Introduzione
Use this guide to replace the battery in your iPhone 15 Plus.
iPhone batteries are rated to hold 80% of their capacity for up to 1000 charge cycles. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery.
You'll need replacement battery and back glass adhesive to complete this repair.
If your battery is swollen, take appropriate precautions.
Note: Due to Apple's parts pairing restrictions, on iOS 17.6 and earlier, you may receive warnings about your replacement part and lose access to battery health data, but your new battery will otherwise work normally. On iOS 18 and newer, calibrate authentic Apple batteries using Repair Assistant.

I guess I don't get the rationale here. We come to iFixit, ostensibly to save money. Apple will replace the battery of virtually any iPhone for $69-$99, right? So, I buy an iFixit battery kit for $50. Then I have to purchase a heat gun or hair dryer, another $20-$25, then the back panel adhesive (which I can't find here for a 15 plus), so that's another $6, then I possibly need some 90% isopropyl alcohol for the battery adhesive (which is also a run to a store with time and money spent), and those things alone come to $85-$90. Which brings me to the point: Why would I bother to do a 1 hour (minimum) repair with all the fiddlies, and all the possibility of messing it up, when for about $10 service cost above the iFixit cost, I can just have a CERTIFIED GUARANTEED repair done at Apple. Right?
Everyone has a hair dryer in the house. And the apple repair is mor like 99 than 69, at least in my country. And I would pay no problem but they expect me to leave the phone and after that they order the battery and until it is delivered and repaired it takes a total of 10 days or so time where I don’t have my phone. Last time I just bought a new phone because of this but I got the ifixit battery replaced for a friend and he was very happy that it took 2 hours and he has the phone available same day. So yea… maybe it is not for you but it certainly is for a lot of people. Thank you ifixit for having an alternative.
So, do I not need to order a new adhesive seal for the back glass when my device is reassembled?
How about Step 19? Those photos don’t clearly illustrate the process of sliding that bracket up to remove it? Please be more clear with your photos if there is a specific “process” to be followed. You did a great job a few steps later with the other bracket.
I’ve done this before so it won’t be so confusing, but, I can imagine someone who’s never done this being super confused and worried they’re going to mess up their iPhone because of us unclear instructions.
To those saying this saves you no money due to the tools - fine, don’t do it. Go pay Apple extra $50 to have them do it. The tools that come with this kit are practically given away compared to the price of a battery alone and the heat gun or hair dryer can easily be substituted with anything that can heat up enough to soften the adhesive. I’ve used heating pads and microwaveable rice bags to do this.
Just read the instructions, be patient, and GO SLOW.
