How to replace your iPhone battery: The ultimate guide

If you've got an iPhone that's getting on in years, your battery isn't going to hold a charge like it once did. Apple is currently offering a $29 battery replacement program for aging batteries found in the iPhone 6s, SE, or 7, but many of its stores are backlogged on repair requests; you may have to wait up to two months to get your phone's battery replaced.

Luckily, undergoing an iPhone battery replacement is one of the easiest iPhone repairs you can do for most older models. As long as you've got a little bit of patience, we can help you bring new life to your old iPhone!

PSA: Use the right batteries when attempting a replacement repair: When replacing a battery in your iPhone, or any electronic device for that matter, it's very important you use high quality or OEM batteries. While using aftermarket components may not be unsafe in some circumstances, a battery is a huge exception. We recommend only using reputable suppliers for battery replacements, like iMore's partner iFixYouri.

While Apple now has a number of ways you can address this problem including a new Battery Health section in Settings, if your battery has dropped below peak capacity, it's worth considering a replacement.

As far as symptoms, a bad battery in an iPhone 5c can produce overheating issues, sporadic shutdowns, and dismal battery life.

  • Any other reputed sellers out there who ship international? I tried contacting eTech Parts but they do not ship to India. Thanks!
  • Awesome guide, thank you
  • Thanks for this. It's more than a year that I'd bought an iPhone 5, and I'm having the kind of problems you describe here :( Just in time Allyson. Thanks :)
  • Great guide! Where are the instructions for the iPhone 5s? Sent from the iMore App
  • Those will come too. Stuff like this wouldn't apply yet due to warranty. ;) Sent from the iMore App
  • Are there any higher power replacement batteries out there than the original battery? Ones that would offer more runtime? (I have an iPhone 5).
  • Sure there are. I don't typically recommend them as they aren't OEM. The safest route is to use OEM.
  • Good article. My IPhone 5 qualified for the replacement battery program. Took it to my local Apple store. The necessary diagnostics were run and failed. New battery replaced and diagnostics failed again. Instead of shipping my phone out I got a new replacement. Sent from the iMore App
  • Can you recommend other suppliers? eTech shipping charges are nearly as much as the parts when purchasing 1-2 parts. Amazon has lots of vendors, and (since it's Amazon) MUCH better shipping rates. If they claim "OEM", can it be trusted? Thanks.
  • I only recommend what I've personally had experience with. I use eTech because they have very low failure rates, quality parts, and stellar customer service. I'd rather pay more for that than save a few bucks and potentially damage a device. I'm sure there are others that are ok but there are lots that aren't. I just won't recommend anything I don't have experience with personally. Sent from the iMore App
  • How do you know you're getting an OEM battery if youre buying it from ebay or something. I mean yeah they may say it is OEM. safest thing to do is take it to Apple and have them replace it. If you have a iPhone 5 then search "Apple battery replacement program" and the first link will tell you whether you can get a free battery or not. Sent from the iMore App

  • Thank you for this guide - the guide to closing it all up was a nice touch. I replaced my son's iSight camera last night. I had a minor accident when I managed to dump all of the screws onto the floor halfway in but thanks to you I recovered!
