Can the battery of the iPhone 15 series be boosted?

Please I want to know if an iPhone 15 series battery can be boosted? Cos I bought the fairly used iPhone 12 Pro Max recent with 89% battery health 4month ago now my battery health is 75% that shows the battery as been booted, so am thinking of upgrading to a fairly used 15 series that’s why asking?

The battery cannot be "boosted".


The battery can be replaced at the Apple Store / Genius Bar or at an authorized Apple service shop.


You can find a list of authorized shops in your area using this link: Find Locations


About $100 (U.S.)


If you purchase a refurbished iPhone 15 directly from Apple, it will come with a new battery.

Stick with buying a refurbished phone from Apple if you are looking for a phone at a slightly less cost. These will have a brand new genuine Apple battery.

The risks of buying from a third party are too high. Not only could the device had service from an unauthorized provider where a non-genuine battery has been installed, you may also face far more problems as detailed here:

Meaning?? Make clear please

If you purchased a device from a third party where it had been opened by an unauthorized service provider for a battery replacement or any other purpose, Apple can choose to not provide any service if you took it to them for a problem.


If you are looking to avoid problems buy the refurbished phone from Apple, otherwise you are taking a huge risk for many reasons outlined in the link provided earlier. Seen too many people who went down that road and ended up with a device that is not usable and no means to get their money back.
