Hi everyone! My girlfriend has an iPhone 13 Pro that's currently running iOS 15, and she's nervous about updating it because her battery health is at 78%. She's concerned that updating might worsen her battery life. I want to help her with this update and possibly get her a new battery as well. What do you think is the best approach? Should we take it to the Apple Store or update it via iTunes/Finder? By the way, she has iCloud backups enabled, so we're not worried about losing any data. Thanks for any advice!

It's definitely smart of her to be cautious about updates, especially with a lower battery health. I recommend making a full encrypted backup on Finder first—it's a good safety measure. You can update the phone through Finder after that's done, which usually goes smoother than over-the-air updates. Just make sure to choose the right IPSW file for her model if you go that route! Also, she can find IPSW files on various websites that list them, but it’s usually easier to do the update directly via Finder without that step. Good luck!
Honestly, if her battery is at 78%, she might want to consider replacing it anyway before doing the update. Apple suggests replacing batteries when they drop below 80%. The newer iOS versions can drain the battery faster, so it's best to get that fixed first. You can either go to an Apple Store or an authorized service provider for a battery replacement, and yes, it might cost a bit, but if you're living at home now, it’s worth doing while you can!
Thanks for the advice! What would you say is the most cost-effective way to handle the battery replacement?

Got it, I updated my post concerning the backups. I appreciate the tip! How exactly do I find the IPSW file if I choose that option? Any specific site you recommend?
