How to replace the iPhone 5s battery

A bad battery can severely diminish how long you can go on a full charge. If you own an iPhone 5s and either didn't opt for AppleCare or just prefer doing things on your own in order to save some money, a DIY battery replacement isn't terribly difficult. Not only that, buying the battery on your own and replacing it costs a fraction of what you'll pay for an out of warranty repair. So if you've been experiencing less than stellar battery life, we can help you replace your iPhone 5s' battery in under 30 minutes!

What you need to DIY replace an iPhone 5s battery

You'll need some tools and parts in order to repair your iPhone 5s. iMore recommends using only quality and genuine parts from a reputable supplier like iFixYouri. They have quality parts, tools, and much more for all your repair needs.

  • Replacement iPhone 5s battery
  • Suction cup
  • 5-point security screwdriver
  • Standard #000 Phillips screwdriver
  • Spudger tool
  • Razor blade
  • iSesamo Opening tool (not necessary but awesome for prying up cables and getting under adhesive)

1. Power off your iPhone 5s

Before performing any repair on any device, always remember to power it off. Simply hold down on the Power button until you see Slide to Power off. Once you're sure your iPhone 5s is turned off, proceed to the next section.

2. Remove the two security screws on both sides of the dock connector

There are two security screws that secure the screen to the frame and they sit on each side of the dock connector. Use your 5-point security screwdriver to remove them. They are both the same size so it's okay if you mix them up.

3. Remove the display assembly

  1. Place your suction cup slightly above the Home button assembly and secure it to the screen.

  1. Holding the iPhone in place with one hand, gently pull upwards on the suction cup until you free the bottom of the screen but do NOT pull up all the way at this point as a cable running to the Touch ID sensor is still connected. You only want to separate the screen about an inch at this point.

  1. Now that you have a clear view of the cables, use the pointed edge of your spudger tool in order to carefully remove the metal shield covering the Touch ID cable.

  1. Make sure you don't lose the metal guard that covers the Touch ID connector.

  1. Again, use the pointed edge of your spudger tool in order to disconnect Touch ID.

  1. You can now safely swing the display up more in order to see where it is connected to the board.
  2. Remove the four screws holding down the shield that covers the display cables. To do this, use your #000 screwdriver.

  1. Once all four screws are removed, carefully remove the shield and set it aside.

  1. Now use your spudger tool in order to remove the three cables shown in the image below. You'll need to remove the two off to the far right in order to reveal the third and final cable, which sits below them.

  1. The display assembly should now be free from the body of the phone. Go ahead and set the display assembly aside.

Note: We used the suction cup method here but note that if you can't get a firm grip with a suction cup, you can use a razor blade or the iSesamo opening tool. Carefully work your way around the bottom of the phone between the frame and display assembly with a razor blade or the iSesamo Opening Tool until you can gently pry up using the flat end of your spudger tool. We recommend using plastic razor blades if you can find them since they won't cause damage to the finish of the iPhone's frame.

4. Replace the battery

  1. Remove the two screws holding down the battery cable using your #000 Phillips screwdriver.

  1. Gently lift the battery shield out of your iPhone 5s and carefully set it aside.

  1. Use your spudger tool to carefully pry up the battery cable.

  1. Along the bottom of the battery above the dock, there is an adhesive tab. Use the pointed end of your spudger tool to unfold it.

  1. Pull on the tab at both sides just enough to where you can use scissors to put a cut in the center.

  1. Starting on the left side of the iPhone 5s battery, carefully start pulling the adhesive. It should start coming loose from underneath the battery. You'll hear a creaking/cracking noise. This is normal and is just the adhesive pulling up from the casing.

  1. Slowly and carefully pull sideways and along the left hand side of the battery. Take care not to tear any components. At the same time, don't pull too quickly or the adhesive tab will tear, making it hard to get the rest of it out.
  2. Perform the same action along the right side of the iPhone 5s battery. Take tremendous care not to snag cables or the logic board. Pull away from the logic board.
  3. Keep a finger or two over the battery as it may come with the adhesive when you're done removing it.
  4. Once both sides of the adhesive strip are removed, simply lift the old battery out of your iPhone 5s.
  5. Your new replacement battery should have adhesive pre-installed on the back of the battery. If it doesn't, use two strips of double-sided tape that are a little shorter than the length of the battery. This will work just fine.
  6. Place the new battery in your iPhone 5s.
  7. Replace the battery cable on the logic board.

  1. Replace the battery shield and the two screws you removed earlier.

5. Replace the display assembly

  1. Reconnect the three cables shown in the image below, starting with the cable to the far left, which sits underneath the other two.

  1. Replace the display shield using the four screws and your #000 Phillips screwdriver.

  1. Re-connect the Touch ID cable to the logic board. The easiest tool to help you do this is the pointed end of the spudger tool.

  1. Replace the Touch ID shield that sits over the cable.

  1. Carefully line up the top of the display into the top of the frame.
  2. Snap down the display until it clicks into place.

If the display doesn't want to go back down, do NOT force it. Instead, be sure that the top is lined up correctly and that you aren't snagging any cables. There should be no resistance when snapping it back into place. If there is, you aren't lining it up correctly.

6. Replace the dock connector screws

Use your 5-point security screwdriver to replace the two dock connector screws that sit on either side of the dock.

7. Test the new battery

After you've finished assembling your iPhone 5s, it's safe to turn it on. In order to test the new battery, perform the following steps:

  • Fully charge your iPhone 5s and make sure it doesn't get any warmer than usual, as that could be a sign of a defective battery
  • Monitor usage over the first few days with the replacement battery to make sure your battery life has improved

If all of the above checked out okay, you're good to go!

  • That is a great explanation on how to do it right. I might just tackle this job now that I seen your break down.
    Thank You,
  • Has iMore ever written a post about iPhone broken screens? Not as a fix-it article, but just as a general topic. Cracked screens seem to be an epidemic. I see them everywhere. Are iPhones known for especially fragile screens? Or are iPhone owners just particularly clumsy? Or is it that there are just more iPhone owners out there?
  • A screen is a screen and glass will break. I see just as many cracked Galaxy S phones as I do iPhones.
  • i once tried to replace the battery on an old ipad 1, it looked easy enough on the video and after my kit arrived i set to work. Lets just says its not as easy as it looks, i ended up just about killing it, it never really worked the same when i got it back together, i didnt care so much since it was a dinosaur, but id NEVER try to fix my 5s myself if something were to happen to him, hes just too important to me!

  • I have two iPhone 5s... one (A) was completely dead and the other (B) wouldn't hold a charge for more than a few hours. I bought a replacement battery on ebay and replaced the battery in iPhone B with the new battery. I then took iPhone B's battery and put in iPhone A. Afterwards, iPhone A turned on and worked fine. iPhone B wouldn't turn on at all. I assumed that I must have missed a connector somewhere, so I reconnected everything and it still wouldn't turn on. So I took the new battery and put it in iPhone A and put iPhone B's original batter back into iPhone B. Now neither phone will turn on. I removed the batteries from both phones and plugged them in and tried to turn them on, and still nothing. Can a reaplcement battery ruin an iPhone? because that's what seems to have happened.
  • It is a nice tutorial with great images indeed. But replacing battery on iphone 5S is full of risks. If you happened to cut the touch id cable, u gonna end up right there. If you mistakenly ripped battery cable, another loss. If your body or clothes static got discharged over ur iphone inside, u gonna kill it right there or it gonna die in a few days. If u put too much pressure while pulling out the screen, hou may crack open it. Or the digitizer will probably loosen out from the disay frame. I learnt these stuff while visiting The tech demonstrated how thousands and thousands of iphone 5S and othe iphones are killed each day. We all want to save money and inwanted too. But i ended up snapping out the touch id/home cable. Now my touch id is useless. After payinf for its replacement touch id is only useful as home button. My suggestion is: do not try battery replacement job at home. You are risking too much. The professional place like Apple Repair Club replaces it in less than 10 minutes and also provides warranty at the fraction of cost. You can approach any dedicated Apple repair shop that maintains ESD in their work desks. I also urge: do not get field tech help. They also cause static discharge inside your phone and inject ur iphone with a slow poisioning of ESD. YOUR phone may seem repaired momentarily but will develop issues shortly. Electronic devices like iPhones must be handled with care and in an ESD controlled or maintained environment. Hope it helps to iPhone owners excited or intending to do battery replacement on their own. If the post writer considers this comment, it is worth mentioning here so that it may help minimize the iphone damages while performing self battery replacemet at home.
  • Great video a REAL TRUE EXPLANATION OF THE PROCEDURE REQUIRED. Like the way you pace the steps and the camera angles. I could use you at work to develop training. Thanks
  • Many thanks to the writer and photographer for the awesome pictures ... much easier to follow than rewinding a video a million times! I am not overly technically inclined but I'll be darned if I was gonna replace my son's phone before I get to upgrade from my iPhone 4 (no "s" either). His may have been an earlier version, there was no touch cable, just a connection plate, so nothing to disconnect (didn't stop me from looking for five minutes though). Anyway, love the high quality how-to, great work :)
  • omg this is not for the faint hearted... A missing note on your instructions is to push the battery to the far left, to give room for the kink in the battery cable to fit down between battery & logic board; I had put mine too close, necessitating trying to remove a 3m double sided stuck battery. It wasnt pretty & I punctured it with my flathead (both spudger tools snapped already), there were fireworks & smoke!
    Luckily I had a second..
    Yes theres so much room for error here, as someone earlier commented. I was aware of my clumsiness the whole time, and am surprised its now working fine.
    It's very complex & much harder than replacing an iphone 4. But Apple cant beat us.. yet!
