I replaced my battery October of last year at around 82% at the Apple Store. Saw a big improvement for day to day use as far as longevity goes. Currently at 89% and still going strong. I’d do it if I were you. Answer from 5izeUp on reddit.com

That would still show as 100% (even though it was actually 110%), but as it aged the health would stay at 100% until it fell below 3200 MaH. This would appear to you as if the battery had fabulous life, until suddenly it didn’t. ... Then you don't know how long that phone had been sitting ...

r/iPhone13Pro on Reddit: Whoever has already replaced their battery health, did it really improve performance and things overall significantly?
August 29, 2025 -

I’ve had my iPhone 13 Pro since April of 2022. Since then my battery health has degraded from 100% to 79%. I just would like to know if a replacement of the battery would have a significant improvement on performance and everything overall. I would really appreciate some insight on this. Thank you!!!

I’d also like to mention, I may have depleted my my battery health way faster than on average, I think it may be because I used a plug with a much higher voltage input which probably affected my battery massively.

r/iPhone13ProMax on Reddit: iPhone 13 Pro Max Battery Health Decline - Frustrating! Anyone Else?
September 20, 2024 -

Ever since the iPhone 16 event on September 9th, I’ve noticed something super frustrating with my iPhone 13 Pro Max – the battery health. It was sitting at a decent 87% before the event, but now, just a little while later, it’s down to 84%. Seriously? Three percent in less than two weeks?

I’ve been super cautious about charging habits and don’t use my phone in extreme temps, I charge my phone in the morning only to 90%, and don’t use MagSafe, so I’m really not sure what’s going on here. It feels like with every new event, older models just start declining faster. Anyone else seeing this? Is this just normal wear or is it tied to these iOS updates?

I know it’s normal for batteries to degrade, but this feels way too fast. At this rate, my phone is going to need a battery replacement sooner than I thought. Should I be worried, or is this just the usual decline as it gets older?

Let me know if anyone else has experienced this sudden drop or if there’s anything I can do to slow it down.
