replacement? Here’s The Fix!

You just had your iPhone’s battery replaced, but now it isn’t turning on. No matter what you do, your iPhone is unresponsive. In this article, I’ll explain what to do when your iPhone won’t turn on after a battery replacement.

Hard Reset Your iPhone

It’s possible your iPhone’s software has crashed, making the display appear black. A hard reset will force your iPhone to restart, which would temporarily fix the issue.

The hard reset process varies depending on which model iPhone you have.

iPhone SE 2, iPhone 8 And Newer Models

  1. Press and release the Volume Up button on the left side of your iPhone.
  2. Press and release the Volume Down button.
  3. Hold down the Side button on the right side of your iPhone.
  4. Release the side button when the Apple logo appears.

iPhone 7 And 7 Plus

  1. Simultaneously hold down both the power button and volume down button.
  2. Release both buttons when the Apple logo appears.

iPhone 6s And Older Models

  1. Simultaneously hold down the power button and the Home button.
  2. Let go of both buttons when the Apple logo appears.

If the hard reset worked, that’s great! However, you’re not done yet. Hard reseting your iPhone doesn’t address the underlying software issue that caused the problem in the first place. If you don’t address the deeper issue, the   problem may return.

Backup Your iPhone

Backing up your iPhone will ensure that you a saved copy of all the information on your iPhone. You can backup your iPhone using iCloud, iTunes, or Finder, depending on the software your Mac is running.

Check out our guides to learn how to backup your iPhone:

DFU Restore Your iPhone

A Device Firmware Update (DFU) restore is a deep reset on your iPhone. This restore erases and reloads your iPhone’s software and firmware, line by line.

The restore is done differently, depending on which iPhone you have. First, grab your phone, a charging cable, and a computer with iTunes (Macs running MacOS Catalina 10.15 will use Finder instead of iTunes).

iPhones With Face ID, iPhone SE (Second Generation), iPhone 8, And 8 Plus

  1. Make sure your iPhone is connected to your computer via the charging cable.
  2. On the left side of your iPhone, quickly press and release the volume up button.
  3. Quickly press and release the volume down button right below it.
  4. Press and hold down the side button until the screen is completely black.
  5. Once the screen is black, simultaneously press both the side and volume down buttons for five seconds.
  6. Let go of the side button while still holding onto the volume down button until iTunes or Finder detects your iPhone.
  7. Follow the on-screen prompts to restore your iPhone.

iPhone 7 And 7 Plus

  1. Connect your iPhone to your computer using a charging cable.
  2. Simultaneously hold down the power and volume down buttons for eight seconds.
  3. Release the power button, while continuing to hold onto the volume down button.
  4. Let go when iTunes or Finder detects your iPhone.
  5. Restore your iPhone by following the on-screen prompts.

Older iPhones

  1. Plug your iPhone into your computer using a charging cable.
  2. Simultaneously hold down both the power button and the Home button for eight seconds.
  3. Release the power button while continuing to press down on the Home button.
  4. Let go when iTunes or Finder detects your iPhone.
  5. Follow the prompts to restore your iPhone.

Hardware Problems

If a hard reset or DFU restore didn’t bring your iPhone back to life, the problem likely arose from a botched repair. The person that repaired your iPhone probably made a mistake while installing the new battery.

Before taking it back to be serviced, make sure that it isn’t just a display issue. Try turning the Ring/Silent switch on and off. If you don’t feel a vibration, then the iPhone is turned off. If it vibrates, but your display remains dark, the problem might be your screen rather than the battery.

Repair Options

After confirming whether it’s a display or battery problem, your best bet is getting an expert. We typically don’t recommend repairing your own iPhone unless you have a lot of experience.

First, try going back to the original repair center for the restoration, if possible. You probably won’t have to pay anything extra.

However, we understand if you don’t want to go back to the repair company that broke your iPhone. Puls is another great option. They’ll send a certified technician directly to you in as little as an hour.

You can also try bringing your iPhone to Apple. However, as soon as the technician notices the non-Apple certified part, they won’t touch your iPhone. Instead, you’ll have to get your entire iPhone replaced, which will be more expensive than the other repair options we’ve mentioned.

If you decide to take your iPhone into an Apple Store, make sure to schedule an appointment first!

Getting A New Phone

iPhone repairs can be expensive. If the repair company you visited screwed up, your iPhone may be permanently damaged. A better option might simply be replacing your old phone.

It seems from the comments that Apple iPhones will not work with 3rd party batteries.

Hi, I took my Iphone 7 to get the battery replaced by a local service. My plug connection was loose as well and thought they could diagnose the problem. When they put a new battery it would not start. So they put the old battery back in and I took it home and plugged it in. Eventually it did start to recharge and I was able to turn it on. I took the Iphone to Best Buy the next day since they have certified apple service and they replaced the battery and now it won’t start. They want to give… Read more »

I brought my 6splus into Apple for a new battery (as recommended) and during installation they told me the phone will not turn on. They sent it in for repair and sent me an email saying they cannot repair it they will replace it. I haven’t picked up the replacement yet so I don’t know which model I’m getting but whichever it is I need to restore my backup to the new phone. Problem is, I can’t find the piece of paper I wrote my backup password on. Can you tell me how to retrieve my ipone backup from a… Read more »
